City-Level Law and Action for Climate-Resilient Development in Southern Africa

Abstract This article studies eight cities in four countries in the southern African region (Namibia, Zimbabwe, South Africa, and Botswana) to explore whether and how local governing authority has been channelled towards local climate-resilient development. The authors undertook a desk-based identification and review of available primary and secondary legal sources and normative documents while also drawing on scientific papers and policy documents for statistics and information about urbanization, climate change, politics, and governance in the selected countries. The analysis is interested in the law but is not strictly of a legal nature in the sense that the authors did not aim for a critical analysis of the regulatory detail in the relevant legal instruments. Instead, the article provides an evaluation of the political, de facto choices made by selected local governments as to how and to what extent to utilize their governing authority (legislative and executive) towards climate-resilient development. The authors explore if and how local government powers in the four southern African countries are currently leveraged for local climate action, and comment on the possible reasons for the status quo by comparing the four jurisdictions.

Rapid urbanization in Africa and the impacts of global climate change on the continent's cities affect livelihoods, economies, and development trajectories. 1Research on the extent of this is proliferating.Economists, geographers, planners, climate scientists, environmentalists, and financiers are now shifting their focus to the African context in studies that have long been focused on the global north. 2 Collectively, these experts are interested in questions of population growth, urban and climate migration, land-use planning, resource exploitation, technological innovation, water scarcity, environmental disasters, biodiversity loss and deforestation, energy governance, mobility, public health, and unpredictable impacts on agriculture (food security).They are further interested in the state of investment, finance, and economic growth against the backdrop of pervasive poverty, marginalization, a history of colonization, and the desperate need on the continent for long-term just transitions. 3ith the exception of legal scholars analyzing decentralization in a selection of African countries 4 and others reflecting on specific developments in national climate change law regimes, 5 very few (if any) legal scholars have contributed to the discourse on cities and decentralized climate action in southern Africa. 6ee, e.In this article we study eight cities in four countries in this region 7 to explore whether and how local governing authority has been channelled towards local climate-resilient development. 8We do so through the prism of (i) the general interest in the rise of cities as global climate change actors 9 and as a fast-emerging force in international (climate change) law, 10 as well as (ii) the functions and governing authority of subnational governments in the countries under study.
In terms of the research method, we undertook a desk-based identification and review of available primary and secondary legal sources and normative documents, while also drawing on scientific papers and policy documents for statistics and information about urbanization, climate change, politics, and governance in the selected countries.The present analysis pertains to the law but does not intend to provide an exact legal evaluation, as we do not seek to conduct a scrutinizing examination of the regulatory minutiae contained in the legal instruments. 11The analysis is interested in the law but is not a strictly legal one in the sense that we do not aim for a critical analysis of the regulatory detail in the relevant legal instruments.It is rather an evaluation of the political, de facto choices made by the selected local governments as to how and to what extent to utilize their governing authority (legislative and executive) towards climate-resilient development. 12We explore if and how local government powers in the four countries are currently leveraged for local climate action, and comment on the possible reasons for the status quo by comparing the four jurisdictions.
The first part of the article (Section 2) reflects on the rise of cities as global climate change actors and what this suggests in more tangible terms for cities in southern Africa generally.Section 3 describes local (urban) climate governance and some of its typological manifestations.The discussion then turns to the functional responsibilities and the governing authority of local government in the four countries (Section 4).Thereafter attention shifts to the local impacts of climate change and a functional 7 comparative analysis of city-level action in the eight cities (Section 5).The article concludes with what the research suggests on the extent to which local law, policy, projects, and political choices in these cities gravitate towards local (urban) climate governance.We also reflect briefly on the research that remains to be done.

