Special Issue Information

Dear Colleagues,

Climate change poses a significant threat to global food system sustainability. Shifts in temperature, humidity, and precipitation and the increasing frequency of extreme weather events are impacting crop yields, agricultural practices, and food nutritional quality. These changes also influence the prevalence and severity of foodborne illnesses by affecting pathogen and pest dynamics. Simultaneously, efforts to mitigate greenhouse gas emissions and adapt to climate change are transforming food production, processing, distribution, consumption, and waste management, all of which contribute to emissions. This Special Issue will explore the complex interplay between climate change and food systems, examining interconnected challenges and opportunities. We invite contributions addressing the technical, environmental, economic, social, and ethical dimensions of this critical nexus. The scope includes, but is not limited to, the following topics:

The impacts of climate change on food production, food safety, and security.

  • Mitigation and adaptation strategies: sustainable agriculture, sustainable processing and packaging, sustainable distribution and transportation, and sustainable consumption and waste management.
  • Economic and policy dimensions: economic costs, national and international policies, international cooperation, trade agreements, and climate finance.
  • Social and ethical considerations: public perceptions and behavioral changes, food security and equity, and social and cultural dimensions of food systems (e.g., traditional knowledge, local systems).

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 250 words) can be sent to the Editorial Office for assessment.

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.

Heat waves have emerged as an escalating climate threat, triggering cascading disruptions across food, energy, and water systems, thereby undermining resilience and sustainability. However, reviews addressing heat wave impacts on the food–energy–water (FEW) nexus remain scarce, resulting in a fragmented understanding of cross-system interactions and limiting the ability to assess cascading risks under extreme heat. This critical issue is examined through bibliometric analysis, scoping review, and policy analysis. A total of 103 publications from 2015 to 2024 were retrieved from Web of Science and Scopus, and 63 policy documents from the United States, the European Union, Japan, China, and India were collected for policy analysis. Bibliometric analysis was conducted to identify the most influential articles, journals, countries, and research themes in this field. The scoping review indicates that agricultural losses are most frequently reported (32), followed by multiple impacts (19) and cross-sectoral disruptions (18). The use of spatial datasets and high-frequency temporal data remains limited, and community-scale studies and cross-regional comparisons are uncommon. Mechanism synthesis reveals key pathways, including direct system-specific stress on food production, water availability, and energy supply; indirect pressures arising from rising demand and constrained supply across interconnected systems; cascading disruptions mediated by infrastructure and system dependencies; and maladaptation risks associated with uncoordinated sectoral responses. Policy analysis reveals that most countries adopt sector-based adaptation approaches with limited across-system integration, and insufficient data and monitoring infrastructures. Overall, this study proposes an integrated analytical framework for understanding heat wave impacts on the FEW nexus, identifies critical research and governance gaps, and provides conceptual and practical guidance for advancing future research and strengthening coordinated adaptation across food, energy, and water sectors.
