It then describes outcomes for future ecosystem services under alternative development pathways, with a focus on tradeoffs between food security and the environment, such as implications for fertilizer use, and the role of biofuels. As tradeoffs among various ecosystem services are expected to increase into the future, research will need to focus increasingly on ways to achieve a balance between food security and improving non-food ecosystem services. To reduce adverse future impacts, research is urgently needed in the areas of land use change impacts on ecosystems and biodiversity, mitigation strategies for climate change, enhancing water security, and for hot spot regions where ecosystem services and human well-being are particularly vulnerable, including Sub-Saharan Africa, South Asia, and the Middle East and North Africa region. Key Words: Ecosystem services, food security, tradeoffs, Millennium Ecosystem Assessment Introduction Food supply (and demand) is intrinsically linked with its surrounding environment. The interlinkages among ecosystem services, including the provision of food and water, their future development, and implications for human well-being and food security, were recently assessed as part of the Millennium Ecosystem Assessment (MA, 2003; MA, 2005a). Ecosystem services, which are the benefits people obtain from ecosystems, include supporting, provisioning, regulating, and cultural services. Supporting services include nutrient cycling, soil formation, and primary production. .
