Dairy production is not only vital for global food security but also significantly contributes to greenhouse gas (GHG) emissions, particularly methane. By focusing on strategies for thermotolerance, methane reduction, and sustainable grazing, we can enhance the resilience of milk cattle and ensure the sustainability of dairy systems in the face of climate challenges. Climate change poses a formidable threat to agricultural productivity, particularly in regions where dairy farming is a cornerstone of rural economies. Uniting four journals and scientific communities, this Collection is a part of the Climate Change and Livestock super Collection which highlights innovative, climate-smart approaches to safeguarding animal health and welfare across aquaculture, porcine, dairy and poultry.

Improving our understanding of thermotolerance in dairy animals can lead to better management practices that enhance animal welfare, productivity, and ultimately, food security. Research into dietary interventions and feed additives has shown promise in reducing methane emissions from enteric fermentation, highlighting the potential for improved feed efficiency and reduced environmental impact. Genetic selection for thermotolerant traits could become more sophisticated, enabling the development of breeds that are better adapted to a changing climate. Additionally, innovative approaches to grazing management, such as agroforestry systems and rotational grazing, could further enhance the sustainability of dairy production while promoting carbon sequestration. In light of these considerations, we invite researchers to contribute to this special Collection by submitting original research articles and reviews. Topics of interest include but are not limited to:

• Strategies for enhancing thermotolerance in dairy cattle
• Innovative practices in grazing management
• Methane reduction techniques in dairy farming
• The impact of climate change on dairy productivity
• Genetic selection for climate resilience in dairy animals
• Sustainable feed practices for reduced GHG emissions
• Economic implications of climate-smart dairy practices
• Policy frameworks supporting sustainable dairy management

This Collection supports and amplifies research related to SDG 13: Climate Action and SDG 15: Life on Land.

All submissions in this Collection undergo the journal’s standard peer review process. Similarly, all manuscripts authored by a Guest Editor(s) will be handled by the Editor-in-Chief. As a newly launched open access publication, this journal has waivers to cover article-processing charges (APCs). For more information about receiving a waiver, please contact alex.waite@springernature.com before submitting a manuscript.
