Ikimenyetso cy’amapfa

Icyerekezo cy’amapfa, mu karere gikunze gukoreshwa mu gukurikirana ibiza by’amapfa no kwiga urugero nu buremere bw’ibihe by’amapfa.  Ironderero rikoresha imvura nu bushyuhe bwo kwiga itangwa rya mazi ni bisabwa ukoresheje uburyo bworoshye bwo kuringaniza amazi.   Yakozwe n’iteganyagihe witwa Wayine, wasohoye bwa mbere uburyo bwe mu mpapuro zo mu 1965 z’amapfa y’ikirere Wayne Palmer, "Meteorological Drought".
