Constructing semi-arid ecological barriers to prevent desertification
-
ABSTRACT
Semi-arid regions worldwide face escalating challenges, including water resource shortages, ecological fragility, and relentless expansion of desertification. Here, we propose the establishment of a worldwide Semi-arid Ecological Barrier (SAEB) as a proactive measure in response to these challenges to curtail desertification and alleviate extreme events. Beyond its immediate benefits, the SAEB holds significant promise for future global carbon control efforts. This perspective offers a case study exemplifying the principles of ecological civilization, focusing on preventing desertification in the Yellow River Basin. Policy of ecological recover, such as the “Grain for Green” project in China, has shown to be effective in strengthening the SAEB. It contributes valuable insights into innovative strategies for addressing water scarcity, ecological fragility, and desertification expansion. -
