i'm siavash ardalan, and i report on the environment for bbc persian.ing people suffering, i wanted to understand what caused these water shortages. is it climate change or are there other factors? what is happening in iran today is the outcome of decades of bad management, poor environmental governance and a lack of foresight, not climate change. the bbc cannot operate freely inside iran, so i've pieced the story together using social media, and visited the united states to see how they manage their water. wow, this is amazing! look how much the water has gone down. as iran and the rest of the world tackle water scarcity, i'll be asking — what can be done to improve the water supply for people in khuzestan? khuzestan has long been thought of as lush and green, with wetlands and diverse wildlife. its rivers used for leisure and agriculture. but over the last decades, that has changed. today, rivers are dirty or run dry. the great horolazim wetland has been drained for oil extraction. the environment and communities destroyed. iran's students�* news agen
