Estimation of water demand

  • Cropping patterns: Before and after
  • Crop income: I = f(y)
  • Farm budget
  • Market prices are used for determining the income from crop yield
  • Water requirement for crop: the additional water should be supplied until marginal physical product (MPP) is reduced which is economically profitable.
  • MPP = Marginal benefits/Marginal costs

 

Criteria for water charge

  • Cost of construction
  • Ability of Farmers
  • Benefits derived from irrigation
  • Running cost
