Iri somo rigaragaza akamaro ko kurwanya ibyatsi bibi mu buhinzi bw’ikawa. Icyatsi kibi ni ikimera cyose kimera aho kidakenewe. Mu mirima y’ikawa, ibyatsi bibi bihangana n’ibiti by’ikawa ku ifumbire iri mu butaka, amazi, urumuri rw’izuba n’umwanya. Iyo bitagenzuwe, bituma ibiti by’ikawa bigira intege nke kandi bigabanya cyane umusaruro. Ni ngombwa gukorera ku gihe ibikorwa byo guca ibyatsi, kugira ngo bigabanye iryo hangana kandi hirindwe ko ibyatsi bikwirakwira. Ibyatsi bigomba gucibwa mbere y’uko bitanga imbuto na mbere yo gutera ifumbire kugira ngo intungagihingwa idatakazwa, kugira ngo ibyatsi bitazapfundikirwa munsi yayo, kandi igihe ubutaka bufite ubuhehere kugira ngo imizi y’ibyatsi ibashe gukurwamo byoroshye. Gukorera ku gihe bigabanya imirimo kandi bigatuma ifumbire ikoreshwa neza. Ibice bitandukanye by’igiti cy’ikawa bisaba uburyo bwihariye bwo guca ibyatsi. Munsi y’aho amashami arangirira, ibyatsi bigomba gukurwamo n’intoki, kugira ngo harindwe imizi mito iri hafi y’ubutaka ifasha igiti gufata intungamubiri. Guhingisha isuka cyangwa gucukura muri icyo gice ntibikwiye, kuko byangiza imizi kandi bigabanya umusaruro. Iyo umuhinzi afashe ingamba hakiri kare, agahitamo igihe gikwiye n’uburyo bukwiye, ashobora kubungabunga umurima usukuye, kurinda imizi y’ikawa, no gufasha ibiti by’ikawa gukura neza no gutanga umusaruro mwiza.
