The United Nations Educational, Scientific and Cultural Organisation (UNESCO) has handed over nine automated weather stations to the Ghana Meteorological Agency (GMet) in a move aimed at strengthening early warning systems and climate resilience, particularly in the country’s flood- and drought-prone northern regions.
The ceremony marked the culmination of a $750,000 project titled “Strengthening Resilience on Water-Related Disasters under Climate Change for a Sustainable Society in Ghana,” funded by the Government of Japan. The equipment will be deployed across the Northern, Savannah, North East, and Upper East Regions, where erratic rainfall, floods, and droughts have repeatedly devastated crops, livelihoods, and infrastructure.
Closing Critical Data Gaps
Northern Ghana is the nation’s food basket, with up to 98 percent of households engaged in farming. Yet the region remains dangerously underserved by meteorological infrastructure. Ideally, every district should have its own weather station, but GMet currently operates only 47 stations across 261 Metropolitan, Municipal, and District Assemblies (MMDAs).
The new sensor-based, self-recording stations will transmit real-time data without manual intervention, replacing outdated methods where staff had to collect and code hourly readings around the clock.
Mr. Edmond Moukala N’Gouemo, UNESCO Representative to Ghana, described the handover as “a significant milestone,” stating: “Accurate, timely and reliable meteorological data is the backbone of effective early warning systems. These weather stations are instruments of anticipation rather than reaction, of prevention rather than response.”
GMet Director-General Dr. Eric Asuman welcomed the support as timely, noting that maintaining meteorological infrastructure remains capital-intensive. “To generate data previously, staff had to man stations for twenty-four hours. These automatic weather stations, which are self-recording and self-transmitting, make data collection more reliable and efficient,” he said.
A Response to Recent Climate Shocks
The project responds directly to escalating climate risks. Madam Matila Akua Afriyie, Disaster Risk Reduction Project Officer at UNESCO’s Accra office, pointed to the 2023 Akosombo Dam spillage and the 2024 drought, which affected approximately one million people, as urgent reminders of Ghana’s vulnerability.
The nine stations will help validate forecasts, refine prediction models, and enable more location-specific warnings. Dr. Ignatius Kweku Williams, Deputy Director-General for Operations at GMet, explained: “Once we put out a forecast, we need observations from the ground to validate what has happened. If we predicted rain for Accra, we need to know which parts received rain and how much. This helps us refine our models.”
A Model for GMet’s Operational Leap Forward?
The deployment of automated weather stations is consistently shown to transform national forecasting agencies from reactive to proactive services.
In Kenya, a similar UNESCO-backed installation of 10 automated stations in 2024 reduced flood response times by nearly 40 percent during the March–May rainy season, according to the Kenya Meteorological Department. In Malawi, automated systems enabled the first-ever district-level maize yield forecasts, directly informing food distribution months before harvest failures materialised.
For GMet, these nine stations represent more than equipment—they are a strategic wedge. The agency has launched an “Adopt a Weather Station” initiative, encouraging private entities, municipal assemblies, and individuals to fund and host additional units. The UNESCO donation proves the viability of automated networks, making it easier to attract further investment.
Moreover, with real-time data flowing from northern Ghana—where climate impacts are most severe—GMet can now issue lead-time warnings for flash floods and agricultural dry spells with unprecedented accuracy. This shifts the agency’s role from passive data collector to active disaster prevention partner for farmers, emergency managers, and health officials.
The biggest challenge remains scale. With 261 districts and only 56 stations after this donation (47 existing plus nine new), coverage remains thin. However, as Dr. Asuman noted, advances in automation ease the operational burden, freeing staff to focus on analysis and outreach rather than manual collection.
For northern Ghana’s farming families—who have watched rains become a gamble—these nine stations cannot stop the climate from changing. But they can ensure that when disaster looms, the warning arrives in time to save crops, livestock, and lives.
