Kugira ngo nshobore gutorera umuti ikibazo c’ubushobozi buke mu mafuru y’umuriro ari mu mazi, igihugu canje gikoresha canecane ubushobozi bwo gusubiza inyuma, akenshi bukoreshwa ku ruhande rw’ubushobozi bwinshi-. Ariko rero, ugusubiza inyuma kw’uruhande rw’umuriro mwinshi -kunanirwa gutorera umuti ukudahukana kw’inzira zitatu-. Ikindi kandi, kubera ko ubushobozi bwo gusubiranamo bw’uruzitiro rugufi-bufise ibice birenga 70% vy’ubushobozi bwose bw’uruzitiro, ugusubiza inyuma kw’inguvu nyinshi-ntikugabanya neza ubushobozi bw’uruzitiro rugufi- canke ngo butere imbere umubare w’ubushobozi bw’uruzitiro rugufi{9}}; eka mbere ntishika ku ntumbero yo kwongerera ubushobozi bw’amashanyarazi-ivyiza vyayo ahanini bigarukira ku bijanye n’ubuhinga bwo gutanga amashanyarazi.
Ku bw’ivyo, ibikorwa bimwebimwe vyafashe uburyo bwo gutanga indishi bubiri--bikoresha indishi y’inguvu zikora ku rwego rwo hejuru- no ku rwego rwo hasi-rw’umuriro-ku mafuru mashasha kugira ngo ivyo bibazo bitorerwe umuti. Ingurane ku mpera y'urubuga rugufi-itera imbere cane umubare w'inguvu kandi igabanura ugukoresha inguvu. Gushirwa mu ngiro ku -inguvu zikoreshwa mu gusubiza inyuma kugira ngo haboneke umuti w'inguvu zikoreshwa cane n'ubudasa bw'inzira ku nzira y'umuriro muto -y'umuvuduko muto --mu gihe nyene yongerera ubushobozi bushobora gusubirwamwo -umuti w'ubushobozi n'ubuhinga igiciro-igipimo c'inyungu. Ugereranije n’ugusubiza inyuma umuriro mwinshi, ugusubiza inyuma ubushobozi bukoreshwa ku ruhande rw’umuriro muto bitanga inyungu zidasanzwe mu gutuma ubushobozi butera imbere, kugabanya amajwi y’amajwi, kwongera umusaruro, no kugabanya ugukoresha inguvu. Ariko rero, iyo nzira isaba amahera menshi kandi ituma ibikoresho bikoreshwa mu bidukikije bikomeye, ivyo bikaba bigabanya cane ubuzima bwavyo. Ikindi, ugusubiza inyuma kw’umuriro muto-gufi-gushobora kwongera ingero z’amajwi, bikaba bisaba ingero zo guhagarika amajwi y’urutonde rwa 3- gushika ku rwa 7-; ivyo bituma ishoramari ry’intango ryiyongera, bikongera igihe co kwishura, kandi bikaba bituma habaho amahera menshi yo gusanasana n’ubutunzi muri rusangi butari bwiza. Ku bw’ivyo, muri rusangi ubwo buryo burabereye gusa ku mafuru aherutse kwubakwa.
