  5. 5. 1. Water Security = A Global Concern The challenge of securing safe and plentiful water for all of us is one of the most daunting challenges faced by the world today… Our experiences tell us that environmental stress due to lack of water may lead to conflict and would be greater in poor countries UN secretary-General Ban Ki-moon WEF, 24 Jannuary 2008 Humanity is facing « water bankrupcy » as a result of a crisis even greater than the financial meldown now destabilizing the global economy … it is already beginning to take effect, and there will be no way of bailing the earth out of water scarcity … G. Lean, The Independent, 15 March 2009
  6. 6. 2. The Global Climate Challenge = A Global Water Challenge Warming and Water Availability •Higher temperature → less ice - Snow-pack loss → changed runoff timing -Reduced permafrost, seasonally frozen soil → activation of subsurface storage •Higher temperature → more water in atmosphere (7% per degree C) → global redistribution of precipitation and runoff

  14. 14. 3. Water Security = A Framework for Adaptation Water Security = { Reliable Availability + Acceptable level of Risks} A focus on water security provides a framework for developing appropriate response strategies Much of the challenge focuses on managing hydrological variability -- economic impacts of variability today are far-reaching, and climate change will increase such variability The scale of the water security challenge depends on a basin’s natural hydrology, and countries’ mix of institutions and infrastructure for water management
  15. 15. 3. Water Security = A Framework for Adaptation Implementing IWRM supports Adaptation Planning at the river basin level Strong intersectoral cooperation Managing trade-offs Good governance
  16. 16. 4. A Better Future = Collaborative Adaptation Type of Cooperation The Challenge The Opportunities Increasing the benefits to Degraded water quality, Improved water quality, river the river watersheds, wetlands, and flow characteristics, soil biodiversity conservation, biodiversity and overall sustainability Increasing benefits from Increasing demands for Improved WRM (Agri the river water, sub-optimal WRM-D +hydrop) flood-drought management, navigation,environmental conservation, water quality and recreation Reduced costs because Tense regional relations and Coop&Dev < of the river political economy impacts Dispute/conflict, food/ energy selfsufficiency > security, .. Increasing benefits Regional fragmentation Integration of regional beyond the river infrastructure, markets and trade C.W. Sadoff, D. Grey / Water Policy (2002)
  17. 17. 4. A Better Future = Collaborative Adaptation Transboundary cooperation is both necessary and beneficial in adapting to climate change Barriers to collaborative adaptation in the legal, institutional and policy spheres should be removed When planning for adaptation across boundaries, riparian countries should focus on transboundary impacts, sharing benefits and risks in an equitable and reasonable manner Sharing information, including that from early warning systems, between riparian countries is essential for effective and efficient climate change adaptation
  18. 18. Conclusions The international rivers of the world are coming under growing pressure from climate change Water security as a framework of adaptation can be achieved on the basis of « hydrosolidarity » which embraces collective action, interdependence, and shared responsibility The approach to collaborative adaptation is IWRM supported by strong management institutions, a high level of cooperation among all interests and continuous adaptation to new conditions If the focus from competing national interests can be shifted to attaining common benefits, genuine transboundary water security can be achieved and sustained
