context_page_description: Benin, officially the Republic of Benin and formerly known as Dahomey, is a country in West Africa. It is bordered by Togo to the west, Nigeria to the east, Burkina Faso to the north-west, and Niger to the north-east. The majority of its population lives on the small southern coastline of the Bight of Benin, part of the Gulf of Guinea in the northernmost tropical portion of the Atlantic Ocean. The capital of Benin is Porto-Novo, but the seat of government is in Cotonou, the country's largest city and economic capital. Benin covers an area of 114,763 square kilometres and its population in 2018 was estimated to be approximately 11.49 million. Benin is a tropical nation, highly dependent on agriculture, and is a large exporter of cotton and palm oil. Substantial employment and income arise from subsistence farming.
  The official language of Benin is French, with several indigenous languages such as Fon, Bariba, Yoruba and Dendi also being commonly spoken. The largest religious group in Benin is Roman Catholicism, followed closely by Islam, Vodun and Protestantism.
context_section_description: Benin, a narrow, north–south strip of land in West Africa, lies between latitudes 6° and 13°N, and longitudes 0° and 4°E. Benin is bounded by Togo to the west, Burkina Faso and Niger to the north, Nigeria to the east, and the Bight of Benin to the south. The distance from the Niger River in the north to the Atlantic Ocean in the south is about 650 km (404 mi). Although the coastline measures 121 km (75 mi), the country measures about 325 km (202 mi) at its widest point.
  Benin shows little variation in elevation and can be divided into four areas from the south to the north, starting with the low-lying, sandy, coastal plain (highest elevation 10 m (32.8 ft)) which is, at most, 10 km (6.2 mi) wide. It is marshy and dotted with lakes and lagoons communicating with the ocean. Behind the coast lies the Guinean forest-savanna mosaic-covered plateaus of southern Benin (altitude between 20 and 200 m (66 and 656 ft)), which are split by valleys running north to south along the Couffo, Zou, and Ouémé Rivers.
  This geography makes it vulnerable to climate change. With the majority of the country living near the coast in low-lying areas sea level rise could have large effects on the economy and population. Northern areas will see additional regions become deserts, making agriculture difficult in a region with many subsistence farmers.
  An area of flat land dotted with rocky hills whose altitude seldom reaches 400 m (1,312 ft) extends around Nikki and Save.
  A range of mountains extends along the northwest border and into Togo; these are the Atacora. The highest point, Mont Sokbaro, is at 658 m (2,159 ft). Benin has fallow fields, mangroves, and remnants of large sacred forests. In the rest of the country, the savanna is covered with thorny scrub and dotted with huge baobab trees. Some forests line the banks of rivers. In the north and the northwest of Benin, the Reserve du W du Niger and Pendjari National Park attract tourists eager to see elephants, lions, antelopes, hippos, and monkeys. Pendjari National Park together with the bordering Parks Arli and W in Burkina Faso and Niger are among the most important strongholds for the endangered West African lion. With an estimated 356 (range: 246–466) lions, W-Arli-Pendjari harbors the largest remaining population of lions in West Africa. Historically Benin has served as habitat for the endangered painted hunting dog, Lycaon pictus; however, this canid is thought to have been locally extirpated.
  Benin's climate is hot and humid. Annual rainfall in the coastal area averages 1300 mm or about 51 inches. Benin has two rainy and two dry seasons per year. The principal rainy season is from April to late July, with a shorter less intense rainy period from late September to November. The main dry season is from December to April, with a short cooler dry season from late July to early September. Temperatures and humidity are high along the tropical coast. In Cotonou, the average maximum temperature is 31 °C (87.8 °F); the minimum is 24 °C (75.2 °F).
  Variations in temperature increase when moving north through savanna and plateau toward the Sahel. A dry wind from the Sahara called the Harmattan blows from December to March, when grass dries up, other vegetation turns reddish brown, and a veil of fine dust hangs over the country, causing the skies to be overcast. It is also the season when farmers burn brush in the fields.
