- The IPCC report highlights the vicious cycle of climate change and land degradation
- Land use produces almost a quarter of the world's greenhouse gas emissions
- To stave off the worst effects of climate change, humans need to stop converting land
The warning comes almost a year after the Intergovernmental Panel on Climate Change (IPCC)
concluded in a landmark report that we only have until 2030
to drastically reduce our dependence on fossil fuels and prevent the planet from reaching the crucial threshold of 1.5 degrees Celsius above pre-industrial levels.
The second IPCC report highlights the vicious cycle of climate change and land degradation.
"We humans affect more than 70% of ice-free land, a quarter of this land is degraded. The way we produce food and what we eat contributes to the loss of natural ecosystems and declining biodiversity," said Valérie Masson-Delmotte, co-chair of the IPCC.
Climate change increases the frequency and intensity of droughts
, flooding and heat waves, which can irreversibly destroy natural ecosystems and lead to food shortages.
Deforestation and agriculture also fuel global warming, by weakening land's capacity to draw down carbon dioxide from the atmosphere and emitting vast amounts of greenhouse gases.
