Valoración económica de las plantaciones de teca (tectona grandis) y balsa (ochroma pyramidale) en tres cantones del Litoral Ecuatoriano

The research was carried out in three localities are in three cantons of Ecuadorian Coast: the first was located in Quevedo, Los Rios province, located between the coordinates 01 º 03 '18''South and 79 º 25' 24''West. The second location in Balzar, Guayas Province, whose location is 01 ° 21 '39''South and 79' 04 '00''West. The third area corresponds to Quinindé, province of Esmeraldas, which is located between coordinates 00 º 18 '19''South and 79 º 27' 45''. We analyzed the economic value of environmental goods and services proceeds of teak (Tectona grandis) and raft (Ochroma pyramidale.). Descriptive statistics were applied (X, SD, Max, Min, ES). To select the species, cantons and sites are considered the homogeneity of the species, according to the study area, topography, plant, age, climate, management practices and land use type, vegetation type, agronomic management, history of area, among others. Plantations took 10 years of age in the case of teak and 3 years of age in the case of the raft. Destructive method was applied to measure the amount of carbon in plantations. We performed a randomized complete (DCA) in a factorial arrangement 3 (Cantonese) x 2 (species) x 4 (sitios. used the Tuckey test (P = 0.05). The variables were active organic carbon content biomass and organic carbon content in the soil active. The economic assessment was performed using the methodology of total economic value (TEV) considering direct use values, determining investment, costs and revenues in the culture of teak and balsa. Shadow price is used for both the value of the property (timber) and services (carbon), the latter under the stage "reducing emissions." The projection of the wood was made by IMA and the average DAP to evaluate land use applied the opportunity cost method, was established economic and financial indicators IRR, NPV and BC. The carbon fraction varied between 47.7 and 56.60% of the components of the tree, presenting the highest concentration of carbon shaft 59.37% 50.71% Teak and rafting, on the other hand, teak showed greater ability to store carbon in biomass 52.51% whereas, the raft has a greater capacity to store carbon in soil (76,735%). Total carbon accumulation in the system showed significant differences at the level of cantons and species, teak and adds to the raft 203.39 145.81 Tm ha-1. The income generated by the sale of timber is higher than the income generated by the sale of carbon certificates in a 20 and 5 years in teak and balsa, respectively. The valuation of the assets of teak and balsa show that these crops are profitable, feasible and viable as the market rate exceeds 12%, likewise, to consider the criterion of non-VET to fell the trees which was 4.48% TMA , the IRR and NPV showed that investment is feasible as the alternative to preserve the teak plantations vs. land use change is feasible.
