Hundreds of millions of people around the world
rely on grasslands to feed the livestock which are the foundation of their
livelihoods. Yet poor land management has left large swathes of the world's
grasslands degraded - an environmental problem which also has direct
implications for livestock-dependent communities.
To help address these concerns, FAO and the
Chinese Academy of Agriculture Science (CAAS), the World Agroforestry Center
(ICRAF) and China's Northwest Institute of Plateau Biology (NWIPB) have for the
past several years been working to link grasslands restoration efforts to
international climate financing schemes.
Restoring degraded grasslands through more
sustainable grazing practices and forage production can substantially improve
animal feeds and productivity, benefiting herders and others who depend on
livestock-rearing for income and food.
At the same time, restoring degraded grasslands
can also trap large volumes of atmospheric carbon, mitigating climate change.
For this to happen, economic incentives are
critical.
Carbon crediting schemes that pay projects for
reducing greenhouse gas emissions and sequestering carbon do exist, in theory
offering farmers the potential to earn money in exchange for adopting practices
that help mitigate climate change.
But participation of agriculture in carbon
markets - including those involving grazing-based livelihood systems - has so
far been quite small.
One reason for this is the challenge of
measuring how much carbon is being trapped as a result of improved farming
practices. Only with reliable and affordable approaches measuring, reporting
and verifying carbon sequestration can provide access to climate funds.
This challenge is now being addressed by a new
methodology developed by FAO, CAAS, ICRAF and the NWIPB.
A new tool, now tested and endorsed
The methodology allows for either
direct measurement of carbon sequestration on sustainably managed grasslands
through soil sampling or computer modeling of sequestration based on soil types
and farming activities. The use of modeling can substantially reduce costs of
measurement.
Tested over the past several years using field
data from a project site in Northern China and computer modeling, the
methodology has now won approval by the non-profit Verified Carbon Standard
(VCS), a voluntary greenhouse gas accounting programme used by projects around
the world to verify and issue carbon credits in voluntary emissions markets.
According to findings from the case study in
Northern China, herders could sequester an average of 3 tCO2 per hectare of
grassland each year over the next 20 years, through the application of improved
practices, such as reduction and rotation of grazing pressure on overstocked
sites and the sowing of improved pastures and fodder crops close to households.
The new methodology is tailor-made for the assessment and quantification of
those climate benefits.
"Now that the tool has won the
certification needed for recognition by international carbon markets, project
developers and farmers have a new opportunity to implement grasslands
restoration projects at a meaningful scale, improving the productive potential
of their grasslands and helping to reverse historic carbon losses," said
Henning Steinfeld of FAO.
Returns from the carbon finance and other
mitigation funds can be invested in further restoring the long-term health of
the lands upon which herders and grazers depend and in building up marketing
associations to improve their incomes, raising families incomes and improving
household food security," Henning Steinfeld added.
The methodology also offers countries a tool
that can be adapted and used to support monitoring and verification when
developing Nationally Appropriate Mitigation Actions (NAMAs) to reduce GHG
emissions.
Significant potential
The methodology can be applied
worldwide wherever countries work to sustainably feed a growing population
while lowering their carbon footprint, especially in grassland-rich countries..
"In China -- with 400 million hectares of
grasslands, and highly supportive national policies and measures that have been
initiated in China to incentivize the uptake of sustainable grassland
management practices such as the Grassland Law of the People's Republic of
China; the Grassland Ecology Conservation Subsidy and Reward Mechanism; and the
Grassland Retirement Program, there is enormous potential for this new
methodology," noted Li Yue of CAAS.
CAAS and FAO are continuing to work together to
identify opportunities to pilot this methodology and upscale its use in China
and beyond.
