What does this graph show us

Shows how deep you should flood when reflooding. a lot like the other graph from previous question To shallow - co2 eimissons To deep - upper surface is anerobic so methane is released. So we want it to fluctuate around the surface. If the upper 10 cm stays oxidised. Then methane oxidisers can work and less emissions. In denmark they do the middle one but they don't pay the farmers. Paludiculture - is allowing farmers to grow crops on drained peatlands which can grow in flooded conditions. Then they are corbon sinks and farmers can make money. Then you can grow reeds.
