World population continues its steady climb, surpassing 7 billion in 2011 and heading to somewhere between 8 and 11 billion by midcentury. But funding to address population-related issues is moving in the opposite direction.

Evaluation is the lifeblood of any development effort – it’s how implementers know if they’re making a difference, determine what to do more or less of, and enables funders to evaluate cost-effectiveness. But it’s also an inexact science, no more so than when it comes to complex interventions that cut across sectors. [Video Below]

Half the world’s pigs – 476 million – reside in China. Increasingly prosperous consumers are eating fewer grains and demanding a more protein-rich diet, ballooning the pork industry to 15 times its 1960s-era size. In the last 30 years, Chinese demand for meat has quadrupled and China is now the largest consumer of seafood in the world.

In a world faced with rising temperatures, increasingly severe droughts and floods, and a rapidly growing population, how can people adapt to this new way of life – and even thrive? Leading experts discussed this question in-depth during an Aspen Institute Global Health and Development Program event titled, “Building Resiliency: The Importance of Food Security and Population.” The panel took place as part of the Civil Society Policy Forum at the 2014 IMF/World Bank Spring Meetings in Washington, DC.

Resilience means different things to different people. For many in the international development and humanitarian communities, building resilience means responding to growing climate risks through disaster mitigation and planning. But for people like Birhani Fakadi, a 39-year old mother of 11 in rural Ethiopia, it also means access to reproductive health and family planning services, says ECSP’s Roger-Mark De Souza in this week’s podcast.

What is the future of population and climate change research, and how can this research impact international policy? In a special issue of Population and Environment, environmental and social scientists look at these questions. “One of the most exciting developments in the climate change research community at present is the development of a new generation of climate scenarios,” write Adrian C. Hayes and Susana B. Adamo in the introduction. These can help facilitate more interdisciplinary research.

“Saving the planet depends on women achieving full human rights, and that begins with reproductive rights,” writes the Natural Resources Defense Council’s Frances Beinecke in a new set of essays on reproductive health published by the United Nations Foundation and the Aspen Institute.

Democracy is fickle. Many of the competing theories on the best ways to foment and consolidate plural, inclusive governance or predict its rise and fall focus on political and economic forces. Yet a small group of demographers have explored population age structure as a catalyst for and reflection of a host of changes in societies that can affect governance.
