“…However, with regard to land subsidence management, the DRM cycle, which was designed for a single shock disaster, appeared less suitable adoption. This is because land subsidence is characterized as a sleeping, or silent, disaster [6], which continuously happens over a long period and beyond a single phase of disaster management. As the impacts of the land subsidence are serious and will be worsening by the combination with climate change [44] [45], the public authorities and land users must select proper means to increase their capacity to adapt to the land subsidence.…”

“…In addition, the rapid population growth in Jakarta of about 136 thousand people per year triggers additional groundwater extraction, which in turn increases land subsidence [3] [4]. Semarang City experiences land subsidence of about 8 -11 centimeter per year [5], caused by a combination of alluvium soil consolidation, massive groundwater extraction and a heavy construction load [6] [7]. In both cases, the intensive growth of industrial areas, settlements and population, leads to increased demand for clean water extracted with confined aquifers, and accelerates land subsidence [3] [8].…”

Land subsidence can have a considerable impact on the socio-economic viability of areas. In urban areas, land subsidence tends to damage buildings and infrastructures gradually, while in rural peat land it slowly destroys vegetation. The damages will worsen since climate change has further implications for the areas affected by land subsidence. In Indonesia, the response to land subsidence varies in different areas in terms of awareness, urgency and action on the part of both public authorities and land users. This paper systematically investigates these varied responses in urban and rural peat land areas. Interviews with experts and surveys of 330 land users in selected sub-districts were conducted and further supplemented by focus group discussions. We found that both the public authorities as well as the land users' responses were considered as of limited value to contest land subsidence. We suggest that the endorsement of land users' response into governmental policies would make a significant difference in improving land subsidence management.

The detection of active movements that could threat the infrastructures and the population is one of the main priorities of the risk management chain. Interferometric Synthetic Aperture Radar (InSAR) techniques represent one of the most useful answers to this task; however, it is difficult to manage the huge amount of information derived from the interferometric analysis. In this work, we present a procedure for deriving impact assessment maps, over a regional test site, using as starting point Sentinel-1 SAR (Synthetic Aperture Radar) images and a catalogue of elements at risk that acts as a second input of the methodology. We applied the proposed approach, named as Vulnerable Elements Activity Maps (VEAM), to the islands of Gran Canaria, La Gomera and Tenerife (Spain), where we analysed SAR images covering the time interval November 2014-September 2016. The methodology, meant to be a powerful tool for reducing the time needed for a complete analysis of a full stack of InSAR data, is ideally suited for Civil Protection Authorities. The application of the methodology allowed to detect 108 areas affected by active deformation that are threatening one or more elements at risk in 25 municipalities of the three islands.

“…Ground subsidence caused by pumping up mass ground water in alluvial plains is one of the serious social problems of the present days in not only advanced countries but also developing countries (e.g., [1] [2]). Surely, ground subsidences caused by pumping up are almost partially limited by the regulation of the groundwater pumping in Japan already [3].…”
