Inappropriate food conservation practices along with insufficient and inefficient storage systems are often responsible for the deterioration in quality of agricultural products leading to insecurity economic loss. Open sun drying is a well-known traditional preservation technique but limited use due its low efficiency long times. Solar considered most effective, economical, green sustainable technology available preserve farm produce. In this regard, an attempt has been made study, review...
In terms of fuel resource, hydropower possesses a prominent advantage over any other large power plants which burn fossil fuels to generate electricity. Moreover, due the abundance in resource availability (as domestic source small streams and rivers), (SHP) are showing prominence all world. SHP have led improved access electricity usage under-developed developing nations, thereby contributing sustainable development goals social empowerment. SHP, as technology, is regarded largest density...
About 50% of all hydropower plants (HPPs) worldwide were originally commissioned more than 40 years ago, so that the advanced age fleet is a major concern across continents, and especially in Europe. The modernization HPPs can generate several benefits terms generation, flexibility, safety, operation, may have neutral or even positive implications for environment. In this work, we appraise options existing plants, with exclusion measures expected to increase hydro-morphological pressure on...
Low-carbon energy transitions taking place worldwide are primarily driven by the integration of renewable sources such as wind and solar power. These variable (VRE) require storage options to match demand reliably at different time scales. This article suggests using a gravitational-based method making use decommissioned underground mines reservoirs, vertical shaft electric motor/generators for lifting dumping large volumes sand. The proposed technology, called Underground Gravity Energy...
Soil erosion is both a major driver and consequence of land degradation with significant on-site off-site costs which are critical to understand quantify. One cost soil originates from the sediments delivered aquatic systems (e.g., rivers, lakes, seas), may generate broad array environmental economic impacts. As part EU Observatory (EUSO) working group on erosion, we provide comprehensive assessment existing sediment removal European Union (EU) catchments due water erosion. These...
There is a significant energy transition in progress globally. This mainly driven by the insertion of variable sources energy, such as wind and solar power. To guarantee that supply meets its demand, storage technologies will play an important role integrating these intermittent sources. Daily can be provided batteries. However, there still no technology provide weekly, monthly seasonal services where pumped hydro not viable solution. Herein, we introduce innovative proposal based on...
In recent years, the effects of human activities and climate change on river flow patterns have become a major concern worldwide. This is particularly true in southern Caspian Sea (SCS) region Iran, where increasing water-intensive socio-economic development significantly altered regimes. To better understand these changes, this study employs two nonparametric methods, modified Mann-Kendall method (MK3) Innovative Trend Analysis (ITA), to examine spatial temporal changes hydrometeorological...
Hydropower represents an interesting technology: affordable, renewable, and flexible. However, it must cope with climate changes new energy policies that jeopardize its future. A smooth transition to sustainability requires decision makers assess the future perspectives of hydropower: about revenue related uncertainty. This investigation a multidisciplinary approach as both streamflow mix will evolve. We simulated based on eight scenarios using semi-distributed hydrological model for our...
The stability of agricultural production, critical for global food security, is increasingly threatened by climate variability and extreme weather events. This study focuses on identifying evaluating climate-induced stress thresholds potato yields in Finland the Netherlands, two regions with contrasting climatic agronomic conditions. A comprehensive dataset spanning multiple decades was analyzed using advanced machine learning techniques, including Random Forest modeling, SHAP (SHapley...
Hydrological alterations caused by hydropower dams significantly impact river ecosystems. In Nordic rivers where regulation of for dominates flow alterations, the operations often introduce more frequent fluctuations directly linked to energy demand. cascaded run-of-river plants (ROR-HPPs), upstream affects downstream characteristics, leading complex interactions between and dynamics. Although free-flowing tributaries dampen pulsations due regulation, cascading ROR-HPPs amplify hydrological...
Variations in Arctic snow cover, including Finland, can impact the ecosystem, hydrological cycle, biodiversity, and many other physical processes. Getting a consistent picture of long-term changes relevant cover pattern (SCP), phenology, duration snow-free days, is crucial for understanding regional dynamics water resources. Prevalent SCP assessments excluded critical features such as first last days with maximum which are essential thorough spatiotemporal analysis. To address these gaps,...
Abstract River flow in cold climates is known to be one of the hydrological systems most affected by climate change, playing a central role sustainability downstream socio-ecological systems. Numerous studies on temporal and spatial variations streamflow characteristics have been done, comprehensive study variation hydrologic extremes becoming increasingly important. This evaluated long-running changes magnitude, time, inter-annual variability extremes, including high low 16 major Finnish...
The Caspian Sea and the Hyrcanian forest rely on each other to maintain balanced hydrological climatological conditions preserve local wildlife natural resources. Climate variation impacts this balance ecological status of forest. In study, thermal phenological seasonality in three protected areas is evaluated over a period 33 years (1987–2019). results suggest extensions 3–18 days per decade growing seasons. This could be mitigated by applying policies such as expansion areas, stringent...
Abstract The change in the global energy production mix towards variable renewable sources requires efficient utilization of regulated rivers to optimise hydropower operations meet needs a changing market. However, flexible operation plants causes non-natural, sub-daily fluctuating flows receiving water bodies, often referred as ‘hydropeaking’. Drastic changes flow regimes undermine attempts improve river system health. Environmental decision makers, including permitting authorities and...
Contrary to conventional fossil fuel-based electricity generation technologies, renewable energy centered specifically small hydropower, release a lesser amount of anthropogenic greenhouse gases but are normally more expensive. A major segment the capital investment in current hydropower scenario accounts for equipment and construction process costs. The cost administration generally limited analysis civil constructions, electro-mechanical works, neglecting costs related operating...
The transportation sector is going through a rapid transition to electric vehicles minimize our reliance on fossil fuels and reduce CO2 emissions. This also happening in the cargo transport sector, with deployment of trucks. paper proposes that replacement diesel trucks should first happen routes where delivered from location higher altitude lower altitude. way, regenerative braking system truck can completely recharge truck's battery. investigates scenarios could operate indefinitely...
Climate change has repercussions on the management of water resources. Particularly, changes in precipitation and temperature impact hydropower generation revenue by affecting seasonal electricity prices streamflow. This issue exemplifies climate water-energy-nexus, which raised serious concern. paper investigates with a multidisciplinary approach. A holistic perspective should be favored as is complex, consequently, we chose to investigate specific case study Italy. It allows grasping...
