Food demand, Productivity Growth and the Spatial Distribution of Land and Water use: A Global Modelling Approach

Nowadays, human society appropriates about one quarter of total net primary production of the terrestrial biosphere. Production of food, energy and materials, and the related use of land and water account for crucial components and interactions in the Earth System. However, rising food, energy and material demand, climate change and ambitious mitigation policies will enhance the competition for land and water. While the combined impacts of these drivers are still highly uncertain, global land-use patterns will change in the future, reacting to these pressures. Projecting their future development is important to study both, their impacts on the Earth System as ...

Data-Model Fusion Approach in Global Change Research: Recent Development and Future Challenges

It is increasingly recognized that global change research requires methods and strategies for combing process models and data in systematic ways. This is leading to research towards the application of model-data fusion approach. The model-data fusion is a new quantitative approach to model analysis and data assimilation that provides a high level of empirical constraint over model predictions based on observations. Applications of model-data fusion require (a) a model that describes the underlying physical, chemical and biological processes, (b) experimental observations and (c) an optimization tool. The optimization tool is used to find optimal estimates of model parameters or states ...
