We assess progress toward the protection of 50% of the terrestrial biosphere to address the species-extinction crisis and conserve a global ecological heritage for future generations. Using a map of Earth's 846 terrestrial ecoregions, we show that 98 ecoregions (12%) exceed Half Protected; 313 ecoregions (37%) fall short of Half Protected but have sufficient unaltered habitat remaining to reach the target; and 207 ecoregions (24%) are in peril, where an average of only 4% of natural habitat remains. We propose a Global Deal for Nature—a companion to the Paris Climate Deal—to promote increased habitat protection and restoration, national- and ecoregion-scale conservation strategies, and the empowerment of indigenous peoples to protect their sovereign lands. The goal of such an accord would be to protect half the terrestrial realm by 2050 to halt the extinction crisis while sustaining human livelihoods.

Two processes for regional environmental assessment are currently underway: the Global Environment Outlook (GEO) and Intergovernmental Platform on Biodiversity and Ecosystem Services (IPBES). Both face constraints of data, time, capacity, and resources. To support these assessments, we disaggregate three global knowledge products according to their regions and subregions. These products are: The IUCN Red List of Threatened Species, Key Biodiversity Areas (specifically Important Bird & Biodiversity Areas [IBAs], and Alliance for Zero Extinction [AZE] sites), and Protected Planet. We present fourteen Data citations: numbers of species occurring and percentages threatened; numbers of endemics and percentages threatened; downscaled Red List Indices for mammals, birds, and amphibians; numbers, mean sizes, and percentage coverages of IBAs and AZE sites; percentage coverage of land and sea by protected areas; and trends in percentages of IBAs and AZE sites wholly covered by protected areas. These data will inform the regional/subregional assessment chapters on the status of biodiversity, drivers of its decline, and institutional responses, and greatly facilitate comparability and consistency between the different regional/subregional assessments.

Restoring the degraded Atlantic Forest is one of the biggest conservation challenges in Brazil. In a biome with high human presence, understanding the potential for restoration approaches, such as agroforestry, to provide benefits to smallholder farmers and biodiversity is essential in developing equitable restoration strategies. Smallholder or family farmers are essential to national food security, producing most fruit and vegetables consumed in Brazil. Their farms can also provide ecological stepping stones for biodiversity. To better understand their role in Atlantic Forest restoration, this study explores the use of agroforestry by smallholder farmers from the Movimento Sem Terra (MST), the Rural Landless Workers' Movement, in Pontal do Paranapanema. We use quantitative and qualitative data to assess farmer perceptions of the measures which support agroforestry farming, barriers to implementation and its impact on indicators of wellbeing. We find agroforestry farmers report significant benefits in 8 of 18 tested indicators. Attitudes to agroforestry are varied, but common themes emerge including the high value of tree cover for shade and cooling effects, and the difficulties in selling agroforestry products. Our results show lack of policy support and initial investment needs are the biggest constraints to agroforestry, but opportunity cost is not considered a large barrier. Tailored policies and financial measures are needed to integrate thousands of smallholder farmers into the Atlantic Forest restoration agenda, helping to reach biome restoration targets while supporting rural livelihoods and national food security. Further research is required into links between additional socio‐economic and biogeographical variables and agroforestry uptake in the region.

The Black Lives Matter Movement, which gained unprecedented global momentum in mid‐2020, triggered critical reflection on systemic discrimination of disadvantaged groups across many domains of society. It prompted us, as early‐career researchers (ECRs) in conservation science, to examine our own awareness of ongoing injustices within our field, the role we play in perpetuating or countering these injustices, and how to move forward. Colonialist ideologies and power dynamics throughout the history of conservation practice and research have left a long‐lasting legacy of inequality and systemic racism. While improvements have been made, these legacies continue to influence teaching and practice today. In this perspective piece, we reflect on the impacts of conservation’s colonial past and how the sector has developed. We then explore how current traditional routes into conservation, and the dominance of these approaches, can leave ECRs underprepared to address modern‐day conservation issues due to a limited understanding of conservation’s history and key theories from other fields. We end by offering a set of suggestions encouraging others to learn and practise fairer and more inclusive conservation practices.

Scientists have warned decision-makers about the severe consequences of the global environmental crisis since the 1970s. Yet ecological degradation continues and little has been done to address climate change. We investigated early-career conservation researchers' (ECR) perspectives on, and prioritization

Tropical forests play a major role in conserving biological diversity and providing ecosystem services (Barlow et al., 2018;Ferreira et al., 2018). Covering around 10% of the Earth's surface, they contain over half of the world's known species including 90% of terrestrial bird species (Barlow et al., 2018;Gibson et al., 2011) and are central to climate change mitigation (Gibbs et al., 2007). Estimates suggest the tropics lost 12 million ha of forest in 2018, with the average rate of loss of intact tropical forests tripling in the last 10 years to 4.3 million ha per year, an area the size of Belgium (Schulte et al., 2019). Deforestation continues to be the main driver of biodiversity loss in the tropics (Maxwell et al., 2016;Morris, 2010a) and the effects of forest loss, habitat fragmentation, and ecosystem degradation on biological diversity are well understood (Giam, 2017;Haddad et al., 2015;Morris, 2010b). As the implementation period of the Convention of BiologicalDiversity's (CBD) Strategic Plan for Biodiversity 2011−2020 comes
