GMet warns of possible drop in Volta River inflows amid El Niño conditions

The Ghana Meteorological Agency (GMet) has cautioned that ongoing El Niño conditions may lead to a decrease in water inflows into the Volta River, which could impact hydroelectric power generation at the Akosombo Dam. El Niño, a natural climate event, affects rainfall and temperature patterns globally. Francisca Martey, Deputy Director of Research and Applied Meteorology at GMet, stated that below-normal rainfall anticipated in West Africa could impact water resources shared by Ghana and neighboring countries.

This phenomenon has influenced rainfall patterns, causing prolonged dry spells and warmer conditions in parts of Ghana. These impacts extend beyond Ghana's borders, with neighboring countries in the wider West African region also expected to face below-normal rainfall. Martey emphasized that reduced rainfall would lead to lower inflows into the Akosombo Dam, consequently affecting electricity generation from hydroelectric sources.

The agency has projected above-normal temperatures and below-normal rainfall in the coming months, with extended dry spells forecasted from September to November (SON) and into the December-January-February (DJF) period. Northern Ghana is particularly vulnerable due to its susceptibility to rainfall deficits and its critical role in the country's food production.

Prolonged dry conditions could adversely affect farmers, especially those relying on stored rainwater for agricultural activities. Martey advised farmers to adopt climate-smart agricultural practices, such as mulching, to conserve soil moisture and mitigate the impacts of prolonged dry spells. GMet is collaborating with stakeholders in agriculture, health, water resources management, and the public to enhance preparedness for the anticipated weather conditions.

Ghanaians are urged to stay hydrated and protect themselves against the dusty conditions expected during the Harmattan season.
