18 pages, This study investigated the factors influencing consumers' switching intentions to biodegradable plastic products. Applying a modified Motivation-Opportunity-Ability (MOA) framework, we analyzed the impact of factors such as environmental concern, novelty seeking, negative attitude, perceived consumer effectiveness, green consumer availability, and environmental knowledge on switching intention, while also examining the moderating effect of perceived greenwashing. Results showed that environmental concern, perceived consumer effectiveness, and negative attitude from the motivation dimension, and environmental knowledge from the ability dimension, had significant effects on switching intentions. Furthermore, it was found that the level of perceived greenwashing moderated the effects of environmental concern, perceived consumer effectiveness, and environmental knowledge on switching intentions. This study is significant for its focus on consumer perceptions and behavioral intentions towards biodegradable plastics as eco-friendly products, although there is room for debate about its actual environmental effectiveness. Based on the findings, we present practical implications that include the importance of consumer education, the need for companies to provide transparent information, and policy considerations to strengthen consumer sovereignty.
15 pages, This study leverages group-based control theory to explore how fresh starts reinvigorate consumers with low motivation to engage in collective environmental efforts. Typically, individuals with low control over their circumstances show less inclination toward collective goals. However, fresh starts can enhance the influence of perceived control on collective environmental engagement, with global identity mediating this relationship. This hypothesis was supported by two empirical studies. The first study analyzed data from 10,430 corporate participants in an energy-saving initiative, revealing that smaller organizations, which likely experience lower levels of control, made substantial energy-saving efforts early in the year, although this effect diminished over time. The second study of 108 college students found that a fresh start mindset and desire for control, mediated by global identity, enhance environmentally responsible behaviors. These findings suggest that fresh starts can effectively connect control perceptions with proactive environmental actions, underscoring their potential to foster collective environmental efforts.
42 pages, The 2006 United Nations report “Livestock’s Long Shadow” provided the first global estimate of the livestock sector’s contribution to anthropogenic climate change and warned of dire environmental consequences if business as usual continued. In the subsequent 17 years, numerous studies have attributed significant climate change impacts to livestock. In the USA, one of the largest consumers and producers of meat and dairy products, livestock greenhouse gas emissions remain effectively unregulated. What might explain this? Similar to fossil fuel companies, US animal agriculture companies responded to evidence that their products cause climate change by minimizing their role in the climate crisis and shaping policymaking in their favor. Here, we show that the industry has done so with the help of university experts. The beef industry awarded funding to Dr. Frank Mitloehner from the University of California, Davis, to assess “Livestock’s Long Shadow,” and his work was used to claim that cows should not be blamed for climate change. The animal agriculture industry is now involved in multiple multi-million-dollar efforts with universities to obstruct unfavorable policies as well as influence climate change policy and discourse. Here, we traced how these efforts have downplayed the livestock sector’s contributions to the climate crisis, minimized the need for emission regulations and other policies aimed at internalizing the costs of the industry’s emissions, and promoted industry-led climate “solutions” that maintain production. We studied this phenomenon by examining the origins, funding sources, activities, and political significance of two prominent academic centers, the CLEAR Center at UC Davis, established in 2018, and AgNext at Colorado State University, established in 2020, as well as the influence and industry ties of the programs’ directors, Dr. Mitloehner and Dr. Kimberly Stackhouse-Lawson. We developed 20 questions to evaluate the nature, extent, and societal impacts of the relationship between individual researchers and industry groups. Using publicly available evidence, we documented how the ties between these professors, centers, and the animal agriculture industry have helped maintain the livestock industry’s social license to operate not only by generating industry-supported research, but also by supporting public relations and policy advocacy.
19 pages, The global climate change and rapid population increase are raising challenges for food security, and it demands efficient crop improvement methods that ensure superior quality and quantity of the crops. The advancements in nanotechnology can be explored to enhance sustainable crop improvement. Recently, nanotechnology has made massive revolutions in solving various problems faced by the human population, including the agriculture, environment and food sectors. In agriculture, nanotechnology has implications on every stage of farming, including seed germination, growth, harvest, processing, storage and transport of agricultural products. Nano fertilisers, nano herbicides, nano-fungicides, nano biosensors, nanoscale genetic carriers, nano-bioremediating agents and nanocomposites for packing are the novel applications of nanotechnology in the crop improvement area. Nanotechnology ensures the site-specific delivery of the nutrients in the plant's target region, which minimises the loss and increases efficiency. The reduced size of the nanomaterials offers a broader surface area for pesticides and fertilisers, drastically escalating disease and pest control in crops as they promise to overcome the shortcomings caused by traditional pesticide application. The advancement in nanotechnology is rapidly contributing to the digitalization of agriculture also. For example, nanotechnology widens the horizons of high-tech agricultural farms with the aid of biosensors.
The synthesis of nano enzymes also revolutionized the stress-tolerant mechanism of the plants by acting as an efficient antioxidant enzyme, and it has been widely used against salinity tolerance recently. The contribution of nanotechnology in effective transfer of genetic material in gene editing and genetic engineering techniques has also significantly contributed towards crop improvement. Nanobioremediation and nanophotocatalysis methods can also remove toxic substances from the environment. It is clear that, nanotechnology driven agri-food sector is expected to bloom in the near future. This review article summarizes the potential benefits of nanotechnology in agriculture and related fields, including the environment and food industry. Although nanotechnology has contributed a lot to the betterment of the world in various ways, they also face several limitations. Despite being a frontier of scientific advancement in the modern era, the negative impacts caused by nanotechnology cannot be sidelined. Therefore, this review also discusses the limitations of nanotechnology in the last section.
