In southwestern Ghana, a patchwork of tropical forest lies among widespread farmland dotted with towns. These forest fragments are remnants of the Upper Guinean forest of West Africa, a biodiversity hotspot that has been diminished by human activity and fires.
Primates, elephants, hippopotamuses, and butterflies are among the thousands of animals that live in the region’s primary forests, which are almost entirely within a network of forest reserves. But satellite images indicate that these protected forest remnants have become even smaller in recent decades.
The false-colour images above, acquired by the Landsat 4 and Landsat 9 satellites, show 12 protected forest reserves and Bia National Park in the Bia-Goaso forest district in 1989 (left) and 2023 (right). The forested canopies of the reserves are dark green, whereas the surrounding landscape is lighter green.
“This area has historically been an important forest habitat for biodiversity, but elephant populations have declined precipitously because of human encroachment and habitat degradation,” said Michael Wimberly, a professor of geography and environmental sustainability at the University of Oklahoma. The photograph below, taken by Wimberly, shows intact forests in a reserve east of the Bia-Goaso region.
Wimberly and a team of researchers in the United States and Ghana used Landsat data to study forest degradation, loss, and recovery in the reserves across Ghana from 2003 to 2019. Although vegetation change was relatively slow from 2003 to 2015, it picked up significantly between 2015 and 2019.
Overall, there was more forest loss and degradation than recovery, resulting in a gradual decline of tree cover.
The drivers of change here are multifaceted, noted Wimberly. In 2016, drought associated with El Niño parched forests and promoted fires across more than 12 percent of Ghana’s moist semi-deciduous and upland evergreen forests. Forest loss was especially prevalent in a reserve known as Bonsam Bepo, south of the city of Goaso.
In a reserve southeast of this image, mining operations contributed to forest loss. In the reserve north of Bia National Forest, widespread logging for timber from 2017 to 2019 led to forest degradation. In other reserves, such as Krokosua (the u-shaped reserve at the bottom of the image), the expansion of cocoa farms has consumed forest. Ghana and neighbouring Côte D’Ivoire produce about two-thirds of the world’s cocoa.
A 2024 United Nations report on the state of the world’s forests highlighted the Forest Data Partnership, an effort to help people in Ghana access remote sensing data to track commodities linked to deforestation and prevent forest loss.
The approach is being field-tested in Ghana and at the joint NASA-USAID SERVIR program’s regional hub for West Africa to help make agricultural production and food systems more sustainable.
Wimberly and colleagues continue to monitor Ghana’s tropical forest landscapes and forest reserves using Landsat data and models to classify the health of forests. Their updated results can be explored in this interactive map.

The 29th Annual Dagaaba-Frafra Friendly Games have once again demonstrated that sports can be a powerful vehicle for cultural preservation, business networking, friendship and peaceful coexistence.
Held at the El-Wak Sports Stadium in Accra last Saturday, the games brought together members of the two ethnic groups from across Ghana and abroad for a colourful celebration under the theme, “Unity in Diversity: The Dagaaba-Frafra Model for Peaceful Co-existence.”
The event, which has evolved from a friendly football match into a major annual gathering, featured football, volleyball, sack races, lime and spoon, tug-of-peace and a penalty shootout for senior citizens.
At the end of the competitions, the Frafra won four events, while the Dagaaba secured victories in five, with the men’s soccer match ending in a draw.
The Frafra triumphed in the men’s lime and spoon, men’s sack race, women’s sack race and women’s soccer, while the Dagaaba won the women’s lime and spoon, men’s volleyball, women’s volleyball, women’s tug-of-peace and the senior citizens’ penalty shootout.
However, the games extended far beyond the sporting arena. The stadium grounds and surrounding spaces became a vibrant marketplace, with patrons enjoying and purchasing a variety of traditional foods, drinks and cultural products.
Local delicacies, including TZ, tubaani, bambara beans, pork, guinea fowl, local fowls, dog meat and kosie, were sold alongside traditional alcoholic beverages. Traditional dresses and other culturally inspired items also attracted buyers, turning the gathering into an important platform for small businesses and vendors to make sales while promoting northern Ghanaian culture.
The cultural exchange continued long after the final sporting contests, as patrons remained at the venue to eat, drink, socialise, dance and party well into the night.
In her remarks, the Guest of Honour, Dr Matilda Aberese-Ako, said the gathering represented much more than competition, describing the Dagaaba-Frafra relationship as a historic bond that had evolved into a modern sporting tradition and an instrument for peace.
MTN Ghana has been the headline sponsor for the games for the past 10 years.

MTN Ghana has undertaken a tree-planting exercise at the Chipa Forest Reserve as part of its commitment to protecting the planet and support the restoration of degraded sections of the forest.
The activity forms part of the company’s 2026 Sustainability Month celebration held under the theme “Small Actions: Big Impact,” and its 30th anniversary celebration.
It was held in partnership with the Forestry Commission (FC) and the Rainforest Alliance with MTN Ghana supporting the restoration of approximately two hectares of degraded forest through the planting of 1,666 trees.
Due to the current dry weather conditions, 833 trees were planted during the exercise, with the remaining 833 to be planted when the rain commences.
The exercise brought together MTN employee volunteers, officials from the Forestry Commission and representatives of the Rainforest Alliance, demonstrating the importance of collaboration in driving environmental sustainability.
Speaking at the event, the Acting General Manager for Sustainability and Shared Value at MTN Ghana, Georgina Asare Fiagbenu, emphasized the critical role trees play in sustaining life and protecting the environment.
“Trees are essential to human survival and healthy ecosystems. They absorb carbon dioxide, release oxygen, regulate temperatures, protect soil, support biodiversity and provide habitats for many species. They also conserve water, reduce erosion and help communities adapt to the effects of climate change,” she said.
The District Manager of the Tema-Ada Forest Services Division of the Forestry Commission, Linda Ansah, welcomed MTN Ghana’s support, describing it as a valuable contribution to efforts aimed at restoring degraded sections of the reserve.
The Country Director of the Rainforest Alliance, Nicholas Jengri, also welcomed the partnership and emphasised the importance of collective action in addressing environmental challenges.
