“…Aside from the direct impacts, such as the damage of infrastructure and construction [31] [32], land subsidence has other negative impacts, such as salinization of coastal areas [33] [34], degradation of groundwater and changes to the water system [35]. Land subsidence triggers direct economic loss and external cost incurred in the effort to rehabilitate damaged construction, infrastructure and farmland [36] [37].…”

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.

“…Mikhailov and Dotsenko (2007) reported that the RSLR in the sea exposed part of this delta is 10 to 20 mm/y. Ericson et al (2006) also reported that the subsidence rate, as high as 25 mm/ y, results partially from groundwater extraction through shallow and deep tube wells (Alam, 1996;Haq, 1997). Though subsidence rates in excess of 25 mm/y might not be acceptable (Nicholls and Goodbred, 2005), many studies have reported such a magnitude mainly based on artefacts and tree stumps that are buried in the lower coastal plain.…”

“…The thickness of deltaic sediments overlying the oceanic crust in the central and eastern basin may reach up to 20 km. Long-term tectonic subsidence in the eastern and southern basin of 1-2 mm y-1 has been balanced by the high sediment supply from Himalayan erosion (Alam, 1996). The approximate transition of the Indian continent to oceanic crust, which acts as a hinge line, is marked by high gravity and magnetic anomalies (Iman and Shaw, 1985).…”

“…By the mid-Eocene the basin was witnessed the maximum marine transgression and most of the stable shelf was in carbonate regime as part of the extended Tethyan carbonate shelf. The deeper part of the basin was dominated by deep seafan sedimentation bed by clastic turbidities from the northern with limited carboniferous turbidities from the shelf (Alam, 1996).…”

The world's largest Ganga-Brahmaputra Delta has been characterized by an interesting and complicated tectonic background and geomorphic history. Actually the delta is situated in the southern part of Bengal Basin in Eastern India. The Bengal Basin as well as Ganga-Brahmaputra Delta, is a significant low flat terrain which has elevation of 10-30m above the m.s.l. Delta building processes are active over southern part, while the Northern part shows the characteristics of a mature landscape. The Delta is named as 'khadar'. The eastern part of Indo-gangetic plain is joined with the lower Brahmaputra plain and helps to form the delta. The delta has passed through a long evolutionary history and phases i.e. early Triassic, Jurrassic, Cretaceous, Oligocene, Miocene and Holocene. The Basin contains silt, clay, several minerals, metals etc. The delta is mainly created by the deposition after the sea-transgression in the upper cretaceous period. The mineralogy is dominated by detrital quartz, some feldspar and minor amounts of carbonates illite and kaolinite. Therefore its geological setup and the tectonic events and their influence on the geomorphic features particularly the flood-plain have been thoroughly investigated and presented in this paper.
