As in agriculture uncertainties have increased due to extreme weather events and yield variations, a critical examination of crop rotation strategies is needed. This study analyses the relationship between risk planning, addressing challenges posed by an increasing variability related total contribution margin fluctuations. For systems ‘conventional farming’, ‘organic farming’ ‘farming without pesticides, but with mineral fertilizer’ time series data yields, prices variable costs are collected. The used for Monte Carlo simulation that yields average margins considered crops their (co-)variances, which needed build hypothetical model farm.

This study explores consumer perceptions of the Greek food system, focusing on safety concerns related to pesticide residues. Utilizing a qualitative research design, thematic analysis was conducted data collected from 1024 participants through an online survey platform between May and November 2024. Participants, representing diverse demographics across Greece, provided insights into their experiences regarding safety. The revealed significant themes, including crisis confidence in governance, demands for transparency, skepticism towards system actors. Participants expressed disillusionment with state’s role ensuring highlighted need governance framework that aligns community values. findings underscore importance empowering consumers accurate information foster informed decision-making rebuild trust system.

Biodiversity is declining in many ecosystems, particularly agricultural landscapes. So far, instruments such as the Common Agricultural Policy (CAP) have not been able to halt this trend. Stricter legal regulations tend be poorly received by farmers and leads conflicts. However, their acceptance crucial agriculture a major stakeholder biodiversity conservation.

A key challenge in this century is to ensure safe food for a growing global population while limiting environmental impacts and addressing climate change. Although pesticides high yields, there are downsides their intensive use, including negative effects on the environment, such as water, soil, air contamination, well biodiversity. To promote sustainability transition, innovative farming systems that do not require use of yet non-organic can be part solution. explore attitudes toward pesticide-free, but system, we examined factors drive German consumers accept pesticide-free products, using an online questionnaire survey 1,010 consumers. range hypotheses were evaluated determine influence consumer decisions. Partial least squares structural equation modelling (PLS-SEM) served assess acceptance milk, butter, cheese. The study results show products driven by health consciousness, chemophobia, perceived effectiveness; they inhibited price sensitivity. We find towards positively moderate effect chemophobic effectiveness products. Our findings support researchers, industry professionals, regulatory leaders seeking scalable agricultural production methods.

ABSTRACT In light of the commitment by EU member states to achieve climate neutrality for European continent 2050, expansion renewable energy sources emerges as a significant challenge our time. Agrivoltaic systems, which combine production and food, offer solution alleviate competition limited land resources. However, scientific insights into whether consumers value food produced in agrivoltaic systems are lacking, so far. Knowledge consumers' preferences is, however, crucial successfully commercialize within systems. This study addresses this research gap conducting hypothetical choice experiment with sample 448 German consumers. It examines using raspberries case study. Results random parameter logit (RPL) modeling revealed that willing pay premium labeled information about green electricity. Additionally, on reduced plastic water usage agrivoltaics were also valued, next domestic regional production. A latent class segmentation was carried out targeted marketing resulted four distinct consumer segments differ according their preference structure.
