Climate change will upend the 21^st century world order. It will redefine how we live and work, and change the systems of production, trade, economics, and finance. Even now, in the midst of a global pandemic, it is clear that climate change will be the defining issue of this century. In fact, COVID-19 has only underscored the inadequacy of our responses to global crises and heightened the urgency of this call to action. 21^st century diplomacy will have to raise climate ambition, shape the transformative systems change needed, and promote and facilitate new modes of multilateral collaboration.

“The exploitation of the mining and trade of conflict minerals in the eastern DRC [Democratic Republic of the Congo] has contributed to instability, violence, displacement of people, and severe human rights abuses,” says the Government Accountability Office (GAO) in its annual report, Conflict Minerals: Actions Needed to Assess Progress Addressing Armed Groups’ Exploitation of Minerals. The report examines a sample of filings from 1,083 companies that submitted conflict mineral disclosures required by the Securities and Exchange Commission (SEC) in 2019.

The dry season returned to Brazil’s Amazon region in late July—and with it, forest fires, largely human-made. After making substantial progress in reducing deforestation in the 2000s and early 2010s, Brazil has reversed course and deforestation is rising. In the Amazon, this season has been the worst in more than a decade in number of fires, and second worst in terms of total deforestation, according to satellite data from Brazil’s National Institute of Space Research (INPE), which monitors the situation.

COVID-19 isn’t the only problem going viral. Economic insecurity is driving gold prices to record highs around $1,700 per ounce, causing levels of global mercury pollution to rise too. In the United States coal-fired power plants drive mercury pollution, but globally, the leading cause is small-scale ‘artisanal’ gold mining. Roughly 30 million men, women, and children in poor countries depend on mining for subsistence incomes. Unfortunately, the cheapest and easiest way to mine gold uses mercury, a highly toxic heavy metal the United Nations is striving to eliminate.

Development specialists are sounding the alarm. The pandemic will not be stopped unless we provide safe water to the world’s most vulnerable people, according to UN experts. Soap and clean water are part of the arsenal of weapons we can deploy on the frontlines of the battle to halt the virus’ spread. Yet Covid-19 continues to pose an unprecedented threat to more than 2 billion of the world’s poorest people who lack the access to safe water, sanitation, and health services (WASH) needed to protect them during infectious disease outbreaks, according to the World Health Organization.

As the global climate changes, climate-related security risks are making the existing political, social, and economic challenges even more complicated. The 230 million people who live in the Horn of Africa are highly vulnerable to the impacts of climate change such as droughts and floods. Political fragility and transnational complexities make water governance a matter of regional high-level politics as well as geopolitical tensions. In short, sustainable water governance is critical for achieving resilient peace.