Global urban governance offers a conceptual framework for trying to understand the complexity in multilevel global governance structures and the fit therein of subnational authorities. 13The globalization of urban governance also presupposes some kind of standard for local government practice (operations, institutional design, municipal institutions, rules and policies generated by local authorities, etc.). 14The discourse on the globalization of urban governance has developed predominantly around countries, cities, city networks, and city-centred activities that are very much rooted in the cultural, social, economic, and political contexts of the global north. 15Despite this, the discussion remains highly relevant and appropriate.For instance, city leadership has been recognized as crucial in the response to contemporary global challenges, as demonstrated by the global-local reactions to the COVID-19 pandemic and its interconnection with international urban migration. 16Further, quasi-localized policy responses have increasingly proven effective in addressing global governance issues. 17his is partly because city governments are willing to push the boundaries of their competence and seek to take a leading role by meeting internationally agreed standards, thereby addressing some of the great issues of our time such as migration, inequality, the violation of human rights, and climate change. 18We know that cities possess a unique advantage in addressing global issues as a result of their close proximity to their constituents and direct exposure to the challenges arising from such issues.Ignoring such challenges is not a luxury that cities can afford, as they may have the potential to affect local realities and communities. 19n the context of climate change, the sentiment is that cities may be more democratically legitimate, and have unique capabilities in responding to the causes and effects of climate changeowing in part to subnational legislative and regulatory capacity vis-à-vis central governments. 20Particularly relevant for this article are local-scale climate actions, which provide an opportunity for local stakeholders, experts and authorities to identify and respond with targeted solutions. 21he above said, cities in southern Africa arguably do not neatly satisfy many of the assumptions22 that underlie the prevailing understanding of why and how cities have become respected global governance actors.23Southern Africa's peculiarity arises from its historical and developmental trajectories that continue to have an impact on recent legal reform processes. 24It is further fuelled by the recency of constitutional transitions at national level, 25 as well as what appears to be a tendency to effectively centralize rather than decentralize governing power,26 partly in response to 'a deeper underlying fear that cities will in due course breed political opposition'. 27n contrast with the city context and notable local climate governance initiatives in other parts of the world, 28 many cities in southern Africa are characterized 29 by widespread informality (housing, trade, labour, etc.), urban poverty, violent protests, high levels of inequality, low levels of social cohesion, local planning instruments designed to work for predictable futures, weak(er) governance and infrastructural assets, huge finance deficits, large-scale skill shortages, economic migration, a state of being locked in by constitutionally entrenched governing powers accompanied by a politically volatile intergovernmental relations environment, service delivery infrastructure that is entirely out of pace with population growth,30 and the challenge of having to address residual localized damage from climate change.
In this respect, Chapter 6 of the Intergovernmental Panel on Climate Change (IPCC) Sixth Assessment Report states with high confidence that '[i]n all cities and urban areas, the risk faced by people and assets from hazards associated with climate change has increased', and further that '(g)lobally, the most rapid growth in urban vulnerability and exposure has been in cities and settlements where adaptive capacity is limited, especially in unplanned and informal settlements in low-and middle-income nations and in smaller and medium-sized urban centres'. 31t further states that an additional 2.5 billion people are projected to be living in urban areas by 2050, with up to 90% of this increase concentrated in the regions of Asia and Africa. 32These scientifically grounded assessments suggest a definite correlation between urban growth and climate vulnerability, a link of particular relevance to the African city.
The United Nations (UN) Habitat 2022 World Cities Report, Envisioning the Future of Cities, which reflects on urban development globally, further indicates that 'Africa is the least urbanized, but most rapidly urbanizing, region in the world', and further that 'in many African countries, urbanization is occurring at lower levels of income compared with other developing regions.This phenomenon has been referred to as the weakening of the historical link between urbanization and prosperity'. 33The report states that rapidly urbanizing cities in Africa and Asia, for example, are more vulnerable to climate change and least able to respond to its effects.As already suggested, they are hampered by limited financial, human, and technical resources as well as weak institutions and governance structures relating to disaster mitigation and preparedness.At the same time, these cities contribute very little to global warming, making their suffering disproportionate. 34he foregoing considerations warrant caution against a blanket celebration of 'the city' in the context of international law and global climate governance, as it may inadvertently homogenize cities and overlook their diverse capacities and roles.The institutional environment in which southern African cities govern continues to be shaped by the ongoing process of state formation, which is 'hugely different in the Global North and South',35 while many African governments still find themselves 'in the throes of an uncertain transition'. 36This call for diversification and words of caution on geographical under-representation are certainly not new, 37 but it is an increasingly urgent issue.Inclusive consideration of how the world is and ought to be responding to climate change is particularly pressing in policy instruments and scholarship that focuses on the role of cities in climate change governance and the advancement of the international climate change law agenda.Context-specific understanding and distinction is necessary because of the constraining institutional, political, and legal environments in which many cities in southern Africa govern and plan, and are expected to transform and execute positive and sustainable influence, notwithstanding the real-life severity of the climate change impacts in the region. 38

Cities can use law and legal action to drive climate change response at the local level.In a joint project of the Sabin Center for Climate Change Law 39 and the C40 Cities network 40 it transpired that three categories of legal intervention enable cities to drive climate action.These are litigation, legal reform initiatives, and pioneering city-level policies or legislation. 41It was found that these legal interventions may assist with the removal of legal barriers to climate action; help to clarify and obtain powers; and influence national government policy or corporate activities, enabling them to undertake more ambitious climate action. 42Other authors highlight very specific possibilities within one or more of these three categories.Rumble states, with reference to legal reform initiatives and governance instrumentation in general: In the case of climate change, the extent of the challenge is only now being experienced, and the required response is anticipatory in nature.Yet legislative mechanisms can and do play a critical role in empowering governments to take action, creating certainty; powerful incentives and disincentives; structures; institutions; and mechanisms to facilitate a more co-ordinated, effective and mandatory response. 43 agree that the role of legislative mechanisms and the local governance instruments provided for in law (be it national or subnational law) are particularly relevant for urban climate governance.Examples abound of how municipal spatial planning, demand management, financial (market-based) and different environmental management tools (especially in the waste sector) may be used innovatively for greenhouse gas (GHG) emissions reductions and improved community resilience. 44In this regard, 37  Van der Berg and Verschuuren draw on specific examples to explain how local law and policy instruments can be used for so-called 'coping adaptation' (for example, collaborative local rehabilitation and recovery schemes), incremental adaptation (for example, open space reserves to limit the heat island effect), and transformational adaptation or climate resilience. 45There are also reports and case studies that reflect on cities using pioneering local policies or legislation to limit carbon-intensive energy consumption, to regulate how buildings are designed and built to withstand climate shocks and decarbonize, as well as to incentivize people to use modes of transport other than road vehicles. 46In other documented examples we see how cities make use of collaborative city projects or initiatives (soft and hard measures) 47 to experiment with climate change mitigation and adaptation. 48However, while most of these projects and experiments are highly innovative and encouraging, and are testimony to the bold steps that cities are willing to take to address climate change, their legal status, rights-based and justice implications, as well as their longevity, remain under-explored. 49hat interests us, though, is that 'development in many countries suggests that municipalities do not fully exploit their authoritative powers and are reluctant to apply authoritative modes of governing through regulatory measures and strategic planning'. 50In the remainder of this article we look into the extent to which eight cities in four countries in southern Africa appear to be empowered.We are interested in determining whether and how local law and policy powers have thus far been leveraged towards climate action at the local level, what the status quo suggests in terms of the hype around cities and their role in global climate governance, and the research left to be done in the region.The cities of Harare and Bulawayo (Zimbabwe), Windhoek and Swakopmund (Namibia), Gaborone and Francistown (Botswana), and Cape Town and eThekwini (Durban) (South Africa) were all selected on the basis of their being some of the largest urban centres in the countries under study. 51

