Abstract: Abstract Even though ecosystem services have a significant contribution to human well-being, their value is not always recognized. Despite difficulties, the application of economic valuation methodologies to ecosystem services has grown significantly in the literature, in order to contemplate ecosystem services’ values in the decision-making processes at different levels. Soil erosion and the associated loss of nutrients has been a major concern worldwide and is expected to increase. The present study proposes the biophysical and monetary quantification of avoided soil erosion, in an area ranging from Serra de Arga to the Âncora river mouth, in Northern Portugal. The biophysical and monetary values were estimated using the Universal Soil Loss Equation and an indirect market valuation method—the avoided costs of erosion. The results indicate that 1,075,236.8 tons of soil erosion is avoided each year, which, according to the model used, has a value of 5,247,155.70 €/year or, on average, of 1144.00 €/ha/year. Although these values may represent an underestimate of the real value, this paper hopes to contribute to the recognition of the value of ecosystem services to human well-being, in order to promote a more sustainable use of natural resources, the preservation of ecosystems and biodiversity, and a sustainable economy.
