INCE 1974, FOLLOWING PUBLICATION of Schuh’s “The Macroeconomics of Agriculture,” much research effort has been devoted to determining whether and how monetary policy affects the farm sector. One of the more active areas of interest has been the question of whether changes in the money stock affect the farm! nonfarm product relative price ratio. The reason for this particular interest, as descri...

The Austrian example illustrates the potentials as well as the limitations of forest accountancy data networks as devices for investigating and furthering the profitability of small scale farm forestry (SSFF). Special reference is made to the experiences gained in the process of adaptation and renewal of the system of data management and reporting, which took place in the year 2000. The sampled...

Approximately 5% of pigs produced in Australia is believed to be traded at livestock sales. Interviews and focus group discussions were conducted with producers (106 and 30 producers, respectively), who traded pigs at livestock sales. The purpose of the study was to gather information on how producers identified their pigs in order to evaluate how these practices may impact the ability to trace...

High residue conservation tillage systems for cotton (Gossypium hirsutum L.) production have been proposed as having the potential to be both economically and environmentally sustainable, and research regarding till­ age systems has indicated that several advantages may exist for conservation tillage systems compared to con­ ventional tillage systems. However, adoption of new farming systems on...

The fluctuation of active power output of wind farm has many negative impacts on large-scale wind power integration into power grid. In this paper, flywheel energy storage system (FESS) was connected to AC side of the doubly-fed induction generator (DFIG) wind farm to realize smooth control of wind power output. Based on improved wind power prediction algorithm and wind speed-power curve modeli...

The use of shellfish aquaculture for nutrient removal and reduction of coastal eutrophication has been proposed. Published literature has indicated that nitrogen contained in harvested shellfish can be accurately estimated from shell length:nitrogen content ratios. The range of nitrogen that could be removed by a typical farm in a specific estuarine or coastal setting is also of interest to reg...

The farm level is the most appropriate scale for evaluating options for mitigating greenhouse gas (GHG) emissions, because the farm represents the unit at which management decisions in livestock production are made. To date, a number of whole farm modelling approaches have been developed to quantify GHG emissions and explore climate change mitigation strategies for livestock systems. This paper...

Animal agriculture in North America has undergone a revolution since World War II. Productivity has increased enormously through the use of animal confinement, genetic selection, scientific feed formulation, and productivity-enhancing pharmaceuticals. There has been a shift to larger production units taking advantage of economies of scale. Critics contend that these changes have reduced the wel...

This paper presents the particle swarm optimization (PSO) for reactive power and voltage control (Volt/Var Control) in distribution system considering DFIG wind farm. In this paper, the reactive power output of DFIG wind farm has been considered as the control variables in the Volt/Var Control scheme by considering the reactive power compensation capability of DFIG. The minimization of total sy...

The study on gender and net farm income of cassava-based farmers under individual land tenure system was done in Abia State of Nigeria. The main objective was to determine the Net Farm Income (NFI) and the Benefit Cost Ratio (BCR) of the cassava farmers by gender vis-aviz their income levels as well as food security in the state. A multi-stage random sampling technique was adopted while data we...
