Community-based natural resource management (CBNRM) has been a pervasive paradigm in conservation circles for three decades. Despite many potentially attractive attributes it has been extensively critiqued from both ecological and sociological perspectives with respect to theory and practice (for example Leach et al. 1999; Berkes 2004; Fabricius et al. 2004; Blaikie 2006). Nonetheless, many successful examples exist, although an equal number have seemingly not met expectations. Is this because of poor implementation or rather a generally flawed model? If the criteria and conditions for success are so onerous that relatively few projects or situations are likely to qualify, what then is the value of the model? The questions thus become: how and what can we learn from the past theory and practice to develop a new generation of flexible, locally responsive and implementable CBNRM models, and what are likely to be the attributes of such models?

The Andean páramo ecosystems host geodiversity of global importance, but also have important societal functions, including agricultural production and delivery of water to people and industry. Páramo geo-ecosystems are highly susceptible to environmental degradation because of their alpine relief, extreme climate and fragile soils. In contrast to other parts of the world, geodiversity assessment studies in the Andes are scarce. A geodiversity assessment method was adapted and used to produce a potential geoconservation map of the Andean páramo. The Las Lagunas area (Cajamarca, Northern Peru) has a rich archive of climate proxy data and landscape reconstruction, and plays a key role in the functioning of regional geo-ecosystems. Undisturbed proxies for climate change are contained in four Late-Glacial recessional complexes of its former local ice cap and in pollen records preserved in the post-glacial peat cover. These new findings were used to develop a refined chronostratigraphy of the Late-Glacial warming period in the Andes of Northern Peru. Geo-ecosystem functions (for example water and carbon storage) depend on the environmental vulnerability and disturbance of the landforms and deposits. Therefore, potential geoconservation areas that combine a high scientific value and environmental vulnerability with a low disturbance and low frequency of occurrence should be prioritized for geoconservation. Such a strategy should also optimize sustainable use of resources and development of these areas. Mountainous countries like Peru require future management strategies that recognize and incorporate potential geoconservation information in regional planning, to prevent unnecessary loss of irreplaceable soils, climate proxies and geo-ecosystem functions upon future changes in land use and climate.

Biodiversity management has traditionally followed two contradictory approaches. One champions ecosystem protection through rigorous law enforcement and exclusion of humans. The other promotes community-based sustainable use of natural resources. Participatory conservation, a major paradigm shift, nowadays strongly guides the concept of UNESCO Biosphere Reserves (BRs). In this paper, the rationale for community participation, and the perception of its effectiveness among BR managers are analysed. Within the World Network of BRs (553 sites in 107 countries) diverse participatory approaches are being tried to advance community-based natural resource management (CBNRM). Data from two parallel surveys, involving managers from 276 BRs worldwide, reveal how far this participation paradigm shift has really occurred, and its influence on managers’ self-evaluated effectiveness. There is substantial regional disparity, although in general BR managers endorse inclusive conservation, despite critical implementation hurdles. The process of participatory conservation carries new dangers for effective biosphere reserve management, when the aspirations of communities and other stakeholders do not ‘fit’ with a predetermined interpretation of sustainable development.

Interdisciplinarity can be interpreted broadly as an active, multi-faceted learning process between researchers from different disciplines to create a common ground for a special purpose. Interdisciplinary approaches are regarded as necessary in environmental research, especially in view of global environmental change. However, some argue there is a lack of genuine interdisciplinarity in environmental research. Polymaths can play a potentially important role in environmental research. Environmental polymaths can enhance the effectiveness of interdisciplinarity through their knowledge and understanding of different disciplinary languages, epistemologies and methodologies, and as such, should be acknowledged more explicitly in interdisciplinary discussions.

