highest in Africa at about 3.5 per cent per annum, doubling every 21 years. Had this growth been maintained, the population would have been 31 million. Instead, as of 2018, it is about 13 million. The discrepancies were believed to be partly caused by death from starvation and disease, and partly due to decreased fertility. The life expectancy has halved, and deaths from politically motivated violence sponsored by the government exceed 200,000 since 1980. The Mugabe government has directly or indirectly caused the deaths of at least three million Zimbabweans in 37 years. According to World Food Programme, over two million people are facing starvation because of the recent droughts the country is going through. In 2018, President Mnangagwa announced that his government would seek to rejoin the Commonwealth, which is as of 2023 conducting a fact-finding mission prior to asking the Secretary-General to issue a recommendation. On 6 September 2019, former president Robert Mugabe died in Singapore, aged 95. Geography Zimbabwe is a landlocked country in southern Africa, lying between latitudes 15° and 23°S, and longitudes 25° and 34°E. It is bordered by South Africa to the south, Botswana to the west and southwest, Zambia to the northwest, and Mozambique to the east and northeast. Its northwest corner is roughly 150 meters from Namibia, nearly forming a four-nation quadripoint. Most of the country is elevated, consisting of a central plateau (high veld) stretching from the southwest northwards with altitudes between 1,000 and 1,600 m. The country's extreme east is mountainous, this area being known as the Eastern Highlands, with Mount Nyangani as the highest point at 2,592 m. The highlands are known for their natural environment, with tourist destinations such as Nyanga, Troutbeck, Chimanimani, Vumba and Chirinda Forest at Mount Selinda. About 20% of the country consists of low-lying areas, (the low veld) under 900m. Victoria Falls, one of the world's largest and most spectacular waterfalls, is located in the country's extreme northwest and is part of the Zambezi river. Geology Over geological time Zimbabwe has experienced two major post-Gondwana erosion cycles (known as African and post-African), and a very subordinate Plio-Pleistocene cycle. Climate Zimbabwe has a subtropical climate with many local variations. The southern areas are known for their heat and aridity, while parts of the central plateau receive frost in winter. The Zambezi valley is known for its extreme heat, and the Eastern Highlands usually experience cool
