Natural disasters occur without notice and can destroy lives and livelihoods of many based on the scale of destruction left in its wake. Such disasters are inevitable and its consequences even worse. The loss of lives and assets almost always leaves behind suffering.
In mid 2018, Kerala experienced massive floods which brought a death toll over 483. The devastating rains and floods had swept away homes, infrastructure and farmlands from 10 districts with property damage of 5.6 Billion USD. The floods have hit again this year, causing further damage, with the death toll already crossing 120 and over 26000 people in refugee camps across the state. Kerala, Gujarat, Karnataka, Maharashtra, Uttarakhand, Himachal Pradesh are all struggling through floods this year in India.
