With clarity, conscience, and courage, global-systems pioneer Jorgen Randers and his distinguished contributors map the forces that will shape the next four decades.

Forty years ago, The Limits to Growth study addressed the grand question of how humans would adapt to the physical limitations of planet Earth. It predicted that during the first half of the 21st century the ongoing growth in the human ecological footprint would stop-either through catastrophic "overshoot and collapse"-or through well-managed "peak and decline."

So, where are we now? And what does our future look like?  In the book 2052, Jorgen Randers, one of the coauthors of Limits to Growth, issues a progress report and makes a forecast for the next forty years. To do this, he asked dozens of experts to weigh in with their best predictions on how our economies, energy supplies, natural resources, climate, food, fisheries, militaries, political divisions, cities, psyches, and more will take shape in the coming decades. He then synthesized those scenarios into a global forecast of life as we will most likely know it in the years ahead.

The good news: we will see impressive advances in resource efficiency, and an increasing focus on human well-being rather than on per capita income growth. But this change might not come as we expect. Future growth in population and GDP, for instance, will be constrained in surprising ways-by rapid fertility decline as result of increased urbanization, productivity decline as a result of social unrest, and continuing poverty among the poorest 2 billion world citizens. Runaway global warming, too, is likely.

So, how do we prepare for the years ahead? With heart, fact, and wisdom, Randers guides us along a realistic path into the future and discusses what readers can do to ensure a better life for themselves and their children during the increasing turmoil of the next forty years.

Jorgen Randers is professor of climate strategy at the BI Norwegian Business School, where he works on climate issues and scenario analysis. He was previously president of BI and deputy director general of WWF International (World Wildlife Fund) in Switzerland. He lectures internationally on sustainable development and especially climate, and is a nonexecutive member of a number of corporate boards. He sits on the sustainability councils of British Telecom in the UK and the Dow Chemical Company in the United States. In 2006 he chaired the cabinet-appointed Commission on Low Greenhouse Gas Emissions, which reported on how Norway can cut its climate gas emissions by two-thirds by 2050. Randers has written numerous books and scientific papers, and was coauthor of The Limits to Growth in 1972, Beyond the Limits in 1992, Limits to Growth: The 30-Year Update in 2004, and 2052: A Global Forecast for the Next Forty Years in 2011. Randers lives in Oslo, Norway.
