Saudi Arabia has consistently had low insurance penetration (around 0.89% of GDP over the previous three decades), which is far lower than the worldwide average and the goals set by Vision 2030. This research examines the factors influencing insurance penetration (INSP) in Saudi Arabia from 1990 to 2024, primarily testing the demand-following hypothesis which posits that sustainable economic growth acts as a key determinant of insurance demand. The Kingdom intends to diversify its economy as part of Vision 2030 by lowering its dependence on oil, boosting the use of renewable energy, expanding financial markets, and strengthening resilience. The insurance industry is becoming more and more important for managing risk, making green investments, and allocating long-term capital. The analysis employs annual data and the Autoregressive Distributed Lag (ARDL) bounds testing methodology to investigate both short- and long-term relationships between insurance penetration and five critical variables: sustainable economic growth (SD, indicated by GDP per capita growth), financial development (FD, domestic credit to the private sector as a percentage of GDP), renewable energy consumption (REC, percentage of total final energy consumption), trade openness (TO), and urbanization (URB). The main results show that the insurance industry is very route dependent. In the long term, sustainable economic growth, financial development, and the use of renewable energy all have big beneficial effects on insurance penetration. This shows how important they are for extending the insurable base and supporting green investments. Urbanization has a little negative but statistically weak long-term impact (coefficient −0.0056, p < 0.10), while trade openness does not have any effect at all. In the near term, using renewable energy is the biggest positive driver (coefficient 0.096, p < 0.01). This shows how important insurance is in paying for and reducing the risk of energy transition. These findings are resilient to CUSUM and CUSUMSQ stability assessments. This study makes a unique contribution to the field by presenting the first single-country cointegration analysis of an oil-rich economy undergoing structural transformation, directly correlating the adoption of renewable energy with insurance demand, supported by data extending to 2024. The results show that making insurance markets work with the Saudi Green Initiative through green insurance products, mandated coverage for private finance, and digital/micro-insurance aimed at city dwellers can help Vision 2030 targets be reached faster. Policy suggestions stress the need to combine insurance with changes in the financial and renewable energy sectors in order to reach greater penetration goals (which have recently been raised to 3.6–4.5% levels) and build a more diverse, strong, and low-carbon economy.

The maize weevil is a major postharvest pest of stored maize, causing substantial quantitative and qualitative grain losses and posing a serious threat to food security. In many regions of the world, particularly in developing countries where maize is a staple crop, maize weevil infestations can account for up to 50% of postharvest maize losses annually. Traditionally, synthetic pesticides have been used to manage maize weevils, but their prolonged application has been associated with environmental contamination, pesticide resistance, and adverse health effects in humans and animals. These challenges have inspired the search for safe, eco-friendly, and bioactive alternatives from natural sources. Citrus plants are among the most widely consumed fruits globally, with their peels and leaves constituting a significant proportion of agricultural waste. These waste products are rich in essential oils, particularly limonene, which has demonstrated potent insecticidal properties against maize weevils. Repurposing citrus waste into biopesticides offers a sustainable strategy for mitigating maize weevil infestations, thereby reducing postharvest maize losses and enhancing food safety and security. This review examines the prospects of citrus limonene in the development of safe and effective maize weevil biopesticides, highlighting its major chemical constituents, biological activities, and mechanisms of action.

This research compares the Mediterranean and Japanese diets and considers diet as associated with anti-ageing as well as leading a long and healthy life. Since Mediterranean countries, including Italy and Greece, have one-third the mortality ratio with respect to cardiovascular diseases compared to America and northern Europe, the Mediterranean diet is regarded as healthy. Here, the research shows the reasons why Mediterranean and Japanese diets have these properties. Both the Mediterranean and Japanese diets are typically low in fat, sugar, and calories, and are characterised by a high intake of vegetables, legumes, fish, and cereals. Differences include a greater consumption of polyphenol-rich extra virgin olive oil, dairy products, and a lower amount of meat consumption in the Mediterranean diet, as well as less use of fat; there is an abundant consumption of fermented foods and seaweed in the Japanese diet. Japan’s globally leading long life expectancy is partly attributed to the cultural concept of “ME-BYO,” which emphasises recognising and managing non-disease conditions before they develop into clinical illness. This tendency may be one of the reasons for the long lifespan of Japanese people. Full article

