Distribution characteristics of agricultural areas in Southeast Asia

Seasonality means that Southeast Asia has a tropical monsoon climate, with hot and rainy summer and warm and dry winter, which is not suitable for planting crops in winter. Regionality refers to the rugged terrain in Southeast Asia, where agriculture is generally located in the valleys and plains downstream of rivers. Periodicity should refer to the fertility of soil, and crops will lose fertility if planted for a long time. So cut the time.
