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.
Ian Shields writes exclusively for sustainablesecurity.org:
Humanity appears caught in a trap with no way out. ‘Business as usual’ is no longer an option. However, halting and reversing our consumption of more and more ‘stuff’ appears likely to trigger a massive depression with serious unemployment and poverty. This is certainly true if all we do is ‘apply the brakes’ without fundamentally redesigning the whole economic system.
Understandably, the world has become increasingly preoccupied with risk and insecurity. The uncertainties produced by global challenges such as financial crises, economic slowdowns, health pandemics, the international narcotics trade, terrorism and conflict and indeed the impact of climate change are just a few pressing examples causing concern. However, the earth's environmental resources are increasingly under enormous strain and nowhere is this stress more apparent than in the case of the earth's finite supplies of freshwater.
