The implications of population growth and climate change on sustainable development in Bangladesh

Abstract

Bangladesh is characterised by its large population on a small land, rapid and unplanned urbanisation, rising urban inequalities, food and nutritional insecurity and lower level of resilience to climate change. These combined effects are major threats to food security of the country in the near future. This paper examined the implications of population growth and climate change on sustainable development of Bangladesh. This research was based on the analysis of chronological data and synthesis of literature on population growth, greenhouse gases emission, climate change, food security and sustainable development, mainly contextualised on Bangladesh. The analysis found that the population of Bangladesh has almost doubled between 1980 and 2015. The country shared around 2.2% (in 2013) of global population and contributed only 0.19% of global carbon dioxide emission. On the contrary, climate change is the biggest challenge for the country. An increase in temperature could decline rice and wheat production. Moreover, average monsoon rainfall would be increased as a result of increased temperature. The increase in temperature and rainfall may lead to early arrival and late departure of the monsoon season or an increase in mean daily rainfall intensity. Population growth and climate change have multiple implications on development. Therefore, sustainable development may be difficult to attain if climate change continues to jeopardise economic growth, environmental stability as well as the social progress of Bangladesh.

Evaluating and Predicting the Effects of Land Use Changes on Hydrology in Wami River Basin, Tanzania

“…Despite relatively small changes in runoff generation due to the land use change, the findings suggest that increasing cultivated land and the built-up area in the Wami River Basin can cause severe threats in the future [55]. This will be more complicated with the current rapid population growth, climate change and economic growth within the basin [99]. The results can be used to identify and prioritize the implementation of best management practices in the most vulnerable areas to protect the natural resource in the basin [100].…”

Nipah Virus: Past Outbreaks and Future Containment

“…The region represents only 5% of global landmass but contrastingly accounts for 26% of the world's population. The world's densest urban area happens to be in Bangladesh [70] whereas Kerala, the south Indian state, is considered among the most densely populated states in India. Population density also accounts for the high rate of interaction among individuals and between environments.…”

“…Mondal [17] examined the implications of population growth and climate change on the sustainable development of Bangladesh using an exploratory research design. According to the study, the population of Bangladesh almost doubled between 1980 and 2015.…”
