I will be glad to cooperate. I have many resources in Persian. An introduction is needed to understand them in context. In central deserts of #Iran vegetation is not rich enough to nurture big cattles and there's not enough water to cultivate vast fields, #Persians use #Qanat as a sustainable irrigation system to overcome drylands and cultivate small scale gardens. #Gardening needs rich soil and a sustainable source of Nitrogen and Phosphorus is needed. As I mentioned drylands is not suitable for herding big animals so they decided to attract desert pigeons and tame them to nest in #Dovecotes. Persians use their manure as a fertilizer and a great source of phosphate to produce gunpowder. Pigeons control the pests and attract snakes and birds of prey. Finally snakes and birds of prey hunt the mice. It's a wise intervention in web of life without any destructive impact.
