The Philippines faces a breadth of social and environmental challenges that threaten its economic and political stability. A long history of violent conflict stemming from ethnic, religious, and political tensions is further complicated by changing weather patterns that cause severe drought and damaging storms. Millions of people in Mindanao have been displaced by violence and extreme weather events, and their migration from rural areas leaves room for the expansion of terrorist groups that threaten regional stability. The United States currently has strong trade and cultural ties to the Philippines, and U.S. Pacific Command operates military facilities on the islands. This chapter examines the stakes for U.S. interests in Mindanao, and recommends a security approach that combines defense, diplomacy, and development efforts to promote improved governance, social stability, and climate resilience.

Earlier this month 46 House Republicans voted with Democrats to protect an amendment in the current National Defense Authorization Act that acknowledges that “climate change is a direct threat to the national security of the United States” and requires the secretary of defense to provide “a report on the vulnerability to military installations and combatant command requirements resulting from climate change over the next 20 years.”

Capable of upending rural livelihoods, compromising institutions of governance, and inducing new patterns of migration and crime, global water stress has emerged as one of the principal threats to U.S. national security, said David Reed, senior policy advisor at the World Wildlife Fund (WWF) and editor of WWF’s new book, Water, Security and U.S. Foreign Policy, on June 27 at the Wilson Center. Four defense and development leaders – retired U.S. Marine Corps General James L. Jones; Paula Dobrianksy, vice chairwoman of the National Executive Committee of the U.S. Water Partnership; retired U.S. Navy Admiral Lee Gunn, vice chairman of the CNA Military Advisory Board; and Kristalina Georgieva, chief executive of the World Bank – joined Reed for a panel discussion of water’s central role in global stability and prosperity.

“If we really cared about the polar bears, we would have done something,” quipped retired U.S. Navy Rear Admiral David Titley, who gave an Environmental Research and Education Distinguished Lecture at the National Science Foundation on June 27, 2017. Titley framed climate change in terms of U.S. national security interests, focusing on infrastructure, the changing Arctic, and how environmental factors can exacerbate conflict.

Climate change, civil conflict, and violent extremism are among the most significant threats to human development, peace, and security around the globe. Addressing all three requires immediate action by the United Nations to prevent future crises, yet crucial investments may not yield tangible results for years to come—well beyond democratic term limits.

Water, water everywhere but not a drop to drink: All five of the most popular posts last month focused on water scarcity.

The final two parts of our “Choke Point: Tamil Nadu” series, which explores the conflicting demands for water, food, and energy in the South Indian state, took the top spots. In June’s most popular post, Circle of Blue’s Keith Schneider reports on Tamil Nadu’s leadership in India’s transition to solar and wind energy, which use far less of the country’s scarce water resources than coal and nuclear power plants. Schneider also wrote “New Media Helps Galvanize Tamil Nadu to Fight a Toxic Legacy,” which describes an environmental activist’s fight against industrial water contamination.

U.S. prosperity and national security depend directly on the prosperity and stability of our partner countries and competing countries around the world. Today, water-driven stresses are, with increasing frequency, undermining economic productivity, weakening governance systems, and fraying social cohesion. Water scarcity has created a context of human and societal need wherein water stress has undermined the vitality of rural livelihoods, driven broad migratory movements, become a weapon of war, contributed to the growth of insurgencies and terrorist networks, and given rise to increased demand for U.S. development, humanitarian, and military assistance.
