The planet Earth is faced with one of the gravest threats of our time–climate change, which puts in peril all our efforts to promote sustainable development and compels us to look for ways to combat this menace. This is the backdrop that dictates the thematic construct of this book. The second installment of a series of anthologies of write-ups by eminent economist Dr Qazi Kholiquzzaman Ahmad on various issues of socio-economic development, this book is a compilation of 21 articles and 12 power-point presentations, written over a span of two decades and a half. The commentaries here deal with the persisting issues regarding environment, climate change and water, which are entwined on various fronts and one of them cannot be really separated from the rest as far as the vast canvas of survival and development of the humankind, even of the planet Earth is concerned. The write-ups on environment and climate change deal with a range of issues including poverty, livelihood, and environmental balance; environmental protection; climate change, flood, and flood management; climate change mitigation and adaptation with particular focus on Bangladesh, the Asian region, the milestones of global efforts in combating climate change, etc. And the pieces on water resources discuss topics like integrated river basin management in the Ganges-Brahmaputra-Meghna (GBM) region, Bangladesh Water Vision 2025, water management with special reference to South Asia, addressing poverty through water action, flood management and local adaptation strategies, Indo-Bangladesh cooperation on transboundary rivers and so on. There is also an article on energy, a key issue in climate change and in the context of sustainable development. Interestingly, though the world adopted the Sustainable Development Goals only in 2015, Dr Ahmad had been writing on the importance and nature of such ambitions since the 1980s. This book provides a comprehensive picture of environment, climate change, and water-relate
