    Food insecurity in the age of neoliberalism in Turkey and its neighbors
    Öztürk, Murat ; Gür, Faik ; Jongerden, J.P. - \ 2020
    In: Food Insecurity: A Matter of Justice, Sovereignty, and Survival / Mayer, Tamar, Anderson, Molly, Abingdon : Routledge - ISBN 9781138358850 - p. 77 - 95.
    Drawing on national and international data sets, we argue in this chapter that food security is weaker in countries and regions where conflict (military unrest, civil war, etc.) and neoliberal agricultural policies coincide, regardless of how powerful their agriculture has been in the past. We contend that while high input prices and liberalized market conditions negatively affect food accessibility much more than production, the production itself is fragile because of high prices of inputs and the cost of waste, transportation, and storage, particularly in a country like Turkey, where small-scale producers dominate agrarian structures. This inevitably transforms food accessibility into a structural problem. Given that putting burdens on small-scale farming triggers rural-to-urban flight and increases unemployment rates and thus poverty, abandoning neoliberal agricultural policies and supporting small-scale farming cannot be considered just an ethical position; on the contrary, it is the solution to the food security issues in Turkey and in the region.
    The threshold of amyloid aggregation of beta-lactoglobulin : Relevant factor combinations

    Amyloid aggregates - Beta-lactoglobulin - Factor combinations - Fibrils - Statistical experimental design - Whey protein

    This study identifies critical factor combinations of pH, temperature, stirring speed, protein and ion concentration that specifically affect the lag-, and growth phase of beta-lactoglobulin amyloid aggregation and provides information on how, when and why certain factor combinations affect the onset of amyloid aggregation. Conditions at the threshold of amyloid formation were chosen to prolong the lag and growth phase for several hours. Temperature was the most important factor in all aggregation stages. Interactions between low pH and temperature in the growth phase were caused by elevated protein denaturation at low pH (DSC). Interactions between stirring speed and temperature in the lag phase were caused by viscosity-dependent shear stress (CFD-simulation). Even if none of the factor combinations could shift the onset of amyloid aggregation, important factor combinations were identified that favour the onset of amyloid aggregation. Therefore, the results of this study could be relevant for industrial production.

    Atlantic salmon - Bdnf - Dorsolateral pallium - Hippocampus - Neurogenesis - Pcna

    It is well-established that sustained exercise training can enhance brain plasticity and boost cognitive performance in mammals, but this phenomenon has not received much attention in fish. The aim of this study was to determine whether sustained swimming exercise can enhance brain plasticity in juvenile Atlantic salmon. Brain plasticity was assessed by both mapping the whole telencephalon transcriptome and conducting telencephalic region-specific microdissections on target genes. We found that 1772 transcripts were differentially expressed between the exercise and control groups. Gene ontology (GO) analysis identified 195 and 272 GO categories with a significant overrepresentation of up- or downregulated transcripts, respectively. A multitude of these GO categories was associated with neuronal excitability, neuronal signalling, cell proliferation and neurite outgrowth (i.e. cognition-related neuronal markers). Additionally, we found an increase in proliferating cell nuclear antigen (pcna) after both three and eight weeks of exercise in the equivalent to the hippocampus in fish. Furthermore, the expression of the neural plasticity markers synaptotagmin (syt) and brain-derived neurotrophic factor (bdnf) were also increased due to exercise in the equivalent to the lateral septum in fish. In conclusion, this is the first time that swimming exercise has been directly linked to increased telencephalic neurogenesis and neural plasticity in a teleost, and our results pave the way for future studies on exercise-induced neuroplasticity in fish.

    Automated Boxwood Topiary Trimming with a Robotic Arm and Integrated Stereo Vision
    Kaljaca, Dejan ; Mayer, Nikolaus ; Vroegindeweij, Bastiaan ; Mencarelli, Angelo ; Henten, Eldert Van ; Brox, Thomas - \ 2019
    In: 2019 IEEE/RSJ International Conference on Intelligent Robots and Systems, IROS 2019. - Institute of Electrical and Electronics Engineers Inc. (IEEE International Conference on Intelligent Robots and Systems ) - ISBN 9781728140049 - p. 5542 - 5549.

