*Agroforestry - Small Landholder's Tool for Climate Change Resiliency and Mitigation*

trees reduce input biomass.

*Carbon stock contributed by trees species in agroforestry of Tehri district.*

*Carbon stock contributed by crops species in agroforestry systems of Tehri district.*

*esculenta, Rhododendron arboretum, Citrus limon, Juglans regia* accumulated maximum biomass carbon stock in the district (**Figure 2**). **Figure 3** represents that among the dominant tree species *Quercus leucotrichophora* contributed maximum (15.11%) biomass carbon stock followed by *Ceitis australis* (6.94%), *Grewia oppositifolia* (6.45%) and rest of species contributes (49.34%). In the present study, *Quercus leucotrichophora* contributed maximum biomass then other tree species. Biomass in *Quercus leucotrichophora* was higher as reported by (Devi *et al.* 2013 [48]; Sharma *et al*. 2010 [49]) for lower Western Himalaya. *Grewia opposoitifoila* contributed maximum number of trees but biomass contribution was lower than *Quercus leucotrichophora,* may be due continous lopping of its branches for fuel and fodder during lean period by local people therefore stunting and bushy growth of *Grewia* was noticed in agroforestry field. Kumar *et al.* (2012) [50] reported that overexploitation of resources from traditional agroforestry

Agrihortisilviculture system had maximum biomass carbon stock at lower altitudes. Across the altitudes, farmers mostly adopted agrihortisilviculture system. Considering biomass and carbon stock, lower altitude (286–1200 m) subtropical zone have more potential for carbon sequestration in agroforestry. *Grewia oppositifoila, Quercus leucotrichophora* and *Celtis australis* were dominant agroforestry tree species which contributed more biomass carbon stock as compared to other species and are mostly adopted by the farmers in agroforestry. Therefore, these three species were considered suitable agroforestry tree species in the district. In agroforestry systems, particularly agrisilviculture and agrihortisilviculture land use systems are playing an important role in the carbon storage an Tehri district of Uttarakhand. Hence these systems need to be promoted further for economic and environmental security. Due to ban of green/live trees felling in the entire Indian Himalayan region, agroforestry systems can be a good source of earning significant carbon credit to thefarmers. Therefore understanding and implementation of carbon sequestration will help to maintain climate change mitigation from agroforestry.
