Última Assessment of developing-country urban consumers’ willingness to pay for quality of leafy vegetables: The case of middle and high income consumers in Nairobi, Kenya AgEcon Ngigi, Marther W.; Okello, Julius Juma; Lagerkvist, Carl Johan; Karanja, Nancy; Mburu, John G.. The improvement in income in developing countries has led to emergence of middle and high income consumers in urban centers. Improvement in income usually causes the shift to consumption of non-staples including leafy vegetables. Thus in major developing country urban centers there has been rapid expansion of the grocery sections featuring leafy vegetables in leading retail stores. Specialty stores have also emerged featuring broad range vegetables. Many middle and high income consumers shop these stores. This study examines the willing of the middle and high income consumers who shop specialized stores to pay for quality of leafy vegetables and drivers of willingness to pay for quality. The study uses contingent valuation and the payment card method in...

Ano: 2010 URL: http://purl.umn.edu/96191 Awareness and use of m-banking services in agriculture: The case of smallholder farmers in Kenya AgEcon Kirui, Oliver K.; Okello, Julius Juma; Nyikal, Rose Adhiambo. Smallholder farmer access to agricultural finance has been a major constraint to agricultural commercialization in developing countries. The ICT revolution in Africa has however brought an opportunity to ease this constraint. The mobile phone-based banking services that started in Kenya urban centers have spread to rural areas and even other countries. Using these services farmers could receive funds invest in agriculture finance transactions. This study examines the awareness and use of m-banking services among rural farmers in Kenya. It also assesses the factors conditioning the use of such services. The study finds high awareness of m-banking services among the smallholder farmers. It also finds that education, distance to a commercial bank, membership...

Ano: 2010 URL: http://purl.umn.edu/96188 Compliance with International Food Safety Standards in Kenya's Green Bean Industry: A Paired Case Study of Small and Large Family Farms AgEcon Okello, Julius Juma; Swinton, Scott M.. This study uses two farm case studies to explore how Kenyan green bean farmers are meeting European food safety standards. For green bean farmers, the standards increase the fixed costs and the transactions costs of producing beans; the standards also alter how bean quality is assessed. Both the small and the large farm use contracts to protect their specific investments in complying with the standards. However, while the large farm invests in improved facilities using its own equity, the small farm uses a marketing group to spread investment costs and reduce the transaction cost to buyers of monitoring the performance of small units. Green bean buyers face the asymmetric information problem of creating incentives for farmers to comply voluntarily with...

Ano: 2005 URL: http://purl.umn.edu/19241 Consumers’ Willingness to Pay for Food Safety in Nairobi: The Case of Fresh Vegetables AgEcon Lagerkvist, Carl Johan; Hess, Sebastian; Ngigi, Marther W.; Okello, Julius Juma. Large urban areas in developing countries represent currently the most dynamically growing markets for food products. This study investigates the willingness to pay of consumers in Nairobi for safer leafy vegetables. We survey individuals’ perceived food safety across four major market categories, while also considering the explanatory role of trust and behavioral, psychological, and socio-demographic covariates. Results show that willingness to pay is market-specific and multi-faceted, with trust and perceived risks as important drivers, while income plays only a subordinate role. We conclude that policy makers should aim to reduce asymmetric information within the value chain without raising food prices such that safer vegetables would become...