Community-based natural resource management (CBNRM) has been on the ascendancy for several decades and plays a leading role in conservation strategies worldwide. Arriving out of a desire to rectify the human costs associated with coercive conservation, CBNRM sought to return the stewardship of biodiversity and natural resources to local communities through participation, empowerment and decentralization. Today, however, scholars and practitioners suggest that CBNRM is experiencing a crisis of identity and purpose, with even the most positive examples experiencing only fleeting success due to major deficiencies. Six case studies from around the world offer a history of how and why the global CBNRM narrative has unfolded over time and space. While CBNRM emerged with promise and hope, it often ended in less than ideal outcomes when institutionalized and reconfigured in design and practice. Nevertheless, despite the current crisis, there is scope for refocusing on the original ideals of CBNRM: ensuring social justice, material well-being and environmental integrity.

Mesoamerica, Chocó and the tropical Andes are recognized as biodiversity hotspots where conservation action is urgently needed. Because World Wildlife Fund for Nature (WWF) ecoregions are commonly used as the basis for conservation decisions, an understanding of WWF ecoregions’ environmental heterogeneity and their representation in current protected areas (PAs) is important for identifying priority areas for conservation. Thirteen environmental domain classifications based on 22 climatic and topographical variables and the Shannon diversity index were used to quantify environmental diversity for each WWF ecoregion. The area of each environmental domain and ecoregion was compared with the World Database on Protected Areas 2007. The most environmentally-diverse ecoregions were poorly represented in the PAs and several ecoregions showed low environmental heterogeneity representation inside PAs, for example the Balsas depression, Sierra Madre del Sur and the Chiapas Sierras in Mexico, some sierras in Central America, the Middle Magdalena, inter-Andean valleys, the Eastern Cordillera of Colombia and the Western Moist Forest of Ecuador. Using WWF ecoregions as equivalent units for conservation and management can be misleading, given their environmental heterogeneity; therefore, they have limited usefulness in assessing environmental representation in PAs. An underestimation of environmental heterogeneity representation in PAs can have misleading implications for conservation actions in regions where detailed biological information is lacking. Conservation efforts should focus on the environmental domains and ecoregions showing high environmental heterogeneity that is poorly represented in PAs.

Interdisciplinary research has wide applicability to the environment and its management, and few areas can rival Brazilian Amazonia in terms of interdisciplinary challenges. Brazil's Ministry of Science and Technology currently makes interdisciplinary research an explicit priority, and to this end directs financing to large networks of researchers working in different institutions and fields. An impressive number of programmes support and carry out interdisciplinary research in the region, with varying success. Shifts in funding priorities are needed to maximize further advances.

Local community involvement in natural resource management can be critical to conservation success. Community participation in conservation efforts varies widely, reflecting a continuum from protectionist conservation mechanisms to programmes driven by local communities. Conservation is not one event, but an iterative process with many steps (planning, implementation, monitoring) each with an opportunity for different levels of participation. Barriers and triggers to more community involvement in management of the Cordillera Azul National Park (Peru) were examined. Eleven conservation officials and 73 community members provided information on levels of participation achieved at three management stages: Park establishment, management plan development, and management implementation. Park establishment was not a participatory process, owing to the expediency of the conservation agenda and a narrow window of political opportunity. Community involvement increased during the management plan development and its implementation, with communities eager to participate and a public-private partnership introducing new participatory management tools. However, a perceived lack of capacity in terms of community skills, funding availability, time and sufficient conservation personnel, and the definitions of participation used by different stakeholders, limited community involvement in decision-making processes. If conservation is to achieve more effective community involvement, long-term adaptive co-management approaches are needed that clearly define local participation, build capacity of all stakeholders and monitor levels of participation across all stages of project management.

Low-density residential development, the fastest growing land use in the USA, is increasingly occurring adjacent to protected areas and in areas of high biodiversity. Thus, determining the environmental impacts, including the cumulative impacts, of proposed residential developments is a pressing challenge. The relative abundance and species richness of anurans in 19 ponds surrounded by landscapes with varying ages of residential development were measured, while endeavouring to control for local habitat quality effects on the anurans. Age of residential development was a predictor in the best models describing the responses of four individual anuran species and total anuran relative abundance. In particular, all of the best models of gray treefrog Hyla versicolor relative abundance included age of residential development as a predictor. Present-day anuran communities in remnant urban ponds are evidently responding to the effects of residential development that occurred up to 54 years in the past.

