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. 

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.

Spend a day in Kathmandu, Nepal’s sprawling capital of four million people, and you’ll quickly notice what has long been a fact of life in this landlocked Himalayan country, and many other South Asian nations – no reliable electricity supply exists. Up to eight times a day, neighborhoods throughout the city suffer rolling power cuts due to load shedding, causing residents and businesses alike to either carry on in the darkness or rely on expensive, diesel-consuming generators to keep the lights on. Although the country’s civil war ended in 2006, carrying the promise of restored domestic stability and accelerated economic development, Nepal’s economy has remained hamstrung by an inconsistent energy supply, with only 40 percent of the population having access to electricity. This situation persists despite the fact that the country sits on top of a virtual goldmine – an estimated 80,000 megawatts (MW) of untapped hydroelectricity, of which it has harnessed a scant 700 MW.

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.

Devesh Kapur, Kishore Gawande, and Shanker Satyanath open their Center for Global Development working paper, “Renewable Resource Shocks and Conflict in India’s Maoist Belt,” with a crucial question: “Is there a causal relationship between shocks to renewable natural resources, such as agricultural and forest lands, and the intensity of conflict?” While the connection between the environment and conflict has been the focus of much study, Kapur et al. say that previous attempts have been plagued with “failure to address reverse causality and a failure to systematically control for alternative explanations for conflict.” Their report analyzes the relationship between the availability of resources and conflict by measuring rainfall, vegetation prevalence, and deaths due to the Maoist conflict in India. They find “a strong and substantively large relationship between adverse renewable resource shocks and the intensity of conflict,” and conclude that protecting the livelihoods of residents of the Maoist belt can help reduce violence. “Giving tribals greater access to forests and a range of forest products, whose consumption is the only available option during times of distress, can provide them with a critical self-insurance mechanism.”

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.

Historically, the concept of “water wars” – inter-state wars fought solely over water – has been fairly unsubstantiated. But continued population growth, accelerating development, and environmental changes are making water more scarce and in turn increasing the chances of related tensions and violence. To illustrate the growing role water plays in tensions around the world, Al Jazeera has put together a map linked to a series of stories they’ve done on water “flashpoints.”

Twenty-five years have passed since the Brundtland Commission first brought sustainable development to international prominence. Today, the United Nations appears on track to replace the soon-to-expire Millennium Development Goals with “Sustainable Development Goals,” marking the extent to which the international community has embraced the concept. And yet, in spite of its prominence, a specific and measureable definition of sustainability remains lacking.