Ano: 2006 URL: http://purl.umn.edu/8546 Does the environment in which ICT-based market information services (MIS) projects operate affect their performance? Experiences from Kenya AgEcon Okello, Julius Juma; Ndirangu, Lydia K.. The need to provide agricultural information to farmers has led to emergence of numerous ICTbased MIS projects in developing country. These projects aim at promoting commercialization of smallholder agriculture and subsequently their welfare. This study examines the how the environment in which such ICT-based MIS affect their performance. It specifically uses the DrumNet project, an ICT-based MIS, to assess how the socio-economic, physical, political and physical environment in the project areas affected its performance. The study finds that those transaction-related problems, especially strategic default, deriving from these environmental factors greatly undermined the performance of DrumNet forcing it to relocate severally. It discusses policy... Tipo: Journal Article Palavras-chave: ICT-based MIS projects; The DrumNet model; Operational environment; Performance; Kenya; Research Methods/ Statistical Methods. Ano: 2010 URL: http://purl.umn.edu/96193 Does use of ICT-based market information services (MIS) improve welfare of smallholder farm households: Evidence from Kenya AgEcon Okello, Julius Juma. The need to provide agricultural information to farmers has led to emergence of numerous ICT-based MIS projects in developing country. These projects aim at promoting commercialization of smallholder agriculture and subsequently their welfare. This study examines the welfare effects of one such project in western Kenya. It uses household food security and access to medical health services as proxies of welfare. The study finds that farmers that use ICT-based market information are more food secure and have better access to medical health services than their counterpart. It highlights policy implications of these findings.

Development literature has recently promoted the use of producer organization in linking farmers to better-paying commodity markets. However, empirical studies find mixed performance of such organizations. This study examines the producer organization’s internal factors that may explain the differences in the performance of producer organizations. It specifically analyzes the role of social capital in a producer organization on the performance of such organization using quantitative techniques. As hypothesized, this study finds that social capital positively affects the performance of producer organizations. The implication of these findings is that development strategies that target commercialization of smallholder agriculture through producer...

Ano: 2009 URL: http://purl.umn.edu/51466 Food Safety Requirements in African Green Bean Exports and Their Impact on Small Farmers AgEcon Okello, Julius Juma; Narrod, Clare A.; Roy, Devesh. Many African countries have moved into the production of non-traditional agricultural products, in an effort to diversify their exports and increase foreign currency earnings. However, in order to access developed country markets and urban domestic markets, these products must meet food safety requirements, including protocols relating to pesticide residues, field and pack house operations, and traceability. Faced with stringent food safety requirements, companies that establish production centers in low-income countries might exclude poor farmers, thus negatively impacting the poor. We herein study this issue in the case of the green bean export sectors in three African countries: Ethiopia, Kenya and Zambia. In the short-term, stringent food safety...

Ano: 2006 URL: http://purl.umn.edu/20430 Institutional Innovations for Smallholder Compliance with International Food Safety Standards: Experiences from Kenya, Ethiopian and Zambian Green Bean Growers AgEcon Okello, Julius Juma; Narrod, Clare A.; Roy, Devesh. Many African countries have moved into the production of non-traditional agricultural products to diversify their exports and increase foreign currency earnings. Accessing developed country markets requires meeting food safety standards brought about by several demand and supply side factors. Food retailers in the EU, the major destination market, have developed protocols relating to pesticide residue limits, field and packinghouse hygiene, and traceability. In this changing scenario where food safety requirements are getting increasingly stringent, there are worries that companies that establish production centers in LDCs might exclude smallholder farmers. In this paper, we study the cases of green beans production in Ethiopia, Kenya and Zambia for export...

Ano: 2008 URL: http://purl.umn.edu/52183 Prevalence and drivers of seed and pollen-mediated geneflow in sorghum: implications for biosafety regulations and policy in Kenya AgEcon Mgonja, Mary A.; Okello, Julius Juma; Mwangi, Stephen G.; Manyasa, Eric; Ouma, James Okuro; Godiah, Lawrence; Alumira, Jane; Kibuka, J.. This paper uses a random sample of 881 farmers drawn from eastern and western Kenya to examine the prevalence and drivers of seed and pollen mediated geneflow in the two major sorghum growing regions. It employs both qualitative and quantitative techniques to assess farmers’ awareness of wild sorghum varieties, the practices they use in maintaining varietal purity and the conditioners of their success in maintaining the purity of cultivated varieties. The study finds that, among others, cultural differences, agro-climate and poverty affect the awareness, practices used in maintaining varietal purity and farmers’ success in doing so. These findings have implication for biosafety and policy in Kenya due to the clamour to introduce genetically modified...

