The main objective of this research was to study the degree of popular participation of Bedouins in some development projects in North Sinai Governorate. This was achieved by identifying the personal, social, and economic characteristics of the respondents, understanding the nature of the relationships between the independent variables studied and the degree of popular participation of Bedouins in different phases of development projects (planning, implementation, and evaluation), and determining the relative contribution of the studied independent variables in explaining the total variance in the degree of popular participation of Bedouins across these phases. Additionally, the study aimed to identify the problems faced by Bedouins in participating in the various phases of the development projects (planning, implementation, evaluation) from their perspective, as well as their suggestions for overcoming these problems. A random sample of beneficiaries from the planned activities of development projects in Bir al-Abd center in North Sinai was selected, with a total of 411 beneficiary families in the development projects of the area. The sample size was determined using the Yamane formula, resulting in a total of 200 respondents. The study concluded several findings, most notably that approximately 76.5% of the respondents had a high level of participation in the development activities. The results also revealed that ten variables contributed to explaining the variance in the overall degree of popular participation among the respondents, which together accounted for about 48.7% of the variance in popular participation.
