The book Dhaka Megacity: Geospatial Perspectives on Urbanisation, Environment and Health presents the use of geospatial techniques to address a number of environmental issues, including land use change, climatic variability, urban sprawl, population density modelling, flooding, environmental health, water quality, energy resources, urban growth modelling, infectious diseases and the quality of life. Although the work is focused on the Megacity of Dhaka in Bangladesh, the techniques and methods that are used to research these issues can be utilized in any other areas where rapid population growth coupled with unplanned urbanization is leading to environmental degradation. The book is useful for people working in the area of Geospatial Science, Urban Geography, Environmental Management and International Development. Since the chapters in the book cover a range of environmental issues, this book describes useful tools for assisting informed decision making, particularly in developing countries.

A unique strategic opportunity beckons Bangladesh. Dhaka, the economic powerhouse of the country, stands on the cusp of a dramatic transformation that could make it much more prosperous and livable. Today, Dhaka is prone to flooding, congestion, and messiness, to a point that is clogging its growth. But toward its east, where two major highway corridors will one day intersect, is a vast expanse of largely rural land. And much of it is within 6 kilometers of the most valuable parts of the city. The time to make the most of this eastward opportunity is now. Many parts of East Dhaka are already being developed in a haphazard way at an alarmingly rapid pace. Private developers are buying land and filling it with sand so they can build and sell new houses and apartments. Canals and ponds are disappearing, and the few narrow roads crossing the area are being encroached by construction. This spontaneous development could soon make East Dhaka look like the messy western part of the city, and retrofitting it later will be more difficult and costlier than properly planning and developing it now. Toward Great Dhaka: A New Urban Development Paradigm Eastward seeks to analyze how the opportunity of East Dhaka could be realized. Using state-of-the-art modeling techniques, the study simulates population, housing, economic activity, and commuting times across the 266 unions that constitute Greater Dhaka. It does so under various scenarios for the development of East Dhaka, but always assessing the implications for the entire city. The simulations suggest that pursuing a strategic approach to the development of East Dhaka would make Greater Dhaka a much more productive and livable city than continuing with business as usual. Based on current trends, Greater Dhaka would have a population of 25 million in 2035 and an income per capita of US$8,000 at 2015 prices. However, embracing a strategic approach would add 5 million people to the city. And, it would be a more productive city, with nearly 1.8 million more jobs and an income per capita of more than US$9,200 at 2015 prices, enough to put Dhaka on the map of global cities.

Between 1991 and 2010, Dhaka’s population more than doubled to 15 million. Simultaneously, the city’s contribution to the national economy almost trebled. Clearly, population growth was accompanied by an unmistakable trend of economic growth, and a significant decline in urban poverty and income inequality. On the other hand, Dhaka’s high population density exacerbated serious environmental challenges, and it was soon ranked as one of the world’s least livable cities. In the context of these contradictory signals of rapid urbanization, Dhaka’s Changing Landscape sets to answer three most intriguing questions: Are the poorer segments of urban population, which migrate with dreams for better lives, benefitting from positive economic trends? Are these benefits sustainable? Are these benefits creating scope for this group to have a stake in the city’s growing prosperity? By studying 600 households and applying comparative analysis over a span of 20 years, the authors examine demographic and economic trends to understand the patterns, scale, and complexity of urban poverty, income inequality, and rural–urban migration. Going beyond the space and poverty debate, they enlighten the readers about the quality of life questions, sustainability matters, and gender and generational roles and relations necessary to understand qualitative transformation and migrants’ prospects for a better future.
