ABSTRACT Many rural households rely on indigenous fruit trees as sources of cash and subsistence in the Southern Africa Development Community (SADC), but until recently there has been little effort to cultivate, improve or add value to these fruits. Since 1989 the International Centre for Research in Agroforestry (ICRAF: now the World Agroforestry Centre) initiated research-and-development work on more than 20 priority indigenous fruit trees in five SADC countries aimed at improving income in rural communities. A participatory approach was used in all stages of their domestication, product development and commercialization. Country-specific priority species were identified in five countries based on discussions with a wide range of users. These species have now become the focus of a regional tree domestication programme. An impact analysis indicates that a robust domestication programme will create incentives for farmer-led investment in the cultivation of indigenous fruit trees, as an alternative to wild fruit collection, especially where there is a decrease in fruit abundance. In Zimbabwe, the returns to family labour of collecting wild fruits are two to three times greater than other farming activities. These returns will be further increased by domestication. Progress in the domestication of four priority fruit tree species Uapaca kirkiana, Strychnos cocculoides, Parinari curatellifolia and Sclerocarya birrea from the miombo woodlands in southern Africa is reviewed. Preliminary results indicate that the long juvenile phase of Uapaca kirkiana can be shortened from 12–16 years to less than four years, using vegetative propagation methods. On-going multidisciplinary tree crop domestication research includes molecular genetic analyses, tissue culture, post-harvest storage, production economics, nutritional analyses, market and supply chain surveys, processing and feasibility assessments of pilot enterprises. Holistic plans are needed to promote cultivation and ensure product quality on farms and to maximize competitiveness at the farm gate and throughout the supply chain.

Purpose – In recent years, governments, donors, and NGOs have increasingly embraced value chain development (VCD) for stimulating economic growth and combating rural poverty. In line with the rise in interest, there has been a proliferation of guides for VCD. The purpose of this paper is to present the results of a review of 11 guides for value chain along six different dimensions, ranging from objectives and value chain definitions to monitoring impact. The paper concludes with suggestions for the use of guides based on local needs and context, and recommendations for future guide development. Design/methodology/approach – The review compares the concepts and methods endorsed and it assesses the strengths and limitations of the guides for steering development practice. Findings – Overall, the guides provide a useful framework for understanding markets and engaging with chain stakeholders, with a strong emphasis on strengthening institutions and achieving sustainability of interventions. However, the guides often lack discussions on the conditions necessary at different levels for VCD to advance development objectives and achieve that sustainability. The guides are designed to be implemented largely independently of the specific context, in which the chain is situated, despite the major implications context has for the design of interventions and overall success of the chain. Attention to mutual learning, whether related to tool design or the outcomes and impacts of VCD interventions, is limited. Research limitations/implications – More critical reflection and debate is needed on the design of guides for VCD. The authors suggest three areas for this reflection and debate: concepts, methods, and tools for addressing the needs of the poor in value chains; tools for addressing variations in the context; and mechanisms for mutual learning on the design and implementation of VCD. Originality/value – The paper concludes with various recommendations for guide authors and donors that support VCD.

The cultivation of indigenous and exotic fruits for sub-Saharan Africa's domestic markets can bring increased revenues for smallholders and improve the diets of local consumers. There are, however, many bottlenecks which need to be addressed so that wider benefits from such activities are realised. Here, we describe key interventions being taken to address current constraints. For indigenous fruit trees, it is necessary to set priorities for which species to promote and to engage in participatory domestication for the improvement of yield, quality and germplasm delivery to farmers. For exotic fruits, 'south-south' transfer of advanced cultivars and the development of small-scale commercial suppliers of planting material are required to reinvigorate production. For both indigenous and exotic species, a focus on improving market value chains to bring greater benefits to producers is needed. We describe where further work is required to increase efficiency in the sector and to favour smallholder involvement.

