Measuring the livelihood impacts of invasive alien species in East Africa

Although a lot is known about the biodiversity impacts of introduced species in East and southern Africa, very little is known about the livelihood impacts that they have on communities that depend on the goods and services provided by ecosystems. The aim of this project is to determine the negative socio-economic impacts of selected invasive alien plants on poor rural communities, especially farmers, in East and southern Africa.

Toolkits for invasive plants in Laikipia, Kenya

Many exotic plant species introduced to Laikipia County, Kenya, have escaped cultivation and threaten biodiversity. Little is currently known however, about the presence of invasive species or their impact. Without this type of information, it is unlikely that various stakeholders will take action to effectively manage this threat. This project aims to fill some gaps and increase knowledge of invasive species in Laikipia for pastoralists and those actively involved in biodiversity conservation.

Controlling pest pear in Laikipia

Pastoralists in northern Kenya are heavily dependent on livestock. Their lives are being devastated by the non-native cactus Opuntia stricta. This weed has invaded the last good grazing land and when livestock and wildlife eat its fruits the spines can cause infection and death. Chemical and mechanical control methods are expensive and impractical, so we are helping to introduce a new sustainable method: a sap-sucking insect that feeds solely on the cactus.

Managing Maize lethal necrosis disease in eastern and central Africa

Maize lethal necrosis disease (MLND) negatively affects maize crops and their seeds and is threatening food and economic security in East and Central Africa. This project researched solutions to minimize or eliminate the risks and effects of the disease in the region. Through use of various channels to reach stakeholders along the value chain, CABI disseminated information on the threat of the disease and ways to manage it.

Australia-Africa plant biosecurity partnership

Agricultural trade is a powerful engine for economic growth, poverty alleviation and food security but diseases are impacting it. Countries are therefore looking for ways of making agricultural trade secure. This initiative aims to facilitate trade by addressing plant pest and disease problems that hinder agricultural exports and threaten food security. The programme focusses on strengthening plant biosecurity skills in in Africa based on the experiences of Australian experts.

Promoting good seed in East Africa

African Indigenous Vegetables (AIVs) are key to food security and income generation in Africa and are increasing in demand. In this project, not only did CABI’s project team promote their consumption and generate more demand, it also built awareness of the vegetables and seeds, improved access to them and developed new varieties.
