Food insecurity is an economic and social condition involving limited or uncertain access to food. The problem of food insecurity in communities is influenced by economic conditions, food deserts, and barriers to accessing healthy food. Individuals experiencing food insecurity often endure concurrent problems of financial instability, hunger, and poor mental and physical health. Public and non-profit services in the U.S., such as the federally supported Supplemental Nutrition Assistance Program (SNAP) and community food banks, provide food-related assistance to individuals who are at a high risk of experiencing food insecurity. Unfortunately, many individuals who qualify for these services still experience food insecurity due to barriers preventing them from accessing food. Effective approaches for removing barriers that prevent individuals from accessing food are needed to mitigate the increased risk of chronic disease among vulnerable populations. This study tested a novel food insecurity intervention called FINDING-Food, which stands for Frequent Informational Nudges Directing Individuals to Needed Goods. Informational nudges were used to promote food security through the removal of information barriers to accessing food. The intervention used in this mixed-methods feasibility study consisted of informational nudges in the form of weekly text messages that were sent to food pantry clients experiencing food insecurity (n = 24). The study aims were to test the efficacy and acceptability of the intervention by examining whether the informational nudges could enhance food pantry utilization, increase SNAP registration, and promote food security. Quantitative study results showed a lower prevalence of food insecurity in the intervention group than the control group at the end of the study. Qualitative findings revealed how intervention group participants who completed the study (n = 9) found the text messages to be helpful and informative. These study findings can enhance future food insecurity interventions aiming to eliminate barriers that prevent individuals who are food insecure from accessing healthy food.

The United Nations Office for Disaster Risk Reduction (UNDRR) resolutely endorses the development of people-centred early warning systems. Moreover, several scientific studies have deprecated the vast technology-driven technocratic approaches to implementing these systems, contending the prioritisation of communities and their contextualised needs for systems that ensure effective risk protection and resilience building. However, both the UNDRR and the scientific literature have failed to define appropriate means of implementation (MoI) for community-based early warning system (CBEWS) development. Floods are a major hazard annually impacting several communities in rural sub-Saharan Africa, and though several opportunities for participatory systems have been identified, investment in developing countries is often lagging, and no defined mechanism for developing these systems exists. Adopting a modified Integrated Emergency Management Framework, this study demonstrates that an impact-based CBEWS can be established by leveraging existing resources, institutions and stakeholders, essentially merging last-mile and first-mile approaches. The study further reveals that directly linking technical capacities with community-based efforts allows communities to define system development parameters, strengthen risk knowledge and response, and build resilience for improved physical, economic and environmental protection, essentially bridging the gap between first and last-mile approaches. The study also highlights the need for governments to appropriately streamline DRR to improve coordination and communication.

(1) Background: Human-generated greenhouse gas (GHG) emissions are the largest contributor to climate change worldwide. Climate change negatively impacts human and planetary health, threatening the existence of life on earth. The healthcare industry is responsible for approximately 8.5% of carbon emissions in the United States. Measuring baseline GHG emissions is the first step in emissions reduction. However, very few models of measurement exist for health care organizations. This project aimed to develop and implement a program to measure and track GHG emissions at a midwestern academic medical center (MAMC) and to educate staff on how to manage the process. (2) Methods: A Plan, Do, Study, Act (PDSA) cycle and Quality Improvement methodology were used to develop, implement, and assess a standardized GHG emission inventory process to measure Scope 1 and Scope 2 baseline emissions and provide virtual training and education to the accountable staff. A pre- and post-survey design was used to measure the knowledge and readiness of the staff after the implementation of the GHG inventory training. (3) Results: The GHG inventory process was validated through an external verification process, and the measurement of Scope 1 and Scope 2 baseline GHG emissions was completed and verified for accuracy through a data comparison review. The pre-post-training survey showed an increase in the knowledge and readiness of staff to maintain a GHG inventory. (4) Conclusions: This work shows the feasibility of obtaining baseline GHG emissions data at large medical centers. It represents the initial phase of the overarching goal to develop site-wide and system-wide carbon reduction strategies and a climate action plan within this health system.

