A água no contexto da Zona de Amortecimento Ciências Agrárias
Santos, Henrique Cardoso dos.
The water resources in the Buffer Zone of a Conservation Unit of the Atlantic Rain Forest is important to the quality of life of the community that leaves in the border zone of this unit. The planning of occupation of the Buffer Zone must consider not only all elements of ecological interest of the Conservation Unit, but also it must necessarily focus on measures to preserve and restore the vegetation cover of humid areas for the maintenance of the balance between natural environment sustainability and human use.

: A bioüzemanyagok adózása Magyarországon AgEcon
Palyi, Zoltan.
Megállapítható, hogy a bioetanol adózási helyzete kedvezőbb, mint a biodízelé. Az etanol forgalma dinamikusan növekszik. Magyarországon jelenleg több mint 200 benzinkúton kapható E85 üzemanyag. Annak érdekében, hogy Magyarországon legalább 10% legyen a közlekedési szektorban a „bio” arány, célszerű első lépésként az üzemanyagokban lévő biokomponens-arányt a jelenlegi 4,8%-ról 6,0%-ra, majd 1-2 év múlva 8,0%-ra emelni. A biodízelnél, például a B40- ---------------------------------------------- Apparently the status of bioethanol in terms of taxation is more favourable than that of biodiesel. Ethanol sales are growing dynamically. The E85 fuel is currently sold at more than 200 petrol stations in Hungary. In order to increase the share of “bio” to at...

A business performance index model that measures wealth change in Australian farm businesses AgEcon
Sefton, Clive A.; Cox, Rodney J..
This paper presents an evaluation of a farm-business assessment model that uses financial performance measures and tracks ‘wealth change’ to evaluate performance trends over time, and ranks the relative business performance of commercial participants. Its core component involves the use of comparative analysis, which is structured as an introductory rapid-assessment model, together with a ranking system that has been designed to differentiate the relative performance levels of farm businesses. The system has been labelled as the Business Performance Index (BPI) model to reflect its performance-ranking role that explores the relationships, if any, between farmer attitudes and business performance. The BPI model is discussed within the context of the debate...

A case study of changes in economic performance of an irrigated dairy farm in northern Victoria AgEcon
Ho, Christie K.M.; Malcolm, Bill; Armstrong, Dan P.; Doyle, Peter T..
Average total factor productivity measures for the dairy industry provide an insight into how the industry is performing as a whole, but reveal little about what may be happening on individual farms. A case study of an irrigated dairy farm in northern Victoria, over a 37-year period, found that total milk production and some measures of partial productivity increased substantially. The economic performance of this case study farm over the 37-year period is described and analysed. From records of income and expenses, operating profit, returns to capital, labour and management and total productivity measures were calculated. Between 1980 and 2000, the business achieved productivity gains at higher than the rate estimated for the whole industry. This...

A closer examination of subpopulation analysis of complex–sample survey data AgEcon
West, Brady T.; Berglund, Patricia; Heeringa, Steven G..
In recent years, general-purpose statistical software packages have incorporated new procedures that feature several useful options for design-based analysis of complex-sample survey data. A common and frequently desired technique for analysis of survey data in practice is the restriction of estimation to a subpopulation of interest. These subpopulations are often referred to interchangeably in a variety of fields as subclasses, subgroups, and domains. In this article, we consider two approaches that analysts of complex-sample survey data can follow when analyzing subpopulations; we also consider the implications of each approach for estimation and inference. We then present examples of both approaches, using selected procedures in Stata to analyze data...

A Comparison Of Choice Experiments And Actual Grocery Store Behavior: An Empirical Application To Seafood Products AgEcon
Hudson, Darren; Gallardo, Rosa Karina; Hanson, Terrill R..
In this paper we compare results from an in-store field experiment and a mail survey choice experiment (CE) to investigate CE’s capacity in predicting grocery store market share. For the comparison, we used three seafood products: freshwater prawns, marine shrimp, and lobster. CE estimates were obtained via four econometric models: the conditional logit, the random parameter logit, the heteroskedastic extreme value, and the multinomial probit. We found that the level of control in the grocery store experiment and the choice of econometric model influenced the capacity of CE to predict grocery store market shares.

A comparison of fitness between horses with different exercise history AgEcon
Barker, Anna B.E.; Warren-Smith, A.K..
Anecdotal evidence suggests that a horse’s prior fitness level has an effect on the horse’s ability to return to that previous level of fitness. This trial aimed to test this assumption which would benefit horse trainers to create individual fitness programs for horses. Standardised exercise testing was used to compare the progress of two groups of horses during weeks three and seven of a 14-week training program. Group A had undergone a similar training program twelve months previously and Group B had not. Plasma lactate samples and heart rate monitoring were used to assess the levels of fitness of the horses. Analysis of variance showed that there was no significant difference in post-exercise plasma lactate concentration between the groups. The horses...

A comparison of hypothetical survey rankings with consumer shopping behavior and product knowledge AgEcon
Grebitus, Carola; Colson, Gregory; Menapace, Luisa.
Hypothetical surveys are commonly used to elicit consumer behavior to guide product development, marketing, and labeling strategies. However, despite the prevalence of surveys in consumer food studies, previous work has not assessed the relationship between hypothetical responses and actual consumer behavior in real-world purchase situations.We explore whether attributes cited by consumers in surveys as being important to them when making decisions indeed factor into their product decision process in real-world markets. Evidence from a point of sale study of 702 pork purchasers indicates that there is a strong correspondence between hypothetical survey ratings and actual shopping behavior.

A comparison of the economic and environmental performances of conventional and organic farming: evidence from financial statements AgEcon
Argiles, Josep M.; Brown, Nestor Duch.
While conventional farming systems face serious problems of sustainability, organic agriculture is seen as a more environmentally friendly system since it favours renewable resources, recycles nutrients, uses the environment’s own systems for controlling pests and diseases, sustains ecosystems, protects soils, and reduces pollution. At the same time organic farming promotes animal welfare, the use of natural foodstuffs, product diversity and the avoidance of waste, among other practices. However, the future of organic agriculture will depend on its economic viability and on the determination shown by governments to protect these practices. This paper performs panel regressions with a sample of Catalan farms (Spain) to test the influence of organic farming...

A Comprehensive Evaluation of USDA Cotton Forecasts AgEcon
Isengildina-Massa, Olga; MacDonald, Stephen; Xie, Ran.
This study evaluates all USDA cotton supply and demand estimates for the United States and China (including unpublished price forecasts) from 1985/86 through 2009/10 for accuracy and efficiency. Results reveal that at every stage of the forecasting cycle forecast smoothing was the most widespread and persistent type of inefficiency observed in most U.S. variables. Correlation with past errors indicated the tendency to repeat past errors in most cases. Tendency to overestimate growth was also found. Bias was uncommon and limited to several cases of overestimation of China’s exports and U.S. price and underestimation of China’s domestic use. While forecasts of China’s imports and endings stocks improved, U.S. price and ending stock forecast errors became...
