• Environment can withstand climate change up to
– Long term unmitigated climate change will exceed the
capacity of natural and human systems to adapt.
• The most climate-sensitive economic sectors are
agriculture, livestock and rural poor communities.
• Carbon sequestration in soils is low-cost climate-
– movement of carbon from air to soil can be increased while
the release of carbon from the soil back to the atmosphere is
decreased. This transformation has the potential to reduce
atmospheric CO2, thereby slowing global warming.
• Enhancing carbon sequestration into soil
through environmentally sound scientific
rangeland practices offers a potentially useful
contribution to climate change mitigation.
• The same rangeland will act in diverse way -
potential carbon sink, constant grazing land
for livestock and low cost climate change
• Burning issue - climate change, low cost climate
change mitigation strategy.
• 64 % accessible rangelands out of the 1.7 million
ha are 3.5-37 times overstocked and remaining
are inaccessible, which decrease the potentiality
of rangeland to sequester the Carbon.
• Grassland are an irreplaceable source of
livelihoods and foods security for the poor. The
project focuses on the diverse use of the same
rangeland - from climate change mitigation to
livestock and livelihood improvements.
RATIONALE OF STUDY
• Carbon is major contributing factor for climate
change. Royal society (2001) said that terrestrial
vegetation and soils have been absorbing
approximately 40% of global CO2 emissions.
• Implementing practices to build or rebuild soil
carbon stocks in grasslands could lead to
considerable mitigation, adaptation and
• No one knows what amount of carbon is
sequestrated in soil of Rangeland. The finding of
research will give the amount of carbon in soil of
rangeland and its contribution in carbon

To mitigate climate change by soil carbon
sequestration in scientifically managed
rangelands of Nepal
• To increase soil carbon sequestration through
maintenance of potential grazing lands with
different livestock grazing patterns.
• To mitigate climate change using a low cost
• To address the burning issues of carbon stock
quantification in rangeland of Nepal.
• To find out the amount of carbon in rangeland of
Nepal and its contribution in carbon
• Soil carbon is an important part of terrestrial carbon pool
(Lal and Kimble 1998) and soils of the world are potentially
viable sinks for atmospheric carbon (Lal et al. 1998;
Bajracharya et al. 1998a; Singh and Lal 2001).
• Kirschbaum (2000) estimated that world’s soil contain
about 1500Gt of organic carbon to a depth of 1m and a
further 900Gt from 1-2 m. However, soil is deteriorating at
an alarming rate in developing countries like Nepal due to
land use changes (IPCC 2000), lowering C sequestration.
• Gradual conversion of forest and grassland to cropland has
resulted in historically significant losses of soil carbon
worldwide (Lal 2002).
• Grassland accounts for 12% of the total land area of Nepal
(LMP 1993) which will be a good source for carbon sink.
• Geographic location: Sub-tropical and temperate
rangeland will be selected randomly in each
development regions of Nepal.
• Local survey will be done for stocking density and
• Stratified sampling method with plot size 1m*1m will
be used to estimate the productivity of the rangeland
for Biomass and Dry Matter.
• Stratification of rangeland will be done into broad
classes i.e., high yield, fair yield and low yield grassland
types (Chen et al. 1998).
• At least five soil samples from each plot
using ring sampler (4.8cm diameter, 10cm
long) will be taken and soil testing will be
done in lab.
• The carbon sequestrated by the rangeland
will be estimated by data analysis and
• Intensive training and education regarding
the importance and diverse use of grassland
will be provided.
• Seeding, watering, fertilizing, scientific grazing,
brush management and mechanical treatment
will be done.
• In every month of implementation period
monitoring, evaluation, and data collection will
• New data of the rangeland and carbon content
will be collected at the end of project period.
• Data analysis and publication will be done
• Climate change mitigation.
• A model for a potentially inexpensive option with
environmental co-benefits for carbon
• A well established range land.
• Enhance productivity of livestock.
• Increase the status of most climate-sensitive
economic sectors - agriculture, livestock and rural
• Increase the livelihood.
