| RESUMO Estimativas da emissão de metano em sistemas de cultivo de arroz sob condições de manejo de inundação foram realizadas para o estado de São Paulo, no período de 1992 a 2009, utilizando os Documentos Orientadores (Guidelines) sobre a Elaboração de Inventários de Emissão de Gases de Efeito Estufa do IPCC de 2006. Os resultados mostram emissões totais 45% inferiores às obtidas no Inventário Estadual de Emissão de Gases de Efeito Estufa, o qual se baseou em método anterior do IPCC 1996 para o período de 1990 a 2008. Em 2000, o total de emissão de metano pelo cultivo de arroz no estado de São Paulo foi estimado em 2,72 Gg, sendo 98% provenientes de sistemas irrigados por inundação e 2% de sistemas de várzea. Até 2008, as emissões de metano foram... |

| Background: In order to evaluate the variation among different rice types, the genetic diversity in a rice collection composed by 59 breeding lines, 23 landraces, 18 weedy rice lines, and 35 introduced lines that collected from countries worldwide was analyzed using 134 simple sequence repeat markers. Results: In total, 1264 alleles were identified (average, 9.43 per locus). Rare alleles made up a large portion (58.4%) of the detected alleles, and 29 unique alleles associated with rice accessions were also discovered. A model-based structural analysis revealed the presence of three subpopulations. The genetic relationships revealed by the neighbour-joining tree method were fairly consistent with the structure-based membership assignments for most of the... |

| O desenvolvimento economico do pais no decenio de 1970 a 1980, a melhoria da renda "per capita", o crescimento populacional e o aumento das exportacoes foram alguns dos fatores que determinaram a crescente producao de alimentos. Esse incremento na disponibilidade de produtos agricolas, decidiu-se a epoca, teria que ser feito via aumento da produtividade nas areas agricolas tradicionais e da abertura de novas areas de producao. A regiao dos cerrados, com 238,6 milhoes de hectares, apresenta-se com excelente potencial para a segunda opcao. Dispoe de razoavel infra-estrutura viaria e esta proxima dos grandes centros consumidores. Estes centros recebem, constantemente, significativo fluxo migratorio rural-rural, oriundo, sobretudo, do sul do Pais e dispoe de... |

| At first glance, the compatibility of social theory and resilience thinking is not entirely evident, in part because the ontology of the former is rooted in social interactions among human beings rather than ecological process. Despite this difference, resilience thinking engages with particular aspects of social organization that have generated intense debates within social science, namely the role of humans as integral elements of social-ecological systems and the processes through which given social structures (including material relations) are either maintained or transformed. Among social theoretical approaches, Actor-Network Theory (ANT) is noted for its distinctive approach to these aspects. ANT proposes that human and nonhuman components (both... |

| The study conducted in the state of Manipur, has identified the factors affecting monocropping of rice as the cropping intensity of the state is only 107 per cent. Multistage random sampling has been followed to select the districts, blocks, villages and finally the farmers and logit model has been used for the analysis. The study has observed that availing of institutional credit and educational level are among the important factors which decrease monocropping. The study has highlighted the need for focus on crop diversification and increasing cropping intensity. Strengthening of co-operative societies, increasing availability and accessibility to credit facilities, increasing awareness about new technologies, etc. will help in increasing the cropping... |

| Shortage of labor during the harvest season is one of the problematic situations for farmers in the Malaysian paddy fields. Thus, combine harvester has been utilized massively in Malaysian paddy field for the purpose of assisting the farmers to overcome the problems. Majority use of combine harvesters in the country was provided by the state farmers’ organization that offers custom operators to be hired by the farmers during harvesting seasons. A case study was conducted to identify and rank the factors that affect farmers’ current satisfactions with mechanized harvesting using combine harvesters that offered by custom operators. A group of farmers comprising of 336 respondents at rice granaries in Tanjung Karang district, Selangor, Malaysiawas chosen... |

| First records of Glyphepomis adroguensis (Hemiptera, Pentatomidae) and its parasitoid, Telenomus podisi (Hymenoptera, Platygastridae), on rice fields in Rio Grande do Sul, Brazil. Eggs, nymphs, and adults of Glyphepomis adroguensis Berg, 1891 (Hemiptera, Pentatomidae) were observed for the first time on rice fields (Oryza sativa L.) in Charqueadas (29º59'S, 51º31'W) and Eldorado do Sul (30º02'S, 51º23'W) of Rio Grande do Sul state, Brazil. Telenomus podisi Ashmead, 1893 (Hymenoptera, Platygastridae) was found in G. adroguensis eggs. |

| Conflict between the short run welfare of poor consumers and agricultural production incentives creates some of the most difficult policy issues facing developing countries. Resulting policy option constraints are particularly severe in very low income countries. The conflict may on the one hand impede the growth in al production essential to improve long term welfare of low income consumers, and on the other hand restrain policies to increase consumption, which in the long run is essential to the success of the measures taken to increase production. The widely observed phenomenon of urban bias in food price policy is itself a product of the nature of low income societies and of this complex conflict. This research by Raisuddin Ahmed delineates and... |
