Border enforcement refers to the policies, practices, and technologies put in place by governments to secure and regulate their national borders. This includes monitoring and patrolling border areas, intercepting illegal border crossings, preventing smuggling and trafficking activities, detaining and deporting unauthorized immigrants, and managing legal entry and exit processes. Border enforcement is a critical component of a country's national security and immigration control efforts, as well as its efforts to combat transnational crimes such as drug trafficking and human smuggling. Researchers in this area study the effectiveness of various border enforcement strategies, their impact on migration patterns and border communities, and the ethical and human rights implications of border enforcement practices.
