"The long-term effects of soil erosion: a global economic analysis"
by Sartori, Martina, Kirsten Boysen-Urban, Emanuele Ferrari, George Philippidis, Robert M'barek, Pasquale Borrelli and Luca Montanarella


Abstract
This study employs an interdisciplinary approach to assess the long-term structural economic and non-economic impacts of soil erosion at the global scale. Country-level estimates of soil erosion at the year 2070 are then converted into land productivity losses, to feed the Modular Applied GeNeral Equilibrium Tool (the MAGNET global CGE model) (Woltjer and Kuiper, 2014), recently enriched with several non-market indicators (land usage, GHG emissions, water abstraction, SDGs). Future rates of global soil erosion (Borrelli et al. 2020) are predicted by the high spatial resolution Revised Universal Soil Loss Equation (RUSLE)-based semi-empirical modelling approach under three alternative combinations of Shared Socioeconomic Pathway and Representative Concentration Pathway (SSP-RCP) scenarios (i.e., SSP1-RCP2.6, SSP2-RCP4.5, and SSP5-RCP8.5).
For each single region considered, the study will show the impact of future soil erosion on national income, agricultural markets, international food prices and food security, as well as land and water use change, and the most relevant SDG indicators.
