NASA highlights Ghana’s declining forest reserves
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 forecourt of the African University of Communications and Business (AUCB) in Accra came alive on Friday with colour, creativity and innovation, as Level 300 students transformed the space into a lively exhibition of ideas.
Under the theme “Building meaningful brands beyond the logo,” the students invited patrons into a world where ordinary products were reimagined through storytelling, design and purpose.
From scented candles to innovative food concepts, each stand told a unique story, one that went beyond aesthetics to capture identity, value and human connection.
For many of the students, the event was more than just an academic exercise; it was a moment to dream out loud.
Guided by their lecturer, Peter Wonders, they explored what it truly means to build a brand in today’s competitive world where trust, consistency and experience matter just as much as logos and slogans.
Chairman of the occasion, Nana Kum Gyata VI, in his remarks said a brand is what people say about you when you are not present.
At the end of the presentations, awards were presented to deserving groups with Vida Nyaneba emerging as the overall best branding student.

The Senior Correctional Centre (SCC) has initiated a lecture session to broaden the horizon of level 400 students at the Social Work Department of the University of Ghana (UG).
The initiative is under the auspices of the Counselling Unit and OIC of the Station, in consultation with the University.
The inaugural lecture delved into education of Social Work students about the role of Ghana Prisons Service and its core mandates, while emphasising the need for counseling as a psychological intervention for inmates mental health and well-being.
It also gave clearer insights about what was required of them in contributing their quota to creating awareness about the Service’s reformational agenda.
The session forms part of the ‘Think Prisons 360 degrees’ initiative, a collaborative efforts of the SCC Counseling Unit to conscientise the final year students of their roles as future social workers.
ASP Alfred Nii Arday Ankrah, a Public Relation Personnel highlighted on the core roles of the Service which include the welfare of inmates, safe custody of inmates, reformation and rehabilitation of inmates, respectively.
Discussing the ‘Think Prisons 360 degree’ agenda birthed by the Director General of the service, DGP Patience Baffoe-Bonnie Esq, Mr Ankrah enumerated the five core pillars of the initiative which include welfare of inmates and staff, agriculture mechanisation, industrialisation, wealth creation and strategic relations.
DSP Belinda Adjei-Attah, Head of SCC Counselling Unit schooled the final year students about the role of counseling as a pivotal reformational tool in the service with the tendency to enhance inmates’ psychological needs.
DSP Adjei-Attah further highlighted how Prison Officers and social workers could work together to reduce recidivism.
DSP Eugene Ansu Ohene-Tutu, a Counseling Personnel at SCC further elaborated on the role of social workers in aiding psychosocial interventions, expanding support systems and bringing in-house psychiatrists to help circumnavigate inmates’ mental health.
Dr Abena Oforiwa Ampomah, Lecturer at the Department commended the Senior Officers for their time with the final year students and commended the Officer-In-Charge of SCC, DDP Yayra Ashong Mettle, for releasing the officers to make such a memorable lecture.
