However, its numbers in India plummeted from the 19th century onward; Divyabhanusinh of the Bombay Natural History Society notes that the last three individuals in the wild were killed by Maharaja Ramanuj Pratap Singh of Surguja (a man also noted for holding a record for shooting 1,360 tigers) in 1947. The last confirmed sighting in India was of a cheetah that drowned in a well near Hyderabad in 1957. In Iran there were around 400 cheetahs before World War II, distributed across deserts and steppes to the east and the borderlands with Iraq to the west; the numbers were falling because of a decline in prey. In Iraq, cheetahs were reported from Basra in the 1920s. Conservation efforts in the 1950s stabilised the population, but prey species declined again in the wake of the Iranian Revolution (1979) and the Iran–Iraq War (1980–1988), leading to a significant contraction of the cheetah's historical range in the region. The first survey of cheetah populations in Africa by Norman Myers in 1975 estimated a population of 15,000 individuals throughout Sub-Saharan Africa. The range covered most of eastern and southern Africa, except for the desert region on the western coast of modern-day Angola and Namibia. In the following years, as their natural habitat has been modified dramatically, cheetah populations across the region have become smaller and more fragmented. Present distribution The cheetah occurs mostly in eastern and southern Africa; its presence in Asia is limited to the central deserts of Iran, though there have been unconfirmed reports of sightings in Afghanistan, Iraq and Pakistan in the last few decades. The global population of cheetahs was estimated at nearly 7,100 mature individuals in 2016. The Iranian population appears to have decreased from 60 to 100 individuals in 2007 to 43 in 2016, distributed in three subpopulations over less than in Iran's central plateau. The largest population of nearly 4,000 individuals is sparsely distributed over Angola, Botswana, Mozambique, Namibia, South Africa and Zambia. Another population in Kenya and Tanzania comprises about 1,000 individuals. All other cheetahs occur in small, fragmented groups of less than 100 individuals each. Populations are feared to be declining. Threats The cheetah is threatened by several factors, like habitat loss and fragmentation of populations. Habitat loss is caused mainly by the introduction of commercial land use, such as agriculture and industry. It is further aggravated by ecological degradation, like bush encroachment, which is
