Drivers and spatial patterns of avian defaunation in tropical forestsBackgroundTropical forests harbor an immense diversity of bird species, but hunting and wildlife trade are driving widespread declines in bird populations. Unlike habitat loss, hunting often occurs in seemingly intact forests, making its impact more difficult to detect. Birds are harvested for both subsistence (food) and commercial purposes (pet trade), but the spatial extent and drivers of avian defaunation remain poorly understood. This study aims to assess the factors influencing bird population declines and map defaunation patterns across tropical forests. Open access copy available |
Cascading effects of contemporaneous defaunation on tropical forest communitiesBackgroundDefaunation, caused by hunting and habitat fragmentation, is a major threat to biodiversity in tropical forests. It disproportionately affects large-bodied vertebrates, which play key roles as seed dispersers, seed predators, and herbivores. The loss of these animals can have cascading effects on plant populations, altering species composition, seed dispersal, and plant recruitment. This study reviews empirical evidence from 42 studies to understand how defaunation influences plant-animal interactions, plant demography, and overall community diversity.

Navigating power in conservationBackgroundConservation has traditionally centered on the natural sciences, but there is a growing recognition that it also deeply involves people and society. As a result, conservation efforts constantly navigate power dynamics, often without fully acknowledging them. Conservationists wield power when they decide which animals or plants to protect, where to focus their efforts, and how to implement them. Recognizing these power dynamics is essential for making conservation more effective, fair, and just. However, many conservationists either overlook or misunderstand the concept of power.

Placing diverse knowledge systems at the core of transformative climate researchBackgroundEffective solutions-oriented research values both the process and the outcomes, recognizing that genuine partnerships across knowledge systems emerge within broader political shifts. Yet, international environmental organizations often exclude non-Western knowledge from their frameworks, reinforcing epistemic injustices that mirror social and political inequalities. Transformative change in addressing the climate crisis demands a critical examination of how knowledge and power interact, ensuring the integration—not marginalization—of diverse perspectives.

Key challenges for governing forest and landscape restoration across different contextsBackgroundForest and Landscape Restoration (FLR) restores ecological integrity, strengthens climate resilience, enhances human well-being, and increases the productivity of deforested or degraded landscapes. By integrating diverse land uses and restorative actions, FLR balances environmental and socio-economic needs. Global agreements, including the UN Convention on Biological Diversity, the Paris Climate Agreement, and the Bonn Challenge, recognize its importance. Effective governance—defined by clear rules and inclusive decision-making—plays a critical role in ensuring FLR's success. Open access copy available |
Forest carbon offsets and carbon emissions trading: Problems of contractingBACKGROUND:Monitoring and measuring carbon fluxes in forestry are complex and costly, exacerbated by asymmetric information and inadequate institutions, leading to unstable values in carbon trading. Good governance is essential for effective contracting in the carbon market but often falls short, leading to misaligned incentives and principal-agent problems. These issues frequently delay successful contracting, potentially resulting in corruption and disputes over carbon offset claims. Available with subscription or purchase |
The contribution of forest carbon credit projects to addressing the climate change challengeBACKGROUND: Historically, forestry projects face significant challenges due to uncertainties around the permanence of carbon storage and the complexities of carbon measurement. These challenges limit their effectiveness and integration into international carbon markets, such as those established under the Kyoto Protocol, which have predominantly favored other types of carbon reduction projects over forestry. The paper focuses on the potential of forest carbon credit projects, particularly in the context of enhanced carbon sequestration accounting standards and their integration into carbon markets.

The principles of natural climate solutionsBACKGROUND:Natural Climate Solutions (NCS) were consolidated as a holistic concept in 2017, leveraging human interventions in land management to mitigate climate change by adapting existing conservation knowledge for climate action. Over the past six years, the implementation of NCS has seen a rapid increase in attention, as indicated by a significant rise in social media discussions and funding commitments, though these efforts still fall short of the levels required to meet global climate mitigation goals.
