The Critically Endangered Nubian Flapshell Turtle (Cyclanorbis elegans) is found in the White Nile River system in South Sudan and northern Uganda. Over the past few decades, its populations have sharply declined, primarily due to human-induced threats, leading to its near-extinction across almost its entire range. In this paper, we present the results of a comprehensive threat analysis undertaken to pinpoint the challenges confronting the species within its natural habitat, specifically in the only known sites where it currently exists. We aimed to develop a conceptual framework to understand causal relationships among driving forces, threats and the target species. This framework allows the visualisation and analysis of the web of intricate interactions that contribute to the species’ decline and vulnerability. We convened a panel of experts who identified three primary direct threats to the Nubian Flapshell Turtle: (1) Sand mining (IUCN code 3.2); (2) Overfishing by native fishers and refugees (code 5.4) and (3) Habitat loss at nesting sites (code 7.3). Among these threats, overfishing had the largest geographical extension, the highest intensity and duration, while habitat loss occurred at the highest frequency. These threats varied significantly in intensity and frequency. Additionally, when assessing the overall magnitude of these threats, habitat loss and overfishing had the highest impact, with significantly higher scores compared to sand mining. Our experts also identified the underlying driving forces behind these threats: (1) Economic interests driving sand mining activities along the Nile; (2) The influence of civil conflict and refugee populations, which contribute to the demand for bushmeat; (3) the Chinese expatriates, that lead to overfishing; (4) The removal of bank vegetation serves as a catalyst for habitat loss at nesting sites. The resulting conceptual framework serves as a valuable tool for defining targeted conservation measures for each distinct threat.

Advancing Global Biodiversity Governance: Recommendations for Strengthening the Post-2020 Global Biodiversity Framework
Reversing ecosystem degradation and halting global biodiversity loss due to climate change and other anthropogenic drivers are essential for socioeconomic development and human wellbeing, as well as for advancing global sustainability. The latest initiative in this direction is the ‘Post-2020 Global Biodiversity Framework’, which establishes a blueprint for global coordinated action towards development of national and regional strategies targeting conservation and sustainable utilization of biodiversity. By supporting the notion of ‘ecological civilization’, it emphasises the need for transformative strategies to conserve, monitor and sustainably manage ecosystems by 2030. Arguably the articulation of fit-for-purpose goals and targets is a key precondition for achieving this vision by enhancing cooperation and influencing the development of implementation strategies and regulatory instruments at national and local levels. The present Policy Analysis critically reviews the key features of the draft Post-2020 Global Biodiversity Framework and suggests recommendations to further strengthen it.
Comparison of soil microfauna diversity between a burnt and unburnt peatland in Indonesia
Approximately 95 percent of peatlands in Indonesia have been degraded by forest fires or converted for cultivation. Forest fires release huge volumes of carbon dioxide into the atmosphere and have caused severe damage to Indonesia’s ecosystems and biodiversity, particularly in Kalimantan and Sumatra. Even though understanding post-fire environmental dynamics and biodiversity changes would be highly beneficial in determining restoration processes, baseline analyses on biodiversity and soil moisture content in burnt and degraded peatlands remain limited. Consequently, this research explores and assesses soil macrofauna diversity and properties, and changes in soil fauna patterns in a burnt peatland area currently undergoing restoration with the establishment of a bioenergy plantation in Buntoi village, Central Kalimantan province, Indonesia. Results from the study site show peatland fires causing hugely reduced numbers of soil mesofauna and macrofauna individuals, and bioenergy tree survival rates being higher in plots on unburnt than burnt peatland. Fauna species diversity, gauged using the Shannon diversity index (H), was lower in burnt than unburnt areas, though some orders – such as Hymenoptera – appear to adapt well to burned areas as we found them in both burnt and unburnt plots. Results show a significant correlation between peat fires and biodiversity. We also found that the more seriously fire damaged bioenergy trees were, the higher the likelihood of biodiversity decreasing. Generally, soil moisture and nutrient availability are key factors supporting higher soil invertebrate diversity in unburnt areas. However, results showed no significant correlation between soil moisture content and soil fauna diversity in our research site. In conclusion, understanding the severe impacts of fire on peatlands will make people more aware and less likely to use fire for clearing and preparing peatlands, thereby prolonging their use.

