As the world's population exceeds an incredible 6 billion people, governmentsâ€"and scientistsâ€"everywhere are concerned about the prospects for sustainable development. The science academies of the three most populous countries have joined forces in an unprecedented effort to understand the linkage between population growth and land-use change, and its implications for the future. By examining six sites ranging from agricultural to intensely urban to areas in transition, the multinational study panel asks how population growth and consumption directly cause land-use change, and explore the general nature of the forces driving the transformations. Growing Populations, Changing Landscapes explains how disparate government policies with unintended consequences and globalization effects that link local land-use changes to consumption patterns and labor policies in distant countries can be far more influential than simple numerical population increases. Recognizing the importance of these linkages can be a significant step toward more effective environmental management.

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.

There is long-standing debate on how population growth affects national economies. A new report from Population Matters examines the history of this debate and synthesizes current research on the topic. The authors, led by Harvard economist David Bloom, conclude that population age structure, more than size or growth per se, affects economic development, and that reducing high fertility can create opportunities for economic growth if the right kinds of educational, health, and labor-market policies are in place. The report also examines specific regions of the world and how their differing policy environments have affected the relationship between population change and economic development.

The United Nations population estimates and projections form a comprehensive set of demographic data to assess population trends at the global, regional and national levels. They are used in the calculation of many of the key development indicators commonly used by the United Nations system, including for more than one third of the indicators used to monitor progress towards the achievement of the Sustainable Development Goals. The 2019 revision of the World Population Prospects is the twenty-sixth edition of the official United Nations population estimates and projections, which have been prepared since 1951 by the Population Division of the Department of Economic and Social Affairs. The 2019 revision presents population estimates from 1950 until the present for 235 countries or areas, which have been developed through country-specific analyses of historical demographic trends. It builds on previous revisions by incorporating additional results from the 2010 and 2020 rounds of national population censuses as well as information from vital registration and recent nationally representative household sample surveys. The 2019 revision also presents population projections to the year 2100 that reflect a range of plausible outcomes at the global, regional and country levels. These Highlights summarise key population trends described by the estimates and projections presented in World Population Prospects 2019.

In preparation for the World Summit on Sustainable Development in September 2002 in Johannesburg, South Africa, [this book] evaluates what has been achieved since the 1992 Earth Summit in Rio. Ten years ago, the leaders of the world produced a plan to begin creating a sustainable global economy, one that meets human needs while protecting and restoring the natural environment. How much progress has the world made toward that goal? With [the book] as your guide, you will learn about the problems facing the delegates in Johannesburg as they try to answer this question -from today's severe inequalities of wealth and income (1.2 billion people live on 1 [dollar] a day or less) to environmental threats such as climate change, growing numbers of tourists in fragile areas, and the proliferation of toxic chemicals. The authors also shed light on the possibilities for change and how existing technologies and resources can help solve many of our most pressing problems. Using renewables like wind power, the energy economy can be converted from oil to hydrogen. Poor farmers can grow more food by taking advantage of "free" biological services, like nitrogen-fixing plants and beneficial insects. And women can have fewer children when they have a chance to get an education and to act on their own decisions on when to have children. [The book] spells out priorities for the Johannesburg Summit in seven key areas: agriculture, energy policy and climate change, chemicals, international tourism, population growth, resource-based conflicts, and global governance. Decisions made today can make all the difference in our efforts to build a more stable and secure world in the future.-- From back cover.
