This chapter supports SDGs 3 and 16 by exploring complex emergencies and how displaced populations are at increased risk of increased morbidity and mortality.Disasters, either natural or man-made, disrupt the baseline functioning of a community, including food, water, sanitation and health. The resiliency of a community to recover from a disaster depends on existing economic and social structures. Poverty and inadequate economic and social systems are prevalent in tropical regions, making them extremely vulnerable to disasters.
