Consequencias da modernizacao da agricultura: o uso indiscriminado de praguicidas no municipio de Rio Claro (SP)

The modernization process has been introduced in the agricultural sector without any technical control. This process has provoked loss of food quality, serious damage to the worker's health and environmental degradation. The lack of technical assistance is total and farmers are not interested in the hazards involved. -after English summary

Difusão do trabalho agrícola formal no Brasil e sua dinâmica multiescalar

This paper aims to analyze the geographical dynamics of work from the spread of formal employment in the agricultural sector in Northeast Brazil. In recent years the region has had highlighted a growing movement to produce fruit for export, resulting in the promotion of important sociospatial transformations arising from the formation of a capitalist labor market. Data about the increase in the number of formal jobs show the impact of fruit growing agribusiness in the establishment of a new social and territorial division of labor. However, our study draws attention to the existence of a framework dominated for the vulnerability of the labor market by the persistence of seasonality and precarious working conditions.

Greenhouse gas mitigation potential from green harvested sugarcane scenarios in São Paulo State, Brazil

Brazil is a major sugarcane producer and São Paulo State cultivates 5.5 million hectares, close to 50% of Brazil's sugarcane area. The rapid increase in production has brought into question the sustainability of biofuels, especially considering the greenhouse gas (GHG) emissions associated to the agricultural sector. Despite the significant progress towards the green harvest practices, 1.67 million hectares were still burned in São Paulo State during the 2011 harvest season. Here an emissions inventory for the life cycle of sugarcane agricultural production is estimated using IPCC methodologies, according to the agriculture survey data and remote sensing database. Our hypothesis is that 1.67 million hectares shall be converted from burned to green harvest scenarios up to years 2021 (rate 1), 2014 (rate 2) or 2029 (rate 3). Those conversions would represent a significant GHG mitigation, ranging from 50.5 to 70.9 megatons of carbon dioxide equivalent (Mt CO2eq) up to 2050, depending on the conversion rate and the green harvest systems adopted: conventional (scenario S1) or conservationist management (scenario S2). We show that a green harvest scenario where crop rotation and reduced soil tillage are practiced has a higher mitigation potential (70.9 Mt CO2eq), which is already practiced in some of the sugarcane areas. Here we support the decision to not just stop burning prior to harvest, but also to consider other better practices in sugarcane areas to have a more sustainable sugarcane based ethanol production in the most dense cultivated sugarcane region in Brazil. © 2013 Elsevier Ltd.
