New research by CABI reveals that just five invasive alien species are causing US$0.9 – 1.1 billion in economic losses to smallholder farmers across six eastern African countries each year, equating to 1.8% – 2.2% of total agricultural GDP for the region. These losses are expected to grow to $1.0 – 1.2 billion per year over the next 5-10 years, highlighting the urgent need for coordinated responses at regional, national and international levels.
New research published in the open-access journal Global Food Security estimates the alarming level of economic losses suffered by smallholder farmers each year in eastern Africa, to a handful of species that have become damaging crop pests since their introduction to the region. These few invasive species can have devastating impacts on important staples such as maize, but also high-value crops including tomatoes, peas and green beans.
Invasive species cause widespread devastation and huge economic losses to smallholder farmers across the world, especially in sub-Saharan in Africa. Invasive species not only directly undermine farmer’s ability to achieve food security, they also affect smallholder agribusiness making farmers unable to link to profitable food value chains and international agricultural trade networks.
Last year, one of the strongest El Niño events ever recorded caused significant changes to weather patterns around the world. Southern and Eastern Africa were hit particularly hard and suffered some of the worst drought conditions for decades, with as little as a quarter of the expected rainfall in the last few months of the year1. Drought is still having devastating impacts on crop yields in Africa, and humanitarian crises have been declared in the worst hit countries.
On the 6 of March 2017, the Honourable Minister of Agriculture Land and Fisheries of Trinidad and Tobago, Mr Clarence Rambharat, and his team met with CABI Plantwise Regional Coordinator, Dr. Yelitza Colmenarez and with the USDA representative for the Caribbean Mr. Wayne De Chi , in order to review and restructure Plantwise activities in the country. “Food security is one of our national priority areas and it’s important to keep supporting the Plantwise activities in the country in order to ensure farmers are getting the technical advice needed”, the Minister said.
The Sri Lankan e-plant clinic pilot, which launched in 2015 at 10 clinics in Central Province, was extremely successful in minimizing the time as well as workload of plant doctors performing data management tasks. As a result of these and various other benefits established over the last 2 years, the e-plant clinic network has been scaled up to Northern, Eastern and Western Provinces with around 66 e-plant clinics in operation, and over 86 plant doctors trained to date. The target is to have 140 e-plant clinics across Sri Lanka by the end of the year.
All farmers are affected by pests and diseases attacking their crops, but smallholder farmers and their dependents in low- and middle-income countries are disproportionately affected. To put it in perspective, there are about 500 million smallholder farmers worldwide who feed about 70% of the world’s population. When you cultivate less than a hectare (2.5 acres) of land and rely on your crops for both sustenance and income, fighting pests can become a battle for life and death. International trade and climate change are exacerbating the problem by altering and accelerating the spread of crop pests.
Occasionally, when a particularly destructive pest surfaces, it can make headline news. Last year it was reported that the tomato leaf miner moth…
Bond, a UK association promoting, supporting and representing the work of international development organisations, announced the CABI-led Plantwise programme as the joint winner of its 2017 Innovation Award. The award showcases organisations, coalitions or initiatives that are taking inventive approaches as they chart a course through a complex and changing external environment in international development.
