Journal: :Land 2023

The Brazilian semiarid region (BSR) has faced severe drought over the last three decades, which led to a significant decline in land productivity, posing considerable threat food security and local economy communities. United Nations Convention Combat Desertification (UNCCD) proposed use of Earth observation-derived vegetation indices for monitoring degradation across regions. In this study, we...

Land is both a source and sink of carbon dioxide (CO2), the chief greenhouse gas. Through sustainable land management (SLM), it can capture extra CO2 store as in vegetation soil. SLM also reduce emissions from land. Thus, viewed key land-based solution for climate change mitigation. Yet, provides effective (CC) adaptation practices—such agroforestry, mulching water harvesting—which confer resil...