    This paper presents an integrated hardware-software solution to perform fully automated robotic bush trimming to user-specified shapes. In contrast to specialized solutions that can trim only bushes of a certain shape, the approach ensures flexibility via a vision-based shape fitting module that allows fitting an arbitrary mesh into a bush at hand. A trimming planning method considers the available degrees of freedom of the robot arm to achieve effective cutting motions. The performance of the mesh fitting module is assessed in multiple experiments involving both artificial and real plants with a variety of shapes. The trimming accuracy of the overall approach is quantitatively evaluated by inspecting the bush pointcloud before and after robotic trimming, and measuring the change in the deviation from the originally computed target mesh.

    For more than 10,000 years, the selection of plant and animal traits that are better tailored for human use has shaped the development of civilizations. During this period, bread wheat (Triticum aestivum) emerged as one of the world’s most important crops. We use exome sequencing of a worldwide panel of almost 500 genotypes selected from across the geographical range of the wheat species complex to explore how 10,000 years of hybridization, selection, adaptation and plant breeding has shaped the genetic makeup of modern bread wheats. We observe considerable genetic variation at the genic, chromosomal and subgenomic levels, and use this information to decipher the likely origins of modern day wheats, the consequences of range expansion and the allelic variants selected since its domestication. Our data support a reconciled model of wheat evolution and provide novel avenues for future breeding improvement.

    Aquatic ecosystems - Ecological models - Ecological risk assessment framework - Multiple stressors - Workshop

    A workshop was held in Wageningen, The Netherlands, in September 2017 to collate data and literature on three aquatic ecosystem types (agricultural drainage ditches, urban floodplains, and urban estuaries), and develop a general framework for the assessment of multiple stressors on the structure and functioning of these systems. An assessment framework considering multiple stressors is crucial for our understanding of ecosystem responses within a multiply stressed environment, and to inform appropriate environmental management strategies. The framework consists of two components: (i) problem identification and (ii) impact assessment. Both assessments together proceed through the following steps: 1) ecosystem selection; 2) identification of stressors and quantification of their intensity; 3) identification of receptors or sensitive groups for each stressor; 4) identification of stressor-response relationships and their potential interactions; 5) construction of an ecological model that includes relevant functional groups and endpoints; 6) prediction of impacts of multiple stressors, 7) confirmation of these predictions with experimental and monitoring data, and 8) potential adjustment of the ecological model. Steps 7 and 8 allow the assessment to be adaptive and can be repeated until a satisfactory match between model predictions and experimental and monitoring data has been obtained. This paper is the preface of the MAEGA (Making Aquatic Ecosystems Great Again) special section that includes three associated papers which are also published in this volume, which present applications of the framework for each of the three aquatic systems.

    The ‘living q’—an interactive method for actor engagement in transnational marine spatial planning
    Ripken, Malena ; Keijser, Xander ; Klenke, Thomas ; Mayer, Igor - \ 2018

    Communication - Interaction of actors - Marine/maritime spatial planning - Participatory approach - Q Methodology - Stakeholder engagement

    The interaction of stakeholders is regarded key in modern environmental and spatial planning. Marine/maritime spatial planning (MSP) is an emerging marine policy domain, which is of great interest worldwide. MSP practices are characterized by diverse approaches and a lack of transnational cooperation. Actors with various backgrounds have to identify mismatches and synergies to jointly aim towards coherent and coordinated practices. The ‘Living Q’ is a communication method to make actors aware systematically about their viewpoints in an interactive, communicative and playful environment, while it draws on results of a proceeding ‘Q Methodology’ study. Results from ‘Living Q’ exercises with international expert’s groups from European Sea basins show that the method is capable to foster communication and interaction among actors participating in ‘Living Q’ exercises, while having the potential to generate added value to planning processes by actor interaction in a collaborative setting.

