Combinação ótima de atividades agrícolas para o projeto integrado de colonização de Altamira-Pará

Abstract

During 1970's, the policy of national integration in Brazil, tried to incorporate large marginal area and population to the country's development process. The construction of the “Transamazonica" road, connecting the North-East with the Amazonia region, was started. In the State of Parã were created three colonization projects, namely: PIC-Marabã, PIC-Altamira and PIC-Itaituba. Out of the three, the PIC-Altamira project is the only one that presents some vitality, but the majority of the farmers continue to plant annual food crops, producing small execedent, and their income is substantially low whem compared to those planting perennial crops. This study has the objetive of establishing, among the various available adequate alternatives a combination of activities that may increase the income level of the project's rural producers. The determination of the optimal combination of activities will be done by taking into consideration the actual activities, the introduction of new activities and tecnological innovations. The geographical area studied in the research is located along the "Transamazonica" road, strech of Altamira/Maraba. The sample consists of producers that receive extension service by EMATER-PA and were selected randomly. the basic information was obtained by interviewing the land owners. Three basic models were identified in the population studied. As a consequence, three typical farms were defined. Through linear programming, it was made the planning of the typical farms, finding the activities combinations. That maximize their annual incomes. It was found, that the incomes may be considerably increased with the realocation of the available resources, with the introduction of cotton "herbaceo" as a new activity, and also with the introduction of technological innovations in the rice crop.
