Última Agriculture, Income Risks and Rural Poverty Dynamics: Strategies of Smallholder Producers in Kenya 31 Kuyiah, Joanne Wasswa; Obare, Gideon A.; Herrero, Mario; Waithaka, Michael M.. Poverty in Kenya has been on the increase over the last decade. It is estimated that 56% of the total population live in absolute poverty. Most of the poor reside in rural areas where agriculture is the main livelihood activity. Majority of Kenya's farmers are smallholders. They account for 75% of the total agricultural output and about 70% of marketed agricultural produce. The fate of smallholder agriculture in this country is therefore central to poverty reduction. A collapse in output and incomes from smallholder agriculture is likely to have damaging welfare effects and retard pro-poor economic growth. Smallholders often operate in a risky environment, which affects the level and variability of household resource endowments and income. The importance...

Ano: 2006 URL: http://purl.umn.edu/25596 Determinants of the Speed of Adoption of Soil Fertility-Enhancing Technologies in Western Kenya 31 Odendo, Martins; Obare, Gideon A.; Salasya, Beatrice. Most adoption studies have employed cross-sectional data in a static discrete choice modelling framework to analyze why some farmers adopt at a certain point in time. The static approach does not consider the dynamic environment in which the adoption decision is made and thus does not incorporate the speed of adoption and the effect of time-dependent elements in explaining adoption. The adoption speed of an innovation is important in various aspects. Based on data from a survey of a random sample of 331 smallholder households in western Kenya, this study investigated determinants of time to adoption of mineral fertilizer, animal manure and compost using Duration analysis. Results revealed that factors that influenced timing of the adoption varied by the...

Ano: 2009 URL: http://purl.umn.edu/50538 The Influence of Social Capital on Natural Resource Management in Marginal Areas of Kenya 31 Mwakubo, Samuel M.; Obare, Gideon A.; Omiti, John M.; Mohammed, Lutta. This paper analyzes the influence of social capital on the farmers' perception of the soil erosion problem and the level of investments in soil conservation in marginal areas of Kenya. It uses data from a survey of 321 households in Machakos and Taita-Taveta Districts. A Heckman's two-step model is applied to assess the influence of social capital on investments in soil conservation by farmers. Results show that the education level of the household head, slope of farmers' fields, proportion of off-farm income, and the status of soil erosion are significant determinants of the likelihood of farmers recognizing soil erosion as an important problem. Household size, slope, land tenure security, membership diversity, age of household head, farm size per capita...

Ano: 2006 URL: http://purl.umn.edu/25502 Leveraging institutions for collective action to improve markets for smallholder producers in less-favored areas 31 Shiferaw, Bekele A.; Obare, Gideon A.; Geoffrey, Muricho; Silim, Said. Using survey data from the community, producer marketing groups (PMGs) and farm households in Kenya, this paper investigates the potential of rural institutions (farmer organizations, their rules and enforcement mechanisms) for remedying pervasive market imperfections and facilitate access to new technology in rural areas. Qualitative and quantitative analyses show that while the functioning of markets is constrained by high transaction costs and coordination failures, PMGs present new opportunities for small producers through vertical and horizontal coordination of production and grain marketing. They pay 20 to 25% higher prices than other buyers and facilitate the adoption of improved varieties that help increase marketable surplus. Their accumulated...

Ano: 2009 URL: http://purl.umn.edu/56941 Economic Efficiency of Smallholder Irish Potato Producers in Kenya: A Case of Nyandarua North District 31 Nyagaka, Daniel; Obare, Gideon A.; Nguyo, Wilson. With declining Irish potato production trends in Kenya this paper identifies and analyses factors that influence the economic efficiency of smallholder Irish potato producers in Kenya by drawing on data from random sample of 130 smallholder farmers from Nyandarua North district. A dual stochastic parametric decomposition technique is used to disaggregate economic efficiency components and a two-limit Tobit model is used to derive efficiency indices as a function of a vector of socio-economic characteristics and institutional factors. Empirical results show decreasing returns to scale in production. The mean economic efficiency is 0.39 with a range of 0.12 - 0.66. Education, access to extension, access to credit and membership in a farmers association...

