Impact of Climate Change on Water Quality and Sustainability in Baluchistan: Pakistan's Challenges in Meeting United Nations Sustainable Development Goal (UNSDG) Number 6

Pakistan's water quality and water management are at a crucial juncture, especially in the underdeveloped province of Baluchistan. The fifth most populous country, which ranks fifth in the global climate vulnerability index, confronts evolving water security challenges, which are complicating its national security matrix. Water shortages are escalating swiftly due to increasing demand across all sectors that utilize water. The burgeoning population, increasing from 175 million in 2010 to an estimated 247 million in 2025, and the adverse impacts of climate change are seriously affecting water quality and availability. This is exacerbated by persistent political instability and internal security issues, disincentivizing potential investors in the water sector in Pakistan in the short to medium term. The quality of water for drinking purposes is declining fast due to scarcity and contamination from various sources. The political promise of ensuring safe drinking water for the residents of Baluchistan remains an election slogan due to the persistent disparity between promises and implementation. The study involves a physical examination of water samples collected from various sectoral geographical zones of Baluchistan in the laboratory testing process to ascertain the quality of water. To develop a comprehensive picture, the samples were collected from both rural and urban areas in designated zones, ensuring that samples were representative of the entire province. In the last stage of the investigation process, the sample results have been compared with minimum safe standards instituted for drinking water by national and international organizations. Laboratory testing results indicate a significant decline in the quality of drinking water in Baluchistan; in most cases, the samples could not meet the permissible safe ranges outlined in Pakistan's National Quality Standard (NQS) framework for drinking water and WHO guidelines. The persistent decline in water quality and water availability poses serious challenges to the attainment of UNSDG number 6 regarding the provision of clean drinking water to the inhabitants by 2030. The study provides incisive analysis and actionable recommendations as a policy input to facilitate relevant ministries and organizations in mitigating the vulnerabilities of climate change, providing clean drinking water to inhabitants of Baluchistan, and addressing critical issues of water sustainability in Baluchistan as an evolving national security challenge.
