Abstract



Insurgency is a threat to the social, political and economic stability of countries. Nigeria has been plagued by insecurities in recent years, especially due to insurgencies in the northern parts of the country. The use of geospatial technology by security planners provides a means for data analysis and presentations which can aid management decisions. This study harnessed geospatial technologies to ascertain land change dynamics in an insurgency affected local government area in Borno State, Nigeria between 2015 and 2020. Landsat 8 (OLI TIRS) imageries of 2015 and 2020 of Hawul Local Government Area were classified using the maximum likelihood classification algorithm to determine the land use changes in the area. Field visit to the local government area was done to determine affected and unaffected communities. Results show that total built up areas 2 2 2 2 increased from 146.53km in 2015 to 360.93km in 2020. Farmlands decreased from 1544.61km in 2015 to 1304.14 km 2 2 while vegetation also decreased from 261.54km to 55.28km in 2020. Insurgency affected communities in the local government increased from 8 in 2015 to 24 in 2020, with unaffected communities having built up expansions while growth was static in most of the affected communities. This indicates a migration pattern due to insurgency in the area. The findings of this study can help in managing the security challenges as well as provide information that may be useful in planning, resource distribution and security management.
