The effects of soil acidity on agricultural soils in Africa are a major constraint to crop production and sustainable intensification of the African smallholder farming system. To cope, the existing method is to apply blanket or spatially undifferentiated approaches including the use of lime. This project aims to devise interventions to rehabilitate soils in East Africa by understanding and communicating the differences in soil acidity and how to cost-effectively correct them. Based on data, recommendations will guide investments into appropriate and targeted approaches from the public and private sector, ensuring a maximum return on investment for farmers, governments and the private sector. In this project, CABI’s focus is on enhancing access to, and use of, data related to acid soil management including soil and agronomy data which would lead to evidence-based decisions for investments.
Trade in mango, avocado, papaya and citrus within the East African Community region, the European Union and China at import and export levels have been rising. However, meeting the increasing demand is being affected by a number of crop pests and diseases. In East Africa, scale insects – mealybug pests such as Papaya mealybug and fruit tree mealybug – are impacting cultivation and yields. To tackle these pests and increase trade, CABI is working with partners to increase compliance with sanitary and phytosanitary requirements through improved surveillance and management of scale insect pests in East Africa.