Olive leaves (Olea europaea) are the most abundant agricultural by-product of olive tree cultivation, generating substantial waste each year. Their disposal is deemed an environmental challenge, particularly in Mediterranean countries that dominate the olive oil sector, yet their rich bioactive profile makes them promising candidates for functional food development. This study aimed to determine the total antioxidant capacity (TAC) and total phenolic content (TPC) of olive leaf powder extracts using different extraction solvents and methods to identify the most efficient strategy for possible incorporation into functional food systems. Extractions were performed with distilled water, 70% ethanol, 80% methanol, and 50% acetone using three methods: stirring, soaking, and ultrasound-assisted extraction (UAE). TAC and TPC were quantified using the FRAP and Folin–Ciocalteu assays, respectively. Among solvents, acetone consistently yielded the highest values across most methods (TAC: 19.02 mmol Fe²⁺/L, TPC: 1289.95 mg GA/L), while ethanol also showed strong extraction performance (TAC: 15.35 mmol Fe²⁺/L; TPC: 1214.76 mg GA/L), offering a safer and more scalable option for food applications. Method-wise, UAE achieved the greatest phenolic recovery, while both UAE and stirring proved effective for antioxidant extraction. Overall, these findings provide quantitative evidence supporting possible incorporation of olive leaf powder as a valuable ingredient in functional foods and other sustainable applications, while also contributing to the circular economy through the sustainable valorization of agricultural waste.

This study investigates the contributions of five key sectors—insurance, materials, utilities, real estate, and transport—to the financial markets of six Gulf Cooperation Council (GCC) countries from 2004 to 2023. Grounded in the Sectoral Linkage Theory and Endogenous Growth Theory, the study employs a Panel Autoregressive Distributed Lag (Panel ARDL) model to examine both short-term and long-term sectoral impacts on financial market resilience. The findings reveal that the insurance and transport sectors offer short-term market stimulation, but lack persistent effects. Conversely, the materials, utilities, and real estate sectors exhibit strong, long-run contributions to financial stability and economic diversification. These results highlight the asymmetric impact of sectoral dynamics on market performance in resource-rich contexts. This research contributes to the literature by providing empirical evidence on sectoral interdependence in oil-dependent economies and highlights the importance of structural diversification for sustainable financial resilience. The study provides actionable insights for policymakers and investors seeking to enhance market resilience and reduce reliance on hydrocarbon revenues through targeted sectoral development.

This article presents the value-added production-sharing contract (VAPSC), an extension of traditional production-sharing contracts (PSCs), which encompasses raw materials production, subsequent processing, and the final ‘sharing’ of goods. Developing countries often face challenges in oil and gas exploration, production, and sector development, necessitating new collaborative frameworks between governments, industries, and international companies. The study justifies the economic terms of VAPSC that align with Lebanon’s national regulations, focusing on offshore gas production and the subsequent production and sale of liquefied natural gas (LNG). The research evaluates VAPSC application in Lebanon through a case study involving offshore gas field development, LNG plant construction, and consequent LNG-sharing. Results demonstrate the VAPSC potential to promote petroleum sector development by generating added value for both the state and society, as well as economic efficiency for the contractor. The research contributes to contract theory by introducing VAPSC as a novel framework for integrating hydrocarbon extraction, subsequent processing, and value-added product distribution, offering a replicable model for other resource-rich developing nations. The main findings include the design of a new type of contract—VAPSC—along with an economic-mathematical model for optimizing government-investor partnerships and the definition of key contractual terms.

Seaweed plays an essential role in the survival of marine life, provides habitats and helps in nutrient recycling. It is rich in valuable nutritious compounds such as pigments, proteins, polysaccharides, minerals, vitamins, omega-rich oils, secondary metabolites, fibers and sterols. Pigments like fucoxanthin and astaxanthin and polysaccharides like laminarin, fucoidan, galactan and ulvan possess immune-modulatory and immune-enhancing properties. Moreover, they show antioxidative, antidiabetic, anticancer, anti-inflammatory, antiproliferative, anti-obesity, antimicrobial, anticoagulation and anti-aging properties and can prevent diseases such as Alzheimer’s and Parkinson’s and cardiovascular diseases. Though seaweed is frequently consumed by Eastern Asian countries like China, Japan, and Korea and has gained the attention of Western countries in recent years due to its nutritional properties, its consumption on a global scale is very limited because of a lack of awareness. Thus, to incorporate seaweed into the global diet and to make it familiar as a functional food, issues such as large-scale cultivation, processing, consumer acceptance and the development of seaweed-based food products need to be addressed. This review is intended to give a brief overview of the present status of seaweed, its nutritional value and its bioactive metabolites as functional foods for human health and diseases owing to its immunity-boosting potential. Further, seaweed as a source of sustainable food and its prospects along with its issues are discussed in this review. Full article

