Yet little attention has been paid to the reverse direction of this relationship, i.e. how agricultural innovation projects affect AIS in the course of their innovative activities. Accordingly, there are currently no tools to measure such AIS spillovers from agricultural innovation projects. OBJECTIVE This paper shows that even where agricultural innovation projects have not been designed with the explicit aim of influencing AIS they can have spillovers on the AIS in which they operate. Based on this finding, it argues that designing agricultural innovation projects in a way that maximises such positive and reduces negative AIS spillovers would be a useful tool for strengthening agricultural innovation capacities in a particular territory or sector. METHODS Based on the concept of agricultural innovation projects as Organisational Innovation Systems (OIS) that are embedded in AIS, the paper develops an analytical framework for assessing spillovers of such projects on AIS and applies it to a case study of an Operational Group in the German Federal State of Hessen. RESULTS AND CONCLUSIONS The case study shows that agricultural innovation projects may yield diverse spillovers on the AIS in which they operate. In addition to considering how agricultural innovation projects are shaped - constrained and/or enabled - by AIS, the research community on agricultural innovation should pay more attention to this side of the interrelation of AIS and agricultural innovation projects. Designing agricultural innovation projects responsibly so that spillovers on AIS are monitored can help to improve national or sectoral AIS. SIGNIFICANCE This paper points to an underexplored issue in research on agricultural innovation and, related to this, a thus far unused potential policy tool for improving national and sectoral AIS. It further develops the concept of innovation projects as OIS into an approach for assessing the effects of projects on AIS; an area of project assessment that until now has not been adequately covered.}, language = {en} } @article{CreamerHagensBaartmanetal.2021, author = {Creamer, Rachel E. and Hagens, Mathilde and Baartman, Jantiene and Helming, Katharina}, title = {Editorial for special issue on "understanding soil functions - from ped to planet"}, series = {European Journal of Soil Science}, volume = {72}, journal = {European Journal of Soil Science}, number = {4}, publisher = {Wiley}, issn = {1365-2389}, doi = {10.1111/ejss.13099}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6870}, pages = {1493 -- 1496}, year = {2021}, language = {en} } @article{MacPhersonVoglhuberSlavinskyOlbrischetal.2022, author = {MacPherson, Joseph and Voglhuber-Slavinsky, Ariane and Olbrisch, Mathias and Sch{\"o}bel, Philipp and D{\"o}nitz, Ewa and Mouratiadou, Ioanna and Helming, Katharina}, title = {Future agricultural systems and the role of digitalization for achieving sustainability goals.

Accordingly, digital agriculture has received considerable attention in policy in recent years, with emphasis mostly placed on the potential of digital agriculture to improve efficiency, productivity and food security, and less attention given to how digitalization may impact other principles of sustainable development, such as biodiversity conservation, soil protection, and human health, for example. Here, we review high-level policy and law in the German and European context to highlight a number of important institutional, societal, and legal preconditions for leveraging digital agriculture to achieve diverse sustainability targets. Additionally, we combine foresight analysis with our review to reflect on how future frame conditions influencing agricultural digitalization and sustainability could conceivably arise. The major points are the following: (1) some polices consider the benefits of digital agriculture, although only to a limited extent and mostly in terms of resource use efficiency; (2) law as it applies to digital agriculture is emerging but is highly fragmented; and (3) the adoption of digital agriculture and if it is used to enhance sustainability will be dependent on future data ownership regimes.}, language = {en} } @misc{WolfNoeltingHammetal.2022, author = {Wolf, Nicole and N{\"o}lting, Benjamin and Hamm, Andrea and Rehak, Rainer and Hobelsberger, Christine and Beer, Felix}, title = {Kommunale Plattformen nachhaltig gestalten : Kriterienkatalog f{\"u}r Plattformen im Dienst einer nachhaltig-digitalen Daseinsvorsorge}, series = {Kurzstudie der Forschungslinie „Zukunftsf{\"a}hige Daseinsvorsorge"}, journal = {Kurzstudie der Forschungslinie „Zukunftsf{\"a}hige Daseinsvorsorge"}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6641}, pages = {54}, year = {2022}, abstract = {Digitale Plattformen avancieren zu einem wichtigen Teil der kommunalen Daseinsvorsorge.

In Germany, the quality of these grasslands is assessed based on the occurrence of certain plant species known as indicator or character species, with indicators being defined at regional level. Therefore, the recognition of these indicators on a spatial level is a prerequisite for monitoring grassland biodiversity. The identification of indicator species for the status quo of grassland using traditional methods was found to be challenging and tedious. Deep learning-algorithms applied to high-resolution UAV imagery could be the key solution, where UAV with remote sensors can map a large area of grassland in comparison to manual or ground mapping methods and deep learning-algorithms can automate the detection process. In this research work, we use an EfficientDet based algorithm to train an object detection model capable of recognizing indicators on RGB data. The experimental results show that this approach is very promising in contrast to the difficult and time-consuming manual recognition methods. The model was trained with the momentum-SGD optimizer with a momentum value of 0.9 and a learning rate of 0.0001. The model was trained and tested on 1200 images and achieves 45.7 AP (and 85.7 AP50) on test data set.

