    Drought Risk Assessment Drought Risk Assessment Presentation Transcript

      • Hydro-Climatic Disasters in Water Resources Management
      • 30 Nov - 02 Dec 2009, Georgetown, Guyuna
      • Explain the occurrence, impact and management of the drought phenomenon
      • Understand types, factors, indicators of droughts
      • Understand intensity, frequency, severity, and risks associated with droughts
      • Establish a basis for drought management
      • Drought is normal, recurrent feature of climate
      • Occurs almost everywhere, although its features vary from region to region.
      • Defining drought depends on differences in regions, needs, and disciplinary perspectives.
      • Cuts across many sectors
      • Cuts across normal divisions of responsibility of local, state, and federal agencies
      • Heightens food insecurity
      • weakening capacities for delivery of critical services
      • Examines the consequences of a given event or change,
      • Begins by identifying direct consequences of the drought, such as reduced crop yields, livestock losses, and reservoir depletion.
      • Direct outcomes can then be traced to secondary consequences (often social effects)
      • Require strong political commitment, community participation, and consideration of local realities
      • The international and regional communities also play an important role in coordinating activities, transferring knowledge, supporting project implementation, and facilitating effective and affordable practices
      • Is there capacity to monitor and analyze drought events ?
    • Sector Impacts Food security outlook in the Horn of Africa region in 2005
      • How and when is information drought communicated to those at risk?
      • Severe drought is often slow in its development, it is relatively easy to tell when one is coming
      • Put in place a system for monitoring , early detection and response to drought impacts threats
      • Mitigation is through soil and water conservation
      • Regulate public use of water
      • Improve alternative/ contingency water sources e.g. desalination of seawater, water recycling, and enhancing rainwater harvesting
      • Extensive monitoring of precipitation and water usage are the best way to prepare for a drought
      • Contingency measures for impacted sectors
    • (Courtesy of USDA–NRCS)
        • Furrow Dike Holding Water
        • Laser controlled land levelling
      • In 15 minutes
      • Take a card
      • Put down 2 or 3 points for each question below;
        • What is the implication of drought problem in your country
        • What changes are required for more effective drought management
