Designing celebrity-endorsed behavioral interventions in conservation.

The use of celebrity endorsement in environmental conservation interventions aiming to influence human behavior has increased in recent decades. Although good practice in designing, implementing, and evaluating behavioral interventions is outlined in recent publications, guidance on developing conservation interventions with celebrity endorsement remains limited. To fill this gap, we devised a guide for decision-making relating to celebrity-endorsed behavioral interventions based on the behavioral, project design, and celebrity endorsement literatures. The guide advises conducting research to understand the behavior system in question; defining endorser selection models and celebrities based on the research; developing an endorsement strategy with the appropriate communication channels; testing the celebrity, channels, and strategy with the target audience and making adjustments as needed; and, finally, evaluating the intervention after implementation. We applied this strategy to a case study, the aim of which was to design a celebrity-endorsed intervention to reduce consumption of wild meat in Ho Chi Minh City, Vietnam. Following our guide, we found that employing evidence-based decision-making substantially enhanced our ability to understand the complexity and potential cost associated with using celebrity endorsements in behavioral interventions.

Diseño de intervenciones conductuales para la conservación apoyadas por celebridades Resumen En las últimas décadas se ha incrementado el uso del apoyo de celebridades en las intervenciones de conservación ambiental que buscan influir sobre la conducta humana. Aunque las publicaciones recientes describen las buenas prácticas en el diseño, implementación y evaluación de las intervenciones conductuales, todavía son limitadas las directrices sobre el desarrollo de intervenciones de conservación apoyadas por celebridades. Para llenar este vacío, diseñamos una guía para decidir en relación con las intervenciones conductuales apoyadas por celebridades con base en la literatura sobre las conductas, diseño de proyectos y apoyo de celebridades. La guía recomienda investigar para entender el sistema conductual en cuestión; definir los modelos de selección de patrocinadores y celebridades con base en esta investigación; desarrollar una estrategia de apoyo con los canales adecuados de comunicación; probar los canales, estrategia y celebridades con el público objetivo y realizar los ajustes necesarios; y, por último, la evaluación de la intervención posterior a la implementación. Aplicamos esta estrategia a un estudio de caso, cuyo objetivo era diseñar una intervención con apoyo de celebridades para reducir el consumo de fauna en Ciudad Ho Chi Minh, Vietnam. Con nuestra guía encontramos que el uso de decisiones basadas en evidencias mejoró sustancialmente nuestra capacidad para entender la complejidad y el costo potencial asociado con el uso de apoyo de celebridades en las intervenciones conductuales.

Global biodiversity conservation requires traditional Chinese medicine trade to be sustainable and well regulated.

Traditional Chinese medicine (TCM) is highlighted by conservation practitioners as an ongoing threat to many overharvested plant and animal species, including several charismatic threatened vertebrates. However, studies that provide evidence-based and practical recommendations on how to better regulate the TCM trade for sustainability and biodiversity conservation remain limited. China is the biggest promotor of and market for TCM and understanding the TCM trade in China is important for global biodiversity conservation. In particular, conservation researchers need to better understand how the TCM trade and its regulations interact with China's development needs and should collaborate with TCM communities to propose locally adapted suggestions to decision makers. However, progress in these areas has been restricted by language, cultural, and knowledge barriers. In this paper, we provide an overview of the current status of TCM-related regulations in China, identify weaknesses in regulation frameworks, and highlight issues that currently limit our understanding of the magnitude, dynamics, and impact of the trade. We propose changes in trade regulations, actions to enhance law enforcement, and future research directions to encourage a more sustainable TCM trade that benefits both global biodiversity conservation and TCM development.

Motivations for the use and consumption of wildlife products.

