Food security in Liberia

Fifteen million tonnes of bananas are shipped around the globe every year. Consumers in the developed world have become use to exotic fruit and vegtables at all times - but the UN believes the best way to ensure nine billion people are fed and watered by 2050, is to produce and consume a significantly larger proportion of locally grown food.

On this week's One Planet we consider how resilient our global food chain is. We visit Europe's largest banana ripening warehouse; we hear from the community who are trying to bypass the food chain by growing everything themselves, plus we hear from Liberia - a country that is struggling to rebuild its agricultural sector after years of civil unrest.
