Malaria remains a major threat to public health. Long-Lasting Insecticide-treated Nets (LLINs) and Indoor Residual Spraying (IRS) have been widely adopted as important malaria prevention and control interventions and have contributed to significant reduction in malaria incidence. However, recently malaria resurgence has been reported in different countries, including Rwanda, indicating that current attempts to control and eliminate malaria may be failing due to environmental changes and changes in human behaviour. Engaging citizens in malaria prevention and control would help them to identify and prioritize their own health concerns and be able to make appropriate decisions. A citizen science approach to monitor ecological changes by providing timely information is likely to support more effective and consistent use of malaria prevention and control interventions. However, the application of citizen science in malaria prevention and control has lagged behind when comparing with areas of disease diagnosis and treatment. In addition, the determinants of participation in such a citizen science program have not been fully analyzed. This paper presents a conceptual model of likely determinants of participation in connective action (sharing and exchange of malaria-related information), effective and consistent use of malaria preventive and control measures (LLINs and IRS) and collective action (participating in public goods for malaria prevention). The model will guide future research on behavioural and contextual factors and may enhance the effective and consistent use of malaria preventive and control interventions.

Citizen science - Community participation - Malaria vector surveillance - Mosquito monitoring - Mosquito nuisance
Despite the implementation of a number of interventions aimed at controlling malaria, Rwanda is experiencing a countrywide resurgence of simple malaria cases over the past five years. To support malaria control, mosquito surveillance activities, such as systematic reporting of the distribution, the diversity and the infectivity rate of malaria vectors throughout the country, have been undertaken. However, mosquito monitoring programmes are not carried out to monitor the impact of all vector control interventions or to determine the distribution of mosquito species in all areas, especially in the remote regions of the country. With a target of reducing malaria mortality by 2020, implementation of mosquito surveillance in those regions is urgently needed as well. In this paper, a Citizen science approach as a capacity resource for malaria vector monitoring for the Rwandan National Malaria Control Programme is presented. The ultimate aim is to complement existing mosquito surveillance currently in place by providing key information on the spatio-temporal distribution of mosquito nuisance and malaria vectors. This will contribute to an insight into the ecology of malaria vectors and thereby to a better understanding of malaria transmission patterns in Rwanda.

Droughts - River salinity - Sector use - Texas - United States - Water scarcity

Hydrological droughts have a diverse range of effects on water resources. Whilst the impacts of drought on water quantity are well studied, the impacts on water quality have received far less attention. Similarly, quantifications of water scarcity have typically lacked water quality dimensions, whilst sectoral water uses are associated with both water quantity and quality requirements. Here we aim to combine these two elements, focussing on impacts of droughts on river salinity levels and including a salinity dimension in quantifications of water scarcity during drought and extreme drought conditions. The impact of historical droughts on river salinity (electrical conductivity (EC) was studied at 66 monitoring stations located across the Southern USA for 2000–2017. Salinity was found to increase strongly (median increase of 21%) and statistically significantly (p ≤ 0.05) during drought conditions for 59/66 stations compared to non-drought conditions. In a next step, a salinity dimension was added to water scarcity quantifications for 15 river basins in Texas. Water scarcity was quantified using data of sector water uses, water availability, river salinity levels and salinity thresholds for sector water uses. Results showed that the dominant factor driving water scarcity highly differed per basin. Increases in water scarcity were further compounded by drought-induced decreases in water availability, increases in sectoral water demands and increases in river water salinity. This study demonstrates that droughts are associated with important increases in river salinity, in addition to reduced water availability, and that both of these aspects should be considered when quantifying water scarcity. Alleviating water scarcity should therefore not only focus on increasing water availability and reducing water demands (quantity aspects), but also on improving water quality.

climate change impacts - Electricity generation - hydropower - solar pv - thermoelectric - wind power
The electricity sector is currently considered mainly on the emission side of the climate change equation. In order to limit climate warming to below 2 °C, or even 1.5 °C, it must undergo a rapid transition towards carbon neutral production by the mid-century. Simultaneously, electricity generating technologies will be vulnerable to climate change. Here, we assess the impacts of climate change on wind, solar photovoltaic, hydro and thermoelectric power generation in Europe using a consistent modelling approach across the different technologies. We compare the impacts for different global warming scenarios: +1.5 °C, +2 °C and +3 °C. Results show that climate change has negative impacts on electricity production in most countries and for most technologies. Such impacts remain limited for a 1.5 °C warming, and roughly double for a 3 °C warming. Impacts are relatively limited for solar photovoltaic and wind power potential which may reduce up to 10%, while hydropower and thermoelectric generation may decrease by up to 20%. Generally, impacts are more severe in southern Europe than in northern Europe, inducing inequity between EU countries. We show that a higher share of renewables could reduce the vulnerability of power generation to climate change, although the variability of wind and solar PV production remains a significant challenge.

prosumers - low-carbon electricity system - smart metering - solar panels - home batteries
This chapter discusses political consumerism in the context of a transformation towards a low-carbon electricity system. Over the past decades, deregulation, liberalisation, and privatisation have opened up spaces for Western consumers to influence the greening of energy provision and consumption via the market. Electricity system reconfiguration means a growing diversity of home-based energy devices that engage consumers with energy in new and altered ways. With the use of smart meters, solar panels, and home batteries, passive energy users change into prosumers and comanagers of the grid. To understand the power of consumers in coshaping low-carbon electricity systems, the chapter shows the need to consider the politics of intermediation and technology. The chapter concludes that energy devices afford new individual and collective forms of engaging with energy, which opens up room for political consumerism not only in relation to energy production and consumption but also with regards to digital technologies and information flows.