Over the past decade, Raman spectroscopy and chemometrics have been extensively utilized in the food industry for the research and development of new products but have failed to establish a strong foothold in quality control and the assessment of food items. To bridge this gap, we introduce a novel application of Raman spectroscopy capable of swiftly identifying free fatty acids (FFAs) in cooking oil and quantifying adulteration. This advanced method was validated using camellia oil, a highly esteemed cooking oil in China and various Asian countries known for its nutritional richness and diverse culinary applications. With its growing popularity among high-end food consumers in Asia, camellia oil has increasingly become a target for adulteration, causing dissatisfaction among both consumers and genuine producers. In this study, we employed Raman spectroscopy to characterize the FFA profiles of cooking oil samples, complemented by principal component analysis (PCA) and partial least squares-discriminant analysis (PLS-DA) for sample categorization and adulteration detection in camellia oil. By segregating camellia oil from other vegetable oils and differentiating genuine from adulterated samples using the partial least squares (PLS) method, we achieved a high determination coefficient (R²) of over 0.98 and a low root mean square error of prediction (RMSEP) of less than 1.45%. These findings offer a robust predictive model for rapid camellia oil adulteration assessment, potentially augmenting traditional qualitative tests and streamlining sampling procedures in the food industry.

The Gulf Cooperation Countries are rich in natural resources such as oil, yet they have serious environmental problems. These countries are also located in regions where there is abundance of sunshine, yet are not capitalizing on the use of solar energy—a clean source of fuel. They heavily rely on fossil fuels that are cheap and readily available in the region, causing serious environmental problems. This research investigates the role of trade, technology, and economic growth in improving environmental sustainability in this region; hence, covering the gap existing in the literature on how this region can address the problem of environmental sustainability. This research uses annual data of the Gulf Cooperation Countries for the period 1990 to 2022 and analyses it with the Methods of Moments Quantile Regression. The major findings presented in the research show the importance of technological innovations in ensuring the eradication of environmental deterioration. Technological innovation is observed to reduce environmental problems by 1.94 to 3.11 magnitude. The results also show that trade openness and natural resources rents fundamentally lower environmental deterioration in the long term by 0.02, and 0.05 to 0.09 magnitudes, respectively. However, the results show that economic growth, globalization, and financial development are harmful to environmental sustainability in this region. These factors tend to raise environmental damage by 0.14 to 0.24, 0.34 to 0.43, and 9.2 to 5.74 units on average, respectively. This research gives key policies towards advancing environmental sustainability through trade openness, natural resources rents, and technological innovation in the Gulf Cooperation Countries.

Biosurfactants are amphiphilic molecules capable of reducing the surface tension of water and forming emulsions between immiscible liquids. These versatile molecules find applications in different industrial sectors, standing out in environmental applications, such as the bioremediation agents of contaminated environments. Bioremediation is an emerging sustainable method of controlling the degradation of waste. The present study carried out a bibliometric analysis, reviewing all research published in the SCOPUS database up to 2023, focused on producing biosurfactants from sunflowers with applications in this sustainable method of waste degradation. Using sunflowers to produce biosurfactants proved an ecological, sustainable, and economical alternative to conventional substrates. The results showed that only the seed husks, the oil derived from the seed, and the sunflower stems were used to produce biosurfactants, emphasizing oil as the most used raw material, probably due to its rich linoleic acid content. The preliminary selection detected only 12 articles that addressed the subject under analysis. According to these studies, the tested biosurfactants showed high potential for application in sustainable environmental bioremediation processes and were able to decontaminate soil, water, and liquid effluents. The bibliometric analysis was performed with the VOSviewer software to evaluate the quality of the publications and, above all, to show a more comprehensive scenario of the subject based on the following bibliometric indicators: the most productive journals, publications by country, the most cited articles, the most recurrent keywords, and most productive institutions. These insights will undoubtedly help scientists to develop new and sustainable practices of waste degradation and contribute to bioremediation research using biosurfactants from sunflowers. By showcasing the environmental benefits and practicality of sunflower-derived biosurfactants, this study contributes to the broader discourse on sustainable bioremediation, fostering innovative and eco-friendly waste management solutions.

