Special Issue Information

Dear Colleagues,

The influences induced by global climate change have been identified as increasing temperature, melting snowpack, extreme rainfall and drought, fire, and sea level rise and can further affect the ecosystem processes and functions that would bring increased pressure to the interdependence between water, energy, and food. Climate change impacts on water resources are often seen as spatiotemporal changes in rainfall, leading to the unreliability of surface water resources and increasing energy usage to extract groundwater resources or produce renewable water. Additionally, water shortages due to recurring droughts can affect energy production, such as hydropower and biofuels. The insufficient supply of water and energy would affect food production and result in food and nutrition insecurity. Due to the trade-offs among water, food, and energy, there is an urgent need to balance the supplies and demands among different strategic sectors, thereby reaching the maximum mutual benefits. The water–energy–food (WEF) nexus, which considers the interactions, synergies, and trade-offs among water, energy, and food, is a cross-sectional approach in natural resource decision-making for managing water resources, food security, and energy sustainability.

This Special Issue collects original research and critical reviews about scientific and technical information on the recent advances in the WEF nexus. The primary areas of interest of this Special Issue include but are not limited to the (1) estimation of climate change impacts on the WEF nexus and related ecosystem processes; (2) development of climate change adaptation strategies by WEF nexus approaches; (3) synergies and trade-offs of the WEF nexus under the climate change impacts; (4) holistic assessment and modeling tools for WEF nexus management; and (5) identification of the optimized life-cycle of water, energy and food elements in the WEF nexus.

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. Environments 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 1800 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.

Benefits of Publishing in a Special Issue

  • Ease of navigation: Grouping papers by topic helps scholars navigate broad scope journals more efficiently.
  • Greater discoverability: Special Issues support the reach and impact of scientific research. Articles in Special Issues are more discoverable and cited more frequently.
  • Expansion of research network: Special Issues facilitate connections among authors, fostering scientific collaborations.
  • External promotion: Articles in Special Issues are often promoted through the journal's social media, increasing their visibility.
  • e-Book format: Special Issues with more than 10 articles can be published as dedicated e-books, ensuring wide and rapid dissemination.

Global remote sensing of solar-induced fluorescence (SIF), a proxy for plant photosynthetic activity, represents a breakthrough in the systematic observation of global-scale gross primary production and other ecosystem functions. Here, we hypothesize that all earth ecosystem variabilities, including SIF, are affected by climate variations. The main contribution of this study is to apply a global empirical orthogonal function (EOF) analysis of SIF to quantify the relations between the large-scale GPP variability and climate variations. We used 2007–2019 SIF data derived from the Global Ozone Monitoring Experiment-2 (GOME-2) satellite sensor observations and a rotated empirical orthogonal function (EOF) analysis to explore global SIF variability over years and decades. The first leading EOF mode captures the well-known ENSO pattern, with most of the variance over continents in the tropical Pacific and Indian Oceans. The second and third leading EOF modes in SIF variability are significantly related to the NAO and PDO climate indices, respectively. Our analysis also shows that the 2011 La Niña (2015 El Niño) elevated (decreased) global SIF. Full article
