The Mining Town Funding Congo’s Rebels and Tech Giants (Reuters)

In April 2024, the M23 rebel group seized control of Rubaya, a mining town that produces 15% of the world’s coltan—a critical mineral worth used in mobile phones, computers, and aerospace components. Rebels imposed a parallel administration in the town, and placed a 15% tax on mineral traders that generates $800,000 monthly from levies. Thousands of impoverished miners in the town, however, still work 12-hour shifts in dangerous conditions earning just $5.15 per day.

As global powers race to secure critical minerals, Myanmar’s rare earths have emerged as both prize and flashpoint. Last week, Reuters reported that the Trump administration has been privately reviewing competing proposals to access Myanmar’s heavy rare earth minerals, including potential engagement with Myanmar’s military junta and direct negotiation with the Kachin Independence Army (KIA), an ethnic armed group that now controls key extraction sites. Since the February 2021 military coup, rare earth mining has surged in northern Kachin State near the Chinese border, where the KIA has seized highly valuable rare earth mines and a critical corridor in the global supply chain. What began as a local insurgency has evolved into resource-backed diplomacy, drawing in China, India, and now the United States.

Community Patrols Offer a Blueprint to Enforcement of Conservation Law (Mongabay)

In the remote reaches of the Brazilian Amazon, an experiment in grassroots enforcement is yielding results. The Voluntary Environmental Agents Program, which trains and funds residents to patrol their own territories, has reduced illegal fishing, hunting, and logging by 80%. Operating in the Mamirauá and Amanã reserves, the program equips communities with surveillance tools, environmental education, and leadership training, weaving traditional knowledge into conservation efforts.

The World’s Children Face the Most Severe Impacts from Wildfire Smoke (Mongabay)

Evidence of the alarming impacts of wildfire smoke on child health is growing. Children’s developing lungs, faster breathing rates, and greater outdoor exposure make them uniquely vulnerable, and the threat is intensifying as wildfires grow more extreme, incinerating not just forests but urban areas, releasing toxic heavy metals and chemicals. 

As 2025 marches into its third month, the governance challenges that accompany rising demand for natural resources are not only on the front burner—they are proliferating—and  becoming entangled with the drivers of conflict and cooperation.

The heated competition for resources has bubbled up in a proposed billion-dollar deal for Ukrainian minerals now making global headlines. The view that critical minerals like lithium, manganese, and others could become bargaining chips in potential peace talks demonstrates how central they’ve become to global competition—and to the economic and political future of countries around the world.

Much of the current narrative surrounding critical minerals puts speed and competition in the foreground. Yet the how of mining matters immensely to create and maintain stable mineral supply chains. Reliable and diversified supply chains create win-win scenarios for all stakeholders by incorporating best-in-class environmental standards and true community partnerships.

In December 2024, China banned exports of gallium, germanium, and antimony to the United States. Prices for these critical minerals soon reached all-time highs. The ban emphasized China’s dominance over the sector, including practically the entire graphite supply chain, 87% of rare earths refining, 70% of cobalt refining, and 60% of battery-grade lithium refining.

EU Parliament Suspends Rwandan Critical Mineral Pact Over Links to DRC Conflict (Mongabay)

Rwanda and the DRC both have large reserves of critical minerals essential to the clean energy transition. Yet the EU has voted to suspend a cooperation agreement on mineral extraction in the region after the Rwandan-backed rebel group M23 seized key areas in the DRC’s eastern provinces.
