| This study was conducted to gain an understanding of how small-scale farmers in Mbeya District have adopted improved wheat technologies promoted by the wheat research program at MARTI-Uyole. The specific objectives were to assess farmers’ wheat management practices, determine the technical and socioeconomic factors affecting the adoption of improved wheat technologies, and draw implications for research, extension, and policy. A purposive multistage sampling procedure was used to select 202 farmers, 160 from Tembela Division and 42 from Isangati Division, which are two important wheat-growing areas in Mbeya District. Primary data were collected using structured questionnaires and supplemented by secondary information obtained from MARTI-Uyole. Juhudi was... |

| Maize is the major food crop grown in the coastal region of Kenya and constitutes a major component of the diet of the population in the region. However, average yields are far below the potential for the region and low production levels create serious food deficits. Over the years, new technologies have been introduced but adoption has remained low, especially for fertilizer. This paper examined current maize-farming practices and technological and socioeconomic factors that influenced adoption in the Kilifi and Kwale Districts of the Coast Province, that together account for half of maize production in the region. The study found low adoption levels for improved maize varieties and technology, especially fertilizer, among farmers in the area. Farmers... |

| The publication describes outcomes of a study to assess the effectiveness of a large-scale crop seed relief effort in Zimbabwe during 2003-07. Aims of the effort, which was supported by the British Department for International Development (DfID) and coordinated by the Food and Agricultural Organization (FAO) regional office in Harare, included broader diffusion of open-pollinated maize varieties (OPVs), as opposed to hybrids. Based on the findings of the study, the authors recommend that, to increase benefits to vulnerable groups, participants in such efforts should effectively disseminate information on selecting and recycling seed, supported by training and field demonstrations, and should target relatively well-endowed farmers initially. Recommendations... |

| O objetivo deste trabalho foi avaliar a eficiência energética de sistemas especializados e mistos de produção de grãos e carne e o balanço energético na produção de bioenergia. Foram avaliados dados de 20 anos de cultivo com sistemas agrícolas especializados e mistos. Como sistemas agrícolas especializados, avaliaramse: a pastagem de gramínea; a pastagem de gramínea consorciada com leguminosa; e a produção de grãos em sistema plantio direto ou em sistema convencional de preparo do solo. Como sistema misto, considerou-se a integração lavoura‑pecuária em dois sistemas de manejo. Os insumos utilizados foram considerados como o ingresso energético, enquanto a produção de grãos e carne, as saídas de energia. Os produtos agrícolas nos sistemas mistos... |

| O Brasil e um dos paises com maior diversidade genetica, respondendo por cerca de 30% das plantas e especies animais que ocorrem no mundo. Dentre os diferentes biomas brasileiros, os Cerrados, com seus 207 milhoes de hectares, apresenta uma grande diversidade faunistica e floristica em suas diferentes fisionomias vegetais. Ate meados deste seculo esta regiao era considerada como marginal para producao agricola, no entanto, devido ao desenvolvimento da pesquisa e de tecnologias agricolas que viabilizaram sua utilizacao em bases economicas, hoje ela e responsavel pela producao de cerca de 35% de graos e carnes do pais. O modelo de ocupacao da terra utilizado, baseado no uso intensivo de insumos e maquinas pesadas, se de um lado, no ultimos vinte anos,... |

| The amount of energy and food consumed in Puerto Rico is more indicative of a developed nation than one than is underdeveloped. All the energy consumed in Puerto Rico is from fossil fuels, while the agricultural sector marginally provides the needs of the consumer. In addition, the animal production sectors rely exclusively on imported feedstock for the preparation of feeds. There is a potential to develop an ethanol industry based initially on sugarcane, as the main feedstock and then turn to biomass from energy cane and or organic solid waste in the future. In order to move to the second generation of ethanol production, the cellulosic ethanol industry has to become economically viable. A limiting factor in the use of sugarcane is that only 40,000 ha are... |

| On the strength of expounding the general situation of study area and the status quo of agricultural laborers in China, the changes of the scale and structure of them from 1985 to 2009 are analyzed by relying on the survey from farmers and statistical data from the government. The causes of these changes are analyzed from the aspects of rural farmland policy，birth-control policy, farmland marginalization and industrialization. Based on the study on the causes, the impacts of the changes on food production are analyzed from operation scale of household, the grain cropping area, the multi-cropping index and land productivity. The results show that the quality of agricultural laborers is decreasing form 1985 to 2009, which is characterized by the lack of... |

| A produção agrícola dos segmentos sociais contemplados neste capítulo - agricultores familiares, povos indígenas e populações tradicionais - tem características, significados e desafios distintos dos demais segmentos produtivos do setor agrícola brasileiro. Demandam diagnósticos e reflexões adequadas quanto ao seu significado nas diferentes realidades econômicas, sociais, políticas, culturais e ambientais para, assim, poder abordar estratégias de aumento de produção. |

| In contrast to the increasing use of GM plants in world-wide agriculture, the acceptance of GM food is still low in the European Union (EU). In order to ensure freedom of choice for consumers and users of GM and non-GM products, GM food and feed products have to be labeled in case a tolerance threshold of 0.9 % is exceeded for EU authorized GMOs. This paper aims to quantify the cost of traceability and co-existence systems for GM food from the seed to the food level for sugar, wheat starch and rapeseed oil for human consumption in Germany respecting the 0.9 % threshold for labelling of GM food. The cost calculation for traceability and co-existence measures follows the principle of aggregating all incurred cost on the different levels of the value chain... |

| O objetivo deste estudo é analisar a dinâmica da produção de arroz no Maranhão no período de 1975 a 2010. Utilizaram-se dados de séries temporais de 1975 a 2010 (2012 para médias estaduais), com valores de área colhida, produção e produtividade, realizando-se as seguintes análises: distribuição de frequência; medidas de concentração; distâncias com entidades geográficas; análise de agrupamentos; e taxa de crescimento anual. No Maranhão, a cultura do arroz apresentou taxa de crescimento negativa para a produção, área colhida e produtividade, no período de 1975 a 2010. Em relação aos municípios, em 2010, maiores valores de produtividade foram obtidos nos municípios de Arari e Vitória do Mearim; de produção em Santa Luzia e Grajaú; e de área colhida em Barra... |
