Why are there a lot of water conservancy projects in monsoon paddy field agriculture? What are the characteristics of monsoon paddy field agriculture?

1, monsoon paddy field agriculture is a unique agricultural type in tropical and subtropical humid areas. Mainly distributed in East Asia, Southeast Asia, South Asia monsoon region and Southeast Asia tropical rain forest region. Irrigation is the basis of rice production. Frequent floods and droughts in monsoon region pose a great threat to rice production. Small-scale farmers are unable to build water conservancy projects, so they need a lot of government investment to organize water conservancy projects. Therefore, the amount of agricultural water conservancy projects in monsoon paddy fields is large.

2, in addition to a large number of water conservancy projects, monsoon paddy field agriculture has the following characteristics:

Small-scale farming: rice production in monsoon paddy fields is family-based. Due to the shortage of cultivated land per capita, every household has little cultivated land.

High yield per unit area: farmers intensively cultivate in the fields, which makes the yield per unit area of rice higher. However, due to the small scale of production, the total output of rice per household is not large.

Low commodity rate: Limited by traditional ideas and economic level, farmers keep a considerable part of the collected rice for their own use, while the rice sent to the market for sale is very limited.

Low level of mechanization and science and technology: farmers generally engage in manual labor. Although electric irrigation and threshing have developed rapidly in the last two decades. But in general, the level of mechanization and science and technology is still relatively low.
