This video shows how farmers in East and Southern Africa have been benefiting from increased rice yield after implementing SRI management practices. By following some simple principles in how to transplant the rice seedlings, maintain soil health, carefully irrigate, and manage weeds and nutrients, farmers can now produce a lot more rice than they used to using traditional methods.

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.
