Describe the surface and groundwater resources in Pakistan

Model Answer

1. Pakistan's water resources are divided into two main categories: surface water and groundwater. Surface water is found on the Earth's surface in rivers, lakes, dams, reservoirs and canals, while groundwater is stored beneath the surface in underground aquifers.

2. The Indus River System is the largest source of surface water in Pakistan. It includes the Indus River and its tributaries such as Jhelum, Chenab, Ravi, Sutlej and Kabul, which provide water to different regions of the country.

3. Pakistan's extensive canal irrigation system distributes river water to agricultural lands. It supports the cultivation of important crops including wheat, rice, cotton and sugarcane.

4. Major dams such as Tarbela and Mangla store surface water for irrigation, control floods and generate hydroelectric power, contributing to energy production and economic growth.

5. Groundwater is obtained through tube wells, wells and hand pumps. It is an important source of water in areas where surface water is unavailable or insufficient.

6. Water resources support industrial development by providing water for manufacturing processes, cooling systems and other industrial activities.

7. Rapid population growth, climate change, pollution and excessive use of water are creating challenges for Pakistan's water resources. Poor management can lead to water shortages and environmental problems.

8. Therefore, sustainable water management, conservation practices and efficient use of both surface and groundwater resources are necessary to ensure Pakistan's agricultural productivity and future economic development.
