Like Oil and Water: The Politics of (Not) Assessing Glyphosate Concentrations in Aquatic Ecosystems

Abstract

Since the International Agency on Cancer Research’s monograph found glyphosate to be a likely carcinogen, the regulatory focus on the chemical has centred on this determinative criterion for regulatory action. Yet, other pertinent factors, such as the effects of glyphosate on fresh and ground water and ensuing effects on biodiversity, have received less attention as legitimate rationales for regulating the chemical. This underrepresentation prevents a wider policy discussion on the environmental and human health effects of the chemical and fails to disrupt assumptions of path-dependently continuing on agriculture’s chemical treadmill. To avoid ad hoc post hoc chemical regulation, we assess four areas of chemical regulatory oversight in Europe with regard to glyphosate affecting water: (1) the undue emphasis on in laboratorio versus in situ testing; (2) assessing single chemicals (isolated glyphosate) versus admixtures (glyphosate plus surfactants and adjuvants) that are used in practice; (3) the tendency to downplay harms to non-human life; and (4) the lack of policy coherence in the existing regulatory framework. Focusing on European Union regulation of pesticide and water policy affecting aquatic environments, we conclude that issues of measurement and priority have become highly politicised in both science and policy, requiring preventative, precautionary frameworks utilising plural forms of measurement.

I. Introduction

Environmental risk assessments often overlook the structural and systemic “grounded social causes of precarity that expose and sensitize people to hazard”.Footnote 1 A chemical’s hazard is derived from both its intrinsic properties to interact and affect biological material in a controlled setting as well as relational harms when that chemical interacts with different organisms and chemicals in admixtures rather than in isolation. Chemical assessments frequently pay more attention to the former rather than latter hazards, possibly underestimating real-world risks. Virtually all chemical exposures occur together with other chemicals, with interactions affecting organisms variously depending on exposure combinations. Especially in different media such as water or soil, rather than being inert, chemicals degrade or potentiate in as-yet unstudied ways. Against this background, this article considers how the legal and policy frameworks for the assessments of glyphosate – the most used herbicide in history – tend to de-emphasise the assessment of its effects on fresh water. Doing so also entails interpreting the limits of current legal frameworks in the European Union (EU) to address the risks of freshwater contaminations by pesticides. This paper claims that the EU regulatory system currently does not adequately protect aquatic ecosystems from pesticide contamination, substantiated through analysing the case of glyphosate.

Agrochemical runoff damage to freshwater systems has been identified as a major threat to wildlife, ecosystems and securing clean drinking water for populations in European countriesFootnote 2 and globally.Footnote 3 Widespread use of fertilisers, pesticides and herbicides in the twentieth and twenty-first centuries is documented in the corresponding chemical signatures found in aquatic environments globally.Footnote 4 Until stronger environmental regulations began being implemented in the 1960s and 1970s, post-war chemical effluent was regularly dumped without reflection or legal restriction, often harming riparian life and sometimes contaminating ground water.Footnote 5 While during this early period of environmental regulation the USA led international policy diffusion on freshwater protections,Footnote 6 by the 1990s Europe had taken the regulatory lead, and it is currently perceived to be at the forefront of water protection, both in terms of regulations and enforcement.Footnote 7 Europe’s embrace of integrated chemical management and policy has allowed for increased environmental health, and through its relation, human health.Footnote 8 Nevertheless, European water quality is in bad shape: together with near-ubiquitous crop over-fertilisation and loss of habitat due to morphological changes, agrochemical inputs are degrading freshwater quality throughout Europe, by some accounts reducing ecosystem functions by over 20%.Footnote 9 Thus, one would expect that glyphosate regulation, in addition to attending to important issues raised regarding direct human health questions, would take into serious consideration how it affects water quality.

Based on the central role for health that water plays, such regulation would draw on the assumed extensive research analysing the risks of glyphosate in impacting the health of aquatic ecosystems. Yet compared to other scientific domains scrutinizing this chemical, there are surprisingly few field studies on glyphosate’s effects in and on fresh water. Most existing research in this area seems to not account for the adjuvants in commercial glyphosate admixtures, such as RoundUp®, leaving out crucial consequences of how chemical mixtures affect various domains. In examining how European law assesses chemical risk in surface water and ground water, this article emphasises the politics and consequences of measuring the ecotoxicity of chemicals like glyphosate in isolation rather than according to their interactions. Focusing on the impact of glyphosate on aquatic ecosystems and the policies around chemicals in water both in the special case of glyphosate and more generally, we hypothesise that the legal and scientific assessment processes are fraught with blind spots. While clearly we cannot look at all of the gaps here, we point out some of the blind spots specifically in chemical regulation (using glyphosate as a model case) in the EU pertaining to effects and interactions with fresh water.Footnote 10

This contribution assesses the discursive and regulatory context surrounding the measurement and assessment of glyphosate’s impacts on aquatic environments, rather than exhaustively weighing the biodiversity impact of glyphosate and its co-constituent chemicals on aquatic life from a natural science perspective. It is structured as follows: in Section II, we start by presenting some data on glyphosate contamination in surface water and ground water; we then offer an overview of the debate that has ensued among scientists and technical regulatory bodies vis-à-vis the methodologies used to assess the effects of glyphosate in aquatic ecosystems. In this context, it has been argued that taking a single-metric approach to detection may predictably pass over other chemical combinations occurring in water (ie from adjuvants, as well as through degradation and reactions with other present chemicals), which is related to the fact that relevant guidance documents in the ecotoxicological risk assessment process leave ample room for interpretation.Footnote 11 The dominance of this single-metric approach is so powerful that its narrow scope has become system-defining and entrenched in the scientific, political and legal formats, rendering effects not fitting this model largely illegible to these domains of enquiry.Footnote 12

In Section III, we show how environmental protections of aquatic environments are present in European law, but often receive superficial or secondary attention in practice. We argue that this is because in the EU legal system, important issues such as schemes for reducing pesticide quantities are neglected. Overall, we find that regulatory policy structurally deprioritises water legislation and water politics vis-à-vis other political and economic issues. This systematic ambiguity regarding the protection of aquatic ecosystem health in legal and political discourse has been documented as subsumed under heading of “anthropocentrism” in the chemical Anthropocene.Footnote 13

Finally, in Section IV, we reflect on the discrepancies between the regulations for aquatic contamination and the implementation of these policies in practice. Ecotoxicological assessments emphasise the importance of ensuring that no unacceptable harms come from chemical application, and yet the actual discrepancies between which outcomes are in fact deemed acceptable rarely gets fed back into the policy process.Footnote 14 We further discuss how the current deficient legal framework is situated in a broader socioeconomic system and can be understood as part and parcel of this system. While enforcement questions bear on the regulatory systems involved, analysing enforcement is outside the scope of this paper. When analysing these discrepancies, we also draw on prior theoretical insights from the literatures of science and technology studies and politics of science advice.Footnote 15