Global importance of Indigenous Peoples, their lands, and knowledge systems for saving the world’s primates from extinction
Primates, represented by 521 species, are distributed across 91 countries primarily in the Neotropic, Afrotropic, and Indo-Malayan realms. Primates inhabit a wide range of habitats and play critical roles in sustaining healthy ecosystems that benefit human and nonhuman communities. Approximately 68% of primate species are threatened with extinction because of global pressures to convert their habitats for agricultural production and the extraction of natural resources. Here, we review the scientific literature and conduct a spatial analysis to assess the significance of Indigenous Peoples’ lands in safeguarding primate biodiversity. We found that Indigenous Peoples’ lands account for 30% of the primate range, and 71% of primate species inhabit these lands. As their range on these lands increases, primate species are less likely to be classified as threatened or have declining populations. Safeguarding Indigenous Peoples’ lands, languages, and cultures represents our greatest chance to prevent the extinction of the world’s primates.
Relational values of forests: Value-conflicts between local communities and external programmes in Sulawesi
Studies found that rapid decline of biodiversity and ecosystems globally have adversely affected an estimated 1.6 billion rural people whose livelihoods both directly and indirectly depend on forests. To halt the loss of forests and other natural ecosystems that simultaneously support rural livelihoods, various external programmes have been developed and applied, including market-based and rights-based approaches. However, rapid biodiversity and ecosystem decline continues, and better incentives or more secure rights have not always led to local community participation and improved livelihoods. This suggests the need to better explain local communities’ motivations in nature stewardship. We conducted a study of local communities in two villages in Sulawesi who voluntarily maintain forests but showed resistance to participation in formal Social Forestry programmes. The study aimed to identify motivations and underlying reasons of community preferences, guided by two research questions: (i) how did local people value forest landscapes? and (ii) how did those values interact with externally driven Social Forestry programmes? We applied the Relational Values concept to understand a community’s relations with the forest (or its elements) and land and identified points of value divergence. Data collection involved in-depth semi-structured interviews, focus group discussions framed by the principles of Appreciative Inquiry, participant observation and land use/land cover change analysis. Our findings show that people value their forests in relation to their identity, ancestral heritage, sense of place and spiritual values. We also identified the points of value divergence and their underlying reasons of resistance towards externally driven forestry programmes. This study thus contributes to the broader conceptualisation of values in conservation and community participation by providing empirical evidence on the importance of the Relational Values framework in understanding the motivation and behaviour of nature stewardship and in the evaluation of value conflicts.
Complexity of zoning management in biosphere reserves: the case of the Yangambi Biosphere Reserve in DRC
Riparian communities activities threaten conservation in biosphere reserves in the Democratic Republic of Congo (DRC). The Yangambi Biosphere Reserve (YBR) is no exception to this degradation. Thus, the objective of the presents study was to elucidate the local factors underlying the high pressure on natural resources and analyze the complexity of biosphere reserve zoning management using an interdisciplinary approach combining document review, field surveys and semi-structured interviews. Our results revealed that the zoning applied to the YBR did not take into account social dynamics. With population growth, the riparian community is doomed to remain in restricted areas, leading to over-exploitation of the space and land degradation, forcing the population to travel long distances to reach fertile plots into the protected area. Also, the lack of employment and the absence of participatory zoning also exacerbate tensions between the manager and the riparian community. For an effective management of the YBR, political authorities should become more involved in the participatory zoning of conservation areas and village exploitations. In addition, they should improve farming techniques to mitigate soil degradation.