An increasing number of African countriessuch as Kenya, Uganda, Nigeria, Rwanda, and South Africaare in the process of developing, or have already developed, national climate change laws or amended sectoral legislation.These legislative developments advance the objectives and vision of climate change policy and the nationally determined contributions (NDCs) regime under the 2015 Paris Agreement. 52The potential of subnational law and policy reform processes, however, should not be gainsaid, as we have hoped to argue thus far.Below, we take this argument one step further as we reflect on the status, functional responsibilities, and governing authority (agency) of eight cities in Zimbabwe, Namibia, Botswana, and South Africa relative to that of national and other levels of government.This general analysis is later used to contemplate whether and how local governing power has translated into city-level climate change action in the respective countries thus far.

Zimbabwe
The Constitution of Zimbabwe is a decade old and provides for three government tiers: national, provincial, and local. 53Local government comprises urban and rural local authorities.Within a system theoretically designed for cooperative government, clear provision is made to protect local democracy, although the Constitution does not explicitly guarantee any other basic features of local autonomy.The Constitution provides very generic powers and functions of local government, the detail of which depends on national legislation, including the Urban Councils Act. 54For example, the Constitution does not explicitly give local authorities the power to raise revenue; nor does it limit the national executive's oversight of these local authorities.That said, the intent to devolve power, responsibilities, and resources is a clear feature of the Constitution and promises a local government that is better empowered than the one Zimbabwe historically had.The Constitution envisages local authorities exercising devolved powers and not only delegated powers.This is promising from the perspective of local environmental and climate governance, yet it remains the case that Acts of Parliament detail local government authority and powers. 55Consequently, in the absence of clear constitutional allocation and division of authority, the national sphere of government remains capable of centralizing power.As alluded to above, the national government also fulfils a supervisory role, which reportedly has been exploitedcities run by opposition parties are said to be easily declared dysfunctional and their autonomy undermined and denied. 56The current central government led by the Zimbabwe African National Union -Patriotic Front (ZANU-PF) is also characterized as anti-devolutionist and is perceived to be determined to weaken devolution of governing power. 57e that as it may, the Urban Councils Act empowers local councils to engage in several environmentally relevant functions such as the collection, treatment and disposal of sewage and stormwater, water supply and water pollution control, as well as landuse planning and natural resource conservation. 58Councils are empowered to make bylaws on matters specified in the Act or on anything that is incidental to or connected with a matter so specified. 59This suggests that for the sector areas (functions) mentioned above, bylaws may be passed by local authorities.Notably, though, the Minister of Local Government must approve these. 60oreover, under the provisions of the Regional Town and Country Planning Act, planning authorities, including Urban Councils and Rural District Councils, are required to create master and local plans for development. 61These plans, however, must be approved by the national Department of Physical Planning.Depending on the innovative interpretation of this function, these local governance instruments arguably could also be directed at environmental outcomes and climate response action at the local level.

