4 iindlela zokusombulula ingxaki yindlala ehlabathini

Ngelishwa, asingabo bonke abemi umhlaba bethu ukufikelela izidlo ezithathu ngosuku. Abaninzi abakwazi ukufikelela iimveliso ezingundoqo, indlala rhoqo, nokuba yayisecicini yobomi nendlela yokufa. njani na ukulungisa le ngxaki ehlabathini lonke?

izibalo kuthiya

Ngokutsho Ezimanyeneyo, indlala ihlabathi libe enye yezona ngxaki nokoyika abantu mihla. Ngokutsho uphando kubantu abangaphezu kwama-7 billion ehlabathini phantse zizigidi 870 ubunzima kukungondleki ezingapheliyo, yaye omnye kwabasibhozo. Abantu abaninzi balambile bahlala kumazwe anoqoqosho phambili kakuhle.

ikakhulu izinto ezimbi kwilizwekazi le-Afrika. Ngokutsho koqikelelo UN, kwezona esembindini emazantsi kwilizwekazi abondlekanga okanye yindlala abantu abangaphezu kwezigidi 250 - malunga ikota yabantu balapha.

Isimanga, kodwa le ngxaki ukwasebenza kumazwe nempumelelo kakhulu. Kwiminyaka elishumi edlulileyo inani abangondlekanga linyuke abantu malunga 4 million.

Nangona inkqubela ekulweni indlala ehlabathini, le ngxaki yehlabathi ngamnye karhulumente. isisombululo sayo kubalulekile nje kuphela abantu abasweleyo, kuba njalo izizathu amafama kubani inika ithuba lokukwazi ukufumana imali eninzi.

Kwenzeka njani ukuba boyise indlala ehlabathini? Kukho ezine sisombululo ezifanelekileyo kule ngxaki.

Ukuqaliswa kwe biotechnology

Kwiminyaka engamashumi ehlabathini lonke kukho Kwiingxoxo ezishushu malunga nokusetyenziswa ukuguqulwa yemfuza kwezolimo. Nangona izikhalazo abavela kwimibutho eyahlukeneyo zonqulo kunye nezentlalo, ukuba ube lusindiso lokwenene indlala. Umzekelo, ukutshintsha isakhiwo genetic sesivuno zokutya - irayisi, umngqusho, iitapile, icassava - likuvumela ukuba wenze kubo ukumelana nezifo, ukwandisa imveliso yabo nokuphucula ixabiso yesondlo.

Ukongezelela, ngokusebenzisa i "izityalo ugonyo" ilahleko kwisivuno zinakho ukuthintelwa zizinambuzane okanye izifo. Umzekelo, University, esebenzisa biotechnology, yakwazi ukuba ukukhula kabini ngokukhawuleza kangangoko icassava, eyabonakala kakhulu okunesondlo ngakumbi xa kuthelekiswa yokuqala.

Kakade ke, kukho imingcipheko ethile enxulumene nokusetyenziswa ukuguqulwa yemfuza yezityalo. Noko ke, kule imeko, injongo Mathews indlela. Ukuba unalo ithuba usebenzisa biotechnology kokondla bonke abemi umhlaba, kufuneka ukuba uthathe ithuba.

Ukukhetha phakathi zokulima kunye nezolimo mveliso

Namhlanje, kukho iindidi ezimbini iinkqubo ukutya - ezolimo mveliso kunye ezincinci (nabalimi). Ngokutsho umbutho yophando njalo njalo Group, uhlobo lokuqala inzuzo ukuba ngaphezu kwe-70% yomhlaba wezolimo kunye nezibonelelo. Kodwa yonke into avelise ngaphantsi kwe kwisithathu yokutya yehlabathi lonke. Ngelo kwiifama Kwangaxeshanye, esebenzisa% 30 kuphela kwezibonelelo, ukuphuhlisa bonke ukutya.

Le indida Kulula kakhulu ukuba uchaze. Enyanisweni, kwiindawo ezinkulu bokuhlwayela izivuno zezityalo omnye uya kuba mkhulu kakhulu xa kuthelekiswa nezizathu ezincinane. Noko ke, amafama akhasayo kuxhamla ngenxa guqulo izityalo, imfuyo kunye neeklasi igadi ngaxeshanye. Bayakwazi ukuvelisa ukutya okuninzi ngeli lixa kuncitshiswa ukusetyenziswa kwezibonelelo kunye ukonga iindleko zothutho. Oku kunceda nje ukuba ulwe ngempumelelo ngakumbi indlala ehlabathini, kodwa ukunqanda utshintsho lwemozulu kummandla, kwaye ixhasa a eziphilayo enkulu. Ke okona kubalulekileyo, ukuze iindlela ezinjalo olusebenzayo lingasetyenziswa kumashishini amakhulu-scale zezolimo ngempumelelo.

Uqeqesho amafama ngempumelelo zokulima

Ngelishwa, abalimi abaninzi nje, bangawazi iindlela ezintsha olusebenzayo izilimo. Ukuba uchitha ixesha kunye nabo kwatisa, umzekelo, iindlela ezintsha lokutyala irayisi, intshayelelo izichumisi ezahlukeneyo okanye ukusetyenziswa iindidi ezintsha imbewu, nemveliso zabo ngcono kakhulu.

Indlela elula kakhulu ukunceda amafama usebenzisa umbutho Indian Digital Green. Oku kubeka lonke ulwazi ngokohlobo vidiyo. uncedo olunjalo kwenza amafama ukwandisa imveliso iimveliso zokutya, nokunyusa nje ubutyebi bakhe, kodwa ukuphucula uqoqosho lwengingqi.

kwezolimo Urban

Inqanaba ezidolophini yehlabathi ikhula. wayesele Wafika umgangatho-25%. Kulo mzekelo, uninzi ukutya sisuka lwemihlaba ibekwe ngaphandle kwesixeko, ngokuzenza zibe ezibizayo.

Eneneni, ukutya zikhuliswa kwizixeko. Ukulungiselela le njongo, efanelekileyo uphahla, izitiya kunye neepaki. Ikhala a bit ndinamaphupha, kodwa enyanisweni yokwenene kakhulu.
