  • 1. An Ecosystem Approach to Provisioning services Regulatory services Supporting services Cultural services Water and Food Security • Increase diversity within cropping system Eline Boelee (Water Health/IWMI), Elizabeth Khaka (UNEP), Gareth J Lloyd (UNEP-DHI) • Select appropriate varieties Simon Cook (CRP Water, Land and Ecosystems), Sara Scherr (Ecoagriculture Partners), Thomas Chiramba (UNEP), Nick Chudeau (UNEP) • Increase productivity/area IWMI is a member of the CGIAR Photo: Karen Conniff Consortium U NE P and leads the:Recognizing the multiple functions of agroecosystems and the many services they provide is essential to fostering an integrated ecosystem • Integrated feed management strategiesapproach to natural resources management, agricultural production, and food security. The services provided by natural and 1agroecosystems can be optimized through appropriate land use planning that takes into account the limits of each ecosystems • Water management 2carrying capacity. Thus food production can be made more sustainable; more productive by producing more food, services, and benefits 3per unit of land and water ; more resilient to climate change and other shocks; and more compatible with sustaining other ecosystems • Increase productivity/animal 4with their functions and services.
