Environmental security is an increasing issue in world affairs. Environmental security is the state of human-environment dynamics that includes restoration of the environment damaged by military actions, and amelioration of resource scarcities, environmental degradation and biological threats that could lead to social disorder and conflict NATO continues to list environmental security as among its most important priorities. Without greater measures to insure environmental security, continued population and economic growth will diminish natural life support systems leading to migration and conflict. With half the world clustering into urban environments, natural disasters and global environmental change affect greater numbers of people who are dependent on civil systems for water, power, transportation, food and other manufactured systems. Security for environment, water management and information is becoming major necessity due to terrorism and heighten level for the quality of human life. New advanced methodologies which are Geographic Information System (GIS) and Remote Sensing (RS) important tool to determine and help to solve described problems to monitor environment for risk assessment and management are needed to meet new challenges including terrorist attacks. Some projects using remote sensing methods with satellite data and GIS software which are subjected to monitor water quality and urban chancing up to time at the drinking water basin and dam will be shown, giving examples on how this integration of multisource information works now and advise the new technologies in the near future.
