| Este artigo analisa a evolução, no período 1992-2006, do rendimento das pessoas empregadas em empreendimentos cuja atividade principal é uma lavoura, destacando-se cana-de-açúcar, banana, café, soja e milho, utilizando dados da PNAD. Verifica-se que o crescimento do rendimento dessas pessoas no período 2001-2006 está fortemente correlacionado com a variação do salário mínimo real. Em seguida, usando dados do IEA/CATI, analisa-se a evolução da remuneração obtida no estado de São Paulo, de 1995 a 2007, nas empreitas de colheita de cana, laranja, limão, tangerina, café em coco, café cereja e algodão. Esses dados também indicam crescimento das remunerações por dia a partir de 2001. Para a maioria das culturas analisadas observa-se uma tendência de crescimento... |

| There is ample evidence to suggest that Sri Lanka’s climate has already changed. However, the bigger question of national importance is what Sri Lanka’s climate will look like in 50 or 100 years and how prepared the country is to face such changes. This report reviews the status of climate change (CC) research/activities in Sri Lanka in terms of observed and projected climatic changes, their impacts on water resources and agriculture, CC mitigation and adaptation, and research needs. The study also developed a pilot level CC Vulnerability Index, which was subsequently mapped at district level. The maps indicate that typical farming districts such as Nuwara Eliya, Badulla, Moneragala, Ratnapura and Anuradhapura are the most vulnerable to CC due to their... |

| We quantify the emergence of biofuel markets and its impact on U.S. and world agriculture for the coming decade using the multi-market multi-commodity international FAPRI model. The model incorporates the tradeoffs between biofuel, feed, and food production and consumption and international feedback effects of the emergence through world commodity prices and trade. We examine land allocation by type of crop, and pasture use for countries growing feedstock for ethanol (corn, sorghum, wheat, sugarcane, and other grains) and major crops competing with feedstock for land resources such as oilseeds. We shock the model with exogenous changes in ethanol demand, first in the United States, then in Brazil, China, EU, and India, and compute shock multipliers for... |

| This paper extends the long-term cash-flow simulations reported in Part I (Hutchings 2009) to include a range of seasonal scenarios at four representative dryland sites in south-eastern Australia. The effect of varying the proportion of sheep and cropping in the enterprise mix at each site on cash surpluses is discussed. The analysis shows that, for most sites, the cropping enterprises require better than average seasons, prices and water-use efficiencies to generate a positive cash flow and are subject to substantial variability and risk of loss. In contrast, the sheep enterprises show small but stable cash flows in all but extreme drought conditions. This paper emphasises the need to include site-specific, long-term variability and whole-farm costs in... |

| The paper develops the concept of return to scale at an elementary level, but rigorously. It is argued that constant and increasing returns are incompatible with competitive markets, because they imply the convergence to few firms, and this is not the case for the real world. The main point is that average cost curve has the shape of a U, and, without restrictions, the firms converge to the branch of decreasing returns. If on the real world is detected increasing or constant returns, it suggests that it should be looked for the market imperfection that are the base of them. And results of increasing or constant returns of econometric models must be taken as a sign of market imperfections. Yet the knowledge of the market imperfections is crucial to design... |

| The Secretaria de Fomento Agropecuario del Estado de Coahuila created at the express request of rural producers, the program of agricultural and rural extension, in order to lead the field a comprehensive system of technical assistance, supported by technology that generate research institutions , and backed by highly trained technicians, committed to sustainable rural development. Among the main objectives of the program in the case of crops, is raising yields and improve their quality, and in the case of livestock, increase productivity and maintain the health of cattle ranches. The extension program, began in 2006 with two specific programs: one in Cotton, in the laguna region, and another in Bovine, in 23 municipalities of the entity; for 2007, are... |

| This is the seventh in the series of the Centre's publications providing specific and wide-ranging data on coarse grains, pulses, roots and tuber (CGPRT) crops in the humid tropics of Asia and the Pacific. The crop sub-sector dominates the agricultural scenario in Bangladesh. The greater uniformity of the landmass, the fertile alluvial soil and the tropical monsoon climate provide excellent conditions for crop production. If other things remain unchanged, agriculture will continue to play the main role in the growth and stability of the economy of Bangladesh for many years to come. This volume covers time-series statistics of Bangladesh on seventeen CGPRT crops plus two major cereals (rice and wheat) reporting area, production and yield at both national... |

| This study examines the sources of crop income growth in Indian agriculture over the 1980s and 1990s. Using a method developed by Minot (2003), the analysis decomposes crop income growth into the contribution of yield increases, area expansion, price increases, and diversification from low-value crops to higher-value crops. The results confirm that at the national level, technology (higher yield) was the main source of crop income growth during 1980s, while rising prices and diversification emerged as the dominant sources of growth in agriculture during 1990s. Diversification towards higher-value crops such as fruits and vegetables accounted for about 27% of crop income growth in the 1980s and 31% in the 1990s. However, these national averages hide... |
