Disasters affect populations and ecosystems differently, depending on many factors such as socio-economic status, development practices, condition of the ecosystems, level of organization of the community and its human resources, and climate variability and extremes. Deteriorating environmental conditions in many parts of the world, whether due to climate change, unsafe development, or reduced investment in ecosystem protection is intensifying disaster risk, posing a growing threat to lives and development efforts. Disaster risk reduction involves the process of identifying, assessing and reducing the risks of these and other causal factors of disasters. This risk is exacerbated in vulnerable populations, which includes, among others, those who are often marginalized for economic or social reasons, inhabit unsafe lands, or lack access to information to reduce risk.