So far, little is known about how the social and ecological conditions of migration interact. Thus, in our study we investigated the rural-urban migration process from the countryside to the capital in the Eastern Steppe conducting semi-structured interviews. Our results show that this rural-urban migration often follows a stepwise process from smaller settlements to larger urban agglomerations. The results also demonstrate a complex interplay between the prevailing social, economic, and ecological factors. While social factors (kinship, education) show the same relevance at each step of migration, ecological factors such as the occurrence of dzud seem more relevant at the early stages, from the steppe to the sum centres. Ecological factors only seem to rank second in importance, after social reasons. Economic reasons are also revealed to be very significant but seem most relevant the closer the migrations are to the capital. These results are essential in order to cope with current and future challenges of population development and find solutions to enable traditional Mongolian nomadism even under a modern lifestyle.}, language = {en} } @article{BerendtBajalanWenigetal.2023, author = {Berendt, Ferr{\´e}ol and Bajalan, Iman and Wenig, Charlett and Hinds, Charlotte and Blaško, Ľubom{\´i}r and Cremer, Tobias}, title = {Estimation of Scots pine bark biomass delivered to the wood industry in Northern Germany}, series = {Central European Forestry Journal}, volume = {69}, journal = {Central European Forestry Journal}, number = {2}, publisher = {Sciendo}, issn = {2454-0358}, doi = {10.2478/forj-2022-0019}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6126}, pages = {89 -- 97}, year = {2023}, abstract = {Scots pine (Pinus sylvestris L.) is the most widely distributed pine species in the world. In Germany, as in many other European countries, it is a very important species both culturally and economically. Few studies have focused on bark volumes being delivered to the wood industry together with the roundwood, being potentially a valuable resource for material or energetic utilization. Therefore, logs from six different forest sites were collected and bark variables including double bark thickness (DBT) in three different categories, diameter, and bark damage (as a degree of miss-DBT) in three different categories, diameter, and bark damage (as a degree of miss-ing bark) were measured and analyzed in order to model bark volume (Vbark) and bark mass (Mbark). The correlation analysis using Pearson's method showed that the highest correlation coefficients were observed from the correla-tion between DBT and Vbark, as well as between DBT and Mbark. Also, results demonstrated that with DBT greater than 20 mm, the percentage of Vbark exceeded 20\%. Finally, different linear regression models were recommended to predict Vbark and Mbark based on the other variables. The results of this study can be used in different wood industries in order to predict bark volume and bark mass of e.g. truckloads or roundwood stacks.}, language = {en} } @article{AmponsemBensahAhiekporetal.2022, author = {Amponsem, Bright and Bensah, Edem Cudjoe and Ahiekpor, Julius Cudjoe and Cremer, Tobias and Herold, Nadine and Antwi, Edward and Mensah, Isaac and Narra, Satyanarayana and Boahen, Benjamin}, title = {Cleaner energy potential analysis for composite biomass residues from decentralized sawmills in Ghana- A case study for Oforikrom Municipality}, series = {Cleaner Engineering and Technology}, journal = {Cleaner Engineering and Technology}, number = {11}, publisher = {Elsevier}, issn = {2666-7908}, doi = {10.1016/j.clet.2022.100563}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6154}, pages = {11}, year = {2022}, abstract = {The variation of wood species processed in sawmills in developing countries generates composite waste which presents treatment challenges due to a lack of understanding of their physicochemical characteristics for proper planning for clean energy generation. Most of the waste is discarded or burnt openly which releases harmful gases into the environment. This study investigated the physicochemical characteristics of mixed sawdust generated from five wood species generated at a Ghanaian sawmill in Oforikrom Municipality for improving waste treatment. The particle size distribution (PSD), bulk density, proximate and ultimate values, thermogravimetric analysis (TGA) and structural analysis were used to characterize the composite sawdust for briquetting and gasification purposes. It was found that the net heating value (17.46 MJ/kg), some proximate and ultimate values meet briquette standard but high percentages of ash (2.95\%), moisture (41.48\%) and the possibility of nitrogen oxides emissions were notable challenges. PSD resulted in different high fine fractions which are unsuitable for densification. The increase of sieving amplitudes at 30, 50 and 80 rpm generated an average increase in sieve efficiency of fines by 4.22\%. Mixing of fines (42.38-46.6\%) and optimum particle size (53.40-57.62\%) fractions was suggested as the best approach to enhance briquette density and durability. The FTIR spectra showed a range of peaks such as 1734.46 cm-1, 1620.48 cm-1, 1506.50 cm-1, 1462.02 cm-1, 1420.32 cm-1 etc. for functional groups identification. Composite sawdust spectra showed high absorbance with no shift of wavenumbers compared with temperate woods, however, it deviated massively when compared with industrial cellulose and organosolv lignin. TGA indicated that exact mixed wood pyrolysis temperatures, volatile and biochar fractions will always depend on sample compositions. The increase in heating rates yielded little significance to volatiles and char increments. Collection of clean sawdust and rooftop drying were recommended as a way of enhancing sawdust properties. Composite sawdust has a promising potential to support Ghana's activities for meeting the renewable energy generation targets. The understanding of these potential assessments is significant to boost the local municipality energy supply.}, language = {en} } @article{Zuberi2021, author = {Zuberi, Mehwish}, title = {Between Disconnects and Flows: Reflections on Doing Fieldwork in Rural South Punjab during the Covid-19 Pandemic}, series = {S{\"u}dasien-Chronik - South Asia Chronicle}, volume = {11}, journal = {S{\"u}dasien-Chronik - South Asia Chronicle}, isbn = {978-3-86004-348-6}, doi = {10.18452/24179}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-6186}, pages = {521 -- 540}, year = {2021}, language = {en} } @article{OrtizJameroCrespinetal.2023, author = {Ortiz, Andrea Monica D. and Jamero, Ma.

