A Strategic Approach to the Implementation of Precision Agriculture Principles in Cash Crop Farming AgEcon
Maine, Ntsikane; Nell, Wilhelm T..
Precision agriculture is one of the important agricultural technologies that can assist farmers and managers in promoting long-term success. Precision agriculture can help farm managers increase their management capacity, which is of utmost importance in the highly competitive modern agriculture. Increased yields and/or efficient input use can also be achieved with precision agriculture. Precision agriculture also involve a large capital outlay and requires skills in interpreting the masses of generated data. Modern farmers have to engage in pro-active thinking with regard to suitable agricultural systems that can enhance sustainable success of their farming businesses. Farm managers who are contemplating on getting involved in precision agriculture need...

An Economic Evaluation of Conservation Farming Practices for the Central West of NSW AgEcon
Farrell, Terence C..
Economic benefits that arise from conservation farming practices need to be assessed over several years to account for improvements in soil structure and nutrient levels. A gross margin model was used to assess benefits over the eight-year period 1999-2006 for 12 regions in the central west of NSW. The annual benefits from improved soil structure ranged from $2.46 to $12.82 per hectare (ha). A reduction in tractor power produced annual savings in the range of $0.60 to $4.05 per ha. The cost of soil compaction by livestock grazing on crop areas ranged from $3.41 to $14.90 per ha. The break-even time to pay back costs for the conversion of machinery for no-till seeding was two to three seasons.

ANALYZING FARM PARTICIPATION DECISIONS IN AGROTOURISM ACTIVITIES IN NORWAY: SOME WELFARE IMPLICATIONS AgEcon
Loureiro, Maria L.; Jervell-Moxnes, Anne.
The aim of this paper is to assess the role played by socio-demographic factors, the financial situation of the farm household, as well as the productive orientation and physical location of the farm on the adoption of agro-tourism activities in Norway. Agro-tourism activities in Norway can be classified mainly into two groups: a) renting of fishing and hunting rights, and b) renting of rooms on the farm, huts, cabin, and provision or direct sell of food to travelers. Results indicate that factors such as the size and the location (rural or semi-rural) of the farm play a statistically significant and more important role on the decision of renting fishing and hunting rights than on the development of other agro-tourism activities on the farm. On the...

Braga nasuta (Cymothoidae): an ectoparasite of the Giant Amazonian fish Arapaima gigas (Osteoglossidae) fingerlings cultured in the Amazon region in Northern Brazil Biological Sciences
Jesus, Elson Cardoso de; Cardoso, Lucas; Ferreira, Tamiris Henrique; Martins, Mauricio Laterça; Rodrigues, Marília Danyelle Nunes.
 Isopods Cymothoidae are organisms that parasitize several fish species, both marine and freshwater, provoking important physiological alterations and secondary infections. The genus Braga was proposed to harbor three species of parasitic isopods in freshwater fish from South America: B. brasiliensis, B. cichlae and B. nasuta. Posteriorly, other four species were included: B. patagonica, B. amapaensis, B. fluviatilis and B. bachmanni. Regarding the geographical distribution of the genus, there are registers in Brazil, Argentina, Suriname and Paraguay. In this study, 3,625 fingerlings of pirarucu Arapaima gigas were examined from a commercial fish farm in the Amazon region, Pará State, to observe and identify possible parasites. A total of eleven...

CAP reform and its impact on structural change and productivity growth: A cross country analysis AgEcon
Kazukauskas, Andrius; Newman, Carol F..
The recent reforms of the Common Agricultural Policy (CAP) have exposed the European agricultural sector to a new set of constraints and challenges. The decoupling of direct payments from production is expected to make production decisions more market-oriented as farmers move from mainly subsidy revenue maximization objectives toward profit maximizing behaviour. However, ex-post analyses of the productivity of farms have yet to uncover any evidence of a positive effect of the decoupling policy on farm productivity. Using the Irish, Danish and Dutch farm level data, we identify the extent to which both system and product switching after the introduction of decoupling has occurred and to what extent these changes have contributed to productivity growth in...

Collaboration within the UK Farm Industry AgEcon
Alliston, John C.; Newton, David; Gonzalez-Diaz, Francisco.
This paper addresses the effectiveness of the traditional models of cooperation, and analyses best practices in other commercial sectors in order to identify transferable elements. The Report of the Policy Commission on the Future of Farming and Food (2002) identified a need for farmers to cooperate and collaborate more effectively in their business activities in order to be more competitive. The Plunkett Foundation (1992) suggests that in order to play an important role in the maintenance of the rural economy the Farmer Controlled Business should adopt more imaginative approaches. Using an inductive grounded theory approach and guided interview techniques, experts in the field of business collaboration were selected using a purposive sample approach and...

DOES GUANXI MATTER TO NONFARM EMPLOYMENT? AgEcon
Zhang, Xiaobo; Li, Guo.
Because land is scarce, farmers in China increasingly have to rely on nonfarm activities to enhance their incomes. The functioning of rural nonfarm labor markets is therefore crucial in determining who has access to nonfarm employment. Previous studies have identified human capital as a key factor determining the selection of workers in the rural nonfarm economy. Using a detailed household survey of northern and northeastern China, this paper shows that guanxi (social networks), has also played an important role. With limited nonfarm job opportunities and poor market information, farmers with better social contacts are more likely to obtain nonfarm jobs. Moreover, guanxi has a larger effect on the nonfarm employment opportunities of male workers than...

