The effects of management and plant diversity on carbon storage in coffee agroforestry systems in Costa Rica

Autor: Achim Häger

Publikováno v: Agroforestry Systems. 86:159-174

Agroforestry systems can mitigate greenhouse gas (GHG) emissions, conserve biodiversity and generate income. Whereas the provision of ecosystem services by agroforestry is well documented, the functional relationships between species composition, div