Namibia
The Constitution of Namibia 62 does not stipulate city-level functions.This is despite the constitutional recognition of local authorities (alongside their powers to make bylaws).Instead, municipal functions are determined by Acts of Parliament, 63 as is the case in Zimbabwe.The Namibian Constitution further makes no explicit mention of intergovernmental cooperation, and it is also not made explicit in national legislation (with the exception of references to decentralization).However, Namibia has a comprehensive legal framework aimed at establishing, enforcing, and regulating decentralization through various instruments, ostensibly aimed at improved intergovernmental cooperation. 64The most prominent instruments include Chapter 12 of the Constitution concerning regional and local governments, the Local Authorities Act, 65 the Regional Councils Act, 66 and the Decentralization Enabling Act. 67lthough decentralization in Namibia has been on the cards since its independence in 1990, it has not attained much success and is an ongoing process (evidenced by the 2016 Brief on the Status of Decentralization Policy Implementation). 68Furthermore, the issues concerning intergovernmental cooperation and decentralization are complex and multifaceted. 69A large portion of the decision-making power remains in the hands of central government, as only certain functions relating to health, education, social services, land, public works, and rural water supply and sanitation have been decentralized. 70The limited number of functions allocated for delegation and the absence of devolved functions over the last three decades have been said to allude to stagnation in Namibia's decentralization process. 71There is also limited fiscal decentralization, worsened by restricted revenue-generating powers and resource allocations devolved by central government in comparison with the transfer of administrative functions. 72urthermore, poor human capital in local and regional authorities affects their ability to perform functions transferred to them from central government. 73amibia's Local Authorities Act defines the powers, duties, and functions of local authorities. 74An analysis of the latter instruments shows no substantial legislative or other powers in relation to land-use planning or disaster risk management, for example, but cities do have extensive powers related to the supply and management of water, 75 and the regulation, restriction, prohibition, and control of the use, sinking or maintenance of wells or boreholes necessary or conducive to the supply of water to residents. 76The Act further provides for the powers and functions of cities regarding sanitation, waste management, 77 electricity distribution, the creation of housing schemes, 78 as well as the provision and maintenance of sewerage and draining systems 79 (including public sewers, sewage works, and stormwater drains within or outside its area). 80In the context of stormwater discharge into public watercourses, local authorities possess the power to demand that an owner of immovable property lacking adequate provision for sewage disposal construct a private sewer, for example.Local authorities may also take appropriate measures to ensure the owner's compliance with this requirement within a 30-day timeframe. 81This may be perceived as further evidence of the role of cities in safeguarding water sources in Namibia.
Namibian local authorities are also engaged primarily in providing electricity and overseeing issues pertaining to its distribution.The Local Authority Act provides cities with the power to supply electricity (or gas) to residents as well as any person other than a resident in its area. 82Notably, the Public and Environmental Health Act provides for important and related duties that concern cities and their role in the prevention of the outbreak of diseases and the managing of environmental health challenges. 83The Act states that local authorities must take precautions to prevent the outbreak or prevalence of infectious, communicable, non-communicable, and contagious diseases, and promotes primary health care programmes in local authorities. 84Furthermore, the Act suggests several environmental health duties. 85Given the specific impacts of climate change that Namibia faces, each of the aforementioned functional areas could play a significant role in formulating local-level responses.

Botswana
Botswana operates a two-tier government system consisting of central and local government, with no provision being made for cooperative government as is the case with 77 Ibid., s. 30(1)(c).With regard to waste services, local authorities in Namibia are afforded the power to provide and maintain the destruction or removal of nightsoil, slop water, garden and stable litter, rubbish, abandoned vehicles, animal carcasses, and any refuse or unhealthy matter. 78Ibid., ss.30(1)(i), 57(1)(a), 57(1)(b)-(c), 58.It is noteworthy that the establishment of the housing scheme requires prior endorsement from the Minister and must comply with any conditions prescribed in that respect.Particularly, the Act determines that cities may construct, acquire, maintain, sell, or let dwellings.The latter powers also extend to the granting of loans to persons to access housing as envisioned in the Act; to assist banks to grant loans to persons to acquire or construct accommodation; and to establish a housing fund alongside housing schemes.Albeit seemingly incidental, these provisions may prove valuable in terms of future mitigation and adaptation strategies of Namibian cities, particularly in providing adequate housing for vulnerable communities affected by climate change. 79Local Authorities Act 23 of 1992, s. 30(1)(b). 80Ibid., s. 38(1)(a). 81Ibid., s. 38(3)(a)-(b). 82Ibid., ss.30(1)(f), 53. 83Public and Environmental Health Act 1 of 2015, s. 3. 84  Transnational Environmental Law, 12:3 (2023), pp.567-593 Zimbabwe and South Africa, for example. 86Instead, local government in Botswana is perceived as the creation of central government, which culminates in the latter dictating to the former. 87Unlike the situation in Zimbabwe and Namibia, the Constitution of Botswana 88 makes no provision for local government; nor does it assign any powers to local authorities.Local government autonomy is very limited, aggravated by its dependency on central government for revenue.Local government matters are regulated under the Local Government Act, 89 which establishes local authorities (known as councils), for each administrative district. 90They must perform and exercise their functions to promote the health, safety, and well-being of the areas in which they have been established. 91The functions of local authorities are set out in Schedule I of the Act and include, but are not limited to, safeguarding and promoting public health, waste management, and the provision of water.Section 11(2) of the Act, however, empowers the Minister of Local Government and Rural Development to bestow additional functions or substitute any of the mentioned local government functions. 92lthough the Act allows local government to publish bylaws, the exercise of local legislative power is subject to central government approval.For instance, section 45 of the Act provides that the Minister of Local Government and Rural Development must approve all municipal bylaws.If a bylaw concerns service and users' fees for services, for example, the Minister must consult other relevant Ministries. 93Thus, the autonomy of local government and its power to legislate is somewhat restricted.In fact, according to Maundeni, central government in Botswana is extensively involved in the running of local government affairs, effectively wrestling out local authorities. 94he situation is further perpetuated by poorly defined relationships between the authorities. 95Notwithstanding express provision for intergovernmental cooperation and relations between the two tiers of government, some scholars argue that the local and central authorities have worked well over the years. 96This may bring some de facto relief in a system where local government's power to govern in the realm of the environment and climate change is marginal.