Current Nationally Determined Contributions under the Paris Agreement are insufficient to avoid the irreversible loss of critical island ecosystems. Existing research, policies, and finance also do not sufficiently address small islands' social-environmental challenges. For instance, the new Global Biodiversity Framework (GBF) mentions islands in the invasive species management target. This focus is important, as islands are at high risk to biological invasions; however, this is the only GBF target that mentions islands. There are threats of equal or greater urgency to small islands, including coastal hazards and overexploitation. Ecosystems such as coral reefs and mangroves are crucial for biodiversity, coastal protection, and human livelihoods, yet are unaddressed in the GBF. While research and global policy, including targeted financial flows, have a strong focus on Small Island Developing States (SIDS), the situation of other small islands has been largely overlooked. Here, through a review of policy developments and examples from islands in the Philippines and Chile, we urge that conservation and climate change policies place greater emphasis on acknowledging the diversity of small islands and their unique governance challenges, extending the focus beyond SIDS. Moving forward, global policy and research should include the recognition of small islands as metacommunities linked by interacting species and social-ecological systems to emphasize their connectivity rather than their isolation. Coalition-building and knowledge-sharing, particularly with local, Indigenous and traditional knowledge-holders from small islands, is needed to meet global goals on biodiversity and sustainable development by 2030.}, language = {en} } @article{ZellerGoettert2021, author = {Zeller, Ulrich and G{\"o}ttert, Thomas}, title = {Humans, megafauna and landscape structure - Rock engravings from Namibia encourage a comparative approach to central Europe and southern Africa}, series = {Vertebrate Zoology}, volume = {71}, journal = {Vertebrate Zoology}, issn = {1864-5755}, doi = {10.3897/vz.71.e72811}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5538}, pages = {631 -- 643}, year = {2021}, abstract = {This paper deals with reflections that arose after observing prehistoric rock engravings at different locations in Namibia. These observations stimulated comparative considerations with focus on southern Africa and central Europe. Similar to the Aurignacian rock art of European origin, the most common motifs in the Namibian rock engravings are large animals. While in Europe, the species that served as a blueprint for the illustration of Aurignacian rock art have mostly disappeared, the megafauna illustrated on the rock engravings in Namibia can still be found in the immediate vicinity of the rock art. Against this background, we discuss and further develop a comparative regional approach. We reconstruct and evaluate the suitability of African savannas and still-existing megafauna communities as an appropriate reference-frame for natural European grassland systems and extinct associated warm-adapted megafauna (Eemian Interglacial megafauna). Special attention is laid on the unique situation in Africa in the light of a global extinction wave of megafauna following increasing human activity in the Late Quaternary. This leads us to discuss the use of domesticated ungulates as surrogate taxa to fulfill ecosystem functions in Europe as part of concepts termed "rewilding" or "naturalistic grazing". After critically examining these concepts, we conclude that using domesticated forms as representatives of extinct or locally disappeared species in Europe has its justification to some extent. If, however, the naturally occurring megaherbivore community still exists (Africa), these naturally occurring species should be given priority due to their organismic abilities and limitations adapted to the harsh conditions in their specific environment. Finally, we discuss the application of (transboundary) protected areas as effective instruments to mitigate human-wildlife conflicts. A holistic approach, including nature conservation and preservation of cultural achievements (domesticated forms, grazing systems), appears promising for the effective protection of the natural African savanna ecosystems with their unique fauna elements, as illustrated in rock engravings that inspired us to write this paper.}, language = {en} } @inproceedings{SchroederGuerickeKoerner2021, author = {Schr{\"o}der, Jens and Guericke, Martin and K{\"o}rner, Michael}, title = {Fingerprints of biotic agents in tree-ring and NDVI time series of forest stands}, series = {TRACE - Tree Rings in Archeology, Climatology and Ecology - Virtual Conference 2021}, booktitle = {TRACE - Tree Rings in Archeology, Climatology and Ecology - Virtual Conference 2021}, doi = {10.13140/RG.2.2.17808.33286}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:eb1-opus-5559}, pages = {1}, year = {2021}, language = {en} } @misc{WelleIbischBlumroederetal.2021, author = {Welle, Tobias and Ibisch, Pierre L. and Blumr{\"o}der, Jeanette Silvin and Bohr, Yvonne E.-M.
