1. Ekonomska ocena škode v drogovnjaku po jelenjadi : magistrsko deloIvan Praznik, 2025, master's thesis Abstract: Jelenjad velja za plemenito žival, ki jo je bilo v preteklosti težko opaziti, danes pa se je prerazmnožila do te mere, da povzroča gospodarsko škodo tako v gozdarskem kot kmetijskem sektorju. Škoda se je pojavila tudi v gozdovih kmetije Kajžer, na kateri predstavlja gozdarstvo 40 % prihodkov. Po prijavi škode na 0,29 hektara drogovnjaka so lovci ocenili 49 % škodo v vrednosti 1.003,29 evrov. Zaradi slednjega je v nalogi na podlagi kalkulacije skupnih stroškov in CBA-analize (Cost Benefit Analysis) izdelan dejanski pregled vpliva škode v drogovnjaku na skupni finančni rezultat gozda na podlagi desetletnih obdobij v njegovi 120 letni življenjski dobi (1976–2095). V magistrski nalogi se primerja finančni rezultat teoretično nepoškodovanega sestoja z dejanskim poškodovanim sestojem. Za namen raziskave se je pripravila metoda ocene škode v drogovnjaku. Do sedaj še ni izdelane konkretne metodologije, po kateri bi lahko ocenjevali škodo v gozdu.
Pregled literature, ki je bila uporabljena v raziskavi, temelji na objavljenih strokovnih člankih ter raziskavah doma ter v tujini in naravnana na temo problematike škode po jelenjadi in njeni prerazmnožitvi ter ukrepih za njeno preprečevanje. Model ocene škode je pripravljen v elektronski preglednici Excel in temelji na dosledni premeri poškodovanih in nepoškodovanih dreves. Po tej metodi je vpisano število dreves po debelinskih stopnjah v model, ki so se mu dodali osnovni podatki iz gozdno-gojitvenega načrta, nakar se je v modelu samodejno izvedel preračun.
V zaključku naloge so predstavljeni predlogi odločevalcem v tej panogi in načrtovalcem, kako ravnati ob prerazmnoženosti z divjadjo. Predlogi izhajajo iz literature, ki je bila uporabljena v ta namen, ter rezultatov raziskave, s katerimi se želi predstaviti škodo na daljše časovno obdobje, s pomočjo SWOT-analize pa nekatere nevarnosti, ki so lahko posledica škode po jelenjadi v gozdu.

2. Ekonomika pridelave krme na območjih z omejenimi dejavniki s poudarkom na strmini : diplomsko deloLuka Žunkovič, 2025, undergraduate thesis Abstract: Pridelava sena na območjih z omejenimi dejavniki, kot sta strmine in visoka nadmorska višina, predstavlja poseben izziv za kmetijstvo. V diplomski nalogi smo se osredotočili na primerjavo pridelave sena na dveh lokacijah: strmine v Halozah in pobočja z manjšimi nakloni na visoki nadmorski višini. Cilj raziskave je bil ugotoviti, kako se razlikujejo agrotehnični ukrepi, količina pridelka in stroški pridelave na teh dveh različnih lokacijah. V teoretičnem delu so predstavljene osnove pridelave sena, s poudarkom na vplivu reliefa in nadmorske višine. Posebna pozornost je namenjena problematiki košnje in spravilu sena na strmih terenih ter uporabi specialne gorske mehanizacije. Zbrani so bili podatki o uporabljeni mehanizaciji, agrotehničnih ukrepih ter o količini pridelanega sena. S pomočjo modelne kalkulacije smo dobili rezultate o lastni ceni sena in podatke, koliko stane pridelava sena na različnih terenih. Na podlagi pridobljenih rezultatov so v zaključnem delu predstavljene konkretne primerjave med obema lokacijama. Analizirane so prednosti in slabosti pridelave na različnih območjih z omejenimi dejavniki.

3. Sustainable development of ethno-villages in Bosnia and Herzegovina : a multi criteria assessmentBoris Prevolšek, Aleksandar Maksimović, Adis Puška, Karmen Pažek, Maja Borlinič Gačnik, Črtomir Rozman, 2020, original scientific article Abstract: This paper explores ethno-villages in Bosnia and Herzegovina as an important element of rural and cultural tourism. The attractiveness of natural and cultural heritage is very important for sustainable rural tourism development. In order to improve the process of decision making to enable the sustainable development of ethno-villages, a multi-criteria assessment model has been developed. The methodology is based on qualitative modeling using a multi-criteria analysis via the DEXi software. The model is based on hierarchical relations consisting of three main criteria that are the basis of sustainable tourism development: economic, social, and environmental criteria. The ultimate goal of the model in this study was to evaluate ethno-villages, namely six ethno-villages in Bosnia and Herzegovina. The results of the study show how ethno-villages contribute to sustainable development.

