    • Hydro-Climatic Disasters in Water Resources Management
    • 30 Nov - 02 Dec 2009, Georgetown, Guyuna
  • 2.
    • 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
  • 3.
    • Drought is normal, recurrent feature of climate
    • Occurs almost everywhere, although its features vary from region to region.

    • 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
  • 10.
    • 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)
  • 11.
    • 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

    • 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
  • 22.
    • 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
