Urban resilience is the capability of urban world to act efficiently in such a way that their residents and working population, particularly the vulnerable people, undergo the shocks and stresses that they encounter in their normal lives. This study makes an attempt to evaluate the impact of climate change on low-income population, equity, health, and well-being in poor urban. Climate change as global social, economical, biological, and natural challenge and threat spatially has two major impacts; first, it affects the poor and vulnerable people; and second, it has long-standing effects for sustainable development. It has been investigated that poor, older age, low economic status, and female are more at risk and vulnerable to climate change and its impacts in urban areas in the globe. This impact is more dominated in low-income residencies and developing nations, where the population lacks basic facilities, low-nutrition food, and poor social, environmental, and natural services. As a result of this crucial issue, this impact becomes gradually deceptive; it is a matter of fact that those who are at most risk will get most affected socially as well as economically. This impact generates a newly emerging term “climatic gentrification,” which is getting more importance around the world among policymakers. The impact of the term gentrification is a crucial issue not only for urban resilience but also create long-term challenges for urban sustainability. The study result will provide fundamental results after a careful and critical investigation to create awareness among policymakers and urban governance to make attempts to minimize this issue to the possible level. Finally, the outcomes of the study will help create an environment for social justice all over the world for urban resilience.
