This Sustainable Asset Valuation (SAVi) examines how nature-based infrastructure (NBI) interventions like reforestation, slope stabilization, and hydrological restoration can strengthen mine closure plans in Marmato, Colombia. For every USD 1 invested in progressive closure with NBI, the region gains USD 1.44 in return while also reducing exposure to landslide risk, water contamination, and ecosystem degradation.
