Last week the Intergovernmental Panel on Climate Change (IPCC) released its Special Report on Climate Change and Land, a document authored by 107 experts from 52 countries. It warned that “Land is a critical resource.”
The main conclusion of the report is that humans already use nearly half of the planet’s land for food production and, as global population levels rise, agricultural land is going to be in very short supply. This is because one of the effects of climate-change will be a decline in agricultural productivity across the tropics, meaning that we will need to cut down forests and convert unused land into farmland. This deforestation will lead to even more carbon emissions, culminating in a vicious cycle of increasing warming.
