In a very interesting article published today it was suggested that food production around the world must rise by half in the next 30 years to sustain a global population expected to top 10 billion by 2050.
Utilising more land for agricultural production is one of the answers to solving the potential problem but there are many more. Some of those alternatives are increased organic farming and shifting consumption patterns, permaculture, urban farming and technology.
People are mistaken in the belief that intensive farming produces most of the world's food. There are reported to be more than 570 million farms worldwide and more than 90% are run by an individual or family and rely on family labour. Those farms are producing approximately 80% of the world's food. Small farmers are going to be key to such a transition.
