Análisis de la situación actual de la producción de maíz y de la pluriactividad de los agricultores en el Valle de Puebla. Colegio de Postgraduados
Osorio García, Nemesio.
En México el maíz es el cultivo más importante debido a que es la base de la alimentación de la población y porque actualmente se le considera como materia prima para la industria. Lo anterior hace necesaria una mayor producción de este grano para garantizar la seguridad alimentaria de los mexicanos. Por lo tanto es necesario analizar la situación actual de la producción de maíz a diferentes niveles, incluyendo el regional, para hacer propuestas que nos permitan incrementar la producción de este grano básico. En el Valle de Puebla los rendimientos de maíz son bajos comparados con los resultados experimentales en este cultivo. Los objetivos de esta investigación fueron determinar cuál es la situación actual de la utilización, oferta y demanda de la...

Adapting the social-ecological system framework for urban stormwater management: the case of green infrastructure adoption Ecology and Society
Flynn, Carli D.; Department of Civil and Environmental Engineering, Syracuse University; cflynn@syr.edu; Davidson, Cliff I.; Department of Civil and Environmental Engineering, Syracuse University; Syracuse Center of Excellence in Environmental and Energy Systems; davidson@syr.edu.
Stormwater management has long been a critical societal and environmental challenge for communities. An increasing number of municipalities are turning to novel approaches such as green infrastructure to develop more sustainable stormwater management systems. However, there is a need to better understand the technological decision-making processes that lead to specific outcomes within urban stormwater governance systems. We used the social-ecological system (SES) framework to build a classification system for identifying significant variables that influence urban stormwater governance decisions related to green infrastructure adoption. To adapt the framework, we relied on findings from observations at national stormwater meetings in combination with a...

Intra and Inter organisational determinants of electronic-based traceability adoption: evidences from the French agri-food industry AgEcon
Galliano, Danielle; Orozco, L..
Traceability, the ability to trace the origin of products throughout the supply chain, has become an instrument to assure food quality and safety in agri-food chains. This process is organized within both institutional and market constraints, yet it integrates also a technological sphere marked by the unprecedented development of information and communication technologies. This paper analyses the factors influencing firms’ behaviour, with regards to adopting electronic-based traceability, in the French agri-food industry. These factors (microeconomic determinants) related to firms’ internal characteristics and the factors related to their environment. We use data from the ICT and Electronic Commerce survey from 2002, carried out by the French National...

Technology Adoption and Off-Farm Household Income: The Case of Herbicide-Tolerant Soybeans AgEcon
Fernandez-Cornejo, Jorge; Hendricks, Chad; Mishra, Ashok K..
We model the interaction of off-farm work and adoption of agricultural technologies and the impact of adopting these technologies on farm household income from on farm and off-farm sources after controlling for such interaction, and estimate the model for the case of adoption of herbicide-tolerant (HT) soybeans using a nationwide survey of soybean farms for 2000. We find that adoption of HT soybeans is positively and significantly related to off-farm household income for U.S. soybean farmers, after controlling for other factors. In addition, while on-farm household income is not significantly related to adoption, total household income increases significantly with adoption.

Land Degradation in Ethiopia: What do Stoves Have to Do with it? AgEcon
Gebreegziabher, Zenebe; van Kooten, G. Cornelis; van Soest, Daan P..
Land degradation is a particularly vexing problem in developing countries; as forests are depleted, crop residues and dung are used for fuel, which degrades cropland. In Ethiopia, the government encourages tree planting and adoption of energy efficient stove technologies to mitigate land degradation. We use data from 200 households in Tigrai, Ethiopia to examine the adoption of new stove technologies. Adoption is an economic decision, related to savings in time spent collecting fuel and cooking, and cattle required for everyday purposes. Results indicate adopters of efficient stoves reduce respective wood and dung use by 68 and 316 kg per month.