This article explores sustainable development from a gastronomic perspective. Humanistic perspectives on food offered by gastronomy are explored as an asset in cultivating self-awareness capacities needed for sustainable transformations of society. The purpose is to explore how gastronomes can cultivate understandings and explanations of sustainability to be conveyed to individuals via meals. In semi-annually recurring dialogic interviews, four university-educated gastronomes cultivated their understandings and explanations of sustainability, and modeled how these could be communicated to other individuals. The dialogues gradually brought the ideas of the researcher and the participants toward a common explanation of the potential ways gastronomic competency could advance sustainable development. The results highlight two ways of understanding gastronomic sustainability: functionally as practical communication, and formally as a cultural issue. Based on H.G. Gadamer’s idea of bildung as hermeneutic interpretation, we argue that self-awareness is a process which is rooted in how knowledge is interpreted, understood, and explained by the individual. Practical participation in culturally influenced meals makes gastronomy a bridge between individual and societal issues, whereby gastronomic competencies can cultivate sustainable commitment, judgment, and community. In this way, gastronomic sustainability represents an approach to sustainable development that, significantly, also involves the cultivation of sustainable meaning.

Food insecurity is an ongoing problem in the U.S. with implications for health problems and social disadvantages. Past food insecurity intervention studies have targeted barriers to accessing healthy food. However, information barriers have not been adequately addressed by food insecurity interventions. This research included the first phase of a two-phase feasibility study that involved testing a text message as an informational nudge through interviews among a small, preliminary sample of adults in the southwest U.S. (n = 10). Interview questions focused on the message content, persuasiveness, relevancy, clarity, and details that participants liked and disliked. A qualitative content analysis of interview responses then highlighted any necessary modifications to the text message. Interview responses highlighted that the message conveyed details about how to access food assistance resources. The message was perceived as informative, clear, and friendly. Participants highlighted the need for better spacing in the message layout, more details about the Supplemental Nutrition Assistance Program (SNAP), and a better explanation for why SNAP is relevant. Text message readability, relevancy, and informativeness were common concerns raised during interviews. Participant-informed modifications to the text message were applied in preparation for using the message in a food insecurity intervention. This research is a novel contribution to the extant literature on nudges, as no known intervention study has used informational nudges to exclusively promote food security. Future food insecurity research efforts should similarly test novel interventions to ensure the intervention is acceptable and relevant for the target population.

Planet.Health addresses imagination and coordination challenges for planetary health through innovative approaches to social organising. This report presents the findings from the inaugural Planet.Health event in 2022, including the Planet.Health unconference. An unconference is a participant-driven event format that provides flexibility for emergent ideas and connections. In this (un)conference report, we share the challenges, achievements, and lessons learned during the initial year of activities in the leadup to and following the Planet.Health unconference event. We also discuss how the intersection of web3 and planetary health—a major focus of the first year—provides an alternative lens for envisioning, innovating, and coordinating beyond conventional social and institutional frameworks. We explore the potential impact of web3 technologies and decentralised social, economic, and financial networks and highlight the implications of these approaches for addressing planetary crises and supporting a flourishing human–environment relationship. As a new contribution to the planetary health field, this work emphasises the importance of building decentralised systems to foster creative actions and inspire global engagement for planetary wellbeing. The report concludes with some practical insights on how we begin to build and sustain decentralised social networks, including a discussion of the benefits and limitations of these approaches.

