From Ukraine and the Middle East to sub-Saharan Africa and East Asia, the world is engulfed in a series of significant international crises. But despite such urgent issues, it would be a grave mistake to forget about the structural foreign policy challenges – such as access to water – that could become the crises of the future.

The effects of climate change “are here now” and pose a “serious challenge” for the United States, said Alice Hill, White House senior advisor for preparedness and resilience, at the Wilson Center on July 29. [Video Below]

Island communities, particularly those from small island developing states, are often reported in policy documents, academic papers and mainstream media as being “most vulnerable” to climate change and disasters. While such a classification might serve to raise awareness of their plight, or be used as impetus for global action, this approach can also result in unintended (and damaging) attitudes and consequences. This is well-illustrated by recent off-the-record discussions with several donors and policy-makers who have inappropriately implied it is “too late” to “save the islands,” given their vulnerability to current and impending climate change impacts.

In 1986, global nuclear weapons stockpiles peaked at nearly 70,000 warheads. By the beginning of 2013, there were just over 17,000, with only 4,400 kept operational. This dramatic reduction was the fruit of a negotiation process that began in the late 1940s. In spite of incredible tensions between the United States and the Soviet Union, negotiators were able to make progress once they focused on building trust with small, pragmatic steps, rather than starting with the complete elimination of all weapons. [Video Below]

A new law in Peru encouraging investment in the country’s extractive industries has reignited debate on the lack of power indigenous women have in the mostly rural societies where they often live. The International Indigenous Women’s Forum, which drew more than 60 native women from across the world to Peru last month, highlighted this important issue.

The time has come for us to collectively reexamine – and ultimately move past – the concept of sustainability. The continued invocation of sustainability in policy discussions ignores the emerging realities of the Anthropocene, which is creating a world characterized by extreme complexity, radical uncertainty, and unprecedented change. From a policy perspective, we must face the impossibility of even defining – let alone pursuing – a goal of “sustainability” in such a world. It’s not that sustainability is a bad idea. The question is whether the concept of sustainability is still useful as an environmental governance framework.
