Soil erosion responses to climate change in a tropical monsoon‐dominated river basin ‐ A geospatial perspective

open access: yesRiver, EarlyView.
Climate change is projected to intensify soil erosion in the Chalakkudy River Basin, with bare lands and steep uplands emerging as the most vulnerable hotspots under high‐emission scenarios. Forested areas showed greater resistance to soil erosion, highlighting the importance of targeted soil conservation for sustainable watershed management in ...

Limited elephant impacts on baobabs despite increasing elephant densities in a newly established protected area

open access: yesConservation Science and Practice, EarlyView.
Researchers combined aerial and ground surveys to map baobab distribution and assess elephant herbivory impacts on baobabs across Karingani Game Reserve, Mozambique. Researchers found that aerial surveys were an effective tool for mapping baobabs and that baobabs were more likely to occur closer to permanent water, at lower elevations, and in areas ...

Assessing forest fragmentation and biodiversity impacts in sub‐Saharan Africa: Methodological challenges and conservation strategies for small‐scale agricultural landscapes

open access: yesAgrosystems, Geosciences &Environment, Volume 9, Issue 2, June 2026.
Abstract Tropical forests in sub‐Saharan Africa (SSA) harbor around one‐third of the world's species but are becoming more fragmented due to the expansion of human settlements and small‐scale agricultural (SCA) areas. This study systematically reviewed the approaches and methods used to analyze forest fragmentation and its impact on biodiversity in SSA,