    Blue Growth - Good Environmental Status - Maritime Spatial Planning (MSP) - Serious game - Stakeholder participation

    The 2014 EU Directive on Maritime Spatial Planning (MSP) lays down obligations for the EU Member States to establish a maritime planning process, resulting in a maritime spatial plan by 2020. Consultation should be carried out with local, national and transnational stakeholders. Stakeholder engagement in MSP is complex because of the great number and diversity of maritime stakeholders and the unfamiliarity of some of these stakeholders with MSP and its potential impact. To facilitate stakeholder engagement in MSP, the 'MSP Challenge' table top strategy game was designed and played as part of several stakeholder events in different European countries. The authors study the efficacy of the game for stakeholder engagement. Background and evaluation data of nineteen game sessions with a total of 310 stakeholders with different backgrounds were collected through post-game surveys. Furthermore, the efficacy of the game for stakeholder engagement processes, organised by competent MSP authorities in Scotland and Belgium, is studied in more detail. The results show that the board game, overall, has been a very efficient and effective way of familiarising a great diversity of stakeholders with MSP and to create meaningful interaction and learning among stakeholders in formal planning processes. However, the case studies also show that contextual factors-the level of familiarity with MSP and participants' perception to sustainability-influences the efficacy of the game.

    Knowledge co-creation - Maritime spatial planning - Planning support systems - Serious games - Sustainability

    The inherent complexity of planning at sea, called maritime spatial planning (MSP), requires a planning approach where science (data and evidence) and stakeholders (their engagement and involvement) are integrated throughout the planning process. An increasing number of innovative planning support systems (PSS) in terrestrial planning incorporate scientific models and data into multi-player digital game platforms with an element of role-play. However, maritime PSS are still early in their innovation curve, and the use and usefulness of existing tools still needs to be demonstrated. Therefore, the authors investigate the serious game, MSP Challenge 2050, for its potential use as an innovative maritime PSS and present the results of three case studies on participant learning in sessions of game events held in Newfoundland, Venice, and Copenhagen. This paper focusses on the added values of MSP Challenge 2050, specifically at the individual, group, and outcome levels, through the promotion of the knowledge co-creation cycle. During the three game events, data was collected through participant surveys. Additionally, participants of the Newfoundland event were audiovisually recorded to perform an interaction analysis. Results from survey answers and the interaction analysis provide evidence that MSP Challenge 2050 succeeds at the promotion of group and individual learning by translating complex information to players and creating a forum wherein participants can share their thoughts and perspectives all the while (co-) creating new types of knowledge. Overall, MSP Challenge and serious games in general represent promising tools that can be used to facilitate the MSP process.

    High-fat diet - Hypothalamus - Leptin - SerpinA3N

    Background: Energy homeostasis is regulated by the hypothalamus but fails when animals are fed a high-fat diet (HFD), and leptin insensitivity and obesity develops. To elucidate the possible mechanisms underlying these effects, a microarray-based transcriptomics approach was used to identify novel genes regulated by HFD and leptin in the mouse hypothalamus. Results: Mouse global array data identified serpinA3N as a novel gene highly upregulated by both a HFD and leptin challenge. In situ hybridisation showed serpinA3N expression upregulation by HFD and leptin in all major hypothalamic nuclei in agreement with transcriptomic gene expression data. Immunohistochemistry and studies in the hypothalamic clonal neuronal cell line, mHypoE-N42 (N42), confirmed that alpha 1-antichymotrypsin (α1AC), the protein encoded by serpinA3, is localised to neurons and revealed that it is secreted into the media. SerpinA3N expression in N42 neurons is upregulated by palmitic acid and by leptin, together with IL-6 and TNFα, and all three genes are downregulated by the anti-inflammatory monounsaturated fat, oleic acid. Additionally, palmitate upregulation of serpinA3 in N42 neurons is blocked by the NFκB inhibitor, BAY11, and the upregulation of serpinA3N expression in the hypothalamus by HFD is blunted in IL-1 receptor 1 knockout (IL-1R1 -/- ) mice. Conclusions: These data demonstrate that serpinA3 expression is implicated in nutritionally mediated hypothalamic inflammation.

