Produtores familiares e estratégias ligadas à terra

A manutenção e/ou a ampliação da terra compõem o eixo central em torno do qual os produtores familiares organizam sua vida e seu trabalho. Este artigo analisa as estratégias desses produtores em relação à divisão de herança e à sucessão, e as formas que utilizam para aquisição de novas áreas. O levantamento das características das famílias e da propriedade foi realizado por meio de um questionário aplicado junto a 89 produtores familiares de três municípios da mesorregião de São José do Rio Preto (SP). Posteriormente foi entrevistado um terço dos produtores de cada município que havia respondido ao questionário. A análise das estratégias fundiárias mostrou uma grande diversidade na forma de partilhar a herança e de conduzir a sucessão, sendo que ambos os processos são apoiados, basicamente, em regras tradicionais, embora mantenham uma fachada de adequação às normas legais. Quanto às estratégias de aquisição de mais terras, observou-se que os produtores são capazes de organizar complexas formas de capitalização, centradas em maiores esforços no trabalho e na contenção de gastos, além da utilização de políticas públicas favoráveis e de práticas costumeiras. Os arranjos intra-familiares e as formas de cooperação ligadas ao parentesco mais amplo também se mostraram importantes para a ampliação da propriedade.

Fish Migration, Dams, and Loss of Ecosystem Services in the Mekong Basin

The past decade has seen increased international recognition of the importance of the services provided by natural ecosystems. It is unclear however whether such international awareness will lead to improved environmental management in many regions. We explore this issue by examining the specific case of fish migration and dams on the Mekong river. We determine that dams on the Mekong mainstem and major tributaries will have a major impact on the basin's fisheries and the people who depend upon them for food and income. We find no evidence that current moves towards dam construction will stop, and consider two scenarios for the future of the fisheries and other ecosystems of the basin. We conclude that major investment is required in innovative technology to reduce the loss of ecosystem services, and alternative livelihood strategies to cope with the losses that do occur.

Sprawling and Urban transportation system: Impacts in the city of Londrina, Parana, Brazil

After nearly 80 years since the construction of its core, represented today by the city's central area, Londrina, located in the state of Parana, has the appearance of a new city but its features and trends of planning policies depict the bad examples of Brazilian cities. With a booming urban growth, from north to south of the county, the urban interstices represented by big voids in the middle of the city created speculation and the concept of an ideal city slowly disappeared. With a metropolitan appearance and, at the same time, with small town aspects, Londrina stands out as an automobile-oriented city, a fact that has impacted the livelihood of the population, generating environmental impacts for all social classes. This paper discusses how the form of occupation in Londrina, characterized by the sprawl phenomenon and its relation to car preference as a mode of transportation has generated urban environmental impacts. It was concluded that the choice of using cars in Londrina, as well in other medium-sized Brazilian cities studied by the comparative method, has increased and has generated bottlenecks in traffic. As a consequence, there is a constant expropriation of properties for widening roads and at the same time, the presence of various densities and urban voids that form an uneven urban space and an obstacle to efficient urban planning. © 2012 WIT Press.

Análise econômica da criação de tambaqui em tanques-rede: estudo de caso em assentamento da reforma agrária

Aquaculture is a crucial source of income and livelihood for millions of people around the world. Most fish farms require technical knowledge expertise and qualified staff. This research was developed in Santa Felicidade Settlement Project Cocalzinho de Goias city - GO, where a substantial part of the settlers by INCRA are exploring subsistence farming activities. After meeting open to the 76 settler's families, those who joined the project received courses on intensive farming of tambaqui (Colossoma macropomum) in net cages. The production was an innovative technique, fully realized with the participatory labor of family members, without prejudice of the main activities. The economic analysis showed the return on invested capital in 7.5 years within the financial activity with 7.1% Internal Return Rate higher than the average interest rate market. The Net Cash Flow showed ability to fulfill financial obligations from the second year. The implementation of more productive cycles optimizes the workforce with increased operational efficiency. Diet alternatively produced with local ingredients can minimize the effects of critical variables of the project, since it does not affect productivity.

Comunicação através da arte e das novas tecnologias que renovam e complementam a renda familiar

Sustainability suggests a new social organization required for human survival. The aggravation of environmental problems arising by population growth, industrialization, disorderly and unconscious consumption of Human Being, induces us to think about how to stop these problems. Recycling presents itself as a means of stopping environmental destruction and as a way to increase the family income of the poorest society existing in our globalized world. This article suggests a research on recycling being carried out as a means of livelihood.

Trabalho e saúde: o cotidiano dos catadores de lixo reciclável

The present article is an investigation / action regarding the working conditions for pickers of recyclable waste in a medium-sized city in the state of São Paulo, mainly on the health / illness process, problems related to social security and conditions of autonomy and citizenship. We use the constructs of social psychology as theoretical. The recycling of urban garbage, as the literature indicates, is not being treated as just part of the solution to environmental problems, but also has been characterized as a source of income and livelihood for many people, with no other options in life. From the interviews were semistructured, and with the method of analysis the meaning core were identified issues related to the holding of by scrap collectors, prejudice existing in relation to the activity performed, poor housing conditions, the need to social recognition and the difficulty of recyclable garbage collectors in forming a group in which they can articulate and fight for their demands. With this study, we intended to indicate suggestions for improvements in these health professionals and encourage individual and collective reflections on the condition of meetings and also through the distribution of leaflets.