The dominant approach to combating the illegal wildlife trade has traditionally been to restrict the supply of wildlife products. Yet conservationists increasingly recognize the importance of implementing demand-side interventions that target the end consumers in the trade chain. Their aim is to curb the consumption of wildlife or shift consumption to more sustainable alternatives. However, there are still considerable knowledge gaps in understanding of the diversity of consumer motivations in the context of illegal wildlife trade, which includes hundreds of thousands of species, different uses, and diverse contexts. Based on consultation with multiple experts from a diversity of backgrounds, nationalities, and focal taxa, we developed a typology of common motivations held by wildlife consumers that can be used to inform conservation interventions. We identified 5 main motivational categories for wildlife use: experiential, social, functional, financial, and spiritual, each containing subcategories. This framework is intended to facilitate the segmentation of consumers based on psychographics and allow the tailoring of interventions-whether behavior change campaigns, enforcement efforts, or incentive programs-to the specific context in which they will be used. Underlining the importance of consumer research and collaborating with local actors is an important step toward promoting a more systematic approach to the design of demand reduction interventions.

Motivaciones para el Uso y Consumo de Productos de Fauna Resumen Tradicionalmente, la estrategia dominante para combatir el mercado ilegal de fauna ha sido restringir la oferta de productos de fauna. Aun así, los conservacionistas cada vez reconocen más la importancia de implementar intervenciones por el lado de la demanda que se enfoquen en los consumidores finales en la cadena de mercado. Su objetivo es reducir el consumo de fauna o redirigir ese consumo hacia alternativas más sustentables. Sin embargo, todavía existen vacíos de conocimiento en el entendimiento de la diversidad de motivos para los consumidores dentro del contexto del mercado ilegal de fauna, el cual incluye cientos de miles de especies, diferentes usos y contextos diversos. Con base en consultas a varios expertos con una diversidad de antecedentes, nacionalidades y taxones de enfoque desarrollamos una tipología de motivos comunes que tienen los consumidores de fauna que pueden usarse para orientar las intervenciones de conservación. Identificamos cinco categorías principales de motivos para el uso de fauna: vivencial, social, funcional, financiero y espiritual, cada uno con subcategorías. Este marco de trabajo tiene la intención de facilitar la segmentación de consumidores con base en psicográficos y permitir la personalización de las intervenciones - sean campañas de cambios en el comportamiento, esfuerzos por hacer cumplir las reglas o programas de incentivos - al contexto específico en el que serán utilizadas. Resaltar la importancia de los estudios de mercado y la colaboración con los actores locales es un paso importante hacia la promoción de una estrategia más sistemática para el diseño de intervenciones para reducir la demanda.

Characterizing efforts to reduce consumer demand for wildlife products.

The unsustainable trade in wildlife is a key threat to Earth's biodiversity. Efforts to mitigate this threat have traditionally focused on regulation and enforcement, and there is a growing interest in campaigns to reduce consumer demand for wildlife products. We aimed to characterize these behavior-change campaigns and the evidence of their impacts. We searched peer-reviewed and grey literature repositories and over 200 institutional websites to retrieve information on demand-reduction campaigns. We found 236 campaigns, mainly in the grey literature. Since the 1970s, the number of campaigns increased, although for over 15% a start date could not be found. Asia was the primary focus, although at the national level the United States was where most campaigns took place. Campaigns most often focused on a single species of mammal; other vertebrates groups, with the exception of sharks, received limited attention. Many campaigns focused on broad themes, such as the wildlife trade in general or seafood. Thirty-seven percent of campaigns reported some information on their inputs, 98% on strategies, 70% on outputs, 37% on outcomes (i.e., changes in the target audience), and 9% on impacts (i.e., biological changes or threat reduction). Information on outcomes and impacts was largely anecdotal or based on research designs that are at a high risk of bias, such as pre- and postcampaign comparisons. It was unclear whether demand-reduction campaigns had direct behavioral or biological impacts. The lack of robust impact evaluation made it difficult to draw insights to inform future efforts, a crucial part of effectively addressing complex issues, such as the wildlife trade. If demand-reduction campaigns are to become a cornerstone of the efforts to mitigate the unsustainable trade in wildlife, conservationists need to adopt more rigorous impact evaluation and a more collaborative approach that fosters the sharing of data and insights.

