The villagers of #Surajpura have built a wall: a 15ft (4.5 metre) #MudBulwark that snakes through barren land for nearly a mile, with an equally long trench dug beneath it. The wall passed its strength test last year when it stopped rainwater runoffs, and the trench channelled the water to parched farms in the #drought-prone region of #Rajasthan in north-west #India. #ClimateChange#WaterCrisis
