  8. Value natural infrastructure by investing... ... to secure, improve and restore the considerable multi-functional value of biodiversity and ecosystems to provide food and energy, conserve water, sustain livelihoods and contribute to a green economy while strengthening the basic role that nature plays in supporting life, well-being and cultures. Available water resources Ecosystem function

  9. Consensus building on better practice • How to... • optimise dam operations and water infrastructure • include built and natural infrastructure options • improve benefits to people, nature and sustainable economic development • enhance water, food and energy security Bonn2011 Commitment A ‘Nexus Dialogue on Dams and Water Infrastructure Optimisation’

  10. Global dialogue platform 3. Policy dialogue & coherence strengthened across sectors 4. Solutions & innovations disseminated & communicated 2. Consensus on best practice improved 1. Knowledge, know-how, experience & tools shared

  21. Group 1.Nexus infrastructure and technology • 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? • 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 • Are there barriers in governance to working across water, energy food sectors in transboundary basins? • How can governance challenges due to multisectoraldemands be addressed through the TDA SAP process (e.gInterMinsterialcommittees that have water, energy and food sectors)? • 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 • 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? • What economic tools and incentives can be used to induce cooperation across sectors at the transboundary level?
