New study finds 400,000 farmers in southern Africa using 'fertilizer trees' to improve food security

As World Food Day puts focus on food crises, research shows potential for rapid, radical transformation on smallholder farms

NAIROBI, KENYA -- On a continent battered by weather extremes, famine and record food prices, new research released today from the World Agroforestry Centre documents an exciting new trend in which hundreds of thousands of poor farmers in Southern Africa are now significantly boosting yields and incomes simply by using fast growing trees and shrubs to naturally fertilize their fields. 

The analysis of two decades of work to bring the soil-enriching benefits of so-called "fertilizer trees" to the nutrient-depleted farms of Africa was published in the most recent issue of the International Journal of Agricultural Sustainability. 

"In only five African countries, there are now some 400,000 smallholder farmers using fertilizer trees to provide critically needed soil nutrients -- and many report major increases in maize yields -- which shows that it is possible to rapidly introduce innovations in Africa that can have an immediate impact on food security," said Oluyede Ajayi, Senior Scientist at the World Agroforestry Centre and the paper's lead author.
