Toward food waste reduction at universities.

Food waste is a serious problem, which undermines the achievement of many sustainable development goals (SDGs), despite their consideration in the agendas of many countries and companies. Notoriously, food waste (FW) causes different kinds of pollution that affect public health and social justice, while contributing to economic losses. This waste phenomenon has causes, drivers, and impacts that require rigorous assessments and effective approaches to mitigate its noxious effects, which are a serious concern for universities. Within these institutions, reducing food waste becomes a circular economy strategy, which is being utilized to assist in promoting sustainable development. However, there is a need for urgent attention to the specific causes of food waste and for consistent actions to reduce it, while boosting awareness in the campus community and triggering a change in students' eating habits. The purpose of this study is to analyze what can be done to reduce the levels of food waste at universities. To achieve this, a review of the theme's state of the art, which is inclusive of an overview of food waste production at universities around the world, is presented. The study employed a qualitative methodology where a comprehensive review of the literature and case studies analyses from selected world regions were considered. The data indicate that a broad variance exists in producing food waste among universities, from 0.12 to 50 kg/capita/day. More factors influence the problem (e.g., gender, age, season, consumer behavior), as well as strategies to solve and prevent it (e.g., composting, recycling, new designs of packages, trayless meals, education), and benefits leading toward food waste reductions from 13 to 50%. Also, four priority actions were identified to reduce food waste at universities, and these consist of planning and awareness, food preparation and storage, services, and direct waste reuse. With appropriate adaptations, these recommended actions should be deployed as means for reducing food waste at universities around the world, while expanding learning and education in sustainability.

Governance in the implementation of the UN sustainable development goals in higher education: global trends.

Governance is a key component for implementing sustainable development (SD) initiatives in university teaching, research, and projects. This line of thinking also applies to implementing the United Nations (UN) sustainable development goals (SDGs). Despite the role of governance in guiding processes related to the SDGs, few studies have examined these relations in an integrative manner in higher education. To bridge this knowledge gap, this study assesses the connections between governance and implementing the SDGs at higher education institutions (HEIs). Specifically, it relies on two main methods. The first is a bibliometric analysis, where the literature on the topic has been analyzed. The second method uses case studies from a sample of universities. The combined dual approach has identified the extent to which governance issues influence how these organizations perceive and handle the SDGs. The study provides valuable recommendations that may assist HEIs in implementing the SDGs with a due emphasis on governance.

Low carbon futures: assessing the status of decarbonisation efforts at universities within a 2050 perspective.

Background: The implementation of sustainability at universities means that they can also play a key role in the transition to a low carbon economy, and in assisting global efforts towards decarbonisation. Yet, not all of them have so far fully engaged in this area. This paper reviews the state of the art on trends in decarbonisation, and outlines the need for decarbonisation efforts at universities. It also reports on a survey aimed at ascertaining the extent to which universities in a sample of 40 countries across the various geographical regions are engaged in carbon reduction efforts, identifying the challenges faced. Results: The study has shown that the literature on the topic has been evolving over time and that increasing a given university's energy supply from renewable energy sources has been the cornerstone of university-based climate action plans. The study also indicates that even though several universities are concerned with their carbon footprint and actively seeking ways to reduce it, there are some institutional obstacles that need to be overcome. Conclusions: A first conclusion which can be drawn is that efforts on decarbonisation are becoming more popular, with a special focus being placed on the use of renewable energy. Also, the study has shown that, from the range of efforts being made towards decarbonisation, many universities are setting up a team with carbon management responsibilities, have Carbon Management Policy Statements, and review them. The paper points towards some measures which may be deployed, so as to allow universities to take better advantage of the many opportunities an engagement in decarbonisation initiatives offers to them.

Environmental Sustainability Impacts of Solid Waste Management Practices in the Global South.