Challenges - Climate change - Flood-risk management - Mekong Delta - Socioeconomic developments - Solutions
Climate change and accelerating socioeconomic developments increasingly challenge flood-risk management in the Vietnamese Mekong River Delta—a typical large, economically dynamic and highly vulnerable delta. This study identifies and addresses the emerging challenges for flood-risk management. Furthermore, we identify and analyse response solutions, focusing on meaningful configurations of the individual solutions and how they can be tailored to specific challenges using expert surveys, content analysis techniques and statistical inferences. Our findings show that the challenges for flood-risk management are diverse, but critical challenges predominantly arise from the current governance and institutional settings. The top-three challenges include weak collaboration, conflicting management objectives and low responsiveness to new issues. We identified 114 reported solutions and developed six flood management strategies that are tailored to specific challenges. We conclude that the current technology-centric flood management approach is insufficient given the rapid socioecological changes. This approach therefore should be adapted towards a more balanced management configuration where technical and infrastructural measures are combined with institutional and governance resolutions. Insights from this study contribute to the emerging repertoire of contemporary flood management solutions, especially through their configurations and tailoring to specific challenges.

+1.5oC and +2oC global warming - Climate Change - Climate Change Impacts - Europe - IMPACT2C project
The Paris Agreement of the United Nations Framework Convention on Climate Change aims not only at avoiding +2°C warming (and even limit the temperature increase further to +1.5°C), but also sets long-term goals to guide mitigation. Therefore, the best available science is required to inform policymakers on the importance of and the adaptation needs in a +1.5°C warmer world. Seven research institutes from Europe and Turkey integrated their competencies to provide a cross-sectoral assessment of the potential impacts at a pan-European scale. The initial findings of this initiative are presented and key messages communicated. The approach is to select periods based on global warming thresholds rather than the more typical approach of selecting time periods (e.g., end of century). The results indicate that the world is likely to pass the +1.5°C threshold in the coming decades. Cross-sectoral dimensions are taken into account to show the impacts of global warming that occur in parallel in more than one sector. Also, impacts differ across sectors and regions. Alongside the negative impacts for certain sectors and regions, some positive impacts are projected. Summer tourism in parts of Western Europe may be favored by climate change; electricity demand decreases outweigh increases over most of Europe and catchment yields in hydropower regions will increase. However, such positive findings should be interpreted carefully as we do not take into account exogenous factors that can and will influence Europe such as migration patterns, food production, and economic and political instability.

Introduction: Highly pathogenic avian influenza (HPAI) viruses of subtype H5N8 were re-introduced into the Netherlands by late 2016, after detections in southeast Asia and Russia. This second H5N8 wave resulted in a large number of outbreaks in poultry farms and the deaths of large numbers of wild birds in multiple European countries. Methods: Here we report on the detection of HPAI H5N8 virus in 57 wild birds of 12 species sampled during active (32/5,167) and passive (25/36) surveillance activities, i.e. in healthy and dead animals respectively, in the Netherlands between 8 November 2016 and 31 March 2017. Moreover, we further investigate the experimental approach of wild bird serology as a contributing tool in HPAI outbreak investigations. Results: In contrast to the first H5N8 wave, local virus amplification with associated wild bird mortality has occurred in the Netherlands in 2016/17, with evidence for occasional gene exchange with low pathogenic avian influenza (LPAI) viruses. Discussion: These apparent differences between outbreaks and the continuing detections of HPAI viruses in Europe are a cause of concern. With the current circulation of zoonotic HPAI and LPAI virus strains in Asia, increased understanding of the drivers responsible for the global spread of Asian poultry viruses via wild birds is needed.

