Bio-geoengineering

Bio-geoengineering wani nau'i ne na aikin injiniya na yanayi wanda ke neman kara hasken rana (ko albedo) na amfanin gona ta hanyar canza ganye na jiki da / ko halaye na canopy don taimakawa rage yanayin zafi na yanki.

 Gyaran shuka Albedo 
Bio-geoengineering ya dogara da sarrafa halayen amfanin gona, kamar ta hanyar zaɓaɓɓen shuke-shuke ko aikin injiniya na kwayar halitta, don ƙara albedo na amfanin gona. Kodayake akwai bambance-bambance masu ban sha'awa a cikin albedo tsakanin nau'ikan amfanin gona daban-daban, bio-geoengineering yafi mayar da hankali kan gyaran amfanin gona da maye gurbinsa, wanda ke iyakance canjin albedo gabaɗaya, amma canje-canjen sun fi sauƙi a aiwatarwa.Davies-Barnard, Taraka (2014-05-22), Harrison, R M; Hester, R E (eds.), "Cooling the Earth with Crops", Geoengineering of the Climate System, The Royal Society of Chemistry, pp. 105–130, doi:10.1039/9781782621225-00105, ISBN 978-1-84973-953-5, retrieved 2023-11-12
