The World Economic Forum recently named water crisis the world’s number one risk for the next 10 years for its potential impact on people and industry. Indeed, as the global community grapples with climate change – and environmental change of all kinds – understanding the fundamental nature if water to human society is crucial. The input report for this year’s World Water Week, released yesterday by the Stockholm International Water Institute, in fact argues that getting water management right is a prerequisite for sustainable development.

Karachi, the world’s second largest city by population, is emerging from the grips of a deadly heatwave. A persistent low pressure system camped over the Arabian Sea stifled ocean breezes and brought temperatures in excess of 113°F (45°C) to the city of 23 million people in June. The searing heat disrupted electricity and water service, making life nearly unbearable. All told, officials estimate the heatwave killed at least 1,200 Pakistanis, more than twice as many as have died in terrorist attacks this year.

“Tackling climate change could be the greatest global health opportunity of the 21^st century,” asserts the newest report by the Lancet Commission on Health and Climate Change.

In 2011 Thailand was hit by unprecedented monsoon rains far above the average rainfall of the previous 30 years. Two million people across 26 provinces were affected. During the crisis, hundreds of civilians took it to the streets to protest discrimination by the Flood Response Operation Center and the unfair distribution of water, electricity supply, shelter, and food. Civilians were so angry that they broke a sandbag wall in Bangkok which was protecting a wealthy district from water surges. Public unrest and discontent with the government continued until a military coup in 2013.

When the leaders of the G7 countries – Canada, France, Germany, Italy, Japan, the United Kingdom, and the United States – met earlier this month, they agreed to make fossil fuels a thing of the past by 2100. At the same time the G7 is also taking steps to make climate change’s connection to conflict a priority in the present.

The world is more connected than ever before, but also more complex. Big, transnational trends like climate change, urbanization, and migration are changing the calculus of geopolitics, while local-level inequalities persist. “[Change] seems to be spinning around us so fast,” said John Hempelmann, president of the Henry M. Jackson Foundation, which honors the legacy of the late senator from Washington State. How can today’s and tomorrow’s leaders adjust to global trends? [Video Below]
