BLANCO, D et al. Integral procedure to contribute to the transition from agricultural to sustainable agroenergetic farms in Cuba. Pastos y Forrajes [online]. 2014, vol.37, n.3, pp. 284-290. ISSN 0864-0394.

Great efforts are made in Cuba to achieve a sustainable development that guarantees food security and energetic self-sufficiency, compatible with environmental protection. This purpose receives the contribution of the international project BIOMAS-CUBA, which has among its main objectives the promotion and implementation of sustainable agroenergetic farms, and within whose framework this study was conducted. An integral procedure was developed to contribute to the transition from agricultural to sustainable agroenergetic farms, which was structured into three stages: 1) initial diagnosis, 2) model of intervention, and 3) model implementation and evaluation of the change. For its validation, the procedure was implemented in two previously diagnosed farms, which had the most unfavorable energy balances among all the ones related to the Project. In both farms the richness of species (45 %), the productive diversity (25 %), agriculture-livestock production integration, productive volumes (45 %), capacity of the systems to contribute to the food security of people in the municipality (78 % of protein and 64 % of energy), as well as the energy balance (137 %) and the economic results (37 %), increased. In addition, the energy cost of the protein (an average of 141 %) decreased, with regards to the basis year
