Digital Soil Mapping and Assessment (DSMA) has progressed from challenging traditional soil science paradigms, through small scale prototyping, to large-scale implementation capturing quantitative measures of soil attributes and functions. This paper considers the future for DSMA in the context of a highly uncertain world where high-quality knowledge of soil dynamics will be important for responding to the challenges of sustainability. Irrespective of whether the need is for survival, increased productivity or broadening the services provided from land management, or simply securing the soil itself, we see DSMA as a fundamental approach and essential tool. With a broadening need and a strong foundation in the practice of DSMA now in place, the theory, tools and technology of DSMA will grow significantly. We explore expected changes in covariate data, the modelling process, the nature of base data generation and product delivery that will lead to tracking and forecasting a much wider range of soil attributes and functions at finer spatial and temporal resolutions over larger areas, particularly globally. Equally importantly, we expect the application and impact of DSMA to broaden and be used, directly and collaterally, in the analysis of land management issues in coming decades. It has the capacity to provide the background to a soil and landscape ‘digital twin’ and the consequent transformation in monitoring and forecasting the impacts of land management practices. We envision the continued growth of DSMA skills amongst soil scientists and a much broader community of practice involved in developing and utilizing DSMA products and tools. Consequently, there will be a widening and deepening role of public-private partnerships in this development and application.

数字土壤测绘和评估（DSMA）已从具有挑战性的传统土壤科学范式发展到了小规模的原型制作，再到大规模实施，以定量的方式测量土壤的属性和功能。本文考虑了在高度不确定的世界中DSMA的未来，在该世界中，高质量的土壤动力学知识对于应对可持续性挑战至关重要。无论是生存，提高生产力还是扩大土地管理部门提供的服务，或者仅仅是保护土壤本身，我们都将DSMA视为基本方法和重要工具。随着对DSMA实施的广泛需求和坚实基础，DSMA的理论，工具和技术将显着增长。我们探索了协变量数据，建模过程，基础数据生成和产品交付的性质的预期变化，这些变化将导致在更大的区域（尤其是在全球范围内）以更精细的时空分辨率跟踪和预测更广泛的土壤属性和功能。同样重要的是，我们希望DSMA的应用和影响能够在未来几十年中扩大并直接和附带地用于土地管理问题的分析。它有能力为土壤和景观“数字孪生”提供背景知识，并为监测和预测土地管理实践的影响提供相应的转换。我们设想土壤科学家以及开发和利用DSMA产品和工具的广泛实践社区中DSMA技能的持续增长。
