•designed and managed flexibly, for shifting ecological and economic conditions
•ecologically viable over an operational lifetime (or longer)
building resilience into infrastructure
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
