With fertile soil and steady sun”and just enough irrigation water”the trees have already grown ten feet tall (three meters), enough to shade his dogs.
This 250-acre plot in the Mexicali Valley, south of Yuma on the Arizona border, is part of an innovative effort to restore small parts of the two-million-acre (8,100-square-kilometer) Colorado River Delta. Thanks to dams and canals that have diverted water to farm fields and cities, the Colorado no longer reaches the sea, and its delta has been desiccated. (See “8 Mighty Rivers Run Dry From Overuse.”)
But now a coalition of environmentalists, community leaders, and governments, working under a U.S.-Mexico agreement that is allowing them to reclaim a small fraction of the river’s water for the environment, are trying to reverse some of the damage in a few places, including Miguel Alem¡n. Pati±o is the president of the local restoration committee ….
