Short summary

Road development in Nepal promises to improve access to markets, education and healthcare, but not without hazardous consequences. Using GIS maps of monsoon-triggered landslides, we show that rural roads are responsible for doubling the number of landslides in one mountainous district. Engineers are seeking sustainable and affordable eco-solutions to help stabilize these roads in order to prevent further loss of life and property as Nepal approaches this next phase in its development.
