In the distantly-related Chinese cabbage (Brassica rapa), a potentially durable TuMV disease resistance trait was identified by Professor John Walsh at the University of Warwick, while work by Dr Charlotte Nellist, of NIAB EMR, UK, Dr Bill Briggs, of Syngenta, and Prof Walsh elucidated the novel mechanism of TuMV resistance.
CABI has told the African Green Revolution Forum (AGRF) 2019 that investment in agritech needs to double to at least $10bn a year if the world’s smallholder farmers are to help feed a global population expected to reach 10 billion by 2050.
Dr Dennis Rangi, CABI’s Director General, Development, speaking as part of a panel discussion on the subject of digital innovations to strengthen the resilience for smallholders in African food systems, said the financial burden must be met by the private sector if global food security is to be ensured and world poverty and hunger eradicated.
Between 2011 and 2015, CABI set up 22 Trichogrammarearing facilities as part of a project to promote the use of biologically-based Integrated Pest Management (IPM) for rice and maize crops. In addition to creating the Trichogramma rearing facilities, IPM strategies for rice and maize were developed in Southwestern China, Laos and Myanmar.
Pests, which threaten to destroy key cash and food security crops including maize, tomato and beans, are to be prioritized as part of an integrated pest management strategy using state-of-the-art space-age technology.
Scores of smallholder farmers in Rwanda are the latest to benefit from the CABI-led consortium, funded by the UK Space Agency and the Global Challenges Research Fund with co-funding from the CABI-led Plantwise, that is using a combination of earth observation technology, satellite positioning and plant-pest lifecycle modelling to provide an evidence-based Pest Risk Information Service (PRISE).
CABI is today calling for greater investment in food security programmes to help stem the global rise in hunger following the publication of a UN report which says more than 820 million people worldwide are still going hungry.
Insects and diseases that damage crops are probably present in many places thought to be free of them, new research shows.
Pests that have not been reported in a certain area are usually assumed to be absent, but analysis by the University of Exeter shows many pests are “currently unobserved, but probably present” (a likelihood of more than 75%).
The study identified large numbers of pests in this category in China, India, southern Brazil and some countries of the former USSR.
Farmers in Malawi are the latest to benefit from a CABI-led consortium, funded by the UK Space Agency, which is providing a Pest Risk Information Service (PRISE) to fight pest outbreaks that could devastate crops and livelihoods across the country.
The service, which uses state-of-the-art technology to help inform farmers in sub-Saharan Africa – including Zambia, Ghana and Kenya where it is currently operating – gives farmers invaluable information to help them manage pests such as the fall armyworm that is already having a major impact in Africa and South East Asia.
