Finance and scale anticipatory drought interventions — small-scale irrigation and drought-tolerant crops — in Zambia's Western Province, which show BCRs exceeding 1 at all district levels
Executive Summary
BCRs for all anticipatory action scenarios exceed 1.0 at provincial and district levels. Combined irrigation + drought-tolerant varieties yields the highest BCR. NPV and avoided relief costs amount to tens of millions of USD. The 2018 drought in Western/Southern Provinces was recorded as one of the worst in recent history; lack of large-scale anticipatory measures led to widespread hardship.
This signal falls under the Maize, drought-tolerant crops, small-scale irrigation / disaster risk finance sector in Zambia, classified as a Policy Demand, Financing/Investment Demand, Scaling Demand, Innovation Demand — indicative of a systemic gap requiring coordinated institutional response.
Core demand gap identified: Western Province remains almost entirely dependent on rainfed agriculture with very little irrigation infrastructure, leaving farming communities exposed to recurrent droughts despite strong economic evidence that anticipatory investment in irrigation and drought-tolerant varieties would reduce losses at BCRs above 1.0.
Impact areas intersected: Climate Adaptation & Mitigation, Poverty Reduction, Livelihoods & Jobs, Nutrition, Health & Food Security. Key indicator: BCR > 1.0 in all districts; avoided losses and relief costs = tens of millions USD; Western Province irrigation area non-irrigated: ~3,000–3,500 ha per district.

Investment Implications
The signal's high priority classification (score 97/100) and high evidence base position Zambia as an actionable investment context. Ranking #1 of 28 signals in Zambia, this represents one of the highest-priority opportunities in the current portfolio.
Addressing the demand captured in this signal requires coordinated action across government, CGIAR research partners, and development finance institutions active in Zambia. 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: Western Province remains almost entirely dependent on rainfed agriculture with very little irrigation infrastructure, leaving farming communities exposed to recurrent droughts despite strong economic evidence that anticipatory investment in irrigation and drought-tolerant varieties would reduce losses at BCRs above 1.0.
- 2.Stakeholder mapping and willingness-to-invest study in target Western Province (Kalabo, Kaoma, Limulunga, Mongu, Nkeyema, Senanga, Sesheke, Shangombo districts) 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 Anticipatory action and disaster risk financing
Recommended Actions
Commission a rapid feasibility assessment for priority interventions addressing Anticipatory action and disaster risk financing in Zambia. Allocate co-financing in the next national budget cycle.
Deploy field research team for needs assessment and evidence verification in Zambia. 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 Zambia.
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.
