Structure and Functions of Agricultural Landscapes under Global Climate Change - Processes and Projections on a Regional Scale
Contract period : - 2011
The Integrated DFG Project 'Regional Climate Change' consists of eight subprojects bringing together researchers from Hohenheim and Munich. It aims at clearing up the effects of global climate change on structure and functions of agricultural landscapes on a regional scale. Projections of their development will be made for the period until 2030, taking into consideration different socio-economic scenarios and adaptation processes.
In order to meet this joint objective it will be essential to integrate regional climate, land surface, and crop models as well as multi-agent systems into a land system model and to improve the structure and parameterisation of various components. Field measurements and controlled exposure experiments will be conducted in order to improve various model components and their parameterisation and to validate individual models and the coupled model system.
Our investigations will be exemplified for two study areas in Southwest Germany: 1) an intensively used agricultural landscape (Kraichgau), characterised by mild climate and moderate precipitation, and 2) an extensively used agricultural landscape (Mittlere Schwäbische Alb), which shows higher precipitation because of orographic effects and lower mean temperatures as a consequence of its altitude. Results and conclusions obtained for these two study regions will be exemplary for extended agricultural landscapes in Germany and Central Europe. (DFG Project PAK 346).
The follow-up project is the DFG-Researchgroup 1695 with the title 'Agricultural Landscapes under Global Climate Change – Processes and Feedbacks on a Regional Scale'.
