O Circuito espacial de produção do biodiesel: configuração no território brasileiro e uso do território Norte-Rio-Grandense

This research aims to understand the use of the territory from the Rio Grande do Norte to the circuit spatial of production from the Biodiesel understanding it as part of the national context. The introduction of biodiesel into the Brazilian energy matrix begins to take shape in the year 2005 with the implementation of the National Program for Production and Use of Biodiesel (NPPB). This is anchored on three pillars: social inclusion (through family agriculture), environmental sustainability and economic viability. The NPPB consists of a set of standards, which turned into shares and distributed by almost all the national territory. Our reflection assumes that the places accommodating different forms of productive activities and, thus, the performance of the circuit space of biodiesel production depends on several factors, including the configuration of the territory they receive this new nexus economic. Understanding that the places by their technical content determine the realization of productive activities, it was found that the inclusion of this circuit space production in Rio Grande do Norte, reveals the reality expressed in the national territory, where some places are endowed with a privileged technical content and other extremely poor infrastructure. As our research could confirm the circuit space of biodiesel production that is expressed in the way plants are distributed within the country (mostly in South-Central), in more significant participation of small farmers in the South in the supply of raw material for the production of biodiesel and the main raw material used for the production of agrofuels (soybeans, whose production sector is highly consolidated and technified). Already the project materialization of NPPB regarding the settlements and communities of the Rio Grande do Norte State, we observed that the "event" or advent of realization encountered a technical means lacking in infrastructure that need to be molded to the needs of production, or is to cultivate castor beans or sunflower would be needed inputs and implements that farmers don´t have. Given the above, the research concludes that, as proposed previously, the use of the territory of Rio Grande do Norte to this circuit has summarized the performance of experiments, either with regard to the participation of family farmers as suppliers of raw materials, including the development of related research in the stage of production fuel oil by Petrobras. This finding came from research done from the concept of "spatial circuits of production," which allowed the verification of the circuit that steps outlined in Potiguar territory. Regarding the inclusion of family farmers in the productive circuit in RN, research reveals that, in the manner as has been done, it is doomed to failure. Furthermore, we dare say that this persistence in trying to put these family farmers, the way is being made, and the resulting successive failures, indicating that social inclusion advocated by NPPB not take place, and that this production circuit relies on the same logic circuit concentrated and exclusive space for ethanol production

Produtividade e desenvolvimento de cultivares de repolho em função de doses de boro

A cultura do repolho é cultivada em áreas pequenas e necessita de muita mão de obra, sendo na maior parte conduzida pela agricultura familiar. Avaliou-se o efeito de doses de boro em diferentes cultivares de repolho na região oeste de Mato Grosso do Sul. O experimento foi conduzido na Universidade Estadual de Mato Grosso do Sul (UEMS), Unidade Universitária de Aquidauana. O delineamento experimental utilizado foi de blocos casualizados no esquema fatorial 2 x 5, sendo duas cultivares e cinco doses de boro, com quatro repetições. Foram avaliadas as características: teores de boro foliar, área da planta, altura de planta, número de folhas externas, massa fresca de folhas externas, massa seca de folhas externas, altura da cabeça, diâmetro da cabeça, número de folhas internas, massa fresca de folhas internas, massa seca de folhas externas, classificação do peso da cabeça, compacidade e produção por hectare. A cultivar 60 Dias apresentou maiores valores nos componentes de produção e conseqüentemente maior produtividade. A aplicação de boro influencia linearmente nos teor de boro foliar, diâmetro de cabeça e número de folha interna. As doses de boro interferem na produtividade de repolho, sendo que na cultivar 60 Dias a dose máxima é de 7,2 kg ha-1 e para cultivar Chato de Quintal a dose mínima deve ser de 1,06 kg ha-1.

In vitro Anthelmintic effect of Melia azedarach L. and Triclinia claussenii C. against sheep gastrointestinal nematodes

The control of parasitic diseases in small ruminants is mainly done with the use of synthetic anthelmintics. However, incorrect and indiscriminate use of these products has caused the emergence of parasite resistance. Plants with anthelmintic activity are used in folk veterinary medicine, but it is necessary to investigate and scientifically validate low-cost phytotherapeutic alternatives for future use to control gastrointestinal nematodes in small ruminants by family farmers. Thus, the aim of this study was to evaluate the in vitro anthelmintic effect of plant extracts from Melia azedarach and Trichilia claussenii by the egg hatch test (EHT) and larval development test (LDT) against sheep gastrointestinal nematodes. The hexane extract of M. azedarach fruits was extracted through cold percolation and the methanol extract of T. claussenii leaves was obtained by extraction at room temperature in solvents in order of increasing polarity. The efficacy results were analyzed using the Probit program of SAS. The M. azedarach extract showed a LC50 of 572.2 mu g/mL and LC99 of 1137.8 mu g/mL in the EHT, and LC50 of 0.7 mu g/mL and LC99 of 60.81 mu g/mL in the LDT. In turn, the T. claussenii extract presented a LC50 of 263.8 mu g/mL and LC99 of 522.5 mu g/mL in the EHTand LC50 of 1.11 mu g/mL and LC99 of 26.4 mu g/mL in the LDT. Comparing the extracts of the species from the Meliaceae family, T. claussenii showed greater anti-parasite potential in vitro than M. azedarach. However, studies on the isolated compounds, toxicity and administration forms to animals are also needed to validate low-cost alternative herbal remedies for use to control gastrointestinal nematodes by family farmers.

Aspectos Históricos e organizacionais da agricultura familiar no desenvolvimento da região Nova Alta Paulista

Nova Alta Paulista region, with strong aptitude for agribusiness, is one of the poorest in the state of São Paulo. However, the development of agribusiness productive chains in the region is very heterogeneous. The study aimed at analyzing how the historical background and organizational arrangements in family farming have contributed to regional development by promoting improvements in social welfare at Nova Alta Paulista region. To this end, we analyzed the case of the Associação Agrícola de Junqueirópolis - AAJ, an organization that has been successful in the search for alternative of agricultural production. Integrated to local and global market, this organization has ensured the maintenance of many farmers and generated positive externalities for the entire region. Thus, this case shows the organizational arrangement based on cooperation can be an alternative for family farmers achieve higher levels of welfare and development.

A emergência da agrindústria de processamento de frutas no Nordeste paraense, região metropolitana de Belém e no Marajó: uma análise do potencial da capacidade produtiva e inovativa sob a ótica de Arranjo e Sistema Produtivo Inovativo Local – ASPL

O Arranjo Produtivo Local (APL) de Processamento de Frutas do Nordeste paraense, Região Metropolitana de Belém e ilha do Marajó, na Amazônia Oriental Brasileira, se destina ao atendimento dos mercados local, regional e nacional. O APL oferta produtos a partir de frutas regionais e exóticas. A base rural agrícola apresenta capacidade produtiva crescente constituída por agricultores familiares. Esses agricultores têm, relativamente, reorientado suas produções para diversificação e complexificação, onde a fruticultura tem destaque nesse processo. O APL se diferencia tanto das estruturas informais (micro-escala) de processamento do fruto açaí (mercado local), quanto das indústrias de larga escala voltadas às exportações. O APL apresenta taxas de crescimento elevadas, porém, com potencial de rentabilidade limitado por condições estruturais. Por um lado, essas limitações refletem o baixo nível da capacidade de governança e de cooperação entre as empresas. De outro, são o resultado de uma baixa capacidade de interação do conjunto de empresas do APL com o ambiente institucional. Assim, há dificuldades para consolidar e elevar a capacidade produtiva e inovativa das empresas.