European Union retailers are setting global benchmarks for the production of fresh food and are asking their suppliers for produce to be certified according to food safety and quality standards. Compliance with these standards for developing countries' small-scale producers entails costly investment in variable inputs and long- term structures. Limited empirical evidence exists either to refute or confirm the concern that the proliferation and enhanced stringency of these standards marginalize smallholders from the global market. This paper therefore explores the costs of compliance, factors explaining the smallholder decision to adopt EU private quality standards, and the impacts of the standards on farm financial performance. We develop a 2-stage standard treatment effect model to account for self-selection as a source of endogeneity. Analysis is based on a random cross section sample of 439 small-scale export vegetable producers in Kenya whose production was monitored in 2005–2006. We demonstrate that adopters and nonadopters are distinguishable by their asset holding and household wealth, access to services, labor endowment, and level of education. Once we control for the endogeneity problem, we find that small-scale producers can benefit substantially from adopting the standards at the farm level.

Abstract This article evaluates the impact of adoption of European Union (EU) private‐sector standards on farmers' health in rural Kenya. The study utilizes cross‐sectional farm household‐level data collected in 2006 from a randomly selected sample of 439 small‐scale export farmers. We estimate the casual impact by utilizing a two‐stage Poisson regression model, two‐stage standard treatment effect model, as well as by regression based on propensity score, to assess the robustness of the results. Using these techniques, we demonstrate that the pesticide‐ascribed incidence of acute illness symptoms and the associated cost of illness significantly decrease with the adoption of standards. Ceteris paribus , farmers who adopt standards experience 70% lesser incidence of acute illness and spent about 50–60% less on restoring their health than nonadopters. Although standards can potentially prevent resource‐poor smallholders from maintaining their position in lucrative export markets, they can also result in positive changes in the health of those farmers who do adopt them, as shown by these results. This implies that, if adopted on a large scale, standards may reduce production externalities, corroborating the view that they may serve as a catalyst to transform production systems in developing countries.

Abstract This article provides an empirical analysis of the impact of European Union (EU) private food safety standards on pesticide use and farm‐level productivity among small‐scale vegetable producers in Kenya. We apply an extended three‐stage damage control production framework, accounting for multiple endogeneity problems, to farm‐level data collected from a random cross‐sectional sample of 539 small‐scale producers. Estimation results show that farmers producing vegetables for the domestic market use significantly lower quantities of pesticides than do export farmers. However, contrary to findings elsewhere, the econometric evidence here shows that both domestic and export‐oriented vegetable farmers in Kenya use pesticides at levels below the economic optimum. The results also show that the adoption of standards by export farmers does not have any significant impact on total pesticide use. However, adopter categories are distinguishable in terms of types of pesticide used, i.e. adopters use safer pesticides based on World Health Organization (WHO) classification. The third‐stage structural revenue model results demonstrate that adoption of standards has a positive and significant impact on revenue raised in vegetable production. Nevertheless, farmers producing for the export market are indistinguishable from those producing for the domestic farmers in terms of the total revenue earned from producing vegetables during the rainy season, on a ‘per acre’ basis. Although standards can potentially prevent resource‐poor smallholders from maintaining their position in the lucrative export markets, they can also result in positive changes in the production systems of those small‐scale farmers who adopt it, as shown by these results.

‘Sustainable cocoa’ has attracted considerable attention. However, stakeholders in cocoa development may differ in their understanding of sustainable cocoa, their interests and actions taken in advancing sustainable cocoa. This article analyses cocoa sustainability at nested scales and analyses to what extent sustainability standards, policies and development projects address sustainability concerns and contribute to ecosystem services. The analysis is based on literature reviews and key informant interviews in Sulawesi (Indonesia), Ucayali (Peru) and Centre Region (Cameroon). Producers in all three countries shared concerns of price volatility, weak farmer organizations and dependence on few buyers. Producers in Sulawesi and Centre Region compensated low returns to cocoa production by diversification of cocoa systems. Public and private development actors were concerned with low production volumes. Research has so far focused on biodiversity loss, which differed depending on the cocoa sector’s age in a country. Policies and development programs in all countries have focused on cocoa sector expansion and productivity increases, irrespective of smallholder needs for economically viable farming systems and existing market structures resulting in little bargaining power to farmers. Sustainability standards have spread unevenly and have converged in compliance criteria over time, although initially differing in focus. Recently added business and development criteria of sustainability standards can potentially address farmers’ concerns. Competing interests and interdependencies between different actors’ responses to concerns have so far not been openly acknowledged by public and private sector actors.

