“…Broiler housing can be altered to decrease heatwave impacts using misting systems and ventilation (Department for Environment Food and Rural Affairs, 2018). Misting systems are the least expensive method requiring little alteration, but their utility in reducing heat stress is limited since they increase humidity (Khalifa et al, 2018). These issues may be reduced using maximized air flow and/or alternative dehumidification cooling systems to reduce relative humidity levels (Aleem et al, 2022) and overall heat stress impacts.…”

Record-breaking high temperatures were experienced across the United Kingdom during summer 2022. The impacts of these extreme climatic conditions were felt across the food system, including increased energy costs for cold storage, the failure of refrigeration systems in numerous retail facilities, and impacts on livestock including heat stress. Future climate projections indicate an increased likelihood and duration of extreme high temperatures like those experienced in 2022. Learning from the impacts of the 2022 heatwave on the United Kingdom food system can help identify adaptations that build resilience to climate change. We explore the impacts through two case studies (United Kingdom poultry and wheat sectors), discuss potential adaptation options required for a climate-resilient, net-zero United Kingdom food system and consider future research needs. United Kingdom chicken meat production was 9% lower in July 2022 than July 2021; in contrast, energy costs increased for both production and refrigeration. Potential heatwave adaptation measures for poultry include transitioning to heat tolerant chicken breeds, lower stocking density, dehumidification cooling and misting systems, nutritional supplements, and improving retail refrigeration resilience and efficiency. United Kingdom wheat yields were 8% higher in 2022 than the 2017–2021 average. Increases were observed in every United Kingdom region but were least in the South and East where the heatwave intensity was strongest. Future adaptation measures to avoid negative impacts of summer heat stress on winter wheat could include earlier maturing and heat/drought tolerant varieties, earlier autumn sowing, targeted irrigation for drought around anthesis, and soil and water conservation measures.

“…An animal must dissipate the excessive amount of metabolic heat produced into the surrounding environment to control body temperature. This heat regulation can be achieved through different heat losses such as physical, i.e., conduction, convection, radiation, andevaporation (Aarnik et al, 2016 andKhalifa et al, 2018). The rate of exchange depends on the ability of the environment to accept heat and vapor and also on the animal production status (Maya-Soriano, 2012).…”

Many rabbit housing in Egypt were constructed without systematic design models from the viewpoint of sizing evaporative pad cooling system were determined by subtle mathematical models to solve this problem. Four commercial rabbit houses located at 30.95°N and 31.09°E and the pad fan evaporative cooling system were used to reduce the energy and side effects of heat stress on rabbit housing during summer 2017. Three different mathematical forms these forms were ASHRAE form (form 1); airflow depended upon the volume of the house (form 2), and heat balance (from 3). The house that operated with pad fan evaporative cooling and full pad area facing the fan had the best conditions for rabbits and the highest values of cooling performance. Therefore, the actual results for the previous house were the lowest indoor temperature was 26.85°C, the highest indoor relative humidity was 67.83 %, the highest saturation efficiency of cooling was 76.28%, the highest cooling potential was 7.25 °C and the highest value of the temperature-humidity index was 25.6 °C. Finally, when compared the obtained results from these houses with the results from calculation models, can found that these houses related nearly with the heat balance model.

Frontiers is more than just an open access publisher of scholarly articles: it is a pioneering approach to the world of academia, radically improving the way scholarly research is managed. The grand vision of Frontiers is a world where all people have an equal opportunity to seek, share and generate knowledge. Frontiers provides immediate and permanent online open access to all its publications, but this alone is not enough to realize our grand goals. Frontiers journal seriesThe Frontiers journal series is a multi-tier and interdisciplinary set of openaccess, online journals, promising a paradigm shift from the current review, selection and dissemination processes in academic publishing. All Frontiers journals are driven by researchers for researchers; therefore, they constitute a service to the scholarly community. At the same time, the Frontiers journal series operates on a revolutionary invention, the tiered publishing system, initially addressing specific communities of scholars, and gradually climbing up to broader public understanding, thus serving the interests of the lay society, too. Dedication to qualityEach Frontiers article is a landmark of the highest quality, thanks to genuinely collaborative interactions between authors and review editors, who include some of the world's best academicians. Research must be certified by peers before entering a stream of knowledge that may eventually reach the public -and shape society; therefore, Frontiers only applies the most rigorous and unbiased reviews. Frontiers revolutionizes research publishing by freely delivering the most outstanding research, evaluated with no bias from both the academic and social point of view. By applying the most advanced information technologies, Frontiers is catapulting scholarly publishing into a new generation. What are Frontiers Research Topics?Frontiers Research Topics are very popular trademarks of the Frontiers journals series: they are collections of at least ten articles, all centered on a particular subject. With their unique mix of varied contributions from Original Research to Review Articles, Frontiers Research Topics unify the most influential researchers, the latest key findings and historical advances in a hot research area.
