Water is essential not only for sustaining quality of life on the earth, but also for economic growth and poverty eradication. Due to rapid increase in population, the demand for water will increase over time. The nations that are well endowed in fresh water resources have an economic advantage over those less fortunate. Water resources management is a cost effective strategy; contributing to the economic prosperity and poverty reduction through several pathways, while strengthening systems and capacity for longer-term climate risk management. The access to safe and adequate water improves health, fulfills multiple needs of households, contribute to food and fiber production and poverty elimination. The prime purpose of present paper is to enhance the understanding of the factors that influence water demand by deeply examining the water use in domestic, agricultural and industrial sectors in Pakistan. The driving forces and key issues, related to socio-economic development, that influence the future water availability and demand are also examined. Pakistan is a country that is facing a water crisis not because of physical scarcities of the resources, but because of lack of knowledge, experience, technology and co-ordination among different institutions. The empirical evidence shows that better management coupled with effective policy, intensified political will, appropriate investments, awareness, climatic change adoption and institutional strengthening are promising pathways for sustainable water resources management. In order to meet the water demand for environment, economic and people's life, there is scope for significant improvement in the efficiency of water utilization, which if achieved should enhance the overall sustainability. |
