How can you differentiate upland from lowland tribal groups?

Upland tribal groups are typically found in hilly or mountainous regions, often engaging in agriculture suited to steep terrains, such as terrace farming, and may practice shifting cultivation. In contrast, lowland tribal groups generally inhabit flatter, more fertile areas, relying on rice paddies and other forms of agriculture that benefit from the accessibility of water resources. Cultural practices, social structures, and subsistence strategies also vary, reflecting adaptations to their respective environments. Additionally, upland tribes may have more isolated communities, while lowland tribes often have greater interaction with neighboring populations.
