In an article entitled, “Climate change could result in decreasing yields of staple food crops in most parts of the world from the 2030s onwards” has been published in the 20th March issue of Nature, 507:27. In this article 
Andrew Challinor at the University of Leeds, UK, and his team have compared the results of more than 1,700 simulations of climate change impacts — with and without various adaptation strategies.
