In addition, land management has other impacts
on the carbon balance. On the one hand, there are
additional emissions, especially CO₂, from the use of
machinery and equipment on farms. On the other
hand, certain land management practices can release
significant amounts of carbon from soils, forests and
swamps. Compared to other sectors, agriculture is
expected to be able to achieve significant emission
reductions already before 2030. However, further
reductions will be more limited beyond that point.
Along with transport, agriculture is expected to
become one of the main sectors where full
decarbonization will not be achieved even in the long
term. Overall emissions from agriculture have already
declined since 1990, with CO emissions
proportionately larger than non-CO emissions.
However, the rate of decline has slowed over the past
decade, indicating that more action is needed to
support the transition to a low-carbon economy in this
sector and in rural areas in general.
The land use industries are among the few that can
have a positive impact
carbon balance. This is due to the amount of
carbon storage and sequestration that can occur
through land, which can more than offset emissions
associated with land use. Harnessing the potential for
carbon sequestration and reducing greenhouse gas
emissions through better management of soils and
biomass is critical. Doing this consistently is
especially important. Increasingly, Member States
can look to their Land Use, Land-use Change and
Forestry Sectors to contribute to climate change
mitigation efforts. They can also be supported, for
example, by afforestation and forest management and
agroecological and climate measures. This, along
with greater resource and energy efficiency, will in
turn help support rural businesses and be a strong
selling point for green products and low-carbon
tourism (Molchanova, 2019).
Effective management of carbon emissions in
ecosystems is not only about the environment. The
Low Carbon Green Economy takes this idea further
to ensure that an efficient and reliable supply of low
carbon energy brings environmental, economic and
social benefits. This should make ecosystems
healthier and more resilient or adaptable to change,
which means increased productivity and a more
sustainable long-term future for productive sectors.

3 RESULTS AND DISCUSSIONS
Global ecosystems contribute to the emission and
capture of CO2, methane (CH4) and nitrous oxide
(N2O), and influence the composition of atmospheric
greenhouse gases and climate. Over the past 50 years,
the removal of approximately one third of
anthropogenic GHG emissions has been associated
with terrestrial ecosystems (Egorova, 2020). In
producing high-quality and large amounts of food for
a growing wealthy population, global food systems
are important sources of GHGs, accounting for more
than one third of global anthropogenic GHG
emissions, of which 71% comes from crop and
livestock production. production systems and land-
use change activities. Forest ecosystems are one of
the most important global carbon sinks and absorb
45% of anthropogenic GHG emissions, with 85–90%
of terrestrial biomass produced in forest ecosystems.
The ocean covers more than 70% of the Earth's
surface and plays an important role in capturing CO2
from the atmosphere. Currently, 22.7% of annual
CO2 emissions from human activities are absorbed by
the ocean ecosystem. To prevent irreversible
deterioration from global climate change, the
biosphere must increase biomass production and food
supply with less greenhouse gas emissions, remove
CO2 from the atmosphere and store it as organic
carbon in the biosphere, contributing to carbon
neutrality. In this sense, we are focusing on
optimizing crop and livestock systems, improving the
health of forest ecosystems through soil carbon
sequestration, and using soils and marine ecosystems
as natural carbon sinks. They can provide
breakthrough technologies for carbon recovery and
immobilization in terrestrial and marine ecosystems,
and they are discussed in more detail in the following
subsections (Meckling, 2020).
Over the past 20 years, greenhouse gas emissions
from agricultural food production systems have
increased by about one-third. Emissions are mainly
related to the growth of crop and livestock
production: 4.2 GtCO2-eq. per year from enteric
fermentation, manure and pasture use and livestock
fuel use, 3.6 GtCO2-eq. per year from the use of
synthetic nitrogen fertilizers and crop production. for
human and animal food and 3.3 Gt CO2-eq. per year
as a result of changes in land use for crop and
livestock systems (Molchanova, 2019; Egorova,
2020). Given the uncertainty associated with the
large-scale deployment of carbon capture and storage
technologies in food production systems, alternative
technologies or approaches are needed to reduce a
significant portion of GHG emissions from
