The Impact

The grapevine is subject to high number of fungal and viral diseases, which are responsible for important economic losses in the global wine sector every year. These pathogens deteriorate grapevine berry quality either directly via the modulation of fruit metabolic pathways and the production of endogenous compounds associated with bad taste and/or flavor, or indirectly via their impact on vine physiology. The most common and devastating fungal diseases in viticulture are gray mold, downy mildew (DM), and powdery mildew (PM), caused, respectively by Botrytis cinerea, Plasmopara viticola, and Erysiphe necator. Whereas B. cinerea mainly infects and deteriorates the ripening fruit directly, deteriorations by DM and PM are mostly indirect via a reduction of photosynthetic leaf area. Nevertheless, mildews can also infect berries at certain developmental stages and directly alter fruit quality via the biosynthesis of unpleasant flavor compounds that impair ultimate wine quality. The grapevine is furthermore host of a wide range of viruses that reduce vine longevity, productivity and berry quality in different ways. The most widespread virus-related diseases, that are known nowadays, are Grapevine Leafroll Disease (GLRD), Grapevine Fanleaf Disease (GFLD), and the more recently characterized grapevine red blotch disease (GRBD). Future climatic conditions are creating a more favorable environment for the proliferation of most virus-insect vectors, so the spread of virus-related diseases is expected to increase in most wine-growing regions. However, the impact of climate change on the evolution of fungal disease pressure will be variable and depending on region and pathogen, with mildews remaining certainly the major phytosanitary threat in most regions because their development rate is to a large extent temperature-driven. This paper aims to provide a review of published literature on most important grapevine fungal and viral pathogens and their impact on grape berry physiology and quality. Our overview of the published literature highlights gaps in our understanding of plant-pathogen interactions, which are valuable for conceiving future research programs dealing with the different pathogens and their impacts on grapevine berry quality and metabolism.

The Impact

AbstractClimate change will have a profound effect on vine growing worldwide. Wine quality will also be affected, which will raise economic issues. Possible adaptations may result from changes in plant material, viticultural techniques, and the wine-making process. Relocation of vineyards to cooler areas and increased irrigation are other options, but they may result in potential conflicts for land and water use. Grapes are currently grown in many regions around the world, and growers have adapted their practices to the wide range of climatic conditions that can be found among or inside these areas. This knowledge is precious for identifying potential adaptations to climate change. Because climate change affects all activities linked to wine production (grape growing, wine making, wine economics, and environmental issues), multidisciplinary research is needed to guide growers to continue to produce high-quality wines in an economical and environmentally sustainable way. An example of such an interdisciplinary study is the French LACCAVE (long-term adaptation to climate change in viticulture and enology) project, in which researchers from 23 institutes work together on all issues related to the impact of climate change on wine production.

