Economic valuation of land-use systems by liquid present value in José Crespo Castillo District, Perú
The objective of the study was to estimate the economic value of ten different systems of land use including monoculture of cocaine (Erytroxylon coca Lam), secondary forest 12 yr old, and eight agroforestry systems (AFS): SPS Echinochloa polystachya HBK, traditional and improved AFS cocoa (Theobroma cacao L.), AFS citrus (Citrus sinensis L.) 15 and 30 yr old, SPS Paspalum conjugatum Berg, AFS pupunha (Bactris gasipaes Kunth), and AFS coffee (Coffea arabica L.). The methodology used was interactive interviews to evaluate the farms’ infrastructure and equity situation and techno-economic aspects of the land-use systems. The economic indicators liquid present value, rate of internal return and ratio of income/costs of the systems were found to be positive, but their stability when subjected to changes of 10% in either prices or costs were highly variable. These alterations were small when compared with the assumed opportunity cost of 14%, thus indicating economic stability, in the cases of AFS citrus 30 yr old, AFS pupunha, AFS coffee, traditional and improved AFS cacoa, secondary forest and SSP E. polystachya, but not so for the cocaine, AFS citrus 15 yr old, and SSP P. conjugatum systems, that showed instability with negative economic effect.