4. Multicriteria assessment of the quality of waste sorting centers - ǂaǂ case studyKarmen Pažek, Jernej Prišenk, Simon Bukovski, Boris Prevolšek, Črtomir Rozman, 2020, original scientific article Abstract: In this paper, the quality of the municipal waste sorting process in seven waste management centers in Slovenia was assessed using the qualitative multicriteria analysis (MCA) method DEX (Decision EXpert) implemented in DEXi software, which is based on multicriteria decomposition of the problem and utility functions in the form of ʺif-thenʺ decision rules. The study was based on eight types of secondary raw materials. The quality of the secondary raw materials, the regularity of the delivery of secondary raw materials to recycling units based on the sorting efficiency, and the loading weight of the individual baled fractions in the transport of secondary raw materials for recycling were the main parameters used in the model. The final assessment shows good waste management service in centers A and D. Centers B, C, and F were rated ʺaverageʺ. The ʺbadʺ rating was assigned to centers E and G.

5. A system dynamics approach to decision-making tools in farm tourism developmentMaja Borlinič Gačnik, Črtomir Rozman, Andrej Škraba, Boris Prevolšek, 2020, original scientific article Abstract: Background: Besides visiting the main tourist attractions in Slovenia, many tourists want to spend their free time in the countryside as well, but the number of farming establishments in Slovenia diminished distinctly in the last years.
Objectives: This paper aims to develop a system dynamics model, with the goal to analyse dynamics of the diversification of agricultural holdings into farm tourism activities in Slovenia.
Methods/Approach: A system dynamics methodology was chosen to model the diversification in farm tourism. First, we present a basic concept of a system dynamics model with a causal loop diagram. Further, a system dynamics model with different scenarios is presented.
Results: The main feedback loops were identified, and the simulation model was used to analyse different simulation scenarios of the transition of farming establishments into farm tourism facilities.
Conclusions: The model provides the answers to the strategic questions about the dynamics of transfer into tourist farms, using several simulation scenarios. The transition mainly relies on subsidies, promotion of diversification and the growth of rural tourism, which provides a relevant direction for the development of future incentives.

6. Developing a diversification strategy of non-agricultural activities on farms using system dynamics modelling : a case study of SloveniaMaja Borlinič Gačnik, Boris Prevolšek, Karmen Pažek, Črtomir Rozman, Andrej Škraba, 2022, original scientific article Abstract: Purpose: This paper aims to analyse the main variables and causal relationships in the system structure of the diversification of non-agricultural activities on agricultural holdings using system dynamics (SD) modelling. The SD model aims to simulate depictions of the behaviour of the real system while testing the effects of alternative decisions over time.
Design/methodology/approach: An SD methodology was chosen to model diversification in farm tourism.
Findings: A system approach increases the authors’ understanding of the transition of agricultural holdings to farm tourism. The results indicate that the transition to farm tourism depends on the level of tourism development in a certain area. The system is influenced by subsidies allocated by authorities to expand primary agricultural activities. The model describes a situation in which the tourism and agricultural industries have been affected by the COVID-19 pandemic.
Research limitations/implications: The research is limited by the small set of available data due to the limited number of farms in Slovenia. One major problem is the difference in statistical data on the same activity collected from different institutions in Slovenia.
Practical implications: The paper includes implications for understanding the transition process to farm tourism, allowing policymakers to experiment with subsidies and promotion to explore the efficacy and efficiency of proposed policies.
Originality/value: This study provides a structured, systemic view of the diversification of non-agricultural activities on agricultural holdings, where the simulation results are a reliable reflection of the behaviour of the actual system being modelled.

7. An Assessment of socio-economic status of women on family farms: Slovenian case studyJernej Prišenk, Urška Vesenjak, Črtomir Rozman, Jernej Turk, Karmen Pažek, 2024, original scientific article Abstract: The question of gender equality is increasingly being raised today and is present at all
levels of society. The topicality of the issue on farms is particularly evident, due to the particular
inheritance processes on farms, the clear division of labour, and intergenerational cooperation that
characterise the agricultural sector. In this research, a multi-criteria model (DEX-SOCIAL) was
developed to understand the broader aspect of rural sociology and the issue of women’s status on
the farm. The paper discusses the status of women on a farm and assesses their social and economic
situation. The methodology includes an online questionnaire in which women in the Eastern and
Western Cohesion Regions participated, as well as other farm members and owners. Subsequently,
the questions were transformed for the requirements of the assessment model, which assessed the life
prospects of women on farms in both the Eastern and Western Cohesion Regions who were aged both
over and under 40 years (criteria for “young successor”). The results of the study show that there
is a clear difference in the qualitative assessment of women’s socio-economic position in relation
to the East–West cohesion region. The social position of women does not differ according to age
structure. The conclusions of the study also present broader applications of the results in the field of
rural development and rural sociology.

