  • Enhancing the livelihoods of the rural and urban poor through improved market access for sweet potato

    Objectives: To maximise economic returns and improve food security of poor farmers through the development of a range of institutional arrangements that effectively and sustainably improve access to post-harvest knowledge and market opportunities. Background: Sweet potato (Ipomoea batatas) is an important food security crop in many of the poorest regions of the world. The crop is grown in over 100 countries of the world, covering an estimated total area of 9.2 million ha, with an annual global production of around 125 million tonnes. It is the world's seventh most important staple crop. Almost 95% of the total production is in developing countries (CIP 1996). Past and current production trends suggest that sweet potato output in developing countries is increasing, for example in Africa it is estimated that it is presently increasing at about five percent per year (CIP 1996).

  • Improving farmer and other stakeholders' access to quality information and products for pre- and post- harvest maize systems management in the Southern Highlands of Tanzania

    Objectives: New knowledge is generated and promoted into how national innovation systems can be mobilised to sustain uptake and adoption of CPH knowledge for the benefit of the poor. Specifically to provide innovative learning tools and products, to address the pre- and post- harvest training needs identified by maize seed system stakeholders in the Southern Highlands of Tanzania, using both existing and novel promotion pathways. Background: While working on improving farmers' access to and management of disease resistant maize cultivars, the demand for further information and post-harvest training tools for use by stockists, public sector service providers, private companies and farmers was raised again and again, reflecting the changing context in which these stakeholders are operating.

  • Improving farmers access to and management of maize seed in the Southern Highlands of Tanzania - Phase 2

    Objectives: Promotion of strategies to reduce the impact of pests and improve quality and yield from High Potential cropping systems for the benefit of poor people. Background: A range of maize cultivars was evaluated in 16 villages on 80 farmers' fields, and Uyole-bred maize hybrids showed high levels of tolerance to Grey Leaf Spot (GLS) as well as a high grain yield potential. These materials were also generally ranked relatively highly by farmers, under high input regimes, in Mbozi, Njombe and Iringa districts. In lower-lying Mbarali district, however, open pollinated varieties showed better adaptability. In addition, none of the varieties evaluated in Mbarali appeared to possess the level of resistance required to withstand the Maize streak virus (MSV) pressure experienced in some parts of the district.

  • Promotion of neglected indigenous vegetable crops (IV) for nutritional health in Eastern and Southern Africa (Phase II)

    Goal: To improve household food security of resource-poor groups in Eastern and Southern Africa by; 1) Safeguarding biodiversity of indigenous vegetables (IVs), 2) reducing malnutrition and poverty among small-scale farmers and consumers through promotion, production and consumption of IVs and 3) diversifying and stabilizing farmers’ income and nutritional health through higher quality seed and improved cultivation practices of IV crops Purpose: To enhance genetic resource base, technology dissemination and improved seed of IVs to safeguard biodiversity for better health, nutrition and improved income
