Healthy soil is the foundation of resilient landscapes, sustainable food systems, and climate adaptation in Africa’s drylands. As a unifying element across climate, nutrition, biodiversity, and restoration agendas, soil health plays a critical role in realising the ambitions of the African Union’s Great Green Wall Initiative (GGWI). With over 65% of productive land degraded and soil erosion undermining agricultural productivity, smallholder farmers across the continent face compounding vulnerabilities. The GGWI Strategy (2024–2034) recognises soil health as central to reversing land degradation and building long-term resilience, aligning closely with the Africa Fertiliser and Soil Health Action Plan (AFSH-AP) (2023 – 2033) and broader goals outlined in the Ten-Year Comprehensive Africa Agriculture Development Programme (CAADP) Strategy and Action Plan (2026-2035).

In light of the increased political support, international attention, and financial investment in restoration, the question this ‘Insight Brief’ aims to address is: How is evidence being used and integrated into (ecosystem) restoration processes and how can it be better utilised to inform and improve restoration action at scale? This brief seeks to highlight current issues around evidence in restoration with a view to providing input for future restoration projects and programmes under the UN Decade on Ecosystem Restoration, but also the diverse plans identified above.
