This book broadens and deepens understanding of a wide range of population-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 urbanization; and the data and analytical needs for the next stages of policy-relevant research.

The report presents findings from the 2018 revision of World Urbanization Prospects, which contains the latest estimates of the urban and rural populations or areas from 1950 to 2018 and projections to 2050, as well as estimates of population size from 1950 to 2018 and projections to 2030 for all urban agglomerations with 300,000 inhabitants or more in 2018. The world urban population is at an all-time high, and the share of urban dwellers, is projected to represent two thirds of the global population in 2050. Continued urbanization will bring new opportunities and challenges for sustainable development.

The Population Situation Analysis (PSA) provides the basis for an integrated appraisal of the population and reproductive health dynamics and their impacts on poverty, inequality and development. By integrating a micro and macro analytical approach, the population situation analysis clarifies the interactions between individual behaviour and demographic dynamics. The Population Situation Analysis (PSA) responds to demand by countries that international cooperation should promote national capacity-building and recognize national ownership and leadership as prerequisites for development, in accordance with the principles agreed at the International Conference on Population and Development (ICPD) and the Millennium Declaration. This manual contributes to more efficient evidence-based programming, which relies on increased capacity for data generation, new databases, the consolidation of available evidence and the promotion of the use of hard data.
