Évaluation des actifs durables (SAVi) des infrastructures basées sur la nature dans le cadre d’un projet agroforestier à Welkenraedt (Belgique)

The report assesses a simulated agroforestry project in Welkenraedt, Belgium, covering approximately 100,000 m2 of hedges and trees. Using the SAVi tool and C3S climate data, the analysis demonstrates that the project is financially viable when environmental and social externalities are included. Key findings include estimated net benefits of 3.9 million euros over 20 years against an investment of 607,629 euros. The study highlights how agroforestry mitigates climate risks, such as reducing heat stress for livestock and preventing soil erosion and nutrient runoff, with benefits expected to increase under RCP 4.5 and RCP 8.5 climate scenarios.

• The agroforestry project is estimated to generate net benefits of 3,900,000 euros over a 20-year period, based on an initial investment of 607,629 euros.
• The project's financial viability increases significantly when externalities are included; the sustainable internal rate of return (TRI-D) is 27.85% and the sustainable net present value (VAN-D) is 1,430,000 euros.
• Climate change is expected to increase the economic appeal of agroforestry, as it mitigates negative effects such as flood damage, water pollution, and livestock heat stress.
• The project is expected to increase agricultural yields through a windbreak effect, with estimated additional revenues between 942,747 euros (10% effect) and 1,826,572 euros (19.38% effect).
• Spatial analysis using the InVEST model indicates that the project would lead to a 0.5% increase in carbon sequestration and a 1.896% improvement in habitat quality compared to a business-as-usual scenario.
• The project is estimated to reduce nitrogen exports by 377 kg and phosphorus exports by 102 kg in the surrounding watershed.
• The integration of C3S data allows for the simulation of impacts under RCP 4.5 and RCP 8.5 scenarios, showing that increased precipitation and runoff will likely increase the value of agroforestry's water treatment and flood prevention services.
