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.

A significant increase in fisheries-related conflicts in the Indian Ocean since 2000 is heightening regional tensions. These conflicts have ranged from purely verbal and diplomatic disputes to armed attacks on fishing vessels by coast guards and navies. These disputes are most often low-intensity, but constitute true “wild card” scenarios in which competing powers’ navies reach the brink of engagement due to the actions of third parties that they neither command nor control.

The Amazon endured the most intense fire season in almost a decade in August 2019. On August 19, smoke from the faraway fires blackened the skies over Sao Paulo. By the next day, the hashtag “#PrayforAmazonia” was sweeping across Twitter. The social media outcry brought world attention to the already dire scientific warnings, and world leaders offered aid and pressured Brazilian President Jair Bolsonaro to take action.

In the Global South, climate change-induced resettlement requires a holistic and integrated approach, involving all stakeholders—state institutions, local customary and civil society institutions—and in particular respectful engagement with local traditional actors and networks. In a policy brief for the Toda Peace Institute, we examined climate change-induced resettlement from the Carteret Islands in the Pacific, a case which encompasses a broad range of issues relevant to future relocation efforts elsewhere. Those who seek to make this type of resettlement possible would do well to heed these lessons.

This summer, United Nations agencies published three reports that offer a sobering assessment of the current state of international security and development, focusing on multidimensional poverty, hunger, and forcible displacement. As some countries succeed in steadily improving the living conditions of their most vulnerable populations, others have struggled to overcome sustained episodes of political instability and violent conflict. Together, the reports affirm the urgency with which the international community must reorient its policy priorities and take action to achieve the Sustainable Development Goals (SDGs) by 2030.

In the Global South, natural resource conflict has largely been considered a consequence of poor governance and weak political institutions. The international community’s solution? Build “green” governance capacity as a way to mitigate violent conflict and improve environmental outcomes. For the international development community, this has meant introducing laws, policies, and practices based on international standards of best practice, and training local regulators to adhere to those standards.
