Saving Tristan’s only native tree and its associated unique buntings
Invasive non-native species are a major threat on oceanic islands due to their vulnerability and endemism, typical of island ecosystems. On Tristan da Cunha, a remote group of islands in the South Atlantic, Brown soft scale, (Coccus hesperidum), an invasive alien scale insect, has infested Tristan’s only native tree, Phylica arborea; and is now threatening the extinction of one of Britain’s rarest bird species, Nesospiza buntings. There is, therefore, an urgent need to find an appropriate method to mitigate the impact of the scale insects and prevent the total collapse of the Phylica forest. The aim of this project is to select and safely test suitable biocontrol agents to reduce scale numbers below a damaging threshold and safeguard Tristan’s endemic buntings.
Digital innovation to protect Colombian coffee farms and farmers
The coffee berry borer (CBB) is the most serious coffee pest worldwide, causing crop damage in excess of $US500 million, annually. In Colombia, 75% of coffee crops are affected by this pest. It directly damages coffee beans, destroying their taste and making them unsaleable. To exacerbate the problem, climate change enables the wider spread of CBB, especially at higher altitudes. To overcome losses, the trend amongst farmers is to intensify their activities and expand growing areas. CABI and partners are producing an alert system that uses climatic data and remote sensing technology to give farmers advance warnings of CBB surges, allowing them time to access and apply controls effectively. The project will also focus on overcoming gender disparities in coffee farming due to reduced participation by women.
Control of fall armyworm in Eastern Africa
In Africa, the fall armyworm is a pest causing significant destruction and devastation to crops. It is estimated to cause 8-20 million tonnes of maize losses each year and due to little knowledge of the pest and ways of managing it, the impacts can be catastrophic. With partners, CABI developed an emergency response strategy that empowered local communities of six target countries to effectively manage and monitor outbreaks in their respective localities, helping to prevent further spread.
African Crop Epidemiology System (ACES)
The increasing frequency and severity of pest (insects, pathogens and weeds) outbreaks are causing huge crop losses in Sub Saharan Africa. Reducing such losses requires the application of robust plant protection measures at farmers’ levels. Pest-mediated crop losses exceed 50% in both West and East Africa, but losses in northwest Europe stand at only approximately 18%. The development and implementation of an efficient, resilient and integrated plant protection system, that is guided by effective surveillance and forecasting of outbreaks, will help provide a timely and effective response and is expected to narrow the yield gap in many countries.
Improving pest management in agroforestry on sloping land
Land in the Democratic People’s Republic of Korea (DPRK) is predominantly mountainous with a high proportion of upland slopes. Agroforestry methods help to maintain sloping land and over 200 established Sloping Land User Groups (SLUGs) already apply these methods. To mitigate associated environmental risks of sloping land, to increase food security of SLUGs and progress slope stabilisation, this project will focus on improving existing management practices of the SLUGs and county tree nurseries, and increasing their knowledge about pest control.
