Foreign Policy’s Elizabeth Dickinson recently sat down with UN High Commissioner for Refugees António Guterres for a wide-ranging interview on the global refugee crisis. Yet a strong theme emerges across the continents: The complexity of today’s conflicts belies either easy or quick solutions.

Worldfocus recently featured two pieces on the Arab world’s burgeoning population. “Demographics of the Arab World,” a radio broadcast, brings together Magda Abu-Fadil of the American University in Beirut and Bernard Haykel of Princeton University for a look at the region’s demographic trends. Despite possessing different political systems and being at different levels of economic development, demographic challenges of youth bulges, emigration, and gender gaps are common to countries across the Arab world. “Arab World Experiences Rapid Population Explosion,” a written interview with demographer Patrick Gerland of the United Nations Population Division, tackles similar issues. Topics of discussion include demographic variations between Middle Eastern nations, fertility rates, the consequences of the region’s youth bulge, and best- and worst-case scenarios for the Arab world’s future.

The journal Nature Geoscience recently published a study comparing the impacts of rural and urban population growth on deforestation. “Deforestation Driven by Urban Population Growth and Agricultural Trade in the Twenty-First Century” finds deforestation is positively correlated with urban population growth and agricultural exports to international markets. In rural areas, however, the link between deforestation and population growth was absent, indicating that urbanization and agricultural export-oriented economies were the primary drivers for forest loss. The study concludes that, rather than focusing on the activities of rural populations, deforestation reduction efforts should target “industrial-scale, export-oriented agricultural production, concomitant with efforts to increase yields in non-forested lands.” (SUBSCRIPTION ONLY)

For students, looking at national security through the lens of demography can be challenging and frustrating, says Jennifer Dabbs Sciubba, a Mellon Environmental Fellow and professor at Rhodes College. “You really have to start at the beginning and explain the fundamentals of, ‘What is population in the first place?’” she told ECSP Director Geoff Dabelko of her undergraduate courses on population-environment and population-security connections.

Two articles in the Sunday New York Times revealed that some residents of Mexico City and Charleston, West Virginia, share a common bond: lack of clean water. While drought and leaks have drained Mexico City’s reservoirs, pollution and run-off from coal plants has befouled water supplies in West Virginia’s small towns. But in both cases, the less powerful are the ones stuck up the creek without a paddle.

On Monday, California became the first U.S. state to issue a report outlining strategies for adapting to climate change. Among other recommendations, it suggests that Californians should consider moving.

Three people died in the city of Bhopal, in north-central India, in a battle between neighbors for scarce water, The Guardian reported this past week. Fights regularly broke out when the water tankers that serve 100,000 of the city’s residents make their deliveries.

The monsoon this year produced less rain than usual, exacerbating a drought. In addition, the number of people in Bhopal’s slums is growing. “The population has increased, but the water supply is the same,” a local committee chairman told The Guardian.

The northern parts of India were hardest hit, but much of India experienced similar conditions, including the city of Mumbai. Officials there cut water supplies for the city by 30 percent when the levels of the five lakes that serve as Mumbai’s primary sources of water dropped dangerously low.

But while heavy rains in the last few days mostly restored supplies, they also shut down the waterlogged city, reviving fears of 2005’s deadly floods. According to a new book and exhibit by University of Pennsylvania architects, the sprawling city has paved over the mangrove wetlands that protect it from flooding.

Pollution, climate change, population growth, urbanization, and industrialization in the world’s developing countries continue to increase demand for its finite water supplies. Today, 700 million people live in countries experiencing water scarcity or stress; by 2035, that figure is expected to have reached 3 billion people, or almost half of the world’s population. Asia, with 60% of the world’s population but only 36% of the world’s freshwater, will be particularly hard hit.

The problems vary across South Asia. The rivers around Dhaka, Bangladesh, are so polluted from industrial dumping that specialists are saying the situation is beyond repair. Lack of access to clean water and knowledge about hygienic sanitation practices leads to thousands of preventable deaths from diarrhea every year in Nepal. In Karachi, Pakistan, stealing public water out of pipes and tankers is a $500 million industry, “a mark of the state’s decreasing capacity to provide for its own,” reports Bill Wheeler in a special report in GOOD magazine.

The Indus Waters Treaty of 1960 between India and Pakistan has long been hailed as an example of the cooperation that can result from the necessity of sharing such an essential resource across borders. But with climate change causing the Himalayan glaciers that feed the Indus River to melt at a faster pace, some experts warn that balancing the water needs of both countries across their contested border could be a trigger point for conflict—particularly for two nations that cannot provide many of their citizens with access to safe drinking water under normal circumstances.

South Asian governments will be called upon more and more to balance the water of needs between different users at the local level and work with other governments to share and conserve water at the international level. But as Ashok Jaitly of New Delhi’s Energy and Resources Institute told Wheeler, both India and Pakistan share a “mentality that obscures the need to manage demand with conservation, water tariffs, and an end to destructive but politically popular practices in both countries.”

Despite the recognition of water as a growing security issue by the international community, it is difficult to improve what is a symptom of deeper-set problems. But they must try, if only for their own security. As Pakistan President Asif Ali Zardari warned in a Washington Post op-ed, “The water crisis in Pakistan is directly linked to relations with India. Resolution could prevent an environmental catastrophe in South Asia, but failure to do so could fuel the fires of discontent that lead to extremism and terrorism.”

“The breakdown of ecosystem-dependent livelihoods is likely to remain the premier driver of long-term migration during the next two to three decades,” says In Search of Shelter: Mapping the Effects of Climate Change on Human Migration and Displacement, a report launched at the recent international climate negotiations in Bonn.

According to the report, climate change will threaten livelihoods (and could consequently drive migration) through its impact on agriculture, glacial melt, sea-level rise, and the severity and frequency of natural disasters. While the report recognizes that migration is a complex issue involving a “combination of environmental, economic, social and/or political factors,” it stresses the impact of environmental change on “livelihoods which are dependent on ecosystem services, such as agriculture, herding, and fishing.”

Key to the report’s findings is the disproportionate effect that climate change will continue to have on developing countries, which are ill-equipped to adapt to climate change, and where many people’s livelihoods depend directly on ecosystem services. The report calls for the reduction of carbon emissions to mitigate climate change; the promotion of technologies that will enable adaptation; and the active participation of women and other marginalized groups in adaptation planning.

In a recent invitation-only meeting hosted by the Wilson Center’s Environmental Change and Security Program, Jon Barnett of the University of Melbourne suggested that migration that is partially due to climate might be an opportunity, as “you could use migration to facilitate adaptation.” In Search of Shelter also recognizes this potential opportunity, and suggests that development strategies be formulated accordingly. Better infrastructure, health care, and education in likely receiving cities—many of which are in the developing world and are already overwhelmed by burgeoning slum populations—would significantly reduce the pressure of migration on both migrants and receiving populations.

In Search of Shelter is a unique contribution to the field, examining climate change’s impact on migration in a careful, evidence-based manner. Yet it strikes a common chord with general reports on development by stressing the important role that access to health care, education, and infrastructure play in supporting healthy, secure populations. It may be up for debate how large of a role climate change will play in prompting migration, but it is clear that we need to integrate this issue into broader development, health, and governance strategies.
