Fostering partnerships to combat fall armyworm

IMG_0155

Since 2017, CABI has been heavily involved in the international effort to develop and implement a continental framework for tackling fall armyworm in Africa. Initial meetings resulted in the development of a draft framework, which identified roles for different organisations involved in fall armyworm management globally and on the African continent, including CABI. This has culminated into what has officially become known as the Framework for Partnership for Sustainable Management of the Fall Armyworm in Africa.

Invasive plants to devastate annual wildebeest migration

serengetiAccording to new research, scientists found that a number of invasive alien plant species initially introduced as ornamental plants at tourism facilities are now spreading rapidly throughout the Serengeti-Mara ecosystem, posing a major threat to wildlife, including the annual wildebeest and zebra migration as well as a range of other plant and animal species.

The locust invasions devastating Niger

It is the end of December 2016, with clear skies over Niger. But as 2017 draws near prospects are grim for some 500 residents in Bani Kosseye, a village 80km from the capital Niamey. Agricultural production has been poor here, and families’ meagre stocks are expected to run out within a few weeks. People already fear famine. Continue reading

Where to find CABI’s open-access information on fall armyworm

cabi_invasives_faw

The fall armyworm, Spodoptera frugiperda, is making headlines worldwide for all the wrong reasons. The caterpillar crop pest, native to the Americas, was reported in Africa for the first time last year and is now rapidly marching across the continent. It is a voracious pest of maize and other staple crops and has already destroyed tens of thousands of hectares of farmland. As such, it risks devastating smallholder livelihoods throughout Africa. Given that CABI scientists predict it could reach Europe and Asia in a matter of years, it looks set to quickly become a global problem.

The case for action against fall armyworm is overwhelming. On the ground, CABI will support national extension services to help farmers identify the pest quickly and accurately, contribute to awareness-raising and conduct studies to work out the best ways to control it that are not overly dependent on insecticides. Alongside these efforts, CABI also has a range of freely-available materials to help people understand and manage fall armyworm. Continue reading

New Strategy Receives Thumbs Up

This week in Douala, Cameroon, the General Assembly of the African Union’s InterAfrican Phytosanitary Council (IAPSC) gave the thumbs up to IAPSC’s new strategic plan. IAPSC Director Dr Jean Gerard Mezui M’Ella thanked all the organisation’s partners who had assisted in the preparation of the plan, especially FAO’s Regional Office for Africa for funding the work. Titled “For Better Plant Health in Africa”, the plan identifies four key impact areas, and names a number of partners, including CABI, whose support will be important in its operationalization.

Following on from earlier discussions with IAPSC, CABI Africa’s Roger Day made a presentation on “A Plant Health Management System (PHIS) for IASPC”, corresponding to output 2.3 of the strategy. The ideas were well received by the General Assembly, which immediately appointed a small task force to develop a proposal as a basis for mobilising resources. The General Assembly also adopted a resolution saying it “Welcomes the cooperation between CABI and IASPC on Plant Health Information Systems, and urges them to develop further the ideas for putting in place an effective PHIS, and calls upon international partners to avail financial and technical resources for implementing such an important project”.

Ebola and IAS

A conversation with Dr Arne Witt

Dr Arne WittThe recent outbreak of Ebola virus disease in West Africa made headline news around the world. During the outbreak this fatal disease, endemic to parts of Central and West Africa, rapidly spread from Guinea, Sierra Leone, and Liberia to other countries in the region such as Nigeria, Mali and Senegal and then further afield to the USA, UK and Spain, mainly through infected health workers. This prompted decisive action from governments around the world and led to the implementation of strict controls at most national points of entry – as a result of this action and increased awareness, the further spread of this disease was effectively halted. No new infections have been reported for a number of months now but the cost has been significant – more than 10,000 people lost their lives, mainly in Guinea, Sierra Leone, and Liberia. However, it is highly probable that without significant interventions the costs could have been far higher. For example, the outbreak of bubonic plague or Black Death in Europe in the 17th century resulted in the death of 34 million people. The accidental introduction of potato blight, a crop disease which affects potatoes, from the Americas to Ireland in the mid-1800s contributed to the starvation of about 1 million people. Rinderpest, a disease affecting livestock was accidentally introduced to Africa from Asia in the late 19th century resulting in the deaths of, it is claimed, a third of the human population of what is now Ethiopia and two-thirds of the Maasai, an ethnic group of pastoralists in East Africa who are totally dependent on livestock. We may ask what Ebola, potato blight and rinderpest have in common – well obviously they have all have had a devastating impact on humanity but what binds them all together is that they are all INVASIVE ALIEN SPECIES (IAS). Fortunately, due to concerted efforts by a range of agencies rinderpest has been eradicated from the planet but as a result of increased trade, travel and tourism more and more species are being moved around the world and many are establishing and are continuing to have devastating impact on livelihoods.
