Ecosystems Protecting Infrastructure and Communities, Nepal (2012-2017)

•  How to quantify ecosystem services for erosion reduction? •  Economic costs and benefits of bio-engineered or “green

roads” vs.“grey”/conventionally constructed roads? •  How effective are various commonly used bio-engineering

plants in slope stabilization, considering climate change factors?

Pakistan 2005: 3,000+ earthquake-induced landslides

Page 10: Sudmeier may 2015  know 4 final

Results: remote sensing, field study

• 100 landslides profiled • 17 km 2 surface area • 84 on right bank • Similar geology and slope gradient (50-55°) • Private ownership vs. state regulated • Vegetation cover highly degraded on right bank • 56% grazing, followed by occurrence of roads Sudmeier-Rieux et al. (2011) Correlated by Peduzzi (2010)