Vegetable export production is a major source of income and contributes to the alleviation of poverty in Kenya. However, emerging production standards pose a challenge to continued smallholder involvement. This paper assesses the number of smallholders in export vegetable production in Kenya, their link to the export market and their EurepGAP certification status. In the latter half of 2005, about 11,100 smallholders produced export vegetables in nine districts of Kenya involving about 350 certified smallholders. French beans were the major crop; more smallholders were linked to the export market by middlemen and flexible arrangements than by an export company. In addition to other factors, the export sector can serve as a role model for the domestic sector with respect to production standards.

Certification of adherence to social and environmental standards allows companies involved in the (global) trade of commodities to dissociate themselves from negative impacts in the public eye. It can go beyond compliance with legal requirements. Certification can be an attempt to shift blame to uncertified others, but it can also contribute to resolving the underlying issues of concern. We provide a framework for a study of when, where and how certification schemes emerge and evolve, with specific attention to the degree to which underlying issues get addressed. Three strands of literature are combined in this framework (1) the issue–attention cycle as a schematic representation of public concerns shaping policy responses; (2) the management swing potential defined as the gap between best and worst current production systems and the basis for defining standards and (3) global value chains that link distant producers and consumers, and the power relations along these chains, including standards and certification. Based on literature review, we introduce a set of four propositions that inform testable specific hypotheses. We outline questions for reviews, in subsequent papers of this issue, of the experience on timber, oil palm, coffee, cacao and rubber as tropical-forest-margin commodities dominated by global trade.EDITED BY Christian Albert

The East Usambaras in Tanzania are a tropical biodiversity hotspot where current agricultural management practices pose threats to forest conservation and development objectives. Promoting sustainable agricultural intensification (SAI) would improve long-term productivity and reduce pressure on forest reserves. The study objective was to identify household-level characteristics that influence adoption of improved management practices, specifically soil replenishment practices, in order to identify opportunities and constraints to scaling up SAI to landscape level. First, three common farming systems and a fourth agroforestry (AF) model were developed to estimate the relative profitability of incorporating fallow, manure, and non-timber forest product activities. Next, household surveys were conducted and a logistic regression analysis was used to measure the influence of socioeconomic characteristics, physical and financial assets, tenure security, and plot-specific attributes on adoption of soil replenishment practices that were specified in the model. Findings showed that the AF model was financially competitive but raises opportunity costs to labour when compared to common systems. Marital status, household size, remittances, credit access, and tenure security significantly influenced adoption of fallow and applying organic inputs. Significant plot-specific attributes included perceived fertility and distance from the homestead. Policies to scale up SAI should consider these factors and emphasize improving markets for AF species and extension services.

Vulnerability to poverty is a major problem in the rural areas of Sub Saharan Africa. Rural Households are confronted with various covariate and idiosyncratic shocks and are often severely constrained in coping with such events. They frequently resort to food from natural resources such as indigenous fruits during times of crisis. The availability of such food sources is increasingly at risk due to deforestation and biodiversity loss. The objective of this paper is to quantify the contribution of indigenous fruit trees towards reducing vulnerability to food insecurity and poverty. The methodology used is a multi-period stochastic household income model. The data were collected in a case study in Zimbabwe using detailed monthly income and expenditure records of a sample of 39 rural households in two areas. The two regions differ in their agricultural system. In one area horticulture, off-farm activities and exotic fruits are a major source of income while in the other area indigenous fruits are a more important source of income. This paper concentrates on the latter area. Model calculations show that rural households in Zimbabwe are highly vulnerable to seasonal fluctuations in income and therefore a critical period where households run high risk of being food insecure can be identified. While indigenous fruits, as a low cost 1 International Centre of Insect Physiology and Ecology (ICIPE), Nairobi, Kenya, dmithoefer@icipe.org (for merly 2 & 3). 2 Development and Agricultural Economics, Faculty of Econo mics and Business Administration, Hannover University, Germany. 3 World Agrofore stry Centre (ICRAF), Lilongwe, Malawi. natural resource, can facilitate income-smoothing, the role of other sources of income must not be neglected. The paper concludes that diversified season-specific income generating portfolios must be designed of which indigenous fruit trees have a role to play.

