This week you will revise the optional unit for resource management. You will have studied either food, water or energy. This page focuses on food. It would help if you covered the following:
Demand for food resources is rising globally but supply can be insecure, which may lead to conflict:
Areas of surplus (security) and deficit (insecurity):
