Última Analysis of Factors Influencing Adoption of Dairy Technologies In Western Kenya AgEcon Makokha, Stella Nabwile; Karugia, Joseph Thuo; Staal, Steven J.; Oluoch-Kosura, Willis. Indicators of poverty in western Kenya show high poverty levels. The area has low dairy development yet the potential for dairy development is quite high. Dairy farming has the potential to reduce poverty by increasing incomes and reducing unemployment. This paper reports factor interrelationships in dairy adoption with a view to understanding factors that influence adoption. The binary probit model was used to analyse data from 1575 households. Contrary to findings from similar studies elsewhere, some factors had a negative association with adoption, thus unfolding a unique adoption process. The association between the factor interactive affects and technology adoption highlighted the importance of exploring factor interrelationships. The widely held...

Ano: 2008 URL: http://purl.umn.edu/52094 Valuation of Cow Attributes by Conjoint Analysis: A Case Study in Western Kenya AgEcon Makokha, Stella Nabwile; Karugia, Joseph Thuo; Staal, Steven J.; Oluoch-Kosura, Willis. The objective of the study was to determine the value that different households attach to attributes of the dairy cow. The cow attributes were, milk yield, disease resistance, feed requirement. The valuation was done in order to quantify the economic trade-offs made during adoption of dairy technologies, assess resource availability, households perceptions on dairy technologies and their farming priorities. This was necessary to understand the adoption patterns of dairy technologies observed and suggest intervention. The Marginal Rate of Substitution (MRS), Marginal Willingness to Pay (mWTP), and Marginal Willingness to Accept (mWTA) that were used were determined from conjoint (CJ) analysis using data from a survey of 630 households in Western Kenya. The... Tipo: Conference Paper or Presentation Palavras-chave: Cow attributes; Conjoint; Marginal willingness to accept; Marginal willingness to pay; Livestock Production/Industries. Ano: 2006 URL: http://purl.umn.edu/25752 Risk Management in Smallholder Cattle Farming: A Hypothetical Insurance Approach in Western Kenya AgEcon Otieno, David Jakinda; Oluoch-Kosura, Willis; Karugia, Joseph Thuo; Drucker, Adam G.; Rege, Edward. Smallholder cattle farming is an important livelihood strategy in most developing countries like Kenya. However, tropical diseases in Africa often wipe out these valuable assets. This paper focuses on mitigation of cattle disease risks through a hypothetical insurance scheme. The study is based on data from a survey conducted on a purposive sample of 300 smallholder cattle farmers in Kakamega and Siaya districts of Western Kenya. Descriptive measures and a regression model were used in the analysis. Results of the study showed that most farmers (91.3%) were willing to participate in the cattle insurance scheme. Also, the farmers observed that the scheme would enable them to increase their herd sizes and change their breed composition. The farmer's mean...

Ano: 2006 URL: http://purl.umn.edu/25489 Valuation of cow attributes by conjoint analysis: A case study of Western Kenya AgEcon Makokha, Stella Nabwile; Karugia, Joseph Thuo; Staal, Steven J.; Oluoch-Kosura, Willis. Better dairy production could reduce poverty and improve nutrition in western Kenya, but the requisite technologies have not been widely adopted. This study collected dairy cow attributes from 630 households to evaluate what factors influence smallholder farmers to adopt technologies. Conjoint analysis was used to compute the marginal rate of substitution between attributes, marginal willingness to pay, and marginal willingness to accept. Two ethnic groups had the highest willingness to pay for cattle with a high milk yield and low feed requirement. The highest marginal rate of substitution for cattle with a high disease resistance and a low feed requirement was from households with off-farm income, from areas with a good agro-climate, and from areas where...

Ano: 2007 URL: http://purl.umn.edu/57012 The impact of non-tariff barriers on maize and beef trade in East Africa AgEcon Karugia, Joseph Thuo; Wanjiku, Julliet; Gbegbelegbe, Sika; Nzuma, Jonathan M.; Massawe, Stella; Macharia, Eric; Freeman, H. Ade; Waithaka, Michael M.; Kaitibie, Simeon; Gulan, Ayele. The East African Customs Union was established in 2005 with the aim of increasing intraregional trade. The Customs Union protocol commits member states to eliminate non-tariff barriers (NTBs) to intraregional trade. However, several NTBs are still applied by member states. This study identifies the existing NTBs on maize and beef trade and quantifies their impact on trade and welfare of EAC citizens using a Spatial Equilibrium Model (SEM). Data on NTBs were collected from traders and transporters of maize and beef cattle in East Africa. Roadblock checks, bribes and custom rules and procedures were identified as the main NTBs to trade. The SEM model shows that a 50% reduction of the cost of NTBs, or their complete elimination would improve social welfare in...

AgEcon Sinja, Judith; Karugia, Joseph Thuo; Baltenweck, Isabelle; Waithaka, Michael M.; Miano, M.D.; Nyikal, Rose Adhiambo; Romney, D.. Technology adoption by farmers is crucial to increasing agricultural productivity hence meeting food and nutrition challenges in Africa. Economists investigating consumer demand have accumulated considerable evidence showing that consumers generally have subjective preferences for product attributes. However, when investigating adoption of new agricultural technologies, economists have lagged behind in analysing how farmers' (the consumer of agricultural technologies) subjective perceptions of technology characteristics affect their adoption decisions. Focusing on farmer perceptions of technologies may provide a better understanding of technology adoption since they deal with the technologies and probably perceive technologies differently from researchers...

The increasing land scarcity and the worsening trend of poverty in Kenya in recent years have raised concerns about the focus on land-based agriculture as the basis of growth in the rural areas. This paper combines two complementary data sets obtained from two locations in Kenya, drawn against distinctively different land availability patterns, to examine the diverse rural asset base and key sources of livelihood in the rural areas. The analysis reveals that while access to productive land is still an important determinant of livelihoods in the rural areas, even where land holdings are very small, growth in farm productivity alone may not guarantee households sufficient incomes to escape poverty. We find evidence to suggest that growth of non-farm sector...

This paper reports on findings of a study to examine the sources used by farmers in search of agricultural information on striga and/or stemborers control technologies and factors that influence acquisition of such information in Western Kenya region. A random sample of 476 households in Suba and Vihiga districts were interviewed and 15 information pathways were identified. Using principle component analysis (PCA) to derive few latent variables that encapsulate maximum variance in the pathways, two components (latent variables) proxying for ‘agricultural knowledge’ were extracted. Type I-knowledge (first component) loaded heavily with sources that had ‘group’ information searching. Type II-knowledge (second component) loaded heavily with sources...
