6.1 Geography, Natural Resources & Administrative Regions of Ghana

Ghana is situated in West Africa along the Gulf of Guinea, spanning an expansive territorial area of approximately 238,535 square kilometers (92,099 square miles). Geographically positioned between latitudes 4°44'N and 11°11'N, and longitudes 3°11'W and 1°11'E, Ghana sits just north of the Equator. Notably, the Prime Meridian (Greenwich Meridian, 0° longitude) traverses the country directly through the industrial port city of Tema, establishing Ghana as one of the few sovereign nations closest to the geographic center of the world where the Equator and Prime Meridian intersect. The national topography is predominantly undulating, featuring coastal plains, dissected forest plateaus such as the Kwahu Plateau, the interior Volta Basin, and the Akwapim-Togo mountain ranges along the eastern frontier, culminating in Mount Afadjato (Afadja), Ghana's highest elevation at approximately 885 meters (2,904 feet) above sea level.

International Terrestrial Borders & Strategic Frontiers

Ghana shares approximately 2,420 kilometers of land boundaries with three sovereign Francophone neighbors, bounded to the south by a 539-kilometer coastline along the Atlantic Ocean:

• Western Border (Côte d'Ivoire): Extending approximately 720 kilometers from the northern tripoint with Burkina Faso down to the Atlantic Ocean at Half Assini. Principal border transit checkpoints include Elubo, Dormaa Ahenkro, and Sampa. This frontier is vital for overland commerce and bilateral security cooperation.
• Northern Border (Burkina Faso): Spanning approximately 602 kilometers across the semi-arid interior savannah from the Black Volta River in the west to the eastern frontier near Bawku. Major border crossings include Paga and Kulungugu, serving as crucial arterial corridors for landlocked Sahelian trade.
• Eastern Border (Togo): Stretching roughly 1,098 kilometers from the northern tripoint southwards to the coastal terminal of Aflao, which borders Togo's capital, Lomé. The Aflao border post represents one of the busiest cross-border commercial and passenger hubs in West Africa.
• Southern Maritime Border (Gulf of Guinea): Ghana commands an Exclusive Economic Zone (EEZ) extending 200 nautical miles seaward into the Gulf of Guinea. This maritime domain holds vital strategic significance for commercial shipping lanes, rich fisheries, offshore hydrocarbon installations, and coastal defense patrols coordinated by the Ghana Navy.

The 16 Administrative Regions & Regional Capitals

From 1983, when the Upper Region was split into Upper East and Upper West, until 2019, Ghana was divided into 10 administrative regions. In response to long-standing petitions from traditional councils, local leaders, and civic groups seeking decentralized governance, enhanced administrative efficiency, and equitable distribution of public resources, the government established the Justice Stephen Alan Brobbey Commission of Inquiry in 2017. Following extensive public hearings and field evaluations, the commission recommended the creation of six new administrative regions.

On 27 December 2018, a historic constitutional referendum was held in the affected territories under Constitutional Instruments CI 112 through CI 117. With overwhelming voter turnout and approval rates exceeding 98 percent, the six new regions were formally promulgated and inaugurated in February 2019, bringing the total number of administrative regions in Ghana to 16:

1. Western North Region — Carved from the northern portion of the Western Region, with its regional capital at Sefwi Wiawso.
2. Bono East Region — Carved from the eastern sector of the former Brong-Ahafo Region, with its regional capital at Techiman.
3. Ahafo Region — Carved from the southern belt of the former Brong-Ahafo Region, with its regional capital at Goaso (while the remaining western portion of the territory became the Bono Region, retaining Sunyani as its capital).
4. Savannah Region — Carved from the western territory of the Northern Region, with its regional capital at Damongo. Spanning roughly 35,862 square kilometers, Savannah is Ghana's largest administrative region by land area.
5. North East Region — Carved from the northeastern sector of the Northern Region, with its regional capital at Nalerigu.
6. Oti Region — Carved from the northern sector of the Volta Region, with its regional capital at Dambai.

Comprehensive Regional Breakdown

Hydrographic Network & Major Water Bodies

Ghana's drainage system is organized into three major river basins: the Volta River Basin, which drains over 70 percent of the nation's total land area; the Southwestern River Basin; and the Coastal River Basin.

Lake Volta & Hydroelectric Dams

Lake Volta is the largest artificial reservoir in the world by surface area, covering approximately 8,502 square kilometers (3,283 square miles) with a storage capacity of roughly 148 cubic kilometers of water. Created between 1961 and 1965 through the construction of the Akosombo Dam across the Volta River gorge, the lake stretches about 400 kilometers north from the dam at Akosombo. The project, conceived under the presidency of Dr. Kwame Nkrumah and managed by the Volta River Authority (VRA), provides vital base-load hydroelectric power for domestic consumption and industrial smelting. In 1982, the Kpong Dam was commissioned downstream at Akuse to generate additional hydroelectric energy. Beyond electricity, Lake Volta serves as an inland marine transit corridor connecting southern ports with northern depots at Buipe, while supporting extensive commercial inland freshwater fisheries.

