The Partnership Initiative for Sustainable Land Management (PISLM) is an independent inter-governmental organization dedicated to supporting Caribbean Small Island Developing States (SIDS) in their participation in the United Nations Convention to Combat Desertification (UNCCD). Since its inception, PISLM has been crucial in executing various Global Environment Facility (GEF) projects aimed at sustainable land management. 

Integrated land use management is vital for SIDS due to their limited land space and competing economic activities. Environmental management in these regions is heavily influenced by land resource planning and utilization, which are closely linked to coastal and marine management and protection. The UNCCD provides a global framework for addressing land degradation and promoting sustainable land management, significantly contributing to the Sustainable Development Goals (SDG 15.3), poverty eradication, and food security.
