Stakeholders, Interests and Power as Drivers of Community Forestry: Comparative Analysis of Albania, Germany, Cameroon, Indonesia, Namibia, Nepal and Thailand (Project)
Community forestry has not met the great public expectations on a significant contribution to sustainable forestry yet. Recent research in the management and policy of community forestry describes a complex process of multi level social choice which determines the outcomes. Our hypothesis is that the key factors determining the outcomes of community forestry are the interests and power of the...

Stabilization of organic matter by complexation or precipitation with aluminum: effect of the size of the complexes formed and flakes (Project)
From soil solutions of acidic forest soils, up to 90% of organic matter (OM) can be precipitated by Al. Precipitation of OM contributes to its stabilization against microbial decay. Thus, this process should be of major relevance for C cycling and sequestration, but little is known about the properties and the composition of precipitated OM. Furthermore, it is still unclear whether Al reduces C...

Collaborative project: Biotechnological based breeding strategy to strengthen the resistance of barley against Ramularia - Subproject 4 (Project)
In a cooperation of five barley breeding companies and three research groups conditions were to be set out for the breeding of barley with improved resistance to the fungal pathogen of Ramularia collo-cygni (RCC). A whole-plant test, a leaf-segment test, and a RealTime- PCR protocol for RCC-DNA detection were established to quantify infestation of plants with RCC. A screening of 40 spring barley...

Sequestration of carbon in soils: Mechanisms and type of fixation (Project)
Up until the eighties of last century the dynamic of soil organic matter (humus) was mainly considered under the aspect of soil fertility. In recent times this soil compartment attracted new attention as a sink and source of CO2. In regard to the increase of CO2 in the atmosphere it has been assumed that suitable agricultural practices can lead to an additional fixation of carbon in soils. The...

Assessment of the fluxes of reactive trace gases, aerosol constituents and sedimenting particles between the atmosphere and agro-ecosystems (Project)
The monitoring of fluxes of those trace gases and aerosol constituents for which automatic analyzers (with a high resolution in time using optical properties of the species considered) are not available has to make use of concentration measurements using denuders and/or filters and combine them with micrometeorological models. The FAL site is one of the very few locations in Europe with adequate...

Application of stable Carbon-, Nitrogen- and Sulphur isotopes to characterise and indicate fluxes in agricultural systems under different land use and environmental conditions (Project)
Carbon (C), nitrogen (N) and sulphur (S) naturally occur with several stable isotopes of different masses. The relative abundance of these isotopes is different and they are turned over in biological, chemical and physical processes at different rates. Hence pools of different isotopic composition develop and depending on their origin and history, C-, N- and S- containing substances differ in...
