Developing and Piloting a Model for Estimating the Direct and Indirect Benefits of Nature-Based Solutions for Road Resilience in Indonesia

This methodology report describes the development and piloting of an integrated cost-benefit analysis model designed to estimate the direct and indirect benefits of nature-based solutions (NbS) for enhancing road resilience against natural hazards in Indonesia.

• Traditional engineering methods often fail to adequately address natural hazards such as flooding, erosion, and landslides that threaten road infrastructure, particularly when roads are constructed by removing natural land. Integrating nature into road design and planning is proposed as a solution to enhance resilience.
• The developed model uses climate forecasts and spatially explicit assessments of ecosystem services near roads to quantify the physical and economic impacts of road disruptions. It aims to highlight that investments in NbS provide not only direct cost reductions regarding road damage and service disruptions but also indirect and induced social, economic, and environmental benefits.
• The model was piloted in two locations in Indonesia and has been utilized for training technical staff within the Ministry of National Development Planning (BAPPENAS).
