This report presents the results of a post-intervention impact assessment and cost-benefit analysis carried out as part of the Roadside Spring Protection in the Himalayas (RoSPro) project in Nepal. The study focuses on four spring sites in the Koshi region, where integrated measures were implemented to protect mountain springs alongside rural roads—ensuring water availability, reducing road maintenance, and improving livelihoods.
The findings highlight major improvements: household water access rose from 53–65% to 92–97%, agricultural production increased by 43%, and daily water-fetching time dropped by up to 78 minutes. These changes not only improved quality of life but also enabled income growth—up to 25% for over a third of households—while strengthening resilience in local communities.
Financially, the interventions proved highly viable. All sites demonstrated positive Net Present Values, Benefit-Cost Ratios between 4 and 8, and Internal Rates of Return from 44% to 122%, showing that nature-based, integrated water and road management delivers strong economic and social returns.
