Article Synopsis
- * Erosion rates in the Saint-Esprit catchment were found to be significantly high (10 t ha per year), exceeding typical tolerable soil loss rates for tropical regions, leading to increased remobilization of chlordecone into water bodies.
- * The research indicates that contamination from chlordecone may last for thousands of years in impacted areas, stressing the importance of improving land management practices to reduce soil erosion and protect water bodies from further contamination.
Rapid demographic growth in tropical islands can exacerbate conflicts and pressures on natural resources, as illustrated by the French island of Mayotte where resources are limited. In only 10 years, uncontrolled migration and population growth (+80% of population between 2002 and 2021) have led to a pronounced 3600% increase in deforestation rates (2010-2014) and an intensification of agricultural practices, escalating conflicts over limited land, water, and biodiversity resources. Implementing an original multi-proxy approach to sediment cores, our study reveals a staggering 300% acceleration in erosion during the first wave of migration (2011-2015), followed by a further 190% increase (2019-2021) under sustained migratory and demographic pressures.
