This article extends the analysis of the impact of a system of protein premiums and discounts to that on a farmer's planned production. Despite an unambiguously negative impact on expected pro¢ts of equally likely premiums and discounts, supply response to the introduction of such a system is shown to depend on the level of seasonal variability faced by the farmer. In particular, farmers in reg...

Distinguished hosts, colleagues, Crawford Fund Chairman Tim Fischer, Professor Derek Tribe, and Tim Besley, President of ATSE, I am honored to speak with you today on the occasion of receiving the first Derek Tribe Award from the Crawford Fund. My own institution, CIMMYT (the International Maize and Wheat Improvement Center), and the farmers for whom CIMMYT works, are greatly indebted to Profes...

This paper estimates optimal hedging ratios for a Finnish spring wheat producer under price and yield uncertainty. The contract available for hedging fixes the price and quantity at the time of sowing for a delivery at harvest. Autoregressive models are used to obtain point forecasts for the conditional mean price and price volatility at harvest. Expected yield and yield volatility are estimate...

Water erosion and runoff can be severe due to poor infiltration through frozen soil in the dryland wheat (Triticum aestivum L.) production region of the inland Pacific Northwest (PNW), USA. For more than 70 years, farmers and researchers have used various methods of subsoiling to reduce runoff and erosion and to improve infiltration and soil moisture storage. The practice and equipment have evo...

INTRODUCTION Occupational exposure to grain dust causes respiratory symptoms and pathologies. To decrease these effects, major changes have occurred in the grain processing industry in the last twenty years. However, there are no data on the effects of these changes on workers' respiratory health. OBJECTIVES The aim of this study was to evaluate the respiratory health of grain workers and far...

Rice–wheat cropping system is very common in India. It contributes to over 70% of total food grain production in the country with an area of 12 M ha under this cropping system. However, it is estimated that under rice and wheat crops separately the area is 42.31 and 22.98 M ha respectively. Looking to the above facts a study at farmer’s field of Ambedkar Nagar district was under taken to evalua...

Background: The agricultural sector is one of the most important sectors in production. The safety and health of farmers are important factors that can cause a significant increase in efficiency and productivity. The aim of this study was the assessment of musculoskeletal disorders (MSDs) using the OVAKO Working Posture Analysis System (OWAS) and evaluation of the effect of ergonomic training o...

Background: Renewable energy (RE) production is a land-use driver with increasing impact on landscape configuration and a matter of controversial debate. Woody biomass cropping provides an opportunity to interlink RE supply with spatial planning goals, RE concepts and rural development programmes since it tackles several issues, ranging from climate or soil protection to over food production an...
