The impact of climate change, population growth and development on sustainable water security in Bangladesh to 2100

Abstract

There are concerns that groundwater use for irrigation and for urban water supply is unsustainable in some parts of Bangladesh, particularly in the agriculturally productive northwest region. We use an integrated population – GDP – food – water model to examine water demand to 2100 in Bangladesh in development scenarios relevant to food and water security. The results indicate that irrigation water demand is projected to increase in coming decades, but later in the century it may decrease due to increasing crop yields and a falling population. The increased demand is greatest in the northwest region and, if unchecked, would increase concerns there about the unsustainable use of groundwater. The growth in demand is determined particularly by growth in crop yields, population growth and the fraction of food demand satisfied by imports. An extreme hot-dry climate change scenario has a lesser impact. This suggests that, in principle, Bangladesh can offset the impacts of climate change on irrigation water demand through its domestic policies. Urban water use currently also leads to concerns over unsustainable groundwater use. Our results suggest that urban water demand is likely to grow proportionately significantly more than irrigation water demand. Alternative sources for urban water are therefore urgently required.

Green Financing as a Tool to Mitigate Climate Change for Sustainable Development: An Insight form Egypt

“…The result is aligned with the expectation about population growth in Egypt, as it is well above natural birth replacement levels and is expected to double by 2078 23 . The current finding could make a contribution to the existing body of literature, alongside the contributions made by Bellon and Massetti (2022), Kirby and Mainuddin (2022), Budolfson and Spears (2020), Dodson et al (2020), Nugent (2019), Scovronick et al (2017), UNFPA (2011) and Satterthwaite (2009).…”

“…Concurrently, the population of Bangladesh and West Bengal is expected to grow at least up to 2050. The growing population and economic development will increase demand and competition for water resources, exacerbating an already difficult position (Kirby and Mainuddin, 2022).…”

Explore the Climate Change Impact Scenario of Urban Cities in Bangladesh: A Qualitative Approach

“…Bangladesh can offset the influences of climate change on irrigation water demand through its local policies. Urban water use presently also indications to concerns over unmanageable groundwater use (Mac and Mainuddin, 2022). Bangladesh is an emerging country in South Asia that had an urban inhabitants of 60 million populaces in 2018, although its rate of urbanization (1.40) was lower than that of lower-middle-income countries.…”

“…There are concerns that groundwater use for irrigation and for urban water supply is unsustainable in some parts of Bangladesh, particularly in the agriculturally productive northwest region. Promote safe recycle of treated wastewater for irrigation, industry, and secondary domestic purposes (Mac and Mainuddin et al, 2022). Every year, residents of the Barishal slum challenge a diversity of climate hazards.…”
