More than a decade since the outbreak of the revolution in 2011, Libya remains mired in a political crisis and institutionally fragmented, having been the scene of two civil wars. This paper looks at the interrelationship between the national and international dimensions of the conflict to illustrate how the various rival political elites project an image of the country to the outside world (branding) in order to boost their national and international legitimacy, obtain material support and strengthen their bargaining position in the peace processes. To that end, it studies the discourses of the Libyan political elites in three periods: the first Libyan civil war (2011) and the transition phase, the second civil war (2014-2020) and the failed attempt to hold presidential elections in 2021.

Generating electricity from renewable energy instead of fossil fuels brings great benefits to the environment and sustainable development. Thus, assessing the potential of wind and solar energy in agricultural coastal areas can identify sustainable energy solutions for meeting energy demand and producing fresh water for agricultural applications and domestic use. However, it is difficult to accurately assess the wind and solar energy potential in Libya due to the civil war, lack of measured data, and its limited availability. Consequently, this concise work is unique because it is the first to use daily measurement data from Az-Zāwiyah, Libya, for evaluating wind and solar energy based on one year of measured data for 2022. Moreover, the present study aims to investigate the potential of wind and solar energy as promising renewable sources for meeting energy demand in coastal agricultural regions in Libya using multiple datasets for the first time. In this paper, five satellite products (TerraClimate, ERA5, ERA5-Land, MERRA-2, and CFSR) were assessed and compared against measured data for January 2022–December 2022 to understand their suitability, accuracy, and reliability. The results showed that CFSR and ERA5-Land demonstrate the most favorable performance for assessing the wind resource, while all satellite products can be utilized for preliminary solar resource assessment. Then, the assessment of wind and solar resources was evaluated in five agricultural coastal regions (Aljmail, Az-Zāwiyah, Castelverde, Msallatah, and Sabratah) based on the best satellite product for the period of 2000–2022. Furthermore, the performance of the wind and solar power systems was investigated for typical farms, which were chosen to estimate the required energy demand according to daily electrical consumption. The results show that the positive outcomes of implementing these systems were highlighted, with an emphasis on their potential benefits to the entire Libyan agricultural sector. Accordingly, scaling up and generalizing the proposed systems and generalizing them to include all farms in Libya could have a significant impact on national electricity generation, mitigate greenhouse gases, and contribute to the development of the agricultural sector and the country's economy.

The study area is the city of Zintan, in northwestern Libya, which has grown over the past 30 years. Its current population is roughly 30,000. Although the city is in part commercial, most of the population engages in agriculture and primarily grows cereal crops (wheat and barley). The demand of the growing city for agricultural products has increased, intensifying the use of fertilizers, pesticides, and insecticides. Consequently, concentrations of potentially toxic elements (PTE) in the soil have increased. To assess the soil quality (to provide a snapshot of the condition of the soil), systematic sampling was undertaken across a grid of about 2 km × 2 km. The main objective was to determine the chemical and mineral composition of the area of interest, keeping in mind the geological footprint of the terrain. The geologic framework itself is not conducive to elevated concentrations of elements like U, Th, Mo, As, Hg, Pb, and Cr. Therefore, metal concentrations greater than the amounts in the Earth's crust are most likely of anthropogenic origin. A total of 143 samples were collected and chemical analyses were performed using a Thermo Fisher Scientific Niton XL3t GOLDD+ XRF analyzer for the following elements: Mo, Zr, Sr, U, Rb, Th, Pb, Au, Se, As, Hg, Zn, W, Cu, Ni, Co, Fe, Mn, Cr, V, Ti, Sc, Ca, K, S, Ba, Cs, Te, Sb, Sn, Cd, Pd, and Ag. This paper provides examples of elevated concentrations, potentially harmful to the environment, such as those of the following: sulfur of unknown origin (two to three times higher than the Earth's crust average); arsenic, given that there are no related natural phenomena (all the samples measured displayed concentrations higher than those found in the Earth's crust); mercury (concentrations much higher than permissible levels); cesium (additional investigations required to determine the origin); molybdenum; and uranium likely resulting from the use of superphosphates (concentrations nearly always significantly higher than those in the Earth's crust).

The short- and long-term volatility of oil and gas prices has a wide-ranging impact on both parties of petroleum contractual agreements, thus affecting the profitability of the project at any stage. Therefore, the government (first party) and the international oil company (second party) set the parameters of their contracts in a way that reduces the uncertainty. The effect of price fluctuations on economic indicators is investigated in this paper. The Taguchi method is used for the first time to find the best-agreement parameters, which are the "A" and "B" factors, in the standard Libyan agreement. There are four "A" components from "A1" to "A4", and four "B" components from "B1" to "B4". The purpose is to reduce the variability in the response variables, which are the company take (the percent of net cash flow for the international company) and average value of the second-party percent share of production (ASPS). The noise factors considered in this paper are oil, liquefied hydrocarbon byproduct (LHP), and gas prices. The method was applied to a case study of oil field development in Libya. The results showed that "A3" and "A4" were the most important control factors that affect the ASPS, while "B2" and "B3" are the most important factors affecting the company take. To obtain robust results, the most important factors to reduce variability were also determined. The effect of control parameters on the average NPV may be worth more than USD 22 MM in the 1-billion-barrel oilfield case study. The results showed that, for a given combination of "A" and "B" factors with a certain company take, the mean absolute deviation (MAD) of the NPV of the second party was reduced by 18% if the optimal combinations of the levels were used.

