PUTTING PARTICIPATORY DOMESTICATION INTO PRACTICE IN WEST AND CENTRAL AFRICA

ABSTRACT The World Agroforestry Centre (ICRAF) has been working in the African Humid Tropics (AHT) since 1987. Despite its natural wealth, small-scale farmers of AHT are among the poorest people in the world and have relied on extractive harvesting of forest products and traditional shifting cultivation for their food and other needs. After years of severe deforestation, alternatives now have to be found as land pressure has increased and commodity prices of cash crops have declined. To overcome these problems, the Participatory Domestication of high-value indigenous fruit, nut and medicinal trees is seen as one way of empowering rural households to improve their own situation. Many products of indigenous trees have existing local and regional markets, with additional potential niches in international commerce. In Participatory Domestication, villagers are helped to develop local nurseries, taught skills of vegetative propagation, and assisted with the technical implementation of selecting superior trees for cultivar development, that meet specific market-oriented ‘ideotypes’. Farmers are enthusiastically adopting these techniques and are thereby improving their own livelihoods. The most successful community is expecting to make

US 10,000 in 2005 from the sale of improved cultivars from its nursery. The AHT tree domestication programme started in two villages in 1998, now 42 villages in two Provinces of Cameroon are active partners, and the programme has been extended to other countries. Currently, about 5000 farmers are practising participatory tree domestication techniques: 3500 in Cameroon, 1000 in Nigeria and 500 in the Democratic Republic of Congo. The programme has also started in Equatorial Guinea and will soon be expanding to Ghana, Guinea Conakry, Sierra Leone and Liberia. This paper describes the steps used to implement a participatory approach to tree domestication, and the lessons learnt. It also examines the perceived advantages and disadvantages of domestication, as well as the constraints and opportunities. The critical importance of local processing and value-adding for improved storage of products with short shelf-life is discussed as a means to ensure that the market for agroforestry tree products expands in parallel with the supply.

Impacts of participatory tree domestication on farmer livelihoods in West and Central Africa

Many studies have stressed the importance of trees to rural households. Few, however, have focused on actual numbers and densities of trees in different land-use systems. Based on community-level participatory research in six communities, semi-structured household interviews and full-farm fruit tree inventories, this study aims to understand farmers’ tree-planting strategies. Relationships between the diversity, number and density of fruit trees and farm size, land-use system, land tenure, distance from the homestead, proximity to the forest, market access and household characteristics are investigated. The key factors determining the differences in tree-growing strategies between communities appear to be market access, land use and access to forest resources. Within communities, differences between individual households were less easy to explain but tenure was important as was farm size. Smaller farms had higher fruit tree densities, a relationship that was particularly strong in communities with good market access. Overall there was a great deal of variability both within and between communities and many of the factors affecting tree-planting decisions were found to be highly inter-related. Despite this complexity, trees on farm play an important role in rural households livelihoods. Therefore, expansion of tree cultivation should be recognized as a promising pathway to achieve increased income and food production by policy makers and extensionists alike. In addition to improved tree propagation and management techniques, farmers should be strengthened in the processing and marketing of agroforestry tree products and more emphasis should be placed on the development of tree enterprises. By doing so, farmers will be able to earn a more important and consistent income from fruit trees, contributing to the Millennium Development Goals.

Policy and Legal Frameworks Governing Trees: Incentives or Disincentives for Smallholder Tree Planting Decisions in Cameroon?

ABSTRACT Research on participatory domestication of indigenous trees in West and Central Africa started in 1996 with the objectives of increasing incomes of rural communities and improving their livelihoods by cultivating indigenous trees and developing strategies for marketing the produce. Though the study was conducted in Democratic Republic of Congo, Equatorial Guinea, Gabon, Nigeria, the present paper only presents data from Cameroon. In Cameroon, the original pilot nurseries have subsequently developed and grown to become Rural Resource Centres providing training in a wide range of skills as well as being the focal points for the diffusion of innovations. Some 200 village nurseries are now active and have become on-farm enterprises producing planting material both for local use and for marketing. Over the years, rural communities have increasingly reported improvements in their livelihoods, diet, health, income generation which have transformed their lives and given them encouragement for a better future. Livelihood surveys conducted in 2008 involved 298 farmers from 15 communities. Interestingly, one of the impacts has been that some young people have chosen to stay in their villages rather than to seek off-farm employment in local towns. Since 2008, tree domestication in Cameroon has also been integrated in a wider rural development programme in the West and North-West Regions, based on the concepts of multifunctional agriculture. This integrated approach to meeting the needs of poor rural communities is further empowering smallholder farmers to develop superior cultivars of indigenous fruits and nut trees and to produce planting stock of leguminous trees and shrubs for soil fertility replenishment. It has also encouraged entrepreneurism in the processing of agricultural products as well as tree products, and stimulated the development of markets for agroforestry tree products. Currently, over 6000 farmers from around 300 communities are engaged in this integrated rural development programme. This has been achieved by enhancing the capacity of technicians from NGOs, extension services and community-based organizations in the skills needed for tree domestication, agroforestry and value-addition at the community level.

