Abstract:
The Water-Energy-Food-Climate (WEFC) nexus demonstrates a vital, interconnected framework that supports both environmental integrity and socio-economic well-being. In nations such as Pakistan, the interplay of development challenges, population growth, resource scarcity, and climate change necessitates a focused approach to address this complex relationship, which is vital for achieving long-term sustainability. This thesis explores the intricate relationships among water, energy, food, and climate change, with a particular emphasis on Pakistan's capacity to address these challenges in pursuit of socio-economic development and national security. Pakistan, characterised by its primarily agrarian economy, relies significantly on the water resources provided by the Indus system, with the agricultural sector being the largest consumer of this vital resource. Nonetheless, the challenges posed by water scarcity, ineffective irrigation methods, and the worsening effects of climate change jeopardise both food and water security. Moreover, the energy crisis in Pakistan, intensified by reliance on imported fossil fuels, adds another layer of complexity to this matter. Because of this lack of recognition of their interdependence, most previous studies have treated these areas independently. This disjointed method has impeded the progress of cohesive policy solutions. Therefore, this thesis aims to connect the interrelated aspects of water, energy, food, and climate. It will examine the obstacles to effective policy coordination and emphasise the potential for developing a more sustainable and resilient model for the future. This study offers a critical evaluation of the effectiveness of Pakistan's existing policies, which tend to be predominantly sectoral and lack the essential integration needed to address the interconnected issues in a comprehensive way. Furthermore, it examines the importance of collaboration across different sectors and suggests a framework for integrating the management of these areas to improve resource utilisation, enhance policy alignment, and bolster Pakistan’s resilience to climate change.
