E. How to match resource flows for competitive food production in cities?

- Mats Eklund, Linköpings Universitet

Food consumption in cities depends on food production that is not always sustainable.

Vegetables are often grown using finite, fossil, resources. Some important inputs for

growing vegetables in greenhouses are heat, carbon dioxide and nutrients. They are

all generated by societal activities and mainly considered as a problem. How can

these resource flows be matched? In this session you will hear about innovative

approaches to the development of food production in greenhouses in the Netherlands.

There will also be presentations about ground-breaking initiatives aiming at

developing greenhouse industry based on available resources that are not used

today.
