Throughout this paper I aim to bring my readers along my practical and academic journey during my internship with child's rights-based NGO CRY. In a period of uncertainty and restrictions imposed by the onset of COVID-19, NGOs, in the field of social and sustainable change, such as CRY, are in need of a guide on how to best continue their activities and preserve their intended effects for the communities, I thus attempt at providing a theoretical answer to this inquiry through the concepts of adaptation, community resilience, vulnerability reduction assessment and a number of other important aspects to consider in these circumstances. This research becomes not only relevant in the present, for NGOs such as CRY, yet also in the future due to the likely perpetuation of pandemics like COVID-19.
