This paper describes how a new cloud-based Land-Potential Knowledge System (LandPKS; www.landpotential. org; figure 1) will allow land potential to be defined explicitly and dynamically for unique and constantly changing soil and climate conditions and to be updated based on new evidence about the success or failure of new management systems on different soils. The knowledge engine (figure 2), together with simple applications for mobile phones, will also facilitate more rapid and complete integration and dissemination of local and scientific knowledge about sustainable land management.
