PHL INTELLIGENCE HUB

Understand the crisis. Know the solution.

The PHL Intelligence Hub is the definitive evidence base for post-harvest loss interventions in Sub-Saharan Africa. We aggregate peer-reviewed research, field trial data, and World Bank estimates to provide a clear path forward for food security.

📄 457 studies reviewed — hermetic storage evidence base

📅 Updated 2025–2026 — latest peer-reviewed data only

🌍 4 countries covered — Nigeria, Kenya, Ghana, Uganda

THE BASICS

The 37% that never reaches a table.

Post-harvest loss (PHL) is the measurable qualitative and quantitative decline in a crop from the moment of harvest to the point of consumption. In sub-Saharan Africa, this systemic leak undermines food security, farmer income, and climate resilience.

1.

Harvesting — Mechanical damage or poor timing.

2.

Handling — Bruising during loading and transport.

Storage — Pests, mold, and moisture in traditional granaries.

3.

Processing — Inefficient threshing or milling.

4.

Transport — Spoilage due to heat and lack of cold chains.

5.

Marketing — Losses at wholesale and retail points.

RESEARCH LIBRARY

Verified data. Crop by crop. Country by country.

Post-harvest loss (PHL) is not a single problem; it is a series of specific failures across the supply chain. Our research hub maps these failures to proven storage and logistics interventions.

Maize (Kenya & Nigeria)

15–25%

<1%

Avg. Seasonal Loss

Most maize loss occurs during on-farm storage due to the Larger Grain Borer and maize weevils. Moisture mismanagement leads to aflatoxin contamination, rendering the remaining grain toxic.

Loss with Hermetic Storage

Cowpea (Nigeria & Ghana)

40–100%

0%

Loss if untreated (3 months)

Cowpea is highly vulnerable to bruchid beetles. Without chemical or hermetic intervention, a farmer can lose an entire annual harvest within 90 days of storage.

Loss in PICS / Hermetic Bags

What the cowpea result proves: That the barrier to food security isn't just yield—it's the biological clock of pests that hermetic technology stops entirely.

Horticulture (Tomatoes, leafy greens)

40–50%

10–15%

Loss in Traditional Logistics

The issue for fresh produce is the 'broken middle'—the time between harvest and market where heat accelerates rot. Evaporative cooling and solar-refrigeration are the critical solutions here.

Loss with Cold-Chain Aggregation

Paddy Rice (Nigeria, Ghana, Uganda)

10–18%

<3%

Loss in Traditional Milling

Rice loss is largely 'hidden'—it happens during thrashing and drying, resulting in low head-rice recovery. Targeted logistics interventions can recover thousands of tons for domestic consumption.

Loss with Modern Parboiling
