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.
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.
In Northern Europe, the initial effect of climate change was projected to increase crop yields. The 2019 European Environment Agency report "Climate change adaptation in the agricultural sector in Europe" again confirmed this. According to this 2019 report, projections indicate that yields of non-irrigated crops like wheat, corn and sugar beet ...
The coastal region of Bangladesh is especially prone to cyclones. [28] Between 1793 and 1996, there has been one cyclone about every 4.5 years. This has a detrimental effect on the local environment, as well as on families and their property. For instance, a cyclone that hit in 1970 caused 300,000 deaths and US$86.4 million of property damage. [28]
Climate change has forced many people in Bangladesh living in rural areas to migrate to cities that has caused a sharp rise in the slum population of Dhaka. [8] As Bangladesh is only less than 20 feet above sea level, there are fears and concerns that by the end of the 21st century, more than a quarter of the country will be inundated and 15 million people will be displaced due to sea level ...
The fact that climate change and temperature increases are expected to negatively affect crop yields in the tropics could have troublesome implications for poverty and food security, mainly because populations in the area are so dependent on agriculture as their only means of survival.
Indian agriculture (which accounts for 25% of the GDP and employs 70% of the population) is heavily dependent on the rains, for growing crops especially like cotton, rice, oilseeds and coarse grains. A delay of a few days in the arrival of the monsoon can badly affect the economy, as evidenced in the numerous droughts in India in the 1990s.
Bangladesh has an enormous excess of surface water during the summer monsoon (June to October) and relative scarcity towards the end of the dry season in April and May. . Internal renewable water resources are about 105 km 3 per year, while inflowing transboundary rivers provide another 1,100 km 3 annually (average 1977–2001)
