The first issue of Modern Farmer came out recently and there some articles that really caught my attention.
Wild boars, http://modernfarmer.com/2013/04/who-can-stop-these-adorable-pigs/. Apparently we are in big trouble from these animals, they are causing mass destruction of crops in many places and they are difficult to kill. Not only that, but do you recall recent salmonella outbreaks from spinach? They were probably cause not by humans, but from boars.
Climate change and basmati rice, http://modernfarmer.com/2013/04/monsoon-season-finale/. With a change in the timing of monsoons growing basmati is affected and farmers in northern India where it is predominately grown may have to switch to growing corn. This will cause a shortage of basmati and a huge change in diet for the people of this region.
