The world today is facing unprecedented crises and growing challenges. 98.5 million people have been affected by disasters in 2015 alone. Over 65 million people have been forcibly displaced both within and across borders, resulting in mounting humanitarian needs which are exceeding available resources. Meanwhile, the rate of globalisation and urbanisation makes the realities of health crises much harder to contain. The World Bank has projected that the share of Africans living in urban areas is projected to grow from 36 percent in 2010 to 50 percent by 2030. The impact of climate change is exacerbating the situation; 2015 was the hottest on record, with 32 major droughts, double the ten-year average.
