Environmental governance
2023
Policy actors address complex environmental problems by engaging in multiple and often interdependent policy issues. Policy issue interdependencies imply that efforts by actors to address separate policy issues can either reinforce (‘win–win’) or counteract (‘trade-off’) each other. Thus, if interdependent issues are managed in isolation instead of being coordinated, the most effective and well-balanced solution to the underlying problem might never be realised. This study asks if reinforcing and counteracting interdependencies have different impacts on perception and collaboration. Our empirical study of collaborative water governance in the Norrström basin, Sweden, shows that policy actors often avoid collaborating when the policy issues exhibit reinforcing interdependencies. Our evidence indicates a perceived infeasibility of acting on reinforcing interdependencies. We also find that actors do not consider counteracting interdependencies (‘trade-offs’) at all when they engage in collaboration. Further, even though actors were aware of counteracting and reinforcing interdependencies, our analyses suggest they might be less aware of the former. These findings illustrate that actors either avoid each other due to policy issue interdependencies or, at best, ignore existing interdependencies when engaging in collaboration. Our study highlights the importance of problem perception in accomplishing integrated solutions to complex environmental problems, and of how understandings of different types of interdependencies shape collaboration in environmental governance.

Defenders of the unborn : the pro-life movement before Roe v. Wade
\"Abortion is the most divisive issue in America's culture wars, seemingly creating a clear division between conservative members of the Religious Right and people who align themselves with socially and politically liberal causes. In Defenders of the Unborn, historian Daniel K. Williams complicates the history of abortion debates in the United States by offering a detailed, engagingly written narrative of the pro-life movement's mid-twentieth-century origins. He explains that the movement began long before Roe v. Wade, and traces its fifty-year history to explain how and why abortion politics have continued to polarize the nation up to the present day\"-- Provided by publisher.

Ecological and environmental citizen-science projects have enormous potential to advance scientific knowledge, influence policy, and guide resource management by producing datasets that would otherwise be infeasible to generate. However, this potential can only be realized if the datasets are of high quality. While scientists are often skeptical of the ability of unpaid volunteers to produce accurate datasets, a growing body of publications clearly shows that diverse types of citizen-science projects can produce data with accuracy equal to or surpassing that of professionals. Successful projects rely on a suite of methods to boost data accuracy and account for bias, including iterative project development, volunteer training and testing, expert validation, replication across volunteers, and statistical modeling of systematic error. Each citizen-science dataset should therefore be judged individually, according to project design and application, and not assumed to be substandard simply because volunteers generated it.

Acid rain and air pollution
2020
Because of its serious large-scale effects on ecosystems and its transboundary nature, acid rain received for a few decades at the end of the last century wide scientific and public interest, leading to coordinated policy actions in Europe and North America. Through these actions, in particular those under the UNECE Convention on Long-range Transboundary Air Pollution, air emissions were substantially reduced, and ecosystem impacts decreased. Widespread scientific research, long-term monitoring, and integrated assessment modelling formed the basis for the policy agreements. In this paper, which is based on an international symposium organised to commemorate 50 years of successful integration of air pollution research and policy, we briefly describe the scientific findings that provided the foundation for the policy development. We also discuss important characteristics of the science–policy interactions, such as the critical loads concept and the large-scale ecosystem field studies. Finally, acid rain and air pollution are set in the context of future societal developments and needs, e.g. the UN’s Sustainable Development Goals. We also highlight the need to maintain and develop supporting scientific infrastructures.

Environmental pollution by paint-based heavy metals have been continued to be a great concern. Thus, this study was aimed at investigating the levels of selected heavy metals (Ni, Cd, Cr, Zn, and Pb) in oil-based paint samples being manufactured and sold in Ethiopia. An optimized acid digestion procedure using conc. HNO

mixture by volume ratio of 3:4:1 mL, respectively, for 2 h at 200 °C were used for paint samples digestion, and the contents of heavy metals were assayed by flame atomic absorption spectroscopy. The 13 out of 14 (92.9%) analyzed paint samples had contained Pb > 90 mg/kg with the highest content of 51,200 mg/kg (dry weight) in the orange colored paint. Likewise, the levels of Cr, Ni, and Zn obtained were ranged from 43.75 to 50.00, 60.02 to 128.81, and 323.69 to 1102.16 mg/kg (dry weight), respectively, while Cd was not detected in all the paint samples. Generally, the mean contents of heavy metals in the investigated paint samples have followed the order: Pb > > Cr > Zn > Ni, demonstrating the occurrence of higher lead metal content. The elevated levels of heavy metals detected in the oil-based paint samples could be attributed to the continued usage of these metals in different form during paint manufacture. On the bases of the findings, a strict monitoring and evaluation of paints being produced in Ethiopia has been recommended so that the manufacturers comply with the national (policy issue) and/or international regulations on the levels of toxic metals in paints to ensure consumers safety.

