By looking at the world as a range of ecosystems (from pristine nature to highly intensive agriculture)and recognizing their variety of ecosystem services, agroecosystem functions can be managed sustainably for current and future food security.


It has become widely accepted that food security is not only a matter of food production but also an issue of equal and secure access to the means of production and to food products (FAO 2010).


This blog focuses primarily on how to achieve sustainable food production from a biophysical perspective and does not address per se the key social and institutional issues related with food security.


Several of those are however highlighted throughout the text in order to remind the reader that these remain a critical component to ensure food security for the poor and socially-disadvantaged groups.