    Decision-making processes - Integrated Water Resource Management (IWRM) - Psychosocial perspectives - Schwartz's Value Survey (SVS) - Serious games (SGs) - Social equity - Sustainability - Transcendental values - Value change - Water management

    Modern day challenges of water resource management involve difficult decision-making in the face of increasing complexity and uncertainty. However, even if all decision-makers possessed perfect knowledge, water management decisions ultimately involve competing values, which will only get more prominent with increasing scarcity and competition over resources. Therefore, an important normative goal for water management is long-term cooperation between stakeholders. According to the principles of integrated water resource management (IWRM), this necessitates that managerial decisions support social equity and intergenerational equity (social equity that spans generations). The purpose of this discussion is to formulate preliminary recommendations for the design of serious games (SGs), a potential learning tool that may give rise to shared values and engage stakeholders with conflicting interests to cooperate towards a common goal. Specifically, this discussion explores whether SGs could promote values that transcend self-interest (transcendental values), based on the contributions of social psychology. The discussion is organized in the following way. First, an introduction is provided as to why understanding values from psychological perspectives is both important for water management and a potential avenue for learning in SGs. Second, a review of the description of values and mechanisms of value change from the field of social psychology is presented. This review highlights key psychological constraints to learning or applying values. Based on this review, recommendations are made for SGs designers to considerwhen developing games forwatermanagement, in order to promote transcendental values. Overall, the main conclusions from exploring the potential of value change for IWRMthrough SGs design are as follows: 1-SGs design needs to consider how all values change systematically; 2-SGs design should incorporate the many value conflicts that are faced in real life water management, 3-SGs could potentially promote learning by having players reflect on the reasoning behind value priorities across water management situations, and 4-value change ought to be tested in an iterative SGs design process using the Schwartz's Value Survey (SVS) (or something akin to it).

    Innovative Strategies for Observations in the Arctic Atmospheric Boundary Layer (ISOBAR)-the Hailuoto 2017 campaign

    Arctic - Boundary layer remote sensing - Ground-based in-situ observations - Polar - Remotely piloted aircraft systems (RPAS) - Sea ice - Stable atmospheric boundary layer - Turbulence - Unmanned aerial vehicles (UAV)

    The aim of the research project "Innovative Strategies for Observations in the Arctic Atmospheric Boundary Layer (ISOBAR)" is to substantially increase the understanding of the stable atmospheric boundary layer (SBL) through a combination of well-established and innovative observation methods as well as by models of different complexity. During three weeks in February 2017, a first field campaign was carried out over the sea ice of the Bothnian Bay in the vicinity of the Finnish island of Hailuoto. Observations were based on ground-based eddy-covariance (EC), automatic weather stations (AWS) and remote-sensing instrumentation as well as more than 150 flight missions by several different Unmanned Aerial Vehicles (UAVs) during mostly stable and very stable boundary layer conditions. The structure of the atmospheric boundary layer (ABL) and above could be resolved at a very high vertical resolution, especially close to the ground, by combining surface-based measurements with UAV observations, i.e., multicopter and fixed-wing profiles up to 200magl and 1800magl, respectively. Repeated multicopter profiles provided detailed information on the evolution of the SBL, in addition to the continuous SODAR and LIDAR wind measurements. The paper describes the campaign and the potential of the collected data set for future SBL research and focuses on both the UAV operations and the benefits of complementing established measurement methods by UAV measurements to enable SBL observations at an unprecedented spatial and temporal resolution.

