In geography, a region is an area of land that has common features, which can be natural or artificial. Regions are the basic units of geography, and they are broadly divided by physical characteristics, human impact characteristics, and the interaction of humanity and the environment. Regions can be defined by a variety of factors, including physical geography, cultural geography, environmental geography, and more. The concept of regions is important and widely used among the many branches of geography, each of which can describe areas in regional terms.

Regions can be categorized into different types based on their defining characteristics. Some common types of regions include:

• Physical or Land Region: This type of region is defined by geographic boundaries and characterized by natural features such as deserts, mountains, and lakes.

• Cultural Region: This type of region is defined by cultural or social characteristics such as language, government, religion, and ethnicity.

• Administrative Region: This type of region is defined by political boundaries established for administrative convenience.

Regions are important to human geographers because they allow us to generalize about a common characteristic so we can better group and understand different areas of the world. The concept of region is currently used in analysis, planning, and administration of many national and international public programs.
