9th CASEE Conference - Session 1

Session 1: Modern agriculture and rural development

Chairs:

Prof. Dl Dr. Dr.h.c. mult. Martin H. Gerzabek, BOKU, Austria
Prof. univ.dr. Florin Stănică, USAMV, Romania

Nine oral presentation and ten posters comprised this lively, and well received session. Pia Euteneuer released an excellent talk about the decomposition of sclerotia in soil, the impact of season and specifically earthworms – a finding by chance during a flood event. Otilia Bobis elucidated concepts and strategies to improve leave and fruit quality of mulberries for silk worm breeding, a significant economically sound activity for rural areas. Lucia Pop explained the complete value chain for silk production in Romania and focussed specifically on the re-establishment of mulberry tree plantations and the subsequent sericultural and silk technology. Michael Pillei elaborated the concept of an university network within CASEE, dedicated to continuous education in rural areas, the Academia Danubiana. The life science universities have the duty within their “third mission” to support and organize continuous education to foster the development and livelihood in the Danube region. The innovative approach involves the local stakeholder/communities in the development of customized educational programs. Florina Deleanu focussed also on the strengthening of local communities by re-introducing ornamental vegetable gardening as means of improvements in economy and communication of local communities. Ana Butcaru presented two excellent papers concerning roses for petal production. She established a complete organic cultivation system for roses from soil pre-treatment using different crops to get rid of e.g. nematodes, planting, raising the plants, biological plant protection to harvest and even frost protection. Nutritional-wise, dried petals should be used instead of cooked products. Val Stoian presented results from N-leaching studies following excess mineral nitrogen application under different crops as modified by soil texture. The oral session ended with flowers – a paper presented by Ioana Crişan about Iris germanica and the use of arbuscular mycorrhizal symbioses in different cultivars. In-depth research focussed on water use efficiency – varying considerable between cultivars, making them more or less suitable for dryer regions.
Very well made posters complemented the oral session. The authors presented the posters during the poster viewing session. The contributions covered a variety of additional topics, from fig and peach propagation, mays resistance breeding against fusarium, homemade fungizides, apple storage, challenges of recovering the drainage system in the Moldova River watershed to agrotourism and food products for athletes.
Overall, the session provided a basket of interesting and excellently presented topics showing the diversity of concepts, strategies and challenges to develop the rural area by agricultural activities.

9th CASEE Conference - Session 2

Session 2: Renewable resources – possibilities and constraints (including forests and biotechnology)

Chairs:

Prof. dr Florian Borlea, BUASVMT, Romania
Acad. prof. dr. Doru C. Pamfil, University of Agricultural Sciences and Veterinary Medicine Cluj-Napoca, Romania

The section included presentations (7 oral presentations) and poster sessions from universities from six countries. Renewable resources are very much used as raw materials for a broad range of end products as well as for renewable energy production all over the world, including Central and South-Eastern Europe, in competition with other natural resources or different materials and products. The presentations belonged to very various topics. The main topics of the section 2 were: Renewable energy, Biotechnology and Forestry. The presentations showed how important renewable energy (photovoltaics) constraints can be avoided: the constant electricity supply to the grid and the critical grid loads. The case study of using a battery-type electric energy storage for a decentralized photovoltaic and electric energy storage systems for autonomus buildings in Austria was presented and discussed as visionary prospective for the future when the share for renewable energy will increase and will be a higher demand to balance the demand and supply.

Another important topic was Biotechnology and the screening of microorganisms displaying acetyl xylan esterase activiy was presented as important development in the field. Another presentation was about one of the most abundant natural polymer: hemicellulose – a major component of lignocellulose biomass located between lignin and cellulose fibers and considered the second most abundant natural polymer on earth. Its main constituent is xylan. Four mutant tested strains displaying the highest acetyl xylan esterase activities were identified and the best acetyl xylan esterase activity was detected. The preliminary testing of SRAP primers in four Ranunculaceae species from Romania, was performed in order to provide fundaments for their conservation strategies. Biodiversity is essential for natural pest control and in this respect tests to identify the most efficient/representative SRAP marker combinations of the Ranunculaceae tested species were performed. The results have highly contributed to perform future genetic diversity analyses; in situ and ex-situ conservation perspective.

