The South Central Farm (SCF) in Los Angeles was a 14-acre urban farm in one of the highest concentrations of impoverished residents in the county. It was destroyed in July 2006. This article analyzes its epic as a landscape of resistance to discriminatory legal and planning practices. It then presents its creation and maintenance as an issue of environmental justice, and argues that there was a...

Population Viability Analysis (PVA) is an appropriate, scarcely used tool to assess potential impacts on population dynamics of man-induced mortality. Therefore, the study of Carrete et al. (2009) is a valuable contribution to the assessment of the impact of wind-farms on birds due to collision mortality. Nevertheless, the results and conclusions presented by the article could create confusion ...

Major sustainability challenges in agricultural landscapes include the loss of biodiversity, soil erosion from wind and water, and increasing rates of salinity. Other than relatively few exceptions such as the listing or enlargement of nature reserves and the establishment of large corridor plantings (e.g. biolinks in Australia), addressing these challenges generally occurs at the paddock scale...

The farm planning problem is a critical aspect in the design of decision support systems (DSSs) for complex farm advising. Traditionally, the approaches to this problem have been very simple and unable to manage the complexity of the problem, which involves scheduling of field tasks, investment analysis, machinery selection, cost/benefit analysis, and other aspect of the agricultural production...

The Extension Service, United States Department of Agriculture, funded a special project to approach development of extension materials for dairy farmers by systems analysis. Agricultural engineers created video tapes and publications on manure, feed handling, calf housing, and milking subsystems. Dairy scientists created slide-tapes and publications on controlling feed losses during harvest, s...

Crops are harvested by performing a series of operations with harvesting vehicles in the field. The harvest operation is performed with combines (harvesters). Supporting logistical activities of transferring and transporting harvest (grain) from the field to the farm are carried out with the help of tractors. This research focuses on detailed logistics planning of various infield harvest operat...
