Sustainably reducing poverty and improving food and nutrition security are challenges that require coordinated efforts and partnerships between organizations. The partnership between the Economy and Environment Program for Southeast Asia (EEPSEA) and WorldFish supports the sustainable management of natural resources in communities across Cambodia, Indonesia, the Philippines and Vietnam. Funded by the Swedish International Development Cooperation Agency (Sida) and Canada’s International Development Research Center (IDRC), EEPSEA was formed in 1993 with the aim of supporting training and research in environmental and resource economics from which researchers could influence economic policy. EEPSEA supports national and regional environmental economics associations and promotes the exchange of knowledge within the region, while fostering collaboration between environmental economists, policymakers and influencers around the world.
