This book broadens and deepens understanding of a wide range of population to climate change linkages. Incorporating population dynamics into research, policymaking and advocacy around climate change is critical for understanding trajectory of global greenhouse gas emissions, for developing and implementing adaptation plans and thus for global and national efforts to curtail this threat. The papers in this volume provide a substantive and methodological guide to the current state of knowledge on issues such as population growth and size and emissions, population vulnerability and adaptation linked to health, gender disparities and children, migration and urbanisation, and the data and analytical needs for the next stages of policy-relevant research.