    Phylogenomics reveals multiple losses of nitrogen-fixing root nodule symbiosis

    The root nodule symbiosis of plants with nitrogen-fixing bacteria impacts global nitrogen cycles and food production but is restricted to a subset of genera within a single clade of flowering plants. To explore the genetic basis for this scattered occurrence, we sequenced the genomes of ten plant species covering the diversity of nodule morphotypes, bacterial symbionts and infection strategies. In a genome-wide comparative analysis of a total of 37 plant species, we discovered signatures of multiple independent loss-of-function events in the indispensable symbiotic regulator NODULE INCEPTION (NIN) in ten out of 13 genomes of non-nodulating species within this clade. The discovery that multiple independent losses shaped the present day distribution of nitrogen-fixing root nodule symbiosis in plants reveals a phylogenetically wider distribution in evolutionary history and a so far underestimated selection pressure against this symbiosis.

    Biofortification - Linear programming - Optifood - Vitamin A deficiency - Yellow cassava

    Objective: Introduction of biofortified cassava as school lunch can increase vitamin A intake, but may increase risk of other deficiencies due to poor nutrient profile of cassava. We assessed the potential effect of introducing a yellow cassava-based school lunch combined with additional food-based recommendations (FBR) on vitamin A and overall nutrient adequacy using Optifood (linear programming tool). Design: Cross-sectional study to assess dietary intakes (24 h recall) and derive model parameters (list of foods consumed, median serving sizes, food and food (sub)group frequency distributions, food cost). Three scenarios were modelled, namely daily diet including: (i) no school lunch; (ii) standard 5d school lunch with maize/beans; and (iii) 5d school lunch with yellow cassava. Each scenario and scenario 3 with additional FBR were assessed on overall nutrient adequacy using recommended nutrient intakes (RNI). Setting: Eastern Kenya. Subjects: Primary-school children (n 150) aged 7–9 years. Results: Best food pattern of yellow cassava-based lunch scenario achieved 100 % RNI for six nutrients compared with no lunch (three nutrients) or standard lunch (five nutrients) scenario. FBR with yellow cassava and including small dried fish improved nutrient adequacy, but could not ensure adequate intake of fat (52 % of average requirement), riboflavin (50 % RNI), folate (59 % RNI) and vitamin A (49 % RNI). Conclusions: Introduction of yellow cassava-based school lunch complemented with FBR potentially improved vitamin A adequacy, but alternative interventions are needed to ensure dietary adequacy. Optifood is useful to assess potential contribution of a biofortified crop to nutrient adequacy and to develop additional FBR to address remaining nutrient gaps.

    Towards a global governance system to protect climate migrants: taking stock
    Biermann, F. ; Boas, I.J.C. - \ 2017
    In: Research Handbook on Climate Change, Migration and the Law / Mayer, Benoit, Crépeau, Francois, Cheltenham Glos : Edward Elgar Publishing Ltd. (Research Handbooks in Clima Law series ) - ISBN 9781785366581 - p. 405 - 419.
    Climate change may compel millions of people, largely in Africa and Asia, to leave their homes to seek refuge in other places over the course of the century. Yet the current institutions, organizations and funding mechanisms, including new soft law initiatives, are not sufficiently equipped to deal with this. The situation calls for new governance. Following a review of academic and popular debates focussed on defining this issue as climate ‘refugees’ or ‘migrants’, we advance in this chapter a blueprint for a global governance architecture on the protection and voluntary resettlement of climate migrants. We argue against the extension of the definition of refugees under the 1951 Geneva Convention Relating to the Status of Refugees, and discuss the limited use of soft law mechanisms as these are largely focussed on state responsibility. Key elements of our proposal are, instead, a new legal instrument that builds on the responsibility of the international community and is specifically tailored for the needs of climate migrants—a Protocol on Recognition, Protection and Resettlement of Climate Migrants to the United Nations Framework Convention on Climate Change—as well as a separate funding mechanism, a Climate Migrant Protection and Resettlement Fund.
