AIM To describe the pattern of non-intentional farm-related fatalities in Australia for 2003-2006 and examine trends. METHODS Data from the National Coroners Information System were analysed to define all non-intentional farm injury fatalities for the period. RESULTS The incidence of farm fatalities has declined by 44% over the past 20 years from an average of 146 deaths per year to 82 deat...

targeted extension for heterogeneous farming systems is a challenge in developing countries. farm type identification and characterization based on estimates of income from different farm components allows simplifying diversity in farming systems. use of multivariate statistical techniques, such as principal component analysis (pca) and cluster analysis (ca), help in such farm typology delineat...

Listeria monocytogenes is a significant food-borne human and veterinary pathogen. Contaminated silage commonly leads to disease in livestock, but the pervasive nature of the bacterium can make it difficult to identify the source of infection. An investigation of bovine listeriosis that occurred on a Pacific Northwest dairy farm ("farm A") revealed that the clinical strain was closely related to...

Offshore wind farms constitute a new and fast growing industry all over the world. This study investigates the long term impact on harbour porpoises, Phocoena phocoena, for more than 10 years (2001–12) from the first large scale offshore wind farm in the world, Nysted Offshore Wind Farm, in the Danish western Baltic Sea (72× 2.3 MW turbines). The wind farm was brought into full operation in Dec...

Inflation-adjusted farm prices and farm-wholesale marketing margins for beef and pork have declined over several decades. For example, from 1970 to 1998, real slaughter steer and hog prices declined by 50% and 66%, respectively, while real beef and pork farm-wholesale (FW) marketing margins declined by 57% and 65%, respectively (Figures 1 and 2). These changes have been attributed to declining ...

Family farming, crop science and ‘globalisation’ together largely determine progress against poverty. Faster in 1960-90 than at any time in world history, such progress has slowed down. So have ‘land reform’ and science-based rises in small farmers’ staples food productivity, while aid to agriculture has fallen by over two-thirds and farm prices have been further forced down (and farm science d...

We examine the driving forces behind farmers’ decisions to adapt to climate change, and the impact of adaptation on farmers’ food production. We investigate whether there are differences in the food production functions of farm households that adapted and those that did not adapt. We estimate a simultaneous equations model with endogenous switching to account for the heterogeneity in the decisi...

PURPOSE Although farm operators have frequent exposure to hazardous noise and high rates of noise-induced hearing loss, they have low use of hearing protection devices (HPDs). Women represent about one-third of farm operators, and their numbers are climbing. However, among published studies examining use of HPDs in this worker group, none have examined gender-related differences. The purpose of...

Driven by consumer demands, European legislation has suggested the use of HACCP (Hazard Analysis Critical Control Point) as the quality risk management programme for the whole dairy chain. Until now, an exception has been made for primary producers, but as regulations evolve, on-farm HACCP-like programmes should be ready to assure food safety as well as animal health and animal welfare. In our ...

This paper describes a dynamic model of a wind farm and its nearest utility grid. It is intended to use this model in studies addressing the dynamic interaction between a wind farm and a power system, both during normal operation of the wind farm and during transient grid fault events. The model comprises the substation w here the wind farm is connected, the internal power collection system of ...
