RESUMO
Supporting transitions to sustainable, resilient agri-food systems is important to ensure stable food supply in the face of growing climate extremes. Agroecology, or diversified farming systems based on ecological principles, can contribute to such systems. Based on a qualitative case study of Nicaragua, a forerunner in agroecology, this paper unpacks an ongoing transition to agroecology, focusing on how the transition has been shaped by knowledge flows and intermediary actors. Using a niche development framework based on knowledge processes, we analyze the growth of the agroecological niche in Nicaragua over three phases of niche development. The findings show how knowledge processes' emphases have shifted over time, as have functions enacted by intermediaries. Dedicated, diversified intermediaries have been key in creating momentum for agroecology, as have individual actors moving between niche and regime. Agency in niche development has come from both niche and regime actors. Finally, we find that Nicaragua's transition to agroecology has been ambiguous: While the niche has succeeded in changing the mainstream selection environment to its favor in some arenas, transition dynamics lag in others. Drawing lessons from this ambiguity, we suggest entry points for broader systems change, such as market stimulation, value chain development, phase-out policies, and supportive policy in related arenas. We also point out possible actions for niche actors such as integration of financial and commercial actors into niches and creation of dedicated market-focused intermediaries. Our results provide evidence of an ongoing transition and action points for supporting niche development in (sustainable agri-food) transitions around the globe.

BACKGROUND: As part of malaria prevention and control efforts, the distribution and density of malaria mosquitoes requires continuous monitoring. Resources for long-term surveillance of malaria vectors, however, are often limited. The aim of the research was to evaluate the value of citizen science in providing insight into potential malaria vector hotspots and other malaria relevant information, and to determine predictors of malaria vector abundance in a region where routine mosquito monitoring has not been established to support vector surveillance. METHODS: A 1-year citizen science programme for malaria mosquito surveillance was implemented in five villages of the Ruhuha sector in Bugesera district, Rwanda. In total, 112 volunteer citizens were enrolled and reported monthly data on mosquitoes collected in their peridomestic environment using handmade carbon-dioxide baited traps. Additionally, they reported mosquito nuisance experienced as well as the number of confirmed malaria cases in their household. RESULTS: In total, 3793 female mosquitoes were collected, of which 10.8% were anophelines. For the entire period, 16% of the volunteers reported having at least one confirmed malaria case per month, but this varied by village and month. During the study year 66% of the households reported at least one malaria case. From a sector perspective, a higher mosquito and malaria vector abundance was observed in the two villages in the south of the study area. The findings revealed significant positive correlations among nuisance reported and confirmed malaria cases, and also between total number of Culicidae and confirmed malaria cases, but not between the numbers of the malaria vector Anopheles gambiae and malaria cases. At the sector level, of thirteen geographical risk factors considered for inclusion in multiple regression, distance to the river network and elevation played a role in explaining mosquito and malaria mosquito abundance. CONCLUSIONS: The study demonstrates that a citizen science approach can contribute to mosquito monitoring, and can help to identify areas that, in view of limited resources for control, are at higher risk of malaria.

BACKGROUND: Many countries, including Rwanda, have mosquito monitoring programmes in place to support decision making in the fight against malaria. However, these programmes can be costly, and require technical (entomological) expertise. Involving citizens in data collection can greatly support such activities, but this has not yet been thoroughly investigated in a rural African context. METHODS: Prior to the implementation of such a citizen-science approach, a household entomological survey was conducted in October-November 2017 and repeated one year later in Busoro and Ruhuha sectors, in southern and eastern province of Rwanda, respectively. The goal was to evaluate the perception of mosquito nuisance reported by citizens as a potential indicator for malaria vector hotspots. Firstly, mosquito abundance and species composition were determined using Centers for Disease Control and Prevention (CDC) light traps inside the houses. Secondly, household members were interviewed about malaria risk factors and their perceived level of mosquito nuisance. RESULTS: Tiled roofs, walls made of mud and wood, as well as the number of occupants in the house were predictors for the number of mosquitoes (Culicidae) in the houses, while the presence of eaves plus walls made of mud and wood were predictors for malaria vector abundance. Perception of mosquito nuisance reported indoors tended to be significantly correlated with the number of Anopheles gambiae sensu lato (s.l.) and Culicidae collected indoors, but this varied across years and sectors. At the village level, nuisance also significantly correlated with An. gambiae s.l. and total mosquito density, but only in 2018 while not in 2017. CONCLUSIONS: Perception of mosquito nuisance denoted in a questionnaire survey could be used as a global indicator of malaria vector hotspots. Hence, involving citizens in such activities can complement malaria vector surveillance and control.