Socioeconomic Profiles of Early Adopters of Precision Agriculture Technologies AgEcon
Daberkow, Stan G.; McBride, William D..
Corn producers are the largest users of cropland and agrichemicals in U.S. agriculture, and represent a major market for precision agriculture technologies. Based on a USDA survey of 950 corn-producing farms, approximately 9% utilized some aspect of precision agriculture for corn production in 1996. A logit analysis indicated that farmers were more likely to adopt precision technologies if they farmed a large number of corn acres, earned a sizable farm income, and had high expected corn yields. The probability of adoption was also higher for farm operators using a computerized farm record system, who were less than 50 years of age, and who relied on crop consultants for information on precision agriculture.

THE ADOPTION OF IPM TECHNIQUES BY VEGETABLE GROWERS IN FLORIDA, MICHIGAN AND TEXAS AgEcon
Fernandez-Cornejo, Jorge; Beach, E. Douglas; Huang, Wen-Yuan.
Factors influencing the adoption of Integrated Pest Management (IPM) techniques are studied using survey data from individual vegetable producers from Florida, Michigan, and Texas. Farmers who adopt IPM tend to be less risk averse and use more managerial time on farm activities than nonadopters. Adopters are also more likely to operate large, irrigated farms and use more family labor. Locational factors and the type of crop grown are also influential in IPM adoption. The analysis uses a logit framework and introduces adopter categories first conceptualized by rural sociologists.

Beyond semi-dwarf wheat yield increases: impacts on the Australian wheat industry of on-going spillovers from the International Maize and Wheat Improvement Center AgEcon
Brennan, John P..
Wheat genetic materials developed from research at the International Maize and Wheat Improvement Center (CIMMYT) in Mexico for developing countries have provided spillover benefits to Australia. Varieties developed from those genetic materials have resulted in yield increases in Australia. While the initial impact came through the introduction of higher-yielding semi-dwarf wheat crops, those impacts have continued in the post-semidwarf period. CIMMYT’s success in developing countries has also reduced the world price for wheat. While the lower prices affect returns in Australia, the increased yields in Australia from the CIMMYT spillovers from both the semi-dwarfs and the postsemidwarf phases have provided benefits to Australia averaging A $30 million per...

Smallholders' Cost Efficiency in Mozambique: Implications for Improved Maize Seed Adoption AgEcon
Zavale, Helder; Mabaya, Edward T.; Christy, Ralph D..
Maize is an important staple in Mozambique. It is also a dominant crop produced by smallholder farmers. However, the actual maize yields, currently estimated at 1.4 tons/ha, fall short of potential yields of 5-6.5 tons/ha. With population growth rate increasingly exceeding agricultural (and maize) productivity growth rate, the government of Mozambique faces a serious problem of food insecurity and poverty alleviation. This study examines cost inefficiency among smallholder maize farmers in Mozambique, and the impact of improved maize seed adoption on cost efficiency. A Translog functional form is used to estimate the frontier cost function. A cost-inefficiency function is used to examine the factors that determine cost inefficiency among farmers....

Identifying farmer attitudes towards genetically modified (GM) crops in Scotland AgEcon
Hall, Clare.
Consumer attitudes towards genetically modified (GM) food are well documented but there has been much less focus on farmer attitudes to GM technology in agriculture. This paper reports findings from a study investigating farmers’ attitudes to GM crops in Scotland. Results from a Q methodology study reveal three discourses, one apparently pro-GM and demonstrating an expectation of benefits, the second representing a more uncertain position, wary of the potential risks of the technology but likely to be reluctant adopters, and the third describing a group who demonstrate a somewhat fatalistic attitude towards the issue of GM technology adoption and impact. The paper also reports findings from a postal survey conducted as part of the Q methodology study....

Do Large Firms with More Technologies Pay More? AgEcon
Yu, Li; Ji, Yongjie.
Investigation of size wage premium in earning’s literature neglects the important role played by technology adoption. This study models the size selection corrected earning’s function by introducing an extra dimension of selection of technology complexity, using a sample from workers in US hog farms. The estimated wage gap between large and small farms is reduced once correction in selection is controlled. Workers compensate monetary income for better work environment, better health and more job security, in which large farms and technologically advanced farms have advantages.

