Introduction
Mountain ecosystems are among the most fragile and biodiverse ecosystems on Earth. They provide essential ecosystem services such as water regulation, biodiversity conservation, soil stabilization, climate regulation, and cultural heritage. These ecosystems support millions of people directly and indirectly through agriculture, forest products, and tourism.
However, in recent decades, development initiatives and tourism have exerted significant pressure on mountain environments. Construction of roads, dams, hydroelectric projects, large hotels, trekking infrastructure, and unplanned urbanization in mountain regions have led to soil erosion, deforestation, biodiversity loss, water pollution, and cultural disruption. If left unchecked, these impacts can lead to the degradation of the ecosystem services that mountains provide, threatening both ecological balance and human livelihoods.
Restoration of mountain ecosystems requires scientific, socio-economic, and policy interventions that reconcile development needs with ecological sustainability. This essay explores the negative impacts of development and tourism, strategies for ecological restoration, successful case studies, challenges, and future prospects.
