Chad is a landlocked country at the crossroads of North and Central Africa. It is bordered by Libya to the north, Sudan to the east, the Central African Republic to the south, Cameroon to the south-west, Nigeria to the southwest, and Niger to the west. Chad has a population of 16 million.
Chad's animal and plant life correspond to the three climatic zones. In the Saharan region, the only flora is the date-palm groves of the oasis. Palms and acacia trees grow in the Sahelian region. The southern, or Sudanic, zone consists of broad grasslands or prairies suitable for grazing. As of 2002, there were at least 134 species of mammals, 509 species of birds, and over 1,600 species of plants throughout the country.
Elephants, lions, buffalo, hippopotamuses, rhinoceroses, giraffes, antelopes, leopards, cheetahs, hyenas, and many species of snakes are found here, although most large carnivore populations have been drastically reduced since the early 20th century. Elephant poaching, particularly in the south of the country in areas such as Zakouma National Park, is a severe problem. The small group of surviving West African crocodiles in the Ennedi Plateau represents one of the last colonies known in the Sahara today.
Chad had a 2018 Forest Landscape Integrity Index mean score of 6.18/10, ranking it 83rd globally out of 172 countries. Extensive deforestation has resulted in loss of trees such as acacias, baobab, dates and palm trees. This has also caused loss of natural habitat for wild animals; one of the main reasons for this is also hunting and livestock farming by increasing human settlements. Populations of animals like lions, leopards and rhino have fallen significantly.
Efforts have been made by the Food and Agriculture Organization to improve relations between farmers, agro-pastoralists and pastoralists in the Zakouma National Park, Siniaka-Minia, and Aouk reserve in southeastern Chad to promote sustainable development. As part of the national conservation effort, more than 1.2 million trees have been replanted to check the advancement of the desert, which incidentally also helps the local economy by way of financial return from acacia trees, which produce gum arabic, and also from fruit trees.
Poaching is a serious problem in the country, particularly of elephants for the profitable ivory industry and a threat to lives of rangers even in the national parks such as Zakouma. Elephants are often massacred in herds in and around the parks by organized poaching. The problem is worsened by the fact that the parks are understaffed and that a number of wardens have been murdered by poachers.
