Nature-based Solutions Examples in practice IUCN, the International Union for Conservation of Nature

Nature-based Solutions at Scale Development impacts Natural resource management Conservation outcomes actions ➢ Poverty reduction (SDG1) ➢ Green growth & jobs E.g. (SDG 8) E.g. Landscape - Catchment ➢ Food and water restoration rehabilitation security (SDG 2 and - Habitat protection 6) ➢ Climate change mitigation (SDG 13) ➢ Resilience and risk management (SDG1 Impact Pathway: ascending diversity/breadth of outcomes and 11)

Rangeland restoration

Benefits of rangeland restoration

Cost-benefit of restorin ing 100,000 hectares over 25 years Benefits Natural forage / Rangeland productivity 20.5 million Groundwater percolation 188.5 million Sediment control 9.1 million Carbon sequestration 6.9 million Total Present Economic Value 255 million Costs Community surveillance and biomass 7.3 million studies Benefits – Costs Total Net Present Value of restoration 217.7 million
