Similarly, indigenous peoples living in mountainous areas will suffer a depletion of
food sources owing to the loss of alpine flora. Coastal erosion on Pacific islands is
threatening agricultural practices while traditional cattle and goat farming is being
endangered in arid regions. There is considerable concern that the impacts of
climate change may overstrain indigenous and traditional peoples ’ capacity to cope
and adapt (A/HRC/29/19).
V. Impact of agriculture and food systems on climate change
41. The previous sections illustrate how climate change can undermine the right to
food. The following section will provide an overview of the ways in which
agriculture and food systems can negatively affect climate change, endangering the
full enjoyment of the right to food.
Greenhouse gas emissions
42. The food system as a whole is a significant contributor of greenhouse gas
emissions. Crop and livestock agriculture currently account for about 15 per cent of
global emissions. 32 Direct greenhouse gas emissions from agriculture include
methane (CH 4 ) emissions from flooded rice fields and livestock, nitrous oxide
(N2 O) emissions from the use of organic and inorganic nitrogen fertilizers and
carbon dioxide (CO 2 ) emissions from loss of soil and organic carbon in croplands as
a result of agricultural practices and in pastures as a result of increased grazing
intensity. 33 In addition to these direct emissions, agriculture and food production are
also responsible for an increase in indirect emissions that are accounted for in other
sectors (industry, transport, energy supply, etc.), which can misleadingly understate
the environmental footprint of agriculture. The production of fertilizers, herbicides
and pesticides as well as energy consumption for tillage, irrigation, fertilization,
harvesting and transport contribute to 60 per cent of total food system emissions
globally, although there is significant regional variation. The expansion of
agricultural areas and changes in land use contribute an additional 15 -17 per cent of
emissions. It is further estimated that future income and population growth will
increase agricultural emissions dramatically unless low-emissions growth strategies
for agriculture are found. 34
Role of livestock
43. The world’s current consumption pattern of meat and dairy products is a major
driver of climate change and climate change can only be effectively addressed if
demand for these products is reduced. Livestock systems are the source of 33 per
cent of the protein in human diets, while 30 per cent of land worldwide is used to
