Geography

Ghana is located on the Gulf of Guinea, a few degrees north of the Equator. It spans an area of 239,567 km (92,497 sq mi) and has an Atlantic coastline that stretches 560 kilometres (350 miles) on the Gulf of Guinea in the Atlantic Ocean to its south. Dodi Island and Bobowasi Island are near the south coast. It lies between latitudes 4°45'N and 11°N, and longitudes 1°15'E and 3°15'W. The prime meridian passes through Ghana, specifically through Tema. Ghana is geographically closer to the intersection of the Prime Meridian and the Equator than any other country, since this point, (0°, 0°), is located in the Atlantic Ocean approximately 614 km (382 mi) off the south-east coast of Ghana.

Grasslands mixed with south coastal shrublands and forests dominate Ghana, with forest extending northward from the coast 320 kilometres (200 miles) and eastward for a maximum of about 270 kilometres (170 miles) with locations for mining of industrial minerals and timber. Ghana is home to five terrestrial ecoregions: Eastern Guinean forests, Guinean forest–savanna mosaic, West Sudanian savanna, Central African mangroves, and Guinean mangroves. It had a 2018 Forest Landscape Integrity Index mean score of 4.53/10, ranking it 112th globally out of 172 countries.

The White Volta River and its tributary Black Volta, flow south through Ghana to Lake Volta, the world's third-largest reservoir by volume and largest by surface area, formed by the hydroelectric Akosombo Dam, completed in 1965. The Volta flows out of Lake Volta into the Gulf of Guinea. The northernmost part of Ghana is Pulmakong and the southernmost part of Ghana is Cape Three Points.

The climate of Ghana is tropical, and there is wet season and dry season. Ghana sits at the intersection of three hydro-climatic zones. Changes in rainfall, weather conditions and sea-level rise affect the salinity of coastal waters. This is expected to negatively affect both farming and fisheries.

In 2015, the government produced a document titled "Ghana's Intended Nationally Determined Contribution". Following that, Ghana signed the Paris Climate Agreement in 2016.
