Disentangling the potential of protected areas to promote sustainable development
Protected areas (PAs) and other effective area‐based conservation measures (OECMs) are crucial to sustainable development, yet their contributions to environmental, social, and economic dimensions remain unclear. We investigated the role of PAs and OECMs in advancing the sustainable development agenda by summarizing 400 effect‐size values and measuring
