Food vs fuel. Land-use change. Global food miles. The use of land for food, fuel, feed and materials is already a major issue and will increase in the coming years as the population continues to expand. Within the sustainable sciences there is a big push to use renewable resources but how can we do this without negatively impacting on other uses of land? How can we increase food supply in a world with increasing costs for fossil fuels and scarcity of some of the major nutrients: potassium and phosphorous?

You can learn about some of these issues on a new online course ‘Global Food Security: Addressing the Challenge.’

The course is free and runs for 8 weeks, requiring about 3 hrs per week of time.
