Abstract: In agroecosystems,biodiversity performs a variety of ecological services beyond the production of food,including recycling of nutrients,regulation of microclimate,control of soil erosion,remediation of degraded environment,suppression of undesirable organisms and detoxification of noxious chemicals.Conservation of biodiversity in agroecosystem includes management of habitat(artificial and natural),species(targeted or planned biota and non targeted or associated biota)and genetic diversities. A proper management of habitat diversity and an ideal arrangement of planned biodiversity can enhance associated biodiversity and genetic diversity.It is suggested that the researches on functions of habitat diversity in species diversity conservation,influence of agricultural practices on species and genetic diversity and roles genetic diversity may play in fostering disaster resistance,production stability,ecological equilibrium should be emphasized.
