Soil erosion research in New Zealand has focused on the on-site costs of soil loss in the form of production loss and storm damage. Subsidization and implementation of soil conservation measures have primarily been justified through maintenance or improvement of farm productivity levels. The shift in responsibility for soil conservation management and damage remedies from national to regional government has highlighted public good issues raised by soil erosion. This paper develops an inventory and assessment of the relative magnitude of the impacts of soil erosion and sedimentation in New Zealand. It also provides an estimate of the total economic costs of these impacts based on the limited data available. The impacts of greatest economic significance are... |

O trabalho teve como objetivo estimar a safra paranaense, que somando as culturas da soja e do milho foi recorde chegando em 2007/08 a 21,2 milhões de toneladas, aliado a isso tem-se uma situação favorável de preços internacionais, que gera resultados positivos para o setor produtivo e permite a recuperação do setor que passou por anos complicados por problemas climáticos e de preços. A estimativa da safra foi realizada com uma amostra de dados que representam 78% da área de soja e 61% da área de milho do Estado do Paraná. Quanto as questões relacionadas a biotecnologia – soja transgênica – RR, os resultados foram os esperados, de que essa é mais uma tecnologia disponível ao produtor e esta evoluindo para ser cada vez mais competitiva com a soja... |

In-depth field research—undertaken by IFPRI with the Food and Agriculture Organization of the United Nations (FAO) and other partners in India, Kenya, and Mali—brings to light new evidence about farmers’ access to seed and the role of village markets in supplying it, with a focus on semi-arid environments.1 The findings point to several policy options aimed at improving the effectiveness of these markets, which can be crucial for reducing the potential negative impacts of high food prices. Such options might be considered in tandem with those recommended for more favorable environments, where seed systems already function more effectively. This brief introduces the issues that drove this research project, relevant concepts, and methods. The accompanying... |

Private and many publicly funded plant breeding organisations charge farmers for use of varieties they develop. This article compares four alternative charging mechanisms and outlines responses to these alternatives by farmers and plant breeders. Risk‐averse farmers and breeders are shown to have opposite preferences for charging mechanisms. Results suggest profit‐based or royalties are preferred by farmers whereas breeders prefer area or tonnage‐based royalties. Risk‐sharing arrangements between both parties could lead to an overall preference for profit‐based or royalties. However, this finding is subject to important caveats and practical limitations. |

This report evaluates the U.S. and world sugar markets for 2000-2010 by using the Global Sugar Policy Simulation Model. This analysis is based on assumptions about general economic conditions, agricultural policies, population growth, weather conditions, and technological changes. Both the U.S. and world sugar economies are predicted to improve over the next ten years after the current over supply is reduced. World demand for sugar is expected to grow faster than world supply, resulting in gradually increasing Caribbean sugar prices from 8.51 cents/lb in 2000 to 12.67 cents/lb in 2010. The U.S. wholesale price of sugar is projected to increase from 22.5 cents/lb in 2000 to 26.6 cents/lb in 2010, if the United States maintains its sugar programs. World... |

Statistical methods are used to study relationships between research expenditures (adjusted for inflation) made from producer checkoff programs and soybean yields and net revenues in the United States for the years 1978 – 2007. Results presented are for yield and net revenue data and research expenditures for the entire United States. We find that research expenditures over the years 1994 to 2007 are responsible for a 0.95 bushel per acre per year increase in soybean yields. We calculate net producer revenues to be about $17 per acre higher than would have been the case without the soybean research checkoff expenditures. |

In this paper, relationships between U.S. and Canadian wheat prices are examined using cointegration and error correction approach. The use of an error correction model is appropriate because U.S. and Canadian wheat prices are first differenced stationary and cointegrated. The results suggest that both U.S. durum and hard spring wheat prices respond to restore the equilibrium relationship with the corresponding Canadian price while the Canadian price does not respond to restore equilibria. That is, the structure of the respective policies is such that Canadian markets are largely insulated from influences flowing from the United States while U.S. markets are not insulated from Canadian influences. These results could be interpreted to support the... |

This report examines current trends in the U.S. grain industry. Many identity preservation(IP) grain systems have emerged recently, driven by a confluence of supply and demand factors. IP grain requirements for specific production protocols, marketing channels, and quality assurance depend on whether the crops are trait-specific, non-GM (genetically modified), organic, or pharmaceutical. Cost structures vary according to the relative importance of segregation and risk management. High information management, greater market coordination, and frequent reliance on contracts characterize IP grains. IP grain markets are also inherently riskier, with volatile supply, inelastic demand, and fluctuating price premiums. Increasing grain differentiation is altering... |

No-till (NT) has been shown to reduce fuel, labor, and machinery costs compared to conventional-till (CT) but very few rice producers in Arkansas practice NT. The low adoption rate is most likely due to difficulties in management but also limited information on the profitability and risk of NT. Most rice producers are knowledgeable on NT costs savings but consider it less profitable due to yield reductions offsetting costs savings. This study evaluates production costs, crop yields, and economic risk of both NT and CT in five rice-based cropping systems (continuous rice, rice-soybean, rice-corn, rice-wheat, and rice-wheat-soybean-wheat). Yields, crop prices, and key input prices are simulated to create net return distributions. Stochastic efficiency... |

Irrigation vegetable farmers in Seymour District, Eastern Cape, have had problems concerning market access. Initial action by the researcher showed that problems can be solved. A survey showed younger farmers to be better educated, more businesslike and more eager to solve problems than older farmers. The unavailability of transport, poor infrastructure, lack of market information and to a lesser extent, dishonesty of some traders are major problems for these farmers. The community involved should be regarded as progressive, and can be expected to prosper once their problems have been solved. |
