A precarização do trabalho: migrantes nordestinos no município de Leme-SP : caminhos, estradas e sonhos

This paper aims to examine the genesis of migration to the city of Leme-SP, as well as the influence of the social matrix northeastern expansion and redevelopment through the territorialization of the migrant population, particularly workers from the state of Ceará, migration from the 1970s. This process is evidenced by the territorial division of labor, through the economic, political and cultural insecurity through the work of cutting sugar cane, the territoriality of culture and northeastern faith in the city, and becomes another object before the materiality in which occurs. In this aspect, through dialogue between the sciences and arts, it was possible to show the historical importance of the phenomenon of migration in the country, in different scales and relationship that encompasses everything and everyone

Chronic Diseases: Chronic Diseases and Development 2 Health, agricultural, and economic effects of adoption of healthy diet recommendations

Transition to diets that are high in saturated fat and sugar has caused a global public health concern as the pattern of food consumption is a mayor modifiable risk factor for chronic non-communicable diseases Although agri food systems are intimately associated with this transition, agriculture and health sectors are largely disconnected in their priorities policy, and analysis with neither side considering the complex inter relation between agri trade patterns of food consumption health, and development We show the importance of connection of these perspectives through estimation of the effect of adopting a healthy diet on population health, agricultural production trade the economy and livelihoods, with a computable general equilibrium approach on the basis of case studies from the UK and Brazil we suggest that benefits of a healthy diet policy will vary substantially between different populations, not only because of population dietary intake but also because of agricultural production trade and other economic factors

Microbial populations and the activity of the soil under agricultural and agricultural-pastoral systems

The effects of agricultural-pastoral and tillage practices on soil microbial populations and activities have not been systematically investigated. The effect of no-tillage (NT), no-tillage agricultural-pastoral integrated systems (NT-I) and conventional tillage (CT) at soil depths of 0-10, 10-20 and 20-30 cm on the microbial populations (bacteria and fungi), biomass-C, potential nitrification, urease and protease activities, total organic matter and total N contents were investigated. The crops used were soybean (in NT, NT-I and CT systems), corn (in NT and NT-I systems) and Tanner grass (Brachiaria sp.) (in NT-I system); a forest system was used as a control. Urease and protease activities, biomass-C and the content of organic matter and total N were higher (p < 0.05) in the forest soil than the other soils. Potential nitrification was significantly higher in the NT-I system in comparison with the other systems. Bacteria numbers were similar in all systems. Fungi counts were similar in the CT and forest, but both were higher than in NT. All of these variables were dependent on the organic matter content and decreased (p < 0.05) from the upper soil layer to the deeper soil layers. These results indicate that the no-tillage agricultural-pasture-integrated systems may be useful for soil conservation.

Evaluation of tractive performance of four agricultural tractors in laterally inclined terrain

O presente trabalho teve como objetivo avaliar o desempenho operacional de quatro tratores agrícolas com tração dianteira auxiliar, em função de seis inclinações laterais, em uma pista lateral de ensaios, pertencente à Faculdade de Ciências Agronômicas da Universidade Estadual Paulista, Câmpus de Botucatu. As inclinações laterais foram 0; 5; 10; 15; 20 e 25 graus. em todas estas situações, os tratores operaram com carga predeterminada de tração imposta ao trator tracionado de 40 kN na inclinação de 0 grau. Portanto, foi utilizado um delineamento em blocos casualizados (DBC), sendo seis inclinações e quatro tratores, e com três repetições para cada tratamento. As variáveis analisadas foram patinhagem, força de tração, consumo horário de combustível e velocidade de deslocamento. Concluiu-se que a configuração dos rodados pneumáticos influenciaram no desempenho operacional dos tratores, conforme aumentaram as inclinações laterais do terreno.

Hunting spiders of woodland fragments and agricultural habitats in the Atlantic rain forest region of Brazil

The hunting spider communities of the Dionycha clade were studied 1986 through 1988 in fragmented woodlands and secondary agricultural habitats of the Botucatu area in São Paulo state, Brazil. The original vegetation of mainly tropical Atlantic rain forest (Mata Atlantica) was cleared already 70 years ago. In a total sample of over 1000 adult spiders, 247 species belonging to 12 families Mere determined. A decreasing frequency and diversity of spiders rc as found if forest remnants were compared with sugar cane fields and cattle pasture. The specific composition of the spider fauna as surveyed in different habitats is discussed under ecological aspects and in relation to the history of land use.
