In this sense Peiron (2000) cited by Palomino, (2010) concerns are also evident damage to health arising from residues of chemicals in fresh food, as well as the workers themselves responsible for implementing them, reducing the quality of the products. In this sense the need to convert pollutants, and conventional production systems in healthy production systems agro, which pollute less, which are economic and which are extendable to all farmers is compulsory. The Experimental Center of research and agricultural practices of the Institute University of technology Dr. Delfin Mendoza, (C.E.I.P.A) works on Guara Island, State of Monagas, Venezuela. Currently has nine (9), production projects including; six (6), they are livestock production and three (3) production plant, here are taught agricultural practices to the students of the careers of agricultural technology through the activities that are performed on each unit of production (CEIPA, 2010). Work schedules and manuals operational units of production in the CEIPA, are elaborated on the basis of knowledge of conventional agriculture and the technological packages that are used many times, are those developed by the manufacturers of the products laboratories, to increase your sales (Figure 1) these systems are difficult to eliminate due to ignorance of other alternatives for production that are scientifically proven (CEIPA2010). Fig.1 recurrent use of herbicides in established crops thereon Palomino (2010), citing Altieri, (2001) points out that the basic challenge of sustainable agriculture make better use of internal resources can be easily reached, and minimizing the use of external inputs and preferably generating internal resources more efficiently, through diversification strategies that increase the synergies between the key components of the agroecosystem. But how to make better use of internal resources, and what are the strategies that increase the synergies?, possibly the authors note the answers in his works, but then what are not deployed in Venezuelan production centres and why no progress has been made in this regard; possibly the answer is very simple, because it is suspicious of the efficacy of the agro-ecological methods, which often do not apply according to the defined methodology.
In this sense the author supports the hypothesis, the documentary investigation of alternatives agroecological to put them into practice in the CEIPA and convert it in this way in a model institution representative of the agro-ecological production, which can be imitated by the centres of production, thus helping to increase health in the population, with the consumption of healthy foods whose production processes do not harm nature. One of the proposed agro-ecological methodologies is the creation of demonstration plots where the producer can appreciate good practices for the management and efficient use of soil and the correct use of natural resources and to become advocates of these practices in their communities.
