Description The present investigations entitled “Carbon appraisal of different land use
systems of Srinagar District of Kashmir valley” were carried out at two sites in
district Srinagar of Kashmir valley (34o01¢ 08.29² North latitude and 77o47¢
53.56² East longitude) of Jammu and Kashmir during 2009-10 and 2010-11.
Eleven land use systems were selected which are: wasteland/uncultivated land,
Agriculture (Rice-Mustard), Agriculture (Rice –oats), Vegetable (Beans-chilli),
horticulture (apple only), agri-horticulture (apple-vegetables), agri-silviculture
(willow + rice-mustard), plantation forest (willow), plantation forest (Poplar),
natural forest (Blue Pine) and grassland. Site A was at an altitude of 1593-2513 m
amsl and Site B at 1780-2618 m amsl. All the eleven land use systems were
selected at both these altitudinal levels. The plot size in each tree based land use
system was 10 m x 10 m and in cropland/agriculture and grassland it was 1m x 1
m. Existing biomass production, carbon stock and carbon sequestration potential
(CO2 equivalent) of each land use systems were evaluated. The results have
revealed that different land use systems have influence on the production of above
ground biomass, below ground biomass as well as total biomass, carbon stock and
carbon sequestration potential in both the locations. Maximum above ground
biomass (989.743 t ha-1), (931.625 t ha-1) below ground (247.435 t ha-1), (232.906
t ha-1) and total biomass (1237.179 t ha-1), (1164.531 t ha-1) was accumulated in
the Natural forest-Blue Pine land use system at site A and B respectively. The
minimum biomass was recorded in wasteland/uncultivated land use system (1.949 t ha-1) ,(1.893 t ha-1) at site A and B respectively. Total carbon stocks of different
land use systems at site A and B followed the trend : Natural Forest-Blue Pine
(556.731 t ha-1), (524.039 t ha-1) > Plantation forest-Poplar (407.703 t ha-1),
(383.241 t ha-1) > Agri-silviculture-willow + rice (80.162 t ha-1), (76.092 t ha-1) >
Plantation forest-willow (74.498 t ha-1), (70.131 t ha-1) > Agri-horticulture-apple +
vegetable-Beans (64.173 t ha-1), (66.150 t ha-1) > horticulture-apple alone (61.630
t ha-1), (64.279 t ha-1) > agriculture-rice-oats (5.047 t ha-1), (4.809 t ha-1) >
vegetable-beans-chilli (2.556 t ha-1), (2.507 t ha-1) > agriculture-rice-mustard
(2.288 t ha-1), (2.162 t ha-1) > grasslands (1.195 t ha-1), (1.124 t ha-1) >
wasteland/uncultivated land (0.877 t ha-1), (0.852 t ha-1) at site A and site B
respectively. Similar trends were also seen in carbon sequestration potential of
different land use systems. Rate of biomass production at site A (60.4 t ha-1 yr-1)
and at site B (53.227 t ha-1 yr-1) was maximum in the Plantation forest-Poplar land
use system. The rate of carbon sequestration potential was maximum (99.751 t ha-
1 yr-1) and (87.905 t ha-1) at site A and Site B respectively in plantation forest-
Poplar. Land use systems viz. T1- wasteland/uncultivated land (-58.89), (-61.09),
T2- Agriculture-Rice + Mustard (-11.51),(-15.48) T3- Agriculture- Rice + oats
(-23.13), (-23.37), T4- Vegetables(beans-chilli) (-13.02), (-12.26) at site A and B
respectively showed the values in negative that is loss in the land use system.
When the system has tree component in it, it shows gain in the carbon stocks viz.
Horticulture (+65.57), (+68.48), Agri-horticulture (+75.97), (+77.16) Agrisilviculture
(+95.26), (+85.23) Plantation forest-willow (+142.19), (+132.10)
Plantation forest-Poplar (+593.5), (+550.58) and maximum Natural forest-Blue
Pine (+915.46), (+853.11) at site A and B respectively (w.r.t Grassland kept as
100). The findings evinced that at both the locations, Natural forest (Blue Pine)
land use system were having maximum carbon stocks, carbon sequestration
potential, soil carbon pool than all other land use systems and is the best land use
system among all the land use systems under investigation. The follower land use
system was Plantation forest (Poplar) at both the locations, hence need to be
promoted because of having dual advantage of storing carbon and giving
additional benefits like timber, fuel wood and fodder. Natural forest-Blue Pine and
Plantation forest-Poplar based land use system which are the best two land use
systems, they are store houses of carbon in both soil and plants, which need to be
conserved for environmental protection.
