Why water policy?

  • Reducing sediment loads
  • Regulating the timing of water flows (wet and dry seasons)
  • Increasing the volume of water
  • Improving the quality of available water for domestic use
  • Enhancing eco-tourism
  • Generating power supply
  • Using a means of transport
  • Using for irrigation
  • Using for industrial use

 

Water in food production

  • In this world, agriculture uses 69% of water resources, 23% by industr and 8% by households.
  • In developing countries, the water for agriculture accounts for 90%.
  • Globally, 90% of the increased food production in the next 25 years is expected to cone from already utilized area.
  • The main challenge of the future is to achieve “more crop per drop” by raising water productivity and avoiding mismanagement. In arid regions water can be imported as virtual water.

 

 

Watershed Protection

  • Environmental problems that contribute to watershed degradation include inappropriate farming practices and massive deforestation.
  • Appropriate strategies for upland areas require greater emphasis on generating the site specific recommendations which should focus on low cost methods of soil and moisture conservation.
  • Adoption of vegetables and cultural techniques for soil conservation is rather than river training in sustainable measures of watershed protection.
