Energy use occupies an important place among the service activities offered to tourists that guide the tourism industry. The realization of basic needs such as heating, cooling, ventilation, lighting and decontamination in these enterprises are among the important factors that directly affect energy use. In order to obtain the energy needed for the sustainability of services at a more affordable cost, renewable energy sources should be put into operation. In this direction, it makes it more advantageous for businesses in the tourism sector to invest by turning to renewable energy sources in order to maintain their activities more economically. In this context, the main purpose of the study carried out in this part of the book is to reveal the latest developments in the field of evaluation of renewable energy sources in tourism enterprises. Bibliometric analysis was carried out by using the Web of Science (WoS) database in the research and with the findings obtained, it was concluded that the field is new and up-to-date and needs to be studied more. When looking at the WoS categories of studies titled renewable energy in tourism enterprises; it was concluded that more energy fuel, green sustainable science technology, science themes were given weight. According to the network analysis, the most cited authors and countries' densities were determined and the intensive expressions in the network keywords in their studies titled renewable energy in tourism enterprises are renewable energy, renewable energy sources, sustainable tourism, sustainability, carbon dioxide (CO₂) emissions, green marketing, blue economy, and energy efficiency.

The years following the 9/11/2001 terrorists attacks saw a marked increase in community and hospital emergency preparedness, from communications across community networks, development of policies and procedures, to attainment and training in the use of biological warfare resources. Regular drills ensured emergency and health care personnel were trained and prepared to address the next large-scale crisis, especially from terrorist and bioterrorist attacks. This chapter looks at some of the more familiar global health issues over the past two decades and the lessons learned from hospital responses to inform hospital management in preparation for future incidents.

This study is a narrative review of the literature related to lessons learned from four major events in the time period from 2002 to 2023 – SARS, MERS, Ebola, and COVID-19.

The initial search yielded 25,913 articles; 57 articles were selected for inclusion in the study.

Comparison of key issues and lessons learned among the four major events described in this article – SARS, MERS, Ebola, and COVID-19 – highlight that several lessons are “relearned” with each event. Other key issues, such as supply shortages, staffing availability, and hospital capacity to simultaneously provide care to noninfectious patients came to the forefront during the COVID-19 pandemic. A primary, ongoing concern for hospitals is how to maintain their preparedness given competing priorities, resources, and staff time. This concern remains post-COVID-19.

The success of waste management depends on public awareness of environmental issues and the ability of the local government to provide facilities. Many countries have serious problems of financial resources and infrastructure for waste management. As there is a lack of awareness of the population on the importance of waste management, municipal governments only adopt remediation actions to manage waste collection service.

In Angola, during the last decade, the government has been committed to the reconstruction and development of the country, creating infrastructure for the provision of essential services and publishing legal tools to respond to environmental issues. In 2012 the government approved the Strategic Plan for the Management of Municipal Solid Waste (PESGRU). The strategic plan was designed for a time horizon until 2025. Due to the economic crisis that hit the country, the implementation of the plan suffered several setbacks and the deadlines established for the different programmes are being compromised.

A study carried out in 2020 on waste management in Angola, with four of the main provinces as a stage, through the analysis of official documents, direct observation and face-to-face interviews with those in charge of waste management, revealed a lack of funding for the implementation of PESGRU and low assistance from the Ministry of the Environment and the central government and showed the unsustainability of the waste management model in light of the principles recommended by international good practices.
