Natural balance and hydrologic cycle at Sultan Marshes were destroyed due to the construction of dams, wells and drainage channels due to basin-wide irrigated farming support policies that started in Develi Basin in 1973. From the beginning of 2000s, the water quantity of the Sultan Marshes decreased dangerously because of the water-guzzling-products farming, agricultural irrigation, illegal well drilling, losses due to the existing irrigation techniques and less water flow to the marshlands due to the dams; as from 2003 marshlands have almost dried out. The effects on local people were unequal: while landowners adopted agricultural irrigation, loan use, base price, market support systems that were prioritized for the last 25 years, landless farmers who make their own living through reed and sedge cutting and animal husbandry on open pastures have lost their sources of income. Decrease in the amount and quality of reeds and poor quality animal production due to the dried pastures put these groups living at risk. On the other hand the loss of biodiversity and the drop in the bird species richness (for which the region was known) reached a serious level.
