Special Issue Information

Dear Colleagues,

Frequent extreme weather events are the most visible consequences of climate change and need more attention as agriculture, i.e., food production and the environment, are among the most vulnerable sectors.

The intensification of climate change driven by global warming is threatening the sustainability, food security, and prosperity of many agricultural communities across the world. The higher frequency and intensity of climate variability and extreme climatic events have significantly affected agricultural productivity growth in the last 60 years. Coupled with increasing global population growth and demand for food, increasingly frequent extreme climatic events elicit an urgent and compelling need for the development of new knowledge, technologies and practices enabling scalable, sustainable intensification. Complementarities between adaptation and mitigation options should be considered based on their socio-economic and environmental impacts and their contribution to sustainable development.

The increased variability of driving climatic variables (rainfall, temperature, and atmospheric CO2 concentration) may amplify the effects of climate change influencing crop and livestock production, particularly as extreme events intensify. More frequent droughts, heat waves, and lower soil water availability can markedly reduce farm income while also causing significant natural, human, and social costs through animal mortality, crop failures, loss of vegetation, biodiversity, and soil health with deleterious effects on multiple ecosystem services, staff departures, and labor shortages, and destruction of farm infrastructure. The global scientific community must urgently prioritize new research on systemic adaptation to extreme weather events, understanding the potential in land use and sustainability across space and over time for guiding strategic decisions that can help farming systems adapt to the current climate emergency, anticipate opportunities, avoid disasters, and cope with surprises. Transformational change is ever called for but hitherto somewhat elusive. Transformative change may be realised through bundled operational innovation networks (physical infrastructure, research platforms, economic diversification, socio-cultural and institutional change) that can be together utilised for knowledge exchange and co-creation.

A better understanding of the direct and indirect impact of extreme weather events on food security and on natural, social and economic capital could provide knowledge on how to adapt agri-food systems to such events.

The participatory, collaborative, and interdisciplinary approach considered in this Special Issue encourages the analysis of the impacts of climate change and extreme weather events over multiple land-use options and land-use transitions, generating relevant information to support the debate between stakeholders (researchers, farmers, extension services, funding members, industry, government, and consumers), designing more profitable, resilient, and sustainable farm systems. Regionally relevant works are welcome, as are holistic systems-based adaptation and mitigation assessments, as well as developing alternative regional land-use plans.

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. Land 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 2200 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.

Drought impacts on food security, land degradation and rates of biodiversity loss. Here, we aimed to investigate selenium nanoparticles (Se NPs) influenced plant resilience to drought using the morphological, physiological, and essential oil (EO) quantity and quality of basil (Ocimum basilicum L.) as drought proxies. Treatments included irrigation at 100% field capacity (FC100) as no stress, 80% FC as moderate water stress (FC80) and 60% FC as severe water stress (FC60), together with application of Se NPs at either 0 mg L−1 (control), 50 mg L−1, or 100 mg L−1. The highest (257 g m−2) and lowest (185 g m−2) dry matter yields were achieved in nil-stress and severe-water-stress conditions, respectively. Dry matter yields decreased by 15% and 28% under moderate and severe water stress, respectively. Applying Se NPs enhanced the dry matter yields by 14% and 13% for the 50 and 100 mg L−1 treatments, respectively. The greatest EO content (1.0%) and EO yield (1.9 g m−2) were observed under severe water stress. Applying Se NPs of 50 and 100 mg L−1 enhanced the essential oil content by 33% and 36% and the essential oil yield by 52% and 53%, respectively. We identified 21 constituents in the EO, with primary constituents being methyl chavicol (40%–44%), linalool (38–42%), and 1,8-cineole (5–6%). The greatest methyl chavicol and linalool concentrations were obtained in FC80 with 50 mg L−1 Se NPs. The highest proline (17 µg g−1 fresh weight) and soluble sugar content (6 mg g−1 fresh weight) were obtained under severe water stress (FC60) for the 50 mg L−1 Se NP treatment. Our results demonstrate that low-concentration Se NPs increase plant tolerance and improve the EO quantity and quality of basil under drought stress. Full article
