  1. Climate change and the Israeli Water Sector TA - Uni Miki Zaide Israel Water & Sewage Authority February 18 2010

  2. Main water management challenges Water supply - the extent of water shortage Israel: available fresh water 1,200 mcm/year; current population ~7.5 million  160 m3/y/capita This is about 30 % of “Shortage Red Line” as defined by the UN

  3. Replenishment Data (Three Basin System) 1932-2009 1993-2009 Average replenishment dropped by ~10% Cumulative shortages associated with sequences of dry years require reliable additional supply

  5. Table 2: Summary of the climate, Hydrological, evaporation and salinity concentration models and the effect on water availability in Lake Kinnert * Outflow is equal to inflow, no unnatural salt removal from the lake is taking place.

  6. Main water management challenges for the Israeli water sector • Governance: Management of the water sector • Water supply of several types (quantity and quality) • Preservation & rehabilitation (?) of the natural water resources • Transboundary water issues • Preserving nature and ecological systems • External threats & uncertainty (e.g. climate change) • Water sector efficiency (e.g. regulation, water tariffs)

  7. Scenario building • Building basic scenario (Business as usual) • Mapping possible scenarios • Choosing the specific weight of each scenario
