Main Objectives

The core objective of the SENSUM project is to develop methods and tools to tackle rapidly varying vulnerability and risk within a common framework, by integrating the most effective remote sensing technologies with in-situ surveys and data collection activities. This will allow analysts to deal with risk assessment as a continuous process where information coming from current and future data sources will be seamlessly integrated into a dynamic, multi-resolution and uncertainty-aware model. Addressing the spatial- and temporal-scale related issues will contribute to rationalising data management for multiple natural hazard assessment and vulnerability reduction, and will support cost-effective decision-making with regards to structural and nonstructural mitigation/adaptation measures. The project addresses five major objectives related to this core aim:

1) To address the application of the currently most advanced and next-generation remote-sensing technologies for dynamic multiple-hazard vulnerability analysis and mapping, within a multi-temporal, multi-scale framework. This will be achieved by:

  • (a) Addressing multi-temporal, multi-scale remote sensing processing and integration for vulnerability mapping.
  • (b) Assessing the application of remote-sensing-based global products, such as the Global Urban Footprint, to dynamic multi-resolution vulnerability analysis.

2) To analyse and map short- and medium-term temporal and spatial dependency of multiple hazard vulnerability and risk, with a particular focus on the integration of space-borne data with ground-based information/data sources involving the following:

  • (a) Selecting effective, user-driven adaptive approaches to integrate multi-hazard information with remotely sensed data for vulnerability and risk assessment.
  • (b) Developing an adaptive, dynamic multi-resolution framework for vulnerability analysis and monitoring, implementing optimised sampling from different information sources and integrated management of uncertainties and information life-cycle.
  • (c) Implementing a dynamic, multi-resolution vulnerability analysis and mapping tool as a free, open-source IT framework.

3) To exemplify the application of the methodologies and tools implemented in the SENSUM project by considering seismic and landslide hazards.

While the tools and methodologies developed within the project could be applied to different natural hazards, we chose two relevant natural threats to exemplify the application of the project outcomes in three test-sites. Seismic and landslide risk are often directly connected (i.e., landslides can be triggered by a earthquake) and the associated vulnerability often shows an element of time-dependency. Moreover, in the case of landslide risk, temporal changes occur over the short/medium term, while also being affected by climate change.

4) To thoroughly test and validate the proposed approaches within selected, test cases, working side-by-side with end-users.

Validation is crucial to assess the potential impact of the proposed approaches to the seismic risk communities. Since we are interested in a multiple scale assessment, particular emphasis must be given to devising sound, innovative theoretical and practical frameworks to test and validate vulnerability and risk models. Three test-sites have been selected together with the involved end users:

  • Cologne (Germany),
  • Izmir (Turkey),
  • The cross-border areas between Isfara and Batken (Kyrgyzstan and Tajikistan).