South Africa
Following apartheid, the Constitution of South Africa established a system of so-called wall-to-wall local government comprising three categories of municipalities (local, district, metropolitan). 97These operate in a nested quasi-federal government system made up of a national, provincial, and local government sphere.Local government has significant autonomy with executive 98 and legislative 99 authority on matters (i) set out in Chapter 7 and Schedules 4B and 5B of the Constitution, and (ii) that may have been assigned to it.Some of the matters listed are air pollution control, building regulations, electricity and gas reticulation, municipal planning, municipal health services, municipal public transport, domestic waste management, and water and sanitation services. 100The Municipal Systems Act 101 is a national statute that reiterates local government's constitutional executive and legislative authority.Under the Act, municipalities may exercise legislative and executive authority by developing and implementing bylaws, policies, plans, strategies, and programmes, and by setting targets for delivery, for example. 102One of the most influential governance instruments at the disposal of local authorities is the so-called 'integrated development plan' with which municipalities can set and plan for strategic objectives, including environmental objectives.Quite a few national environmental sector Acts, 103 and the soon-to-be passed Climate Change Bill, 104 compel municipalities to adopt local sector plans (such as local waste management plans, biodiversity management plans, estuarine management plans, climate change response implementation plans) as part of their integrated development planning.
The democratic government design further makes ample provision for cooperative government and the Constitution lays down explicit principles in this respect, 105 fortified by the national Intergovernmental Relations Framework Act. 106The emphasis falls on cooperation among organs of state albeit without compromising the autonomy of, for example, municipalities.The law provides for national and provincial oversight and monitoring of the work of local government as part of a system of checks and balances for municipal service delivery and a healthy developmental-oriented local government.National and provincial intervention in the affairs of local government is permissible when specified requirements are met;107 such intervention has become quite widespread in the face of severe municipal service delivery failures. 108A relevant and interesting development is the changing features of local party politics of recent years whereby more and more coalition governments are formed as the ruling African National Congress (ANC) party seems to be losing ground at municipal level. 109The long-term impacts of municipal coalition governments on the effective execution of municipal legislative and executive authority for environmental, climate change and other outcomes remain to be seen.

A review of the climate change-specific and sectoral local laws and policies in two cities in each of the countries under consideration casts light on how local government powers and intergovernmental relations complement or constrain city-level climate action.It also allows for a comparative analysis of whether and how cities in the southern African region use the powers they have, and how this measures up against some of the documented city-level climate change initiatives elsewhere in the world. 110

Zimbabwe: City of Harare and City of Bulawayo
The City of Harare is the capital of Zimbabwe with an urban population of approximately 2.4 million. 111Its climate change profile is distinguished by a persistent rise in temperature and a trend of reduced and unpredictable rainfall. 112Climate projections for the next 40 years signify a decline in precipitation and a further increase in the mean temperature, portending the possibility of persistent droughts in the area. 113The impact of climate change in Harare is placing a considerable strain on already limited water supply, an effect that is compounded by rapid expansion of the city's population. 114The latter challenge has had a consequential effect on the wetlands in the city area, which had previously served as vital natural purification systems, which helped to avert disease outbreaks. 115Consequently, the increased risk of infectious diseases such as typhoid and cholera is an unwelcome reality. 116The main climate risks and vulnerabilities in the City of Harare include extreme heatwaves, floods, epidemics, food insecurity, and inadequate working and living conditions. 117Vulnerable communities, such as those residing and working in the city's informal areas, are particularly affected.The unintended consequences of climate change in the area include reduced economic and urban agricultural activity, among others. 118he climate vulnerability of Bulawayo, the second-largest city in Zimbabwe, is primarily as a result of its semi-arid climate. 119Climate change has caused a considerable reduction in precipitation and an increase in atmospheric pressure, leading to new seasonal patterns in the area. 120The ramifications of climate changesuch as decreased rainfall, extended dry spells, and heatwaveshave had a profound impact on food security, economic activity, and public health in the city. 121The latter situation significantly affects community resilience, and is further attributable to a historical dearth of water and acute water stress in the area. 122either the City of Harare nor the City of Bulawayo have local climate change laws or policies in place.However, several sectoral local laws and policies of potential relevance exist; they mirror the functional areas of local government in Zimbabwe, referred to earlier.The City of Harare, for example, has local laws on water, 123 spatial planning,124 building standards and codes:125 sectors that are generally known to play an incidental but important role in managing the effects of climate change.In the case of Zimbabwe, these local instruments date back many years, and none mention climate change expressly.Similarly, the City of Bulawayo has local plans in place concerning water and sanitation, which provide regulations on, for instance, protection of watercourses, pollution of streams, and irrigation water. 126Given that Bulawayo is located in a semi-arid area, and its water sources are placed at further risk because of the effects of climate change,127 the latter plans could prove valuable for the city in the management and safeguarding of water resources.Of further relevance is the Urban Agriculture Policy.This policy provides for various objectives concerning the use of water and land for urban agriculture, and promotes water conservation and anti-pollution policies (such as that, wherever possible, rainwater should be harvested for urban agricultural use, and that drip irrigation methods to conserve water should be employed in cases where groundwater is used). 128The fostering of sustainable urban agricultural practices may be considered innovative in the context of the often drastic effects of climate change on the agricultural sector and water availability in the country.
There are some, mostly ad hoc, local climate change projects in these cities.For example, in the City of Harare, a zero-waste project was initiated by the community and is supported by the city council. 129Of the two cities, the City of Bulawayo boasts arguably the most innovative project entailing multiple uses of land, specifically via developing solar farms over its cemeteries. 130

