Interesting restoration project: a 1,000-year-old network of water channels is helping farmers in the Sierra Nevada adapt to the effects of the climate crisis.

José María Martín Civantos, archaeology professor and the driving force behind the project, said: “The system is efficient, the aquifers get replenished and no technology is required...It’s much more manageable and adaptable than building a dam and much more resistant to climate change.”