In addressing these questions through the case of glyphosate and its associated products, we enquire into how “compartmentalising” risk serves to underestimate the transversal actual hazards that chemicals catalyse in waterways for humans and other organisms. Compartmentalisation occurs both in the separation of risk assessment and management and in the separation of the active substance glyphosate from real-world blended chemicals. Here, we focus on the authorisation of the active substance on the European level and, to a lesser extent, on the authorisation of plant protection products (PPPs) at the EU Member State level – rather than on other aspects of pesticide politics, such as retail or application. Pesticide politics is complex. But the two-fold EU authorisation process is particularly complex and has been demonstrated as being determinative in making sense of other aspects of chemical regulation.Footnote 16

In this contribution, we specifically focus on the various reductionist modes of pesticide risk assessment that justify downstream authorisation. The compartmentalisation of risk assessments based primarily on in laboratorio data on a given isolated chemical versus the complicated relation of these to messy in situ field and epidemiological data leads to the perverse valuation of models of chemical toxicity over the actual effects that these chemicals have in interaction with other chemicals, other substrates such as water and the varying experiences of biological life. In situ (higher-tier) experiments, however, produce higher ranges of uncertainty regarding the absence of harm – even harms that are actually present. Paradoxically, by trying to make regulatory tests of chemicals more representative of reality, risk assessment tends towards permissiveness in terms of authorising harmful chemicals.

To reach these conclusions, we drew on document analysis, desk research and a non-systematic literature search (including, for instance, a web search for position statements on glyphosate and water by regulatory agencies at the EU level and in selected Member States – all major position statements and opinion pieces that contain mention of glyphosate and biodiversity). This article does not pretend to be a granular critique of the technicalities of the risk assessment procedure (ie comparing contrastive guidance documents), nor does it propose a cohesive plan to refashion chemical regulatory processes with respect to water. Instead, our findings offer key avenues for further research, pointing out for political scientists and legal scholars areas for investigating weaknesses at the intersection of pesticides and water regulation.

II. The presence of glyphosate in water and its impact on ecosystems

Narratives of how – even whether – pesticides impact (aquatic) ecosystems seem to be neatly aligned with different positions on the role of industrial agriculture.Footnote 17 This section explores the risks of glyphosate for aquatic ecosystems – chemical impacts on ecosystem functionality or biodiversity – highlighting specific controversies as debated in environmental science and policy.

Pesticides like herbicides (herbicides are here considered a subset of pesticides) applied to crops impact soil, agricultural irrigation channels and runoff.Footnote 18 Runoff from these applications has different impacts on varying types of aquatic environments, such as ground water, rivers, wetlands and reservoirs. Both direct and indirect runoff can affect water in proportion to the amount of chemicals applied, how focused they are sprayed on plants, the adhesives or adjuvants in the chemical and the size and ecological structure of the water system.

Europe is an outlier globally in terms of peak concentrations for glyphosate in waterbodies. In Europe, there are persistent but low concentrations of glyphosate. In many other global regions, peak concentrations sometimes reach up to 10,000 times the concentration of average EU levels.Footnote 19 While ecotoxicologists in Europe acknowledge that glyphosate exacerbates and compounds multiple environmental stressors and water quality issues,Footnote 20 they simultaneously fear that likely alternative replacement chemicals, which would make their way through prevailing chemical regulation frameworks, could be even more environmentally harmful – if agricultural production continues unchanged.Footnote 21 This suggests that plans to make EU glyphosate-free must also be accompanied by the larger challenge of reducing chemical inputs in agriculture in general; and that failing to address these issues in tandem may land regulators in the same tight spot they find themselves in with glyphosate, only next time with glyphosate’s successor.Footnote 22

Various statutes and laws in national and EU legislation protect water from chemical runoff, all of which have fundamental strengths and flaws. The central piece of legislation on water quality, with an ambitious schedule and a reporting system that has re-orientated water management approaches throughout Europe, is the EU Water Framework Directive (WFD). Its twin objectives stipulate that European waterbodies should be in good chemical and ecological condition. Pesticides (including herbicides such as glyphosate) can be found to violate these objectives in waterbodies either by exceeding environ mental quality standards (EQSs; chemical status) or by significantly impacting the ecology of a waterbody (ecological status). Notably, glyphosate is not among the substances of the EU WFD’s daughter directive on EQSs for surface waters 2008/105/EC, which sets limits and monitoring obligations for around forty-five specifically hazardous chemical substances (not only pesticides). As it is formally a EU directive that specifies certain substances rather than others, the decision-making process is highly political: if a Member State fails to limit only one of forty-five substances, then the whole regulation of the chemical status is regarded as failed for a specific monitoring period. In other words, to regulate a substance through this directive requires a high degree of consensus on the chemical’s danger to reach the threshold of regulation. Likewise, the directive is predominantly formulated to apply to large waterbodies and the chemicals found therein, which means that smaller streams common in agricultural landscapes are often excluded from river basin management plans. Despite the lack of systematic monitoring of glyphosate residues in water, evidence has emerged as to its presence in Europe. In its Report on Glyphosate, the European Food Safety Authority (EFSA) acknowledges that glyphosate and its metabolite aminomethylphosphonic acid (AMPA; which maintains the same properties of glyphosate but is more persistent) have been found in a number of countries above the parametric limits. Italy is a case in point, where a study by the Italian Higher Institute for Environmental Protection and Research (ISPRA) in the “National Report of Pesticides in Water” found that “[i]n surface waters, 274 points of monitoring (21.3% of the total) show glyphosate concentrations above the limits imposed to guarantee environmental quality standards”.Footnote 23

Similar to the political debate around glyphosate,Footnote 24 aspects of the scholarly debate within ecotoxicology have been extraordinarily heated regarding the extent to which glyphosate-containing products harm aquatic ecosystems.Footnote 25 In an unusually hostile academic exchange in the journal Ecological Applications, two groups of authors have accused each other of unscientific behaviour – claiming that Roundup® is either generally harmful or generally safe for amphibians. Contributors to this and subsequent debates have sought to disqualify the other’s research by pointing out the role of corporate or non-governmental organisation (NGO) funding influencing the neutrality of their assessments.Footnote 26 At the centre of the controversy were claims regarding Roundup®, the top-selling herbicide product containing glyphosate as its active compound, as well as the surfactant polyoxyethyleneamine (POEA) and its impact on lethality to tadpoles (with the claim being: “Amphibians Are Not Ready for Roundup®”).Footnote 27 Here, the discussion has focused on the so-called “inert” ingredients/additives that are part of commercial formulations of herbicides. To penetrate leaves and to stick to them rather than washing off, Monsanto (now Bayer) has insisted on the need for such additives.Footnote 28 Inert ingredients are typically trade secrets, and the academic discussion has focused on the core issue that the products used outside the laboratory and in the field are a combination of a highly scrutinised substance (glyphosate) and under-regulated additives that makes the product highly toxic to amphibians (eg which penetrate through tadpole gill cells). Critics see a pattern in the risk assessment systematically underestimating the harm of adjuvants.Footnote 29 Similar intra-scientific controversies have occurred related to a different herbicide, atrazine, where a similar drama unfolded with accusations of corporate sponsoring of “industrial product defence research” and eco-activist research.Footnote 30 While the glyphosate and atrazine cases may be the most notable discussions in the literature, in mainstream ecotoxicology building on field studies, it is increasingly clear that there are negative effects on aquatic biodiversity or freshwater ecosystem functions from pesticides more generally.Footnote 31

