Competition over resources
In the environmentally constrained but more populous world that can be expected over the course of this century, there will be greater scarcity of three key resources: food, water and energy. Demand for all three resources is already beyond that which can be sustained at current levels. Once population growth and the effects of climate change are factored in, it is clear that greater competition for such resources should be expected, both within and between countries, potentially leading in extreme cases to conflict.

Sub-Saharan Africa is too readily dismissed from the outside, but the regional perception is often one of optimism. It is an area rich in natural resources: ranging from oil and natural gas to other minerals such as chrome, nickel and zinc. Nearly half the population are under the age of 14, making the region free from the demographic burden of an ageing workforce prevalent in other parts of the world. 
The Middle East and North Africa is a region of great diversity. It encompasses Arab and many other ethnic populations, theocratic and secular states, democracies and authoritarian regimes. A region of immense wealth and crippling poverty; it is blessed (some might say cursed) with vast resources, not least oil, but has not always proved able to manage them for the benefit of ordinary people.
