Agriculture is the backbone of the Pakistan economy. However, water scarcity regularly leads to huge gaps between land usage rates and actual output from farms in the country. Over-usage of water can reduce the amount of crop production almost as a lack of water.
When a country is using its resources such as land and water efficiently, it can easily improve agricultural production. Appropriate quality and quantity of water is significant for the production of crops, livestock and others. It is also very essential for processing and preparation of food.
Effect of climate on water availability:
A change in climate in Pakistan will have an impact on agriculture by increasing the demand of water. It will also limit crop productivity. We are already seeing a greater variation in weather more frequently throughout the growing regions of many countries. Farmers are finding new solutions in regard to water scarcity, but countries that are facing water scarcity need to create strategies that consider long-term water deficits.
Regardless of water shortages, misuse of water is so common. Large cities and industrialized economies are facing this problem due to the mismanagement of water resources.
Dams help to increase water supply:
Dams are basically used to provide a store of water for agriculture and for industrial usage. They can act as an alternative to non renewable energy resources. Dams can help to increase efficiency levels and reduce the environmental damage from weather variability. But this is only possible when water supplies are managed well. Many developing country populations are growing day by day and relying more and more on groundwater resources.
The policy makers must consider actions to save and manage the currently available water and store it in a proper way. Dams should be constructed to deal with the forecasted problems of water shortage and assumed climate risks.