Rural Competitiveness: Results of the 1996 Rural Manufacturing Survey AgEcon
Gale, H. Frederick, Jr.; McGranahan, David A.; Teixeira, Ruy; Greenberg, Elizabeth.
Establishments in metropolitan and nonmetropolitan locations are surprisingly similar in their adoption of new technologies, worker skill requirements, use of government programs and technical assistance, exports, and sources of financing, according to the results of a nationwide survey of 3,909 manufacturing businesses. The most widespread concern of both metro and nonmetro businesses appears to be with quality of labor. Survey respondents report rapidly increasing skill requirements, and many report problems finding qualified workers. Quality of local labor is the most frequently cited problem associated with nonmetro business locations. Access to credit, transportation, and telecommunications infrastructure is a problem of secondary importance for both...

AN INITIAL INVESTIGATION OF THE POTENTIAL FOR HERMETIC PURDUE IMPROVED CROP STORAGE (PICS) BAGS TO IMPROVE INCOMES FOR MAIZE PRODUCERS IN SUB-SAHARAN AFRICA AgEcon
Jones, Michael; Alexander, Corinne E.; Lowenberg-DeBoer, James.
Pests like the larger grain borer (P. truncatus) and the maize weevil (S. zeamis) cause significant storage losses for African maize producers. The value of storage protection to a market-oriented farmer is a function of price seasonality, value loss prevention, and their opportunity costs of capital. Evidence suggests that hermetic technologies like Purdue Improved Crop Storage (PICS) bags can be effective against these key maize storage pests, but sustainable technology transfer requires that it be profitable for producers. This analysis references dry weight loss figures from key life science articles and builds on previous value loss research to provide a geographic model for potential storage technology adoption. PICS bag profitability with one and...

MANAGING THE CORN ROOTWORM VARIANT: EMPIRICAL RESULTS FROM AN INDIANA FARMER SURVEY AgEcon
Harbor, Anetra L.; Martin, Marshall A..
The emergence of a corn rootworm "variant" has reduced the effectiveness of a corn-soybean rotation in some areas of Indiana. This research identifies potential control alternatives. Empirical results suggest that younger, more educated managers of larger farms would be the most likely to adopt transgenic corn for rootworm control.

Making the market: How U.S. Policy influences near term agriculture and biofuel industry production and profitability under technology adoption AgEcon
Meyer, Seth D.; Binfield, Julian C.R.; Westhoff, Patrick C..
The beneficiaries of technology adoption in agriculture and biofuels markets in the United States are heavily influenced by domestic biofuel policies and market context. Biofuel mandates, one of the key pillars of domestic biofuel policies, may significantly alter the elasticity of demand for biofuels as well as the derived demand for maize used to produce a significant share of ethanol in the United States. Using a stochastic agriculture and biofuels model, we assess how the introduction of technology may affect the crops and biofuel markets under binding and non-binding biofuel mandates and discuss the implications for analysis of EU biofuel policies.

PAYOFFS TO FARM MANAGEMENT: HOW IMPORTANT IS CROP MARKETING? AgEcon
Nivens, Heather D.; Kastens, Terry L.; Dhuyvetter, Kevin C..
In production agriculture, good management is demonstrated by profits that are persistenly greater than those of similar neighboring farms. This research examined the effects of management practices on risk-adjusted profit per acre for Kansas farms over 1990-1999. The management practices were price, cost, yield, planting intensity, and technology adoption (less-tillage). Cost management, planting intensity, and technology adoption had the greatest effect on profit per acre, and cash price management was found to have the smallest impact. If producers wish to have continuously high profits, their efforts are best spent in management practices over which they have the most control.

IMPACTS OF THE ADOPTION OF GENETICALLY ENGINEERED CROPS ON FARM FINANCIAL PERFORMANCE AgEcon
McBride, William D.; El-Osta, Hisham S..
The rapid adoption of genetically engineered (GE) crops by U.S. farmers suggests that these technologies have been perceived to improve farm financial performance. This study develops and applies an econometric model to data from corn and soybean producers in order to evaluate the financial impacts of the adoption of GE crops. Results indicate that the adoption of GE crops has had a limited impact on financial performance that varies by crop, type of technology, type of farm, and region of the nation. Factors other than the financial impacts appear to be important reasons for the rapid adoption of GE crops.