A non-systematic search demonstrates the range of ecological effects for which glyphosate has been implicated in the toxicology literature. Glyphosate’s direct toxic effects have been described as lethalFootnote 32 to affected organisms such as amphibians or pollywogs, or sub-lethalFootnote 33 but leading to dysergistic (negative synergy) impairment to affected organisms such as honeybees, spiders and lacewings.Footnote 34 As described by the German Federal Agency for Nature Protection (BfN) in their remarkable position paper on glyphosate,Footnote 35 the two main ways glyphosate can impact biodiversity are through: (1) direct toxic effects on non-target organisms; or (2) indirect effects on non-target organisms. Direct toxic effects on non-target organisms are further subdivided into lethal and sub-lethal effects. Because of its chemical structure, from a purely theoretical analysis, it is widely assumed – correctly or not – that there are no direct effects of glyphosate on insects. Most biologists indicate that glyphosate’s principal effects on insects result from harms to food webs that negatively impact the agricultural landscape and organisms. Thus, the German environmental ministry claims: “The use of broad spectrum herbicides such as glyphosate does not kill insects directly”.Footnote 36 The tricky part, however, is that the complicated indirect effects (as well as a range of conceptions of what counts as an indirect effect) actually do end up harming a variety of insects.Footnote 37 The complexity of these effects is exploited by various actors to give vastly contrastive interpretations about the scale of the problem and the chemical’s safety. The impact of glyphosate in water includes indirect harms to the insects and other lifeforms that inhabit it.

The most influential EU agency in this sphere is EFSA, which advises the Commission and has been at the centre of European glyphosate regulation through its risk assessment.Footnote 38 EFSA notes that glyphosate acts as a broad-spectrum herbicide against all plants that are not protected by a specific genetic modification. The active ingredient stops the synthesis of certain amino acids that are essential for plant growth, leading to plant death. As an individual substance, glyphosate has a relatively low (eg chronic) toxicity compared to the worst agrochemicals historically – such as DDT – and appears much less immediately toxic; here, most ecotoxicologists and regulatory agencies agree.

Yet, as debated as the dysergistic toxicity of glyphosate plus its adjuvants has been for EFSA, less recognised or accounted for in toxicity regulation has been glyphosate’s indirect effects on aquatic ecosystems. Because of the complexities of chemically dependent agricultural production systems and land use configurations impacting biodiversity, these often delayed or indirect processes have received less focus in chemical regulation. Agrochemical use is linked to reduced biodiversity through cascading ecosystem effects involving freshwater contamination, even if biodiversity loss may not be directly caused by it.Footnote 39 “Indirect effects” are usually described as the deterioration of plant and microbial life in agricultural landscapes; these effects are especially demonstrable on food webs. The influential 2019 Leopoldina report describes how, at the community level, herbicides doing damage to plants will have indirect food chain effects (glyphosate was explicitly named), and that these processes have not been adequately accounted for in regulatory approval procedures (which focus on individual populations instead).Footnote 40 Yet different disciplines and even different schools of thought within ecology disagree over the implications of “indirect” ecological effects. We designate “indirect effects” here to encompass the notion of indirect toxicological and ecological effects that can result from dysergistic amplification through other effluents and exposures stemming from industrialised agricultural production. Concretely, glyphosate enables and furthers the usage of vast monocultural landscapes (and hence, inter alia, limits crop rotation and locks in specific economics activities and food supply and land use arrangements). These indirect effects from use on production processes have knock-on effects that potentiate the actual direct biochemical risks of glyphosate and its adjuvants. As the most used herbicide worldwide (total historical use globally until 2016 amounts to 6.1 billion kilograms),Footnote 41 whatever glyphosate’s determined indirect effects, by virtue of the volume of use, these indirect effects will likely be more pronounced and varied. The paradox that glyphosate is relatively inexpensive and putatively efficacious for crop protection in the dominant high-input agrichemical industrial food production model may render regulators reluctant to directly confront the other costs of the chemical, such as the ecological ones.Footnote 42

Worldwide, glyphosate enables genetically modified (GM) plants to be bred to be glyphosate-resistant. In Europe, glyphosate is authorised for specific uses (in the context of GM crops being generally prohibited). In the case of Germany, for example, it is used mostly for stubble management (with uses such as siccation – the pre-harvest application of pesticides to quicken the crop-drying process – increasingly being outlawed), while in select countries glyphosate is also approved for aquatic or semi-aquatic use. Broad agreement among the regulators involved in the two authorisation procedures at the European and national levels exists that glyphosate and glyphosate-based products themselves do not constitute major problems for biodiversity in Europe according to the metrics of the prevailing risk assessment system.

The seeming consensus on the lack of direct biodiversity problems of glyphosate is surprising, as for some pesticides, such as neonicotinoids, achieving scientific consensus regarding clearly demonstrated biodiversity impacts has been swift and effective for establishing the case for regulatory action.Footnote 43 Yet for glyphosate, scientists and policymakers by and large have agreed that, for the purposes of the European authorisation processes, glyphosate should not be outlawed for ecological reasons. It should be noted, however, that the risk assessment system unnecessarily confines itself to single-substance analysis only, as discussed below. Agencies such as Germany’s BfN, for example, which are not directly involved in the authorisation system or risk assessment, have been much more critical of the biodiversity effects of glyphosate than the responsible regulatory agencies involved in the two-tier authorisation system, claiming that “the current state of science indicates that indirect effects of glyphosate or glyphosate-containing herbicides on non-target species in particular pose a high risk to biodiversity”.Footnote 44 Such statements contrast with industry assessments that argue that a ban on glyphosate is associated with increased environmental pressures from agriculture due to compensating by deploying more intensive agribusiness practices requiring higher volumes of potentially more toxic chemicals, leading to worse biodiversity outcomes.Footnote 45

