Gains in food production and increased awareness of global food security are threatened by looming losses due to climate change, according to a study published in The Lancet. Marco Springmann et al. calculate that climate change will lead to a 3.2 percent reduction in global food availability per person by 2050, driven by changes in weather patterns, increasing frequency of extreme weather, and potential social disruptions to food production like disease and conflict.

It used to be a luxury to talk about the environment when you were addressing conflict. Today, “we recognize it’s not a luxury anymore,” said Liz Hume, senior director for programs at the Alliance for Peacebuilding, at the Wilson Center on April 29. Similarly, gender dynamics are now being recognized as playing a critical role in sustainable development and peacebuilding. [Video Below]

How will the 10 billion people expected to be living on Earth by 2050 obtain sufficient and nutritious food? This is one of the greatest challenges humanity faces. Global food systems must supply enough calories and protein for a growing human population and provide important micronutrients such as iron, zinc, omega-3 fatty acids, and vitamins.

Climate change is expected to affect rural to urban migration and Omar O. Chisari and Sebastian Miller, in a recently released working paper by the Inter-American Development Bank, analyze the various policy options available in two cases: domestic migration to São Paulo, and international migration from Bolivia and Paraguay to Argentina. Migration into cities will impact climate change mitigation strategies.

As early as 1911, coal miners in Britain carried caged canaries into mining pits. Any sign of distress from the small birds, which are incredibly sensitive to the presence of harmful gases such as carbon monoxide, meant immediate evacuation. Today’s canaries in the coal mine are low-income, minority communities whose exposure to environmental risks in the United States and elsewhere puts them at the frontlines of the global climate crisis.

Anyone visiting Singapore, as I did recently, quickly realizes it is exceptional. A tiny, rich, stable city-state of nearly 6 million people perched uneasily in a region of sprawling mega-countries full of poverty and instability, it also a thriving free market trading and financial center that is meticulously planned and where 80 percent of people live in public housing.

A report by the European Union on global food security finds 240 million people are in food stress thanks to conflict, refugee situations, flooding, drought, and El Niño. Part of a 2012 commitment by the EU to better target the root causes of food insecurity, the report analyzes the hunger situation in 70 countries and provides deeper analysis for 20.

Population, reproductive health, and environmental sustainability are inextricably linked. Growing populations place increasing demands on the environment, while meeting the reproductive health needs of populations usually slows their growth. Often, however, policymakers, scholars, and journalists discuss these issues separately, as if unrelated.