Community based natural resource management (CBNRM) engages groups of citizens in collective action towards sustainable conservation and natural resource management (NRM) within and across various tenure regimes. Substantial differences exist between developing and developed countries in terms of conditions conducive to CBNRM. There are also contextual differences from national to local scales, across different ‘spaces’ and ‘places’ within each. This paper focuses on developed countries in deriving and synthesizing some concepts from systems theory and landscape ecology, with lessons from facilitating novel CBNRM arrangements. Understanding the landscape context of interacting levels and scales of social and ecological systems can inform institutional development of resilient CBNRM. Efforts to increase the scale and effectiveness of social-ecological sustainability can benefit from novel arrangements facilitating holistic integration of environmental conservation across levels of institutions of communities and government, including tenure regimes (type and ownership of resources as ‘property’). Property and policy, together with ‘place’ attachment of communities can be viewed within a landscape framework. Such a ‘landscape lens’ provides an interdisciplinary meld that is important to sustainable CBNRM, but sometimes forgotten (or avoided) in government planning, policy deliberation and action.

Considerable efforts have been put into collaborative conservation efforts across the globe. In the western USA, concern about declines of two sage-grouse species (Centrocercus urophasianus and C. minimus) has led to the creation of over 60 collaborative wildlife management partnership groups to develop and implement local sage-grouse management plans. These sage-grouse local working groups (LWGs) share a common goal, information, and policy environment, but were implemented in diverse ways. As a result, they provide a rare opportunity to study systematically the impact of contextual, organizational, institutional and process factors on local collaborative group success. Data from document reviews and an extensive survey of over 700 group participants from 53 sage-grouse LWGs were used to assess the success of this collaborative conservation effort and identify those group attributes that were related to successful implementation and funding of projects. Specifically, external, internal and emergent group characteristics were considered as likely predictors of LWG implementation success. The LWGs varied broadly in their achievements. The presence of a neutral facilitator, participants' feelings of ownership, groups whose local plans had more authority and early-stage group successes were significantly related to implementation success at the group level.

In recent decades, the interconnectedness of history and ecology has received increasing attention. Although necessarily interdisciplinary, efforts to study this interconnectedness had their roots either in the humanities and social sciences or in the natural sciences: scholars have tried either to understand more about nature with the help of history, or, about human history with the help of natural phenomena. As a result, theoretical studies about the integration of ecology and history try to answer two relatively distinct questions: ‘why ecology matters in history’ and ‘why history matters in ecology’. This paper sets out to systematize current knowledge on the latter question and to highlight those issues that have so far received less attention. The arguments can be grouped into three major themes. First, history matters in ecology because it aids understanding of current patterns and processes in nature. Second, because it fosters better informed management and policy decisions; and third, because it places ecology and conservation in a wider interdisciplinary context. Besides dealing with the perspectives of ecologists and conservationists, this paper also includes material from historians, anthropologists and archaeologists, that is, from scholars whose primary interest does not lie in ecological investigations, but who have, nonetheless, embraced the need for the integration of ecology and history.

Decentralization of forest management has become a common policy globally which has allowed communities to regain rights removed through colonization and central state management of forests. However, socioeconomic and environmental outcomes of such community-based forest management schemes have been mixed. Studies have shown the importance of institutions in influencing the success of these new governance arrangements. Based on an extensive literature review supplemented by qualitative research, using focus groups and semi-structured interviews, conducted in nine villages in the humid forest zone comprising three community forests, this research investigated the successes and challenges from decentralization of forest management in Cameroon. A key constraint on success was the inappropriate institutional structure at the local level with responsibility to manage community forests. Community forest management committees with no internally recognized legitimacy and dominated by local elites had replaced roles once played by traditional authorities. Qualitative research showed that in the humid forest zone of Cameroon, the system of accountability for forest resources, prior to the enactment of community forest legislation, included those with historical traditional cultural authority, in the form of clan or lineage heads, as well as the village chief, a legacy of colonial power. Village chiefs or other members of the village council are also selected on the basis of their good moral character. Community forest management committees that are a hybrid of customary authorities and other representatives of the population chosen following the criteria for local legitimacy may capture the best of historical social regulation and build on it so that the local committee may be seen as being accountable to the local population. Since such hybrid institutions are not without their risks, it is important that these institutions be accountable to a local democratic government to further increase their transparency and accountability. Models of community-based natural resource management that incorporate culturally appropriate requirements of legitimacy and accountability in crafting local institutions may have more success in accomplishing both socioeconomic and environmental goals.