BACKGROUND: Malaria control remains a challenge globally and in malaria-endemic countries in particular. In Rwanda, a citizen science programme has been set up to improve malaria control. Citizens are involved in collecting mosquito species and reporting mosquito nuisance. This study assessed what people benefit from such a citizen science programme. The analysis was conducted on how the citizen science programme influenced perceptions and behaviour related to malaria control. METHODS: This study employed a mixed-methods approach using dissemination workshops, a survey, and village meetings as the main data collection methods. Dissemination workshops and village meetings involved 112 volunteers of the citizen science programme and were conducted to explore: (1) the benefits of being involved in the programme and (2) different ways used to share malaria-related information to non-volunteers. The survey involved 328 people (110 volunteers and 218 non-volunteers) and was used to compare differences in malaria-related perceptions and behaviour over time (between 2017 and 2019), as well as between volunteers and non-volunteers. RESULTS: Malaria-related perceptions and behaviour changed significantly over time (between 2017 and 2019) and became favourable to malaria control. When the findings were compared between volunteers and non-volunteers, for perceptions, only perceived self-efficacy showed a significant difference between these two groups. However, volunteers showed significantly more social interaction, participation in malaria-related activities at the community level, and indoor residual spraying (IRS) acceptance. In addition, both volunteers and non-volunteers reported to have gained knowledge and skills about the use of malaria control measures in general, and mosquito species in particular among volunteers. CONCLUSION: The reported knowledge and skills gained among non-volunteers indicate a diffusion of the citizen science programme-related information in the community. Thus, the citizen science programme has the potential to provide individual and collective benefits to volunteers and society at large.

BACKGROUND: Malaria preventive measures, including long-lasting insecticide-treated bet nets (LLINs), indoor residual spraying (IRS), and controlling mosquito breeding sites, are key measures to achieve malaria elimination. Still, compliance with these recommended measures remains a major challenge. By applying a novel and comprehensive model for determinants of malaria prevention behaviour, this study tests how individual perceptions influence the intentions to use malaria preventive measures and explores strategies that stimulate their consistent use. METHODS: The study was carried out in the sectors of Ruhuha and Busoro, Rwanda during October and November 2017, and these were conducted into two phases. Phase one involved a questionnaire survey (N = 742), whereas Phase two employed a qualitative approach that included nine focus group discussions, seven key informant interviews, and three in-depth interviews. RESULTS: The findings of the quantitative study showed that participants very often use LLINs (66.6%), accept IRS (73.9%), and drain stagnant water in case of presence (62%). The intentions to use malaria preventive measures were consistently driven by perceived severity, perceived self-efficacy, perceived response efficacy, and subjective norms, and hindered by perceived barriers. The intentions were also positively associated with the actual use of LLINs, acceptance of IRS, and drainage of stagnant water. There is no evidence that either not having enough LLINs (ownership of at least one bed net in the household, here referred to as availability) or having sufficient LLINs (having one LLIN per two people in the household, here referred to as accessibility) moderated the relationship between behavioural intentions and actual use of LLINs. The qualitative study indicated that participants believed malaria risk to be high and perceived a high mosquito density. They also believed that repetitive malaria episodes are caused by the perceived low effectiveness of anti-malaria medications. Lack of LLINs increased the perceived added value of LLINs, and together with the increased malaria burden increased the perceived response efficacy. Participants highlighted the need to continuously mobilize and engage community members especially those who do not use LLINs when having one, and those who do not accept the spraying activities. CONCLUSION: Malaria prevention interventions should target individual perceptions to enhance consistent use of malaria preventive measures. Three strategies to improve consistent use and acceptance of these measures are highlighted: (1) ensure access to LLINs and regular spraying activities, (2) community mobilization and (3) citizen engagement in malaria prevention activities.

