Agriculture (s / x) ndiye gawo lofunikira kwambiri pachuma m'maiko onse padziko lapansi, chifukwa imapatsa anthu chakudya, zopangira zopangira zovala ndi nsalu zofunikira tsiku ndi tsiku. Anthu adayamba kulima, kulima mbewu zosiyanasiyana ndikuweta ziweto kale, chifukwa chake ntchito zaulimi ndi ziweto ndi ntchito zachikhalidwe cha anthu.
Kuphatikiza pa maubwino, zaulimi zimakhudzanso chilengedwe, mwinanso zoyipa. Pazinthu zamtunduwu, phindu lalikulu ndizopangira nthaka, zomwe ndi nthaka yachonde, yomwe imatha kutulutsa zokolola zambiri. Nthaka yachonde imapatsa mbewu ndi madzi ndi mpweya, zinthu zofunikira komanso kutentha, zomwe zimapangitsa kuti pakhale zokolola zambiri. Mwambiri, ulimi umapereka zopangira m'magawo awa azachuma:
- mafakitale azakudya;
- mankhwala;
- makampani opanga mankhwala;
- makampani owala.
Mavuto akulu amakhudza momwe ulimi umakhudzira chilengedwe
Zachilengedwe zamakampani opanga mafakitale ndizoti zochita za anthu zimakhudza chilengedwe, monganso momwe bizinesiyo imakhudzira zochitika zachilengedwe komanso moyo wa anthu iwowo. Popeza zokolola za ulimi zimadalira chonde, zimalimidwa mwa njira iliyonse, pogwiritsa ntchito matekinoloje aulimi amitundu yonse. Nthawi zambiri izi zimabweretsa kuwonongeka kwa nthaka:
- kukokoloka kwa nthaka;
- chipululu;
- mchere;
- toxification;
- kutaya malo chifukwa chachitukuko.
Kuphatikiza pa kugwiritsa ntchito mopanda nzeru zanthaka, ulimi umawononga chilengedwe ndi mankhwala ophera tizilombo, herbicides ndi ma agrochemicals ena: malo osungira ndi madzi apansi, nthaka, mpweya. Kuwonongeka kwakukulu kumachitika m'nkhalango, chifukwa mitengo imadulidwa kuti imere mbewu m'malo mwake. Zonsezi zimabweretsa vuto lachilengedwe la nkhalango. Popeza machitidwe okongoletsa osiyanasiyana ndi ngalande zapamtunda zimagwiritsidwa ntchito pamakampani agro, kayendetsedwe ka matupi amadzi oyandikira akuphwanyidwa. Malo okhala zamoyo zambiri akuwonongedwanso, ndipo chilengedwe chonsecho chikusintha.
Chifukwa chake, ulimi umabweretsa kusintha kwakukulu pachilengedwe. Izi zikugwira ntchito pazinthu zonse zachilengedwe, kuyambira mitundu yazomera mpaka mayendedwe amadzi m'chilengedwe, motero ndikofunikira kugwiritsa ntchito moyenera zinthu zonse ndikuchita zoteteza chilengedwe.