Such outsider opinions to established regulatory systems circumvent entrenched risk assessment paradigms and criticise regulatory agencies for regulating only individual chemicals in isolation rather than the admixtures used in practice.Footnote 46 Likewise, cocktail effects and multiple stressors are at the same time observed as being understudiedFootnote 47 and are thought to be under-regulated, as certain substances are potentiated by others (eg atrazine and glyphosate amplifying each other’s toxicological affects).Footnote 48 One study looking at how sunlight can potentiate the toxicity of certain pesticides assaying cell micronuclei found pesticides, including glyphosate, to be twenty-fold more toxic when mixed, and the mixture became 100 times more toxic after light irradiation due to oxidative stress.Footnote 49 Prevailing environmental risk assessment methods are widely acknowledged to be deficient for accurately measuring the unintended cocktail effects of pesticides.Footnote 50 It is no simple matter, however, to resolve this issue: complications regarding risk assessments of pesticides are controversial and receive a high level of scrutiny.Footnote 51

In addition to the discrepancy of regulatory assessments focusing on single isolated chemicals and the cocktail mixtures of chemicals actually applied in situ are the problems of so-called “higher tiered” risk assessments. Higher-tiered issues coalesce around the deficiency of pesticide risk assessments based on models of predicted exposure concentration (PEC) in the environment as required within legal bounds of certain concentrations in order to be designated safe for non-target organisms in EU as well as US risk assessment. In this system, the regulatory acceptable concentration (RAC) is the cornerstone of the risk assessment process. This threshold has been problematised as a “controlled experimental tiered risk assessment approach, giving results that are difficult to extrapolate to a real-world situation”.Footnote 52 Reliance on ecotoxicity data from “laboratory and semifield (so-called mesocosm) studies”Footnote 53 alone is particularly problematic, as safety concentrations are established through “[s]tandard toxicity tests, i. e., tests performed with single chemicals and single species under laboratory conditions without additional stressors”.Footnote 54 A Pesticides Action Network (PAN) report notes the following: “Microcosm and mesocosm systems are widely used in pesticide approvals; their attractiveness can easily be explained because the standards for aquatic toxicity can be made less strict [emphasis added] in numerous ways compared to the lower tier studies. This is partly due to the system itself (clean water, no pollution, variety of organisms) and statistical methods applied but also because uncertainty factors are lowered or not used anymore in higher tier”.Footnote 55

Such toxicity analyses are a far cry from the other threshold, which operationalises “[s]afety factors (also called assessment factors) that account for uncertainties in the extrapolation to real ecosystems”.Footnote 56 This evident mismatch between results from field studiesFootnote 57 (showing that the “relationship between pesticide exposure and community composition is causal”) and experimental tests relevant for regulation excludes the key ingredient for regulations: actual outcomes rather than theoretical safety. Apart from underspecified protection goals, Schäffer et al argue that there is no “scientifically validated prediction framework” that combines “ecological context, landscape context, farmer behaviour” and other non-laboratory aspects needed to predict exposure and effects.Footnote 58 Instead, provisional authorisation solutions have been proposed (similar to suggestions to include post-monitoring of pesticide vigilance as guiding principles).

The relative problems with the tiered risk assessment system are less significant for unambiguously toxic pesticides where predicted exposure exceeds “safe concentrations”, but they are greater for pesticides where the gap between predicted and actual exposure widens. Agrochemicals that are less predictable in terms of their field toxicity can nonetheless be authorised “if the producer can show through further data that its environmental and human health impacts are acceptable”.Footnote 59 The virtue of tiered frameworks is that they allow for extending assessment to further ecological safety analysis encompassing more complex scenarios where “[h]igher tiers integrate processes and characteristics occurring in natural ecosystems, such as multi-species semi-field test systems in the EU, as well as reduction of exposure through mitigation measures in risk management”.Footnote 60 These aggregating assessments can usefully be fed back into reassessing risk at more core levels. Such analyses provide for water issues and ensuing biodiversity harms becoming more legible and weighty in risk assessments than they otherwise might.

Schäffer et al point out that the issue with this framework is that by default “authorization is given as long as the predicted exposure concentration (PEC) does not exceed the predicted no-effect concentration identified by single tiers, multiplied by the respective safety factor. Only substances that fail all tiers are not authorized”.Footnote 61 The most likely result of the safety threshold system is a no-effect judgment, because the regulatory edifice is built on laboratory toxicity testing and the format of tiered studies with little initial input from field studies. Such systematic underestimations (or type II biases) can lead to “inaccurate predictions of both exposure and effects in tiered system”.Footnote 62 This critique by ecotoxicologists of the existing risk assessment framework is shared by other scientists critical of glyphosate’s ecological harms.Footnote 63 Likewise, the German Federal Environmental Agency (Umweltbundesamt, UBA) criticises tiered risk assessment as often counterproductive for ecosystems, unnecessarily expensive and too difficult to communicate to the public.Footnote 64 The recent Leopoldina report entitled “The Silent Spring” also delineates problematic details of the tiered risk assessment as practised today, such as deliberately not double-checking pesticide effects that have been vetted at other levels.Footnote 65 The very few experts on these issues are in consensus: “[C]ritical revisions of related pesticide regulations and effective mitigation measures are urgently needed to substantially reduce the environmental risks arising from agricultural insecticide use”.Footnote 66

In recent months, the pan-European politicisation of glyphosate as a problematic chemical has brought the entire risk assessment framework under serious scrutiny.Footnote 67 Nonetheless, possibly because there are only a handful of people who understand the intricacies of the issues at hand, or due to a lack of political interest groups advocating for the rights of aquatic ecosystems, the specific issue of harm to aquatic ecosystems as a result of omissions in the risk assessment framework has not been made.

Defenders of the status quo risk assessment procedures note that regulatory tools, especially the guidance recommendations used by EFSA, undergo continuous development, and already include indirect effects (albeit in the limited sense described above). New test and reference organisms can be specified and extended, and as climate conditions continue to change, updates to the pre-existing models can occur. Similarly, different models to calculate PECs are being constructed, with much effort being spent to coordinate such approaches across scientific and regulatory institutions. Even with these updates and addenda, however, the tiered framework does not consider aggregate pressure, and it uses laboratory tests as approximations of real-world effects. For these reasons, the tiering system prevents ecosystem effects from being material in decision-making by isolating pertinent cross-effect observations through unnecessarily complex regulatory stringencies that are inscrutable to most involved parties. Glyphosate in its pure form (which occurs only in the laboratory) is paradoxically then assessed as low toxicity and perfectly “adapted” for regulatory systems unwilling or unable to capture real-world indirect effects – especially in aquatic systems.

