The rapid proliferation of digital services and the surge in cloud computing have significantly increased the demand for data centers worldwide. As these facilities consume vast amounts of energy, there is growing concern about their impact on the environment, particularly in relation to climate change. This paper reviews the extent to which data centers contribute to global greenhouse gas emissions and examines the energy efficient strategies being employed to mitigate their environmental footprint. Key findings indicate that without intervention, data centre emissions could rival those of major global industries. Fortunately, innovations in cooling technologies, architectural design, renewable energy sourcing, and hardware efficiency have shown potential in reducing energy consumption. The paper also underscores the importance of a holistic approach that encompasses both technological advancements and policy measures for meaningful progress. In conclusion, while data centers are indeed a source of climate concern, the ongoing advancements in energy-efficient strategies provide a promising pathway towards a sustainable digital future.

Background: This paper presents a comprehensive analysis of the issue of wastewater due to oil spills and pollution in the Niger Delta region of Nigeria, which has led to significant environmental and socioeconomic consequences for local communities. The study employed a secondary data collection approach, drawing on various sources, including published research articles, reports, official records, and satellite imagery.Main body of the Through a systematic review and synthesis of the available literature, the paper identified key challenges, mitigation and remediation strategies, policy recommendations, and areas for future research. The findings of this study revealed that the existing regulatory framework has not been fully effective in preventing and addressing oil spills and pollution in the Niger Delta region due to factors such as weak enforcement, inadequate resources, and overlapping responsibilities among regulatory agencies. Moreover, existing measures for oil spill response, clean-up, compensation, and remediation have had limited success, leaving affected communities to continue suffering from the impacts of oil spills and pollution.Short conclusion: The paper highlights the potential of innovative approaches and technologies, such as advanced oil spill detection and monitoring technologies, bioremediation, and renewable energy, to enhance the effectiveness of mitigation and remediation efforts. Furthermore, the study emphasizes the importance of collaboration and cooperation among various stakeholders, including government agencies, oil companies, local communities, civil society organizations, and international partners, in addressing the challenges posed by oil spills and pollution in the Niger Delta region. Based on the findings, the paper presents several policy recommendations, such as strengthening the regulatory framework, enhancing transparency and accountability, promoting community participation and empowerment, and encouraging investment in sustainable development and clean technologies.

This paper investigates the integration of renewable energy technologies (RETs) in the design of smart buildings with the aim of achieving enhanced energy efficiency and self-sufficiency. As the demand for sustainable building practices grows, it becomes imperative to harness renewable energy sources and leverage advanced control mechanisms. This paper provides a comprehensive overview of the current state-of-the-art RETs, including photovoltaics, wind turbines, solar thermal systems, and energy storage solutions. The focus of the paper extends to the convergence of these technologies with smart building systems, such as energy management systems, building automation, and advanced sensors and controls. Through in-depth case studies, the paper demonstrates how the synergetic integration of RETs in smart buildings can lead to significant reductions in energy consumption, lower carbon footprints, and an enhanced ability for buildings to be energy self-reliant. Furthermore, the paper delves into potential challenges and barriers faced in the adoption of these technologies and offers strategies and recommendations to overcome them. Our findings underscore the transformative potential of merging RETs with smart building designs and emphasize the need for further research and policy support in this domain.

As urbanization and population growth escalate, the challenge of noise pollution intensifies, particularly within the aviation industry. This review examines current insights into noise-induced hearing loss (NIHL) in aviation, highlighting the risks to pilots, cabin crew, aircraft maintenance engineers, and ground staff from continuous exposure to high-level noise. It evaluates existing noise management and hearing conservation strategies, identifying key obstacles and exploring new technological solutions. While progress in developing protective devices and noise control technologies is evident, gaps in their widespread implementation persist. The study underscores the need for an integrated strategy combining regulatory compliance, technological advances, and targeted educational efforts. It advocates for global collaboration and policy development to safeguard the auditory health of aviation workers and proposes a strategic framework to enhance hearing conservation practices within the unique challenges of the aviation sector.

Technological advancement, modern systems of transportation, and an expanding human population have brought in their wake a disturbing situation of exposure to environmental noise. This paper was therefore written to create awareness about the expository effects and impacts of environmental noise pollution on the human population. The target population of interest was the Nigerian population. The key findings were linked and related to existing regulations in Nigeria and other countries to enable effective intervention strategies to reduce the harmful impact of noise pollution. Noise pollution was identified as contributing to the poor health of citizens and as a barrier to development and growth at the national level. By focusing on adverse effects and risk factors, the paper highlighted methods to promote the best interests of the vulnerable population. The paper also acknowledged the issue of industrial and environmental noise pollution from the perspective of its contribution to the economic growth and development of the country. Noise pollution was, therefore, required to be measured and controlled with the help of effective strategic laws. It would help reduce the negative effects on the economy and the vulnerable Nigerian population. This paper will be useful in anticipating future reforms that can reduce the considerable noise pollution and its negative impact on the population group

Introduction: This paper examines the recognition of occupational health and safety (OHS) as a fundamental human right and its implications for Nigerian workers. It highlights the need for employers and governments to prioritize workers’ safety and reviews the challenges faced by Nigerian employers in providing a safe working environment. Methods: A critical review of existing literature and secondary sources of information was conducted to explore the meaning of fundamental human rights as they pertain to OHS. The paper investigated the need for recognizing OHS as a fundamental right and the role of governments and employers in fulfilling this right. Results: The recognition of OHS as a fundamental human right is crucial in protecting workers’ lives and promoting decent work, leading to economic and social benefits. Employers, governments, and international organizations must respect, protect, and fulfill this right for all workers. The adoption of OHS as a fundamental right would encourage governments to introduce legislation promoting a culture of safety and sensitizing businesses to the need to implement policies, procedures, and processes to provide a safe working environment, including standard safety training and adequate resources. Conclusion: Adopting OHS as a human right is beneficial for the workforce but requires investments from employers to comply. The Ministry of Labor and Employment in Nigeria should ensure that all accidents are reported and recorded to build a useful database. Improving OHS in Nigeria necessitates compliance, training, and access to resources. Accurate data is crucial to develop effective solutions for workplace accidents.
