NRI Cassava Programme

The African Cassava Whitefly Project is searching for answers to significantly reduce the cassava-whitefly abundance in the cassava-growing regions of East and Central Africa. Outbreaks of the African cassava whitefly are responsible for serious crop losses in nine East and Central African countries resulting in hunger, recurrent famines and annual losses of more than USD1.25 billion.

Cassava: Adding Value for Africa (CAVA II) is a project that aims to increase the incomes of at least 200,000 value chain actors, especially smallholder farmers and processors in Nigeria, Ghana, Tanzania, Uganda and Malawi, by at least USD177 million in five years. This will be achieved through stimulating sales of more than two million tons of cassava into HQCF and other cassava product value chains.

The Cassava: Adding Value for Africa (C:AVA) Project seeks to develop value chains for High Quality Cassava Flour (HQCF) in Ghana, Tanzania, Uganda, Nigeria and Malawi to improve the livelihoods and incomes of at least 90,000 smallholder households as direct beneficiaries including women and disadvantaged groups.

CassavaGmarkets is a project that aims to improve the livelihoods of smallholder cassava farmers through better access to growth markets. It will explore climate change, pest and diseases, processing and gender. The countries this project will focus on are Ghana, Nigeria, Tanzania, Uganda and Malawi. India will also provide expertise.

Gratitude (Gains from Losses of Root and Tuber Crops) , led by the Natural Resources Institute (NRI), University of Greenwich UK, in collaboration with 15 other organisations, sought to help find solutions that will reduce waste from post-harvest losses of root and tuber crops and turn unavoidable waste into something of value.

This project sought to strengthen the science and technology capacity of African Caribbean and Pacific (ACP) countries to use tropical root and tuber crops to contribute to a wide range of development issues. These include food security, poverty reduction, enterprise development and income generation, impacts of climate change and variability, impacts of urbanisation, impacts of the global food crisis and global economic downturn, opportunities provided by biofuels and export development.

This project will develop specific research tools for African cassava virologists and breeders, which will assist their research and work to improve cassava productivity and sustainability in sub-Saharan Africa (SSA). It aims to minimize both the occurrence as well as impact of cassava virus diseases and their associated insect (whitefly) vectors.

Increase the performance of the Cassava Industry in West and Central Africa by enhancing the performance of IFAD-funded national root and tuber crops projects. This will have wider regional impact through dissemination of good practices, technological innovations and policy dialogue and heightening of private sector involvement.

This research project will examine the potential to adapt technologies for cassava production and processing in China for use in Uganda. This project contributes to developing value chains that will benefit small-holder farmers dependent on cassava to improve cassava, production and marketing.

The project addresses opportunities related to improving efficiency and gender equity issues of cassava processing, consumer preferences and the resulting demand for sustainable intensification of cassava production systems.

This project builds on the strength of partners across the cassava value chain: both pre-harvest (disease and pest resistance, breeding) and post-harvest (processing and markets). LimitCBSD explores cassava brown steak disease (CBSD) diagnostics, epidemiology, tissue culture and use of advanced molecular tools to identify sources of resistance to the disease.

This project aims to identify CBSD resistance in 25 elite cassava lines in five target countries and develop a commercial seed system for cassava in Tanzania.

This research project aims at determining the true retention of carotenoids in yellow-fleshed cassava during processing into gari, fufu and determination of nutrients of importance in cassava leaves. This will lead to evidenced based processing methods that reduce Vitamin A loses during processing.

To exploit virulent strains of the endosymbiotic bacteria, Wolbachia, as a novel biocontrol agent for controlling the harmful insect pest, whitefly in order to protect African cassava from destructive whitefly-transmitted plant viruses.
