Question

impact of flood in sundarban on human beings​

Answer 1

${\dag} \: {\underline{\boxed{\sf{\purple{ ANSWER }}}}}$

Regulating services can reduce people's exposure to natural hazards such as floods, fire and droughts. The Sundarbans World Heritage Site has been selected to highlight the important benefits that mangrove ecosystems deliver as a result of natural hazard regulation. Inhabiting estuaries and inter-tidal zones, mangroves provide vital ecological stability by delivering protection against erosion, providing buffer zones and reducing flooding– thereby contributing to coastal protection (Colette, 2007; FAO, 2014). It is anticipated that coastal zones, such as the Sundarbans, will become increasingly prone to natural disasters as the results of climate change intensify (Agrawala et al., 2003). Increased exposure to natural hazards amplify the vulnerability of World Heritage Sites by increasing the chances that key ecosystems, listed for having Outstanding Universal Value, will be changed, degraded or destroyed (UNESCO et al., 2010).

Answer 2

Explanation:

Sundarbans is the world's largest contiguous mangrove forest and is a designated world heritage site. Shared by India and Bangladesh, it is home to several species including tigers. The habitat supports approximately 4.37 million people. As per the research conducted it is believed that the Sundarbans have soaked in 4.15 crore tonnes of carbon dioxide. Due to climate change the Sundarbans faces several challenges. With rising sea levels, islands are disappearing and the increasing salinity in the water and soil has severely threatened the health of mangrove forests and the quality of soil and crops. Additionally, there have been serious disturbances to hydrological parameters and change in fishing patterns, resulting in disastrous consequences for fishermen. Frequent cyclones and erratic monsoon raining pattern are damaging ecology and humanity. In addition to general environment protection laws, India has also set up institutes at both the Central and State levels to specifically tackle the effects of climate change on Sundarbans.
