Confronting Farmers’ Perceptions of Climatic Vulnerability with Observed Relationships between Yields and Climate Variability in Central Argentina

AbstractFarmers’ perceptions of climate variability is compared with the sensitivity of observed yields for wheat, maize, soybean, and sunflower crops to interannual and intra-annual climate variability in two districts (Junin and San Justo) in central Argentina from the 1970s. A recent transition occurred here between mixed crop and livestock farming to a more specialized system, dominated by transgenic soybean combined with glyphosate. According to the ethnographic fieldwork, farmers ranked drought first and flood second as the main adverse climate factors in both districts. Overall, the farmers’ representations fit rather well with the observed relationships between interannual variability of yields and rainfall, especially in Junin. The adverse impact of long-lasting dry spells, especially during the first half of the crop cycle, is usually combined with the more linear impact of large rainfall amounts (anomalously positive/negative rainfall amounts associated with anomalously positive/negative yields...

IMPACTOS DE LA DIÁSPORA CIENTÍFICA Y TÉCNICA EN EL SECTOR BIOTECNOLÓGICO ARGENTINO

In the capitalism economic history the search for the economic development was always associated with industrialization. However, with internationalization of the production and the great technological innovation, the industrialization did not solve the problem of underdevelopment. This thesis wanted to analyze the relation between industrialization and economic development and the limits of the regional public politics in this process, especially what happened in the region of Vale do Paraiba in Sao Paulo state after the Second World War. Analysing the series of historical quantitative information, limited in respect to development, it was possible to conclude that the politics of economic development in Vale do Paraiba succeeded in relation to the economic growth, but failed in the process of space distribution of the income, with your great concentration after these politics on 70’s, due to the reduction of the spillover on the other neighbouring areas. The politics of regional development must be reconsidered with actions that favours the endogenous politics in this economic world more and more global and with local social responsibilities.