Abstract Lepidopteran stem borers are the key pests of maize in Sub-Saharan Africa. In the lowland tropics, dry mid-altitude, dry transitional and the moist mid-altitude zones of Kenya, the invasive crambid Chilo partellus (Swinhoe) (Lepidoptera: Crambidae) causes up to 73% yield loss. The International Centre of Insect Physiology and Ecology (ICIPE) started a biological control (BC) program in 1991 to control stem borers in subsistence agriculture in Africa with emphasis on classical BC of C. partellus. The project released the braconid larval parasitoid Cotesia flavipes Cameron (Hymenoptera: Braconidae) in 1993 in coastal Kenya, where it got established and spread to other regions. This study assesses the economic impact of the introduced parasitoid. Temporal data on percentage parasitism by the introduced parasitoid and on stem borer density were collected between 1995 and 2004. Socio-economic data was collected through administration of questionnaires to 300 farmers. Economic impact of the project was calculated as the value of the yield loss abated by the parasitoid based on a model of expected stem borer density and parasitism level. Average annual parasitism increased linearly from the time of introduction to reach 20% parasitism by 2004. The net reduction in total stem borer density over the last 10 years was 33.7%, thus abating 47.3% of yield loss. The region will accumulate a net present value of US $ 183 million in economic benefits in 20 years since release of the parasitoid. Introduction of other parasitoid species targeting the egg and pupal stages of the stem borer life cycle stages would be required for biological control to push yield loss by stem borers to an insignificant level. Résumé Contrôle biologique des foreurs des céréales au Kenya : une approche économique Les lépidoptères foreurs de graminées sont des ravageurs importants du maïs en Afrique subsaharienne. Dans les zones de faibles et moyennes altitudes du Kenya, le foreur exotique Chilo partellus (Swinhoe) (Lepidoptera : Crambidae) a causé jusqu'à 73% de perte de rendement. Le Centre international pour l'étude de la physiologie et de l'écologie des insectes (ICIPE, son abréviation anglo-saxonne) a initié en 1991 un programme de lutte biologique classique pour lutter contre ce ravageur. Ce programme a permis la libération en 1993 d'un parasitoïde braconide, Cotesia flavipes Cameron (Hymenoptera : Braconidae), dans la région côtière du Kenya, où il s'est établi et à partir de laquelle il a colonisé d'autres régions. Cette étude détermine l'impact économique de l'introduction de ce parasitoïde. Des données temporelles sur le pourcentage de parasitisme et sur la densité de foreurs ont été collectées entre 1995 et 2004. Les données socio-économiques ont été obtenues à l'aide d'un questionnaire diffusé auprès de 300 fermiers. L'impact économique a été calculé à partir des données de perte de rendement inférées par un modèle d'estimation de la densité de foreurs et du taux de parasitisme. Le niveau moyen de parasitisme a augmenté linéairement au cours du temps depuis l'introduction du parasitoïde pour atteindre 20% de parasitisme en 2004. La réduction nette de la densité totale de foreurs a été de 33,7% lors de cette dernière décennie, réduisant de 47,3% la perte de rendement. La région devrait accumuler un bénéfice net économique de 183 millions de dollars américains dans ces 20 dernières années depuis que le parasitoïde a été lâché. L'introduction d'autres espèces de parasitoïdes actives contre les oeufs et chrysalides des foreurs devrait permettre de renforcer le contrôle biologique afin de rendre les pertes de rendement causées par les foreurs insignifiantes.

This paper defines three types of typical certified farms in Kenyan export production: smallholder farms, large-scale contracted farms, and exporter-owned farms. It assesses their economic performance, compares the financial cost of compliance with the EurepGAP standard, and analyses transaction costs. Results show that larger farms are not generally performing more efficiently compared to smallholders who implemented the EurepGAP standard. Despite higher monitoring costs as a result of the introduction of standards, smallholder vegetable producers remain an important source for the exporter companies.

