Solutionstake home messages
• Water is a primary medium through which early climate change impacts will be felt by people, ecosystems and economies
• The core challenge of adaptation is water security: ensuring the ability to harness water’s social and productive forces and control water’s destructive forces
• Proactive water management is proactive adaptation -- in the same way that a strategic energy policy is the key to mitigation

Actions will need to:
• balance the three Es
• take place at all levels -- projects, villages, economy wide, global
• involve both software and hardware
An integrated approach is therefore crucial

• The physical science -- impacts on hydrology
• The broader dynamics
• Timeframes, sequencing and uncertainty

Impacts on hydrology
what are the challenges?
what can be done?
Solutionstake home messages
framing the issue
rainfall, runoff and
streamflow – floods and
droughts, more intense and
more frequent storms
temperature – aridity,
evaporation, glacier and
snow melt, loss of storage
sea level changes -- impacts on estuaries,
deltas, and groundwater
intrusion

The broader dynamics
what are the challenges?
what can be done?
Solutionstake home messages
framing the issue
Changes will affect demand for water
Changing availability, timing and certainty of water will play out in all water-using sectors – agriculture, hydropower, water supply and sanitation, the environment…
Changes will also affect the broader dynamics of the economy – water scarcity, water related disasters, spatial patterns of development, structural changes in economies
Adaptation means managing these dynamics

The temporal dimension: timeframes, sequencing and uncertainty
what are the challenges?
what can be done?
Solutionstake home messages
framing the issue
Impacts are in the future, uncertainties
are great
Some responses are particularly long-lived
Timely now to focus on strengthening management, information, infrastructure

Solutionstake home messages
• Strengthen institutions, information and capacity to predict, plan and cope with today’s climate variability
• Actions will need to take place at all levels, from villages to projects to economy wide to global
• Guided by science and best practices
• Balance software and hardware• Balance the 3 Es

framing the issue
• Risk management• Information and cooperation• Also water quality! Must understand
these dynamics• Water rights and allocation
mechanisms in the face of new realities• Rethinking water storage – natural,
man-made, virtual• Adaptive management – building
dynamic organizations

Financing adaptive WRM
• Why should poor countries address tomorrow’s climate change if they cannot afford to manage today’s drought?
• Some principles of adaptation financing
• WRM investments should be viewed as sustainable development financing that delivers adaptation benefits

Final take home messages
1. Adaptation is about water security – an important goal today, and a stretch goal for tomorrow
2. Water security is about good water managementMix of soft and hard, enhanced information & cooperation
3. Water management is a fundamental adaptation strategyToday’s investments in water security should be explicit part of coherent strategy for adaptation
