Avaliação energética econômica da cultura do milho em assentamento rural, Iperó-SP

This paper, having as a hypothesis that greater energetic inputs don't keep ratio with economical outputs, has tried to study the economical and energetic flows in the maize cultivation to several production systems used in Ipanema Settling Area I, having as analysis instrument the indexes of Cultural, Energetic, Economical efficiency, which were added to the methodological proposal of Cultural Economical and Energetic Economical Efficiency indexes, built for probability settings. Four different systems have been identified: "A", "B", "C" and "D". The energetic expenditure were, respectively, 4,836.19 MJ x ha-1, 4,4647.17 MJ x ha-1, 4,639.49 MJ x ha-1 and 4,450.47 MJ x ha-1. In "A", where the use of machines is more intensive, the participation of biological source energy was 23.26%, whereas the ones of fossil origin are 76.74%. The "D" system has the greatest Cultural Efficiency, with average index of 16.26, whereas "A" showed the lowest Cultural Efficiency indexes, with average values of 14.83. For the analysis of the Energetic Efficiency, that indicates the dependence of energy from non renewable sources, the highest index was the "D" system with an average index of 53.84. The Economical Efficiency Indexes, which ranged from 1.84 to 1.96, show that all systems are efficient. The "D" system, with index equal to 8.84, showed the highest index of Economical Cultural efficiency. The Economical Energetic analysis for "A", "B", "C" and "D" systems, has resulted, respectively, in the following indexes: 21.14 ; 23.86 ; 22.87 and 29.26. Through the outcome analysis, it was concluded that the more intensive use of energy from nonrenewable sources ("A" system) didn't necessarily mean a higher efficiency when compared to "D" (labor intensive), what comes to prove the paper's initial hypothesis.

Produçao e comercializaçao em assentamentos rurais : Estudo do caso do assentamento Sao Domingos dos Olhos D'Agua (Morrinhos, Goiás - Brasil)

The paper aims to diagnose obstacles to the commercialization of agricultural production of the settlement of São Domingos dos Olhos D'Água, municipality of Morrinhos, Goiás state. The research is characterized as exploratory, with qualitative approach and field research. The results show that the difficulties in the commercialization of production, especially those produced with the based on agribusiness and intermediaries, can be overcome with the expansion of public programs to support family farms. It follows that family farming can be a viable alternative to combat the expropriation of the wealth produced by resettled farmers, especially with the establishment of commercializationmechanisms that connect them directly with the final consumer, such as the Food Acquisition Program (Programa de Aquisição de Alimentos).

As iniciativas e experiências em agroecologia como estratégia de desenvolvimento local em um assentamento de reforma agrária

This paper searches to understand which disputes and conflicts are around the consolidation of agroecology as one of the alternatives and initiatives of local development in a land reform settlement. Thus, this paper, which consists of one of the results presented in the author´s dissertation, aims to identify the disputes and conflicts that occur among local initiatives related to agroecology. Santa Rosa settlement is located in one of the densest areas in relation to rural settlements in Rio Grande do Sul (RS) State. The research sources used to collect data and references to this paper were obtained in: researched bibliography in the writing of the author's dissertation; academic articles; and perceptions from the author's experiences in some land reform settlements. In this research it was considered that initiatives and actions in agroecology in the studied settlement can be strategic to make the social relations potential to the occurrence of experiences in local development different from those that occur alongside agribusiness.
