The report covers challenges such as desertification, land degradation, food security and impacts of climate change on greenhouse gas (GHG) fluxes from terrestrial ecosystems. The main focus of the report is particularly on the entire chain of food production and consumption. According to the IPCC, the “human use directly affects more than 70 % of the global, free land surface” and agriculture and forestry account for around 23 % of GHG. Researchers of the IPCC report that “human activities” have led to depleted soils, the expansion of deserts, the disappearance of forests and the drainage of peatlands. In particular, the production and the increasing consumption of red meat – primarily beef and pork – is extremely problematic for the global climate, as methane gas is emitted by the masses of animal feed that have to be produced.
Researchers of the IPCC hope that the issue of land use will become more in the focus of international negotiations on the climate crisis and demand appropriate support and collaboration of multiple stakeholders at all scales to enable land-related adoption and mitigation to climate change.