This paper examines the effectiveness of intrinsic and extrinsic motivations on the adoption intensity of sustainable agricultural practices (SAPs) among annual crop farmers in Chile. We use the farmers' attitude towards SAPs as a proxy of intrinsic motivation, while extrinsic motivation is represented by an economic incentive to promote the use of SAPs. The policy program we studied is administered by the Chilean Ministry of Agriculture under the name System of Incentives for the Agro-Environmental Sustainability of Degraded Soils (SIRSD-S. Sustainable behaviour was defined as the adoption of (1) minimum tillage, (2) improved fallow, (3) stubble incorporation, (4) use of manure, and (5) use of compost. A count model was estimated that showed that both sources of motivation, and the interaction between them, significantly predicted the adoption of SAPs. Farmers with low levels of intrinsic motivation depended largely on the SIRSD-S to adopt SAPs, while the incentive was ineffective for intrinsically motivated farmers who adopted more SAPs regardless the presence of extrinsic motivation. Finally, the perception of risk of soil erosion and perceived behavioural control of this risk were found to play a positive role in the adoption of SAPs.

Societies worldwide are investing considerable resources into the safe development and use of nanomaterials. Although each of these protective efforts is crucial for governing the risks of nanomaterials, they are insufficient in isolation. What is missing is a more integrative governance approach that goes beyond legislation. Development of this approach must be evidence based and involve key stakeholders to ensure acceptance by end users. The challenge is to develop a framework that coordinates the variety of actors involved in nanotechnology and civil society to facilitate consideration of the complex issues that occur in this rapidly evolving research and development area. Here, we propose three sets of essential elements required to generate an effective risk governance framework for nanomaterials. (1) Advanced tools to facilitate risk-based decision making, including an assessment of the needs of users regarding risk assessment, mitigation, and transfer. (2) An integrated model of predicted human behavior and decision making concerning nanomaterial risks. (3) Legal and other (nano-specific and general) regulatory requirements to ensure compliance and to stimulate proactive approaches to safety. The implementation of such an approach should facilitate and motivate good practice for the various stakeholders to allow the safe and sustainable future development of nanotechnology.
RESUMO
BACKGROUND: Performing a tick check after visiting nature is considered the most important preventive measure to avoid contracting Lyme disease. Checking the body for ticks after visiting nature is the only measure that can fully guarantee whether one has been bitten by a tick and provides the opportunity to remove the tick as soon as possible, thereby greatly reducing the chance of contracting Lyme disease. However, compliance to performing the tick check is low. In addition, most previous studies on determinants of preventive measures to avoid Lyme disease lack a clear definition and/or operationalization of the term "preventive measures". Those that do distinguish multiple behaviors including the tick check, fail to describe the systematic steps that should be followed in order to perform the tick check effectively. Hence, the purpose of this study was to identify determinants of systematically performing the tick check, based on social cognitive theory. METHODS: A cross-sectional self-administered survey questionnaire was filled out online by 508 respondents (Mage = 51.7, SD = 16.0; 50.2% men; 86.4% daily or weekly nature visitors). Bivariate correlations and multivariate regression analyses were conducted to identify associations between socio-cognitive determinants (i.e. concepts related to humans' intrinsic and extrinsic motivation to perform certain behavior), and the tick check, and between socio-cognitive determinants and proximal goal to do the tick check. RESULTS: The full regression model explained 28% of the variance in doing the tick check. Results showed that performing the tick check was associated with proximal goal (ß = .23, p < 0.01), self-efficacy (ß = .22, p < 0.01), self-evaluative outcome expectations (ß = .21, p < 0.01), descriptive norm (ß = .16, p < 0.01), and experience (ß = .13, p < 0.01). CONCLUSIONS: Our study is among the first to examine the determinants of systematic performance of the tick check, using an extended version of social cognitive theory to identify determinants. Based on the results, a number of practical recommendations can be made to promote the performance of the tick check.

The results of a survey and an experiment show that experiential uncertainty-people's experience of uncertainty in risk contexts-plays a moderating role in individuals' risk-related demand for government regulation and trust in risk-managing government institutions. First, descriptions of risks were presented to respondents in a survey (N = 1,017) and their reactions to questions about experiential uncertainty, risk perception, and demand for government regulation were measured, as well as levels of risk-specific knowledge. When experiential uncertainty was high, risk perceptions had a positive relationship with demand for government regulation of risk; no such relationship showed under low experiential uncertainty. Conversely, when people experience little experiential uncertainty, having more knowledge about the risk topic involved was associated with a weaker demand for government regulation of risk. For people experiencing uncertainty, this relationship between knowledge and demand for regulation did not emerge. Second, in an experiment (N = 120), experiential uncertainty and openness in risk communication were manipulated to investigate effects on trust. In the uncertainty condition, the results showed that open versus nonopen government communication about Q-fever-a zoonosis-led to higher levels of trust in the government agency, but not in in the control condition. Altogether, this research suggests that only when people experience relatively little uncertainty about the risk, knowledge provision may preclude them from demanding government action. Also, only when persons experience uncertainty are stronger risk perceptions associated with a demand for government regulation, and they are affected by openness of risk communication in forming institutional trust.

