Special Issue Information

Dear Colleagues,

Safe and secure food is needed for humans to thrive. Ongoing climate change may cause disruptions in cropping systems, animal husbandry, and safe food storage and processing. Abiotic stress factors associated with climate change, including rising atmospheric CO2, temperature, and extreme precipitation events, can all influence crop susceptibility and disease severity. Furthermore, these conditions can promote the emergence of more virulent pests and pathogens. Pathogens cause billions of dollars in crop losses each year and can produce resilient toxins which contaminate food and feed, making them unsafe. These pathogens can continue to accumulate toxins in storage and during food processing. For animal production, contaminated feed can cause immunosuppression, limited weight gain, and reduced animal fitness, leading to greater susceptibility to opportunistic diseases. Finally, increased temperatures, particularly for non-refrigerated foods, will cause faster spoilage and likely lead to more frequent foodborne disease outbreaks. This Special Issue of Climate will highlight emerging agricultural threats, knowledge gaps, and potential control strategies to ensure a safe and secure food supply.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Climate is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

In many regions, water availability influences grape yield fluctuations more than thermal conditions. This study analyzes dryness indices calculated from observed and simulated RCM data to establish statistical relationships with observed yield data, considered an indicator of food safety. Five dryness indices were analyzed: the number of days without rain, the maximum number of consecutive dry days, climatic water balance, dryness index, and vineyard water indicator. These indices were analyzed for three periods: 1986–2005 (recent past), 2016–2035 (near future) and 2081–2100 (distant future). After this analysis, quadratic regression connections were established between the indices and available wine grape yields in the 22 wine regions of Hungary for 2005–2021 without information on grape varieties and for 2017–2021 with data on grape varieties. Linear agro-technological trends were extracted from these wine grape yield series, whereas the residuals exhibited significant quadratic regression in slightly over 50% of the indices and regions, according to the F-test for the 17 year series. For the short series, these proportions are 29 and 27% for the selected seven white and seven red wine grapes. According to the most significant quadratic regressions, combined with the projected dryness indices, we can expect less average yields with higher interannual variability in the future. Full article
