Africa is home to the 10 fastest growing cities in the world. Over the next 25 years, the World Bank projects that the continent's urban population will double to 1 billion. 

Yet along with gleaming skyscrapers and shopping malls, African cities are feeling growing pains. More than half of the 4 million people in the Kenyan capital Nairobi live in slums, often without access to running water, electricity or sewage systems. Traffic in Nairobi and other booming cities has become nightmarish. 

On this edition of Global Journalist, a look at the huge planning and infrastructure challenges for African cities as they undergo one of the most rapid periods of urbanization in world history. Will tomorrow's African megacities be economic powerhouses or giant slums?

Overpopulation has been debated since British economist Thomas Malthus famously warned in 1798 that humans could reproduce far faster than they could increase their food supply.

But since Malthus's time, world population has grown from 800 million to 7.5 billion today. Yet worries about overpopulation are back. In part that's because lots more people are on the way, complicating efforts to deal with problems like climate change and water scarcity.

The UN forecasts that in the near future the world will add about 83 million people annually. By 2100, world population will grow to 11.2 billion.

On this edition of Global Journalist: a look at the growth of human population and the debate about its risks.

Ebola epidemic continues

Since our last program on Ebola, the death toll from the disease has more than doubled to 4,800. U.S. and Spanish aid workers sickened by Ebola also transmitted it to medical workers in the U.S. and in Spain - causing widespread media coverage - and leading people to talk of an epidemic of “Fear-Bola.” But there is good news. The West African nation of Liberia has been hardest hit by the disease, with an estimated 6,500 cases. But last week the country reported just 89 new probable cases.

There has been a lot of media coverage lately dedicated to the spread of the Ebola virus in Africa, which is estimated to have killed at least 2,300 people. The outbreak began in December 2013, when the first cases of Ebola virus were reported in Guinea, located in western Africa. Since then, the disease has spread to neighboring Senegal and Sierra Leone, and from there to Liberia. Both the U.S. Centers for Disease Control and Prevention, and the World Health Organization, warn that unless immediate action is taken quickly, the outbreak could become unmanageable.

Kenyans that want to hear the latest international news can listen to the BBC, the Voice of America, or Al-Jazeera. Africans can also tune in China Radio International, which is gaining ground in the crowded market.
