Exploring the importance of megacities and megacity-regions as one of the defining features of the 21st century, this Handbook provides a clear and comprehensive overview of current thinking and debates from leading scholars in the field. Highlighting major current challenges and dimensions of megaurbanization, chapters form a thematic focus on governance, planning, history, and environmental and social issues, supported by case studies from every continent. Analysing vital questions for contemporary urban research, this Handbook looks at: what place megacities and megacity-regions occupy in a world of cities; how they interrogate current thinking about urban society, theory, and policy; and what role these largest of urban areas will play in shaping humanity's future. Key contributions reveal that research needs to further focus a critical and analytical lens on the particularities and distinctive issues associated with megaurbanization. A timely and essential read for urban studies, urban geography, and public policy students, the interdisciplinary nature of this Handbook provides a thorough view into the features and importance of megacities and megacity-regions. Public policy-makers and planners will also benefit from the wide-ranging case studies included.

Vietnam is in the midst of one of the world's most rapid and intensive rural-to-urban transitions. In Hanoi, heritage preservation has gained significant policy attention over the last decades, but efforts continue to focus on the Old Quarter and Colonial City to the exclusion of collective socialist housing complexes and former village areas, and natural features such as canals and urban lakes. Parks and public spaces are urgently needed to offset the high residential densities and to improve the quality of life of residents. Motor vehicles continue to fuel the growth in transportation. Significant efforts were recently made to establish a mass transit system, but progress there is slow. More attention should be paid to improving the existing transportation system and to reduce dependence on fossil fuels. Investments in new housing estates have fuelled a speculative real estate market but failed to address adequately the needs of the vulnerable segments of the population. Regional integration is a challenge as the city expands and swallows the peri-urban areas around the city.
