From Los Angeles to Cairo, the global water crisis is escalating – but Valencia’s Tribunal de les Aigües could inspire a solution

Every Thursday at noon, outside the west door of Valencia’s cathedral, nine black-cloaked figures – one wearing a banded cap and with a ceremonial harpoon by their side – gather for their weekly meeting, as they have done for hundreds of years. This is the Tribunal de les Aigües (Tribunal of Waters) – a water court that may be the oldest institution of justice in Europe.

It may seem like a relic of the past, but in fact, in the midst of a global water crisis, the tribunal is more relevant than ever. We are a civilisation at risk of committing aquacide. Due to droughts caused by climate change, expanding industrial agriculture and growing urbanisation, one in every four people will be affected by water scarcity over coming decades, with cities from Los Angeles and Cairo to Melbourne and São Paulo facing acute shortages. Water conflicts are on the rise, both within and between nations – we are increasingly fighting over water rather than oil and land. Moreover, in countries such as the UK, private water companies are jacking up prices and siphoning off super-profits while dumping sewage in the rivers.

Connection found between early exposure and bronchitic symptoms in adults without previous lung problems

Air pollution breathed in during childhood is one of the factors in adult lung health, according to a new study.

The origins of the study date back to 1992 when researchers began investigating the effects of air pollution on groups of children in California. Some of these children are now in their 40s.

The Washington State Office of Financial Management (OFM) has published its assessment of scrapping the state’s cap-and-trade programme should ballot initiative 2117 (I-2117) succeed, but failed to discuss several negative impacts it might have on the economy, according to a think-tank.

US Environmental Protection Agency (EPA) standards finalised this spring that envision a prominent role for carbon capture and storage (CCS) in reducing power plant emissions have piqued interest in the emerging technology, but hesitancy remains around legal challenges, a conference heard Thursday.

The regulatory framework for Mexico’s long-delayed emissions trading system (ETS) is in the final stages of review, and the private sector is increasingly interested in offsetting strategies, according to a Mexican industry representative speaking on a webinar Thursday.

Tax credits and other incentives towards carbon capture and storage (CCS) in the US are likely to continue under a potential second Trump administration, experts told conference attendees, also providing recommendations for project developers in a post-election landscape.
