### **4. Conclusions and Recommendations**

Water demand is increasing with increasing population, economic growth, urbanization, industrialization, and climate change. Water demand for the Sahiwal district was found to be at the maximum because it has the largest land use area for crops. Unmet demand was found to be the highest for the districts of Sahiwal and Khanewal. WEAP is user-friendly and can be used easily for the evaluation of different water managemen<sup>t</sup> strategies and policies before implementation. The constraints faced include the unavailability of institutional support, sufficient and reliable information, and political conflicts.

To meet the unmet demand, protect the groundwater resource from deterioration, and mitigate the effects of climate change, the water should be supplied on a demand basis rather than a supply basis. The wastewater can be treated and then can be used for irrigation purposes. This can help to reduce the irrigation demand, changing the cropping pattern and the use of water-efficient crops in the districts of Sahiwal and Khanewal can reduce the water demand in these areas. Efficient irrigation methods such as sprinklers and drip irrigation can also help in reducing water demand. The domestic demand can be reduced by maintaining a low population growth rate and using water-efficient taps in the houses. Consumer education and awareness level may affect water use and practices, which could result in water demand reduction. WEAP is user-friendly and can be used for identifying the impact of different water managemen<sup>t</sup> strategies and policies.