Major River Networks

• The Volta Basin Rivers: Fed by three principal northern tributaries—the Black Volta (which originates in Burkina Faso and powers the 400 MW Bui Hydroelectric Dam), the White Volta (which enters from Burkina Faso and flows south through northern Ghana), and the Red Volta—alongside the Oti River, which enters from Togo to empty directly into Lake Volta.
• The Southwestern Forest Rivers: Flowing southward through rich rainforests into the Gulf of Guinea. The Pra River is the largest of the southwestern systems, with major tributaries including the Offin, Birim, and Anum rivers, discharging into the ocean at Shama. The Ankobra River drains the mineral belts of Prestea and Tarkwa, reaching the sea at Sanwoma. The Tano River flows along the western frontier into the Aby Lagoon in Côte d'Ivoire.
• Coastal Basin Rivers: Smaller independent coastal rivers, notably the Densu River, which rises in the Atewa Range and is impounded by the Weija Dam in Greater Accra to deliver potable water to metropolitan Accra, and the Ayensu River.

Lake Bosumtwi

Located approximately 30 kilometers southeast of Kumasi in the Ashanti Region, Lake Bosumtwi is Ghana's sole natural inland lake. The lake occupies an ancient meteorite impact crater formed roughly 1.07 million years ago during the Pleistocene epoch. With a diameter of roughly 8 kilometers, a circular circumference, and depths exceeding 70 meters, Lake Bosumtwi has no surface outlet, receiving water exclusively through internal rainfall runoff. It holds profound sacred and cultural significance in Ashanti tradition, where souls of the departed are believed to gather to commune with the deity Twi.

Coastal Lagoons

Numerous lagoons line the Atlantic coastline, serving as critical ecological zones and economic resources. The Keta Lagoon in the Volta Region is Ghana's largest natural coastal lagoon, recognized as an internationally significant Ramsar wetland habitat for migratory waterfowl. The Songor Lagoon in the Greater Accra Region serves as a prime center for commercial and artisanal sea salt production, while the Korle and Sakumo lagoons border urban centers in Accra and Tema.

Natural Resources & Economic Foundations

Ghana's economic resilience is anchored by an abundant endowment of natural mineral deposits, energy resources, and agricultural commodities:

• Gold: Earning the country its historic pre-independence name "Gold Coast," gold remains Ghana's foremost mineral export. Ghana is recognized as Africa's leading gold producer, surpassing South Africa. Industrial production centers on world-class operations in Obuasi (AngloGold Ashanti), Tarkwa (Gold Fields), Ahafo (Newmont), and Akyem (owned by Zijin Mining since April 2025), complemented by extensive mechanized and artisanal operations across the Birimian rock formations.
• Crude Oil & Natural Gas: Commercial offshore hydrocarbon production began in December 2010 with the commissioning of the Jubilee Field in the deepwater Tano Basin off Cape Three Points in the Western Region. Hydrocarbon output expanded with the development of the TEN (Tweneboa, Enyenra, and Ntomme) fields in 2016 and the Sankofa-Gye Nyame fields. Gas from the Jubilee and TEN fields is piped to the Atuabo Gas Processing Plant in the Western Region, while gas from the Sankofa-Gye Nyame fields comes ashore at the Sanzule onshore receiving facility; both supply thermal power stations such as those at Aboadze.
• Cocoa: Ghana is the world's second-largest producer of premium cocoa beans. Introduced in 1879 by Tetteh Quarshie, who brought Amelonado pods from Fernando Po (Bioko Island) to establish an initial farm at Mampong-Akwapim, cocoa serves as the backbone of the rural agricultural economy. Production is supervised by the state regulatory body, the Ghana Cocoa Board (COCOBOD), across the Western North, Western, Ashanti, Eastern, Central, and Ahafo regions.
• Timber: Tropical hardwood species such as Odum, Mahogany, Sapele, and Wawa are harvested under sustainable forestry concessions across the southwestern deciduous and evergreen rainforests.
• Industrial Minerals: Bauxite is actively mined at Awaso in the Western North Region by the Ghana Bauxite Company; Manganese is extracted at Nsuta near Tarkwa in the Western Region; Alluvial diamonds have historically been recovered from gravel beds along the Birim River basin at Akwatia; and commercial lithium reserves have been discovered at Ewoyaa in the Central Region, positioning Ghana as a future contributor to global clean energy supply chains.
