Invasive species impact the livelihoods of the rural poor who are dependent on natural resources for income and survival. They also undermine international development investment. CABI is developing an ambitious solution to this complex problem. 

Prosopis invasion

Many exotic trees and shrubs have been introduced into Africa and become destructive invasive species. They're reducing native biodiversity and limiting the livelihoods of those that live in rural communities. CABI is trying to mitigate these impacts in East Africa by generating and sharing knowledge on their effects and finding ways that they can be controlled.

Managing invasive species in selected forest ecosystems of South East Asia

Study group in the forest

Invasive species are threatening forest habitats in South East Asia. They also indirectly affect the livelihoods of millions of people who depend on forests for food, commodities and energy. CABI and the United Nations Environment Programme (UNEP), in collaboration with partners, have developed a project aimed at conserving globally important forests in the region. The initial aim is to enhance the capacity of Cambodia, Indonesia, Philippines and Vietnam to manage their invasive alien species.

Biological control of invasive plants in East Africa

Non-native plants are invading parts of East Africa and having significant impacts on biodiversity and livelihoods. Resource poor farmers don’t have the money to buy pesticides which can have negative impacts on people and the environment. CABI is therefore working to reduce the negative impacts of Chromolaena odorata and Parthenium hysterophorus in Tanzania, Salvinia molesta in Uganda and Mimosa pigra in Zambia.

Controlling the invasive blackberry on the Galapagos Islands

Rubus niveus Galapagos fruit

The unique wildlife and farmland on the Galapagos Islands are threatened with a non-native invasive weed. The invasive blackberry now covers around 30,000 hectares and can grow up to 3m tall. CABI scientists are searching for potential biocontrol agents from the Asian native range of the blackberry to introduce here.
