While there is a bulk of studies about youth-led nonprofit organizations that advocates peacebuilding in postconflict areas, a very minimal research is available focusing on the factors that may influence their sustainability in post-external aid phase. Especially for youth-led non-profit organizations in developing and conflict-driven regions, there is a need to study their current sustainability status which will be the basis for proposing ways to enhance sustainability. Anchored on the organizational sustainability theory of Coblentz (2002) and of Hauser, Huberman, and Alford (2008), this research determines the current sustainability status of the organizations’ operations in post-external aid phase of Move This WorldPhilippines and Dire Husi Initiative, two youth-led nonprofits in Northern Mindanao. A total of 34 organizational sustainability indicators serve as basis in determining the current sustainability status of both organizations. Spiritual sustainability (89%) ranks first among the four dimensions, followed by technical sustainability (86%), then institutional sustainability (70%), and financial sustainability (38%) as the lowest. Challenges related to stakeholders, approach, and resources are identified. Especially for non-profit literature, the empirical data from this study contributes particularly on strategies of enhancing organizational sustainability of youth-led non-profit organizations from developing and conflict-driven regions.
