Advantages
- 40 percent more land in Pakistan has become available to farm, which has increased food security
- over 14 million hectares of land is now irrigated
- a larger variety of crops can be grown, and yields have increased - which means that diets have improved and some farmers have cash crops
- similarly, diets have improved as fish are farmed in some areas, which is a good source of protein
- and with more cash crops (spare crops that can be sold), the agricultural industry has grown and can now contribute more to the GDP/GNI of the country, boosting the national and regional economy

Disadvantages
- some farmers are greedy and take too much water - this deprives others of it, and is unfair as this means that some people still struggle when they shouldn't have to
- climate - high summer temperatures result in a high rate of evaporation which could lead to salinisation, and means that there's less water for distribution at that time of year
- a lot of water is lost or wasted due to poor irrigation techniques, and salinisation is becoming a problem, and can potentially cause loss of soil fertility
- high costs - the maintenance as well as construction
