In the past few years, people all over the world have been horrified by the damage and chaos that have happened in many countries. Even though these things may have happened in different ways, they all have one thing in common: most of the people who are hurt are women, children, the elderly, minorities, and people with disabilities who are either forced to move or have their belongings stolen. This is because of environmental degradation. Many disaster theorists have made it clear how the social structure and roles cause a lot of pain and different effects on different people. The goal of the current study is to find out how the environmental degradation with special emphasis on flood in India and Bangladesh affect the lives of poor and marginalized people and how that affects them in the form of movement and often forced migration. If you look closely, you can see that men and women are vulnerable in different ways and to different degrees during tragedies based on their abilities and choices. Because of a lack of understanding of gender differences and a lack of sensitivity to them, women can't participate in development processes. Instead, they are forced to move to other places with their children and elderly family members without their husbands or elderly male family members, which put many women and girls in danger and leads to other kinds of inequalities in the enjoyment of human rights, political rights, and economic rights. The researchers have looked at a lot of secondary data to figure out how disasters and forced migration affect women and children in flood-affected areas of India and Bangladesh.
