A catchment-based and integrated approach to land use, water, and ecosystems will be essential for a knowledge-based balancing of water among different ecological processes and the provision of ecosystem services. It will be necessary to develop the scientific and administrative capability and capacity to analyze the conditions necessary for securing social and ecological resilience to change in ecosystems, including in those that are par- ticularly vulnerable to large or episodic events, such as drought, storms, and floods, and those that are subject to multiple and cumulative impacts. Climate change raises questions about how the future use of water and land for agriculture will constrain the ability of eco- systems to respond. at is, will water and land uses adversely affect ecosystem resilience and responses to climate change?
We are dependent on the ecological components and processes and ecosystem servic- es that provide or support much of our food. us a more cautious approach toward water management and food production will be essential to ensure social and ecological sustain- ability. While food production will continue to be at the forefront of our endeavors to support human well-being, sustainability can be achieved only through a more conscious striking of tradeoffs between different interests. Underlying all must be a clear understand- ing of the vital role that ecosystems and ecosystem services play in supporting human well- being and the recognition that much past ecological change has undermined the provision of many vital ecosystem services, often with complex social and economic inequities.
