PURROY-VASQUEZ, Rubén et al. Energetic-economic flow as a tool to typify agroecosystems in the center of the state of Veracruz, Mexico. Ecosistemas y recur. agropecuarios [online]. 2016, vol.3, n.7, pp.91-101. ISSN 2007-901X.

The high energetic costs and the low productivity of some agroecosystems (AES) at a global level pose the challenge of suggesting strategies for its redesign. To this end, it is necessary to know the relations between the operative, productive, and financial structures of the agricultural components (AC) that comprise the AES. The objective of this study was to evaluate the energetic-economic flow as a tool to typify the AES based on their productive, economic, and energetic efficiencies and their agricultural diversity index. The data of a survey answered by agricultural producers of the municipality of Paso de Ovejas, Veracruz, Mexico had multivariate analysis techniques applied in order to differentiate the types of AES: hierarchical agglomerative grouping and k-media, ANVAR and means tests (Tukey; p<0.05). Three types of AES were identified: Entrepreneurial (E), Transitional Diversified (TD), and Traditional (T), with frequencies of 37, 17, and 46 %, respectively. Type E had the most efficient energetic-economic balance and the lowest diversity, predominantly due to the production of sugar cane. Type TD showed a greater total income and agricultural diversity by predominantly managing a combination of corn (C) and cattle farming (CF). Type T was found in the low hills area, with a low energetic-economic balance as a result of the low productivity of its AC (C and CF). In conclusion, the energetic-economic efficiency of the AES depends on the combination of the agricultural components that comprise them, product design of the producers, objectives and the agro-ecologica I characteristics of where they are found.
