Special Issue Information

Dear Colleagues,

The agroecosystem is the most vulnerable sector to climate change due to its vast size and its sensitivity to meteorological variables, with significant social and economic consequences for human life.

Farmers are facing the impacts of climate change, primarily manifested through shifts in the frequency and severity of extreme meteorological events. These encompass floods, abnormal heat waves, fires, droughts, high temperatures, hailstorms, storm surges, rising sea levels, river-induced floods, saline intrusion into groundwater, altered soil composition, and degradation stemming from flooding. The repercussions on agroecosystems hinge on the intensity and timing of these events and their spatial–temporal combinations. Therefore, many agronomic crop species have to adapt their growth to adverse environmental conditions. Strategies like drought escape and dehydration avoidance lead to drastic morphological, physiological, and biochemical changes in plants attempting to survive water stress. However, these adaptive measures have direct adverse impacts on the quantity and quality of ecosystem services provided by agroecosystems for food security, resulting in diminished crop yield and less desirable edible products.

Therefore, this Special Issue aims to collect research articles, project reports, reviews, and other types of manuscripts that focus on risk analysis of climate change on agriculture and promote agricultural adaptative strategies, including novel biotechnologies and agronomic applications, as well as new policies and tools for their diffusion using a bottom-up (from a single applicative case to analyze methodologies) or top-down approach (from research studies to applicative cases).

Climate change, with rising temperatures, water crises, and an increased frequency of climate disturbances, poses a threat to the ability of agroecosystems to ensure human access to food by affecting both the quantity and quality of crop production. Currently, there is growing knowledge about the fact that agrivoltaic systems may represent a direct strategy to cope with climate change driven by carbon dioxide emissions for energy production, preserving the capacity of agroecosystems to maintain food security. The aim of this work was to investigate the impact of environmental conditions generated by photovoltaic (PV) panels for sustaining open-field tomato (Solanum lycopersicum L.) fruit production under varying water supply regimes. Tomato plants were grown beneath PV panels or in full sunlight. In each scenario, two plots with an equal number of plants were subjected to different irrigation levels: high watering (HW) and low watering (LW). The results showed a lower number of tomato fruit produced grown under the PV panels, with an increased fruit size and water content under a normal water supply. The Brix degrees of the tomato fruits grown under the panel were more comparable to the fruits commercially available on the market than the Brix degree of the fruits grown in open-field sunlight. Thus, our data supported the conclusion that the agrivoltaic system, in the context of climate change with the enduring drought and long-term water scarcity, can be a good adaptation strategy to maintain favorable tomato production compared to the full sunlight conditions. Furthermore, these results can be important for planning breeding programs, since in many cases, the tomato fruits grown in full sunlight were seedless. Full article