Working across knowledge-based research programmes, rather than institutional structures, should be central to interdisciplinary research. In this paper, a novel framework is proposed to facilitate interdisciplinary research, with the goals of promoting communication, understanding and collaborative work. Three core elements need to be addressed to improve interdisciplinary research: the types (forms and functions) of theories, the underlying philosophies of knowledge and the combination of research styles; these three elements combine to form the research programme. Case studies from sustainability science and environmental security illustrate the application of this research programme-based framework. This framework may be helpful in overcoming often oversimplified distinctions, such as qualitative/quantitative, deductive/inductive, normative/descriptive, subjective/objective and theory/practice. Applying this conceptual framework to interdisciplinary research should foster theoretical advances, more effective communication and better problem-solving in increasingly interdisciplinary environmental fields.

Human activities may have detrimental effects on biodiversity, and appropriate economic valuation of biodiversity can provide additional motivation to protect it. To date, there are no estimates of visitor values for landscape and wildlife changes in the North Pennines (UK) and very few studies have explored competing influences of landscape and biodiversity in public preferences. Contingent valuation estimates of visitor values for the North Pennines landscape and biodiversity, as expressed in voluntary contributions, were used to assess the importance of different factors in influencing these valuations. Policy-linked scenarios were developed, each representing the outcome of a particular policy direction such as grouse-moor specific subsidies, back-to-nature subsidies, or a ban or decline in red grouse shooting. The influence of management information provision was tested and economic values were elicited for a number of alternatives. Landscape and biodiversity were both found to be important in preference formation. In particular, respondents highly valued a mosaic landscape with increases in blanket bog and the associated increases in rare and threatened birds and mammals. Notably, significant negative valuations were obtained for some of the scenarios presented. Provision of land use information did not significantly influence visitors' valuations, a surprising result given the controversial nature of one of the primary land uses, namely red grouse shooting.

Various management approaches have been proposed to address the alarming depletion of marine coastal resources. Prominent among them are community-based management and the establishment of marine protected areas (MPAs). The overall poor performance of MPAs can be traced to a failure to effectively include local communities in the design and implementation of relevant measures. Recent efforts have incorporated aspects of community-based management into a hybrid form of management, which ideally builds upon existing local management practices. A key challenge lies in the development of appropriate frameworks that allow for the successful participation of local communities in management. A review of studies on MPA design and community-based marine resource management and fieldwork observations provides suggestions on how to address current socioeconomic shortcomings in MPA design and implementation, successfully involving local communities in order to provide a better local basis for effective larger MPA networks. A combination of MPA tools as the formal frame and community-based natural resource management as the adaptive core that recognizes local communities as allies, not aliens, is needed to develop successful conservation approaches.

Efforts to promote popular participation in forest management in Sub-Saharan Africa have faced many obstacles and disappointments. Although promises of improvements in relation to forest management, rural livelihoods and local enfranchisement have been achieved in some cases, accounts of frustration outnumber those of success. Focusing on participation through democratic decentralization (namely the transfer of meaningful discretionary powers to local representative authorities), this paper reviews recent empirical studies on the outcomes of popular participation in forest management. The implementation of decentralization of forest management, and ecological, livelihood and democracy outcomes are examined, and misconceptions in analyses of decentralized forestry are explored. The expected benefits of democratic decentralization within forestry are rarely realized because democratic decentralization is rarely established. In most cases, local authorities do not represent the local population or their space of discretion is so narrow that they have little effect on management. There is little official local management taking place, even under so-called decentralized or participatory management arrangements. If ever significant space for local discretion under democratic authorities is created, researchers will have the opportunity to study whether democratic decentralization can deliver the theoretically promised positive outcomes. Nevertheless, some cases shed light on effects of local decision making. Three general observations are made on effects of decentralization. First, environmental, livelihood and democracy objectives are not always mutually reinforcing, and under some circumstances they may be at odds. Second, environmental effects of improved forest management often result in benefits accruing to distant or higher-scale aggregate populations, while local communities carry the costs. Third, poor peoples' use of natural resources to maintain their livelihoods often conflicts with profit and revenue interests of local elites, national commercial interests and governments. A negotiated minimum social and environmental standards approach to decentralization of forest management may safeguard essential ecological functions and at the same time protect essential livelihood and economic values of forests at all scales of society. The remainder of decisions, such as how forests are used, by whom and for what, could then be safely placed at the discretion of responsive local representatives.

