Agroforests exist in many forms, for example, across Indonesia, but are largely absent from policy documents. Development planners have long seen them as backward, but agroforests, or domesticated forests, with high (agro) biodiversity, reconcile instrumental (goal-oriented) and relational (harmony-oriented) values of nature for various stakeholders. Agroforests combine farmer-managed, remnant, and tolerated spontaneously established trees; they blend market demands and local needs in labor-efficient, nature-based land use. Could explicit recognition of agroforests, interfacing with these values, help achieve the Kunming-Montreal Global Biodiversity Framework? In the local cultural context, men and women may express appreciation for agroforest structure and function differently. The scarcity of the remaining natural forests increases agroforests’ role as diverse reservoirs. Agroforests are under threat of publicly subsidized conversion to monoculture tree crop plantations, exposing farmers to economic and ecological risk. Reimagining biodiversity conservation solutions where agroforests remain part of the landscape is an opportunity not to be missed.

Effectiveness of the Yangambi Biosphere Reserve in Reducing Deforestation in the Democratic Republic of the Congo
Establishing protected areas creates an opportunity to reduce deforestation. This study aims to inform the Congolese government’s efforts to promote forest and biodiversity conservation by assessing the effectiveness of the Yangambi Biosphere Reserve (YBR) in reducing deforestation. Group and individual interviews designed to understand the causes of pressure on forest cover in the Yangambi landscape complemented satellite imagery analyses. The results indicate that deforestation inside the YBR is not significantly different from outside the YBR. They demonstrate the lack of impact of the YBR in reducing deforestation. The dependence of communities on forest resources would have led to an explosion of bare and fallow land replacing forest areas. A sufficient budget allocation for conservation coupled with capacity building of managers to implement integrated conservation projects could offer alternative livelihoods at the community level, reduce pressure on natural resources from local development and ensure biodiversity conservation in and around the YBR.
Using Red List Indices to monitor extinction risk at national scales
The Red List Index (RLI) measures change in the aggregate extinction risk of species. It is a key indicator for tracking progress toward nine of the Aichi and many proposed post-2020 Global Biodiversity Framework Targets. Here, we consider two formulations of the RLI used for reporting biodiversity trends at national scales. Disaggregated global RLIs measure changing national contributions to global extinction risk and are currently based on five taxonomic groups, while national RLIs measure changing national extinction risk and are based on taxonomic groups assessed multiple times in country. For 74% of nations, the disaggregated global RLI is currently based on three or fewer taxonomic groups. Meanwhile, national RLIs from selected pilot countries Finland, South Africa, and Brazil are computed from twelve, eight, and nine taxonomic groups, respectively. The national RLI and the disaggregated global RLI measure different aspects of biodiversity, in that the former detects national trends in populations of species for which each country is responsible while the latter provides standardized comparisons of nations’ contributions to the global extinction risk of the same species groups. As governments commit to the post-2020 Global Biodiversity Framework, we encourage them to monitor a standard set of taxonomic groups representing different biomes using both RLI formulations to ensure effective target tracking and accurate feedback on their conservation investments.
Quantifying and mapping species threat abatement opportunities to support national target setting
The successful implementation of the Convention on Biological Diversity’s post-2020 Global Biodiversity Framework will rely on effective translation of targets from global to national level and increased engagement across diverse sectors of society. Species conservation targets require policy support measures that can be applied to a diversity of taxonomic groups, that link action targets to outcome goals, and that can be applied to both global and national data sets to account for national context, which the species threat abatement and restoration (STAR) metric does. To test the flexibility of STAR, we applied the metric to vascular plants listed on national red lists of Brazil, Norway, and South Africa. The STAR metric uses data on species’ extinction risk, distributions, and threats, which we obtained from national red lists to quantify the contribution that threat abatement and habitat restoration activities could make to reducing species’ extinction risk. Across all 3 countries, the greatest opportunity for reducing plant species’ extinction risk was from abating threats from agricultural activities, which could reduce species’ extinction risk by 54% in Norway, 36% in South Africa, and 29% in Brazil. Species extinction risk could be reduced by a further 21% in South Africa by abating threats from invasive species and by 21% in Brazil by abating threats from urban expansion. Even with different approaches to red-listing among countries, the STAR metric yielded informative results that identified where the greatest conservation gains could be made for species through threat-abatement and restoration activities. Quantifiably linking local taxonomic coverage and data collection to global processes with STAR would allow national target setting to align with global targets and enable state and nonstate actors to measure and report on their potential contributions to species conservation.
Over half of threatened species require targeted recovery actions to avert human-induced extinction
Averting human-induced extinctions will require strong policy commitments that comprehensively address threats to species. A new Global Biodiversity Framework is currently being negotiated by the world’s governments through the Convention on Biological Diversity. Here we explored how the suggested targets in this framework could contribute to reducing threats to threatened vertebrates, invertebrates, and plants, and assessed the importance of a proposed target to implement recovery actions for threatened species. Although many of the targets benefit species, we found that extinction risk for over half (57%) of threatened species would not be reduced sufficiently without a target promoting recovery actions, including ex situ conservation, reintroductions, and other species-specific interventions. A median of 54 threatened species per country require such actions, and most countries of the world hold such species. Preventing future human-induced extinctions requires policy commitments to implement targeted recovery actions for threatened species in addition to broader efforts to mitigate threats, underpinned by transformative change.