8. An Assessment of food value chains to identify gaps and make recommendations for further development: ǂA ǂ Slovenian case studyJernej Prišenk, Jernej Turk, Karmen Pažek, Črtomir Rozman, Andreja Borec, Nejc Zidar, 2024, original scientific article Abstract: The content of this paper presents the research results of a three-year research project in
which a multi-criteria evaluation model (according to the DEX methodology) was developed for
the evaluation of three different food sectors (represented by a cattle breeding chain, a pig farming
chain, and a milk production chain) with added value in Slovenia. Indicators for the assessment
of the economically, socially, and environmentally sustainable development of food chains were
taken into account. The data for the analysis, such as prices and costs of food, wage levels by sector,
food miles and others, were obtained from various public services between 2020 and 2023. The
final qualitative assessment of the food sectors was uniform (“average”), while the longest analysis
of the results using the plus-minus-1 analysis method showed the reasons for such an assessment
in individual sectors (such as the ratio between the price of agricultural products and the price of
agricultural inputs is poor, the ratio between average gross salary in the individual food sector and
gross salary in the agricultural sector is poor, etc.). In addition to the results already mentioned,
recommendations or suggestions for building a sustainable food chain were made using the results of
the modelling. The research results contributed to a better understanding of the importance of stable
relationships between different groups of indicators and later showed their importance for improving
the functioning of agri-food chains. The results of the research will help various stakeholders (such
as the agricultural advisory service, decision-makers at the level of agricultural policy, researchers
in further analyses, and especially the international professional public interested in various case
studies from EU countries) to further analyse and plan for the organisation of the agricultural sector.

9. The Economic efficiency of micro biogas plants: ǂa ǂSustainable Energy solution in Slovenia - Case studyPeter Vindiš, Karmen Pažek, Jernej Prišenk, Črtomir Rozman, 2024, original scientific article Abstract: This paper presents a simulation model for determining the most suitable type of microbiogas plant for small local communities on Slovenian farms, focusing on the efficient processing of organic waste. This model uses various input parameters, including different types and quantities of slurry and corn silage. Four different scenarios were developed to represent potential plant sizes, each evaluated using key economic indicators: net present value, breakthrough price, and internal rate of return. A scenario sensitivity analysis was conducted to assess the effects of changes in investment costs, fluctuations in energy prices, and the addition of corn silage to the anaerobic digestion process. The results highlight significant differences in economic viability across the scenarios, with some demonstrating positive financial outcomes and shorter payback periods and others indicating potential financial risks and longer recovery times under certain conditions. The analysis suggests that smaller micro biogas plants may struggle to achieve profitability without optimizing input ratios or reducing costs, whereas larger plants show more favorable economic indicators, provided certain conditions are met. Furthermore, the economic efficiency improves when adding maize silage to the fermentor mixture.

10. Uporaba sistema Farm Manager za poslovno odločanje na kmetijahBlaž Tement, 2024, undergraduate thesis Abstract: Program Farm Manager je spletno orodje, ki se osredotoča na optimizacijo kmetijske proizvodnje v Sloveniji in omogoča kmetom boljše načrtovanje, optimizacijo proizvodnih procesov in enostavnejše upravljanje kmetijskih gospodarstev s centralizacijo ključnih podatkov. Cilj naloge je raziskati uporabo programa, identificirati njegove pomanjkljivosti in predlagati možne izboljšave. S SWOT analizo smo preučili prednosti, slabosti, priložnosti in nevarnosti sistema. Program izstopa zaradi tehnične naprednosti, vsestranskosti in podpore kmetijskim svetovalcem. Vključuje podatkovno podprto odločanje, kar povečuje konkurenčnost kmetij. Uvedba programa na srednje veliki poljedelski kmetiji s pridelavo ekološke pire je pokazala, da program omogoča natančno spremljanje finančnih kazalnikov in izboljšanje produktivnosti. Ekološka pridelava pire, ki vključuje predelavo v izdelke, kot so pirina polnozrnata moka, povečuje dodano vrednost pridelka in ciljne skupine kupcev. Raziskava poudarja pomen tehnoloških inovacij za trajnostno kmetijstvo in zmanjšanje negativnega vpliva na okolje. Pričakujemo nadaljnjo rast digitalizacije v kmetijstvu, kar bo kmetom omogočilo izboljšano upravljanje njihovih gospodarstev in prilagajanje sodobnim izzivom. Ugotavljam, da je Farm Manager ključno orodje za digitalizacijo kmetijstva, saj omogoča optimizacijo proizvodnje, centralizacijo podatkov in s tem povečuje konkurenčnost kmetijskih gospodarstev. Predvidevam, da bo program Farm Manager v prihodnosti postal nepogrešljiv del kmetijskega sektorja, saj bo z nadaljnjim razvojem digitalnih tehnologij še bolj učinkovito podpiral kmete pri optimizaciji njihovih proizvodnih procesov in upravljanju virov.
Keywords: Farm Manager, optimizacija kmetijske proizvodnje, digitalizacija kmetijstva, centralizacija podatkov, konkurenčnost kmetij.
