Climate Diplomacy as a Foreign Policy Tool: Pakistan's Role in Regional Water Politics and Transboundary Environmental Governance

Abstract

Climate change has intensified transboundary water insecurity in South Asia, where shared river systems are increasingly shaped by geopolitical tensions and institutional fragility. This study examines how climate diplomacy, regional water agreements, institutional coordination, and environmental dispute resolution mechanisms influence transboundary environmental governance, with Pakistan as the empirical focus. Based on survey data from 137 policymakers, environmental experts, policy analysts, and academics, the quantitative results show that climate diplomacy, institutional coordination, and environmental dispute resolution mechanisms significantly enhance governance effectiveness, with conflict resolution emerging as the strongest determinant. In contrast, regional water agreements exhibit a positive but statistically insignificant effect, indicating weaknesses in treaty implementation and enforcement. The findings further reveal that Pakistan’s diplomatic engagement capacity significantly mediates these relationships, while geopolitical tensions in South Asia significantly moderate them, constraining cooperative governance outcomes despite formal institutional frameworks. Overall, the study underscores that effective transboundary water governance depends not only on formal agreements but more critically on diplomatic capacity, institutional integration, and robust conflict resolution mechanisms in a politically contested regional environment.
