Final answer:
Rainfed lowland rice areas are characterized by sufficient precipitation, wetland rice farming, and the ability to grow two crops per year. Rice cultivation in these areas is more productive than other grains.
Step-by-step explanation:
Characteristic of rainfed lowland rice areas include:
- The presence of sufficient precipitation, particularly in tropical and coastal regions
- The focus on wetland rice farming in fertile areas such as the southern Irrawaddy basin
- The ability to grow two crops of rice per year in regions with a longer growing season
Rice cultivation in these areas requires flat, submerged fields and a water-regulated environment to control temperature and weeds, dissolve nutrients, and ensure optimal growth. The cultivation of wet rice is more productive compared to other grains, allowing for higher food production per acre.