For effective sampling of mosquitoes in malaria surveillance programmes, it is essential to include attractive cues in traps. With the aim of implementing a citizen science project on malaria vectors in rural Rwanda, a handmade plastic bottle trap was designed and tested in the field to determine its effectiveness in capturing adult Anopheles gambiae sensu lato, the main malaria vector, and other mosquito species. Carbon dioxide (CO2) and light were used as attractive cues. CO2 was produced by inoculating sugar with yeast and water. Light was emitted from a torch by light-emitting diodes (LEDs). Under field conditions in rural Rwanda, three handmade trap designs were compared to Centers for Disease Control and Prevention miniature light traps (CDC-LT) in houses. The trap baited with yeast produced CO2 and light caught the highest number of mosquitoes compared to the traps baited with light alone or CO2 alone. The number of An. gambiae s.l. in the handmade trap with light and CO2 was approximately 9-10% of the number caught with a CDC light trap. This suggests that about 10 volunteers with a handmade trap could capture a similar-sized sample of An. gambiae as one CDC-LT would collect. Based on these findings, the handmade plastic bottle trap baited with sugar fermenting yeast and light represents an option for inclusion in mosquito surveillance activities in a citizen science context.

This study explores the motivational factors and barriers to participate in a citizen science program for malaria control in Rwanda. It assesses the changes in motivational factors over time and compares these factors among age and gender groups. Using a qualitative approach, this study involved 44 participants. At the initial stage, people participated in the program because of curiosity, desire to learn new things, helping others, and willingness to contribute to malaria control. As the engagement continued, other factors including ease of use of materials to report observations, the usefulness of the program, and recognition also played a crucial role in the retention of volunteers. Lack of time and information about the recruitment process, perceived low efficacy of the mosquito trap, and difficulties in collecting observations were reported as barriers to get and stay involved. Some variations in the motivational factors were observed among age and gender groups. At the initial phase, young adults and adults, as well as men and women were almost equally motivated to contribute to malaria control. For the ongoing phase, for age, the two groups were almost equally motivated by recognition of their effort. Also, the opportunity for learning was an important factor among young adults while ease of use of the materials was central for adults. For gender, the usefulness of the project, ease of use of materials, and learning opportunities were important motivational factors among women, while men were more motivated by recognition of their efforts. A framework including motivational factors and barriers at each stage of participation is presented. This framework may be used to explore motivations and barriers in future citizen science projects and might help coordinators of citizen science programs to determine whom to target, by which message, and at what stage of participation to retain volunteers in citizen science projects.

In this work, using experiments, we investigate the role of the name of a technology on the informed evaluation of that technology. We argue that a name can influence interpretations by activating cognitive structures. Using genomics-accelerated breeding as a case, we show that the name 'genomics' makes people evaluate related information as similar to genetic modification. Replacing the name 'genomics' with 'natural crossing' causes evaluations similar to those for traditional breeding. The results show that a name can have a strong influence on public attitudes, and we call for more consideration in choosing a name for a technology.
RESUMO
Consumption of insects has gained interest because it may provide a more sustainable and healthier alternative for conventional meat. However, in Western societies, insect consumption is met with resistance due to negative attitudes based on fear and disgust. To further understand consumers' willingness to try insect meat, a 2 (meat type: bovine vs. insect) × 2 (product type: common vs. uncommon) experiment was conducted (n = 130). Four food choice factors were expected to mediate the effect of meat type and product type on willingness to try: health, sensory appeal, risk perception, and disgust. Results indicate that meat type had no effect on willingness to try. Relative to bovine meat, insect meat was perceived as both healthier and more disgusting, which could explain the absence of a meat type effect. Unexpectedly, use of insects in common products (burgers) as compared to uncommon products (skewers) was met with a lower willingness to try. Also, common products with insect meat was considered to be less healthy and more disgusting, compared to uncommon products with insect meat.

