VALDES, N  y  MARQUEZ, M. Evaluación del índice de estabilidad a nivel de ecosistemas agrícolas. cultrop [online]. 2009, vol.30, n.2, pp. 00-00. ISSN 0258-5936.

This research work deals with some evaluative aspects of the stability index in agricultural ecosystems, with the aim of validating its application according to the climatic change, food and nutritional security, besides proving the general ecosystem contribution. The proposal includes and evaluates physical properties, elements of agricultural and forest diversity, as well as of energy performance. The proposed indexes were calculated after recording some measurements in 10 small producers´ farms from Pinar del Río. Results show the index built up constitutes a useful tool for providing agricultural ecosystems to mitigate greenhouse gases, food and nutritional security; also, these ecosystems are very far from achieving significant contributions to the proposed objectives.

Palabras clave : ecosystems; stability; food security; climatic change.
