Government agricultural programs have a variety of goals, among them is preserving the family farm (U.S. Department of Agriculture 2003, pp. 18–20). While no single program is dedicated to maintaining a certain type of farm structure, program features are sometimes designed so as not to disadvantage family farms. For example, dollar limits may be placed on payments that a single person can rece...
With the continuing pressure on Australia’s water resources and interand intra-annual rainfall variability, farmers, especially in rainfed agricultural and pastoral zones, have been developing farm dams as a mean of providing additional water sources for irrigation and stock. The density of farm dams has increased over time, and an accurate knowledge of the spatial distribution of farm dams is ...
Mixed crop-livestock systems, combining livestock and cash crops at farm level, are considered to be suitable for sustainable intensification of agriculture. Ensuring the survival of mixed crop-livestock systems is a challenge for European agriculture: the number of European mixed crop-livestock farms has been decreasing since 1970. Analysis of farming system dynamics may elucidate past changes...
Farmland is a major land cover type in Europe and Africa and provides habitat for numerous species. The severe decline in farmland biodiversity of the last decades has been attributed to changes in farming practices, and organic and low-input farming are assumed to mitigate detrimental effects of agricultural intensification on biodiversity. Since the farm enterprise is the primary unit of agri...
In this paper, the risk profile of two pastoral production systems in New Zealand are examined. All farmers must manage and mitigate a multitude of risks. Traditionally, a farm budget is solely undertaken to satisfy a lending institution. Limited variance analysis takes place, usually for output prices and inputs such as: interest rates, energy costs, and fertiliser. The authors of this paper u...
The food preferences of 64 cats, of which 28 were domestic pets and 36 were free-ranging animals on three farms, were tested using five food types; a sixth type was also tested on the farm cats. Information was also gathered on the background diet of the house cats (individually) and of each farm cat colony. Consistent differences were found between the predefined groups of cats in their prefer...
The STAR level-3 trigger is a MYRINET interconnected ALPHA processor farm, performing online tracking of N 53!#, 58000 particles (N 10*/5 445 per track) with a design input rate of R"100 Hz. A large-scale prototype system was tested in 12/99 with laser and cosmic particle events. ( 2000 Published by Elsevier Science B.V. All rights reserved.
To the careless observer and general critic the making of a law is a very easy thing. But to the actual lawmaker who meets the usual difficulties and encounters the practical obstacles it is a very different matter, and it may be of interest to many to follow the course of a bill from beginning to end. In the first place it may be said that the legislature is only the "machine" through which la...
The purpose of this study was to investigate the biological and genetic characterization of persistent Salmonella isolates in an integrated broiler chicken operation, in an attempt to elucidate the source of contamination. From the breeder farm, the hatchery, the broiler farm and the chicken slaughter house of an integrated broiler chicken operation, a total of 6 serotypes were observed. Althou...
A farmer’s choice to make an on-farm investment programme can be modelled as a discrete choice amongst finite alternatives. The idea of this paper is to test the possibility of using discrete choice models in the field of the evaluation of structural policies. Farmers choose to take part into agricultural programmes according to their preferences, and farm structural and economic characteristic...
