Preface The idea of this book triggered following a series of op-eds by Mohammad Zaman in the Financial Express, Dhaka (March–June 2019) on the plight of communities living in chars within the rivers of Bangladesh. Mustafa Alam, who earlier conducted extensive studies on chars under the aegis of the Flood Action Plan, followed up on the op-eds, suggesting we could together edit a book on the subject of chars in Bangladesh. We were both enthused by the idea and sent out a Call for Papers in June 2019, which received encouraging responses from many of our erstwhile colleagues and other professionals around the globe. It is gratifying to note that our initiative has brought together a multidisciplinary and global team of international and national experts, contributing chapters to the book on the diverse physical, environmental, socio-economic and institutional issues concerning chars in Bangladesh. We hope all this will prove valuable to academicians, policy planers and development practitioners alike. Looking back, compiling this volume was not an easy task. As editors, it was a challenge going through multiple levels of professional interaction with all so many authors, providing feedback on their drafts and pulling the net together at the end. This truly collaborative task was possible only because we received full and continuous support from all concerned in the entire process. We like to thank Jakia Akter and her Team at the Centre for Environmental and Geographic Information Services (CEGIS) in Dhaka for producing a number of maps used in the introductory part of the book. We also want to thank Dr. Robert Doe, Editor of the Springer Series in Geography/Human-Environment Research, and the Springer Production Team Lead Rajan Muthu and Ritu Chandwani for their understanding support. Sadly, Hugh Brammer (1925–2021), one important contributor to the volume, died of COVID-19 in January 2021. A geographer and a soil scientist of repute, he had a deep love for Bangladesh, which he considered his second home. He was advisor to the Food and Agriculture Organization (FAO)—Bangladesh. He will be remembered for his wisdom as well as his warmth and generosity. Our objective, and indeed, the driving force behind the book, has been to bring the isolated chars and char people into the forefront of development discourse in the ix x Preface country. We will consider our sincere effort in producing this volume a success only when this objective is met. Finally, our families and friends shouldered additional burdens in more ways than one during the stretch of time over which we prepared the manuscript of the book. We thank them all. Vancouver, B.C., Canada Mohammad Zaman Vancouver, B.C., Canada Mustafa Alam About This Book Panoramic view of charland in the dry season (source The Daily Star, Dhaka) In Bangladesh, the chars within the river channels are an important part of its land- scape. However, these land masses continue to remain isolated, deprived of services, and pockets of poverty in the country. The char dwellers are vulnerable to natural hazards like flood and erosion. In addition to these hazards, the coastal chars are faced with the imminent problem of widespread inundation due to sea level rise resulting from climate change. Within this context, the book Living on the Edge: Char Dwellers in Bangladesh has brought together valuable scholarship on the diverse issues relating to the chars and the communities living in there. This comprehensive collection, with contribution of experts on the subject from across the globe, provides an understanding of the xi xii About This Book problems faced by the char dwellers and also comes up with policy prescriptions for ensuring overall welfare of char communities in the country.
