Special Issue Information

Dear Colleagues,

At present, climate change is becoming more intense and widespread than in the past, mainly due to anthropogenic activities related to the world’s increasing population demands. Global agriculture is extremely exposed to this changing environment and, in addition to cope with this, it is also challenged with feeding up to nine billion people in 2050, according to the Food and Agriculture Organization global trends. Of the 170 crops grown today on a commercially significant scale, only three staple crops supply 40% of our daily calories. Despite the fact that advances in plant genomics, biotechnology and agronomy have increased crop adaptation and productivity within these fluctuating environmental conditions, significant efforts are still required. Indeed, crop yields and food security are presently impacted by several ubiquitous environmental pollutants and, in addition to this, the latitudinal shift of pathogens and pests, which has been demonstrated as a product of climate change, is ultimately exacerbating the process. In addition, despite the fact that current modern agricultural techniques are increasing food production, they are also contributing to climate change, due to the degradations of natural resources and to the release of large amounts of agrochemicals into the environment. It is therefore clear that, to meet next-generation food demands, agriculture will have to adapt to climate change while improving, at the same time, smart and sustainable practices to mitigate it. To achieve these grand challenges, significant advances are required from the plant science research community towards the understanding of the mechanisms and processes that allow crop plants to better respond, in terms of productivity, to this changing environment. In line with the core aims of the 2030 Agenda for Sustainable Development, this Special Issue will focus on the impacts of both biotic and abiotic environmental stresses on crops and model plants, providing new insights about all the different mechanisms and strategies leading to an improvement in the capacity of adaptation to the stress conditions and to the development of climate-smart agriculture.

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. Atmosphere 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 2400 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.

Since maize, peanut, and cotton are economically valuable crops in the southeast United States, their yield amount changes in a future climate are attention-grabbing statistics demanded by associated stakeholders and policymakers. The Crop System Modeling—Decision Support System for Agrotechnology Transfer (CSM-DSSAT) models of maize, peanut, and cotton are, respectively, driven by the North American Regional Climate Change Assessment Program (NARCCAP) Phase II regional climate models to estimate current (1971–2000) and future (2041–2070) crop yield amounts. In particular, the future weather/climate data are based on the Special Report on Emission Scenarios (SRES) A2 emissions scenario. The NARCCAP realizations show on average that there will be large temperature increases (~2.7 °C) and minor rainfall decreases (~−0.10 mm/day) with pattern shifts in the southeast United States. With these future climate projections, the overall future crop yield amounts appear to be reduced under rainfed conditions. A better estimate of future crop yield amounts might be achievable by utilizing the so-called weighted ensemble method. It is proposed that the reduced crop yield amounts in the future could be mitigated by altering the currently adopted local planting dates without any irrigation support. Full article