Horticulture is a key sector of the Kenyan economy. It improves household welfare through providing income, satisfying domestic food needs and improving human nutrition. Next to market access pests and diseases are the major constraints. With the adoption of Farmer Field Schools (FFS) and Common Interest Groups (CIG) as information sources in horticultural production, it is not yet understood how effective the two approaches en- \nhance environmentally and health friendly production practices such as integrated pest management (IPM). It is expected that IPM information is to a greater extent communicated among farmers belonging to farmer groups because of the enhanced interaction among group members. This paper presents findings of farmer preferences in the choice of information sources and assesses factors that influence IPM information reception and \nsharing. The analysis applies a bivariate probit regression model for reception and sharing of IPM information to survey data from a random sample of 487 smallholder horticultural producers who are either FFS members, CIG members or non-group based farmers. IPM information and knowledge in this paper is defined as a range of practices including scouting, sanitation, crop rotation, mixed cropping, hand picking, solarisation, planting resistant varieties, applying plant extracts and selective pesticide application. Findings show \nthat government extension staff, NGOs, friends, and neighbours are the three most important information sources for horticulture production and IPM. FFS farmers have more knowledge on IPM practices than CIG and non-group based farmers. Regression results show that membership in farmer groups, gender, education, locality, household size, landper capita, distance to extension service, frequency of listening to radio and literate hou- \nsehold members significantly influence information flow. FFS farmers are more likely to receive IPM information than individual farmers whereas CIG farmers are not distinguishable from individual farmers with respect to receiving IPM information. Unlike FFS and non group based framers, CIG farmers are more likely to share IPM information. Implications may be that the intensive training of FFS farmers promotes information reception and knowledge accumulation but promotes close knit interaction in the group which prevents \ninformation leaving the group. This is being further tested.

Coffee is generally grown in areas derived from forest, and both its expansion and management cause biodiversity loss. Sustainability standards in coffee are well established but have been criticized while social and environmental impact is elusive. This paper assesses the issue-attention cycle of coffee production in India and Nicaragua, including producer concerns and responses over time to concerns (sustainability standards, public regulations and development projects). Systematic comparison of the socioeconomic, environmental and policy context in both countries is then used to explore potential effects of sustainability standards. Results show limits, in local context, to relevance of global certification approaches: in both countries due to naturally high levels of biodiversity within coffee production systems global standards are easily met. They do not provide recognition for the swing potential (difference between best and worst) and do not raise the bar of environmental outcomes though nationally biodiversity declines. Nicaraguan regulations have focused on the socioeconomic development of the coffee sector via strengthening producer organizations, while India prioritized environmental and biodiversity conservation. In India, externally driven sustainability standards partially replace the existing producer–buyer relationship while in Nicaragua standards are desired by producer organizations. The temporal comparison shows that recently local stakeholders harness improvements through their unique local value propositions: the ‘small producer’ symbol in Nicaragua and certification of geographic origin in India. Nicaragua builds on the strength of its smallholder sector while India builds on its strength of being home to a global biodiversity hotspot.EDITED BY Beria Leimona

As the export of fresh fruits and vegetables from Kenya targets almost exclusively the European market stricter regulations, e.g. export standards introduced by the food industry, like EurepGAP, present a challenge for Kenyan horticulture. These standards have become more important in Europe and influence producer decisions in a developing country like Kenya. To address these issues a study has been conducted that investigates investments necessary for meeting the standard and the process of compliance of small to large-scale Kenyan vegetable export farmers. The objectives of this paper are: (1) to compare the economic performance of different types of certified farms and (2) to assess the costs of compliance with the EurepGAP standard. The study applies the concept of typical farm models to examine the impact of EurepGAP standard on three types of EurepGAP certified farms. The first model refers to small-scale farms, which are normally organised in groups. The second model describes the large-scale farms contracted by an exporter company, which mainly produce for this company. Finally, the third model incorporates the farms that an exporter company owns itself. As these farm types are very different in many dimensions like the organisation of the farm, the structure of decision-making and especially the degree of vertical integration of the supply chain, it is necessary to differentiate them. The impact of EurepGAP standards on these three types of farms is analysed based on interviews of 18 large- and medium-scale private farms, 8 exporter owned farms and 46 smallholder farms in Kenya.
