As the world inches closer to the critical 1.5°C warming threshold, the demand for decisive climate leadership has never been more pressing. The US withdrawal from the Paris Agreement on January 20, 2025 has left a leadership void. The confluence of these events also has raised the question of whether China can do more to fill the finance gap and help Global South countries decarbonize.

Mekong River Development Faces Public Outcry (Mongabay) 

The Mekong River flows through China, Myanmar, Laos, Thailand, Cambodia, and Vietnam—and a new development on this waterway near the downstream Thailand-Laos border has triggered protests in Thailand. The Pak Beng hydropower development is a joint project of China Datang Overseas Investment and Thailand-based Gulf Energy Development which is estimated to generate 912 megawatts of power to be sold to Thailand’s state energy company. 

Central and South Asia’s water resources are critical for the region’s water, energy, food and environmental security. Major rivers in the region originate from the Hindu-Kush-Himalaya, Pamir, and Tien Shan Mountain Ranges and flow across multiple countries. Unique geographical characteristics make water management a complex and challenging task that is further complicated by a changing climate and increasing demand affecting diminishing water resources. 

The Klamath River Dam removal, slated for early 2024, is a significant milestone in the journey towards bringing back healthy rivers in the United States. This action will restore nearly 300 miles of river habitat in the Klamath and its tributaries across Southern Oregon and Northern California, allowing salmon, a critical source of economic and nutritional value for the local communities, to return. As the world’s largest dam removal and river restoration project in history, this project will have lasting impacts on the health of this river and represents an opportunity for building momentum to continue global river protection and restoration.

Connected and healthy rivers deliver diverse benefits that are often overlooked: freshwater fish stocks that improve food security for hundreds of millions of people, nutrient-rich sediment that supports agriculture and keeps deltas above rising seas, floodplains that help mitigate the impact of floods, and a wealth of biodiversity. Navigating Trade-Offs Between Dams And River Conservation, a new report in the journal, Global Sustainability, reveals that if all proposed hydropower dams are built, over 260,000 km of rivers (160,000 miles), including the Amazon, Congo, Irrawaddy, and Salween mainstem rivers, will lose free-flowing status.

Last April, Vice President Kamala Harris visited the Upper San Leandro treatment plant in Oakland, her Californian hometown. The American Jobs Plan, she told her constituency, will deliver over a hundred billion dollars for the upgrade of U.S. water supply infrastructure. In truth, the investment plan, one of the largest in a generation, is far more ambitious than that. Across all proposed expenditures, it includes not just the upgrade of all water piping, but also remediation, flood protection, ecosystem restoration, and the climate proofing of economic activities. All these initiatives place water at the heart of recovery and resilience.

The travails of the last year, when a bat virus infected humans and turned the world upside down, were an unfortunate reminder of the inseparable ties between society and the natural environment.

So it is with water, which will again this year direct the course of history, through events small and large.

What are the large events to pay attention to? What are the trends and flashpoints?

The Grand Ethiopian Renaissance Dam (GERD) poses numerous challenges for the Nile river basin, but it also presents an opportunity for regional collaboration and shared prosperity, said Aaron Salzberg, Director of the Water Institute at the University of North Carolina and Wilson Center Global Fellow, at a recent event hosted by the University of North Carolina’s Center for Middle East and Islamic Studies.
