Essay On Land Subsidence

915 Words4 Pages

1. Introduction
A number of areas in various ecosystems in Indonesia are now facing land subsidence. Jakarta, Semarang, Indragiri Hilir, and Siak are the area where the rate of land subsidence is excessive.

Population growth and intensive urban development in these areas accelerate groundwater extraction.

Land subsidence in Jakarta, Semarang, and Indragiri Hilir was triggered by natural and anthropogenic process. Compare to natural-induced subsidence, anthropogenic subsidence is faster (Meckel, 2008). Human activities as well as inappropriate landuse plan and disaster management design might accelerate land subsidence and widen the risks. Unwise policies and programs regulated by government moreover will increase land subsidence rate. Nowadays, there are, at least, three problems in land subsidence governance in Indonesia that are land subsidence is not the strategic disaster issue, lack of government attention in order to create the tools on dealing with the problems, and lack of community involvement in the process of managing land subsidence impacted areas.

A Brief Review Of Ken Wells Restoring The Wetlands

774 Words | 4 Pages

Many people have taken over different swamp areas and destroyed the land with their boats and even littered the land. All of these things can destroy the land, making it much weaker to hold, which then results in coastal land loss. An article “Mixed Sediment for Sustainable Ecosystem Restoration of Louisiana” by Khalil Syed and other authors, explains how human activity has affected the Louisiana coastal land. Although humans play a large role in effecting the landscapes, Khalil states “The fast-degrading coastal Louisiana needs frequent emplacement of sediment where the objective is not limited to ecosystem restoration only but most importantly to mitigate the pervasive land loss” (Syed). The fast land loss that Louisiana experiences each day is affected by human activities that do not take any part in making things better.