Namibia: City of Windhoek and Municipality of Swakopmund
The effects of climate change in the City of Windhoek, the capital of Namibia, poses significant risks to the city's environmental, social, and economic well-being. 131indhoek, because of its semi-arid location, already faces water scarcity issues.This problem is further intensified by the severe droughts and increasing temperatures that the city experiences. 132This, coupled with the city's precipitous population growth (currently estimated at well over 400,000 and expected to double over the next 20 years) and rapid urbanization, places its strained water supply, said to be at its upper limit in 2020, at further risk. 133While the area is known for its low rainfall, an increase in intense rainfall events has been noted to cause flash floods, which affect the developmental activities of the city. 134The aforementioned challenges detrimentally affect the large impoverished portion of the city's population, and further exacerbate living conditions in its various informal settlements where access to water and sanitation is already limited. 135he Municipality of Swakopmund, being a coastal city, is also quite vulnerable to the effects of climate change such as sea-level rise and coastal erosion. 136As such, the city is susceptible to flooding and storm surges, which may have an impact on its infrastructure, including roads, water supply systems, and buildings. 137Given that Swakopmund's economic activity is highly dependent on tourism, such climate change-related consequences may prove dire. 138Sea-level rise may further stress the city's ecosystem services and the various socio-economic sectors dependent thereon. 139dditionally, the severe water shortages in Namibia, exacerbated by climate change, affect human settlements in coastal cities such as Swakopmund because of these cities' dependence on underground aquifers. 140esearch indicates that an Integrated Climate Change Strategy and Action Plan for the City of Windhoek has been developed, although the plan is not yet publicly available. 141The Municipality of Swakopmund does not have local laws regarding climate change; over the years, however, both Namibian cities have developed local laws concerning water, 142 energy, 143 spatial planning, 144 and building codes and standards. 145ith the exception of the Municipality of Swakopmund Structure Plan 2020-2040, none of the aforementioned instruments address climate change explicitly; nevertheless, they regulate incidental yet important sectors that play a role in the governance of climate change at the local level.These sector areas also correspond with the functional areas of competence of local government mentioned earlier.
Further, the Swakopmund Structure Plan 2020-2040 aims to assist the municipality in following an 'integrated and holistic future-orientated planning approach that promotes sustainable use of the finite available resources (both natural and man-made), to maximise the development potential of Swakopmund'. 146he Plan includes a vision for creating a climate-resilient, sustainable, liveable, and inclusive city. 147The Plan is extensive and prioritizes, for example, sustainable modes of transportation and clean industries, the creation of shared open spaces, the conservation of the natural environment, cooperative governance, and informed decision making. 148The Plan appears to be innovative given that its text identifies and pledges to address sectors that do not fall explicitly within the governing power of local government in Namibia.
As far as local climate change projects in the two cities are concerned, the City of Windhoek, through its Environmental Management Division, has participated in the National Greenhouse Gas Working Group aimed at compiling the country's GHG inventory and reporting to the UN.Furthermore, the Council has engaged in the Transformational Leadership Training on Climate Change for City Executives towards mainstreaming climate change in the City's planning and practices, 149 among other initiatives. 150On the other hand, no climate change projects could be identified in the Municipality of Swakopmund.

Botswana: Gaborone and Francistown
Gaborone has a semi-arid climate with erratic and unpredictable (and very limited) rainfall. 151The city has experienced severe droughts in recent years: 152 in 2015-16, for instance, it experienced droughts that led to the drying up of the Gaborone Dam. 153A recent analysis of spatio-temporal rainfall variability in Botswana predicts decreasing rainfall in Gaborone. 154As in the case of the cities in Zimbabwe and Namibia, droughts and water scarcity affect the agricultural sector and food security in the area. 155Studies in 2014 indicated a decline in the capacity of the Gaborone Reservoir, which supplies water to the city, such that it was impossible at the time to pump out water. 156Water scarcity has also historically led to water rationing in Gaborone, which left citizens without water for some days. 157The city has also been affected by heavy flood disasters. 158ising temperatures in Francistown similarly culminate in heatwaves, drought, loss of biodiversity, and extinction of certain species in the area. 159An empirical study conducted in 2017 indicated an increase in heatwave severity in the city. 160This understandably has adverse implications for agriculture and the water sector, leading to food insecurity. 161A recent study on spatio-temporal rainfall variability in Botswana confirmed a decrease in rainfall in Francistown 162 but, as in the case of Gaborone, Francistown has also been affected by disastrous flooding. 163otswana does not have climate change-specific local (city-level) laws and policies, as far as could be established.Seemingly, climate change governance is the prerogative and mandate of central government.The two cities under consideration also have no climate change projects, although there could exist undocumented local climate change initiatives.
Despite its limited governing authority, the local authorities of Gaborone adopted the so-called Gaborone City Council (General) Bylaws in 1966.Francistown followed suit and published the Francistown City Council (General) Bylaws in 1967.These sets of bylaws provide for waste management, thereby prohibiting littering and the accumulation of waste, for example.The bylaws further prohibit activities such as the disposal of carcasses in an unauthorized area, and the burning of any grass, refuse or rubbish; they also prescribe building standards for the construction of bakeries, butcheries, and fishmongers.The local laws of the two cities do not explicitly mention climate change but the peripheral issues they cover may at least offer a starting point for localized climate change responses in the country.

