| Livestock is recognized as one of the major drivers of current and future global change. This is caused on the production side, by the substantial resource requirements (land and water) per unit of output, and the related greenhouse gas emissions, and on the consumption side, by the growing demand due to population and economic growth. Our paper investigates whether productivity gains which enabled to the crop sector to satisfy the increased demand under decreasing real prices, and with little additional land, in the past decades, can be expected in the livestock sector in the future. To answer this question, we implement the recursively dynamic partial equilibrium bottom-up model of the global agriculture and forest sectors (GLOBIOM), expanded by a newly... |

| There is considerable interest in projections of future productivity growth in agriculture. Whether one is interested in the outlook for global commodity markets, future patterns of international trade, or the interactions between land use, deforestation and ecological diversity, the rate of productivity growth in agriculture is an essential input. Yet solid projections for this variable have proven elusive particularly on a global basis. This is due, in no small part, to the difficulty in measuring historical productivity growth. The purpose of this paper is to report the latest time series evidence on total factor productivity growth for crops, ruminants and non-ruminant livestock, on a global basis. We then follow with tests for convergence amongst... |

| The study was initiated with the objectives of elucidating and analyzing potentials, weaknesses, opportunities, constraints and policy options in the development of feed crop farming with an emphasis on secondary crops in Southeast Asian developing countries. In Malaysia, feed crops currently not much to employment, income generation, import substitution and export promotion because the sub-sector is small. The scope of the study is limited to the dominant non-ruminant sector of the livestock industry. This sector, particularly poultry and swine, has not only experienced rapid growth but also produces more than is required for domestic consumption and thus exports to neighbouring countries. |

| The objective of the study was to analyze the trends of demand and supply for animal feeds including the factors that determine production and consumption of feed crops. Other objectives are: (1) To evaluate potentials and constraints for expanding feed crop farming; and (2) To formulate recommendations for policy options to promote the sustainable development of feed crop farming. The method of study involved the collection of data through rapid rural appraisal and group discussions with stakeholders, including livestock farmers, scientists and feed manufacturers. There was interaction with policy makers and planners related to feed crop production, feed prices and production of livestock products. Secondary data on population, income, prices, consumption... |

| Many of the Groups supported had humble origins. Some were originally formed by women who got together because of their desperate situation and started 'merry go rounds' by which they each contributed a small amount of money each month and then supported members in turn either in a crisis situation or for a particular need - eg school fees. As they developed self confidence and improved their well being in a small way, so ngos such as SACHKWR have been able to build on their strengths and support them in the next step towards self sustainability. The challenge now is to ensure that as SACHKWR move on and support other communities that they are able to continue on their own with the minimum of outside support. To this end it is hoped that one of the SACHKWR... |

| Com um efetivo bovino estimado em 200.000 cabeças, cerca de 7% da região norte, a bovinocultura do Estado do Acre experimentou um acentuado desenvolvimento na última década. Entretanto, nos últimos cinco anos, a sua capacidade de financiamento foi substancialmente reduzida, principalmente, por não ter sido privilegiada na alocação de investimentos e na absorção de novas tecnologias geradas. Um grande entrave ao desenvolvimento da pecuária tem sido o suporte alimentar dos rebanhos, constituídos de pastagens cuja qualidade de forragem produzida são seriamente comprometidas por práticas inadequadas de formação e manejo, incidência de pragas e doenças, e pela estação seca, quando se obtém rendimentos extremamente baixos. Com este documento, a UEPAE/Rio Branco... |

| This paper examines the direct, first-rounds impact of two types of remittances—internal and external remittances—on income distribution and asset accumulation in rural Pakistan. Using income decomposition techniques on a three-year panel household data set, the paper finds that internal remittances have a positive effect on equity and that external remittances have a negative effect. The study also uses an asset-accumulation model to pinpoint the effect of remittances on five types of rural assets: irrigated land owned, rainfed land owned, livestock assets, agricultural capital, and nonfarm assets. The results show that remittances do have an effect on rural asset accumulation. While external remittances have a positive and significant effect on the... |

| In Southern Patagonia, most of the land ranging from the mountains to the sea in contrasting environmental conditions is devoted to extensive sheep farming. Existing estimations indicate that in ecosystems under livestock use, around 85% of the nitrogen (N) returning to the soil is through animal feces and urine. However, there is a lack of information concerning the rate of nutrient return into the soil from animal feces in Southern Patagonia. In this study, we evaluated the rate of sheep faeces decomposition and nutrient (N, P, Ca and K) release in three different ecological areas of Southern Pat agonia, representing a West to East environmental gradient. Samples of fresh sheep dung were collected in the field, processed in the laboratory and located in... |

| Segundo o Painel Intergovernamental sobre Mudança do Clima, os eventos extremos que vem sendo observados nas últimas décadas e aqueles previstos para o futuro, são uma consequência das mudanças climáticas em função das atividades humanas. Independente da causa, mudanças climáticas ou variabilidade climática natural, eventos extremos ocorrem eventualmente e causam preocupação na sociedade, devido ao risco de perdas de vidas humanas, de propriedades e econômicas. Medidas de adaptação às mudanças climáticas são fundamentais para minimizar os riscos. |

| Este documento apresenta análise de caso real do processo de intensificação sustentável realizado no Pantanal. Estando a segurança alimentar no topo da discussão da agenda global, a demanda por alimentos aumenta à medida que as populações crescem, e enriquecem, o que permite o acesso a dietas mais variadas. Por outro lado, há uma maior concorrência por terra, água, energia e outros insumos na produção de alimentos. O conceito de intensificação sustentável pressupõe maior produção por meio de maior eficiência no uso de recursos, reduzindo o impacto negativo no meio ambiente, e oferece oportunidades para aumentar a produção por unidade de área, empregando tecnologias, que considerem os três pilares de sustentabilidade (planeta, pessoas e lucro). Identificar... |

| The concentration and size distribution of airborne particles were measured inside and outside typical animal houses such as broilers, broiler breeders (both floor housing with litter); layers (floor housing system and aviary housing system); turkeys (floor housing with litter), pigs: fattening pigs (traditional houses, low emission houses with dry feed, and low emission houses with wet feed), piglets, sows (individual and group housing); cattle (cubicle house), and mink (cages). Using an aerosol spectrometer, particles were counted and classified into 30 size classes (total range: 0.25 – 32 µm). Particles were measured on for two days, one in spring and the other in summer, in two of each species/housing combination during 30 min inside and outside the... |

| The purpose of this survey was to evaluate the socioeconomic and technical assistance profiles of dairy farmers from six districts in the south of Minas Gerais state, Brazil, and to identify the possible risk factors associated with total milk bacteria count (TBC) above 43,000 CFU mL-1 and bulk milk somatic cell count (BMSCC) above 595,000 cells mL-1. Most of the producers were between 41 and 60 years of age (48.9%), 74.2% did not reach high school, and 72.3% of the respondents were satisfied with their profession, although 63% would not recommend dairy farming to their children. Only 34.7% used periodic technical assistance, but 59.1% consulted it in cases of doubt. The risk factors found in the final multivariable regression models were: TBC (Did not... |
