Intended Learning Outcome After completion of this module the participants will be able to…

  • describe and compare measures to cope with water scarcity and drought
  • by quantifying and assessing causes and impacts of climate variability and change on water security
  • in order to develop drought risk and water efficiency strategies and plans at a regional level.
Content Understanding Scarcity and Drought

  • Spatio-temporal variability of climate parameters, dimensions of water scarcity, classification of droughts
  • Overarching principle of reaching “Water Security”
  • The use of indicators and indices.
  • Analyze and quantify drought hazard, vulnerability and risk
  • Analyze and quantify impacts of climate variability and change on water availability and hydrological extremes

Coping with water scarcity

  • Overview of strategies: conservation, allocation, new sources
  • Conservation potential in agriculture, loss reduction in public networks
  • Water allocation principles and to cope with scarcity at river basin level
  • Rainwater harvesting, managed aquifer recharge and other storage options

Coping with droughts

  • Drought monitoring and early warning
  • Drought modeling
  • Develop drought risk management strategies and plans (water allocation plans; structural and non-structural measures, early warning etc).
Teaching Method Input lecturesSelf-study, group discussions, presentations to class, Exercises: calculating drought indices, methods of drought vulnerability assessment, technology options to conserve water, setting up drought risk management plans
Assesment Method scientific paper on a selected topic regarding drought assessment or management (written report 100%)