Early indicators of the extent of climate change on Australian farms AgEcon
Crean, Jason; Parton, Kevin A.; Hayman, Peter; Mullen, John D..
More research is needed before we know the implications of climate change for Australian farms. Nevertheless given the information at hand, an assessment can be made of some early indicators. First, the severity of the recent drought was compared with earlier droughts. Second, the trend in rainfall was examined. Third, projections of climate change were reviewed to assess the likely course of climate variability, and hence provide a picture of the severity of future droughts. Although further research is warranted, the indications are that even if rainfall is no lower in future droughts, they may seem more severe because rising temperatures will tend to increase evaporation and reduce runoff.

Eliciting Risk Preferences: A Field Experiment on a Sample of French Farmers AgEcon
Bougherara, Douadia; Gassmann, Xavier; Piet, Laurent.
We designed a field experiment involving real payments to elicit farmers’ risk preferences. Farmers are a very interesting sample to study since risk has always played an important role in agricultural producers’ decisions. Besides, European farmers may face more risky situations in the future. In this context, it is very important for any economic analysis focusing on agriculture to correctly assess farmers’ behaviour in the face of different sources of risk. We test for two descriptions of farmers’ behaviour: expected utility and cumulative prospect theory. We use two elicitation methods based on the procedures of Holt and Laury (2002) and Tanaka et al. (2010) on a sample of 30 French farmers. The experiment consists in asking subjects to make series of...

Environmental assessment of channel catfish ictalurus punctatus farming in Alabama. Repositório Alice
BOYD, C. E.; QUEIROZ, J. F. de; JEONGYEOL, L.; ROWAN, M.; WHITIS, G. N.; GROSS, A..
An environmental assessment was made of Alabama channel catfish Ictalurus punctatus farming which is concentrated in the west-central region of the state. There are about 10,OOO ha of production ponds with 10.7% of the area for fry and fingerlings and 89.3% for food fish. Food fish production was about 40,800 tons in 1997. Watershed ponds filled by rainfall and runoff make up 76% of total pond area. Water levels in many of these ponds are maintained in dry weather with well water. The other ponds are embankment ponds supplied by well water. Harvest is primarily by seine-through procedures and ponds are not drained frequently. The main points related to Alabama catfish farming and environment issues are as follows: 1) catfish farming in Alabama is...

FARM OPERATIONS FACING DEVELOPMENT: RESULTS FROM THE CENSUS LONGITUDINAL FILE AgEcon
Hoppe, Robert A.; Korb, Penelope J..
This paper examines farms in areas undergoing development, using a longitudinal file constructed by linking several agricultural censuses. Individual farms are followed over the 1982-97 period. Survival, exit, and entrance rates are presented for three types of farms: recreational, adaptive, and traditional. The three types of farms are located where one would expect. Traditional farms are concentrated in nonmetropolitan (nonmetro) counties, while adaptive farms are concentrated in metro core counties. Recreational farms are least common in nonmetro nonadjacent areas, where off-farm opportunities are fewest. The concentration of adaptive farms in metro core counties does not appear to be the result of these farms simply surviving an urban...

Farming and the Internet: Factors Affecting Input Purchases Online and Reasons for Non-Adoption AgEcon
Briggeman, Brian C.; Whitacre, Brian E..
Using the 2005 ARMS data, significant factors are identified that influence the decision to purchase farm inputs over the Internet and reasons for not adopting the Internet. Internet input purchasing farmers tend to be younger and more educated. Non-adopters that are more educated most likely cite Internet security concerns as their primary reason for not adopting.

Farming and the Internet: Reasons for Non-Use AgEcon
Briggeman, Brian C.; Whitacre, Brian E..
Rural broadband infrastructure and service has received a significant amount of funding through the American Recovery and Reinvestment Act of 2009. These funds should increase broadband availability, but will broadband be used in rural areas and in particular by farmers? This paper uses Agricultural Resource Management Survey data to investigate why the majority of U.S. farmers choose not to use the Internet in their farm business. Although frequently cited by policymakers, concerns about inadequate Internet service or security actually account for a small percentage of responses. This research identifies targeted educational programs that focus on alleviating perceived barriers to Internet use.

From Pasture Land to Farm Plots, Triggers and Motivations for Land Use Changes in Afar, Ethiopia AgEcon
Kotu, Bekele Hundie.
Communal land use system has existed in pastoral Afar (as in many other pastoral areas) since time of immemorial accommodating the interests of different user groups. This form of land use system, which has adapted to the harsh environment in which herders raise their livestock, enables efficient utilization of scattered pastoral resources since it accommodates constant mobility of livestock. In contrast to the mobile way of life, which characterizes pastoralism, farming as a sedentary activity is only marginally present in the lowlands of the Afar region. However, the traditional land-use system in Afar is changing nowadays if favor farming because of various reasons. This paper explains such changes mainly based the data collected through a household...

FutureFarm vision AgEcon
Charvat, Karel; Gnip, Pavel; Mayer, Walter H..
This paper defines the first version of a vision of Future Farming project and also a knowledge management system used by European farms which will be designed and developed by the Future Farm project. An important part of the vision is a definition of external drivers and their influence on farm business in future. Paper is looking on a situation in three periods: short (2013), middle (2020) and long-term (2030). Our vision expects that the farming system will continuously converge to the situation of two types of farm: an industrial farm, which will guarantee both the food safety and the food security for European citizens, and multifunctional farms focused on environment protection. The recommendation proposes an architecture based on communication of...