Empirical Evidence from Baringo District, Kenya 31 Berem, Risper M.; Obare, Gideon A.; Owuor, George. Using survey data from 110 randomly selected honey producers from two divisions in Baringo this paper analyzes the constraints and drivers of value addition in honey, an economic activity with a potential to improve household livelihoods but whose development has remained rudimentary. Baringo District undergoes frequent and prolonged drought that impacts on household livelihood assets. The livelihoods have traditionally been agro-based but due to variations in climatic conditions, crop production has been very low. Livestock production has also been adversely affected by these trends, leaving honey production as a viable alternative for smallholder farmers since it is less dependent on, or affected by climatic variations and is not resource intensive.

Ano: 2010 URL: http://purl.umn.edu/96163 Social Capital and Soil Erosion Control in Agriculturally Marginal Areas of Kenya: The Case of Machakos and Taita-Taveta Districts 31 Obare, Gideon A.; Mwakubo, Samuel M.; Ouma, Emily Awuor; Mohammed, Lutta; Omiti, John M.. This paper evaluates the farmers’ perception of the soil erosion problem, and identifies and analyses social capital elements that motivate households to actively participate in soil conservation in agricultural production process. The data used in the study was generated using a structured questionnaire in a survey that covered 321 households in Kenya’s semi arid districts of Machakos and Taita-Taveta Districts. Two modelling strategies were used: A Probit model was used to estimate the likelihoods of factors that may influence farmers’ perception of soil erosion problem, and a Tobit to estimate parameters of factors that influence terracing intensity. The results indicate that although perception of the soil erosion problem is relatively high in the...

Ano: 2004 URL: http://purl.umn.edu/9532 CATTLE AS ASSETS: ASSESSMENT OF NON-MARKET BENEFITS FROM CATTLE IN SMALLHOLDER KENYAN CROP-LIVESTOCK SYSTEMS 31 Ouma, Emily Awuor; Obare, Gideon A.; Staal, Steven J.. This paper uses data from a survey of two hundred and fifty cattle households in three cattle keeping systems; intensive, semi-intensive and extensive systems to estimate the value of non-market, socio-economic benefits of cattle in Kenya. These benefits of cattle keeping are of special importance in developing countries, where financial markets function poorly and opportunities for risk management through formal insurance generally absent. However, when estimating the total contribution of livestock, these non-market functions are often ignored since they are difficult to value, yet they may contribute to a better understanding of livestock production systems. The use of contingent valuation method is employed in this study to elicit these non-market...

Ano: 2003 URL: http://purl.umn.edu/25895 Rural institutions and producer organizations in imperfect markets: experiences from producer marketing groups in semi-arid eastern Kenya 31 Shiferaw, Bekele A.; Obare, Gideon A.; Muricho, Geoffrey. Many countries in sub-Saharan Africa have liberalized markets to improve efficiency and enhance market linkages for smallholder farmers. The expected positive response by the private sector in areas with limited market infrastructure has however been disappointing. The functioning of markets is constrained by high transaction costs and coordination problems along the production-to-consumption value chain. New kinds of institutional arrangements are needed to reduce these costs and fill the vacuum left when governments withdrew from markets in the era of structural adjustments. One of these institutional innovations has been the strengthening of producer organizations and formation of collective marketing groups as instruments to remedy pervasive market...

Ano: 2006 URL: http://purl.umn.edu/50066 Determining smallholder farmers’ preferences for Push-Pull technology dissemination pathways in western Kenya 31 Murage, Alice W.; Amudavi, David Mulama; Obare, Gideon A.; Chianu, Jonas; Khan, Zeyaur R.. The push-pull technology (PPT) has widely been disseminated to control stemborer (Chilo partellus and Busseola fusca) and Striga weeds (Striga hermonthica and Striga asiatica) in maize fields in Kenya. This study examined farmers’ preferences for various dissemination pathways in order to proffer better targeting of resources in an optimal dissemination strategy. The pathways considered were public meetings (barazas), radio, farmer field schools (FFS), field days (FD), farmer teachers (FT), the fellow farmers (FF) and print materials. Using a weighted score index and ordered probit regression, the different pathways were sequentially ranked as FD, FT, FFS, FF, print materials, Radio, and barazas. Marginal effects from ordered probit showed that farmers had...
