Changing greenhouse gas emissions with groundwater table variation

Controlled drainage and active water management are climate smart options for agricultural production on organic soils under current and future climatic conditions. We propose that wet organic soils can be used as risk insurance in dry periods while active water and soil management will improve trafficability. Peat degradation can be reduced and water availability in dry summers increased. Alternative, wetness-adapted crops with stable yield quantity and quality are needed to meet requirements for food, feed and bioenergy. The CAOS project aims to generate the knowledge to design climate smart agricultural systems for organic soils adapted to the diverse regional conditions of Northern and Central Europe. CAOS will provide and distribute evidence that active management aiming at a better control of groundwater levels, improved trafficability and alternative high productivity crops improves yield stability and quality as well as resilience to climate change while providing GHG mitigation and improved soil and water quality.