This paper takes a cursory and insightful examination of the socio-economic implications of the illegal migration to and from Libya. It aims to provide an interrogation of the underlying causes and exacerbation of the development, its transformation to new forms of slavery and source of income for certain criminal elements, the role of the EU, and how it affects Nigerians and other sub-Saharan African citizens. The paper recommends that the European Union, Nigeria’s federal government, and other sub-Saharan African leadership should endeavor to man their borders very strategically and engage with the Libyan authorities effectively to reduce the illegal migration. Finally, the work recommends that the United Nations Commission for Refugees, International Organization on Migration, North Atlantic Treaty Organization, and importantly, more stable governments of the Middle East, especially Turkey and Egypt should intervene in the process to curtail further conflicts in Libya.

Introduction: There has been a global increase in the prevalence of common mental disorders (CMD), particularly in conflict hotspots. The limited amount of resources is one of the key barriers to effective treatment within Low- and Middle-income countries (LAMICs). The lack of service provision for mental health disorders in LAMICs has resulted in limited opportunities to conduct mental health research. Libya is a North African country that has suffered from ongoing conflict with the current political unrest in Libya further impacting the mental health of the population. Main text: The aim of this review is to conduct a synthesis of evidence regarding the estimated prevalence and associated risk factors of CMD in Libya. A search was completed in the academic databases; PubMed, Medline, EMBASE, PsychINFO, CINHAL, and the Institute for Development, Research, Advocacy and Applied Care (IDRAAC) from inception to March 2020. Only studies that investigated prevalence and associated risk factors of CMD in Libya were included. A total of 219 studies were identified of which 15 met the inclusion criteria for the review. There were (n = 3) papers investigated the prevalence of depression, (n = 4) studies were focused on stress-related disorders and the remaining papers looked at both anxiety and depression. Statistically, sample sizes of the included studies ranged from (n = 41–13,031) for the prevalence studies (mean = 1188.6, median = 233). Conclusion: The status of Libya as a conflict hotspot has led to a reduced level of epidemiological data on mental health, with a vital need to conduct research in CMD. Libya requires better clinical governance which can allow for more scientific research into CMD and enabling the Libyan government to develop evidence-based policy initiatives for CMD.

This research aims to promote the sustainable utilization of locally available, environmentally friendly resources, making a substantial contribution to both mitigating global warming and fulfilling future energy needs. Hybrid renewable energy systems have demonstrated superior stability and reliability compared to single-source systems, all while operating at minimal costs. This paper provides an overview of various hybrid renewable energy systems employed for electricity generation. It underscores that in hot regions, despite high solar radiation, solar PV systems experience reduced electrical yield due to elevated solar cell temperatures beyond the recommended range, especially in summer. In such areas, leveraging solar thermal applications and abundant biomass energy from extensive agricultural activities is preferable. What sets this study apart is its innovative approach: replacing conventional hybrid systems, like PV, wind, diesel generators, and batteries, with a Stirling engine powered by dish solar concentrators, which offer high efficiency and cost-effectiveness. The proposed Hybrid Renewable Energy System (HRES), consisting of a parabolic dish solar concentrator and Biomass Digester (PDSC/BG), transforms challenges into opportunities. It provides the community with a sustainable source of electricity, heating, and cooking gas, simultaneously addressing the region's waste management issues. The system is evaluated at Brack City, Libya, and comprises a 36,560 m3 biomass digester that produces 27 Mm3 annually, a 1230 kW Stirling generator, and a 6006 m2 PDSC collector area. The system will add 5,670,534 kWh of energy to the grid yearly, with a peak load capacity of 1230 kWh and a coverage of 5,892,666 kWh. The system's technical and economical viability is evaluated using SAM software. The project has a 20.04-year payback period, an estimated capital cost of $12,365,896, and an LCOE of $0.075/kWh. Annual CO 2 emissions will be reduced by 7.8 kton as a result of the project. • Introduce a novel off-grid hybrid system design. • Substitute storage with a more reliable, cost-effective biomass gasification source. • Utilize a single Stirling engine for both technologies to reduce capital investment and lower LCOE. • Evaluate the energy, economic, and environmental effects of the proposed system. • Assess biomass impact on different sizes of hybrid renewable energy systems (HRES).
