Drivers of global mangrove loss and gain in social-ecological systemsBackgroundThe gain and loss of mangrove forests worldwide depends on both biophysical factors and socioeconomic factors. With global mangrove cover decreasing since the 1990s and biophysical pressures on mangrove forests (i.e., shoreline erosion, extreme weather events) increasing due to climate change, it is important to understand which forms of national conservation policies, programs, governance, and local economic activity most rapidly reverse the rate of loss of mangrove forests.

The drivers and impacts of Amazon forest degradationBackgroundThis research examines the growing threat of forest degradation across the Amazon, a region critical to global carbon balance and biodiversity. Beyond deforestation, widespread disturbances such as fire, edge effects, selective logging, and extreme drought have emerged as major causes of ecological and social disruption. These human-driven stressors, intensified by climate change, now affect approximately 2.5 million km²—around 38% of remaining Amazon forests—posing risks comparable to deforestation itself.

Our land, our life: A participatory assessment of the land tenure situation of the Indigenous peoples in Guyana. Report for Region 8BackgroundFrom 1995 onwards, the government of Guyana began to address undecided Amerindian claims by demarcating land in villages where titles had already been granted, granting title extensions, and grant new titles. This report outlines the findings and recommendations of a participatory assessment of land tenure security among indigenous people in present-day northwestern Guyana. Open access copy available |
Croissance et assimilation nette foliaire de jeunes plants de dix arbres de la forêt guyanaise, cultivés à cinq niveaux d'éclairementbackgroundThis study assesses the growth of ten species of tropical rainforest trees under 5 different light conditions. Conclusions & TakeawaysThe authors find that juveniles of most species did best in 25-45% sun light conditions and that the lowest light levels severely decrease growth across species.

Quelques réussites dans la réduction de la déforestation: Des pays tropicaux où les politiques de protection de la forêt et de reboisement ont fonctionnéThis report highlights successes of developing countries and their strategies for reducing deforestation and as a result, their emissions of greenhouse gases. The authors note that decreases in deforestation are primarily a result of REDD+ programs, including payments for ecosystem services, better law enforcement, governance reforms, moratoria on deforestation practices, and incorporating the environment in development efforts. Other successes come from policy changes and programs that have had intended and unintended positive impacts on forests.

Evaluación técnica y financiera de la silvicultura desarrollada en un bosque natural de la Guayana venezolana (Technical and financial evaluation of silvicultural management in the Venezuelan Guayana)Los autores analizan el funcionamiento de una empresa forestal que ejecuta, desde 1996, un plan de ordenación y manejo forestal en un bosque seco tropical, El Dorado- Tumeremo, con una superficie productiva 66 000 ha (Estado Bolívar, Venezuela). Se aprovechan unas 30 especies según diámetros mínimos de corta, clasificadas según su potencial comercial: las comerciales (Hymenaea courbaril, Pouteria caimito, Spondias mombin, Cordia alliodora, Andira sp., Manilkara bidentata y Peltogyne pubescens), las potencialmente comerciales (Cordia bicolor, Fagara martinicense, Tetragastris panamensis, Ceiba pentandra, Brosi- mun alicastrum, Aspidosperma megalocarpum, Astronium lecontei) y las que no tienen valor com Open access copy available |