South Africa: City of Cape Town and eThekwini
As a result of keen academic and media interest in the topic, a fair amount of research is available on the impact of climate change in Cape Town and Durban (eThekwini). 164limate change is also behind some of the most severe disasters (droughts, floods, runaway wildfires) to have hit Cape Town and Durban in recent years.Cape Town is situated in the renowned Cape Floristic Region (a global biodiversity hotspot) and is further surrounded by 307 kilometres (km) of coastline.This unique environmental setting makes the city particularly vulnerable to climate change.This is so especially as it is also home to a large number of seasonal wetlands, freshwater bodies and watercourses amidst worrying socio-economic challenges such as high levels of unemployment, poverty, informality, an acute housing crisis, as well as health challenges from communicable and non-communicable diseases. 165Cape Town is also a significant GHG emitter, relative to its size. 166urban is a coastal city of which the economy is very much driven by industrial activity from which significant GHG emissions cannot readily be detached.The city is projected to experience increased temperatures and periods of drought, more intense storms and flooding, together with sea-level rise. 167The combination of these impacts threatens water security and water quality, posing the risk of increased vector-borne and water-borne diseases, loss of biodiversity, changes in species' migratory patterns, and negative impacts on food production. 168The city's Climate Change Strategy states that these impacts 'could be compounded by other drivers unrelated to climate change like inappropriate management of built and natural infrastructure, poor planning and poor governance'. 169n the context of this article's focus, Cape Town and Durban may be deemed two climate governance champions in the southern African region.There are ample examples of how the two cities have been using their legislative and executive authority to address the causes, risks, and impacts of climate change as directly relevant for these urban areas.Cape Town's Climate Change Strategy 2021, for example, states that the city's climate change-response ambition is to become a resilient, resource-efficient and carbon-neutral city, and sets out ten principles underpinning the Strategy. 170he city also has a set of Carbon Neutral 2050 Commitments in which it commits to achieving carbon neutrality by 2050. 171By virtue of its membership of the C40 Cities Network, the city has voluntarily committed to what may be styled 'Cape Town's C40 Commitments', 172 which include but are not limited to the Net-Zero Carbon Buildings Commitment and Green and Healthy Streets Declaration. 173The City of Cape Town has also published a Climate Change Action Plan 2021, which sets out actions to implement its Climate Change Strategy 2021.The plan also defines the role of the city in responding to climate impacts while transitioning to a carbon-neutral local economy. 174In addition, Cape Town's Resilience Strategy 2019 was adopted following a severe drought of three years and aims to strengthen the city's resilience against potential shocks such as storms and floods. 175he The eThekwini Metropolitan Municipality adopted its Municipal Adaptation Plan: Health and Water in 2009.The Plan sets out the city's climate-related challenges and highlights its need for adaptation.The Plan also identifies interventions in the water and health sectors as central to the city's adaptation response.The city later adopted the Durban Climate Change Strategy of 2014, reflecting on the city's projected climate change responses and some goals to be achieved. 176Five years later, eThekwini adopted its Climate Action Plan 2019, which highlights the climate challenges in the city area and sets out the projected impacts. 177The Plan continues to set long-term targets and actions, which must be achieved by 2050; these include carbon-zero new buildings and municipal infrastructure. 178The city also has incidentally relevant bylaws including, for example, its Stormwater Management Bylaws of 2020, which provide for measures to adapt to climate change and the densification of built-up areas. 179oth cities have ongoing climate projects.The City of Cape Town, for example, has a project on the roll-out of free basic electricity where the local authority provides a lifeline tariff for households that use less than 450 kilowatt hours (kWh) of electricity per month, receiving the first 50 kWh free. 180The city and the C40 City Finance Facility further signed a Memorandum of Understanding in 2022 through which the city will undertake two projects aimed at achieving a carbon-neutral city status by 2050. 181he first project relates to the building of green infrastructure and the rehabilitation of waterway projects. 182The second relates to the city's pursuit of an energy efficiency programme and renewable energy generation through the building of a groundmounted solar photovoltaics generation plant. 183Thekwini, in collaboration with the C40 City Finance Facility, is running a so-called Transformative Riverine Management Project (programme). 184The project aims to adapt the 7,400 km of streams and rivers in the city to protect against flooding, drought, and higher temperatures that are projected to occur as a result of climate change.According to the C40 City Finance Facility, this eThekwini project is nested in the original Durban Climate Change Strategy of 2014 and the most recent Climate Action Plan of 2021. 185   By now, the scientific community largely agrees on the interwoven web of causes and impacts, the amount of resources (especially of a financial kind) and high-level political commitment and coordination needed to see a meaningful and long-lasting response to climate changeat all levels and scales of governance.186 The literature on the role of cities in global climate governance is vast, as academics, non-governmental organizations, global city networks, UN bodies, and activist organizations continue to produce reports and case studies on city-level climate initiatives.187 It is agreed that the extent of the climate problem is just too far-reaching for any city or municipality to tackle it on its own, and in the limited scope of its governing authority and geographically delineated governing space.188However, the role of cities and their municipalities in climate change becomes apparent when we consider that they often oversee integral responsibilities.These responsibilitieswhich include air quality control, water services, domestic waste management, electricity distribution, stormwater management, and spatial planningare fundamental components interwoven with the causes and impacts of climate change.189 Yet, the climate crisis places significant pressure on local governance, intensifying the struggles of local authorities in certain regions and countries to deliver and perform basic services.This is an aspect that we left unexplored in this article.We aimed, however, to determine with reference to Botswana, Zimbabwe, Namibia, and South Africa whether and how local law and policy powers have thus far been leveraged towards climate action at the local level.
