In the May 2014 National Geographic magazine an article was written entitled 'A five step plan to feed the world' by Jonathan Foley.
It does what it says on the tin, it sets out a five step plan which will enable the world to produce enough food to reads the worlds population without totally destroying (my words) the environment.
A link to the article can be found at http://www.nationalgeographic.com/foodfeatures/feeding-9-billion/. You will need to scroll down to read the article.
