Earthworms commonly occur within the soil. They alter physico-chemical and biological regimes of the soil through their activities, such as burrowing, casting, feeding and propagating, and therefore are known as 'ecosystem engineers'. Through their activities, they provide a number of ecosystem services which are ecologically and socio-economically important. This article reviews the role of earthworms in improving soil structural and functional properties, which serves as key determinants of soil ecosystem services and economic benefits for the farmers. A methodology of economic evaluation of the agro-ecosystem services provided by earthworms has been demonstrated. Further, the information gaps and future research have been discussed for ensuring sustainable agroecosystems management.

Abstract


Earthworms commonly occur within the soil. They alter physico-chemical and biological regimes of the soil through their activities, such as burrowing, casting, feeding and propagating, and therefore are known as 'ecosystem engineers'. Through their activities, they provide a number of ecosystem services which are ecologically and socio-economically important. This article reviews the role of earthworms in improving soil structural and functional properties, which serves as key determinants of soil ecosystem services and economic benefits for the farmers. A methodology of economic evaluation of the agro-ecosystem services provided by earthworms has been demonstrated. Further, the information gaps and future research have been discussed for ensuring sustainable agroecosystems management.