Forestry is a very challenging domain in Central and Eastern Europe. A comparison between pristine-pure stand and a mixed beech-oak stand using unmanned aerial vehicle was presented. The complex diversity in natural forest was revealed using unmanned aerial vehicle: canopy cover, upper layer tree crowns and canopy gaps in an managed old mixed beech with oak stand and a pristine pure-beech stand in order to compare them. The natural forest had two times more gaps and crowns/ha compared to the managed forest. Percentage Canopy Cover (PCC) represents the proportion of the ground covered by the vertical projection of the tree crowns [Jennings et al, 1999] and the PCC difference between the natural forest compared to the managed forest is 7 %. The managed forest tree shapes are similar to those in natural forest based on mean Gap shape complexity index (GSCI). This should indicate that species richness level is above normal in this forest. The forest management activities is the cause of the regularly distributed patterns of canopy gaps and trees. The oak species are an important forest resource able to provide renewable and sustainable materials, enriching the ecosystems services and fulfilling the social demands in Western Romania. The important role of environmental factors for wood quality was presented. The relation between oak wood value sortiments and local conditions was studied analyzing the results from the wood auctions in 6 forest districts from Western Romania in the period 2003-2017. The volumes of harvested wood (m3)/sortiments and their sale price series in euro/m3 in each site type were presented.

In conlcusion, the use of renewable resources is challenging in the present-day context of climate change and global changes in general. New strategies and innitiatives at global, european or local level are promoting their use but the decision on utilisation renewable resources is taken in general within a technical, economical-finnancial as well as regulatory and cultural framework.

Possibilities are unlimited because:

  • they are „living” resources and can be managed in a sustainable way.
  • they are renewable but also environmentally-friendly,
  • they are based on natural diversity

Constraints are sometimes high because of the competition on use (ex. of wood biomass: energy versus other industries), land-use problems and because of their sensitive relation with biodiversity and environment.

Session 4: Environmental safety and climate change

Chairs:

Dr. Elena Mateescu, General Manager of the National Meteorological Agency, Associate professor of USAMV Bucharest, Romania
Assoc. Prof. dr Michal Lostak, CULS, Czech Republic

The session on environmental safety and climate change was addressed only by 4 presentations. Although the number looks small, the presentations targeted various issues and demonstrated the heterogeneity of approaches and topics in the field of environmental safety and climatic change. Very good demonstration of how board the field is and what might be the interesting research topic was the first presentation of S. Saremesic linking economic approach to ecosystem services with the question of ecological intensification in the case of Serbia. The second presentation of A. Pasca highlighted the use of GIS to calculate various temperature and precipitation maps for assessing land qualities. Again as in the case of the first presentation this topic also proved how broad the issues of ecological change is. F. Raicu in the third presentation targeted the food quality and demonstrated how it is linked to environmental safety. The case of animal food products analysed through Graphite Furnace Atomic Absorption Spectrometry was used to show the links. The fourth presentation was delivered by G. Risnoveanu. It was a presentation informing about CEEPUS network Ecology and Management of Aquatic Ecosystems in Central, East and Southeast Europe. This presentation was valuable because it showed CASEE participants the importance of such network as CASEE. Highly important were the discussions after every presentations. International atmosphere supported the exchange of ideas and suggestions which was a good impetus for the future work in the field.

Session 5: Agricultural engineering (ATAE)

Chairs:

Prof. Kovacev, UNIZG, Croatia
Univ. Prof. Dipl.-Ing. Dr. Andreas Gronauer, BOKU, Austria

The presentations held in the Agricultural Engineering session gave insight in a wide range of topics. On the first day the focus was on soil tillage techniques and also on the automation and digitisation trends in agriculture. Igor Kovacev from University of Zagreb pointed out the possibilities of energy savings by alternative/reduced tillage methods for arable crops cultivation, while Franziska Mairhofer from BOKU University Vienna gave an overview regarding the management of crop residues under reduced soil tillage as an important aspect in erosion mitigation. Raimondo Gallo presented an innovative approach for automating operational monitoring activities in agri-forestry tasks which could enable the entrepreneurs to have automatically updated all the operative information in a dedicated database system and Maximilian Treiber from Technical University of Munich emphasized the importance of digitisation in agricultural logistics to solve problems in organization, transport, work management and documentation. The second day was reserved for presentations from young scientists and PhD candidates from University of Zagreb, Faculty of Agriculture. Zlatko Koronc presented results of testing DI diesel engine performance using different types of diesel fuel, a research started to determine whether the subsidized fuel for agricultural machinery was the same quality/characteristics as a regular fuel for automotive use. Mateja Grubor showed the comparison results of energy properties of two wheat varieties as biomass resource, whether it was used for heat and/or electricity or in the second-generation biofuels production. Finally, Marko Vincekovic presented a research work on the new type of biofertilizers, microcapsules simultaneously loaded with chemical and biological agents to ensure controlled application through timely release of active ingredients. All presented scientific work was on a high level and the presentations was followed by intensive and productive discussion.
