Limestone Mining in the Himalayas: Advancing Adaptive Governance for Ecological and Socioeconomic Resilience

Abstract

The Himalayan region, recognized as a global biodiversity hotspot, faces the dual challenge of promoting economic growth while ensuring ecological sustainability. Within this context, this research explores the impacts of limestone mining, a significant economic driver, on the environment and communities, specifically in Sirmaur. Our objectives were: Firstly, to analyze guidelines for the Impact Assessments of Non-Coal Mining projects and recommend sustainable strategies; and secondly, to discern the effects of limestone mining on crucial parameters such as hydrology, public health, biodiversity, and livelihoods. The findings highlight that while mining propels economic growth, certain practices, notably open-pit techniques, pose significant environmental risks. These risks highlight the importance of long-term commitments to land rehabilitation targeting the creation of self-sustaining ecosystems. Despite the critical nature of reclamation, its implementation remains inconsistent across the region. Waste from mining presents a potential for value addition, especially when repurposed for construction, wastewater treatment, etc.. Enhancing the quality of impact assessments is achievable through technological tools like remote sensing and geospatial analysis. Coupled with community-centric air and water quality monitoring, these methods can better inform mitigation strategies and policy decisions. To adopt the sustainable practices, a holistic approach is essential, incorporating environmental science, engineering, social dynamics, and policy-making. While participatory models engaging communities throughout the mining project lifecycle have shown promise, there is an urgent need to transition these models from mere consultation to genuine collaboration. As the Himalayas stand at the crossroads of development and conservation, this research emphasizes the importance of adaptive governance to protect both ecological and community well-being, especially in the face of climate change challenges. The findings provide essential insights and lessons that are globally applicable, emphasizing the potential of collaborative action to harness resources sustainably for future generations.