Ano: 2009 URL: http://purl.umn.edu/51901 The Effect of Developed-Country Pesticide Standards on Health and Pesticide-Induced Morbidity of Kenya's Green Bean Family Farmers AgEcon Okello, Julius Juma; Swinton, Scott M.. This paper examines the effects of compliance with developed country pesticide standards (DC-PS) on pesticide-related health costs and morbidity of developing country fresh vegetable growers. DC-PS require that farmers i) only use approved pesticides (usually less toxic to humans than ones used before), ii) apply pesticides only when pest scouting reveals the need to do so, and iii) handle, use, store and dispose off pesticides in ways that do not pose health threats to farm workers and farm family members. This paper uses survey regression to estimate a model of health costs of pesticide exposure (based on cost of illness approach) and survey poisson regression to estimate a model for use of protective devices. It finds that compliance with DC-PS reduces... Tipo: Conference Paper or Presentation Palavras-chave: Agricultural and Food Policy. Ano: 2006 URL: http://purl.umn.edu/25508 The Prevalence of Under-Nourished Child Obese Mother Phenomenon in Rural Areas: Evidence from Central Province of Kenya AgEcon Mburu, John G.; Okello, Julius Juma. Attainment of nutritional security is a major focus of the Millennium Development Goals. Despite efforts, Sub-Saharan Africa countries are yet to make significant progress in becoming nutritionally secure. Over the years, maternal obesity and child under-nutrition have concurrently been on the increase. The rise in obesity and child under-nutrition is attributed to, among others, urbanization-driven shifts in eating habits and lifestyle, changes in purchasing power, food assistance and stress-related medical conditions. Studies in Asia and Latin America have associated co-existence of adult obesity and child under-nutrition with urban areas. In this paper we examine the prevalence of child under-nutrition and mother obesity in rural Kenya. We find that 22...

Ano: 2008 URL: http://purl.umn.edu/52160 The Role of ICT-based Market Information Services in Spatial Food Market Integration: The Case of Malawi Agricultural Commodity Exchange AgEcon Katengeza, Samson P.; Mangisoni, Julius H.; Okello, Julius Juma. The government of Malawi in 2004 initiated an ICT-based Malawi Agricultural Commodity Exchange (MACE), a market information service project, to improve access by farmers to market information. MACE was intended to improve the efficiency of agricultural markets as part of the strategy to improve food security. This study uses quantitative methods to examine whether MACE has contributed to efficiency of rice markets in Malawi. It especially tests if MACE has contributed to spatial integration of rice markets. As hypothesized, the study finds that the tendency of rice prices to move together in spatially separated markets has significantly increased since the implementation of MACE. It concludes that ICT-based market information services improve the...

Ano: 2007 URL: http://purl.umn.edu/50001 The Role of Varietal Attributes on Adoption of Improved Seed Varieties. The Case of Sorghum in Kenya AgEcon Timu, Anne G.; Mulwa, Richard M.; Okello, Julius Juma; Kamau, Mercy W.. This paper examines the effect of variety attributes on adoption of improved sorghum varieties in Kenya. Using data from 140 farmers, the paper uses a multivariate probit to identify variety-specific drivers of adoption. The results on the perception of farmers variety attributes show that improved varieties had desirable production and marketing attributes while the local varieties were perceived to have the best consumption attributes. Evidence further indicates that the major sorghum variety attributes driving rapid adoption are taste, drought tolerance, yield, ease of cooking and the variety’s ability to fetch a price premium. Early maturity, a major focus of research has no effect on adoption. The findings of the study imply that, while developing...

This paper examines the high value chains (HVC) for green bean exports from Africa to identify the critical points at which exporters exercise great caution in preventing produce contamination with pathogens and pesticide residues. It then examines the control points that pose greatest threat to continued participation of smallholder farmers in the HVC and discusses the strategies African countries have used to maintain smallholder farmers in the green bean HVC. The paper identifies six critical control points. Among these, smallholders are most threatened with exclusion from HVC at two control points. At those points the farmer must make costly lumpy investments to meet the standards. To overcome the likelihood of smallholders being excluded from HVC at...
