“…Energy in Libya is currently mainly produced from fossil fuels, which has negative consequences such as depletion of reserves and harmful emissions into the environment such as greenhouse gases and dioxins (Jeffry et al, 2021;Vambol et al, 2016). In addition, deposition of nitrogen and heavy metals has been observed (Li et al, 2021;Bebber, 2021), which requires appropriate measures (Lahori et al, 2023;Yuan et al, 2023;Ziarati et al, 2020;Zahorodniuk et al, 2019). The weakened ecological situation and poor quality of water and air contribute to the rapid development of diseases and epidemics (El Morabet et al, 2023;Grinzovskyy et al, 2017).…”

A radical transformation is occurring in the global energy system, with solar PV and wind energy contributing to three-quarters of new electricity generation capacity due to their affordability. This shift towards renewable electrification of energy services, such as transportation, heating, and industry, will gradually replace fossil fuels in the coming decades. This paper highlights Libya's potential to achieve energy self-sufficiency in the twenty-first century. In addition to its fossil energy resources, Libya possesses favourable conditions for solar, wind, and moderate hydroelectric energy. The solar energy potential alone is approximately 100 times greater than what is needed to support a fully solar-powered system that provides energy consumption similar to developed countries for all Libyan citizens, without relying on fossil fuels. Moreover, Libya's Green Mountain range offers substantial opportunities for low-cost pumped off-river hydropower storage. Therefore, the integration of solar and wind energy, complemented by hydropower and battery storage, is likely to be the primary pathway for the rapid growth of Libya's renewable electricity sector.

“…Due to the accelerated processes of industrialization, the environment is experiencing serious stress, which in turn is reflected in the form of cataclysms and disasters with significant human and financial losses (Dolchinkov, 2024). The extensive use of fossil fuels contributes to global warming (Al-Yasiri et al, 2022) and the release of toxic metals into the environment, resulting in climate change in some regions, decreased yields and the use of chemical fertilizers and plant protection products, which is harmful to public health (Grinzovskyy et al, 2017;Zahorodniuk et al, 2019;Hulai et al, 2022). This chain of events forces us to use green technologies (Omoyajowo et al, 2024) and to search for alternative energy sources (Al-Yasiri et al, 2022; Ahmad and Samara, 2023; Khan et al, 2022).…”

The extensive use of fossil fuels contributes to global warming and the release of toxic metals into the environment, resulting in climate change in some regions. It has been estimated that cooling buildings accounts for about 20% of global electricity consumption and this figure continues to grow. The purpose of the current study is to evaluate the feasibility of using an air conditioning unit for cooling a residential building, powered by solar energy in the conditions of Iraqi Kurdistan. Such an assessment is required for the sustainable development of the region. The study location is Erbil city in Iraq (latitude: 36.1911 °N, longitude: 44.00917 °E). The PVsyst software tool was used for modeling because it is characterized by great versatility in the field of modeling solar energy systems. The specified solar panel power (kW) was a constant parameter. Variable parameters were height of solar panels, albedo reflector, tracker system. In the current study, three simulations were performed in which the variable parameter was height and four simulations in which the variable parameter was the solar panel› angle. An average of 3.5 kWh was produced throughout the day, and an average of 3.3 kWh was produced during working hours. Only 0.2 kWh was produced outside of working hours, meaning that almost all of the electricity produced is available during working hours. This is useful in countries without high feed-in tariffs where only a small feed into the grid is needed. Also with the lowest calculated values (of all the options under study) the energy produced is 2264 kW/h/year or 2.264 MW/h/year (month -January, panel installation height -0.5 m, inclination -20°, azimuth -0°), greenhouse gas emissions of at least 604.3 kg CO 2 per year are eliminated. At the same time, an additional measure to increase the efficiency of using a solar panel to power an air conditioner is to place reflective material in which the reflection rate or reflection coefficient is different under the solar panels. However, as mentioned earlier, this is an expensive solution. In the future, it will be beneficial to develop smart control technologies to improve performance and evaluate the impact of a solar air conditioning.

“…Land degradation (LD) is a global problem in the 21st century because of its negative impacts on biological productivity, the environment, food security, and quality of life. Technogenic processes become more complex every year and worsen the ecological state of the soil due to the settling of toxic dust floating in the atmosphere (Ziarati et al, 2020;Vambol et al, 2019;Hussain et al, 2022a), pollution through waste (Hanoshenko et al, 2022;Hussain et al, 2022b;Vambol et al, 2023), application of plant protection chemicals (Vambol et al, 2020), watering from polluted sources (Khan et al, 2022;Zahorodniuk et al, 2019). The deterioration of soil purity leads to the production of low-quality products that are harmful to human health and activity (Karlova et al, 2017;Hulai et al, 2022).…”

The issue of the land degradation vulnerability index (LDVI) is multifaceted, encompassing climate, soil, vegetation, policy formulation, and human actions. In Vietnam, the convergence of climatic fluctuations and human impact results in phenomena, such as soil sealing, erosion, salinization, and landscape fragmentation. These phenomena are recognized as significant triggers of land degradation. This paper seeks to present a method for assessing a land's susceptibility to degradation by utilizing ten ecological 10 criteria: NDVI; slope; bulk density (cg/cm3); cation exchange capacity in the soil (CEC; mmol(c)/kg); Soil organic carbon stock (SOC; dg/kg), pH; Nitrogen (N; cg/kg); soil thickness (cm); soil surface temperature LST (0C); precipitation of the driest quarter (mm). The research results show that Song Hinh and Son Hoa communes are standing on the most land degradation vulnerability. Some criteria that are considered important in assessing land degradation by the analytic hierarchy process (AHP) technique are NDVI, followed by slope, nitrogen, bulk density, and soil thickness. The results of the study are consistent with records in localities that are often under pressure from drought. Extreme LDVI areas were larger identified on low mountains, slope terrain, and precipitation of driest quarter under 200mm, expanding on the agricultural areas with 40km2 total province agriculture area, followed by grassland (20.3 km2), natural forests (17.2 km2), plantation forests (8.2 km2), residences (8.2 km2), and bare land (8.15 km2). Poor land management practices, such as improper construction, inadequate water management, and lack of terracing, can contribute to soil erosion and land degradation. This LDVI assessment process can be applied to some tropical countries. The NDVI index combined with the slope, nitrogen, bulk density, and soil thickness can be exploratory indicators of land sensitivity to land degradation.
