Barriers to migration refer to obstacles or challenges that individuals face when trying to move from one place to another, such as legal restrictions, lack of resources, cultural differences, or physical barriers like borders or bodies of water. These barriers can make it difficult for people to relocate or seek better opportunities in other areas.
Legal barriers to migration can include visa restrictions, quotas, and strict immigration policies set by governments. These regulations limit the ability of individuals to enter and reside in a country legally. Additionally, concerns over national security and economic impacts can also contribute to legal barriers to migration.
Contour barriers are physical structures that are used to control erosion and redirect water flow along contours of the land.