A functional comparative reading of the extent to which local law, policy, local projects and political choices in the four countries gravitate towards city-level climate responses showed a smorgasbord of developments.Firstly, there is a discernible correlation between local government agency, powers and autonomy, and the extent to which cities in Zimbabwe, Namibia, Botswana, and South Africa have thus far adopted direct and indirect climate response measures in local laws and policies.The absence of local climate action in Gaborone and Francistown matches the lack of municipal autonomy in the country's legal system, whereas the significant level of autonomy of South African municipalities and the relative local autonomy in Namibia clearly shine through in their progressive climate response measures provided for in local laws, policies, and projects.Countries such as Botswana, where local government laws and plans must be approved by central authorities, also seem to have little going at the city level.
Secondly, climate gains may be made by clearly allocating functional responsibility to different organs of state and through compliance with national laws.Without exception, the eight cities under discussion have adopted bylaws and local policies that speak to their clearly allocated functions such as water provision, waste management, and air pollution.With the exception of South Africa and, to some degree, Namibia, there seems to be limited appetite to take local climate action on top of the actions that can be integrated with the classic (traditional) functions and services of local government.This may have less to do with political will and commitment and more to do with unfunded mandates in the face of already stretched municipal budgets.
Thirdly, while our research did not venture into any specific intergovernmental arrangements and structures for collaborative public climate change governance, it would appear that cities in countries with explicit provision for cooperative governance more boldly engage in local law and policy initiatives in the functional areas relevant to climate change.The bylaws and local policies of Cape Town and Durban, for example, mention South Africa's national vision and developments for climate-resilient development, and would seem to complement efforts at the provincial and national government levels.Some local climate change initiatives in Windhoek and Swakopmund appear to be more policy-oriented and geared towards collaboration with central government initiatives.This is in contrast to initiatives in Zimbabwean cities, which seem more practically focused and indicative of own initiative.
Fourthly, and related to the issue of local government autonomy, fiscal autonomy and the strength of local economies seem to line up with the level of local climate action in the cities of southern Africa.While it is true that Cape Town and Durban enjoy constitutional local autonomy of a kind unknown in Namibia and Botswana, it is noticeable that these two South African cities have particularly strong mixed local economies, which makes them slightly less dependent on intergovernmental financial transfers, for example.The contrary is also true in that both South African cities have economic activities that significantly contribute to GHG emissions, which may serve as an impetus to have climate change on the local authority agenda.
Ultimately, however, (local) law and policy is what it does.We agree that cities are much more than 'miniature republics ', 190 and that the real role of southern African cities in addressing the causes and consequences of climate change stretches beyond the law and policy architecture (or the absence thereof).Considerably more may in fact be going on de facto to promote the development of resilience and adaptation in local communities.At the same time, anecdotal evidence suggests there are serious discrepancies between reality and the strategic vision and objectives of local laws and policies in the region.For example, despite its progressive strategies, local policies and programmes, the relatively well-resourced metropolitan municipality of eThekwini in South Africa still battles (more than one year down the line) to repair the most basic of city infrastructure damaged during the April 2022 Durban floods.It may be necessary, therefore, to supplement the doctrinal legal study we have undertaken with on-the-ground research into the real impact of local projects, policies and bylaws, and other ad hoc-type mitigation and adaptation initiatives.The impact of political dynamics at central and subnational levels may be as important to explore.
From our perspective, there exist six additional areas in the southern African urban context that warrant further investigation.These include the relevance of climate change litigation and national legal (climate change law) reform initiatives for local or city-level law and policy action.Equally significant is the suite of authoritative modes of governing available to southern African cities, encompassing alternative or quasi-legal regulatory measures, and municipal strategic and spatial planning.Further, understanding the legal levers and barriers to collaborative urban climate governance in cities that involve public authorities and private actors alike is paramount. 191Another area to explore is the local-level impact of cities' transnational engagement in climate change initiatives, especially those developed and funded by global city networks such as ICLEI and C40.Next, it is necessary to consider the potential impact of trends to recentralize governing power in southern Africa on the globalization of urban climate governance.Lastly, an exploration of the relationship between climate science, knowledge dissemination, and the priority that cities and other public authorities in the southern African region give to climate change adaptation and mitigation responses in local laws and policies is critical.

City of Cape Town has several bylaws and local policies which are incidentally relevant to its climate response.These include, inter alia, its Air Quality Management Bylaws 2016, Electricity Supply Bylaws 2010, Stormwater Management Bylaw 2005, Integrated Risk Management Policy 2016, and Municipal Disaster Risk Management Plan 2015.
