description Publicationkeyboard_double_arrow_right Article , Preprint 2025Embargo end date: 01 Jan 2024Publisher:Elsevier BV Cai, Wenyi; Bu, Kunlang; Zha, Lingyan; Zhang, Jingjin; Lai, Dayi; Bao, Hua;Plant factory with artificial light (PFAL) is a promising technology for relieving the food crisis, especially in urban areas or arid regions endowed with abundant resources. However, lighting and HVAC (heating, ventilation, and air conditioning) systems of PFAL have led to much greater energy consumption than open-field and greenhouse farming, limiting the application of PFAL to a wider extent. Recent researches pay much more attention to the optimization of energy consumption in order to develop and promote the PFAL technology with reduced energy usage. This work comprehensively summarizes the current energy-saving methods on lighting, HVAC systems, as well as their coupling methods for a more energy-efficient PFAL. Besides, we offer our perspectives on further energy-saving strategies and exploit the renewable energy resources for PFAL to respond to the urgent need for energy-efficient production.

Wyatt Arnold in OpenAIREAfrican nations are striving to meet increasing energy demands driven by population growth and improving living standards. To reduce emissions, many national capacity expansion plans are attempting to use low-carbon electricity sources and exploit the untapped continental hydropower potential with 300 new hydropower projects planned for a total of around 100 GW of new installed capacity. However, climate, socio-economic, and technological changes are making these investments in new dams more risky and less economically efficient.In this talk, we discuss the role of hydropower projects across different power capacity expansion pathways in Africa. Our multi-scale analysis is built on an integrated modeling framework that combines an Integrated Assessment Model (GCAM), an energy system planning model (OSeMOSYS-TEMBA), a power system model (PowNet), and a strategic river basin-scale reservoir system model. This framework allows the simulation of different future scenarios that harmonize global climate policies, land-use change, climate impacts on water availability, final energy demands, and multipurpose reservoir operations.Our results show that, depending on the scenario considered, between 32 and 60% of the proposed hydropower capacity is not cost-optimal. Moreover, our analysis suggests that hardly any new hydropower will be built after 2030, meaning that its role in terms of installed capacity and generation will gradually decrease in favor of solar and wind power. Besides, floating photovoltaics might also represent a low-impact alternative to hydroelectric dams, producing 20-100% of the electricity from planned hydroelectric dams depending on the scale of deployment of this new technology on existing hydroelectric infrastructure at the African power pool scale. Lastly, we show how policy fragmentation between developed and developing countries in their approach to land use change emissions can have negative side effects on local water demands, producing favorable conditions for the realization of extensive agricultural projects in Africa that increase local irrigation demands and constrain the availability of water resources for hydropower production.These findings show that strategic planning of water-energy systems is essential to navigate the complex landscape of hydropower development in Africa. By adopting a systemic approach, African nations can identify cost-efficient climate-resilient hydropower projects that will contribute in securing a sustainable and resilient energy future.

Global warming may induce significant alterations to the rainfall regimes, especially in the Mediterranean basin, which can be considered as a hot-spot for climate change. Several previous studies focused on the variations in annual rainfall and extreme values, while rainfall seasonal variations were less explored. Rainfall seasonality is a critical climate factor affecting the evolution of natural vegetation, water resource availability, and water security. Rainfall seasonality anomalies may have a high impact, especially in areas of the Mediterranean basin where water supplied during the wet season is used to offset rainfall shortages in the dry season. In southern Italy, the occurrence of long water deficit periods and extremely concentrated rainy seasons could limit water uses and cause serious effects on crop yield and, consequently, on food production.This study aims at exploring potential variations in rainfall seasonality over the last 100 years across three regions of southern Italy (Campania, Sardinia, and Sicily) through a dynamic approach proposed by Feng et al. (2013). The study area is characterized by a Mediterranean climate, where the hydrological year consists of a net alternation of two seasons: a cold-rainy period (wet season), usually including fall-winter months, and a hot-dry period (dry season), typically including spring-summer months. The analysis proposed involves the determination of time-variant values of rainfall magnitude and frequency of the two seasons (wet and dry).Daily rainfall values, recorded between 1916 and 2023, are gathered from hundreds of rain gauge stations distributed over the three regions. A pre-processing procedure was applied for data quality check, data reconstruction in years with less than 80% of missing data, and rain gauge selection; then, only rain gauge datasets with adequate data availability (i.e., more than 70 complete years, with at least 15 years in the last two decades, 15 years in the pre-World War II period, and without significant data interruptions) were retained and used for data analyses. Rainfall depth over each season is idealized as an exponentially distributed independent random variable with mean values h (mm), whereas the seasonal rainfall occurrence is modelled as a Poisson process with rate l (d-1). Rainfall seasonality at each rain gauge was defined annually, considering different indices: the Dimensionless Seasonality Index (DSI); the seasonal rainfall depth and the seasonal values of h and l; the wet season timing (i.e., centroid of the season) and duration. The reference period was divided into different equal-size and non-overlapping subperiods.Differences in the various rainfall seasonality indices and their distributions among the various gauges, regions, and subperiods were analyzed, also investigating the influence of some climatic and topographic factors (i.e., temperature, gauge distance from the sea and elevation). A trend analysis based on Mann-Kendall's and Sen's Slope Method with statistical significance at 95% level of confidence, was also carried out considering a limited subset of gauges with the largest data availability for each region.

During the next few decades, changes in rainfall frequency and magnitude are expected to have major impacts on landscape evolution, social, and economic aspects of human society.We focus on seasonal rainfall variations by the end of the 21st century to define affected landslide-prone areas, future landslide alerts and the impact of shllow and deep-seated landslides on landscape development in the juncture of the Alpine, Pannonian, and Mediterranean region. For this work, we selected the six regional climate models (RCMs) from the EURO-CORDEX project, with the global climate simulations from CMIP5 (Coupled Model Intercomparison Project phase) driven by the six global circulation models (GCMs).  Of the two available spatial resolutions, i.e., 0.11° (12.5 km) and 0.44° (50 km), we considered the 0.11° spatial resolution with a regular 12.5 km grid with spacing between computational points. Six models were selected from 14 combinations of GCMs and RCMs that differ as much as possible from each other while reflecting as closely as possible the measured values of past climate variables. For this study, we considered climate scenarios variable: the daily rainfall datasets of two Representative Concentration Pathways (RCP), namely RCP4.5 (mid-way) and RCP8.5 (worst-case) for the time window from 1981 to 2100. Daily rainfall data were downscaled from 12.5 km resolution to 1 km. The downscaling of the data was performed daily for all six RCMs. To analyse future climate impact on landslides, the calculated models were divided into three 30-year projection periods: 1st period (near-term) between 2011-2040, 2nd period (mid-century) between 2041-2070, 3rd period (end of the century) between 2071-2100. To show the characteristics of seasonal variations, shorter periods within a year were considered, namely four meteorological seasons: winter (December, January, February), spring (March, April, May), summer (June, July, August), and autumn (September, October, November). Future projections represent a 30-year maximum rainfall from the 30-year baseline period in the past (1981-2010).The observed changes in the occurrence of shallow landslides are significant, especially in the winter months, where we can expect more landslide-prone areas compared to the baseline period. Shallow landslides will have a greater impact on the landscape in spring and summer than deep-seated landslides, especially in vineyards.FundingThis work was supported by the by the Slovenian Research and Innovation Agency (the research project J1-3024).
