'''Natural hazards:'''
Much of the country is submerged by floodwater in the monsoon season (and traditional settlements and agriculture are adapted to this); damaging floods occur when rivers rise higher than normal; tropical cyclones (hurricanes) and storm surges; droughts; riverbank erosion along the country's major rivers and in the Meghna estuary; earthquakes; possibly tsunamis.<ref>{{Cite journal |last=Sasidhar |first=Nallapaneni |date=May 2023 |title=Multipurpose Freshwater Coastal Reservoirs and Their Role in Mitigating Climate Change |url=https://www.ijee.latticescipub.com/wp-content/uploads/papers/v3i1/A1842053123.pdf |access-date=2023-06-05 |journal=Indian Journal of Environment Engineering |issn=2582-9289 |volume=3 |issue=1 |pages=31–46 |doi=10.54105/ijee.A1842.053123 |s2cid=258753397 |archive-date=11 June 2023 |archive-url=https://web.archive.org/web/20230611114313/https://www.ijee.latticescipub.com/wp-content/uploads/papers/v3i1/A1842053123.pdf |url-status=live}}</ref>

'''Environment – current issues:'''
Country very densely populated (1,125 per km<sup>2</sup>); rapid urbanisation taking place; many people landless, and many live on and cultivate land exposed to floods, riverbank erosion or cyclones; groundwater used for drinking water and irrigation is widely contaminated with naturally-occurring arsenic in some floodplain areas; water-borne diseases prevalent; surface water widely polluted by industrial, agricultural and urban effluents, affecting domestic supplies and inland fisheries; intermittent water shortages because of falling water tables in some northern and central parts of the country; increasing water and [[soil salinity]] in some coastal areas, especially in the south-west, due to abstraction of river and groundwater upstream; [[soil retrogression and degradation|soil degradation]] due to intensive cropping, depletion of organic matter and unbalanced use of fertilisers; deforestation and soil erosion in hill areas.
