Recently, climate change and human activities accelerate hazards, such as deforestations, land slides, draughts, floods in Asian-Pacific countries are increased. To mitigate the hazards due to climate change and human activities, environmental monitoring has become important. Environment change monitoring by using space based technology are very important. Asian Pacific regional forum (APRSAF) agreed to host SAFE (Space Applications For Environment) initiatives. Under APRSAF, there are on-going several SAFE prototyping for water management, agriculture, fishery and coastal monitoring This paper describes SAFE overview and current situation of SAFE prototyping.