The Impact

<p>Biodiversity loss (including land degradation) and climate change are the biggest challenges of our time, and they have a strong two-way interaction. Climate induced geo-hazards, such as landslides and floods, are likely to to increase in the near future due to climate change causing more rainfall and more frequent extreme weather events. On the other hand, biodiversity is continuously threatened by climate-induced geo-hazards.</p><p>PlaNet is a multidisciplinary network that gathers experts in the field of nature-based solutions (NBS) that use vegetation for mitigating rainfall-induced geohazards, with a focus on shallow landslides and erosion. Vegetating slopes or stream banks are also key for ecological restoration and rewilding, as well as buffer-zones for agricultural lands.</p><p>PlaNet pools expertise from leading research organisations within geosciences and provides a collaborative environment for addressing these problems using sustainable, nature-based solutions.</p><p>The Norwegian Geotechnical Institute (NGI) coordinates PlaNet, and the network has 5 research organisations and 7 universities as initial core partners. PlaNet is multidisciplinary, encompassing a wide range of expertise areas, such as geotechnical engineering, hydrology, soil science, plant ecology, biodiversity, and agronomy.</p><p>The objectives of PlaNet are to share research on how vegetation-based solutions can be used to mitigate climate changes, influence policy nationally, internationally prepare the grounds for a European policy to be adopted by future research programmes and to foster multidisciplinary and international research-exchange and facilitate participation of industry and entrepreneurs.</p><p>PlaNet provides an appropriate knowledge exchange forum that is urgently needed for future implementation of vegetation and nature-based solutions for mitigating climate-related geohazards, while protecting biodiversity. This forum does not only benefit researchers but also provide the knowledge needed for policy makers, entrepreneurs and suppliers, and to the general public for education and information.</p><p>Activities in the network include knowledge dissemination, through filming and distributing virtual laboratory/site tours to real case study sites where NBS have been implemented, to generate interest and enhance the impact of PlaNet beyond the "research" boundaries. As well as to promote the international presence of Norwegian PlaNet partners. Activities also include publishing articles in national and international professional journals and magazines.</p><p>PlaNet contributes to encourage Norwegian researchers to participate more widely in, and exert greater influence on, global research on climate and the environment and it contributes to Norway gaining a leading position in Europe for development and use of nature-based solutions. It also contributes to strengthen the international relationship among Norwegian research institutes and universities developing expertise in different aspects of nature-based solutions. It promotes and supports research on vegetation-based solutions for mitigating climate-induced geohazards and contributes to the use of nature-based solutions and ecological restoration.</p>

The Impact

The analysis of climate change in the Russian Federation has been carried out. It has been shown that the major climate change is occurring in the Arctic zone — increased emissions of carbon dioxide and methane, deep permafrost thawing. Due to the change of climatic conditions, improvement of the ecological situation and wide use of biological cleaning systems for a treatment of industrial and household effluents a change of biological systems is taking place. Natural selection of microorganisms capable to use as a nutritious substratum such previously inert materials as polyethylene and polypropylene is intensified. The change of climatic conditions in which complex technical systems are operated, and the impact of biological and ecological factors on these systems dictate the need for revision of approaches to creation, design and operation of appropriate technical means. Actions for standardization of procedure for products climatic qualification taking into account the influence of newly forming climatic, ecological and biological conditions will allow considerably reduce economic losses from corrosion, aging and biodeterioration of complex technical systems. The work has been carried out in the frame of implementation of complex research area 18 “Climatic Tests for Safety Provision and Protection from Corrosion, Aging and Biodeterioration of Materials, Constructions and Complex Technical System in Natural Environments” (“Strategic Areas for Development of Materials and Their Treatment Technologies for the Period until 2030”).

The Impact

Climate change and global warming are of great concern to agriculture worldwide and are among the most discussed issues in today’s society. Climate parameters such as increased temperatures, rising atmospheric CO2 levels, and changing precipitation patterns have significant impacts on agricultural production and on agricultural insect pests. Changes in climate can affect insect pests in several ways. They can result in an expansion of their geographic distribution, increased survival during overwintering, increased number of generations, altered synchrony between plants and pests, altered interspecific interaction, increased risk of invasion by migratory pests, increased incidence of insect-transmitted plant diseases, and reduced effectiveness of biological control, especially natural enemies. As a result, there is a serious risk of crop economic losses, as well as a challenge to human food security. As a major driver of pest population dynamics, climate change will require adaptive management strategies to deal with the changing status of pests. Several priorities can be identified for future research on the effects of climatic changes on agricultural insect pests. These include modified integrated pest management tactics, monitoring climate and pest populations, and the use of modelling prediction tools.

The Impact

Every aspect of human operations faces a wide range of risks, some of which can cause serious consequences. By the start of 21st century, mankind has recognized a new class of risks posed by climate change. It is obvious, that the global climate is changing, and will continue to change, in ways that affect the planning and day to day operations of businesses, government agencies and other organizations and institutions. The manifestations of climate change include but not limited to rising sea levels, increasing temperature, flooding, melting polar sea ice, adverse weather events (e.g. heatwaves, drought, and storms) and a rise in related problems (e.g. health and environmental). Assessing and managing climate risks represent one of the most challenging issues of today and for the future. The purpose of the risk modeling system discussed in this paper is to provide a framework and methodology to quantify risks caused by climate change, to facilitate estimates of the impact of climate change on various spheres of human activities and to compare eventual adaptation and risk mitigation strategies. The system integrates both physical climate system and economic models together with knowledge-based subsystem, which can help support proactive risk management. System structure and its main components are considered. Special attention is paid to climate risk assessment, management and hedging in the Arctic coastal areas.