Caracterización de los Esfuerzos para Reducir la Demanda de Productos de Fauna Resumen El mercado insostenible de fauna es una amenaza importante para la biodiversidad del planeta. Los esfuerzos por mitigar esta amenaza se han enfocado tradicionalmente en la regulación y la ejecución, además de que existe un interés creciente por campañas para reducir la demanda del consumidor por productos de fauna. Buscamos caracterizar estas campañas de cambios de comportamiento y las evidencias de su impacto. Buscamos en los depósitos de literatura gris y aquella revisada por colegas y en más de 200 sitios web institucionales para recuperar información sobre las campañas de reducción de demanda. Encontramos 236 campañas, principalmente en la literatura gris. Desde la década de 1970, el número de campañas incrementó, aunque para más del 15% no pudimos encontrar una fecha de inicio. Asia era el foco principal, aunque a nivel nacional fueron los Estados Unidos en donde se realizaron más campañas. La mayoría de las campañas se enfocaban en una sola especie de mamífero; los demás grupos de vertebrados, excepto los tiburones, recibieron atención limitada. Muchas campañas se enfocaron en temas generales, como el mercado de fauna en general o en la industria de los mariscos. El 37% de las campañas reportaron algo de información sobre sus entradas, el 98% sobre sus estrategias, el 70% sobre su producción, el 37% sobre sus resultados (es decir, cambios en el público diana), y el 9% sobre sus impactos (es decir, cambios biológicos o reducción de la amenaza). La información sobre los resultados y los impactos en su mayoría fue anecdótica o basada en diseños de investigación que tienen un alto riesgo de sesgo, como las comparaciones pre- y post-campaña. No quedó claro si las campañas de reducción de demanda tuvieron impactos biológicos o de comportamiento directos. La falta de una evaluación fuerte de los impactos dificulta la obtención de conocimiento para informar los esfuerzos en el futuro, una parte crucial para tratar con eficiencia temas complejos, como el mercado de fauna. Si se busca que las campañas de reducción de demanda se conviertan en una piedra angular de los esfuerzos para mitigar el mercado insostenible de fauna, los conservacionistas necesitan adoptar una evaluación más rigurosa de los impactos y una estrategia más colaborativa que promueva la distribución de datos y conocimiento.

Low pangolin consumption in Hong Kong pre- and post- the COVID-19 outbreak: Conservation and health concerns both contribute to people's attitudes.

Pangolins have recently received significant media attention globally as the trade for their scales and meat is driving many species closer to extinction. As a result of this, there have been increased legal regulations placed on pangolin trade in recent years. The suggestion that pangolins may have been involved in the transmission of COVID-19 further brought the issues of pangolin consumption to the fore in 2020. However, we have little understanding of the attitudes of the general public towards pangolin consumption pre- or post the outbreak of COVID-19. We conducted surveys in Hong Kong, a critical transit hub in the trafficking routes for pangolins, in 2015 (n = 1037) and 2020 (n = 1028) to determine general attitudes towards pangolin consumption in the city, and whether these attitudes changed since the onset of COVID-19. We found low reported rates of pangolin consumption (< 1% of respondents) in both surveys, and most of the respondents who professed to eating pangolins were aged above 50. Perceptions of how trends in pangolin consumption are changing were consistent between 2015 and 2020, with 55% of the public in 2015 and 57% in 2020 believing that consumption has declined over time. In 2020, respondents cited conservation (endangered status of pangolins) and health concerns (risk of disease transmission) as the two primary reasons (> 50%) for declining attitudes toward consumption. Overall, COVID-19 does not, specifically, appear to be associated with changed perceptions of pangolin consumption in Hong Kong: > 75% of respondents stated that there is no relationship between pangolins and COVID-19, or were unsure about any such connection. Only 1% mentioned an awareness of the illegality of pangolin consumption as a reason for not consuming them. As such, our results challenge simple narratives regarding the impact of COVID-19 on pangolin consumption. We suggest that future demand reduction efforts could emphasize the conservation impact and health risks of consuming pangolins, and specifically focus on the older generations. As pangolins continue to be trafficked and threatened with extinction, further research into the perceptions and attitudes of consumers of these products is needed to inform targeted and effective interventions.

