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

The document introduces a mathematical model for quantifying the physical and economic impacts of road disruptions, such as flooding and landslides, and assessing the value of nature-based solutions in mitigating these risks. The model incorporates climate forecasts and spatially explicit assessments of ecosystem services to provide a comprehensive cost-benefit analysis of resilience investments. It has been piloted in two Indonesian locations and used to train technical staff at the Ministry of National Development Planning (BAPPENAS).

• Nature-based solutions enhance road resilience by lowering the direct costs of infrastructure damage and reducing disruptions to road services.
• A comprehensive analysis of nature-based solutions for road resilience highlights the importance of accounting for indirect and induced environmental, social, and economic benefits beyond direct financial gains.
• The developed model utilizes climate forecasts and spatially explicit assessments of nearby ecosystem services to evaluate how floods and landslides affect road-related services.