Illegal disposal of solid waste is a significant issue in many parts of the world, particularly in urban areas. Because of unprecedented urbanization, these areas are crowded, putting pressure on the already inadequate municipal services such as waste management. As municipalities fail to provide adequate and effective waste management services, the expansion and proliferation of informal settlements contribute to the problem of illegal dumping. Apartheid spatial planning produced environmentally unsustainable cities characterized by glaring disparities in municipal resource allocation, disturbingly inefficient transportation systems, and widespread urban insecurity. Therefore, this study examines how the expansion of informal settlement at an unprecedented rate contributes to illegal dumping post-apartheid by conducting a systematic review. Using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines, a literature search from 1994 to 2023 was conducted in the field of waste management. The review focuses on three key aspects: (1) factors that contribute to illegal dumping in townships; (2) waste management laws during apartheid and post apartheid; and (3) waste collection system in townships and spatial planning. South Africa’s inequality is a major contributor to environmental degradation. The situation was exacerbated by efforts to prevent urban migration and forcefully remove black people from cities; apartheid ideology justified the dormitory-like nature of urban townships. In the South African context, the literature reveals that there is a research gap in the application of technologies and effective waste management plans to keep up with the growing number of informal settlements. Furthermore, despite progressive environmental policies, implementation has been ineffective. This study offers valuable evidence on the spatial and temporal dynamics of informal settlements, addressing both the location and time aspects. A robust government-led Community Participation in Solid Waste Management program is required immediately.

In the ongoing series of interviews, Challenges Advisory Board member and Nova Institute for Health Fellow Alan C. Logan meets with thought leaders, scientists, scholars, healthcare professionals, artisans, and visionaries concerned about health at the scales of persons, places, and the planet. Here, Dr Stephen J. Schoenthaler of California State University, Stanislaus, responds to a set of questions posed by Challenges. For over forty years, Dr. Schoenthaler has been at the forefront of the research connecting nutrition to behavior and mental health. In particular, Dr. Schoenthaler’s work has examined relationships between dietary patterns, nutritional support, and behaviors that might otherwise be associated with criminality and aggression. Although the idea that nutrition is a factor in juvenile delinquency was popularized in the 1950s, the area received little scientific attention. In the 1970s, the idea that nutrition could influence behavior gained national attention in the US but was largely dismissed as “fringe”, especially by those connected to the ultra-processed food industries. Today, relationships between diet and behavior are part of the robust field called “nutritional psychiatry”; emerging studies demonstrate clear societal implications, including those within the criminal justice system. Here, Dr. Schoenthaler discusses how we got here and updates Challenges on where the field has moved, with an eye toward future possibilities. Dr. Schoenthaler reflects on the early influences that shaped his interest in the field and discusses the ways in which this research, especially in the context of criminal justice, is related to the many interconnected challenges of our time.
在正在进行的一系列采访中，挑战咨询委员会成员和新星健康研究所研究员Alan C. Logan会见了思想领袖、科学家、学者、医疗保健专业人员、工匠和有远见的人，他们关注人、地方和地球的健康。在这里，斯坦尼斯劳斯加州州立大学的斯蒂芬·j·舍恩塔尔博士回答了《挑战》提出的一系列问题。四十多年来，Schoenthaler博士一直处于将营养与行为和心理健康联系起来的研究的前沿。尤其值得一提的是，舍恩塔勒博士的研究研究了饮食模式、营养支持和行为之间的关系，这些行为可能与犯罪和攻击行为有关。虽然营养是青少年犯罪的一个因素的观点在20世纪50年代很流行，但这一领域很少受到科学的关注。上世纪70年代，营养可能影响行为的观点在美国引起了全国的关注，但在很大程度上被视为“边缘”，尤其是那些与超加工食品行业有关的人。如今，饮食和行为之间的关系已经成为一个名为“营养精神病学”的强大领域的一部分;新兴的研究显示了明确的社会影响，包括刑事司法系统内的影响。在这里，Schoenthaler博士讨论了我们是如何走到今天的，并更新了该领域发展的挑战，并着眼于未来的可能性。Schoenthaler博士反思了早期影响他对该领域的兴趣，并讨论了这项研究，特别是在刑事司法的背景下，与我们这个时代的许多相互关联的挑战相关的方式。

