  2. 2. <ul><li>Explain the occurrence, impact and management of the drought phenomenon </li></ul><ul><li>Understand types, factors, indicators of droughts </li></ul><ul><li>Understand intensity, frequency, severity, and risks associated with droughts </li></ul><ul><li>Establish a basis for drought management </li></ul>
  3. 3. <ul><li>Drought is normal, recurrent feature of climate </li></ul><ul><li>Occurs almost everywhere, although its features vary from region to region. </li></ul><ul><li>Defining drought depends on differences in regions, needs, and disciplinary perspectives. </li></ul>

  5. 10. <ul><li>Examines the consequences of a given event or change, </li></ul><ul><li>Begins by identifying direct consequences of the drought, such as reduced crop yields, livestock losses, and reservoir depletion. </li></ul><ul><li>Direct outcomes can then be traced to secondary consequences (often social effects) </li></ul>
  6. 11. <ul><li>Require strong political commitment, community participation, and consideration of local realities </li></ul><ul><li>The international and regional communities also play an important role in coordinating activities, transferring knowledge, supporting project implementation, and facilitating effective and affordable practices </li></ul>

  11. 22. <ul><li>Regulate public use of water </li></ul><ul><li>Improve alternative/ contingency water sources e.g. desalination of seawater, water recycling, and enhancing rainwater harvesting </li></ul><ul><li>Extensive monitoring of precipitation and water usage are the best way to prepare for a drought </li></ul><ul><li>Contingency measures for impacted sectors </li></ul>
