Experts Sound Alarm Over Peru-Brazil Biooceanic Railway Risks (Mongabay) 

A proposed railway linking Peru’s Pacific coast to Brazil’s Atlantic is drawing alarm from conservation experts and Indigenous rights advocates. Brazil and China signed a feasibility study agreement for new route crossing both the Andes and the Amazon rainforest in July 2025, with China playing a central role in financing and development. Two alternatives are under consideration, with one running through Peru’s Ucayali region and the other through Madre de Dios, but neither has been approved. A single line could impact 15 protected natural areas, threatening over 1,800 campesino communities, as well as territories inhabited by Indigenous peoples in voluntary isolation. 

In the summer of 2025, Tehran almost reached “Day Zero” – a designation for the moment when the city’s municipal water supply was no longer able to meet basic demand through normal distribution systems. Indeed, Iranian President Masoud Pezeshkian has repeatedly warned that the capital may need to be relocated due to the worsening water crisis.

Energy Fallout from Iran War Signals a Global Wake-Up Call for Renewable Energy (Associated Press) 

Fighting in Iran has effectively halted oil exports through the Strait of Hormuz — a chokepoint carrying roughly a fifth of the world’s oil and LNG — triggering an energy shock that is exposing the deep vulnerabilities of fossil fuel-dependent economies. Asia has been hit hardest, while Europe and Africa face mounting pressure from rising fuel costs and inflation. The crisis has sharpened debate over the uneven global energy transition. China’s substantial renewable buildout has provided meaningful insulation from the shock, while countries like Japan and India — which prioritized fossil fuel diversification after past crises — find themselves more exposed. Vietnam’s solar capacity is saving hundreds of millions in projected import costs. Meanwhile, Bangladesh has shuttered universities to conserve electricity, and India faces a cooking gas shortage. With more than 90% of new renewable projects now cost-competitive with fossil fuels, experts argue the strategic case for domestic clean energy has never been clearer.  

Native nations in the United States have played leading roles in some of the country’s most spectacular conservation success stories. For instance, calls by the Yurok, Karuk and Hoopa Valley tribes resulted in the world’s largest dam-removal and salmon restoration project on the Klamath river in California and Oregon.

“Do not give away Diego Garcia,” warned U.S. President Donald Trump on February 19, as the United Kingdom moved forward with plans to transfer sovereignty of the Chagos Archipelago to Mauritius. While the Chagos Archipelago has often been viewed through the prism of the sovereignty dispute between the United Kingdom and Mauritius, the islands today serve as a fulcrum for regional rivalries and great-power competition.

Pakistan’s Grassroots Solar Mitigates Middle East Energy Crisis Impact (The Guardian)

Russia’s invasion of Ukraine in 2022 also sparked a grassroots solar boom in Pakistan. Surging LNG prices and unreliable grid electricity resulting from the war’s broader effects pushed citizens to invest in rooftop solar as a one-time cost alternative to perpetually high electricity bills. Between December 2021 and December 2025, solar energy’s share of grid-supplied electricity in Pakistan jumped fivefold. Today, solar provides one-fifth of the country’s electricity.

Last fall, I travelled back to my hometown in rural Wen’an County, Hebei Province, and was surprised to find my aunt Lu had installed 12 solar panels on the roof of her house. Because I am a low-carbon policy wonk at a Beijing consultancy, I peppered her with energy questions as we admired the rooftop panels. “So, where does the electricity go? To your own appliances, an aggregator, or the grid company? Are you paid for renting out the roof or for selling the electricity?”