Will a warmer world be a sicker world? What is it about the New England landscape that supports the proliferation of Lyme disease? How are local wildlife trade and global species invasions contributors to emerging diseases such as the 2003 outbreak of monkey pox virus in the midwestern United States? Undergraduate students explore these and related questions in BIOL 1455 Planetary Health: global environmental change and emerging infectious disease—a new online asynchronous course at Brown University. Planetary health is gaining traction in the curricula of institutions of higher learning and online asynchronous courses offer the promise of scaling up to make grand challenges education accessible to many. In our new course, we assessed student learning outcomes (LOs) and sentiment towards the health of humans and the planet using a mixed-methods approach. Students demonstrated competency in each of the LOs after course completion as measured in a pre–post assessment scored with a standardized rubric. Student sentiment was analyzed with an immersion–crystallization qualitative analysis to elucidate themes in responses to the assessments. Many themes on the pre-assessment focused on barriers and problems associated with the health of humans and the planet, while themes on the post-assessment centered on more solutions-based thinking. Collectively, these findings indicate that this online asynchronous course successfully educated students about the myriad challenges facing human and planetary health, broadened knowledge of environmental changes (beyond climate change) that impact health, formalized understanding of now common terms such as “emerging infectious diseases”, and bolstered hope by offering solutions and peer community (even when virtual). Future efforts to integrate planetary health into higher education should focus on broadly accessible and scalable courses, full programs of study (i.e., majors/scholarly concentrations), and extension into institutional programs focused on ensuring equity and wellness for all.

Smith","doi":"10.3390/challe14030036","DOIUrl":"https://doi.org/10.3390/challe14030036","url":null,"abstract":"Will a warmer world be a sicker world? What is it about the New England landscape that supports the proliferation of Lyme disease? How are local wildlife trade and global species invasions contributors to emerging diseases such as the 2003 outbreak of monkey pox virus in the midwestern United States? Undergraduate students explore these and related questions in BIOL 1455 Planetary Health: global environmental change and emerging infectious disease—a new online asynchronous course at Brown University. Planetary health is gaining traction in the curricula of institutions of higher learning and online asynchronous courses offer the promise of scaling up to make grand challenges education accessible to many. In our new course, we assessed student learning outcomes (LOs) and sentiment towards the health of humans and the planet using a mixed-methods approach. Students demonstrated competency in each of the LOs after course completion as measured in a pre–post assessment scored with a standardized rubric. Student sentiment was analyzed with an immersion–crystallization qualitative analysis to elucidate themes in responses to the assessments. Many themes on the pre-assessment focused on barriers and problems associated with the health of humans and the planet, while themes on the post-assessment centered on more solutions-based thinking. Collectively, these findings indicate that this online asynchronous course successfully educated students about the myriad challenges facing human and planetary health, broadened knowledge of environmental changes (beyond climate change) that impact health, formalized understanding of now common terms such as “emerging infectious diseases”, and bolstered hope by offering solutions and peer community (even when virtual). Future efforts to integrate planetary health into higher education should focus on broadly accessible and scalable courses, full programs of study (i.e., majors/scholarly concentrations), and extension into institutional programs focused on ensuring equity and wellness for all.","PeriodicalId":91008,"journal":{"name":"Challenges","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-08-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83016357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
While blockchain and distributed ledger technology offer immense potential for applications in transparency, security, efficiency, censorship resistance, and more, they have been criticized due to the energy-intensive nature of the proof of work consensus algorithm, particularly in the context of Bitcoin mining. We systematically explore the state-of-the-art regarding the relationship between Bitcoin mining and grid decarbonization. We specifically focus on the role of flexible load response through proof of work mining as a potential contributor to renewable energy penetration and net decarbonization of the energy grid. The existing literature has not comprehensively examined this area, leading to conflicting views. We address the gap, analyzing the capabilities and limitations of Bitcoin mining in providing flexible load response services. Our findings show that renewable-based mining could potentially drive a net-decarbonizing effect on energy grids, although key adaptations in mining practices are needed to fully realize this potential. Overall, the paper suggests a re-evaluation of the environmental impact of Bitcoin mining, highlighting its potential role as a facilitator for renewable energy expansion, and decarbonization more broadly.
