Ukuba sifuna ukuyeka okanye ubuncinci singalonyusi utshintsho lwemozulu, enye yezinto ekufuneka siyenzile yile yeka ukugawula imithi. Ezi zityalo zifunxa isixa esikhulu sekharbhon diokside (CO2), yenye yezona gesi zibamba kakhulu. Kodwa eso inokuba sisisombululo esingenakufezekiswa, ngakumbi xa kuthathelwa ingqalelo ukuba abantu, nokuba bahlala phi, bahlala befuna ukuvela kwaye babe neemeko zokuphila ezingcono.
Ukanti, uvavanyo olwenziweyo e-Afrika kwaye lwapapashwa kwiphephancwadi iSayensi, lutyhile oko ukunika abancinci abancinci imali kunceda ukulwa nokutshintsha kwemozulu.
Kumazwe amaninzi asakhasayo, afana neUganda (Afrika), ukunciphisa indlala kunye neenzame zokugcina okusingqongileyo kuyahambelana, kodwa ngamanye amaxesha ukuthatha amanyathelo ayimfuneko akukho lula. Ama-70% amahlathi aseUganda asemhlabeni wabucala, uninzi lwawo lolwabanini abahlwempuzekileyo, ukuze baphile, bathande ukugawula imithi ukuze babandakanyeke kwezolimo.
Ngesi sizathu, uSeema Jayachandran, isazi ngezoqoqosho kwiYunivesithi yaseNyakatho-ntshona, kunye noJoost de Laat, ingcali evela kwi-Dutch NGO Porticus, badibana ne-US NGO Amanyathelo ngamanyathelo endlala ukwenza ulingo oluqulathe nikela nge-US $ 28 (malunga nee-euro ezingama-24) ngonyaka ngehektare nganye yehlathi kubantu base-Uganda abangama-60 kwimeko enye: ukuba bangaligeli ihlathi kangangeminyaka emibini. Ingakhangeleka ngathi yimali encinci kakhulu, kodwa kuya kufuneka ukhumbule ukuba umhlaba okhoyo uphantsi kakhulu.
Iziphumo zazikhuthaza. Emva kweminyaka emibini, kwiilali ezingakhange zibekho kule nkqubo, i-9% yemithi yayigawuliwe, kodwa kuleyo yayifumene inkuthazo, bekukho phakathi kwe-4 kunye ne-5% ngaphantsi. Ngamanye amagama, baqhubekile nokugawula amahlathi, kodwa kuncinci kakhulu.
Oku kulingana Iitoni ezingama-3.000 ze-CO2 zingaphantsi ezikhutshelwe emoyeni, ngokuqinisekileyo inomdla kakhulu. Ngokuka-Annie Duflo, umlawuli we-NGO Innovations for Poverty Action, eli linge liza kusebenza ukulwa notshintsho lwemozulu, ngelixa likhusela iindawo zokuhlala ezisongelayo kwaye linceda amafama amancinci.
