Special Issue Information

Dear Colleagues,

The frequency and intensity of extreme weather events are increasing, which impacts agriculture. In particular, field crop production is a severely exposed sector because farmers must face the potential occurrence of various biotic and abiotic stressors which can cause yield losses and decrease the yield quality. Malnutrition, reduction in the cultivable areas, invasions of pests and diseases, and narrowing biodiversity are severe issues in many parts of the world; therefore, developing and applying complex crop production systems is needed to guarantee the sustainability of agriculture, improving resource use efficiency and reducing the ecological footprint of the sector in parallel with supplying the ever-growing population of the globe with healthy food. Water scarcity is a merging issue worldwide; therefore, improving the water and nutrient use efficiency of cultivated crops could contribute to the preservation of limited resources.

This Special Issue aims to synthesise research focusing on improving the adaptation strategies in agriculture to the negative consequences of climate change or proposing some technologies that can highlight how to utilise the benefits of the changing climatic conditions regionally. This Special Issue aims to distribute the results of basic and applied research and will represent an essential step to offer adaptation strategies to the changing climatic conditions.

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. Agronomy 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 2600 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.

Global warming and climate deterioration are primarily driven by massive greenhouse gas emissions, making the comprehensive assessment of agricultural emissions imperative. This study integrates multiple datasets to achieve three objectives: (1) quantifying agricultural greenhouse gas emissions, (2) identifying regional influencing factors, and (3) exploring mitigation strategies. In this study, a random forest regression model was used to fit the data, providing a new perspective for the analysis of emission factors. Key findings reveal fertilization and irrigation as the dominant emission drivers, with significant regional variations. Specifically, (1) fertilization practices, particularly nitrogen application, exert a greater influence than phosphorus on carbon emissions; (2) irrigation impacts correlate strongly with regional water usage patterns among staple crops; (3) distinct emission patterns emerge across China’s northeast–southwest divide, reflecting variations in grain crop impacts and climatic responses. The study proposes three mitigation approaches: precision fertilization, adaptive irrigation management, and crop structure optimization. These strategies provide actionable pathways for China to meet agricultural emission reduction targets while advancing sustainable development goals. Full article
