This study explores the impact of urban expansion on land use in Gadaref city by using remote sensing technology and geographical information systems.

The city therefore faces a problem of urban expansion and unplanned land use in view of proper land use and land management standards.

The main objective of this study is to explore the levels of urban expansion in the city, the types of land use and revealing the role and importance of remote sensing technology and geographical information systems in the study of urban expansion and its impact on land use.

The study bases its findings on information from the Geodatabase for land use and management in Gadaref city.

The study used “land sat “Satellite images from different time periods in order to establish the extent and percentage of urban expansion, ranging from residential areas, square meters, percentage of land use inside the city, villages, and farmlands surrounding the city.

The study revealed different patterns of land use in which the city has responded to the ever-increasing demands of its residents, and how these patterns violate proper land planning and management standards.

The study revealed disorganization in urban expansion, a lack of monitoring instruments, and violation of land use and management standards by construction companies with regards to conservation of farmlands.

The study confirmed the existence of a reasonable relationship between land use planning and land management, just as it revealed the stages of city expansion.

In the same breath, the study revealed a possibility to assess measure and evaluate land use by using remote sensing technology and geographical information systems in case there exists a dependable area geographic database.

This technology is considered one of the leading instruments in this transformation because its flexibility and comprehensive nature allows it to assess land use patterns and solve challenges that accrue to management and administration of urban expansion.

The study therefore strongly recommends the use of remote sensing technology and geographical information systems in land use planning and urban expansion in Gadaref city
