SALMON, Yamilka; FUNES-MONZOTE, F.R  e  MARTIN, Olga M. Evaluation of the biodiversity components in the agroecological farm "Las Palmitas", Las Tunas municipality. Pastos y Forrajes [online]. 2012, vol.35, n.3, pp. 321-332. ISSN 0864-0394.

The objective of the work was to evaluate the components of functional biodiversity and their contribution to the productivity and efficiency of production in the farm "Las Palmitas" (Las Tunas province, Cuba). It has an area of 15,44 ha and it is dedicated to diversified crop, fruit and animal production. An agroecological characterization was made and the functionality of biodiversity was evaluated, from the design of a model of analysis as research guide which included the components: tree diversity, production diversity and species richness. Through the diagnosis the number of individuals of each agricultural and animal species was quantified, and they were characterized according to their functionality within the agroproductive system. The primary information sources were direct observation, informal interviews and application of a semi-structured survey, which included the variables of interest for the diagnosis. The Shannon (2,8) and Margalef (5,70) diversity indexes were calculated, which allowed visualizing the contribution of diversity to the increase of productivity. The diversity indicators of the agroecosystem reached optimum values for diversified systems, which contributed to food self-sufficiency, efficiency and productivity. The results indicate an economic and social relevance, conferring sustainability and resilience to the evaluated agroecological system, for which it constitutes a model for its dissemination under local or similar conditions as the ones in this study.
