This set of SSP land-use scenarios provides a comprehensive quantification of interacting trends in the land system, both socio-economic and biophysical. Expansion of agriculture for food production is reduced due to REDD policy (290 Mha in 2050) affecting food security especially in Sub-Saharan Africa indicating an important trade-off of land-based mitigation. This is achieved by expansion of bioenergy area (516 Mha in 2050) and reforestation. Second, bioenergy and reforestation are crucial to create net negative emissions reducing emissions in SSP2 in 2050 by 8.7 Gt CO2/yr and 1.9 Gt CO2/yr, respectively (1.5 ☌ scenario compared to baseline). First, agricultural emissions could form a substantial component of emissions that cannot be fully mitigated. Land use also plays a crucial role in ambitious mitigation scenarios. With low increases in agricultural efficiency this leads to expansion of agricultural land and reduced food security. The largest changes take place in Sub-Saharan Africa in SSP3 and SSP4, predominantly due to high population growth.

Key drivers are population growth, changes in food consumption, and agricultural efficiency. Grid Drawing Train Drawing, Image Originale, Art Plastique, Moleskine, Art Reference. Results show diverging global trends in agricultural land in the baseline scenarios ranging from an expansion of nearly 826 Mha in SSP3 to a decrease of more than 305 Mha in SSP1 for the period 2010–2050.

To investigate these dynamics, this paper describes five elaborations of the Shared Socio-economic Pathways (SSP) using the IMAGE 3.0 integrated assessment model framework to produce regional and gridded scenarios up to the year 2100. Photos help us to remember beautiful moments. Ambitions to limit global warming to 2 ☌ or even 1.5 ☌ could also lead to additional pressures from land-based mitigation measures such as bioenergy production and afforestation. Projected increases in population, income and consumption rates are expected to lead to rising pressure on the land system.
