Dar es salaam city in Tanzania like other cities in Africa and elsewhere has been expanding outward to encroach into peri-urban areas. This has resulted into land use change and impact to the livelihoods of the peri-urban household. The study aimed at identifying the impact of peri- urban land use change on people’s livelihood. Specifically the study focused on examining the changes in the peri- urban area based on the analysis of remotely sensed satellite imagery from 1986, 1996, 2006,2016 and predicting the land use change for 2026 as well as analyzing both the factors that contributed to the land use changes. The study used both quantitative and qualitative approaches so as to complement each other. A total of 100 household were randomly selected from whom data were collected through face to face interview quided with a questionnaire. The statistical package of social sciences (SPSS) and Microsoft Excel were used to analyze field data while the images were analyzed using Arc GIS software. The result revealed that there have been land use changes from the year 1986 to 2016. Before 2006, the built up areas were 47.044 Ha which increased to 923.160 Ha in 2016. This meant that a total of 876.116 Ha of Land had been changed from other land uses to built up areas. Likewise for the vacant land which was 4840.989 Ha in 2006, it was reduced to 2264.525 ha. Thu there was a rapid change in land uses, mostly after the urban development project period (after 2006). The predicted land use showed that in 2026 there will be an increase in built-up areas by 650.34 Ha while partial built up and vacant areas were estimate to decrease by 359.37Ha and 346.125Ha respectively. The research revealed that the major factors influencing land use change in Kwembe were planned growth and expansion of Dar es salaam city and the availability of social services in the area. Change of the household’s economic base and adoption of nonfarm activities among some of the household’s were noted to be the main impact of land use change on livelihoods of peri-urban household. The study recommended the need for urban planning providing land for public uses and facilities and areas for economic investment and peri-urban agriculture during land use planning. Also there is a need of create bylaws that will ensure the proper management and control of the use of land in he peri-urban for sustainable livelihoods.
