Abstract
Abstract The multiple effects of ecosystem restoration programmes deserve attention. After reviewing the social‐ecological effects of 23 ecosystem restoration programs in Asia's drylands, we find that these programmes mainly contribute to sustainable development goals (SDGs) synergistically, but the trade‐offs between social‐ecological effects still exist. Among the five goals of SDG15 (Life on Land), SDG13 (Climate Action), SDG6 (Clean Water and Sanitation), SDG1 (No poverty), and SDG2 (Zero Hunger), 11 programs can synergistically achieve no less than three goals, especially grassland restoration and water diversion in China, as well as water management programmes in Israel. However, the contribution of ecosystem restoration programs to SDG15 easily weakens SDG6, SDG1, and SDG2, indicating the competition of land and water between ecosystem restoration and agriculture. To reduce the trade‐offs among SGDs caused by ecosystem restoration, we propose the social‐ecological system research framework of 'Dryland Boundary – Water, Food, Energy and Ecosystem Nexus – Meta‐coupling – Nature‐based Solutions' to guide the implementation of ecosystem restoration programmes from four aspects: supply–demand matching, element matching, regional matching, and local adaptation.
