 Conduct a thorough review of existing approaches among WASH disaster relief organisations. Bangladesh is vulnerable to numerous natural disasters and every year natural disasters disrupt the lives of people in some parts of the country ( ref). The major disasters affected here are floods, cyclones and storms, flash floods, droughts, tornadoes and landslides. These extreme natural events are defined as disasters when they negatively affect the entire environment and cause serious damage to economic, social and human life (ref). Human vulnerability to any disaster is a complex phenomenon with social, economic, health and cultural dimensions . The relationship between natural disasters and communicable diseases is often misunderstood. The risk of epidemics is high in the chaos that follows natural disasters. However, risk factors for post-disaster epidemics are mainly associated with population displacement and damage to infrastructure. The availability of safe water and sanitation, the degree of crowding, the health status of the population, and the availability of health services all interact with the local disease ecology to increase the risk of communicable diseases and death in the affected population . Several Development organizations are currently conducting WASH interventions in Bangladesh to improve environmental and behavioral factors on community health. ICDDRB initiatives (referring to WASH Benefits and ICVB) are also exploring community-adapted WASH infrastructures to increase the adoption of WASH services and behaviors. However, none of this research addresses highly vulnerable and disaster-prone areas. To fill this gap, we propose disaster vulnerability and identify WASH needs. Therefore, we chose to use a conceptual model adapted from Grant, et al. 2003 to document factors that influence WASH vulnerability and needs. Vulnerability to disasters can be influenced by social and environmental moderating factors. WASH vulnerability can be characterized as stressors or mediators. Research findings can inform WASH practices in disaster contexts to improve outcomes (health, recovery, infrastructure development, disaster risk reduction, etc.) Works Cited Keim ME: Building human resilience: the role of public health preparedness and response as adaptation to climate change.
