Rwanda Maps Cooling Solutions to Save Vaccines and Food

Keeping vaccines at the right temperature can mean the difference between life and death, and Rwanda just took a major step toward making that happen across Africa.

The UK-Rwanda Climate Partnership Conference concluded in March 2026 with concrete solutions to fix gaps in cooling and cold-chain systems. The Africa Centre of Excellence for Sustainable Cooling and Cold Chain hosted the event, bringing together experts to tackle a problem that affects everything from vaccine storage to food security.

The stakes are remarkably high. New mRNA vaccines require temperatures as low as minus 70 degrees Celsius to stay effective. Without proper cooling, these life-saving medicines become useless before they ever reach patients.

Jean Pierre Musabyimana, Director of One Health at ACES, explained why cooling systems matter beyond just keeping things cold. "Through these interactions between humans, animals, and the environment, there is a constant exchange. Our health affects theirs, and theirs affects ours."

The conference tackled real-world challenges through focused sessions. Experts examined vaccine storage, temperature monitoring, medical refrigeration certification, and training for health facility inspectors. They also looked at rural health resilience, where maintaining proper cooling can be especially difficult.

Food systems got equal attention. Dr Natalia Falagán from Cranfield University noted that Rwanda has identified mangoes and avocados as high-value crops with strong development potential. The challenge isn't growing the food but getting it to market while it's still fresh.

One example shows the impact of these gaps. Rwanda produces excellent avocados that fetch high prices internationally, but a single flight cancellation can leave farmers without backup options. Proper cold storage and certification could change that equation entirely.

The conference also addressed workforce training. Professor Judith Evans from London South Bank University said participants identified priorities ranging from ammonia safety to solar cooling technologies. Building local expertise means these systems can be maintained and improved over time.

Interest rates of 17 to 20 percent make it hard for small businesses to invest in cooling equipment, even when they know it would help. Conference participants are now working on financing solutions alongside the technical fixes.

The Ripple Effect

Better cooling systems could transform health care and food security across Africa simultaneously. When vaccines stay cold and fresh food reaches markets, entire communities benefit. Fewer children die from preventable diseases, farmers earn fair prices for their crops, and less food goes to waste.

This isn't just about technology but about connecting the dots between energy efficiency, public health, and economic opportunity.

Rwanda's progress in sustainable cooling could become a model for other African nations facing similar challenges, turning local solutions into continental impact.
