Scale up land restoration to address widespread desertification across northern Nigeria
Executive Summary
922,717.86 ha under restoration to date; vegetation cover +3.6%; ~70 million people facing desertification nationally; project active in 19 of 36 states
This signal falls under the Land restoration / natural resource management sector in Nigeria, classified as a Program Demand, Scaling Demand — indicative of a systemic gap requiring coordinated institutional response.
Core demand gap identified: Land restoration to date (922,717.86 ha, +3.6% vegetation cover) covers only part of the ~70 million people facing desertification, and the ACReSAL project is active in just 19 of Nigeria's 36 states, leaving most desertification-affected areas without restoration investment.
Impact areas intersected: Environmental Health & Biodiversity, Climate Adaptation & Mitigation. Key indicator: Land under restoration = 922,717.86 ha; population facing desertification = 70,000,000.

Investment Implications
The signal's high priority classification (score 88/100) and high evidence base position Nigeria as an actionable investment context. With 2 peer signals in Nigeria, this demand cluster warrants coordinated investment response.
Addressing the demand captured in this signal requires coordinated action across government, CGIAR research partners, and development finance institutions active in Nigeria. Blended finance structures can reduce implementation risk and mobilise private sector participation at scale.
Research Needs
- 1.Baseline assessment to quantify and confirm the demand gap: Land restoration to date (922,717.86 ha, +3.6% vegetation cover) covers only part of the ~70 million people facing desertification, and the ACReSAL project is active in just 19 of Nigeria's 36 states, leaving most desertification-affected areas without restoration investment.
- 2.Stakeholder mapping and willingness-to-invest study in target National (19 of 36 states + FCT) geographies
- 3.Climate scenario and risk modelling for the intervention area through 2030
- 4.Monitoring & evaluation framework design for proposed interventions
- 5.Cross-country learning synthesis from comparable CGIAR programmes addressing Degraded Land
Recommended Actions
Commission a rapid feasibility assessment for priority interventions addressing Degraded Land in Nigeria. Allocate co-financing in the next national budget cycle.
Deploy field research team for needs assessment and evidence verification in Nigeria. Publish findings as an open-access technical brief for investor and government use.
Structure concessional facility to anchor private co-investment. Engage AFDB, World Bank, and IFAD via the Catalyst Lab investment pipeline dashboard for Nigeria.
Signal verified against IWMI QA Protocol v3.2. Confidence score incorporates source diversity index, temporal recency weighting (half-life: 18 months), and geographic specificity.
Scheduled re-verification: September 2026. Signal classification will be updated if new evidence materially changes the evidence weight or priority ranking.
