In addition to affecting the natural flora and fauna of regions of coastal Bangladesh, increased salinity could also affect the soil salinity, and therefore the agriculture output of the regions. This trend has already been seen in coastal regions like Satkhira, where the net area of cultivated land decreased by 7% from 1996 to 2008.
[2] [3] In the 2020 edition of Germanwatch's Climate Risk Index, it ranked seventh in the list of countries most affected by climate calamities during the period 1999–2018. [4] Bangladesh's vulnerability to the effects of climate change is due to a combination of geographical factors, such as its flat, low-lying, and delta-exposed topography.
Environmental impact of development in the Sundarbans, is the study of environmental impact on Sundarban, the largest single tract mangrove forest. [1] It consist of a geographical area of 9,629 square kilometres (3,718 sq mi), including 4,185 square kilometres (1,616 sq mi) of reserve forest land, and is a natural region located partly in southern Bangladesh and partly in the Indian state of ...
Morphological changes: the process of erosion and acceleration in the coastal area of Bangladesh between 1989 and 2018 [28] Bangladesh coastal areas are covering the south part of Bangladesh. The main rivers of Bangladesh derived from the Himalayas carry a high level of sediment and deposit it across the Bay of Bengal.
Sea level rise, flooding, sea wave erosion, and bank erosion impacting local water quality, resulting in a planned relocation 12 km (7.5 mi) from the present site. 2007 [28] [29] [30] Newtok: Bethel, Alaska, United States 209 Erosion due to melting permafrost and increasing flooding risk, requiring movement to Mertarvik. 2019 [31] [32] Shaktoolik
Additionally, the Mangroves species present in the Sundarban area serve a crucial function as a protective barrier for the millions of inhabitants in and around Kolkata, Khulna and Port of Mongla against the floods that result from the cyclones. It also protects from tsunami and soil erosion for the coastal population. [23]
An Ecologically Critical Area (ECA) is an environmental protection zone in Bangladesh. In 1995, specific areas in Bangladesh could be deemed Ecologically Critical Areas as a result of the Environmental Conservation Act. [1] Bangladesh has a wide variety of ecosystems that include over 300 rivers that creates marine and fresh water environments. [2]
[34] [35] There is growing evidence that tillage erosion is a major soil erosion process in agricultural lands, surpassing water and wind erosion in many fields all around the world, especially on sloping and hilly lands [36] [37] [38] A signature spatial pattern of soil erosion shown in many water erosion handbooks and pamphlets, the eroded ...
