| • Other | 98.08% |

Narrow coastal plain with patches of Central African mangroves; hilly interior; savanna in east and south. A recent global remote sensing analysis suggested that there were 420 km2 of tidal flats in Gabon, making it the 50th ranked country in terms of tidal flat area.[1]
- Irrigated land: 44.5 km2 (2003)
- Total renewable water resources: 164 km3 (2011)

Climate
[edit]The equatorial location of Gabon means that it has a tropical monsoon climate (Köppen Am) and a tropical savanna climate (Köppen Aw), with the temperature being hot year-round and humid, although the Benguela Current can moderate temperatures.

Climate change
[edit]Gabon is highly vulnerable to climate change due to its dense coastal population, economic hubs along the shore, and dependence on rain-fed agriculture.[8] Rising sea levels threaten to erode the coastline and contaminate freshwater sources with saltwater. The country is already experiencing more frequent and severe extreme weather events, such as floods, droughts, and storms, which damage infrastructure, displace communities, and disrupt food security and livelihoods.[9]
To adapt, Gabon prioritises protecting its coastal areas, as well as its fishing, agriculture, and forestry industries.[8] Gabon's vast forests act as a net carbon sink.[10][11] It is recognized as a global leader in climate action and is widely considered the most carbon-positive country in the world, due to its strong conservation efforts.[9] However, Gabon’s economy remains heavily dependent on oil and other natural resources, leaving it exposed to global market shifts and climate-related risks. In 2023, the country accounted for just over 0.04% of global greenhouse gas emissions (24.7 million tonnes). Gabon has pledged to stay carbon neutral beyond 2050 and, with adequate support, aims to maintain net carbon removals of 100 million tons CO2 equivalent per year beyond that date.[12] It also seeks to expand its renewable energy sector.[13]
Extreme points
[edit]- Northernmost point - unnamed location on the border with Cameroon on the Ntem River, Woleu-Ntem province
- Easternmost point - the unnamed location on the border with the Republic of Congo immediately south-west of the Congolese village of Mbeyi-Mbola, Haut-Ogooué province
- Southernmost point - the point at which the border with the Republic of Congo enters the Atlantic Ocean, Nyanga Province
- Westernmost point - the north-west point of Cape Lopez, Ogooué Maritime province

View on GrokipediaLocation and Extent
Area and Borders
Gabon has a total area of 267,667 square kilometers, comprising 257,667 square kilometers of land and 10,000 square kilometers of inland water bodies. This makes it slightly larger than the U.S. state of Colorado. The country's territory is situated in Central Africa, straddling the equator, with its land area characterized by dense equatorial forests covering approximately 85% of the surface. Gabon shares land borders with three neighboring countries, totaling 3,261 kilometers in length. To the northwest, it borders Equatorial Guinea for 345 kilometers; to the north, Cameroon for 349 kilometers; and to the east and south, the Republic of the Congo for 2,567 kilometers, which constitutes the majority of its international boundaries. These borders are largely defined by natural features such as rivers and forested regions, though precise demarcations have occasionally been subject to minor disputes, particularly along the Cameroon frontier, resolved through bilateral agreements in the early 2000s.| Neighboring Country | Border Length (km) |
|---|---|
| Equatorial Guinea | 345 |
| Cameroon | 349 |
| Republic of the Congo | 2,567 |
