Guangdong
Bridge between Hong Kong and Shenzhen, Guangdong province, on the Chinese mainland.
The Pearl River Delta supports intensive farming in Guangdong through its fertile alluvial soil and a complex hydrological network that facilitates year-round cultivation.12
Key factors supporting agriculture in the region include:
- Water Management: The delta features a vast, intricate system of over 1,200 miles (1,900 km) of flood dikes and canalized channels. This infrastructure protects fertile islands from the sea and provides the necessary irrigation to sustain intensive crop production.234
- Climate and Growing Season: Due to the region's favorable climate, the delta benefits from a 12-month growing season. This allows farmers to produce three rice crops annually, a higher frequency than in most other cultivated areas of the province.14
- Diverse Agricultural Output: Beyond rice, the delta supports the cultivation of various crops, including wheat, corn, sorghum, beans, and potatoes. Additionally, the region’s waterways are utilized for fish farming, where river waters are sometimes enclosed with bamboo fences to breed freshwater fish.24
This combination of water control, fertile land, and a long growing season makes the delta one of the most productive and densely populated agricultural regions in China.12
