Continue expanding irrigated area and closing the household water-access gap in ACReSAL states
Executive Summary
25,298 ha irrigated area developed; 965 solar-powered boreholes drilled; 79.1% of households report improved water access (20.9% gap); 72.7% report higher crop yields; 82.2% report increased income
This signal falls under the Irrigation and rural water supply sector in Nigeria, classified as a Program Demand, Scaling Demand — indicative of a systemic gap requiring coordinated institutional response.
Core demand gap identified: About 20.9% of ACReSAL beneficiary households still lack improved water access despite 25,298 ha of irrigation development and 965 solar boreholes drilled, leaving a residual water-access gap even among program participants.
Impact areas intersected: Climate Adaptation & Mitigation, Poverty Reduction, Livelihoods & Jobs. Key indicator: Irrigated area = 25,298 ha; improved water access = 79.1% (gap ~20.9%); solar boreholes = 965.

Investment Implications
The signal's high priority classification (score 83/100) and high evidence base position Nigeria as an actionable investment context. With 3 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: About 20.9% of ACReSAL beneficiary households still lack improved water access despite 25,298 ha of irrigation development and 965 solar boreholes drilled, leaving a residual water-access gap even among program participants.
- 2.Stakeholder mapping and willingness-to-invest study in target 19 covered states 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 Irrigation & Water Access
Recommended Actions
Commission a rapid feasibility assessment for priority interventions addressing Irrigation & Water Access 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.