20 pgs., Twelve U.S. states were tasked with developing nutrient reduction strategies to help address hypoxia in the Gulf of Mexico. To better understand the kinds of messages different stakeholders in these states are likely to encounter about such strategies, we conducted a content analysis focused on the Iowa Nutrient Reduction Strategy (INRS). We examined 483 articles in two agricultural and two non-agricultural news outlets. We found that agricultural news outlets more often led with agricultural themes and more often used agricultural representatives as sources. The non-agricultural news outlets more often quoted representatives of environmental groups. News articles infrequently led with science or health themes. The volume of coverage over time in three of the four news outlets appeared followed similar issue attention cycles. Differences among the outlets may lead to differences in stakeholders’ knowledge or views about the INRS and conservation, posing challenges to consensus-building.
18 pages, Adaptation of the agricultural sector to climate change is crucial to avoid food insecurity in sub-Saharan Africa. Farmers’ perception of climate change is a crucial element in adaptation process. The aim of this study was (i) to compare farmers’ perception of climate change with actual weather data recorded in central Mali, (ii) to identify changes in agricultural practices implemented by farmers to adapt to climate change, and (iii) to investigate the link between farmers’ perception of climate change and implementation of adaptation practices. Focus group discussions and individual surveys were conducted to identify climate-related changes perceived by farmers and agricultural adaptation strategies they consider relevant to cope with these changes. A majority (>50%) of farmers perceived an increase in temperature, decrease in rainfall, shortening of growing season, early cessation of rainfall, and increase in the frequency of dry spells at the beginning of the growing season. In line with farmers’ perception, analysis of climate data indicated (i) an increase in mean annual temperature and minimum growing season temperature and (ii) a decrease in total rainfall. Farmers’ perception of early cessation of rainfall and more-frequent drought periods were not detected by climate data analysis. To cope with the decrease in rainfall and late start of the growing season, farmers used drought-tolerant cultivars and implemented water-saving technologies. Despite a perceived warming, no specific adaptation to heat stress was mentioned by farmers. We found evidence of a link between farmers’ perception of climate change and the implementation of some adaptation options. Our study highlights the need for a dialogue between farmers and researchers to develop new strategies to compensate for the expected negative impacts of heat stress on agricultural productivity.
28 pages, Large broiler chicken companies have been under pressure by consumers to reduce their carbon footprint, improve animal welfare and labor practices, and enhance environmental quality across the industry. This study examines how large broiler chicken companies have addressed sustainability within video content directed toward consumers and posted on YouTube. To conceptualize this study, we used the 1990 Farm Bill definition of agricultural sustainability. It is important to examine articulations of agricultural sustainability as company messages often incorporate sustainability philosophies and ideologies while referencing specific production practices and goals. This study used qualitative content analysis to analyze 440 videos, and framing analysis to closely examine a subset of 55 videos, from three of the largest broiler chicken companies in the United States. The framing analysis revealed that stewardship, natural state, and catalyst for change were the three most frequently used sustainability frames across the companies. These frames focus on elements of caretaking, responsibility, and public accountability, and apply these ideals to people, chickens, and profit within the organization. Few discussions of environmental stewardship were found within our analysis. While frames were not necessarily connected to production practices, each company did tend to leverage frames in ways that align with brand positioning. Companies should consider implementing discussions of how production practices affect the environment more directly, since protecting the environment and replenishing natural resources are concepts consumers associate with sustainability.
Online from publication. 2 pages., Identification of produce items cited as problematic and acceptable by the Environmental Working Group. Article indicates that more than 99 percent of produce samples tested for these reports have residue levels that are compliant with U.S. Environmental Protection Agency standards (which EWG considers insufficient).
Via online magazine. 9 pages., An old 1,300-acre oil refining site in South Philadelphia is being converted into a vast e-commerce distribution center. "But the developers of these brownfields must confront a legacy of toxic pollution and neglect of surrounding communities of color." A Philadelphia council member reports, "We have a long way to go as relates to community engagement, as well as paying attention to the environmental remediation process."
11 pages, Urban parks and green spaces are among the few places where city dwellers can have regular contact with nature and engage in outdoor recreation. Social media data provide opportunities to understand such human–environment interactions. While studies have demonstrated that geo-located photographs are useful indicators of recreation across different spaces, recreation behaviour also varies between different groups of people. Our study used social media to assess behavioural patterns across different groups of park users in tropical Singapore. 4,674 users were grouped based on the location and content of their photographs on the Flickr platform. We analysed how these groups varied spatially in the parks they visited, as well as in their photography behaviour. Over 250,000 photographs were analysed, including those uploaded and favourited by users, and all photographs taken at city parks. There were significant differences in the number and types of park photographs between tourists and locals, and between user-group axes formed from users’ photograph content. Spatial mapping of different user groups showed distinct patterns in the parks they were attracted to. Future work should consider such variability both within and between data sources, to provide a more context-dependent understanding of human–environment interactions and preferences for outdoor recreation.