III. Much more than glyphosate (or how risk assessment marginalises the assessment of environmental risk)

Bernhard Url, EFSA’s executive director, responded in a recent interview with news media Euractiv that he views the conflation of science and politics in the glyphosate saga as “unreasonable”:

Glyphosate has become the symbol of much more: it’s no longer about a herbicide, but about the way we do agriculture in Europe, the loss of insects and pollinators, the globalisation of trade, biodiversity …

This can only be dealt with proper communication but also with a reasonable distinction between what is policy and what is science. To give you an example, people were surprised when they found glyphosate in the urine of their children. But this is a policy question: if we use glyphosate, we will find it, because analytical methods are so sensitive nowadays that basically everything can be found.

If you don’t want to find traces of glyphosate in beer or in spaghetti, then you have to talk about its use and not about its safety. All the traces have been found present no safety concerns and all other regulators in the world have said it is safe if it is used properly. But it does not mean that it has to be used.

What I hope for the next glyphosate reauthorisation is that there’s also an assessment on what would it mean, if glyphosate or herbicides are not used anymore for biodiversity, water, farmers income, food prices, availability of foods and so on. This was what we missed in the previous glyphosate discussion.Footnote 68

Url is correct in assessing that glyphosate has ballooned into a banner representing a host of structural issues. Arguably, the glyphosate case is not just a symbol of “much more”, but an epiphenomenon of “much more”; it reflects that current risk regulation compartmentalises risk diagnoses in such a way that critical questions are eluded or “back-staged”.Footnote 69 In fact, glyphosate is always excessive in its significance; there is no such a thing as raw glyphosate in its actual use. Glyphosate as actually applied in any of its over 700 commercial formulations used in the physical environment is blended with an array of compounds (such as adjuvants and co-formulants) and typically receives little scrutiny by domestic regulators, as mentioned above.Footnote 70 The chemical imaginary of glyphosate as a pure product, divorced from its adjuvants and co-formulants, does not exist, and, as has been argued, should not be treated as if it did for regulatory purposes. Yet, risk assessments code current law to individually assessed chemicals without assessing them in the light of real-world chemistry, in which they are blended together. Treating chemicals separately from a regulatory perspective, instead of informing regulation by the science of chemistry and chemical interactions, is an expedient legal artifice. At this point, it is worth recalling that the European legal framework establishes a two-track system for the approval of pesticides: the active substance, in this case glyphosate, is assessed and approved at the EU level, whereas the different formulations are approved at the level of individual Member States and further circulated in the internal markets through mutual recognition.Footnote 71

The EU Parliament, in its 2018 Report on the Union’s authorisation procedure for pesticides, has noted the difficulties of approval procedures at the national level as follows: “… understaffing and/or underfunding may result in over-reliance on the assessment conducted for the approval of the active substances in the context of decisions for plant protection products”.Footnote 72 Assessing the numerous pesticide products containing glyphosate with the same degree of granularity as for active substances (~700 commercial formulations versus a single active substance) could in fact prove to be a daunting task and disrupt industrial agriculture. In this context, scholars have criticised the fact that “[p]esticide co-formulants considered to be inert are generally exempt from the requirement for establishing a tolerance limit, and for this reason, end-use commercial pesticide formulations escape from being subjected to chronic toxicity testing, despite the fact that the vast majority that have been tested are actually more toxic than the declared active ingredients alone”.Footnote 73

In this respect, it warrants note that in the process for the 2017 re-authorisation of glyphosate, the EU Commission took the unprecedented decision to propose a ban on one of the main co-formulants used in glyphosate-based pesticides: POEA. Yet, POEA continues to be used in other pesticides (without glyphosate) and can be bought in the market “as a separate adjuvant mixture (product name Regain, authorization 9300433) to mix with a glyphosate formulation in the spray tank”.Footnote 74 The fact that a specific co-formulant found to be dangerous at the EU level continues to be used in non-glyphosate-based pesticides is further evidence of how formulations containing toxic “ingredients” could more easily go undetected at the domestic level.

Against this background, one can agree with Dr Url in emphasising the importance of distinguishing “what is policy and what is science”. The choice to assess only the active substance (glyphosate) at the EU level cannot be separated from political choices. More generally, risk assessment is a practice that is deeply embedded in law. As one participant to an EFSA Management Board meeting said: “[I]t should be emphasized also that it is legally-binding evidence-based risk assessment [that EFSA is following] … that EFSA, by its mandate, will not take into consideration all available information for legal reasons”.Footnote 75 The difficulty with agencies such as EFSA making risk assessments on chemicals such as glyphosate is that often such assessments become interpreted by the general public, as well as scientists, as scientific findings or official consensus rather than as hybrid practices rooted in science as well as in policy processes.Footnote 76

The decision to structure risk assessment around the identification and measurement of certain risks by a single isolated substance is another notable political choice. The main health lens applied so far, for example, has been on carcinogenic risk. This is arguably because the EU Regulation establishes that carcinogenicity is a cut-off criterion to decide when a substance should be banned.Footnote 77 Much less attention is paid, however, to environmental risks, and by extension the downstream environmental health threats, despite this regulation equally protecting the environment.Footnote 78 The case of water is a representative example. A report by the NGO Pesticide Action Network alleges several instances of weakened protective standards throughout the EU regulatory framework through controversial risk assessment methodologies, highlighting specifically the treatment of potentially harmful metabolites in ground water as “non-relevant”.Footnote 79 Generally, it is the description of data requirements in the sections on ecotoxicology and environmental fate and behaviour that is determinative.

When the risk to aquatic environments is considered, the EFSA report lacks clarity. The report’s conclusions mention that “[g]lyphosate and AMPA have been detected in Europe above the parametric limit of 0.1 μg/L in a number of instances. Detailed groundwater monitoring studies demonstrating that glyphosate exceeded the limit of 0.1 μg/L were available from Italy, Germany, the Netherlands, Sweden, France and Spain”. The assessors explain that these contaminations may be due to “misuse” of the product and that drinking water can be treated using chlorinating procedures.Footnote 80 But even if “misuse” would be the primary case of the violation of parametric limits, should such “misuse” not be considered as part of the embodied risk?

