TRUJILLO-UBALDO, Elizabeth et al. Cultivation shifts in forest plantations of Eucalyptus grandis Hill ex Maiden, in Uruapan, Tabasco. Rev. mex. de cienc. forestales [online]. 2018, vol.9, n.48, pp.27-46. ISSN 2007-1132.  http://dx.doi.org/10.29298/rmcf.v8i48.130.

Commercial timber plantations in Mexico have become an opportunity for increasing the production and productivity of the subsector, as well as for reducing the pressure on the natural forest areas and increasing the income of rural families. The objective of this research was to analyze the relationship and behavior between three different types of shifts: 1) Technical: Maximum Average Production (MAP) and Maximum Total Production (MTP); 2) Economic: Hotelling and Faustmann; and 3) economic-environmental: Hartman- in plantations of Eucalyptus grandis in the municipality of Balancán, Tabasco, Mexico, and to provide elements that may contribute to decision-making in the forestry companies. Data from three inventories provided by the company Productora de Plantaciones del Sureste were used. The type of average interest rates of the certificates of the Treasury of the Federation (CETES) (8 %), an average price of $107.00 tCO2e-1 (tab average used by the European Climate Exchange Carbon from 2010 to 2014), a cost of establishment of the planting of $38 000 ha-1, a price of roundwood of $650.00 m-3, and a cost of $2 000.00 ha-1 yr-1 were considered. The estimated shifts were the following: MAP (10.24 years), Faustmann (10.82 years), Hotelling (11.32 years), Hartman (11.64 years) and MTP (97.2 years). We conclude that the number of years increases as economic-environmental aspects are incorporated in the estimation of shifts.