Synthesis, characterization, and application of α-Fe2 O3 @TiO2 @SO3 H photo-Fenton catalyst for photocatalytic degradation of biologically pre-treated wood industry wastewater.

The efficiency of removing chemical oxygen demand (COD) and turbidity from wood wastewater was investigated using a sequencing batch reactor (SBR) and the photo-Fenton process. A total of 94.78% of COD reduction and 99.9% of turbidity removal were observed under optimum conditions of SBR, which consisted of an organic loading rate (OLR) of 0.453 kg COD m-3  day-1 , mixed liquor suspended solids (MLSS) of 4564 mg L-1 , and cycle time of 48 h. A magnetic α-Fe2 O3 @TiO2 @SO3 H nanocatalyst was prepared as a heterogeneous Fenton reagent. The Fourier transform infrared (FT-IR), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), energy-dispersive X-ray (EDX), and elemental mapping (MAP) analyses were performed to determine the structure and morphology of synthesized photocatalyst. The response surface methodology (RSM) was used to optimize the process based on a central composite design (CCD). The maximum photocatalytic degradation of 87.54% and COD reduction of 83.35% were achieved at a dosage of 0.6 g L-1 of catalyst, 30 mg L-1 of H2 O2 , and pH of 3.5 for 45 min. The results indicated that a combination of the SBR process and α-Fe2 O3 @TiO2 @SO3 H could be used as an effective method for the treatment of wood wastewater. PRACTITIONER POINTS: A combination of the SBR and photo-Fenton process was introduced as an impressive method for wood industry wastewater treatment. The efficiencies of COD, BOD5 , NO3 -N, PO4 -P, and color removal were obtained according to the standard limits in Iran. To our knowledge, this study is the first report of the use of synthesized α-Fe2 O3 @TiO2 @SO3 H photocatalyst for the wood industry wastewater treatment.

Preparation and application of α-Fe2O3@TiO2@SO3H for photocatalytic degradation and COD reduction of woodchips industry wastewater.

In this study, we investigated the efficiency of photocatalytic degradation and chemical oxygen demand (COD) reduction from woodchips industry wastewater using α-Fe2O3@TiO2@SO3H. A magnetic α-Fe2O3@TiO2@SO3H was prepared as a heterogeneous photo-Fenton catalyst. The Fourier transform infrared (FT-IR), X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive X-ray (EDX), and elemental mapping (MAP) analyses were performed to determine the structure and morphology of synthesized photocatalysts. The response surface methodology (RSM) was used to optimize the photo-Fenton process based on a Box-Behnken design (BBD). The parameters such as catalyst dosage, H2O2 dosage, pH, and contact time on photocatalytic degradation and the reduction of COD were studied. The maximum photocatalytic degradation of 93.75% and COD reduction of 86.54% were achieved at a dosage of the catalyst of 1 g L-1, H2O2 dosage of 40 mg L-1, and a pH of 3.5 at 45 min. The kinetics of the photo-Fenton process was studied for the woodchips wastewater treatment under optimum conditions. The pseudo-second-order kinetic model for photocatalytic degradation and COD reduction was obtained. The results indicated that a α-Fe2O3@TiO2@SO3H could be used as an effective heterogeneous photocatalyst for the treatment of woodchips industry wastewater. Preparation and application of α-Fe2O3@TiO2@SO3H for photocatalytic degradation and COD reduction of woodchips industry wastewater.

Analysis of the electricity demand trends amidst the COVID-19 coronavirus pandemic.