Interestingly, in different contexts, other EU legal representatives consider the use or misuse of potentially toxic products as part of risk and hence of “risk assessment”. This has been an issue in the Hormones dispute between the EU and the USA. The World Trade Organization (WTO) Appellate Body has concluded that “abuse” or “misuse” of potentially toxic products can be considered as part of risk assessment.Footnote 81 In this context, the EU has tried to defend its precautionary policies (eg vis-à-vis the use of hormones in food chains for growth-promotion purposes), which, to be fully realised, may need a more holistic conceptualisation of risk assessment. It could be argued that by considering real harms as products of misuse rather than design or inaccurate modelling, both companies and regulatory agencies, across industries, effectively externalise actual risk.Footnote 82

As mentioned above, another major limit to the type of risk assessment used for regulatory purposes is that it does not examine chemical mixtures and their synergistic (dysergistic) impacts.Footnote 83 Yet, the aquatic environment is exposed to these mixtures together rather than single substances sequentially. Risk assessment practices also fail to retrospectively look at the data produced through environmental monitoring that examines the manifold ways through which chemicals are transformed by the substrate through which they travel and react.Footnote 84 In this respect, the European Court of Auditors has issued a Special Report that criticises – among others – the deficient status of the environmental monitoring of pesticides.Footnote 85

To fully understand how environmental risk is further side-lined in contemporary practices of risk assessment, we need to take a step back and look at how pesticides are regulated in Europe through Regulation 1107/2009 concerning the placing of PPPs on the market and Directive 2009/128/EC on the sustainable use of pesticides.Footnote 86 The European legal framework can be seen as a dual system. As briefly mentioned above, on the one hand, active substances (such as glyphosate) are to be assessed and approved by EU institutions; on the other hand, the commercial products to be placed on the market (including co-formulants) are approved by national authorities and can further circulate in Europe by virtue of mutual recognition. Next to the authorisation process, this dual system is reproduced in how issues of sustainability are addressed. In this context, Directive 2009/128, which has the general goal of achieving “a sustainable use of pesticides by reducing the risks and impacts [not necessarily the amount] of pesticide [like glyphosate] use on human health and the environment and promoting the use of integrated pest management and of alternative approaches or techniques such as non-chemical alternatives to pesticides” (see Article 1, Directive 2009/128), establishes only few specific obligations on Member States (eg prohibition of aerial spraying, per Article 9). For the rest, it delegates to the Member States the enactment of specific measures through the adoption of National Action Plans (NAPs; see Article 4, Directive 2009/128). As a result, the question of whether the use of pesticides like RoundUp® is reduced and/or used more sustainably depends on the measures adopted by individual Member States. In this context, it is worth mentioning that reduction targets are absent from virtually all NAPs (the main exception being France).Footnote 87

NAPs have been widely criticised by environmental groups. Looking at the Directive itself, it becomes clear that, at the heart of the EU Directive, a vague political compromise ends up eliding concrete policy objectives: the Directive leaves slack in interpreting whether the absolute quantities of pesticides should be reduced, or “merely” the associated risk of pesticide use: “… risk reduction or use targets shall be set at times and targets for the restriction of use, in particular where the restriction of use is an appropriate instrument to achieve risk reduction in relation to the priority topics referred to in Article 15(2)(c)”. According to EU law, NAPs require stakeholder participation and, in principle, the possibility to publicly scrutinise pesticide-related plans. The inadequacy of these plans has been nowhere as clear as in Germany, where, in 2011, stakeholders that aligned with environmental interests left the NAP in protest (surprisingly, this included the commercial German association of energy and water industries, BDEW). NGOs report that a lack of transparency and a dubious selection of indicators were the reasons for their withdrawal from the NAP, noting that the ministry-led process would – in the end – strengthen the current system of agricultural use of chemical PPPs rather than reduce dependency on agrochemicals.Footnote 88

In this way, the NAPs demonstrate power imbalances in participatory processes of environmental entrenched interests that contradict those of protectors of aquatic ecosystem health, and instead do not address issues such as the excessive use of glyphosate. In this context, PAN criticises the Dutch NAP as an example of private actors drawing up guidelines for agricultural application without broad stakeholder participation.Footnote 89 The binding nature of the NAPs varies from country to country, but is extremely weak overall. In Denmark, for example, the ban of chemical pesticides in certain areas for urban drinking water falls into abstraction due to the lack of concretisation in determining an “overall pesticide load indicator”. In addition to countless unambitious declarations of intent, as in Germany or Poland, there are also processes of silent adoption of binding targets, as in the Netherlands in terms of plant protection plans, where plant protection monitors have been suddenly introduced.

In Germany, the coalition government announced a national insect protection programme that calls for the reduction of pesticides, especially glyphosate, with a specific stipulation of phasing out the herbicide completely by 2023.Footnote 90 Polls in Germany suggested that more than seven out of ten people favour a ban on the substance,Footnote 91 which was cited to be a factor in the agreement of both agricultural and environmental ministries to this phase-out.Footnote 92 But Germany’s responsible agency BVL authorised its use until 15 December 2020 for another year, without any changes to application rules, or even regulation of private usage, or any type of minimisation/reduction strategy.Footnote 93 And the Glyphosate Renewal Group – a group of agrochemical producers – has already submitted applications for renewal of the substance after 2023.Footnote 94 The battle around glyphosate was the catalyst for the inception of the PEST Committee of the European Parliament in 2018.Footnote 95

Regrettably, beyond the obligation of developing NAPs, the question of how Member States can and should assess the risks of pesticides remains elusive. As mentioned above, the Directive itself remains ambiguous as to the necessity (if not the urgency) of addressing the absolute quantities of pesticides discharged in the environment. In the Anthropocene, quantity is crucial to safety. But in a market-driven society, decreasing the quantity of agricultural inputs results in a net loss of income for the supplying manufactures. In this sense, it is remarkable how the regulatory framework marginalises questions of quantity. The fact that glyphosate is the most widely used active substance in pesticides worldwide is masterfully eclipsed by elusive NAPs. The words of Dr Url, which dissociate safety from use, may then reflect the resistance of a regulatory system that tends to privilege the protection of capital over the protection of the environment. At the very least, methodological assumptions baked into the system bias risk assessments towards the assumption of non-toxicity for all of the configurations of toxicity that are not known.

The case of water is exemplary in displaying how this disassociation seems to underpin the current EU legal framework, which marginalises sound appraisal and management of environmental risks. On the one hand, the legal framework recognises the importance of water; for example, Paragraph 15 of the Preamble of Directive 2009/128 explicitly refers to the fact that the “aquatic environment is especially sensitive to pesticides”, and that “[i]t is … necessary for particular attention to be paid to avoiding pollution of surface water and groundwater by taking appropriate measures, such as the establishment of buffer and safeguard zones or planting hedges along surface waters to reduce exposure of waterbodies to spray drift, drain flow and run-off”. Moreover, according to Article 11, Member States shall establish specific measures to protect the aquatic environment and drinking water. On the other hand, the legal framework fails to establish the institutions to systematically collect information and monitor the effects of pesticides on aquatic environments and to protect the aquatic environment in effective ways.Footnote 96 Numerous reasons contribute to the undercutting of these principles, and critical NGOs admonish that crucial information is overlooked, hidden in guidance documents or circumvented through undetected non-compliance with such documents, with a further issue being the political process surrounding the nomination of experts to relevant committees.Footnote 97

In short, the legal architecture by which most attention is directed towards assessing the carcinogenic risk of the active substance diverts attention away from other important risks deserving of consideration, such as the risk to surface water and ground water. Despite the acknowledgment in the legal text that the (aquatic) environment should be protected (eg Article 4 Regulation 1107/2009 and Paragraph 15 of the Preamble of Directive 2009/128), the legal framework lacks strong and well-coordinated provisions to address this issue. This is not only evidenced by the weak NAPs of individual Member States, but also by the proven pollution of watercourses by glyphosate and the absence of (planned) corrective measures.Footnote 98 Regrettably, the concrete rules relating to the protection of surface and ground waters remain aspirational at best.