Community-based natural resource management has been accused of failing on social, economic or ecological grounds. Balanced assessments are rare, however, particularly in West Africa. This paper examines the first 10 years of Ghana's Wechiau Community Hippo Sanctuary using an evaluation framework that considers socioeconomic and ecological outcomes, as well as resilience mechanisms. Building upon traditional taboos against the killing of hippopotami, this initiative has attempted to conserve an imperilled large mammal, protect biodiversity and alleviate abject poverty amidst a bush meat crisis and complex ethnic diversity. Findings show that the Sanctuary has improved local livelihoods by spurring economic diversification and infrastructure development rates 2–8 times higher than in surrounding communities. Simultaneously, threats to biodiversity have subsided, hippopotamus numbers have remained stable and the Sanctuary's riparian habitats now harbour more bird species than comparable areas nearby. Improved social capital, true empowerment, an equitable distribution of benefits, ecological awareness among children and support for the Sanctuary, even amongst community members who were disadvantaged by its creation, speak to good long-term prospects. Risks remain, some of which are beyond the community's control, but evidence of socioecological resilience suggests that capacity exists to buffer risks and foster sustainability. Lessons learnt at Wechiau translate into recommendations for the planning, implementation and evaluation of future community-based conservation initiatives, including greater interdisciplinary integration and the use of adaptive co-management approaches.

A quasi-experimental design was used to test the hypothesis that there will be a significant improvement in both coastal resource management (CRM) and human reproductive health (RH) outcomes by delivering these services in an integrated manner as opposed to delivering either in isolation. The CRM, RH and integrated CRM+RH interventions were tested in three island municipalities of Palawan. Pre-project (2001) and post-project (2007) measurements of dependent variables were gathered via biophysical and community household surveys. Regression analyses indicate the CRM+RH intervention generated higher impacts on human and ecosystem health outcomes compared to the independent CRM and RH interventions. Improvements in coral and mangrove conditions are attributed to the effects of protective management by collaborating peoples’ organizations. The same institutions managed RH activities that enabled contraceptive access and a significant decrease in the average number of children born to women in the study area. Other trends showing a significant reduction in income-poverty among young adults infer added value. To ensure long term sustainability of CRM gains and prevent over-use of coastal resources, integrated forms of management that engage communities in the simultaneous delivery of conservation and family planning services are needed.

Ability to demonstrate statistical patterns of distribution by threatened species and by their potential competitors will determine success in forecasting locations at greatest risk, and ability to target management efforts. A self-organizing map algorithm (SOM) was used to derive probabilities of presence of native (Austropotamobius pallipes) and exotic (Orconectes limosus, Pacifastacus leniusculus and Procambarus clarkii) crayfish species with respect to physical and land-cover variables in a large stream system, using a simple presence-absence dataset of species. Crayfish were sampled at 128 sites representing 86 rivers. The probability of occurrence of the native species increased at higher elevations above sea level and lower temperatures; populations appeared to be mostly confined to headwater streams where exotic competitors were unable to withstand the colder conditions. The distribution of exotic species was correlated with anthropogenic factors, such as the degree of urbanization and agricultural land area. Complementary modelling tools, such as GIS and SOMs, can help to maximize the information extracted from available data in the context of biological conservation.
