Guiding Acid Soil Management Investments in Africa
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.
Soil Information Systems Review: a process toward strengthening national soil information systems
The Bill & Melinda Gates foundation has made great progress in the past ten 10 years in exploring new and innovative digital soil mapping technologies and national soil information systems (SIS) in Africa and South Asia to help organise new and existing soil information. However, constraints within countries stop the SIS from being sustainable and adaptable. The foundation is now looking for ways to make the SIS more responsive to local demand. CABI is working with partners to identify what intervention approaches have worked, and which have not, which solutions work best and where to take innovation to scale for SIS development. The process will involve engagement with key stakeholders and decision makers in various countries through an iterative process.