Revision of the Common International Classification for Ecosystem Services (CICES V5.1): A Policy Brief
2018
The Common International Classification of Ecosystem Services (CICES) is widely used for mapping, ecosystem assessment, and natural capital ecosystem accounting. On the basis of the experience gained in using it since the first version was published in 2013, it has been updated for version 5.1. This policy brief summarises what has been done and how the classification can be used.

The present commentary contains a clear and simple guide designed to identify ultra-processed foods. It responds to the growing interest in ultra-processed foods among policy makers, academic researchers, health professionals, journalists and consumers concerned to devise policies, investigate dietary patterns, advise people, prepare media coverage, and when buying food and checking labels in shops or at home. Ultra-processed foods are defined within the NOVA classification system, which groups foods according to the extent and purpose of industrial processing. Processes enabling the manufacture of ultra-processed foods include the fractioning of whole foods into substances, chemical modifications of these substances, assembly of unmodified and modified food substances, frequent use of cosmetic additives and sophisticated packaging. Processes and ingredients used to manufacture ultra-processed foods are designed to create highly profitable (low-cost ingredients, long shelf-life, emphatic branding), convenient (ready-to-consume), hyper-palatable products liable to displace all other NOVA food groups, notably unprocessed or minimally processed foods. A practical way to identify an ultra-processed product is to check to see if its list of ingredients contains at least one item characteristic of the NOVA ultra-processed food group, which is to say, either food substances never or rarely used in kitchens (such as high-fructose corn syrup, hydrogenated or interesterified oils, and hydrolysed proteins), or classes of additives designed to make the final product palatable or more appealing (such as flavours, flavour enhancers, colours, emulsifiers, emulsifying salts, sweeteners, thickeners, and anti-foaming, bulking, carbonating, foaming, gelling and glazing agents).

Examining School Nutrition Policies and Their Impact on the Promotion of Low-Nutrient Foods in the Context of Sports Advertising
2024
Despite recommendations to implement nutrition standards in schools, low-nutrition and high-energy drinks are still one of the most important challenges for school management and students' purchasing and consumption behavior. In this regard, the present research aims to examine school nutrition policies and their impact on the promotion of low-nutrient foods in the context of sports advertising. A Partial Least Square (PLS) technique with SmartPLS 3.0 and bootstrapping with 500 resamples was used to examine the impact of food marketing on school nutrition policies and students' nutritional involvement. Online surveys were done through The Iranian Educational Network of student, with acronym Shad, measured on a five-point Likert scale. The survey questionnaire consisted of three scales to measure the following: school nutrition policies, Advertise low-nutrient foods, and Student nutritional involvement. Results from a sample of 382 Iranian high school students revealed that low-nutrient foods advertising has a significant impact on student consumption, and the greatest overall impact on students' nutritional involvement. School nutrition policies were affected by media, endorsement, and the environmental advertising, while school financial capabilities had the greatest direct impact on students' nutritional involvement. These findings suggest that advertising through sports media plays a mediating role in school nutrition policies and student nutritional involvement. Policy changes to restrict food marketing for young people must include both television and non-broadcast media.

Food choices are shifting globally in ways that are negatively affecting both human health and the environment. Here we consider how consuming an additional serving per day of each of 15 foods is associated with 5 health outcomes in adults and 5 aspects of agriculturally driven environmental degradation. We find that while there is substantial variation in the health outcomes of different foods, foods associated with a larger reduction in disease risk for one health outcome are often associated with larger reductions in disease risk for other health outcomes. Likewise, foods with lower impacts on one metric of environmental harm tend to have lower impacts on others. Additionally, of the foods associated with improved health (whole grain cereals, fruits, vegetables, legumes, nuts, olive oil, and fish), all except fish have among the lowest environmental impacts, and fish has markedly lower impacts than red meats and processed meats. Foods associated with the largest negative environmental impacts—unprocessed and processed red meat—are consistently associated with the largest increases in disease risk. Thus, dietary transitions toward greater consumption of healthier foods would generally improve environmental sustainability, although processed foods high in sugars harm health but can have relatively low environmental impacts. These findings could help consumers, policy makers, and food companies to better understand the multiple health and environmental implications of food choices.
