Research on soil erosion expanded progressively throughout the 20th centu\ry, although a number of unresolved problems persist despite this issue being crucial for the environment and the welfare of society. Some basic unresolved issues, including the absence of a universally accepted definition of soil erosion and disagreement about how to measure it have contributed to a degree of scientific stagnation. Accurate prediction of the response of soils to disturbance is hampered by the dependence of the erosion process on the spatial scale involved, the time lag between the disturbance and the erosion response and the short periods for which data are typically available. We argue that devoting increased attention to the following environmental, demographic, political and societal issues will reinvigorate progress in the field. (i) The relationships between on-site and off-site consequences of soil erosion need to be elucidated if the economic and environmental costs are to be adequately assessed. (ii) Effective measures for soil conservation need to focus on spatial patterns of plant cover that reduce sediment connectivity, and most importantly on the relationships between hillslopes and sediment transfer in eroded channels. (iii) The scientific community must be able to identify early warning signs of critical transitions, if irreversible soil degradation is to be prevented. (iv) Consensus needs to be reached concerning the contribution of soil erosion to the carbon cycle. (v) The consequences of climate change on erosion and sediment transport should be investigated in depth. (vi) The general society needs to perceive soil erosion as a critical matter requiring an urgent response. 000079365 536__ $$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/CGL2015-65569-R$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/CGL2011-27753-C02-02$$9info:eu-repo/grantAgreement/ES/MINECO-FEDER/CGL2011-27753-C02-01$$9info:eu-repo/grantAgreement/EC/FP7/ 603498/EU/Preventing and Remediating degradation of soils in Europe through Land Care/RECARE 000079365 540__ $$9info:eu-repo/semantics/openAccess$$aAll rights reserved$$uhttp://www.europeana.eu/rights/rr-f/ 000079365 590__ $$a7.27$$b2017 000079365 591__ $$aSOIL SCIENCE$$b1 / 34 = 0.029$$c2017$$dQ1$$eT1 000079365 591__ $$aENVIRONMENTAL SCIENCES$$b8 / 241 = 0.033$$c2017$$dQ1$$eT1 000079365 592__ $$a1.761$$b2017 000079365 593__ $$aDevelopment$$c2017$$dQ1 000079365 593__ $$aSoil Science$$c2017$$dQ1 000079365 593__ $$aEnvironmental Science (miscellaneous)$$c2017$$dQ1 000079365 593__ $$aEnvironmental Chemistry$$c2017$$dQ1 000079365 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000079365 700__ $$aBeguería, Santiago 000079365 700__ $$aLana-Renault, Noemí 000079365 700__ $$0(orcid)0000-0002-4651-7828$$aNadal-Romero, Estela$$uUniversidad de Zaragoza 000079365 700__ $$aCerdà, Artemi 000079365 7102_ $$13006$$2430$$aUniversidad de Zaragoza$$bDpto.
