Climate change in Bangladesh is expected to have an impact on the Dhaka River System water quality, with increased monsoon flows and lower summer flows. However, these changes will not greatly affect the extremes of water quality to any great extent due to the overwhelming impact of pollutant discharges into the system.
Bangladesh is known for its vulnerability to climate change and more specifically to natural disasters. It is important to mention the fact that the location of the country is vulnerable for the presence for three powerful rivers, Asian rivers, Brahmaputra, Ganges and the Meghna along with their numerous tributaries that could result massive floods.
Other challenges facing the sector include environmental issues: insecticides, water management challenges, pollution, and land degradation all effect the agricultural system in Bangladesh. Bangladesh is particularly vulnerable to climate change , with extreme weather and temperature changes significantly changing the conditions for growing food.
One problem for drinking water quality in Bangladesh is that water sources in the country have poor climate resilience. For that reason, water quality varies from one month to the next, and this is "based on rainfall, temperature and other climate phenomena which are expected to get more frequent and intense with climate change".

Change the way we think about water and agriculture. Rain should be viewed as the ultimate source of water to be managed, and agriculture as part of an agro-ecosystem that provides food but also delivers other environmental services, such as maintaining soil fertility. Fight poverty by improving access to agricultural water and its use.
The long-term viability of water supply systems poses a significant challenge as a result of water resource depletion, climate change, and population expansion. [2] Water is a necessity for all forms of life as well as industries on which humans are reliant, like technology development and agriculture.
Agriculture (including irrigation, livestock, and aquaculture) is by far the largest water consumer, accounting for 69% of annual water withdrawals globally. Agriculture's share of total water use is likely to fall in comparison with other sectors, but it will remain the largest user overall in terms of both withdrawal and consumption.
Bangladesh, being situated on the Brahmaputra River Delta (also known as the Ganges Delta) is a land of many rivers, and as a result is very prone to flooding.Due to being part of such a basin and being less than 5 meters above mean sea level, Bangladesh faces the cumulative effects of floods due to water flashing from nearby hills, the accumulation of the inflow of water from upstream ...
