Objectives: This study examines the impact of evaluation criteria—relevance, coherence, and effectiveness—on the success of humanitarian projects in the Gaza Strip, with efficiency as a mediating factor. It aims to provide a comprehensive understanding of how these criteria interact to enhance project outcomes in complex humanitarian settings. Methods/Analysis: The research employs Structural Equation Modelling (SEM) to analyze data collected from 350 respondents involved in humanitarian projects. The analysis assesses the direct and mediated effects of relevance, coherence, and effectiveness on project success, offering empirical insights into the role of efficiency in optimizing resource utilization. Findings: The results indicate that relevance, coherence, and effectiveness significantly influence project success, while efficiency strengthens these relationships by ensuring better resource allocation and implementation. The study highlights the importance of community engagement, alignment with local needs, and cultural sensitivity in achieving sustainable project outcomes. Novelty/Improvement: This research presents an integrated evaluation framework that enhances understanding of the interplay between key project assessment criteria and efficiency in humanitarian work. The findings provide actionable insights for organizations operating in complex environments like Gaza, helping refine project planning and execution strategies to improve sustainability and impact.

This paper examines the factors that influence humanitarian resilience, explicitly focusing on the mediating role of community engagement. Humanitarian resilience is a critical aspect of disaster management and response, and understanding the underlying factors and the role of community engagement in enhancing resilience is paramount This study investigates the multifaceted factors influencing humanitarian resilience among the youth population of the Gaza Strip, focusing on the variables of humanitarian aid funding, logistical support, and humanitarian personnel. Employing quantitative research methodology and Structural Equation Modelling (SEM) techniques, we explore the mediating role of community engagement in shaping the dependent variable of humanitarian resilience. In a sample of 429 youth residing in the Gaza Strip, our research assesses the direct impacts of funding humanitarian assistance, logistical support, and the presence of humanitarian personnel on the participants' resilience levels. Furthermore, we examine how community engagement mediates the relationship between these factors and the overall level of humanitarian resilience. This innovative approach aims to provide a comprehensive understanding of the intricate dynamics in the context of humanitarian assistance in the Gaza Strip. The findings of this study hold significant implications for policymakers and humanitarian organizations operating in conflict-affected regions. By elucidating the mediating influence of community engagement, we shed light on potential strategies to enhance the resilience of individuals and communities in the face of adversity, ultimately contributing to the effectiveness of humanitarian efforts in the Gaza Strip and similar contexts worldwide.
