MOSA - Integrated water resources management: Middle Olifants South Africa


Water resources management; Water policy, South Africa, virtual water trade; water market, water quality, water allocation, water scarcity


South Africa


  1. Investigate policy instruments and organizational settings that improve water allocation and reduce water pollution
  2. Identify and assess the transaction costs inherent to the implementation of water policy in considering heterogeneity between water users (farmers, mines, households).
  3. Determine the marginal values of water in different sectors (agriculture, industry, services) and assess the impacts of water use on water quality for different locations and times in the Olifants basin?
  4. Evaluate the costs and benefits of water treatment and assess the potential for addressing water scarcity through virtual water trade

Hydro-economic; econometric analysis and field research, expected utility theory, economic of transaction costs and multiple choice modeling
