The Aqueducts of Popovo Polje
Utilizing the unique hydrology of the Trebišnjica river (the world's longest sinking river), the state will build a series of stone aqueducts and mills. This will allow for intensive agriculture even in the dry summer months, making the state self-sufficient in grain and able to withstand long maritime blockades.