Solid waste management (SWM) is one of the key responsibilities of city administrators and one of the effective proxies for good governance. Effective SWM mitigates adverse health and environmental impacts, conserves resources, and improves the livability of cities. However, unsustainable SWM practices, exacerbated by rapid urbanization and financial and institutional limitations, negatively impact public health and environmental sustainability. This review article assesses the human and environmental health impacts of SWM practices in the Global South cities that are the future of global urbanization. The study employs desktop research methodology based on in-depth analysis of secondary data and literature, including official documents and published articles. It finds that the commonplace SWM practices include mixing household and commercial garbage with hazardous waste during storage and handling. While waste storage is largely in old or poorly managed facilities such as storage containers, the transportation system is often deficient and informal. The disposal methods are predominantly via uncontrolled dumping, open-air incinerators, and landfills. The negative impacts of such practices include air and water pollution, land degradation, emissions of methane and hazardous leachate, and climate change. These impacts impose significant environmental and public health costs on residents with marginalized social groups mostly affected. The paper concludes with recommendations for mitigating the public and environmental health risks associated with the existing SWM practices in the Global South.

Hospital Outdoor Spaces as Respite Areas for Healthcare Staff During the COVID-19 Pandemic.

The COVID-19 pandemic has created considerable implications for healthcare staff around the globe. During the pandemic, the frontline healthcare workers experience intense anxiety, stress, burnout, and psychological breakdown, with severe implications on their mental and physical well-being. In addition to these implications, anxiety and stress can hinder their productivity and ability to perform their duties efficiently. The literature indicates that hospital gardens and contact with nature can help alleviate psychological distress among hospital staff. However, few studies investigated the role of outdoor spaces as areas for respite and work breaks in healthcare facilities during the pandemic. The present opinion paper highlights the challenges of job stress and psychological distress health workers face during the pandemic. This article also underscores the role of hospital outdoor spaces and garden facilities in coping with the challenges. While other measures to reduce stress among hospital staff and ensure their health and safety are important, hospital administrators and relevant government agencies should also emphasize the provision of gardens and open spaces in healthcare facilities. These spaces can act as potential areas for respite for hospital staff to help them cope with the stress and anxiety accumulated through working under crises.

Consumer attitudes and concerns with bioplastics use: An international study.

The world production of plastic exceeded 360 million tonnes in 2020 alone, a considerable amount of which is not properly disposed of. The significant pressures and damages posed by conventional plastic to human and environmental health suggest that alternatives are urgently needed. One of them is "bioplastic", which is defined as bio-based plastic that is (or not) biodegradable. This paper reports on a study on the perceptions of bioplastics among consumers in 42 countries to identify their levels of information and concerns. The results suggest that most respondents have positive expectations regarding the future of bioplastics to replace conventional plastics fully or partially, especially for food containers, kitchenware, and boxes and bags for packaging. They also reported that the low costs and increased availability of bioplastic products on the market are likely to be the main drivers for their wide-scale adoption. However, many participants are unsure whether they would buy bio-based and biodegradable products if they are expensive. Overall, whereas a rather positive attitude to bioplastics has been identified, greater efforts are needed to address the many information needs of consumers towards upscaling the adoption of bioplastics. Relevant policies are therefore needed to encourage investments in the large-scale manufacture and market uptake of bioplastics. The paper reports on an initial study of consumer behavior, in a sample of countries spread across all geographical regions.

Understanding responses to climate-related water scarcity in Africa.

Water scarcity is a global challenge, yet existing responses are failing to cope with current shocks and stressors, including those attributable to climate change. In sub-Saharan Africa, the impacts of water scarcity threaten livelihoods and wellbeing across the continent and are driving a broad range of adaptive responses. This paper describes trends of water scarcity for Africa and outlines climate impacts on key water-related sectors on food systems, cities, livelihoods and wellbeing, conflict and security, economies, and ecosystems. It then uses systematic review methods, including the Global Adaptation Mapping Initiative, to analyse 240 articles and identify adaptation characteristics of planned and autonomous responses to water scarcity across Africa. The most common impact drivers responded to are drought and participation variability. The most frequently identified actors responding to water scarcity include individuals or households (32%), local government (15%) and national government (15%), while the most common types of response are behavioural and cultural (30%), technological and infrastructural (27%), ecosystem-based (25%) and institutional (18%). Most planned responses target low-income communities (31%), women (20%), and indigenous communities (13%), but very few studies target migrants, ethnic minorities or those living with disabilities. There is a lack of coordination of planned adaptation at scale across all relevant sectors and regions, and lack of legal and institutional frameworks for their operation. Most responses to water scarcity are coping and autonomous responses that showed only minor adjustments to business-as-usual water practices, suggesting limited adaptation depth. Maladaptation is associated with one or more dimension of responses in almost 20% of articles. Coordinating institutional responses, carefully planned technologies, planning for projected climate risks including extension of climate services and increased climate change literacy, and integrating indigenous knowledge will help to address identified challenges of water scarcity towards more adaptive responses across Africa.

