Banana Value Chains in Central Africa: Constraints and Opportunities

Smallholder farmers in developing countries need to improve their position in food value chains in order to improve their margins and as a strategy for coping with agricultural food price volatility through innovations within the chains. Value chain mappings and gross margin analysis were employed to assess constraints and opportunities for existing value chains for bananas in Central Africa using market survey data. The results showed weak linkages within the banana value chains with poor integration of value chain actors and minimal involvement with regional markets and high-value domestic chains such as supermarkets. Value addition in terms of agroprocessing was carried out at small scale levels using rudimentary techniques limiting the final product to low value markets. Transaction costs comprising transport, handling and storage comprised a high proportion of cost items in the value chain. Generally, the findings suggest that efforts aimed at strengthening linkages within the value chains, collective marketing, penetration into high-value chains and improved processing techniques may provide a potential avenue for enhancing banana value chains in Central Africa.banana value chains, smallholder farmers, Central Africa, collective action, Crop Production/Industries,

Contribution of Economics to Design of Sustainable Cattle Breeding Programs in Eastern Africa: A Choice Experiment Approach

Although livestock forms a very important component of the livelihoods of rural populations of developing countries, productivity remains very low. Livestock keepers are beset by various constraints. In sub-Saharan Africa, cattle are exposed to a number of tropical diseases and other environmental stresses. Breed improvement programs provides key entry points for increasing productivity in cattle populations, especially those plagued by animal diseases. However, breed improvement programs have tended to focus on single, market-driven production traits in isolation of broader livestock system functions. This potentially leads to genotypes that are not well adapted to the environment and not suitable for performing the multiple roles of cattle in developing countries. In order to design a sustainable breed improvement program, farmer preferences for cattle traits need to be integrated into the breeding objective. To explore preferences for cattle traits by cattle keepers, data are used from a choice experiment household survey from a sample of 507 cattle keeping households in trypanosomosis challenge areas in Kenya and Ethiopia. A multinomial logit and mixed logit models are applied to estimate the economic values of preferred cattle traits. The results show existence of preference heterogeneity for cattle traits based on cattle production systems. Further, the results suggest that important traits in developing breed improvement programs should include trypanotolerance, fitness to traction, drought tolerance and fecundity, drawing implications on conservation of breeds which possess these traits.Choice experiment, Cattle production system, Trait preferences, Trypanotolerance, Livestock Production/Industries, D12, D60, C35,

Economic valuation of phenotypic cattle trait preferences in trypanosomosis prevalent production systems of Eastern Africa : implications for sustainable cattle breeding programs

The study examines cattle keeping households’ preferences for phenotypic cattle traits in trypanosomosis prevalent production systems of Kenya and Ethiopia, using cross-sectional choice experiment survey data of 508 households. The data was collected between September 2004 and May 2005. Further, it investigates potentially sustainable pathways by which the households can access improved cattle breeds based on their traits of preferences. Mixed logit model has been employed to investigate existence of preference heterogeneity, while a latent class model is used to investigate the sources of heterogeneity and presence of endogenous preference segmentation for cattle traits amongst the cattle keeping households. The results reveal significant preference heterogeneity among the households based on the cattle production systems. Highly valued traits for the cropping systems include traction fitness and trypanotolerance, while traits associated with herd increase are considered important in pastoral systems. Considering heterogeneity within population segments provides a framework for adapting breeding policy interventions to specific producer segments, by integrating preferred traits in a breed improvement program. Additional results indicate that communal breeding initiatives provide important pathways through which resource-poor cattle keepers can access improved livestock breeds. Factors that influence a household’s willingness to participate in such a collective action decision are analyzed using a binary logit model

Assessment of Farmer Preferences for Cattle Traits in Cattle Production Systems of Kenya

The urgent need to improve livestock productivity in sub-Saharan Africa in order to keep pace with expected increases in demand for meat and milk is very topical. Breed improvement provides key entry points for increasing productivity in cattle populations. However, there are tendencies for breed improvement programs to focus on single, market driven traits such as milk or meat production in isolation of environmental constraints and broader livestock system functions which cattle assume in developing countries. This potentially leads to genotypes that are not well adapted to the environment and not capable of performing the multiple roles that cattle assume in cattle production systems of developing countries. In developing countries, many important functions of livestock are embedded in non-tradable traits that are neither captured in economic analysis nor considered in livestock improvement programs. This study evaluates preferences of cattle keepers in pastoral and crop- livestock systems of selected sites in Kenya for various cattle traits, focusing attention on trypanotolerance and employing choice modelling techniques. These systems are characterized by low input management, harsh environmental conditions and prevalence of various cattle diseases. Trypanosomosis is a serious disease constraint in these systems. The results indicate that farmer preferences for cattle traits are influenced by various factors including cultural practices, production system characteristics and environmental conditions, especially in relation to disease prevalence and availability of cattle feeds.cattle production system, trait preferences, choice experiment, Kenya, Livestock Production/Industries, D11, C35, Q26,

CATTLE AS ASSETS: ASSESSMENT OF NON-MARKET BENEFITS FROM CATTLE IN SMALLHOLDER KENYAN CROP-LIVESTOCK SYSTEMS

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 values. Econometric estimations are then used to assess the factors influencing the non-market benefits function. The results indicate that these benefits are highly valued by cattle keepers and comprise approximately 20% of the animal's total value across the three systems. They are influenced by various production system and household related factors. Implications for policy are drawn.Livestock Production/Industries, QQ112, QQ118, DD223,

Social Capital and Soil Erosion Control in Agriculturally Marginal Areas of Kenya: The Case of Machakos and Taita-Taveta Districts

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 Kenyas 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 study sites, its effect on soil conservation investments is not significant. In Machakos, the significant determinants of terracing intensity include land tenure, crop area, household size, and membership diversity whereas in Taita-Taveta they include age of household head and consumer-worker ratio. Results from the aggregated data show that lagged crop output, group membership density and diversity, cognitive social capital and location significantly influence the terracing intensity on farm household fields. The policy challenge is to establish and strengthen social capital elements that have a strong influence on communities undertaking soil erosion control measures for sustainable agriculture and rural development.Social capital, Marginal areas, Soil erosion, Perception, Two-step estimation, Kenya, Research and Development/Tech Change/Emerging Technologies, C24, D23, Q15, Z13,

Contributions of Social Capital Theory in Predicting Collective Action Behavior among Livestock Keeping Communities in Kenya

Social capital and collective action initiatives provide important avenues for access and uptake of improved livestock technologies through communal breeding programs among resource poor communities in developing countries. This study examines the factors that influence collective action behavior in crop-livestock and pastoralist production systems in Kenya by employing a binary logit model. The results show that age, gender of household members and education level of the household head exert significant influence on the decision to take up collective action. In addition, wealthy households are less likely to participate in collective action initiatives compared to the resource constrained. These results suggest that policies that encourage group formation may be effective in targeting improvement in livelihoods of poor populations through access to improved livestock
