New challenges and policy developments after 2015 (among others, the Common Agricultural Policy (CAP), Sustainable Development Goals (SDGs)) are opportunities for soil scientists and soil erosion modellers to respond with more accurate assessments and solutions as to how to reduce soil erosion and furthermore, how to reach Zero Net Land Degradation targets by 2030. This special issue includes papers concerning the use of fallout for estimating soil erosion, new wind erosion modelling techniques, the importance of extreme events (forest fires, intense rainfall) in accelerating soil erosion, management practices to reduce soil erosion in vineyards, the impact of wildfires in erosion, updated methods for estimating soil erodibility, comparisons between sediment distribution models, the application of the WaTEM/SEDEM model in Europe, a review of the G2 model and a proposal for a land degradation modelling approach. New data produced from field surveys such as LUCAS topsoil and the increasing availability of remote sensing data may facilitate the work of erosion modellers. Finally, better integration with other soil related disciplines (soil carbon, biodiversity, compaction and contamination) and Earth Systems modelling is the way forward for a new generation of erosion process models.
2015 年后的新挑战和政策发展（包括共同农业政策（CAP）、可持续发展目标（SDGs）等）为土壤科学家和土壤侵蚀模型师提供了机会，他们可以更准确地评估如何减少土壤侵蚀，并进一步制定到 2030 年实现零净土地退化目标的解决方案。本期特刊包括关于使用沉降物估算土壤侵蚀、新的风蚀建模技术、极端事件（森林火灾、强降雨）在加速土壤侵蚀方面的重要性、减少葡萄园土壤侵蚀的管理实践、野火对侵蚀的影响、更新的土壤可蚀性估算方法、沉积物分布模型比较、WaTEM/SEDEM 模型在欧洲的应用、G2 模型的回顾以及提出一种土地退化建模方法的论文。从 LUCAS 表土等实地调查中获得的新数据以及遥感数据的日益普及，可能会为侵蚀模型师的工作提供便利。最后，更好地与其他与土壤相关的学科（土壤碳、生物多样性、压实和污染）以及地球系统建模进行整合，是新一代侵蚀过程模型的发展方向。