COVID-19 and Rapid Course Adaptations in Saudi Arabia: An Experiential Learning and Recommendations for Online Education.

The COVID-19 Pandemic has severely impacted educational systems around the globe, necessitating rapid modifications to the educational milieu while safeguarding human health and wellbeing. Following the closure of universities in Saudi Arabia, the instructors of all theory courses were mandated to switch from face-to-face course delivery to remote teaching and learning. This research examines the challenges and impacts of the COVID-19 Pandemic on the mode of teaching and learning and the numerous adaptations in the pedagogical framework of the Landscape Architecture program at Imam Abdulrahman Bin Faisal University, Saudi Arabia. It also explores the opportunities the transition to online education presents to faculty and students moving forward. The data were collected using an online questionnaire survey and focus group discussions. Data analyses consisted of descriptive statistics and thematic content analysis. The research finds that the sudden transition to online teaching and learning disrupted academic activities and had negatively affected the existing teaching and learning framework. Therefore, the research recommends an adaptable and dynamic teaching framework agile enough to cope with sudden disruptions. It concludes with lessons for future teaching and learning frameworks and amendments for upcoming sessions to deal with similar situations.

Public perception and attitudes to disaster risks in a coastal metropolis of Saudi Arabia.

Disaster risk reduction is an increasingly important policy issue, especially in developing countries that suffer most of the global human and economic losses associated with disasters. Indeed, public awareness and attitudes can help in disaster risk reduction and management efforts toward reducing mortality and economic losses. In Saudi Arabia, many cities have been recently experiencing incidences of disasters, such as floods, disease epidemics, and sandstorms. However, studies on public perception of disaster risk in the country are few and nascent. Therefore, based on a questionnaire survey (n = 683), this paper explores public perception and attitudes to disaster risks in Dammam, a coastal metropolis in Saudi Arabia. The findings indicate that although almost two-thirds (64.7%) of the participants are aware of disasters, and 81% are concerned about disaster risks, less than half (47.3%) believe that their settlements could be at risk. While 37% opine that disasters are caused by both natural factors and human activities, about half (54%) indicate that they can personally contribute to reducing disaster risks. Chi-square analysis indicates a significant positive relationship between place of residence and perception of disaster risks (χ2 (6) = 56.18, p < 0.05), and between place of residence and concern about disaster risks (χ2 (12) = 68.47, p < 0.05). The paper recommends raising public awareness and encouraging positive behaviors in reducing disaster risks in the study area and similar environments.

Public acceptability of treated wastewater reuse in Saudi Arabia: Implications for water management policy.

Treated wastewater reuse is increasingly important for sustainable water resource management, especially in water-stressed countries located in the world's arid regions that rely on groundwater and desalination process for meeting their water demands. This study investigates the socio-demographic variables influencing public perceptions of reusing grey and mixed wastewater for non-domestic uses: firefighting, swimming pools, and car washing. Data were collected from 624 households in the Dammam Metropolitan Area, Saudi Arabia using a structured questionnaire and analyzed using descriptive and inferential statistics. The results from logistic regression indicates that the likelihood of a household to accept reusing treated mixed wastewater is influenced by gender with odds ratio (OR) of 2.71-2.18, residential location (OR = 1.32-1.03), age (OR = 1.22-0.18) and educational level (OR = 1.33-0.98), with a tendency for more acceptance of treated grey wastewater than mixed wastewater. These findings showcase the difficulty that the country could face concerning the public acceptance of treated wastewater for non-domestic uses to augment current freshwater sources even among the educated class. This study is significant because sustainably meeting the country's rising water demands requires the stringent implementation of strategic wastewater reuse policy, including bold steps towards wastewater streams segregation, and intensive public awareness campaigns to change negative perceptions on treated sewage effluent. This study concludes that a substantial reduction in the country's reliance on costly desalinated water and fast depleting non-renewable groundwater requires complete reuse and recycling of treated wastewater for wider non-conventional purposes.

