Abstract (englisch):
As the applications of Earth system models (ESMs) move from general climate pro- jections toward questions of mitigation and adaptation, the inclusion of land man- agement practices in these models becomes crucial. We carried out a survey among modeling groups to show an evolution from models able only to deal with land- cover change to more sophisticated approaches that allow also for the partial inte- gration of land management changes. For the longer term a comprehensive land management representation can be anticipated for all major models. To guide the prioritization of implementation, we evaluate ten land management practices—for- estry harvest, tree species selection, grazing and mowing harvest, crop harvest, crop species selection, irrigation, wetland drainage, fertilization, tillage, and fire—for (1) their importance on the Earth system, (2) the possibility of implementing them in state-of-the-art ESMs, and (3) availability of required input data. Matching these criteria, we identify “low-hanging fruits” for the inclusion in ESMs, such as basic implementations of crop and forestry harvest and fertilization. We also identify ... mehr
