Ubuhinzi bw’inyamanswa mu nganda n’urwego rwibanda cyane ku mutungo, rukoresha amazi menshi, ibiryo, n’ingufu zo kubyara inyama, amata, n’ibindi bikomoka ku nyamaswa. Ibikorwa binini by’ubworozi bisaba amazi menshi atari ku nyamaswa ubwazo ahubwo no guhinga ibihingwa bibagaburira, bigatuma inganda ziba imwe mu zagize uruhare runini mu kugabanuka kw’amazi meza ku isi. Mu buryo nk'ubwo, umusaruro w'ibihingwa bigaburira bisaba ifumbire, imiti yica udukoko, n'ubutaka, ibyo byose bikaba byiyongera ku bidukikije.
Kudakora neza guhindura karori ishingiye ku bimera muri poroteyine y’inyamaswa byongera imyanda. Kuri buri kilo cy'inyama zakozwe, amazi menshi, ingufu, nintete bikoreshwa cyane ugereranije no gutanga agaciro kintungamubiri ziva mubiribwa bishingiye ku bimera. Ubu busumbane bufite ingaruka zikomeye, kuva mu kugira uruhare mu kwihaza mu biribwa kugeza no kwangiza ibidukikije. Byongeye kandi, gutunganya ingufu nyinshi, gutwara, no gukonjesha byongera ikirenge cya karubone kijyanye nibikomoka ku nyamaswa.
Iki cyiciro gishimangira akamaro gakomeye kubikorwa-byita kumikoro no guhitamo imirire. Mugusobanukirwa uburyo ubuhinzi bwinganda bwangiza amazi, ubutaka, ningufu, abantu nabafata ibyemezo barashobora gufata ibyemezo byuzuye kugirango bagabanye imyanda, bitezimbere, kandi bashyigikire gahunda yibiribwa ikora neza, iringaniza, kandi yangiza ibidukikije. Ubundi buryo burambye, burimo ibiryo bishingiye ku bimera n’ubuhinzi bushya, ni ingamba zingenzi zo kugabanya imyanda y’umutungo mu rwego rwo kurinda ejo hazaza h’isi.
Ibura ry’amazi rigaragara nkikibazo cy’isi yose, gishimangirwa n’imihindagurikire y’ikirere n’imikorere idashoboka. Hagati yiki kibazo ni ubuhinzi bwinyamanswa - umushoferi ukomeye ariko akenshi usanga udahabwa agaciro kumazi meza. Kuva amazi menshi akoreshwa mu bihingwa bigaburira kugeza ku mwanda no kuvanamo amazi menshi, ubuhinzi bw’inganda burimo gushyira ingufu nyinshi ku kugabanuka kw’amazi. Iyi ngingo iragaragaza isano iri hagati y’ubuhinzi bw’inyamaswa n’ubuke bw’amazi, yinjira mu ngero zifatika nk’ikibaya cyo hagati cya Kaliforuniya n’inganda z’inka z’inka muri Berezile, ikanagaragaza ibisubizo bifatika byo kubungabunga umutungo wacu w’ibanze mu guteza imbere gahunda y’ibiribwa birambye.
