Abstract. In the framework of German Indonesian Tsunami Early Warning System (GITEWS) assessment tsunami risk is an essential part overall activities. The scientific and technical approach for has been developed results are implemented in national Centre provided to regional disaster management spatial planning institutions Indonesia. paper explains underlying concepts applied methods shows some achieved GITEWS project (Rudloff et al., 2009). performed at overview scale sub-national level...
Abstract. This study aims at creating a holistic conceptual approach systematizing the interrelation of (natural) hazards, vulnerability and risk. A general hierarchical risk meta-framework presents potentially affected components given system, such as its physical, demographic, social, economic, political or ecological spheres, depending on particular hazard. Based this meta-framework, measurable indicators are specified for system "urban area" an example. framework is used outline to...
Abstract. Human immediate response is contextualized into different time compartments reflecting the tsunami early warning chain. Based on available and evacuation quantified. The latter incorporates accessibility of safe areas determined by a hazard assessment, as well environmental demographic impacts speed properties assessed using Cost Distance Weighting GIS approach. Approximately 4.35 million Indonesians live in endangered southern coasts Sumatra, Java Bali have between 20 150 min to...
This paper describes the results of a comprehensive analysis for tsunami disaster mitigation in Padang City, Indonesia. Assessment consists several steps, starting from construction hazard maps based on most probable earthquake scenario future. Results are then analyzed to determine impact residential population along potential evacuation routes. Next, standpoint hazards, we move human’s vulnerability during evacuation. The term “vulnerability” is associated with available time. Here,...
Abstract. More than 4 million Indonesians live in tsunami-prone areas along the southern and western coasts of Sumatra, Java Bali. Although a Tsunami Early Warning Center Jakarta now exists, installed after devastating 2004 tsunami, it is essential to develop tsunami risk knowledge within exposed communities as basis for disaster management. These need implement reduction strategies mitigate potential consequences. The major aims this paper are present assessment methodology which (1)...
Abstract. This paper describes the examination of three practical tsunami run-up models that can be used to assess impact on human beings in densely populated areas. The first examined applies a uniform bottom roughness coefficient throughout study area. second uses very detailed topographic data set includes building height information integrated Digital Elevation Model (DEM); and third model utilizes different coefficients, depending type land use percentage occupancy each grid cell. These...
This paper quantitatively evaluates the suitability of multi-sensor remote sensing to assess seismic vulnerability buildings for example city Padang, Indonesia. Features are derived from data characterize urban environment and subsequently combined with in situ observations. Machine learning approaches deployed a sequential way identify meaningful sets features that suitable predict levels buildings. When assessing level according scoring method, overall mean absolute percentage error is...
In this letter, a new approach is proposed to classify tsunami-induced building damage into multiple classes using pre- and post-event high-resolution radar (TerraSAR-X) data. Buildings affected by the 2011 Tohoku earthquake tsunami were focus in developing method. synthetic aperture (SAR) data, buildings exhibit high backscattering caused double-bounce reflection layover. However, if are completely washed away or structurally destroyed tsunami, then might be reduced, SAR data will show...
Eastern Cape Province in South Africa has experienced extreme drought events during the last decade. In Africa, different land management systems exist belonging to two tenure classes: commercial large scale farming and communal small-scale subsistence farming. Communal lands are often reported be affected by degradation among others considered as trigger for this process. Against background, we analyzed vegetation response through assessing productivity trends monitoring intensity,...
The Sendai Framework for Disaster Risk Reduction (SFDRR) was adopted by 187 countries and offers a tangible agenda evidence-based policy disaster risk reduction as an integral part of the overall post-2015 global development agenda. progress implementation seven Global Targets at national level is tracked set 38 indicators. However, despite formal commitment, majority currently not in position to monitor Targets. lack information on disaster-related loss damage mainly due gaps data...
The paper presents an international multi-disciplinary initiative, a Namibia SensorWeb Pilot Project, that was created as testbed for evaluating and prototyping key technologies rapid acquisition distribution of data products decision support systems to monitor floods. Those include SensorWebs, Grids Computation Clouds. This pilot project aims at developing operational trans-boundary flood management system the Southern African region provide useful water-borne disease forecasting tools...
This paper describes tsunami disaster mitigation in the West Sumatra region with participatory technology assessment (pTA), which promotes direct interaction among member and experts to discuss issues reach consensus for through provision of information knowledge science technology. Two areas were examined: Padang, capital city; Painan city, a town southern Province, Indonesia. Tsunami have damaged these at least three times: 1797, 5–10-m-high wave height hit area; 1833, 3–4-m-high came;...
Abstract Carbon storage in soils is sensitive to changing climatic conditions, potentially increasing C fluxes from the atmosphere. This study provides an assessment of recent climate variability (1951–2000) and potential future (2001–2055) change impacts on soil for croplands German part Elbe River basin. Results indicate that recently (1991–2000) are a net source carbon (net annual flux 10.8 g m−2 year−1 atmosphere). The temperature trend years 1951–2000 (+0.8 K summer +1.4 winter mean...
Drought is one of the most severe natural disasters with a high risk for human livelihoods. Remote sensing based drought indices can identify dry periods using, e.g., precipitation or vegetation information. Besides frequency, duration, and intensity, timing onset duration are important variables to measure impact risk. This article classifies events on regard their production during different crop growing stages. nondrought seasons analyzed in Eastern Cape Province, South Africa. Here,...
