Summary: Faced with the growing economic and social importance factor manpower under plastic vegetable farms in the province of Almeria, arises implement and evaluate an automated control times based on the techniques of Study Times, in order to develop a system for managing manpower applicable to these sites. The proposed management system is structured in three phases: Phase data capture, the stage of processing and analyzing data, and finally the planning stage. For Stage processing and data analysis, it is proposed to implement the technique of Graphics Control and allowing ruled, in a systematic way, the records with abnormal values. Have been explored during three campaigns (2002 to 2005), records of working time for the tasks of the agricultural crops of peppers and tomatoes in a greenhouse of 115,000 m2 located on the Term Municipal Níjar (Almeria). As most important results have been obtained average yields and yields standard for the most important tasks of both crops. For the calculation of performance are giving, a method that allows you to select efficient operators with more experience. There have also been calculated for both crops, the weekly needs of manpower along the entire campaign. In parallel, we wanted to check the influence of the environmental conditions in the performance of operators. To that end, there are lines that relate regression with temperature and humidity performance. The correlation coefficients are low and negative value. Finally, we performed a series of proposals to reduce errors in data entry and allow standardization of working methods. We believe that the proposed management system is applicable to vegetable farms in the province of Almeria and that, among other uses, allows adequately plan and optimize manpower requirements.

Summary: The Region IX, Chile has suffered over the past 100 years in the profound process of transformation systems económicoproductivos and in the state of natural resources, introducing today's high levels of degradation and poverty of the rural community (mainly Mapuche community) . usually from official sources, tends to be associated Mapuche poverty and environmental degradation to technical deficiencies, holding that the solution lies in the modernization of its production systems and social. Thus, the investigation tries to answer the following questions: Do you is the "modernization" a sustainable solution in this context?, If not, what alternatives exist Â? Â And how assess their sustainability for indigenous context, "Do you agroecology presents the elements needed to serve as an alternative?. These questions are addressed by the inquiry into the economic, ecological and social challenges of the past, the present state of ecosystems and the Mapuche themselves, and the integration of these dialectics, territorial organizations themselves, to finally get the perspective of future Mapuche and the definition of a productive style of economic development itself. Based on this conclusion, are tested alternatives that are currently raised for agricultural development Mapuche (pr: uductivista, sustainability ecotecnocratica) evidenciándose mismatch between these and peasant and indigenous context. It also identified the main theoretical perspectives of agroecology and verified in this reality. Through this analysis could conclude that neither the modernization of farming systems or application programs derived sustainability ecotecnocratica show consistency with epistemológica styles differential development of the road egemónico, the same thing happening with proposals from the agroecology not take the break epistemológico and methodological model and the objectives pursued. However, it also outlines a new "agroecology criticizes" more adequacy of accompanying these processes.