Correction to: Renewable energy utilization to promote sustainability in GCC countries: policies, drivers, and barriers.

Renewable energy utilization to promote sustainability in GCC countries: policies, drivers, and barriers.

There is a growing focus on the role of renewable energy (RE) policies such as feed-in tariffs (FITs), renewable portfolio standards (RPSs), subsidies, incentives, and research and development in the global energy policy mix and in promoting environmental sustainability. Although most developed countries have well-formulated RE policies, in developing countries, such policies face many barriers. This study analyzes the policies, drivers, and barriers to RE deployment for fostering environmental sustainability in the Gulf Cooperation Council (GCC) countries. In the GCC region, the need for economic diversification to reduce dependency on single resource, diminishing hydrocarbon reserve, loss of oil export revenue, climate change mitigation pledges, and abundant solar energy resource are the key drivers for diversifying energy sources to include RE. However, the apparent lack of consolidated policy framework for wide-scale RE utilization calls for a well-articulated policy to advance RE development in each member state. Although FIT and RPS approaches could be effective for initial deployment of small-scale RE projects, a competitive tendering and auctioning mechanisms are more suitable for large-scale projects. Whereas, developing effective energy codes could successfully promote RE deployment, the increased share of RE in energy supply would have synergistic impacts on the region. The GHG emissions avoidance expected to be achieved by the GCC countries will vary between 5 and 247 million tons of CO2 equivalent by 2030. The fulfillment of inspirational RE targets for 2030 would contribute in fulfilling climate change mitigation pledges, environmental sustainability, economic growth, and generating new jobs.

Exploring the determinants of open defecation in Nigeria using demographic and health survey data.

There is increasing global attention to the threats of open defecation (OD) to human health and dignity, and the environment. With at least a quarter of Nigerians (25.1%) or 46 million people practicing OD in 2015, Nigeria ranks third in the world in OD prevalence after India and China. This study explores the socio-economic, demographic and geographic factors that influence and determine the practice of OD among Nigerian households. Data was obtained from 2013 Nigeria Demographic and Health Survey and analyzed using descriptive and inferential statistics. The results indicate that about 32% of Nigerian households, 8% in urban areas and 24% in rural areas, practiced OD in 2013. The practice is significantly influenced (p < 0.001) by households' place of residence (χ2 (1) = 2126.2), geo-political region (χ2 (5) = 1962.6) and wealth index (χ2 (4) = 4622.7), as well as by household head's education level (χ2 (3) = 1253.3), ethnicity (χ2 (3) = 1926.2) and gender (t = -7.1992). The article also discusses the implications of the findings for environmental and public health and recommends that facilitating ownership of latrines by households and communities, and behavioral change interventions are necessary towards substantially reducing or eliminating OD in Nigeria.

Household Response to Inadequate Sewerage and Garbage Collection Services in Abuja, Nigeria.

Provision of sanitation and garbage collection services is an important and yet challenging issue in the rapidly growing cities of developing countries, with significant human health and environmental sustainability implications. Although a growing number of studies have investigated the consequences of inadequate delivery of basic urban services in developing countries, few studies have examined how households cope with the problems. Using the Exit, Voice, Loyalty, and Neglect (EVLN) model, this article explores how households respond to inadequate sewerage and garbage collection services in Abuja, Nigeria. Based on a qualitative study, data were gathered from in-depth interviews with sixty households, complemented with personal observation. The findings from grounded analysis indicated that majority (62%) and about half (55%) of the respondents have utilized the informal sector for sewerage services and garbage collection, respectively, to supplement the services provided by the city. While 68% of the respondents reported investing their personal resources to improve the delivery of existing sewerage services, half (53%) have collectively complained to the utility agency and few (22%) have neglected the problems. The paper concludes by discussing the public health and environmental sustainability implications of the findings.