Diversity in the reported prevalence of metabolically healthy obesity (MHO), suggests that modifiable factors may be at play. We evaluated differences in dietary patterns and physical activity between MHO and metabolically unhealthy obesity (MUO).
Cross-sectional data of 9270 obese individuals (30–69 years) of the Lifelines Cohort Study was used. MHO was defined as obesity and no metabolic syndrome risk factors and no cardiovascular disease history. MUO was defined as obesity and ≥2 metabolic syndrome risk factors. Sex-specific associations of dietary patterns (identified by principal component analysis) and physical activity with MHO were assessed by multivariable logistic regression (reference group: MUO). Analyses were adjusted for multiple covariates.
Among 3442 men and 5828 women, 10.2% and 24.4% had MHO and 56.9% and 35.3% MUO, respectively. We generated four obesity-specific dietary patterns. Two were related to MHO, and in women only. In the highest quartile (Q) of ‘bread, potatoes and sweet snacks’ pattern, odds ratio (OR) (95% CI) for MHO was 0.52 (0.39–0.70). For the healthier pattern ‘fruit, vegetables and fish’, an OR of 1.36 (1.09–1.71) in Q3 and 1.55 (1.21–1.97) in Q4 was found for MHO. For physical activity, there was a positive association between moderate physical activity and vigorous physical activity in the highest tertile and MHO in women and men, respectively (OR 1.19 (1.01–1.41) and OR 2.02 (1.50–2.71)).
The healthier diet -characterized by ‘fruit, vegetables and fish’- and moderate physical activity in women, and vigorous physical activity in men may be related to MHO. The (refined) carbohydrate-rich ‘bread, potatoes and sweet snacks’ dietary pattern was found to counteract MHO in women.

Backcasting - Community-Led Local Development planning - Local Action Groups - Participatory approaches - Rural development planning - Stakeholders
In advanced countries, rural areas are a complex web of social, political and historical factors. In addition, several kinds of uncertainties are usually present. As a consequence, frequent mismatches arise in practise between measures and rural development goals and priorities. To overcome this pitfall, a key factor is represented by the acquisition of relevant knowledge from local stakeholders. In line with this idea, the European Commission encourages the Community-Led Local Development approach delivered by Local Action Groups. The aim of the study is to show the suitability of a participatory approach, namely backcasting, to the outline of the Local Action Plan of a specific LAG. Within this framework, a participative backcasting experience was carried out with the stakeholders of the LAG ‘Daunia Rurale’ in order to detect their needs and the strategic actions to carry out. The study provided stakeholders and policy makers with a rational approach and an operational tool to recognise the needs and design the actions for the specific endogenous potential of the investigated area. The proposed method proved to be rather innovative in CLLD contexts for the detection of expressed needs of local stakeholders and the definition of the LAP. We submitted some questionnaires to stakeholders and looking at their results (either at the ones on the niceness of the workshop or at the strategy-validation ones), some encouraging remarks can be drawn. Backcasting has been particularly helpful to local stakeholders and decision makers in identifying the steps to give a clear direction to rural development. What we learn from this case study represents a valuable outcome that can support practitioners, policy makers and researchers in understanding how to design medium- to long-term planning development strategies in rural areas.

urban agriculture - urban green space - planning - policy arrangement - Santiago de Chile
Urban green spaces are crucial for citizens’ wellbeing. Nonetheless, many Latin American cities struggle to provide sufficient and equitable green space distribution for their citizens. By looking at the Chilean capital Santiago as an example, this paper examines whether the growing urban agriculture movement provides a feasible opportunity to increase public urban green space access. It does so by using the policy arrangement approach to analyse change and stability in two policy domains: urban green space planning and urban agriculture. The paper investigates urban green spaces and urban agriculture and the role of practitioners, urban planners and policymakers. The analysis found opportunities for urban agriculture to facilitate the expansion of urban green spaces in Santiago if policy mechanisms enable private or public spaces to be maintained by citizen organizations. Such mechanisms may, however, encounter resistance from public agencies, as it is unresolved who is involved and who benefits from urban agriculture. The paper concludes that urban agriculture is an
opportunity for urban greening in Santiago, although changes are needed in how green areas are planned and conceived. Additionally, urban agriculture should not be understood as a substitute for parks but as a complementary form of green space provision with a distinctive value.

This study set out to measure what influence the type of environment has on how happy people say they feel at a certain moment in time, with the aim of formulating rules for quantifying the effect of spatial changes on wellbeing. A smartphone app was developed for use by a broad sample population in the Netherlands, with push notifications prompting people to report how they felt at a certain moment. From 1 May to 28 July of 2016, 4318 unique participants made use of this HappyHier app, filling in at least one questionnaire on location. The results show that people are happier outdoors than indoors. And when they are outdoors, they are happier in predominantly natural surroundings than in more built-up areas. Moreover, from the ratings given to the surroundings, it can be concluded that they have a more positive effect when the participants found them more restful or stimulating. People’s impressions of the beauty of their surroundings had less influence
Climate change and the vulnerability of electricity generation to water stress in the European Union

Thermoelectric generation requires large amounts of water for cooling. Recent warm periods have led to curtailments in generation, highlighting concerns about security of supply. Here we assess EU-wide climate impacts for 1,326 individual thermoelectric plants and 818 water basins in 2020 and 2030. We show that, despite policy goals and a decrease in electricity-related water withdrawal, the number of regions experiencing some reduction in power availability due to water stress rises from 47 basins to 54 basins between 2014 and 2030, with further plants planned for construction in stressed basins. We examine the reasons for these pressures by including water demand for other uses. The majority of vulnerable basins lie in the Mediterranean region, with further basins in France, Germany and Poland. We investigate four adaptations, finding that increased future seawater cooling eases some pressures. This highlights the need for an integrated, basin-level approach in energy and water policy.
