Description | Comments | |
---|---|---|
Scenario 1 | Linear reduction of freshwater availability by 25% in all considered regions | This reduction is supposed to be linear across all (districts) regions of the country |
Scenario 2 | Linear reduction of freshwater availability by 25% and increase of irrigation water use efficiency by 10% | Improvement of IWUE in ASMOT is simulated by decreasing water volumes required by crops/systems by 10% |
Scenario 3 | Linear reduction of freshwater availability by 25%, increase of irrigation water use efficiency by 10% and higher producer prices offered to farmers. The suggested increase of producer prices are as following: + 10% for fruits and vegetable prices and + 5% for cereal prices | Cereal prices are mostly fixed by the government and change slightly across years. However, fruits and vegetables are commercialized in a free market, and prices received by farmers are very low compared to consumer prices. Better integration of farmers in value chains may reduce this gap |
