Intensive cultivation and post-harvest vegetable oil production stages are major sources of greenhouse gas (GHG) emissions. Variation between systems reporting disparity have resulted in discordance previous emissions estimates. The aim this study was to assess global systems-wide variation GHG resulting from palm, soybean, rapeseed sunflower production. Such an analysis is critical understand the implications meeting increasing edible demand. To achieve this, we performed a unified...
Abstract Technical efficiency of wheat farms in eastern England is measured through the estimation a stochastic frontier production function using panel data for 1993–1997 crop years. Variations technical index across units are explained number managerial and farm characteristic variables following Battese Coelli (1995) [Empirical Econ. 20, 325–332] incorporating spirit Rougoor et al. (1998) [Agric. 18, 261–272]. The ranges from 62 to 98%. objectives maximising annual profits maintaining...
Participants explored either a real multistory building or to-scale computer simulation of the same building. Following exploration, we assessed their knowledge spatial properties environment. in control group were asked to complete assessment tasks without opportunity explore simulation. Spatial was using four measures: pointing objects not directly visible from test site, Euclidean distance estimates, route and drawings Transfer learning environment evident. Pointing site proved be most...
Meeting EU targets for renewable transport fuels by 2020 will necessitate a large increase in bioenergy feedstocks. Although deployment of first generation biofuels has been the major response to meeting these they are subject wide debate on their sustainability leading development second technologies which use lignocellulosic Second biofuel can be subdivided into those from dedicated crops (DESGB), e.g. miscanthus, or co-products (CPSGB) such as cereal straw. Potential supply straw...
Reducing tillage intensity offers the possibility of moving towards sustainable intensification objectives. Reduced (RT) practices, where plough is not used, can provide a number environmental and financial benefits, particularly for soil erosion control. Based on 2010 harvest year data from nationally stratified Farm Business Survey drawing sub-sample 249 English arable farmers, we estimate that approximately 32% land was established under RT, with 46% farms using some form RT. Farms more...
Technical efficiency in UK maincrop potato production is measured through the estimation of a stochastic frontier function using cross section data for 1992 crop year. Variations technical index across units are explained number managerial and farm characteristic variables following Battese Coelli (1995). The ranges from 33 to 97 per cent. Irrigation storage potatoes after harvest positively correlated with efficiency. Number years experience growing potatoes, small scale farming practice...
A group of 10 severely physically disabled children explored a to-scale computer simulation real multi-storey building. Following exploration, their knowledge the spatial properties environment was assessed by asking them to point fire apparatus that not visible from test site. Subjects in control were asked complete same assessment tasks, but without opportunity explore either building or simulation. The estimates superior indicating good transfer knowledge. Route finding and recognition...
Wheat crops in southeast Queensland (Qld) and northern New South Wales (NSW) were infected with fusarium head blight (FHB)‐like symptoms during the 2010–11 wheat growing season. this region surveyed at soft dough or early maturity stage to determine distribution, severity, aetiology toxigenicity of FHB. FHB was widespread on bread durum, Fusarium graminearum and/or F. pseudograminearum diagnosed from 42 44 sites using species‐specific PCR primers directly spikelets monoconidial cultures...
Evaluation of agricultural intensification requires comprehensive analysis trends in farm performance across physical and socio-economic aspects, which may diverge types. Typical reporting economic indicators at sectorial or the "average farm" level does not represent diversity provides limited insight into sustainability specific pathways. Using business data from a total 7281 survey observations English Welsh dairy farms over 14-year period we calculate time series 16 key (KPIs) pertinent...
Abstract Sustainable intensification is a process by which agricultural productivity enhanced whilst also creating environmental and social benefits. We aimed to identify practices likely deliver sustainable intensification, currently available for UK farms but not yet widely adopted. compiled list of 18 farm management with the greatest potential in , following well‐developed stepwise methodology identifying priority solutions, using group decision‐making technique key experts. The can...
Abstract In Experiment 1, participants explored a desktop computer-simulated three-dimensional environment. Subsequently, they were asked to point objects that not directly visible from the test locality, and draw plan view of 2, following exploration less complex environment, completed their ability find had been encountered during course exploration. neither experiment was there any evidence psychological activity (directing exploration) or physical (interacting with computer) an effect on...
values of the Arrow-Pratt coefficient in range approximately -.0002 to .0012. The recently developed interval approach for elicitation risk preferences was used estimate attitudes Minnesota swine producers. Constant and decreasing absolute aversion were predominant among sample. Seventy-eight percent respondents .0003. A discriminant analysis using producer attributes three estimated intervals concluded that 50 could be classified correct interval.
Abstract Farm level risk analyses have used price and yield variability almost exclusively to represent risk. Results from a survey of 149 agricultural producers in 12 states indicate that consider broader range sources their operations. Significant differences exist among categories with respect the importance crop livestock production. Producers also variety management responses variability. There were significant difference given particular use them. These results implications for...
Abstract Objective Despite widespread concern over exploitation of the European Union's fish stocks, dietary guidelines in UK continue to recommend two portions per week. The present study sought investigate whether health and/or sustainability are motivating factors when purchasing and consuming there sociodemographic trends. Design A structured, self-completion postal questionnaire exploring consumers’ attitudes towards fish, their intake, stated behaviour information. Setting...
SUMMARY The UK dairy sector has undergone considerable structural change in recent years, with a decrease the number of producers accompanied by an increased average herd size and concentrate use milk yields. One key drivers to remaining industry is profitability their herds. current paper adopts holistic approach decomposing variation through analysis net margin data explained physical input–output measures, price variation, labour utilization managerial behaviours characteristics. Data are...
The EU renewable energy directive stipulates a requirement for 10% of transport fuels to be derived from sources by 2020. Second generation biofuels offer potential contribute towards this target with cereal straw representing potentially large feedstock source. From an on-farm survey 240 arable farmers, timeliness crop establishment and benefits nutrient retention incorporation were cited as reasons incorporation. However, two-thirds (one-third) farmers would supply wheat (barley)...
