SFB/TRR 32 Project D1 : Modelling of time-space patterns of energy and mass fluxes over heterogeneous land surfaces with special consideration of CO2 and H2O (Project)
The project tries to answer the question, how are heterogeneous surface patterns displayed in the fields of specific humidity and carbon dioxid in the atmosphere. Tools to reach this goal are meso/microscale modelling and area covering airborn measurements. While the measurements will be done in project D2, in D1 the main focus will be put on modelling with a non-hydrostatic model with a...

SFB/TRR 32 Project D2 : Experimental study of spatio-temporal structures in atmosphere-land surface energy, water and CO2 exchange (Project)
Land surface–atmosphere exchange of energy and momentum but also of water and CO2, is highly variable in space and time. In order to identify spatial and temporal patterns of exchange parameters, an experimental framework will be established which combines continuous ground based in situ measurements with state-of-the-art remote sensing observations and dedicated aircraft campaigns within the Rur...

SFB/TRR 32 Project D3 : CO2-and water flux estimation by four-dimensional variational assimilation of in situ and remote sensing data (Project)
The project section aims to provide highly resolved optimal flux estimations of CO2 and water between the atmosphere and soil/vegetation under the influence of heterogeneous, but structured surface patterns and organized atmospheric processes. The project intends to apply advanced spatio-temporal data assimilation methods as key technique, to combine all available information from models,...

SFB/TRR 32 Project Z1 : Project Database and Data Management (Project)
Data storage and exchange in interdisciplinary research projects, which focus on field studies and modelling, is a key issue. The overall success of such projects depends on the well organized data management and data exchange. Therefore, the aim of this project section is to solve the main problems of data storage and exchange within an interdisciplinary project by using a database which allows...

Analysis of resistance to powdery mildew of grapevine on genomic level (Project)
The project is aimed at the identification of genes involved in pathogen defense in Vitis species. Extended information about resistance loci based on genetic mapping using anonymous markers have already been accumlated for Muscadinia at Colmar and Evry and for Regent at Geilweilerhof. Thus, candidate cDNAs from both sources are to be identified by transcriptional profiling within the scope of...

SFB 552: A4 - Socioeconomic analysis of land use systems of rural households (Project)
Project A4 investigates trade-offs and synergies between economic growth, poverty reduction, and environmental objectives. Its research findings show that 20.6% of the households in the research area live on less than 1 US$ PPP capita-1 day-1. Poorer households have less access to credit markets and live in locations with poorer market and road infrastructure, where lower prices and higher price...

SFB 552: A5 - Welfare economic assessment of forest encroachment and ENSO effects in the face of Personal Capital and Social Capital dynamics (Project)
A5 assesses marginal bet benefits along a rainforest conversion gradient. We upscale existing local data to the project area, close remaining data gaps, and take the dynamics of the economic system into account. The valuation methodology on ecosystem conversion is compatible with the standards set out by Balmford et al. (2002), which have to date been met only by two studies on rainforest...

SFB 552: A6 - Poverty, gender, and vulnerability at regional and intra-household level (Project)
This project analyses the role of non-agricultural incomes and household and intrahousehold dynamics on the use of forest resources by poor households at the rainforest margins. The project will use panel data and appropriate techniques to understand: the role of non-farm incomes in affecting poverty and resource use; the role of demographic and other shocks on poverty, vulnerability and...

SFB 552: B1 - Energy and mass exchange between atmosphere and tropical ecosystems (Project)
In B1 H2O-, CO2- and energy fluxes between the atmosphere and a natural rain forest and other land use types relevant in the rain forest margin zone will be quantified by field measurements and by numerical modelling, so that water availability, and CO2- fluxes, plant production and local climate influences can be assessed. A meteorological network will be run to regionalize atmospheric...

SFB 552: B4 - Drought effects on soil water regime and water partitioning in cacao agroforest (Project)
The main objectives of this sub-project are (1) to analyse the rates and depths of soil water depletion in natural forest and agroforest, (2) to study separately the water use and partitioning of shade trees and cacao plants in the agroforestry system, and (3) to test for both land use systems whether hydraulic redistribution is an important mechanism to cope with drought. The results shall help...
