2. Basic Information - Ghana Land Area 238,539 km2 Water bodies 3,275 km2 Coastline 539 km Total population 28.3 million (2016) Population growth rate 2.1 % Currency: Ghana cedis (1 USD = 4.2 Ghc) GDP (current prices) US$ 42,676 million (in 2016) GDP per capita US$ 1,507 (2016) Natural resources: Gold, Diamond, oil

3. Sustainable Development Background Climate There are 5 main agro-ecological zones: These are Rain Forest, Deciduous Forest, Transitional Zone, Coastal Savanna and Northern Savanna (Guinea and Sudan Savanna). Rainfall Highest in South-western (2,000 mm/yr), north (950 mm/yr) and south-eastern (800 mm/yr).

4. Sustainable Development background Topography The topography is predominantly undulating, with slopes less than 1%. Even though the slopes are gentle, about 70% of the country is subject to moderate to severe sheet and gully erosion. Temperature Average maximum temperatures are highest between February to April (320 C) in the southern zone whiles that for the northern zone occurs from April to May (340C).

5. Land use Settlements land cover class. From 1,460 sq km in 1975, urban areas expanded to 3,830 sq km in 2013 representing 161% increase over 38 years. Agricultural land use increased from 13% of Ghana total area 1975 to 32% 2013. Savannas experienced a large loss, from about 51 to 40 percent of the total land area from 1975 to 2013 The forest class (represented primarily by Ghana s dense evergreen rain forest and moist deciduous forest) shows a small decline in area from about 16,400 sq km in 1975 to 12,400 sq km in 2013

6. Water Availability and use Surface water resources Volta system: four main rivers (Red, white, black and Oti) make up 70% of surface water resources. South-Western system: (Bia, tano, ankobra and pra) make up 22% of surface water resources. Coastal system: (Tordzie, Aka, Densu, Ayensu, Ochi-Nakwa and Ochi-Amissah) make up 8% of surface water resources.

Coverage rate is 76% in 2015