Governments and politicians are very concerned about the environmental sustainability of the energy sector, particularly with regard to oil and gas. To assist in achieving global climate objectives, the clean energy transition involves moving away from a fossil-fuel-based economy and toward one that is dominated by clean, renewable energy. This reduces carbon emissions. Here, we consider the moderating effects of natural resources, urbanization, and energy consumption between 1990 and 2022 as we analyze the impact of China’s energy transition and the external balance of goods and services on the country’s environmental quality. We used ARDL econometric techniques and present a thorough empirical investigation. Overall, the findings indicate that the ecological footprint is adversely correlated with energy transition, natural resource use, the external balance of goods and services, and renewable energy usage. Urbanization and the use of non-renewable energy, however, are positively associated with that footprint. The use of renewable energy sources, richness of natural resources, and energy transition all contribute to environmental sustainability. The sustainability of the environment is weakened by urbanization and non-renewable energy usage. It is recommended that policymakers facilitate the acceleration of the energy transition by utilizing renewable energy, promoting policies that create favorable conditions for the widespread adoption of renewables, and balancing the nation’s urban structure in a way that enhances self-sufficient urban development and ensures a sustainable future. Limitations of this study and future directions for research are outlined. Full article

China is a major producer of tropical crops globally, boasting rich varieties and diverse functions. Tropical crops account for two-thirds of the plant species in this country. Many crops and their products, such as oil palm, rubber, banana, sugarcane, cassava, and papaya are well known to people. Most of these products are irreplaceable and possess special functions. They not only supply important raw materials for people’s daily life and for industrial and agricultural production but also contribute to the economic growth in the tropical and subtropical regions of China. However, the modern molecular breeding of these crops is severely hampered by their biological characteristics and genetic complexity. Issues such as polyploidy, heterozygosity, vegetative propagation, long juvenile periods, and large plant sizes result in time consuming, low efficiency, and slow progress in conventional breeding of the major tropical crops. The development of genome-editing technologies has brought a new way in tropical crops breeding. As an emerging gene-editing technology, the CRISPR-Cas9 system has been widely used in plants, adopted for its higher targeting efficiency, versatility, and ease of usage. This approach has been applied in oil palm, rubber, banana, sugarcane, cassava, and papaya. This review summarized the delivery patterns, mutation detection, and application of the CRISPR-Cas9 system in tropical crop breeding, discussed the existing problems, and addressed prospects for future applications in this field, providing references to relevant studies.

The depletion of fossil fuels, economic concerns over the sharp fluctuations in oil prices, and environmental concerns including global warming have renewed interest in alternative green energy solutions in the form of renewable energy technologies. Solar energy is one of the most promising and environmentally friendly forms of renewable energy for power generation. However, energy transition towards renewables has been slow in developing countries, particularly in the oil-rich Arab Gulf countries. To assess the perspective of Omani consumers in terms of solar energy use, barriers, and readiness to use solar energy for sustainable development, this study aims to determine the proportion of the Omani population who use solar energy, the barriers to solar energy consumption in Oman, people’s perceptions towards solar energy barriers, policies aimed at promoting solar energy programs, and the likelihood and willingness to use solar energy in the future. This analysis is based on quantitative data collected through a questionnaire survey distributed in Oman between 20 June 2023 to 12 August 2023. We used 113 samples for analysis using Principal Component Analysis and Krushkal–Wallis H-tests. Our results revealed that 95% of the residents and commercial units surveyed are willing to use solar PV in the future. The main barriers identified include high installation costs, high maintenance costs, and lack of awareness. The potential for growth in solar energy consumption and use depends on the capacity of the government to provide substantial incentives, financial support, improved quality, implement public-private partnership programs, as well as introduce a clear solar energy policy. While evaluating consumers’ awareness and intentions to use solar energy in the future, this study offers practical implications for policymakers to forecast the potential growth, identify effective policy instruments for promoting renewable energy, and determine the readiness of the country for transition to cleaner energy consumption.