The Impact

In this meta-analytic review, we investigated the effects of technology supports on the acquisition of shopping skills for students with intellectual and developmental disabilities (IDD) between the ages of 5 and 24. Nineteen single-case experimental research studies, presented in 15 research articles, met the current study’s inclusion criteria and the What Works Clearinghouse (WWC) standards. An analysis of potential moderators was conducted, and we calculated effect sizes using Tau-U to examine the impact of age, diagnosis, and type of technology on the reported outcomes for the 56 participants. The results from the included studies provide evidence that a wide range of technology interventions had a positive impact on shopping performance. These positive effects were seen for individuals across a wide range of ages and disability types, and for a wide variety of shopping skills. The strongest effect sizes were observed for technologies that provided visual supports rather than just auditory support. We provide an interpretation of the findings, implications of the results, and recommended areas for future research.

AbstractResearch about vection (illusory self-motion) has investigated a wide range of sensory cues and employed various methods and equipment, including use of virtual reality (VR). However, there is currently no research in the field of vection on the impact of floating in water while experiencing VR. Aquatic immersion presents a new and interesting method to potentially enhance vection by reducing conflicting sensory information that is usually experienced when standing or sitting on a stable surface. This study compares vection, visually induced motion sickness, and presence among participants experiencing VR while standing on the ground or floating in water. Results show that vection was significantly enhanced for the participants in the Water condition, whose judgments of self-displacement were larger than those of participants in the Ground condition. No differences in visually induced motion sickness or presence were found between conditions. We discuss the implication of this new type of VR experience for the fields of VR and vection while also discussing future research questions that emerge from our findings.

The Impact

High concentrations of ozone (O3) can have significant impacts on the health and productivity of agricultural and forest ecosystems, leading to significant economic losses. In order to estimate this impact under a wide range of environmental conditions, the mechanisms of O3 impacts on physiological and biochemical processes have been intensively investigated. This includes the impact on stomatal conductance, the formation of reactive oxygen species and their effects on enzymes and membranes, as well as several induced and constitutive defence responses. This review summarises these processes, discusses their importance for O3 damage scenarios and assesses to which degree this knowledge is currently used in ecosystem models which are applied for impact analyses. We found that even in highly sophisticated models, feedbacks affecting regulation, detoxification capacity and vulnerability are generally not considered. This implies that O3 inflicted alterations in carbon and water balances cannot be sufficiently well described to cover immediate plant responses under changing environmental conditions. Therefore, we suggest conceptual models that link the depicted feedbacks to available process-based descriptions of stomatal conductance, photosynthesis and isoprenoid formation, particularly the linkage to isoprenoid models opens up new options for describing biosphere-atmosphere interactions.

The Impact

International Baccalaureate (IB) programmes are growing rapidly worldwide, driven in part by their global reputation and concept-driven, inquiry-based approach to teaching and learning. This thematic review of a range of literature sources examines the impact of IB programmes on teaching and learning, highlighting trends, challenges, and benefits. Findings of the review revealed that most of the studies, both qualitative and quantitative, examined stakeholders’ perspectives or self-reported experiences of IB programmes; a very small number used research designs that control for confounding factors or allow causal inferences to be drawn. A wide range of stakeholders report that IB programmes develop research and critical thinking skills, intercultural appreciation and global awareness, as well as cultivate collaborative working cultures and creative pedagogical practices among teachers. Challenges include extra demands on teachers for lesson planning and assessment, additional stress for teachers and students, and competing demands and expectations with national requirements. Recommendations are provided which may guide future research endeavours.