IV. Discussion

Let us return once again to the words of Bernd Url when he writes: “What I hope for the next glyphosate reauthorisation is that there’s also an assessment on what would it mean, if glyphosate or herbicides are not used anymore for biodiversity, water, farmers [sic] income, food prices, availability of foods and so on”.Footnote 99 This statement invites consideration of broader questions; yet, it conflates a number of key socio-political and scientific questions and, above all, implicitly forecloses the discussion of a plurality of scenarios. First, the statement suggests that the only choice we have is glyphosate/herbicide versus a fully pesticide-free world with the assumed knock-on hardships that would ensure. But, what about a significant reduction of the use of pesticides, or the adoption of biocompatible agrichemicals? Harm reduction in pesticide use is sometimes hyperbolically taken as an extreme abolitionism, rather than an admission that there is both a problem of chemical overuse in food production (with the documented consequences) and that realistic steps can be taken now to reduce the harms. The current legal system, with its split between a single-substance authorisation system and weak NAPs, seems oblivious to the total amount of pesticides used. Given the above analysis regarding the negative effects of glyphosate (and pesticides more generally) on the environment, it is striking that legally so little is done to reduce the total quantities of pesticides used in agriculture. It seems as if prevailing regulation has proved too blunt an instrument to deal with the incremental reductions necessary that would effect immediate improvement in health, ecological effects and ground water, without substantially upsetting prevailing high-input agricultural practices. Indeed, this gap in the regulatory system may also be seen as halting innovation and providing perverse incentives to firms. This structural gap has also been identified as a weakness of the EU legal framework by the recent report of the European Court of Auditors and as a major obstacle for “reducing the risks of PPP use”.Footnote 100 One hopes that the new resolve by the EU to adopt pesticide reduction targets, matured within the context of the New Green Deal, will be followed by concrete and resolute action.Footnote 101

Second, viewing the legal system as a site of knowledge production permits enquiring into the focus on risk assessment and the serious limits of such assessments as currently practiced for the authorisation of active substances regarding what knowledge is considered relevant in the regulatory process. Crucially, by focusing on the carcinogenic risk of the isolated substances to the exclusion of other demarcating lines or factors, knowledge on the effects of real-world chemical mixtures gets side-lined, as well as the effects of chemical cocktails on aquatic environments and life dwelling in affected habitats. Marginalising the effects of chemicals on non-human organism populations is the current default, but there is no inevitability that it must have become so, nor for it to continue. One may ask, then, whether the current configuration of risk assessment practices constitutes a particular manifestation of a “hegemonic principle of selectivity”.Footnote 102 When we engage uncritically with the question Url poses, we risk being oblivious of key scientific insights as well as socio-political questions. Url’s statement may also eclipse another larger question: is the current risk assessment preventing us from engaging in an open and much-needed conversation around which types of agricultural practices are desirable for the Anthropocene era?Footnote 103

Political, sociocultural and most of all economic entrenchment of agrochemicals make it very hard to regulate against them. Once introduced for crop protection as modern and effective, other methods become negatively valanced as primitive or archaic, even when they are also (or even more) effective (with potentially fewer side effects). The status quo bias in favour of supporting existing chemical use requires re-examining the entire infrastructure that led to such defaults, including the path dependency of approving given chemicals such as glyphosate.

Rather than ignoring or avoiding confrontation with the messy business of risk regulation by assessing the “easiest” and most “contained” models, making interdisciplinary sense of the sheer number of interactions and impacts chemical mixtures have as they react with their chemical and biological environments of application should be the actual matter of concern for risk regulation, however challenging it may be in practice.

Part of the weakness of social and political power in determining top-down whether or not a given population chooses the risks of such exposures emerges from the “divide and conquer” public relations of chemical manufacturers.Footnote 104 In many instances of agrochemical risk regulation and its framing by agrochemical companies, farmers and consumers are pitted against each other, when in fact farmers are normally much more exposed than those who eventually consume their products.Footnote 105 Paradoxically, farmers lobbying against their own health interests and for the status quo of the extensive inputs they depend on from agrochemical manufacturers means that entrenchment of harmful pesticides is often enacted by frontline proxies like farmers, who are most likely to suffer the health consequences. The reasons for farmers viewing pesticide regulations as threats to their successful harvests, rather than aiming at protecting their health and offering them effective alternatives,Footnote 106 is a complex and motivated historyFootnote 107 that is beyond the scope of this paper. It is evident, nonetheless, that taking seriously the intersectional issues of soil fertility, waterway health and human well-being requires a wholesale restructuring of the rules of agriculture to prevent an artificially input-driven race to the bottom.Footnote 108

There is also no reason to ignore important known information regarding the effects of chemicals on any sort of organism population or life system. The intricacies of the scientific findings on these topics call for creating enough regulatory space to assess and assimilate new data as they become known and to update regulation in more or less real time to encompass and encourage data that might require rearranging risk assessments and their accompanying policies. Wagner has suggested that one way to address the “toxics data gap” is to force chemical manufacturers to compete against each other in terms of risk reporting requirements, which would in turn “reposition” the role of regulatory agencies to harness the “expertise, information, and energies of manufacturers of safer products eager to put their competitors’ more hazardous products out of business” to benefit those companies that would gain through marketing safer products.Footnote 109 A similar approach has been instituted in the United Nations Global Compact (UNGC), which rewards companies with social license for their environmental and social reporting transparency. This voluntary mechanism creates the positive externality of data baselines for industries, even when only a few rival manufacturers choose to be transparent, as those participating companies set the bar for the rest of the industry. While the UNGC is not without its problems, this facet at least seems to answer Wagner’s call for creating a “market competition between rival firms to produce relevant information about the toxicity of certain chemical products on the market”.Footnote 110

True, reconfiguring risk regulation to take into account the full spectrum of environmental and human health harms will likely substantially reprioritise certain low-externality farming methods over the known harms of industrial agriculture. However, such disruptive regulation can also provide new economic niches for techniques and environmentally integrated companies working in regenerative agriculture.Footnote 111 More publicly and environmentally orientated risk regulations do not condemn the economics of farming, but perhaps change the players. Ecologies of innovation stipulate that companies and social creativity do not occur in isolation, but rather in ecosystems with other stimulating and constraining factors that uniquely establish niches to develop new technologies or services – which always interface with and are enabled by the state, whether consciously or not.Footnote 112 Disruptive regulation for the public’s benefit can restore commons, help farmers move away from soil-depleting agricultural practices fed by monopolised commodity chains, offer consumers more choice and empower ecologically focused companies previously at a disadvantage under previous chemical regimes.

