- 17. Conclusion • Urbanization can change the land use patterns and alter the landscape. • The changes in land use of Tehsil Sargodha during the last 24 years indicate that there is 17.4% increase in urban area and 6.5% in bare land. Overall change in category of water is -16.4% and -7.5% in agricultural land. • Several problems arise due to urban sprawl such as traffic conjunction, urban slums, environmental degradations, climate change, poor water and air quality and land use/and cover changes. • Therefore, it is suggested that separate detailed studies should be taken up regarding these problems. 17
