Ilimin halittu.

Agroecology wani horo ne na ilimi wanda ke nazarin hanyoyin muhalli da aka yi amfani da su ga tsarin samar da aikin gona. Samar da ka'idojin muhalli na iya ba da shawarar sabbin hanyoyin gudanarwa a cikin tsarin agroecosystems. Kalmar na iya nufin kimiyya, motsi, ko aikin gona. Masana ilimin halittu suna nazarin tsarin halittu iri-iri. Yankin ilimin kimiyyar noma ba shi da alaƙa da wata hanya ta noma, ko yana da kwayoyin halitta, mai sabuntawa, hadin kai, ko masana'antu, mai zurfi ko mai yawa, kodayake wasu suna amfani da sunan musamman don madadin aikin gona.

OECD ta bayyana ilimin kimiyyar muhalli a matsayin "bincike game da alaƙar amfanin gona da muhalli".  Dalgaard et al. suna nufin ilimin muhalli kamar nazarin hulɗar tsakanin shuke-shuke, dabbobi, mutane da muhallar a cikin tsarin aikin gona.

Agroecology tsari ne na gaba ɗaya wanda ke neman sulhunta noma da al'ummomin yankin tare da matakai na halitta don amfanin yanayi da hanyoyin rayuwa.

Agroecology bisa ga asali iri-iri ne, gami da kimiyya kamar aikin gona, ilimin halittu, kimiyyar muhalli, ilimin zamantakewa, tattalin arziki, tarihi da sauransu.  Agroecology yana amfani da ilimin kimiyya daban-daban don fahimtar abubuwan da ke tattare da halittu irin su kadarorin ƙasa da hulɗar tsire-tsire, da kuma yin amfani da ilimin zamantakewa don fahimtar tasirin ayyukan noma a yankunan karkara, matsalolin tattalin arziki don bunkasa sababbin hanyoyin samar da kayayyaki, ko abubuwan al'adu da ke ƙayyade ayyukan noma. Abubuwan  na tsarin tsarin agroecosystems da aka yi nazari na iya haɗawa da: yawan aiki, kwanciyar hankali, dorewa da daidaito .  Agroecology ba'a iyakance ga kowane ma'auni ɗaya ba; yana iya kasancewa daga kwayar halitta ɗaya zuwa ga jama'a gabaɗaya, ko kuma daga filin guda ɗaya a gonar da aka bayar zuwa tsarin duniya. 

Paul Wojtkowski differentiates the ecology of natural ecosystems from agroecology inasmuch as in natural ecosystems there is no role for economics, whereas in agroecology, focusing as it does on organisms within planned and managed environments, it is human activities, and hence economics, that are the primary governing forces that ultimately control the field. Wojtkowski discusses the application of agroecology in agriculture, forestry and agroforestry in his 2002 book.
