Philippe Rekacewicz, UNEP/GRID-Arendal]
The lack of food and fresh water may limit the rate of global population growth beyond 2050.
Identify two reasons that may cause food supply to be limiting.
lack of water/poor irrigation/low precipitation; soil degradation;
lack of adequate space/fertile land; pests/disease;
climate change/global warming/extreme weather conditions; natural disasters; overfishing/exhaustion of fisheries;
infrastructure restrictions limiting transport of food; war/conflict limiting availability;
Marking guidance:
Do not accept only 'increase in population results in greater demand which we are unable to meet'. Accept any other appropriate respons.;