Getting Trees Into Farmers’ Fields: Success of Rural Nurseries in Distributing High Quality Planting Material in Cameroon

Agroforestry and planting trees on farmers’ fields have been reported as important elements in a strategy to meet the millennium development goals of poverty reduction and climate change improvement. However, their uptake seems to be constrained by factors both internal and external to the household and related to the policy and legislative environment. This paper examines the impact of these factors on farmers’ decisions to plant trees. Cameroon is used as a case to analyse whether existing policies and legislation governing trees support or discourage tree planting, using qualitative content analyses. Although their mission papers and statements suggest most national government policies in Cameroon address tree planting and agroforestry, actual legislation designed to follow up the policies mostly contradicts the poverty reduction goals. Often legislation and regulations are more conservation-oriented and do not provide a clear procedure to distinguish between products from trees found in the wild and those gathered from farmers’ fields.

Effectiveness of Grassroots Organisations in the Dissemination of Agroforestry Innovations

Availability of high quality tree planting material within proximity of farmers and at affordable prices is one of the prerequisites for larger uptake of tree cultivation. This study examines whether rural small-scale nurseries can produce a diversity of tree planting material and whether resource-poor farmers have access to it. Twelve nurseries supported by the tree domestication program in the West and North-west regions of Cameroon were compared to 12 nurseries in similar conditions, but not in contact with the program. Nurseries using the domestication approach were found to provide tree planting material that responds better to farmers’ needs in terms of quantities, species and propagation methods used. Their clientele is more diverse including farmers from the communities where the nurseries are located, but also from far beyond. However, prices of vegetatively propagated material were considered the most prohibitive factor. It is concluded that tree planting initiatives should refocus efforts towards technical training and business support to small-scale nurseries to increase efficiency. Research efforts should look for ways of reducing production costs and improving nursery productivity.

Ecological Interactions and Productivity in Agroforestry Systems

Eradicating extreme poverty and hunger is the first Millennium Development Goal (MDG) for a reason: none of the other MDGs can be met without food security and economic development. Because 75 percent of the poor in developing countries live in rural areas, strengthening the agricultural sector can not only improve access to nutritious food, it does more – at least twice as much – to reduce rural poverty than investment in any other sector (FAO, 2011). The role of extension in this battle is clear; there is a great need for information, ideas and organisation in order to develop an agriculture that will meet complex demand patterns, reduce poverty, and preserve or enhance ecological resources.

Understanding the Roles of Forests and Tree-based Systems in Food Provision

Ecological Interactions (hereafter, interactions) between the components of an agroforestry system occur when one component influences the performance of other components, and that of the whole system. Interactions in agroforestry can be positive, neutral or negative. A positive interaction is the complementarity between woody and herbaceous components in resource acquisition. Competition between components for water, nutrients and light is one example of negative interactions. Allelopathy, damage caused by animals or pests, and disease transmission are other negative interactions. Neutral interactions occur in agroforestry systems when the different components of the system exploit the same pool of resources, and increases in capture by one species result in a proportional decrease in capture by the associated species. Trees contribute to productivity in agroforestry through fertilization, and soil conservation. Tree contribution to fertilization is through the symbiotic fixation of nitrogen, root turnover, nutrient cycling, and their involvement in the formation of the humus layer. Maintenance of the physical properties of the soil is accomplished through erosion control and the stabilization of the soil by the roots.

Scaling-up Sustainable Land Management Practices through the Concept of the Rural Resource Centre: Reconciling Farmers' Interests with Research Agendas.

Forests and other tree-based systems such as agroforestry contribute to food and nutritional security in myriad ways. Directly, trees provide a variety of healthy foods including fruits, leafy vegetables, nuts, seeds and edible oils that can diversify diets and address seasonal food and nutritional gaps. Forests are also sources of a wider range of edible plants and fungi, as well as bushmeat, fish and insects. Treebased systems also support the provision of fodder for meat and dairy animals, of “green fertiliser” to support crop production and of woodfuel, crucial in many communities for cooking food. Indirectly, forests and tree-based systems are a source of income to support communities to purchase foods and they also provide environmental services that support crop production. There are, however, complexities in quantifying the relative benefits and costs of tree-based systems in food provision. These complexities mean that the roles of tree-based systems are often not well understood. A greater understanding focuses on systematic methods for characterising effects across different landscapes and on key indicators, such as dietary diversity measures. This chapter provides a number of case studies to highlight the relevance of forests and tree-based systems for food security and nutrition, and indicates where there is a need to further quantify the roles of these systems, allowing proper integration of their contribution into national and international developmental policies.

Agroforestry for Soil Conservation

Abstract Purpose: Formal agricultural research has generated vast amount of knowledge and fundamental insights on land management, but their low adoption has been attributed to the use of public extension approach. This research aims to address whether and how full participation of farmers through the concept of Rural Resource Centre (RRC) provides new insights for the development of alternative and farmers-based extension methods. Design/Methodology/Approach: Using the Concept of RRC, this research assesses the role of farmers in on-farm demonstrations and scaling-up of land management practices, and investigates effective ways to enhance beneficial interactions between researchers, extension workers and farmers in view of improving adoption. Findings: The findings suggest that farmers can effectively participate in demonstrations and scaling-up of agricultural practices. This participation is enhanced by judicious incentives such as higher crop yields that motivate farmers and influence adoption. The current success of the approach stems from the fact that farmers, extension workers and researchers jointly implement the activities and their different aims were achieved simultaneously: scientific results for researchers, better agricultural practices for extension workers, and economic success and free choice for farmers. Practical implications: This research concludes that farmers have the capacities to play an innermost role in demonstrations and scaling-up of agricultural practices. However, there is a need to build and strengthen their capacities to facilitate their participation and contribution. Originality/Value: The article demonstrates the value of the preponderant role of farmers in on-farm demonstrations and scaling-up practices by exhibiting the beneficial interactions between researchers, extension workers and farmers.
