Final answer:
Upland rice areas are characterized by rugged and mountainous terrain, but with advanced engineering techniques like terracing and irrigation systems, rice cultivation is possible.
Step-by-step explanation:
Upland rice areas are characterized by rugged and mountainous terrain. Rice is typically grown in flat, submerged fields, so mountainous areas are not naturally suited for rice cultivation.
However, with advanced engineering techniques such as terracing and irrigation systems, farmers in upland rice areas have been able to transform the landscape and cultivate rice successfully. Examples of upland rice areas can be found in regions like the Banaue Rice Terraces in the Philippines and terraced rice paddies in Longsheng, China.
