  1. Energy in a Water Constrained World Dr. Joerg Hartmann WWF Dams Initiative Leader

  2. Whyis WWF concernedwiththis? • Risingenergydemand and shifts in energy mix • Growingimpactson water from hydropower dams, coolingwaterfor thermal and nuclear, waterabstractionforbiofuels etc. • Bothnon-consumptive and consumptivewateruses • Energyisonesectorcontributingto massive losses in freshwaterbiodiversity and ecosystemservices

  3. Oneindicatorofpressurefrom energy on water

  4. Resource assessment and prioritization (including ecological and social resources) Conservation and efficiency options Hydropower generation target Non-hydro generation targets Project-level EIA Designation of protected rivers and basins Project-level review, mitigation and development Basin approach to hydropower development Regional energy planning Assess energy needs and compare alternatives across relevant energy market Strategic Environmental Assessment Water management (water supply, irrigation, flood control, navigation, recreation etc.) Integrated Basin Planning Source: TNC

  5. Advantages ofBasin Approach For society: • Allocation of water resources to highest-value use (→IWRM) For hydropower investor: • early identification and avoidance of potential risks such as: - hydrological risks from increased water demand and abstractions upstream of the site; - market risks from other energy sources or demand management strategies; - operational constraints from downstream water uses; - delays in implementation due to complex permitting procedures, reluctance on the part of financing institutions, conflicts with local stakeholders etc.

  6. WWF Position on Hydropower • Committedto an expansionofsustainable hydropower • Estimate: additional 400 GW globallyby 2050 • Definition ofsustainabilitynot just project-level – hastobebased on comprehensiveplanningtodetermineneedsand options

  8. Key messages • Promote good water resource management, as this will increase the resilience of our hydrological systems to multiple, interrelated challenges - climate change as well as growing energy and food demands. • IWRM is imperative to ensure compatibility of different demands on water. In water-scarce basins, energy options will be determined and constrained by current and future availability of water – like it or not. • Limit ecosystemimpactsofenergyinvestments – bothattheproject and atthemacrolevel.Shiftto a low-water-footprintenergy mix.
