I have seen how bad carbon forestry (as climate mitigation) works on the ground in Africa. How poor pastoralists loose their livelihoods and wildfire risk increases when traditional grazing and burning is excluded. Even though conserving the last remnants of old-growth forests is necessary. The carbon focus and the anticipated large funds for this corrupts conservation. And I saw my own carbon budget, after omitting almost everything, except work flights.
Fire ecology, interactions between livestock and fire regimes, especially in semi-natural wooded pastures in Africa. Relations between nature and traditional land use in subalpine heathlands and forests and wooded savannas in Ethiopia.
