As people around the globe eye Africa for potential investment and South Africans head north there is some encouraging news to feed those aspirations, worried reports to temper our enthusiasm and some mistakes to learn from.

Ghana's capital Accra is awash with educated, well-dressed young up-and-coming people, driving top-of-the-range cars living in stylish homes. It's indicative of Ghana's economic growth, 14.4% last year. According to the World Bank many African economies are forecast to be among the world's fastest growing in 2012. Top of that list are the DRC, Nigeria, Ghana, Liberia and Ethiopia.

US-based business consulting company Ernst & Young reports: "There is a new story emerging out of Africa: a story of growth, progress, potential and profitability." US secretary of state for African affairs, Johnnie Carson is quoted as saying that Africa represents the next global economic frontier. China's trade with Africa reached $ 160 billion in 2011, making the contributor one of its largest trading partners.

London based magazine The Economist reported last month: "Since The Economist regretably labeled Africa 'the hopeless continent' a decade ago, a substantial change has taken hold." Today "the sun shines bright … the continent's impressive growth looks likely to continue."

Africa's trade with the rest of the globe has skyrocketed by more than 200% and annual inflation has averaged only 8%. Foreign debt has dropped by 25% and foreign direct investment (FDI) grew by 27% in 2011 alone.

Despite projections for growth in 2012 being revised downward due to the so called Arab Spring, Africa's economy is expected to expand by 4.2%, according to a UN report earlier in the year. The International Monetary Fund (IMF) is expecting Sub-Saharan African economies to increase at above 5%. Added to that, there are currently more than half a billion mobile phone users in Africa, while improving skills and increasing literacy are attributed to a 3% growth in productivity.

According to a UN report the think tank, McKinsey Global Institute writes, "The rate of return on foreign investment is higher in Africa than in any other developing region."

An end to numerous military conflicts, the availability of abundant natural resources and economic reforms have promoted a better business climate and helped propel Africa's economic growth. Greater political stability is increasing the continent's economic engine. The UN Economic Commission for Africa (ECA) in 2005 linked democracy to economic growth.

All this growth and urbanization is putting a strain on social services in the cities, it has also led to an increase in urban consumers. More than 40% of Africa's population now lives in cities, and by 2030 Africa's top 18 cities will have a combined spending power of $ 1.3 trillion. The Wall Street Journal reports that Africa's middle class, currently estimated at 60 million, will reach 100 million by 2015.

Then there's the more sobering news. "A sustained slowdown in advanced countries will dampen demand for Africa's exports," writes Christine Lagarde, managing director of the IMF. Europe accounts for more than half of Africa's external trade. Tourism could also suffer as fewer Europe come to Africa, effecting tourist dependent economics like Kenya, Tanzania and Egypt.

The South African Reserve bank warned in May that the financial crisis in Europe, which consumes 25% of South Africa's exports, poses large risks. Adverse effects on South Africa could have severe consequences for neighboring economies.

Another worry is the resurgence of political crises. Due to the so called Arab Spring, economic growth in North Africa plummeted to just 0.5% in 2011. Recent coups in Mali and Guinea-Bissau could have wider economic repercussions. "Mali was scoring very well, now we are back to square one," says Mthuli Ncube, the AfDB's chief economist. Ethiopia, Kenya, Uganda and other countries have militarily engaged in Somalia, which may slow their economies. And Nigeria is grappling with Boko Haram, a terrorist sect in the north of that country.

A cause for concern which many are referring to as Africa's "jobless recovery." Investors are concentrating on the extractive sector, specifically gold and diamonds, as well as oil, which generates fewer employment opportunities. 60% of Africa's unemployed are aged 15 to 24 and about half are women. In May, UNDP raised an alarm over food insecurity in sub-Saharan Africa, a quarter of which 860 million people are understurnished.

But none of this is deterring South African business interest north of the border. One may ask why? South Africa's domestic market is not providing local companies with enough growth opportunities, prompting many of them to look at the rest of the continent. This according to Ernst & Young's Africa Business Center's leader, Michael Lalor in an online press conference recently: "While South Africa is still growing well compared to the advanced economies, it's certainly not keeping up with some of the other rapid-growth markets." Says Lalor.

Analysts are pointing out that many of the other emerging markets, such as China and South America, are difficult to enter, making the rest of Africa the obvious choice. Asia is seen as almost excessively competitive. Latin America ventures mean dealing with a very strong and ever present Brazil. Therefore Africa, given its sustainable growth story and its potential, is an area for South African companies to grow into.

Quoted by howemadeitinafica.com Lalor says that most Johannesburg Stock Exchange-listed companies are currently developing strategies for the rest of the continent. Ernst & Young is experiencing strong interest from foreign companies to invest in the continent. "The response from our clients and from potential investors is overwhelmingly positive, to the extent that we simply can not keep up. So there's no doubt that we are seeing significant interest, both spoken, interest in spirit, but also people putting their money where their mouths are, "he said.

These sentiments are confirmed by a survey done last year by Price Waterhouse Coopers. A CEO survey published by PwC found that 94% of South African company heads expected their business in Africa to grow in the next 12 months. PwC interviewed 32 South African CEOs in the ICT, financial services, and consumer and industrial products and services industries.

With this in mind it's worth turning to Raymond Booyse, founder of consultancy firm Expand into Africa, who identified four mistakes often made by South African companies venturing into the rest of the continent.

The first was: Not doing your homework. South African firms are frequently not prepared to spend money on market research. "Go and look if there is a market for your products or services. After you've established that there is indeed a market, find out who your competitors will be," says Booyse.

Booyse points out that South African companies underestimate transport costs and ignore how local laws and regulations influence doing business.

Secondly: Ignorance. Many South African business people are ignorant of local cultures and attitudes according to Booyse. By way of example, ignorance does not realize that just because they're both former Portuguese colonies, what works in Angola's capital Luanda, does not necessarily mean it will work in the northern Mozambique. In a recent report, research firm Nielsen noted that African consumers' attitudes towards technology, fashion and how to spend leisure time vary greatly. No prizes for that one.

Thirdly: Arrogance. Booyse says that South Africans sometimes think they know what people in the rest of the continent need. "In the rest of Africa, South Africans are often regarded as arrogant."

Finally: Not being prepared for the high costs of doing business in Africa. Many South African companies are not aware of the high costs involved in doing business in the rest of the continent. "If you want to spend two weeks in Angola it will cost you R40,000 (US $ 4,700)," notes Booyse. "It is not cheap and easy." Flights for example, from South Africa to either Kinshasa or Lubumbashi can be cheap, and hotel rates are also very high.

It's clear that Africa is a fertile place to plant seed. But Africa is not for the fault-hearted as business is done in a very different way to elsewhere in the world, with all manner of social and political hoops to jump through. South African companies have a potentially bright future and definite advantages if they are prepared to take risks, stay humble and do their homework.
