Local productive arrangements for biodiesel production in Brazil: Environmental assessment of small-holders integrated oleaginous crops management.

Sustainability assessments were carried out in small-holders? farms in four territories where productive arrangements have been organized for production of minor oleagi- nous crops under the Brazilian biodiesel program. The study aimed at checking local impacts of the biodiesel productive chains at the rural establishment scale, and pro- moting the environmental performance of the selected farms, henceforth proposed as sustainable management demonstration units. Assessments were carried out with the APOIA-NovoRural system, which integrates 62 objective and quantitative indicators re- lated to five sustainability dimensions: i) Landscape Ecology, ii) Environmental Quality (Atmosphere, Water and Soil), iii) Socio-cultural Values, iv) Economic Values and v) Management and Administration. The main results point out that, in general, the eco- logical dimensions of sustainability, that is, the Landscape Ecology and Atmosphere, Water, and Soil quality indicators, show adequate field conditions, seemingly not yet negatively affected by increases in chemical inputs and natural resources use predicted as important potential impacts of the agro-energy sector. The Economic Values indica- tors have been favorably influenced in the studied farms, due to a steadier demand and improved prices for the oleaginous crops. On the other hand, valuable positive conse- quences expected for favoring farmers? market insertion, such as improved Socio-cultural Values and Management & Administration indicators, are still opportunities to be ma-terialized. The Environmental Management Reports issued to the farmers, based on the presented sustainability assessment procedures, offer valuable documentation and com-munication means for consolidating the organizational influence of the local productive arrangements studied. These productive arrangements were shown to be determinant for the selection of crop associations and diversification, as well as for the provision of technical assistance and the stabilization of demand - conditions that promote value aggregation and income improvements, favoring small-holders? insertion in the market. More importantly, these locally organized productive arrangements have been shown to strongly influence the valorization of natural resources and environmental assets, which are fundamental if sustainable rural development is to take place under the emerging agro-energy scenario.

Avaliação da efetividade do programa cisterna a partir da abordagem dos meios de vida.

Resumo: Este estudo objetivou analisar a efetividade do Programa Cisternas utilizando abordagens teóricas orientadas aos atores, a partir do desenvolvimento de novas práticas sociais implementadas pelos agricultores beneficiários do Programa para a convivência com o Semiárido brasileiro. Elaborou-se um estudo de caso selecionando a Comunidade Sítios Areias, localizada no município de Sobral (CE). A coleta de dados foi realizada com a aplicação de questionários às famílias beneficiadas pelo Programa. O marco teórico utilizado foi a teoria da Abordagem dos Meios de Vida para caracterizar a efetividade do programa e compreender o processo de mudança social. Constatou-se que o Programa apesar de utilizar os preceitos do paradigma de desenvolvimento sustentável para a sua implantação, não possibilitou a efetividade do programa em promover modificações das práticas sociais, não revertendo a estratégia de migração das famílias, ocasionada pelo processo de desativação dos beneficiários com a agricultura. A implementação do programa não conseguiu combater a pobreza rural, mesmo proporcionando o acesso à água as famílias. Concluiu-se que a forma de intervenção exigia uma nova dinâmica para o Semiárido, bem mais complexa do que simplesmente a construção de tecnologias sociais de captação de água. Recomenda-se políticas integradas e que contribuam para a melhoria dos meios de vida das famílias, mas que também ensejem seu protagonismo e o fortalecimento de sua autonomia frente às adversidades climáticas frequentes da região. [Evaluation of the effectiveness of the Cisterns Programe according to the Sustainable Livelihood Approach]. Abstract: This study was carried out in order to analyze the effectiveness of the Cisterns Program according to the new social practices implemented by the family farmers in order to survive and live in the adverse environment of the Brazilian semiarid. The empirical space chosen was the Municipality of Sobral (CE) and the case study was the Community Areia Branca. Data was collected on all the families benefited from the Cisterns Program. The analytical theoretical framework used was the Sustainable Livelihood Approach to characterize the effectiveness of the program and the process of social change. It was found that despite using the concepts of sustainable development paradigm in the implementation of Cisterns Program, the program was not effective in promoting social changes or to reserve the migration practice as well, which is a family strategy due to deactivation of agricultural activities. The implementation of the program failed to combat rural poverty other than providing access to water. The form of intervention in the semiarid requires a new dynamic approach, which is far more complex than simply building social technologies for water storage. In order to fight poverty in the region, it is necessary to implement integrated policies able to improve life style and bring about changes in order to empower and give autonomy to the families helping them to face the adverse climatic conditions typical of the region.

New perspectives on the history of brazilian agriculture.

One of the objectives of this book has been to highlight the importance of the history of agriculture in today's food production and consumption patterns, recovering parts of this history which are not easily found or which have been forgotten or neglected, but which have had a large impact on what we are today.
