Sub-Saharan Africa has not been as badly hit by the coronavirus pandemic as some other parts of the world, but the economy is being pummelled.Here's a look at the main issues.Perfect storm recessionFor the first time in 25 years sub-Saharan Africa is about to go into recession, according to World Bank estimates.Following 2.4% growth last year, the estimate for 2020 is between -2.1% and -5.1% as the economy contracts.This is in part a knock-on effect from the economic hits being taken by Africa's main trading partners: China, the EU and the United States.Add to that the slump in the key markets of raw materials and tourism as well as the effect of measures to confine populations at home and you have the perfect economic storm for the continent.The African Development Bank remains less pessimistic but still sees a fall into recession of between -0.7% and -2.8%.Tens of millions of jobs in dangerThe African Union estimates that around 20 million jobs, in formal and informal sectors, are under threat.The United Nations puts the figure much higher, at up to 50 million.Money transfers from diaspora dropHigh unemployment and economic slowdown are also hitting African workers abroad, and therefore their money transfers back home, which are often a vital part of the economy.The transfers to Mali in 2018 represented 5.5%, according to Bloomfield Investment analysts.The figure for Senegal was 10%.These cash transfers are expected to fall significantly with more than half the world's population in some kind of lockdown.Price of raw materials plummetsSub-Saharan Africa's two biggest economies, South Africa and Nigeria are heading for deep recessions, according to the World Bank, as demand drops from developed nations for raw materials such as oil and precious metals.The same goes for Angola, Africa's second biggest oil exporter.Oil prices have fallen to between $20 and $30 a barrel, nearing the cost of production in Nigeria.Coronavirus: Spain, Denmark, Italy and Austria are lifting their restrictions | @BISouthAfrica https://t.co/QJlBK7NOVm pic.twitter.com/94Usg54G6a— News24 (@News24) April 14, 2020 Even gold, a traditional safe haven for investors, is not immune. The reduction in air transport and the closure of some refineries is limiting gold exports, according to Bloomfield Investment.And the cotton market is down sharply, a matter highlighted on Friday by President Ibrahim Boubacar Keta of Mali, where around a quarter of the workforce is linked to the sector.Tourism and air traffic downSub-Saharan Africa's important tourism sector is practically non-existent under the current bans on travel.South Africa, the biggest draw on the continent for holiday-makers, has already been negatively impacted and that is set to continue, warned tourism ministry spokesperson Hlengiwe Nhlabathi. Tourism contributes to 1.5 million jobs in the country.The crisis in the sector will have wider repercussions, affecting "agriculture, fisheries, banks, insurance, transport, culture and entertainment", she added."We've stopped everything because there are no clients. We have had to let two thirds of our employees go, that's 20 people,' said Sidiki Dramane Konate who runs Le Bambou hotel in Burkina Faso.The African Airlines Association warns that with 95% of flights grounded carriers are in danger of folding without financial aid.Coffee and cocoa markets threatenedIn Ethiopia, Africa's largest coffee producer, exporters are already experiencing a "devastating shock", according to Gizat Worku, head of the country's Coffee Exporters Association.International Covid-19 update: More than 120 000 killed by coronavirus worldwide, China approves trials for more vaccines, deaths in Sweden pass 1 000 | #CoronavirusPandemichttps://t.co/EthjpE85V6 pic.twitter.com/F3wfiPYO0R— News24 (@News24) April 14, 2020 Business from the main importers in Europe and the US is at a standstill.Coffee brings in five percent of the country's GDP and directly employs 25 million people, out of a population of 110 million.In the short term the crisis is unlikely to have a major impact on the cocoa market, according to the Michel Arrion, head of the International Cocoa Organisation, because the main importers have around 1.8 million tonnes of stock, equal to four or five months production.But "there is a real fear among planters of a long-term drop in prices," said Moussa Kone, president of the growers union in Ivory Coast which produces 40 percent of the world market in "brown gold" and employs up to six million people.Stemming the crisisSeveral African nations have announced economic and social support plans.But with less than 20% of the population formally employed, with social security systems non-existent in the informal sector and with national coffers in a poor state before even before the current crisis, "the situation is particularly critical for Africa", according to the Finactu accountancy firm which operates in 30 African countries.It will take some kind of African "Marshall Plan" from the international community and a significant debt write-off to get Africa back on its feet, says Niger's President Mahamadou Issoufou.
