Technical procedures for closed crop production systems to reduce greenhouse gas emissions and climate change-induced abiotic stress

One of the major challenges of the 21 st century is the mitigation of global climate change,
which is mainly caused by greenhouse gas emissions. One contribution to this could be made
by advanced and intelligently controlled greenhouse systems. Therefore, the main objective of
the forthcoming project, with four project partners, is to develop and optimize innovative
technical procedures for the greenhouse system as a whole. This will be done not only to
achieve a substantial reduction in greenhouse gas emissions, but also to reduce the
consumption of freshwater and fertilizer recourses. This goal is in the context with the
optimization of microclimatic conditions, such as temperature, relative humidity, light
intensity and quality as well as CO 2 concentration, in the closed plant production system to
ensure the high-quality food supply to the population regardless of the climatic changes. The
research is especially focussed on the finding of an optimal cooling process, the development
of new outdoor climate-adapted CO 2 , light and nutrient solution control strategies, as well as
new substrates and substrate-less culture systems for closed greenhouse system, taking into
account the reduction of abiotic stress factors in times of increasing variability of climatic
conditions. Within the frame of investigations on the changes of the phenotype caused by the
technical procedures, online measured phytosignals (photosynthesis, transpiration, leaf
temperature, stomata conductance, chlorophyll fluorescence etc.) and laboratory analyses are
parts of this project to detect changes in the primary and secondary metabolism of plants and
associated changes in product quality and quantity.
