Forest Landscape Restoration Simulation to asses costs/benefits: case study Peruvian dry forest

Forest Landscape Restoration (FLR) aims at re-establishing the ecological functionality of degraded terrestrial ecosystems, as well as changing land-management practices to sustain local economic growth for the benefit of local livelihoods and for society in the long term. FLR projects embracing quality planting material, in terms of genetic diversity and site adaptation, provide better performances regarding growth and resilience. Consequently, they are expected to deliver a more efficient cost-benefit ratio. This study proposes a numerical model that simulates a one-hectare FLR project in order to explore the dynamics of the cost-benefit ratio over a period of 20 years. The model takes into quantifies the impact of the use of quality planting material on the health of the plantation and its consequent economic value. A case study of a Prosopis pallida plantation in the dry forest of the north of Peru shows no relevant additional costs, but significant additional benefits of the use of quality planting material. These results hold both for an intensive commercial plantation and a conservation project that entails almost zero maintenance.
