Data or statistical facts on the situation and perspectives of agri-food systems and the impact of policies
28 % of agricultural land in low-income countries, 40 % in lower-middle, 85 % in upper-middle and 99 % in high-income countries are farms larger than 5 ha (Lowder et al., 2021).
Almost 50% of studies on climate resilient crops identify extension services as a factor for successful adoption (Laborde, 2020).
More than 1 billion people depend on livestock as a means of subsistence (Laborde, 2020).
80% of terrestrial carbon is in the lithosphere and fossil fuels, while the remaining 20% is in the ocean, atmosphere, living organisms and soil (Cady, 2020).
33% of anthropogenic emissions are offset by increased photosynthesis, 22% is absorbed by the ocean and 45% remains in the atmosphere (Cady, 2020).
8.6 years is the half-life of methane in the atmosphere (Cady, 2020).
100 times faster is the current increase in atmospheric CO2 compared to the natural increase at the end of the last Ice Age between 11,000 and 17,000 years ago (Lindsey, 2018).
95% of anthropogenic CO2 emissions come from burning coal, oil and natural gas (Cady, 2020).
40% of the world's land area and 70% of water use are used for agriculture (OECD, 2020).
14.5% of global greenhouse gas emissions, equivalent to 7.1 gigatons of CO2 per year, come from livestock chains.
