<p><strong>Abstract.</strong> Comprehensive and sustainable landslide management, including identification of landslide susceptible areas, requires a lot of organisations and people to collaborate efficiently. Often, landslide management efforts are made after major triggering events only, such as hazard mitigations that applied after the 2015 Gorkha earthquake in Nepal. Next, to a lack of efficiency and continuity, there is also a lack of sharing of information and cooperation among stakeholders to cope with significant disaster events. There should be a system to allow easy update of landslide information after an event. For a variety of users of landslide information in Nepal, the availability and extraction of landslide data from the database are a vital requirement. In this study, we investigate the requirements to and propose a concept for a web-based Nepalese landslide information system (NELIS) that provides users with a platform to share the location of landslide events for the further collaborations. The system will be defined as a web-based geographic information system (GIS) that supports responsible organisations to address and manage different user requirements of people working with landslides, thereby improving the current state of landslide management in Nepal. The overall aim of this research is to propose a conceptual design of NELIS and to show the current status of the cooperation between involved stakeholders. A system like NELIS could benefit stakeholders involved in data collection and landslide management in their efforts to report and provide landslide information. Moreover, such a system would allow for detailed and structured landslide documentation and consequently provide valuable information for susceptibility, hazard, and risk mapping. For the reporting of landslides directly to the system, a web portal is proposed. Stakeholders who can contribute to the reporting of landslides are mostly local communities and schools. Based on field investigations, literature reviews and user interviews, the practical structure of the landslide database and a conceptual design for the NELIS platform is proposed.</p>
