Establishment of a scientific society like HiLS requires a set of strategic goals, and global-to-local actions must be identified to substantially reduce the effects of landslide disasters and environmental changes on life and livelihood of people in the Himalayas over the upcoming decades. To set the goals and to promote appropriate global-to-local actions, HiLS will bring all researchers in the field of landslides and environment in the Himalayas into a single room, and will coordinate landslide and environmental research activities in the Himalayas from a global perspective in order to improve the quality of people's life in the Himalayas. HiLS is intended to facilitate and advocate discussions on the major issues of landslide and environmental research, which must be addressed to design effective methods for landslide disaster reduction and environmental protection in the Himalayan Region. With these issues in focus, the main aims and objectives of HiLS are as follows.
