THE United Nations food agency is calling for greater use of environmentally sustainable techniques by poor farmers in order to increase crop intensity to feed the world's growing population.
"The new approach calls for targeting mainly smallholder farmers in developing countries," the Rome-based Food and Agriculture Organisation (FAO) said in a statement accompanying a report entitled "Save and Grow".
"Helping low-income farm families in developing countries... economise on cost of production and build healthy agro-ecosystems will enable them to maximise yields and invest the savings in their health and education," it said.
"In order to grow, agriculture must learn to save," it said, pointing to lower crop yields in recent years despite an increase in environmentally unsustainable farming practices aimed at increasing intensive farming.
The eco-friendly techniques recommended by FAO include using plant residues to cover over fields, rotating cereals cultivation with soil-enriching legumes, more precise irrigation for fields and better use of fertilisers.
"Such methods help adapt crops to climate change and not only help grow more food but also contribute to reducing crops' water needs by 30 per cent and energy costs by up to 60 per cent," the report said.
"In some cases crop yields can be increased six-fold, as shown by trials with maize held recently in southern Africa," it said.
"Average yields from farms practicing the techniques in 57 low-income countries increased almost 80 per cent," it added.
FAO called on governments both in the developed and in the developing world to increase investments in order to provide incentives for poor farmers to adopt the new, more environmentally friendly farming techniques.
