  • Nexus Dialogue on Dams and Water Infrastructure Optimization - A Global Platform for Promoting Implementation of Best Practices of Large-scale Multipurpose Infrastructure (Nexus Outcome Initiative). Mr. Julien Katchinoff, US Dept of State, USA
  • Global population isbecoming increasingly urbanUrban population is projected to increase by 2.9 billion, to a total of 6.3 billion in 2050Today, one in two people on the planet live in a cityEvery second, the urban population grows by 2 people
  • Trends in global water use by sectorNearly 80 percent of the freshwater resources available to people around the world are used to grow food (grey band represents difference between amount of water extracted and that actually consumed). We need to look at how to improve water delivery Precedents have shown that the simultaneous analysis of water and energy use at the policy level significantly increases productivity in the use of both resources. Taking full account of approaches to energy efficiency during water policy decisions can lead to substantial energy savings, and vice versa.For example Nairobi lost 10% of its GDP during a 2008 drought because of lack of water availability. Tunisia, however, which experiences more sever droughts, have diversified their sources (groundwater, desalination, inter-annual storage) and thus have decreased risk and do not experience these fluctuations in GDP
  • 2050 – The ChallengeThe world population is predicted to grow from 7 billion in 2010 to 9.1 billion in 2050. Water: Demand projected to increase by 55% more than current levels by 2050 (OECD Environmental Outlook to 2050)Energy:Demand projected to increase by 80% more than current levels by 2050 (OECD Environmental Outlook to 2050)Food: Demand projected to increase by 60% more than current levels by 2050 (FAO:TOWARDS 2030/2050) As global populations continue to grow, development of innovative water infrastructure and technology that optimise and address the interdependencies of water, energy and food (i.e. multi-purpose reservoirs for agricultural irrigation, domestic water supply and hydropower) will become ever more important.This population increase will need to be serviced with water, energy and food against a backdrop of climate change.
  • Climate ChangeLatin America and the Caribbean (LAC) are particularly vulnerable to the observed and projected impacts of climate change because of its geographic location and reliance on natural resources for economic activities and livelihoods. Key impacts in the region by or about 2050 include the forecasted collapse of a significant portion of the coral biome in the Caribbean, disappearance of most glaciers under 5000 m in the Andes, the likelihood of some degree of savannization in the Amazon basin, reduction in agricultural yields of many staple crops, increased flooding and inundation of coastal zones, increased exposure to tropical diseases, destabilization of the hydrological cycle in major basins, and the intensification of extreme weather events.Estimated annual damages in LAC caused by the physical impacts associated with a rise of 2oC over pre-industrial levels are estimated to be of the order of over $100 billion, or about 2% of current GDP . Losses of this magnitude would limit development options as well as access to natural resources and ecosystem services. More worrisome is the fact that many of these changes are irreversible, committed, and therefore will continue to impact the region over the long term. Conversely, overall costs to adapt are estimated to be on the order of 0.2% of GDP for the region, or about 10% of the costs of physical impacts, indicating that adaptation is generally very cost-effective.
  • Interactions with thehydrological cycleOur interactions with the hydrological cycle are increasing in complexity – which offer potential opportunities and challenges
  • shrink – add KM from Bonn: then where does nature and NI fit in the nexus – modify diagram
  • follow up to Bonn commitmentannouncement: preparing to launch; partnership with DOSwhy and why now?goalwhy a nexus focus? –the opportunities, moving to optimisation
  • The IUCN Nexus infographicAsk the questions on the slide
  • Expected resultsplatform concept: what makes it a platform?
  • activtiestimelines with key stepsadd participation track and contrinutions expected/needed
  • Conventional linear approach - supply it, use it, treat it, and dispose of itMany river basins and catchments are experiencing demands for water exceeding available supplyHow do we move from a linear throughput approach to a closed loop systems ‘nexus based approach’ (e.g. resource recovery)?
  • What do “resource recovery” processes look like? What role does technology and infrastructure play and what limits will be imposed? These challenges are big and no one entity can do everything but everyone can do something Steps can be taken now to place us firmly on an alternative to the “business-as-usual” path
  • Enables IUCN and IWA to be active in the water - energy – food nexusConnects ‘problem owners’ with ‘solution providers’Catalyses country / river basin level action to better target investments

    20. 20. Group 1.Nexus infrastructure and technology 1. Do you know of examples of infrastructure (built and natural) and technology for sharing water resources across the water-energy-food nexus in transboundary basins? 2. What are the obstacles and enabling factors for built and natural infrastructure to sustain water, energy and food security as well as maintaining functioning ecosystems? Group 2. Nexus governance and partnerships 1. Are there barriers in governance to working across water, energy food sectors in transboundary basins? 2. How can governance challenges due to multisectoral demands be addressed through the TDA SAP process (e.g InterMinsterial committees that have water, energy and food sectors)? 3. What new collaboration platforms can IW Projects think of to bring in energy and agriculture? And what technical expertise or tools are required? Group 3. Nexus economics and financing 1. How can basins (with GEF support) leverage private and/or public finance across the water, energy and food sectors to finance SAP investments focusing on enhancing and/or maintaining ecosystems services? 2. What economic tools and incentives can be used to induce cooperation across sectors at the transboundary level?
