In recent weeks, militants in Pakistan have escalated their hostile rhetoric toward India. The subject of their ire is water. Hafiz Saeed, the head of militant Islamist group Jamaat-ud-Dawa, has warned that India plans “to make Pakistan barren” by preventing the waters of the Indus Basin from flowing downstream to Pakistan. 

When French peasants stormed the Bastille on July 14, 1789, they weren’t just revolting against the monarchy’s policies. They were also hungry.

In 2011, a record 34 billion cubic tons of carbon dioxide were emitted from man-made sources. Half the emitted CO₂ stays in the atmosphere, about a quarter is absorbed on land (as trees grow, for example), and the remainder is absorbed by the ocean. Unsurprisingly, this incredible amount of carbon dioxide significantly changes the ocean environment. Over time, increased absorption of carbon dioxide in the oceans has led to ocean acidification, and overall warming has also led to warming of ocean waters – both changes impact marine ecosystems and the people who rely on them.

The water-energy-food nexus seems to be garnering more and more attention in the media and elsewhere, and it’s easy to see why: it’s a relatively simple way to illustrate how interconnected the world is today and the kind of domino-like effects that scarcity can have.

Eight years from now, the Gaza Strip will have “virtually no reliable access to sources of safe drinking water, standards of healthcare and education will have continued to decline, and the vision of affordable and reliable electricity for all will have become a distant memory for most,” according to a United Nations report released last month. The bleak assessment concludes that without immediate action to address immense and interconnected economic, demographic, environmental, infrastructure, and social challenges facing Gazans, “the already high number of poor, marginalized and food-insecure people depending on assistance will not have changed, and in all likelihood will have increased.”

Earlier this month, there was a flurry of stories about brutal mass killings in clashes between the Pokomo and Orma communities over water and land in southeast Kenya’s Tana River County. The Kenyan media reported that about 30 people, including eight security personnel, had been killed and scores wounded, and reports on the death toll since last month are more than 100.

Around the world, as the most easily accessible natural resources are depleted, states are beginning to turn to more remote reserves to meet their needs and the shift may spark international tensions or even conflict, said Hampshire College professor Michael Klare in a recent interview with ECSP. “I worry very much about this growing global competition for the remaining resources in those parts of the world,” he said.

Following the steady economic growth that many African countries have experienced in recent years and continued population growth, urbanization has accelerated rapidly on the continent as people turn to cities to take advantage of new economic opportunities. But growing cities have led to another problem. According to a new Food and Agriculture Organization (FAO) report, Growing Greener Cities in Africa, urban populations are exceeding the capacity of African cities to provide food for them, putting nearly 300 million people at risk of hunger and malnutrition, and greener strategies – urban agriculture and better water use – could help considerably.
