depression. Though a few large studies have been conducted, research gaps exist in investigating chronic mental health impacts of humanitarian crises, which is why these estimates have so much variation. PTSD along with moderate to severe depression and anxiety can be life-long disorders without adequate and prompt treatment. Responses The WHO and the Inter-Agency Standing Committee (IASC) recommend that mental health care should be an integral part of emergency response during a humanitarian crisis. The type of mental health care provided can range and vary based on the context and resources but can include mental health first aid on the front lines, community support groups, and routine clinical mental health care. The WHO also recommends that countries enhance their mental healthcare systems outside of the context of a humanitarian crisis so that individuals affected by crises can have access to the care they need once the emergency response is over. A 2020 Cochrane review of psychological and social interventions for the prevention of mental disorders for individuals living in areas affected by humanitarian crisis found the need for better studies to determine the impact of interventions following a review of current studies. Research states that mental health is often neglected by first responders. Disaster can have lasting psychological impacts on those affected. When individuals are supported in processing their emotional experiences to the disaster this leads to increases in resilience, increases in the capacity to help others through crises, and increases in community engagement. When processing of emotional experiences is done in a collective manner, this leads to greater solidarity following disaster. As such, emotional experiences have an inherent adaptiveness within them, however the opportunity for these to be reflected on and processed is necessary for this growth to occur. Sustainable solutions There is no singular solution to any one humanitarian crisis. Often, the primary cause of a humanitarian crisis is intertwined with several other factors. Further, one repercussion can lead to another which may lead to another. For instance, in the case of a flood, fish and ocean life is impacted, an environmental and ecological impact. This can further impact humans the source of income for fishermen, an economical impact. This causes the residents of this particular area to be stripped from their source of food and their culture of consuming sea fish. This can lead to women and children being forced to work in dangerous conditions to gain
