Abstract
This paper presents the current state and development of a prototype web-GIS (Geographic Information System) decision support platform intended for application in natural hazards and risk management, mainly for floods and landslides. This web platform uses open-source geospatial software and technologies, particularly the Boundless (formerly OpenGeo) framework and its client side software development kit (SDK). The main purpose of the platform is to assist the experts and stakeholders in the decision-making process for evaluation and selection of different risk management strategies through an interactive participation approach, integrating web-GIS interface with decision support tool based on a compromise programming approach. The access rights and functionality of the platform are varied depending on the roles and responsibilities of stakeholders in managing the risk. The application of the prototype platform is demonstrated based on an example case study site: Malborghetto Valbruna municipality of North-Eastern Italy where flash floods and landslides are frequent with major events having occurred in 2003. The preliminary feedback collected from the stakeholders in the region is discussed to understand the perspectives of stakeholders on the proposed prototype platform.

Summary
The losses caused by the natural disasters have risen with severe impact, on the poor. Some examples of prevention include dams to eliminate flood risks and land-use planning regulations to restrict any settlement in high risk areas This prevention task transforms to mitigation when complete avoidance of losses is not possible. With the help of advanced web services, standards and geospatial technologies such as remote sensing and photogrammetry, Geographic Information Systems (GIS), Global Positioning Systems (GPS), Spatial Data Infrastructure (SDI) and Open Geospatial Consortium (OGC) web services, nowadays, it is possible to deliver, access, analyze and share rich spatial information over the web This is relevant to the emergency response and disaster management activities since it is important to rapidly share, integrate and apply geospatial information. This paper reports on the development of a prototype web-based participative decision support platform to aid in the selection of different risk reduction strategies, in particular for flood and landslide management, using open-source software and decision technologies.
