building resilience in managing fresh water Fred Boltz, Ph.D. COP18 Mountain Day
climate adaptation is most urgently about fresh water security
rapid climate change in the world’s water towers Nature 2008
degradation of freshwater ecosystems
fragmentation 2/3 of large river systems moderately or highly fragmented by dams and reservoirs
1890–1922 climate-infrastructure mismatches Dave Meko, Laboratory of Tree-Ring Research, University of Arizona. most infrastructure and water resource management has been designed for a single climate
climate-infrastructure mismatches • infrastructure has a climate-relevant lifetime • if designed for a narrow operational window, it is likely to lose efficiency • adaptability, multiple climate futures must be considered
basin-wide threats to food security
threats to energy security
Ethiopia: one drought lowered growth rates over a 12-year period by 10%; droughts normally happen every 3 to 5 years threats to economies Sadoff & Muller 2009

conserving natural ecosystems is key to freshwater resilience Timing
building resilience into infrastructure • designed and managed flexibly, for shifting ecological and economic conditions • ecologically viable over an operational lifetime (or longer)
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
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 enabling dynamic operational decisions, policies and investments
