Water protection, food production, and ecosystem health are worldwide issues, and understanding the links between water, food production and ecosystems is important to the health of all three. This book shows how sustainable ecosystems are essential for water management and food production. It covers food security, the challenges and management of agroecosystems, and how to increase water productivity in agriculture. Including the reversal of land degradation and how to tackle water scarcity, it examines ways to balance increasingly intensive agriculture with ecosystem enhancement and protection. This books also reviews the important two-way relationship regarding the impact that agriculture can have upon an environment and the importance of ecosystems in supporting water for agriculture.
