15. Assessment in the global warning context : case study Monjolinho rural basin, Piracicaba, São Paulo, Brazil / Avaliação de cenarios no contexto do aquecimento global : estudo de caso da bacia rural do Monjolinho, Piracicaba-SP
One of the global warming effects is the increase of extreme rainfalls, which can cause many negative impacts to rural areas, such as floods and erosion. So, it is important that an equitable land use is distributed along river basins, especially in the ones where there are agricultural fields, since it can help to minimize runoff and soil erosion caused by

16. Modelo de predicción de riesgo de daño de la mosca pinta Aeneolamia postica (Walker) Fennah (Hemiptera: Cercopidae)
This paper evaluated the risk that Aenolamia postica (Walker) Fennah populations reach the economic threshold in sugar cane fields in Veracruz, México. A risk deductive model was constructed to include the sequence of events leading to damaging populations, considered the top event or critical failure in the crop. Model events were identified and quantified

17. Biological and mannering studies of Migdolus fryanus (Westood, 1863) (Coleoptera: vesperidade) and its interaction with entomopathogenic nematodes and other agents of mortalities / Estudos biologicos e comportamentais de Migdolus fryanus (Westwood, 1863) (Coleoptera : vesperidae) e sua interação com nematoides entomopatogenicos, e outros agentes de mortalidade
During de present study biological and morphological data of Migdolus fiyanus (Westwood, 1863) (Coleoptera: V esperidae) were obtained. Males and females after mating were collected in sugar cane field and brought to the laboratory for morphological and biological investigations. Females were individualized in plastic containers ( 20 L). The dimensions were

18. Análise da fragmentação de áreas de vegetação natural e semi-natural do município de Santa Cruz da Conceição, São Paulo, Brasil.
Habitat fragmentation has three major components, namely loss of the original area and reduction in size and increasing of patches. This process was helped with the development of biogeography theory, metapopulation dynamic and sink and source model. This study analyzed the landscape dynamic of the municipality of Santa Cruz, São Palo State, Brazil to base

20. Aplicação de geoprocessamento para o aumento da eficiência de percurso em operações agrícolas na cultura da cana-de-açúcar (Saccharum spp.). / Aplication of geoprocessing for increase the way eficient on the agricultural machines operations on the sugar cane (Saccharum spp.) crop.
The use of machines and agricultural implements in cultures annual or semi-perennial in Brazil is one of the factors that more demands financial resources, due to the cost in fuels, labor and machinery depreciation. Besides, if badly used, can happen environmental damages, such as erosion and compacting soil. Precision Agriculture is growing in Brazil and it

23. Mapeamento do palhiço enfardado de cana-de-açúcar (Saccharum spp.) e do seu potencial energético. / Sugar cane (Saccharum spp.) bailed trash yield and energetic potencial mapping.
Brazil is a developing tropical country with abundant potential for production of biomass. The sugar cane is primarily produced to obtain alcohol and sugar. Currently the sugar cane fields are burned as a pre-harvest practice. If such practice is abandoned, the trash (green leaves, tops and straws left after harvesting) could be collected and used for vapor
