A special type of tree could facilitate peacebuilding in the Sahel. A stretch of semi-arid land south of the Sahara that runs from the Red Sea to the Atlantic Ocean through 10 countries (Eritrea, Sudan, Chad, Niger, Nigeria, Burkina Faso, Mali, Algeria, Mauritania, and Senegal). But the western subregion covering the Lake Chad area (the intersection of Chad, Cameroon, Nigeria, and Niger) and Liptako-Gourma (the tri-border zone of Burkina Faso, Mali, and Niger) in the Sahel has been the scene of a growing humanitarian crisis. Armed groups are terrorizing local populations. Rampant insecurity has forced 1 million people to flee their homes. People have been cut off from their livelihoods. Food insecurity is worsening. Casualties continue to mount. And climate change will likely exacerbate conditions, forcing more people to compete for depleted forest resources and land. More food shortages and instability will surely follow.

Mayibout 2 is not a healthy place. The 150 or so people who live in the village, which sits on the south bank of the Ivindo River, deep in the great Minkebe forest in northern Gabon, are used to occasional bouts of diseases such as malaria, dengue, yellow fever and sleeping sickness. Mostly they shrug them off.

Potential water wars due to plans for multiple dams, violent opium cartels supporting world heroin markets, and many conflict-financing minerals including everyday talc used for baby powder. These are the types of natural resources stories that usually make front page news about Afghanistan. But natural resources have a significant role to play in stabilizing Afghanistan. Instead of being a source of conflict, they may help with peacebuilding by creating livelihoods and creating opportunities for ex-combatants.

China is one of the “thirstiest” countries in the world with a per capita water availability a quarter of the United States. With population, pollution, and water shortages growing unabatedly, reclaimed water (e.g., treating wastewater to drinking water standards) could be the answer to China’s water insecurity. In China, extensive research in the 1980s into water reclamation and urban investments supporting infrastructure in the 2000s sparked production capacity in the country to rise from 63 billion gallons a day to 236 billion gallons per day between 2009 to 2015. Today, however, reclaimed water is a mere drop in the bucket meeting less than 1 percent of total urban water use. China could look to the tiny Southeast Asian city-state of Singapore to learn how it tapped reclaimed water to turn its water-scarce tiny island into a high-tech hydrohub. 

Safe water, sanitation, and hygiene (WASH) are vital for human well-being. However, 1 in 3 people (approximately 2.2 billion) still lack safe drinking water, 4.2 billion do not have access to safely managed sanitation services, and 829,000 people die annually from unsafe water and related sanitation and hygiene around the world.
