    Greenhouse gas emissions and global warming potentials of five paludiculture plants in fen peatlands in southern Germany (2023) Beitrag auf der EGU General Assembly, Mai 2023 .

    The concept of paludicultures is growing in importance as a promising climate mitigation measure and a sustainable alternative to current agricultural use of organic soils. Besides agricultural and economic viability, quantifying the climatic effects of paludicultures is essential to give reliable policy advice and facilitate sustainable management decisions with regard to climate change. Emission factors (EFs) of the relevant greenhouse gases (GHG) carbon dioxide (CO 2), methane (CH 4) and nitrous oxide (N 2 O) for a variety of potential paludiculture plants are still rare, especially from comparable treatments and site conditions. Five different temperate fen plant species (Carex acutiformis, Phragmites australis, Phalaris arundinacea, Typha latifolia and T. angustifolia) were established as paludicultures with one or two-cut harvest frequencies at three former grassland or arable sites on fen peatland in southern Germany. Ground water levels (gwl) were manipulated to generate a water table gradient spanning annual mean gwl between +4 to −22 cm to derive an optimum gwl for GHG mitigation. One to five years after plant establishment, we measured fluxes of CO 2 , CH 4 and N 2 O to obtain annual budgets (n=81 / 43 rewetted: gwl +4 to −10 cm, 38 moderately rewetted: gwl −11 to −22 cm) using manual and automatic closed chambers. Besides gas flux measurements, we observed vegetation growth parameters (LAI, NDVI) and biomass yield from harvests. The resulting mean global warming potentials are −13.0 ± 13.9 t CO 2-eq ha −1 yr −1 under rewetted conditions (annual mean gwl ≥ −10 cm) and −1.0 ± 9.8 t CO 2-eq ha −1 yr −1 under moderately rewetted conditions (annual mean gwl < −10 cm). Our dataset revealed that a maximum mitigation potential of paludicultures is achieved at a gwl of −7 cm. These values represent the first EFs of paludicultures for potential integration into the German national GHG inventory. Powered by TCPDF (www.tcpdf.org)

    Geodesign as Online Teaching Method – Lessons from a Multiple Case Study (2023) JoDLA – Journal of Digital Landscape Architecture (8), S. 598-607. DOI: 10.14627/537740063

    This study analyses the geodesign workshop as a method for the online teaching of group work methods in the context of geoinformation systems (GIS) in planning and design. In order to assess the learning outcome, four workshops with international landscape architecture students at master level were conducted over a period of four years (2018-2021) and compared in a qualitative multiple-case study. In times of Covid-19 and the need for remote workshop methods, the geodesign workshops seem well suited for online learning and teaching. The results show that the learning goals were achieved, that new ideas were created and stakeholder expectations reflected and challenged. In individual cases, the lack of on-site knowledge led to mistakes though, and online group work had different group dynamics than in-person negotiations. Vocal and well-organised students seem to engage even more whereas quiet students more easily disengage, as seen in a bimodal distribution of participation grades in the online class. In conclusion, geodesign workshops may be recommended as an online method for teaching GIS and group work methods such as brainstorming, consensus building and stakeholder-role play but a hybrid format or new virtual field trip techniques are preferable when familiarizing students with the case study site. The teaching of group work methods as part of planning and design may be transferred from geodesign to teaching building information models, which is also an information-based digitally facilitated collaboration process.
