SCALE—System-wide Collaborative Action for Livelihoods and the Environment—is an approach for broadening development impact. By providing a framework to achieve widespread change, SCALE can help improve people’s livelihoods and quality of life by helping them manage their natural resources in a sustainable way. SCALE has evolved from more than a decade of work by GreenCOM, a U.S. Agency for International Development global environmental communication program. GreenCOM has had the unique opportunity of working with people in more than thirty countries around the world to address an extensive range of issues including: 􀂄 Natural resource management (coastal, forest, watershed); - Biodiversity conservation; - Ecotourism; - Sustainable agriculture; - Water and energy efficiency; - Clean production; and- Solid waste management.