This paper investigates the impact of COVID-19 and the global pandemic on the energy sector dynamics. Hourly electricity demand data was collected and analyzed for the province of Ontario. It is evident that health-related pandemics have a detrimental and direct influence on the concept of the smart city. This is manifested through various social, economic, environmental, technological and energy-related changes. The overall electricity demand of the province for the month of April of this year amidst pandemic conditions declined by 14%, totaling 1267 GW. A unique trend of reciprocating energy demand exists throughout the week. The post-COVID-19 indicates higher energy demand in the earlier part of the week and a lower demand in the latter part of the week. Pre-pandemic, the days of highest electricity demand were in the latter part of the work week (Wed-Fri) in addition to the weekend. Post-pandemic, the highest electricity demand occurred in the earlier part of the week (Mon-Tue). Hourly electricity demand shows a clear curve flattening during the pandemic, especially during peak hours of 7-11 in the morning and 5-7 in the evening, resulting in significant demand reductions during these periods. Lastly, due to COVID-19, GHG emission reductions of 40,000 tonnes of CO2e were achieved along with savings of $131,844 for the month of April.

Reducing demand for ineffective health remedies: overcoming the illusion of causality.

OBJECTIVE: We tested a novel intervention for reducing demand for ineffective health remedies. The intervention aimed to empower participants to overcome the illusion of causality, which otherwise drives erroneous perceptions regarding remedy efficacy. DESIGN: A laboratory experiment adopted a between-participants design with six conditions that varied the amount of information available to participants (N = 245). The control condition received a basic refutation of multivitamin efficacy, whereas the principal intervention condition received a full contingency table specifying the number of people reporting a benefit vs. no benefit from both the product and placebo, plus an alternate causal explanation for inefficacy over placebo. MAIN OUTCOME MEASURES: We measured participants' willingness to pay (WTP) for multivitamin products using two incentivized experimental auctions. General attitudes towards health supplements were assessed as a moderator of WTP. We tested generalisation using ratings of the importance of clinical-trial results for making future health purchases. RESULTS: Our principal intervention significantly reduced participants' WTP for multivitamins (by 23%) and increased their recognition of the importance of clinical-trial results. CONCLUSION: We found evidence that communicating a simplified full-contingency table and an alternate causal explanation may help reduce demand for ineffective health remedies by countering the illusion of causality.

Industry 1.61803: the transition to an industry with reduced material demand fit for a low carbon future.

Arising from a discussion meeting in September 2016, this editorial introduces a special issue on the transition to a future industrial system with greatly reduced demand for material production and attempts to synthesize the main findings. The motivation for such a transition is to reduce industrial greenhouse gas emissions, but unlike previous industrial transformations, there are no major stakeholders who will pursue the change for their own immediate benefit. The special issue, therefore, explores the means by which such a transition could be brought about. The editorial presents an overview of the opportunities identified in the papers of the volume, presents examples of actions that can be taken today to begin the process of change and concludes with an agenda for research that might support a rapid acceleration in the rate of change.This article is part of the themed issue 'Material demand reduction'.

State of the Art of the Application of Energy Storage Systems in Photovoltaic Buildings

Abstract Photovoltaic (PV) buildings are increasingly present in urban centers and can generate their own energy becoming independent of the grid, depending on their consumption profile. However, most residential and commercial consumers show their peak demand at night, when there is no photovoltaic generation, needing the electricity grid to meet the demand of these facilities. Peak demand lead to increased costs for these consumers and end up disrupting the power quality of the grid. One possible solution for these listed problems is by applying storage systems to these buildings, which is already being done in some countries and can increase the PV generation. Aiming to seek the state of the art of these systems, this article brings a review of the literature, highlighting the possible modes of operation and a real case of application in PV buildings in the world. Also are described the storage technologies most appropriate for applications in these buildings, highlighting their advantages and disadvantages. It is expected to gain greater knowledge of these systems, in order to overcome the challenges of intermittence generated by renewable sources, enabling the reduction of energy demand costs in these customers so that it can also be applied in the Brazilian scenario.
