The city of Riyadh, has gained its population from 1,570,000 people in 1985 up to 7,400,000 people in 2021 due to the urban development requirements. This increase in population left an effect on the city horizontally and sacrificing hectares of natural open areas and agricultural lands to adapt the fast growth of the population in the capital. This paper relied upon descriptive method, historical, and spatial analysis method to describe the stages of urban sprawl on agricultural land in Almasni' district in Riyadh as a case study. Moreover, this paper counted on gathering initial data by distributing a questionnaire on random sample of 272 individuals who are residents of Riyadh city and in addition to a field interview with the farmlands owners and farmers who lives in the area, along with, collecting secondary information from the official sources, such as reports issued by 'Royal Commission for Riyadh City' (RCRC), 'Riyadh Municipality' and 'Ministry of Municipal Rural Affairs and Housing' (MOMRAH). The research found that urban sprawl affected the open natural spaces and contributed to the decline of agricultural lands inside the city. As a conclusion, the research paper proposes developing a comprehensive strategy to administrate and control the agricultural land inside the Saudi city's borders that strengthen the principle of complimentarily between the agricultural lands and the urbanization growth in order to gain full advantage of the natural sources within the orientation of the national vision of 2030.
