General information

Guangdong is one of the southern provinces of China, with a population of 100 million people. Compared to the other CORIGAP countries, its population is similar to that of Indonesia.

Guangdong’s total rice area is 2 million hectares, which produces 40% of the province’s rice needs. More than 90% of the food produced in the province is from rice, but the average rice yields is among the lowest in the country, which is about 15% lower than the national average.

To help farmers increase rice productivity, three controls technology (3CT) and alternate wetting and drying (AWD) or intermittent irrigation, was introduced.

At least 2.2 million farmers are estimated to be using the 3CT annually in Guangdong and provinces of Jiangxi, Guangxi, Hainan, Fujian, and Zhejiang.