BACKGROUND: The public's negative attitudes towards household insects drive tolerance for these insects and their control. Tolerance levels are important in integrated pest management (IPM), as are pest knowledge and information. The risk information seeking and processing (RISP) model describes the relationships between personal factors and information-seeking behaviour. We combined IPM and RISP to determine important relationships between factors driving insect tolerance levels and information-seeking behaviour through an online survey and tested whether this model is valid and generally applicable. RESULTS: Relationships between variables from both IPM and RISP models were tested for seven insect species. Tolerance levels were measured with two factors: willingness to pay for pest control and whether insects are tolerated. Willingness to pay for control was positively affected by age, experience, risk perception, insect characteristics, and negative emotions and affected behavioural intention, by influencing information sufficiency and information-seeking behaviour. Tolerability was influenced by perception of insect characteristics and determines whether control measures are taken. CONCLUSION: It was possible to combine the RISP and IPM models. Relevant driving factors were a person's age, experience, risk perception, negative affective responses, tolerance levels, relevant channel beliefs about online forums, information sufficiency and information-seeking behaviour. There was, however, variation in important factors between different insects. © 2017 The Authors. Pest Management Science published by John Wiley & Sons Ltd on behalf of Society of Chemical Industry.

Current sanitation systems are inherently limited in their ability to address the new challenges for (waste)water management that arise from the rising demand to restore resource cycles. These challenges include removal of micropollutants, water (re)use, and nutrient recovery. New opportunities to address these challenges arise from new sanitation, a system innovation that combines elements of source separation, local treatment and reuse, and less use of water. New sanitation is applied, but not yet widespread, in several residential areas in Europe. Implementation is hindered by the lack of insight into the general public's willingness to engage in new sanitation, and the resulting uncertainty about this among decision makers and other stakeholders in wastewater management. Using value-belief-norm theory as a conceptual lens, this paper addresses the individual motivations (pro-environmental personal norms) and personal drivers (benefits) and barriers (risks) for acceptance of new sanitation by the Dutch general public. The results of an online survey (Nâ¯=â¯338) indicated that both pro-environmental personal norms and risk and benefit perceptions predict consumers' willingness to accept new sanitation. More specifically, they showed that consumer acceptance is driven by perceived risks relating to the housing market and the need to change behavior, but also by environmental benefits. Overall, new sanitation was favorably evaluated by respondents: 64% indicated that they would likely use new sanitation if they were owner-occupiers. The results of this explorative study are discussed in light of the development of novel sanitation systems that are sensitive to perceptions of end-users and other key stakeholders.

The present research examines the impact of achievement goals on task-related information exchange. Studies 1 and 2 reveal that relative to those with mastery goals or no goal, individuals pursuing performance goals were less open in their information giving to exchange partners. Study 2 further clarifies this effect of achievement goals by showing that performance goals generate an exploitation orientation toward information exchange. Furthermore, relative to individuals with mastery goals or no goal, people pursuing performance goals enhanced their task performance by utilizing more high-quality information obtained from their exchange partner (Study 1) and protected their task performance by more rigorously disregarding received low-quality information (Study 2).

This multisource field study applied belongingness theory to examine whether thwarted belonging, defined as the perceived discrepancy between one's desired and actual levels of belonging with respect to one's coworkers, predicts interpersonal work behaviors that are self-defeating. Controlling for demographic variables, job type, justice constructs, and trust in organization in a multilevel regression analysis using data from 130 employees of a clinical chemical laboratory and their supervisors, the authors found that employees who perceive greater levels of desired coworker belonging than actual levels of coworker belonging were more likely to engage in interpersonally harmful and less likely to engage in interpersonally helpful behaviors. Implications for the application of belongingness theory to explain self-defeating behaviors in organizations are discussed.

The current study investigated the determinants of consumers' intention to purchase meat from mobile slaughter units (MSU). The theory of planned behavior (TPB) and the value belief norm theory (VBN) were used as conceptual lenses to guide this investigation. We conducted a survey among 329 respondents in the Netherlands who buy meat for themselves and/or for others. The results indicated that (1) TPB and VBN explain a high proportion of the variance in consumers' intention to buy MSU meat, and that (2) an extended TPB that includes peoples' attitude, personal norm, subjective norm, and perceived behavioral control turned out to be the best model to predict willingness to buy MSU meat. Further implications for future research and practice are discussed.

Low public acceptance hinders the successful introduction of biotechnological innovations, such as genetically modified foods or vaccinations against infectious diseases. Earlier studies indicated that a lack of knowledge is not a key barrier to acceptance. This was confirmed in the current study, which examined an integrated theoretical model tested among 579 participants from the Dutch public. The results suggest that communication strategies should instead target attitudes, social norms, and risk perceptions, and appeal to people's tendency (or lack thereof) to be innovative.
