2. Where is sugarcane cropping expanding in the brazilian cerrado, and why? A case study
ABSTRACT Sugarcane growing area in Brazil sharply expanded between 2000 and 2010 due to the increasing world demand for sugar and ethanol. Since this expansion of sugarcane is said to occur in areas covered by degraded pastures, it is likely not threatening the environment or food production. In order to verify this assumption, we investigate at farm and fie

3. ECONOMIC AND FINANCIAL VIABILITY OF DIGESTER USE IN CATTLE CONFINEMENT FOR BEEF
ABSTRACT This research analyzes the economic and financial feasibility of implementing a biodigester for confinement of beef cattle on a farm located in the State of São Paulo, through the approach of discounted cash flow. The anaerobic digestion technology arouses interest, due to its advantages with the generation of electricity and the pollution reductio

4. Economic and socio-environmental performance assessment of beef cattle production systems: a data envelopment analysis (DEA) approach with weight restrictions
This study evaluated the performance of 21 beef cattle modal production systems that conduct only the raising phase. These production systems were developed in 21 municipalities in seven Brazilian states. We used two different DEA BCC models, corresponding to different points of view. Firstly we used an economic model that measured the ability of a productio

5. Determinação de resíduos de agrotóxicos em leite bovino empregando método QuEChERS modificado e GC-MS/MS
Considering the possibility that pesticides used in cattle raising produce residues in milk and cause harm to public health, this study developed a multiresidue method for determination of pesticide residues in bovine milk, using a modified QuEChERS method for sample preparation, and quantification by GC-MS/MS. The method proved to be efficient, resulting in

6. As Novas ruralidades e as recentes alternativas da agricultura familiar no município de Itapiranga (SC)
The new rurality is creating job opportunities and income in family farming in the municipality of Itapiranga/SC, which must be analyzed. Have been numerous initiatives in this direction, such as recreation sites, agro-ecological gardening, farming, forestry, fish and small agro-industries derived from cane sugar (molasses, brown sugar and "Schmier"), rural

7. Uso das terras e legislação ambiental: a microbacia do Ribeirão Sapé no município de Caldas Novas (GO) / Land use and environmental legislation: the micro-basin of the municipality of Ribeirão Sapé in Caldas Novas (GO)
From the 1930s Brazil created many laws to protect the natural resources. But with the implantation of incentive programs which aim the economic growth at any cost, with modern farming practices and the expansion of agriculture and cattle raising, great losses occurred to the preservation and conservation of the natural resources. The driving question for th

8. Uso das terras e legislação ambiental: a microbacia do Ribeirão Sapé no município de Caldas Novas (GO) / Land use and environmental legislation: the micro-basin of the municipality of Ribeirão Sapé in Caldas Novas (GO)
A partir da década de 30, o Brasil criou várias leis para a proteção dos recursos naturais. Mas com a implantação de programas de incentivo voltados ao crescimento econômico a qualquer custo, com práticas modernas de cultivo e a expansão das atividades agropecuárias, ocorreram grandes prejuízos para a preservação e conservação dos recursos nat

9. MAPEAMENTO DE ÁREAS ÚMIDAS E BANHADOS NA MICROBACIA DO RIO AMANDAÚ, REGIÃO NOROESTE DO RIO GRANDE DO SUL / MAPPING OF MOISTURE SOIL AND WETLANDS IN THE WATERSHED OF THE AMANDAU RIVER, NORTHWEST REGION OF RIO GRANDE DO SUL
The wetlands are one of the worlds most productive places, with high rates of biological diversity and also highly impacted. In this context, this project was aimed at mapping the Wetlands Ecosystems present in the soil moisture in the watershed of the Amandau River (Watershed U30), using orbital images and clinographic terrain maps. This research was struct

10. Transcriptional networks reconstruction: identification of genes involved on cattle response to tick Rhipicephalus (Boophilus) microplus infestation.
In tropical countries, losses caused by tick infestation in cattle lead to a great impact on animal production systems. Weight and feed conversion reduction, together with diseases transmitted by the parasite are some of the problems that lead to economic losses of billion dollars a year. In a general way, Bos taurus indicus cattle are less susceptible to in

11. Identificação e mapeamento de pastagens degradadas nos municípios de Corguinho e Rio Negro, MS, utilizando fusão de imagens CBERS-2B (CCD e HRC).
A degradação das pastagens pode ser definida como um processo evolutivo de perda de vigor, produtividade e capacidade de recuperação natural constituindo atualmente um dos maiores problemas para a pecuária brasileira. Estudos recentes apontam resultados promissores para identificar e mapear diferentes níveis de degradação em pastagens através de ima

12. Produtividade e eficiência de sistemas de ciclo completo na produção de bovinos de corte / Productivity and efficiency of production in beef cattle production systems
O objetivo do trabalho foi avaliar os impactos da taxa de natalidade, da idade de acasalamento e da idade de abate na produção por hectare e na taxa de desfrute de sistemas de ciclo completo de bovinos de corte e desenvolver um indicador para determinar a eficiência bioeconômica da atividade. Para avaliar estes impactos, utilizou-se um modelo computacion
