building (human) resilience in fresh water management• integrate ecosystems into adaptation
• smart development: design new infrastructure to maintain environmental flows and ecosystem connectivity
• approach vulnerability assessment and reduction as a continuous, adaptive process: -- for ecosystems, infrastructure, and institutions

enabling dynamic operational decisions, policies and investments• AGWA aims to integrate
disciplines to facilitate the adoption of climate-adaptive best practices
• WCC mainstreams science and management guidance into global policies for effective freshwater adaptation
