Session 3c: Mapping and monitoring of soil organic matter

Chair:   Keith Shepherd (World Agroforestry Centre ICRAF, KE)

There is interest in mapping and spatial monitoring soil organic matter for different purposes and at different scales. Establishing baselines and monitoring of soil carbon stocks is of interest up to global scales for understanding the global carbon cycle, and down to project and farm scale for certifying carbon payment schemes. Measuring organic matter concentrations in soils is of interest to ensure levels are maintained at a level that upholds essential soil ecosystem functions and for the design and implementation of schemes for rewards for environmental services. Behind all of these objectives is a need for valid sampling schemes, reproducible measurement protocols, robust statistical methods, and economic viability in relation to a particular decision problem. There are increasing opportunities for leveraging remote sensing data and new field and lab sensors to reduce costs. This session encourages examples of soil organic matter mapping and monitoring schemes that have led to effective decision support.
