Yet, these are being damaged and overexploited, ultimately to the detriment of humans. In addition, increasing incidence and intensity of natural disasters and climate change are having over-arching impacts on the environment. Sustainable development, often of the most vulnerable sectors of society, is thus being undermined. One of the key reasons why this damage continues is that an integrated approach is adopted rarely in disaster risk management. For example, relief organisations may focus on damage to life and property while others examine impacts on livelihoods. Very often, ecological services and their indirect economic values are omitted completely from assessments. Adaptation to climate change is ignored. Mainstreaming ecosystem concerns – both ecological and economical – into the development agenda and integrating them into disaster management, therefore, becomes essential. This manual attempts to provide background information and guidance for integrating environmental concerns into disaster management. Volume 1 of the manual describes briefly the framework of the Millennium Ecosystem Assessment (MA). The MA links clearly ecosystem well-being
