EVALUATING REMOTE SENSING TECHNIQUES FOR MONITORING GRASSLAND DEGRADATION

Caminhos de Geografia
Ecosystem degradation is one of the most significant environmental challenges worldwide. In particular, grassland degradation poses serious threat to agricultural productivity, species diversity, and soil stability. This study aimed to compare the applicability of two remote sensing techniques – the Linear Spectral Mixture Model (LSM) and the Grassland

Land parcellation reduced spatial redundancy resulting in grassland degradation

People and Nature
Degradation is the most immediate threat to biodiversity and sustainable livelihoods of global pastoral grasslands. However, we are still uncertain why grassland degradation is enhanced by the land policy of grassland parcellation.
