How arid is the lower Indus Basin – what does the average farmer experience?
What are the practices (adaptation/strategies) to this inadequacy poor timing of supply
1. Cultivate and irrigate less than the entire area – cropping intensity <100% in each season;
2. Cultivate some of the area with crops requiring less water – crop diversification;
3. Allow crops to undergo water stress and accept a decrease in yield – deficit irrigation; and
4. Use groundwater to supplement surface (canal) water – conjunctive water use.
Are we doing enough? – Probably not
• Too little, too slow
• Significant population pressure
• Climate change
• Land degradation
• Socio-economic changes including urban migration
• Business-as-usual approach
• Youth unemployment
