The adoption of fertilizer trees on farms is a simple and effective way to improve soil fertility, food productivity and therefore contribute to food security. Yet, there is still little empirical research that documents the impact of fertilizer trees on food security among smallholder farmer households. Researchers from the World Agroforestry Centre carried out a study in Malawi to analyze the impact of the adoption of fertilizer trees on food security among smallholder farmers

It is predicted that the population of China will stabilise at 1.6 billion within the next two decades. In order to feed this many people, crop production will need to increase by 2% each year to provide the estimated 580 million tonnes of grain that will be required. Mingsheng Fan and colleagues have published a review of past trends in agricultural production in China and the solutions that they think will allow China to produce more food in the future without an increase in available agricultural land. The main crops produced in large quantities in China are cereal crops, particularly wheat, maize and rice. The main limiting factors for the continued increase in agricultural production are water availability and soil quality. There is also the requirement to reduce use of nitrogen and phosphorus fertilisers because they pollute the air and water.