Without a firm commitment to reducing overall pesticide use, however, such policies can be complicated by the tensions that regulatory agencies face due to not wanting to ban chemicals such as glyphosate because such a vacuum might result in new replacement chemicals that are even more dangerous than existing ones. An example of this, premised on the inevitability of harmful synthetic chemicals as a part of everyday life, is the film The Devil We Know, which takes its name from DuPont’s fifty-year cover-up of the fact that the group of chemicals (per- and poly-fluoroalkyl substances classified as “C8”) that make Teflon® and other perfluorooctanoic acid (PFOA) and perfluorinated alkylated substance (PFA) products cause birth defects, based on previously secret DuPont and 3M documents.Footnote 113 Although DuPont was aware of this fact decades before independent researchers finally indicted these chemicals,Footnote 114 DuPont management resisted replacing it, claiming “C8 is the devil we know”, whereas a new chemical (“the devil we don’t know”) might even be more dangerous.Footnote 115 Certainly, this argument has been made strenuously against banning glyphosate.Footnote 116 But such perhaps deserved fears that if we dispose of current risky chemicals then their replacements could present even greater risks is not only held by chemical manufactures, but also by regulatory bodies. Of course, such logic is premised on the inevitability of continued levels of chemical inputs, rather than scrutinising sceptically the perceived need for their continuance, especially according to business as usual.

Government agencies and regulators, however, do often fall into such frames of inevitability, buying into the actuality rather than the construction of dilemmas of regulating dangerous substances. Such framing is likely influenced by industry and the well-trodden revolving door between government regulation agencies, which are frequently accused of pro-industry thinking at the disservice of environmental protection.Footnote 117 Regulators’ perceptions, however unfounded, often collapse into a sense of being trapped, backed into a corner, where they cannot take decisive precautionary action, as if the arrangement of profits and shareholders for corporations, together with industry capture of regulatory agencies, precludes them from autonomous action going against the grain. While such outlooks are understandable, we need to move our regulatory institutions out of the realm of resigned determinism and animate them to define themselves as agencies creating coherent policies protecting the public interest. Right now, only a very thin veneer separates regulatory agencies from industry,Footnote 118 without meaningful circuit breakers that alert if a problem occurs. The cooperative model of industry with government has its limits, and at least some agencies need to be adversarial to industry, as Wagner suggests. For any system to achieve resilience, redundancy, slack and flexibility are required.Footnote 119 We need this in our institutions as well, with multiple back-ups in case one agency fails, using precaution and updating policies according to new findings from the field.

Finally, the asymmetry between the economic priorities for chemical manufacturers and farmers bound up in high-input agriculture overshadowing other concerns continues to haunt rational risk regulation and policymaking. Property rights as they have been distributed are framed as sacrosanct, while human rights and biodiversity rights, or rights against ecocide, are framed as aspirational, not yet configured into the balance in cost–benefit analyses. The long-term impact of such short-term thinking requires coordination to rationally reassess this dilemma.

V. Conclusion

The interactions between pesticides and water and the theoretical, modelled or otherwise a priori predictions reach their asymptote of explanatory power in the messy world of in situ application. This contribution discussed less the nitty-gritty of the biodiversity impact from a natural science perspective, and instead analysed the discourse and regulatory means surrounding the measurement and assessment of these impacts.

Regulatory bodies have historically been simultaneously very concerned with and very lax regarding chemical pollution in water. We documented that while existing EU laws could be marshalled for strong protection of aquatic environments – even when thresholds are surpassed – little is done to either post facto make amends or preventatively take measures to ensure that such limits will not be breached in the future.

Risk assessment will play a crucial role in the 2022 EFSA decision to deny or renew the continued use of glyphosate in the EU. Especially in light of the – in our opinion – overly dominant focus on whether the chemical is carcinogenic,Footnote 120 we have sought to show the necessity to expand such decisions in order to account for other pertinent factors, such as admixture effects on wildlife and fresh water. Such as an expansion would align with the target of enhancing “policy coherence for sustainable development” called for in Sustainable Development Goal 17.4. It would be a mistake, however, to take an “innocent until proven guilty” approach with regards to harms, especially in light of the lack of well-established monitoring mechanisms. Because of the insurmountable lag as science catches up with reality, overweighting “evidence-based” policy that requires watertight evidence before limiting the default approval of known problematic pesticides promotes a laissez-faire approach to regulating human and environmental health and creates a smokescreen for not addressing deep-rooted agri-cultural problems.Footnote 121 At best, the glyphosate case presents the opportunity to create a comprehensive chemical framework in the EU focused on precaution rather than adding more ad hoc and insulated evaluations (inviting their own problems)Footnote 122 incrementally tinkering with a process deserving an organised overhaul.

In this context, it is worth mentioning the questionable symmetry that corporate-funded researchers assume between their private profit-seeking corporate funding versus researchers funded by NGOs with missions to protect public health and the environment. This parallel assumes comparable goal-directedness. Yet, should an industry-funded researcher be influenced by their funding source, the tendency would be to underreport the actual harms of a substance, leading to potentially substantial health harms; should an environmental or health NGO-funded researcher be influenced by their funding source, their tendency would be to err on the side of precaution, creating a buffer between possible public health and environmental harms. For the latter, over-precaution would hurt the profits of a given private corporation and hinder farmers locked into industrial agriculture, but would favour reduction of material, physical and distributed harms over a larger group of stakeholders (often with consequent health harms skewing towards impacting those most economically and otherwise discriminated against in a given society). From a normative perspective, some funding effects may be less desirable than others. The above does not account for other forms of asymmetry, including the vastly unequal amount of industry funding aimed at proving the salience and safety of their products, which is orders of magnitude larger than NGO and state research funding investigating the safety of chemicals.

102 The term “hegemonic principle of selectivity” has been used by R Wolff, “Efficiency: Whose Efficiency” (2002) 16(3) Post-Autistic Economics Review 1. Discussing the concept of efficiency in economic analysis, the author writes, “Usually, one principle of selectivity reigns hegemonic: one set of selected effects is deemed ‘important’ and worth counting while others are marginalized or ignored altogether”.

103 It should be noted that both the UN Special Rapporteur on the right to food and the UN Special Rapporteur on the implications for human rights of the environmentally sound management and disposal of hazardous substances and wastes, in noting the adverse impact of pesticides on human rights, agree that it is necessary to address the questions of sustainable agricultural practices. In their 2017 Report, they write: “It is time to overturn the myth that pesticides are necessary to feed the world and create a global process to transition toward safer and healthier food and agricultural production”.
