Applications of Value Transfer Function in Three Nature-Based-Solution Pilots
| Project | Essen’s Transition (from Gray to Green) | Coastal Mangrove Restoration (Bangladesh) | Conserving Biodiversity (Nile Basin Transboundary Wetlands) |
|---|---|---|---|
| Type | Urban | Mangrove restoration | Wetland conservation |
| Description | Former site of Krupp cast-steel factory; transformed into a 230 ha green belt | Established 9,650 ha of mangrove plantation | To strengthen technical and institutional capabilities to sustainably manage the region to limit drought and flooding |
| Continent | Europe | Asia | Africa |
| Risk being addressed | Flooding | Flooding, coastal defense | Flooding, droughts |
| Area (ha) | 230 | 9,650 | 320 |
| Population density | 2,715 | 1,180 | 1,280 (across Nile basin) |
| GDP per capita | 50,070 | 2,688 | 1,100 (avg. Nile basin countries) |
| Type of nature-based solution | Park | Mangrove | Wetland |
| Co-benefits provided | Recreation, species habitat, air quality, climate regulation, carbon sequestration, flood risk, aesthetic appreciation | Recreation, habitat for species, climate regulation, flood risk | Recreation, habitat for species, air quality, climate regulation, flood risk |
| Previous land use | Urban | Restoration | Conservation |
| Annal value per hectare | 533,870 | 160,764 | 96,244 |
| Annual total value | 122.7 million | 1,512 million | 30.8 million |
Note: The GDP and values are in 2022 US$. The contingent valuation method is set at 0.2 to reflect the sample average.
