The adet-i deştbani (sometimes known as resm-i destbani) was a charge, or tax, in the Ottoman Empire, which was a penalty for crop damage. The adet-i deştbani may have arisen as a result of tension between nomadic livestock-herders and settled farmers; the former's animals would encroach on, and damage, the latter's arable land; to discourage this, an official called a deştban (who was responsible to a sipahi) was responsible for crop protection - they also guarded against crop theft.