The rights way forward: reconciling the right to food with biodiversity conservation
The current paradigm of biodiversity conservation, with its continued focus on the notion of pristine nature, has resulted in the separation of humans and nature at the expense of both biological and cultural–linguistic diversity. The continued annexation of land for the cause of conservation has resulted in the curtailment of both rights and access to local and diverse food sources for many rural communities. Indigenous Peoples and local communities are fundamental to conserving biodiversity through sustainable use of nature despite repeated attempts to dispossess them from their lands, cultures and knowledge. It has been this traditional and land-based knowledge that has contributed to the conservation of biodiversity whilst also supporting healthy, diverse and nutritious diets. If we are to achieve a more just and sustainable future, we need to continue to centre conservation initiatives around rights, access and equity whilst respecting a plurality of perspectives, worldviews and knowledge systems. Here we review alternative approaches that help reconcile the right to food with biodiversity conservation, such as biocultural rights, rights-based approaches and integrated land management schemes, with the aim of identifying optimal ways forward for conservation that break away from the dichotomous view that pits people against nature and instead embrace the importance of this symbiotic relationship.
Responsible drone use in biodiversity conservation: Guidelines for environmental and conservation organisations who use drones
Key messages
- Drawing on interdisciplinary research expertise, this document lays out principles for best practice for the use of drones as part of biodiversity conservation and/or efforts to defend rights to land.
- We outline the risks that drones can pose to local communities and wildlife and propose mitigating strategies for minimising these risks.
- As drone imagery often captures identifiable human subjects, we highlight the importance of practices to avoid capture or deleting imagery where not needed, to reduce the risk of conservation data being used for other political purposes.

Trophic Resource Use by Sympatric vs. Allopatric Pelomedusid Turtles in West African Forest Waterbodies
Organisms that are similar in size, morphological characteristics, and adaptations, including vertebrates, often coexist by partitioning the available resources (food, space, and time). So, studies of the dynamics of these cases of coexistence are scientifically interesting. Here, we study a coexistence case of two species of freshwater turtles inhabiting the forest waterbodies of West Africa, focusing on the dietary habits of the two species. We found that both turtle species are omnivorous generalists, eating both vegetal and animal matter abundantly. However, there were clear interspecific differences, with the larger of the two species (P. cupulatta) eating more vertebrates (mainly fish but occasionally other vertebrates), whereas P. castaneus consumed more invertebrates. These patterns appeared consistently within the species and across sites, highlighting that the same patterns were likely in other conspecific populations from the Upper Guinean forest streams (Côte d’Ivoire and Liberia). Our study also showed that interspecific competition for food does not occur between these two species; instead, previous studies uncovered that a clear partitioning of the habitat niche occurs. We conclude that the food resource is likely unlimited in the study areas, as it is not the case in more arid environments (since food shortages may occur during the dry season). We anticipate that, within the Pelomedusidae communities throughout Africa, intense competition for food probably occurs in the Sahel and Sudanian vegetation zones, particularly during the dry months, but is unlikely within the Guinea and wet savannah region and even less likely in the Guineo-Congolian rainforest region.
Human Dimensions of Pangolin Conservation: Indigenous and Local Knowledge, Ethnozoological Uses, and Willingness of Rural Communities to Enhance Pangolin Conservation in Nepal
Understanding local knowledge about wildlife, local uses, and local people’s willingness to support conservation activities are crucial factors in formulating wildlife conservation strategies. We conducted a semi-structured questionnaire survey of 1017 people from 105 villages located in different ecological regions across all seven Provinces of Nepal. We performed generalized linear mixed modeling (GLMM) to investigate the key drivers influencing respondents’ knowledge about pangolins, based on a questionnaire score. We identified provinces, ethnicity, occupation, gender, and age group as strong predictors influencing local ecological knowledge about pangolins. The respondents from provinces in the western part of Nepal represented significantly lower knowledge scores than the respondents from the eastern and central provinces. Similarly, respondents belonging to non-Indigenous groups, students, females, and people aged between 18–30 years had the lowest knowledge scores about pangolins. A range of uses and beliefs about pangolins were reported across Nepal, and 48% of respondents believed that pangolin scales and meat were used for traditional medicines. The majority of respondents (71.1%) were willing to support pangolin conservation in their local areas. Our study suggests that awareness programs, alternative livelihood, and income-generating trainings for local communities could be helpful in enhancing the long-term conservation of pangolins in Nepal. Increased efforts are needed in western Nepal and across the country with non-Indigenous communities, females, young people, and students. Thus, this study offers an important baseline to help design and execute effective community-based conservation actions and management decisions for pangolin conservation.
Connected Conservation: Rethinking conservation for a telecoupled world
The convergence of the biodiversity and climate crises, widening of wealth inequality, and most recently the COVID-19 pandemic underscore the urgent need to mobilize change to secure sustainable futures. Centres of tropical biodiversity are a major focus of conservation efforts, delivered in predominantly site-level interventions often incorporating alternative-livelihood provision or poverty-alleviation components. Yet, a focus on site-level intervention is ill-equipped to address the disproportionate role of (often distant) wealth in biodiversity collapse. Further these approaches often attempt to ‘resolve’ local economic poverty in order to safeguard biodiversity in a seemingly virtuous act, potentially overlooking local communities as the living locus of solutions to the biodiversity crisis. We offer Connected Conservation: a dual-branched conservation model that commands novel actions to tackle distant wealth-related drivers of biodiversity decline, while enhancing site-level conservation to empower biodiversity stewards. We synthesize diverse literatures to outline the need for this shift in conservation practice. We identify three dominant negative flows arising in centres of wealth that disproportionately undermine biodiversity, and highlight the three key positive, though marginalized, flows that enhance biodiversity and exist within biocultural centres. Connected Conservation works to amplify the positive flows, and diminish the negative flows, and thereby orientates towards desired states with justice at the centre. We identify connected conservation actions that can be applied and replicated to address the telecoupled, wealth-related reality of biodiversity collapse while empowering contemporary biodiversity stewards. The approach calls for conservation to extend its collaborations across sectors in order to deliver to transformative change.
