Book Description
We compare productivity and technical efficiency of organic and conventional dairy farms in the United States. We address self-selection into organic farming by using propensity score matching and explicitly test the hypothesis that organic and conventional farms employ a single, homogeneous technology. Utilizing the 2005 Agricultural Resource Management Survey on Dairy Costs and Returns Report (ARMS) data, we reject the homogeneous technology hypothesis and find that the organic dairy technology is approximately 13% less productive. However, we find little difference in technical efficiency between organic and conventional farms when technical efficiency is measured against the appropriate technology.

Book Description
Doctoral Thesis / Dissertation from the year 2018 in the subject Agrarian Studies, Haramaya University, language: English, abstract: White haricot bean is the major source of cash in domestic and international markets and serves as the cheapest source of protein diet for rural households. The double hurdle model and parametric stochastic frontier model of Cobb Douglass type production and cost functions were used to analyze the determinants of adoption and estimate production and cost efficiency scores, respectively. The adoption study revealed that the two decision tiers are independent and the same or different factors affected the two tiers. The decision to adopt is positively and significantly influenced by the frequency of extension contacts, landholding size, agricultural income, perception of the household heads (about price, contribution to soil fertility and nutritional importance), training, and crop diversification; and negatively by distance to market and form of possession of haricot bean plot (tenure). The intensity of adoption is positively affected by non-farm income, contact with NGOs, and negatively with the number of dependents and form of possession of haricot beans plot (tenure). Technical efficiency is significantly and positively influenced by sex (male=1), membership in farmers cooperatives, education of the family, experience in haricot beans farming, use of certified seeds, income from the farm sector and crop diversification; and negatively affected by age of the households. Allocative efficiency differential is significantly and positively influenced by farming experience and household size; and negatively influenced by sex, distance to market and fragmentation of land. Economic efficiency is significantly and positively affected by the education of the family and household size, and negatively by distance to market and fragmentation of land. Provision of improved extension services, enhancing the perceptions on the important attributes of the crop, training, and better access to market are proposed for the first-hand adoption of white haricot beans while works on the creation of alternative sources of income (non-farm activities) contribute more to the intensity of adoption. Supply of certified seeds, education of the households and family members, and access to resources (credit and other inputs, in particular for female-headed households) are proposed to improve the technical efficiency, allocative and economic efficiencies.

Book Description
FAO’s best-selling 2011 publication, Save and Grow, proposed a new paradigm of agriculture, one that is both highly productive and environmentally sustainable. This new book looks at the application of “Save and Grow” practices and technologies to production of the world’s key food security crops – maize, rice and wheat. With examples drawn from developing countries worldwide, it shows how eco-friendly farming systems are helping smallholder producers to boost cereal yields, improve their incomes and livelihoods, conserve natural resources, reduce negative impacts on the environment, and build resilience to climate change. The book will be a valuable reference for policymakers and development practitioners guiding the transition to sustainable food and agriculture.

Book Description
Global demand for food and agricultural products is on the rise. There is hence the need to increase production to meet this growing demand and smallholders will play a significant role. One strategy for smallholders to sustainably increase agricultural production is the use of modern productivity-enhancing technologies such as improved crop varieties. Investments in global agricultural research have resulted in the development and release of thousands of new varieties since the first Green Revolution. However, especially in Sub-Saharan Africa, traditional varieties still dominate smallhold ...

Book Description
Although a large literature highlights the impact of personality traits on key labor market outcomes, evidence of their impact on agricultural production decisions remains limited. Data from 1,200 Ghanaian rice farmers suggest that noncognitive skills (polychronicity, work centrality, and optimism) significantly affect simple adoption decisions, returns from adoption, and technical efficiency in rice production, and that the size of the estimated impacts exceeds that of traditional human capital measures. Greater focus on personality traits relative to cognitive skills may help accelerate innovation diffusion in the short term, and help farmers to respond flexibly to new opportunities and risks in the longer term.

Book Description
This paper studies technology adoption in a duopoly where the unbiased technological change improves production efficiency. Technological progress is exogenous and modeled as a jump process with a drift. There is always a Markov perfect equilibrium in which the firm with more efficient technology never preempts its rival. Also, a class of equilibria may exist that lead to a smaller industry surplus. In these equilibria either of the firms may preempt its rival in a set of technology efficiency values. The first investment does not necessarily happen at the boundary of this set due to the discrete nature of the technology progress. The set shrinks and eventually disappears when the difference between firms' efficiencies increases.

Book Description
Document from the year 2024 in the subject Computer Science - Commercial Information Technology, Nelson Mandela Metropolitan University (School of Information Technology), language: English, abstract: In this book, the author demonstrates how Design Science Research (DSR) approach can be used to design a tailor-made technology adoption assessment framework to gauge small-scale farmers found in developing nations' marginalised rural communities' adoption of ICT. The book presents a practical approach to illustrate the implementation process by using small-scale farmers found in the deeply isolated rural areas of Amathole District Municipality (ADM) of South Africa as a case study. The electronic environment (e-environment) created by the digital age continues to see the adoption of various technologies like Information and Communication Technologies (ICT) by individuals, nations, and organisations to facilitate development, effectiveness, efficiency, enhance productivity and business opportunities. Technology adoption assessment emerged alongside the rapid adoption of technology in the digital age as a tool to evaluate the factors or determinants that influence and contribute to technology adoption. In the case of developing nations rural societies, because of the socio-economic dynamics of the marginalised rural communities, the design of the assessment tools to gauge technology adoption should capture factors such as suitability, relevance of the technology as well as local context and capacity, social implications, and availability of resources to address the unique challenges faced by the region. This makes the design of technology adoption assessment tools to gauge adoption of technology among marginalised communities in developing countries to follow a tailor-made approach.
