Abstract: Non-Governmental Organizations (NGOs) in developing countries persist in the difficulty of sustaining operations due to constrained and volatile resource availability. Operating in unpredictable and risk-prone environments further complicates this challenge. This paper explores how project risk management shapes resource mobilization efforts among NGOs. Deducing from the Resource-Based View theory (Barney, 1991; Werner felt, 1984), it argues that strong risk identification, risk assessment, and risk mitigation practices enhance organizational credibility, uplift stakeholder confidence, and increase access to long-term funding. Evidence from previous studies (Asawo et al., 2021; Micheni et al., 2025; Mmaitsi, 2020) demonstrates that Managing Uncertainty in Projects serves as a strategic tool for resource mobilization by building donor trust and ensuring project sustainability. This paper proposes a Project Risk Management resource mobilization framework and recommends institutionalizing risk management as part of NGO fundraising and donor-engagement strategies. Keywords: Uncertainty Management, Adaptive resource mobilization, Project Success.
