Promoting sustainable land management is key to addressing land degradation but its progress is impeded by the availability and accessibility of the ‘right’ soil data and information. We focus on government-funded data collection or publicly collected soil data as it is central to effective soil governance. Taking a governance perspective, we discuss what soil information is created and used for, who are the actors involved and how soil information is contributing (or not) to the creation of actionable knowledge. We investigated two countries in depth through a desk-based review and consultation with 40 key informants, collating which soil data and information is collected, analysed, stored, retrieved and used in the UK and Australia. We present a comprehensive overview of public soil databases, including location, year established, stated purpose, current governing institution, accessibility, digital product/s available, cycle of assessment, scale of sampling, soil data presented and depth of soil assessment. The analysis highlights that current shortcomings in soil governance are a result of not adequately valuing legacy soil data and information, and with the loss of human capital, diminished accessibility to soil information leads to disrupted information flows. A critical assessment suggests that available soil information plays a limited role in knowing the soil types of a locality, the condition of soil under various land uses and associated management, which limits its potential for informing sustainable land management. In both countries, there is a mismatch in scale and intention of use for the soil information between the provider and the user: information is currently held at the scale for regional- or nation-level reporting on targets to meet national and international obligations rather than improving soil health or SLM at the farm scale. In addition, available soil data repositories only partially meet accessibility criteria (discoverability, language applicable to audience, open source and interpretative layer for land management implications). We outline steps to improve soil information and knowledge exchange embedded in effective governance arrangements to ensure that soil data and information can become actionable knowledge for SLM. Applying principles and strategies for facilitating knowledge exchange is of particular relevance to this process.
