    Het klimaat verandert en de zeespiegel stijgt. Daarover bestaat geen twijfel, hoewel er nog wel onzekerheid bestaat over de snelheid van de veranderingen, en soms over de precieze richting daarvan. Ondanks deze onzekerheden is het verstandig te anticiperen op wat komen gaat. Daar zijn we in Nederland dan ook al volop mee bezig. In de afgelopen jaren is in diverse projecten en programma’s zoals Kennis voor Klimaat, het Deltaprogramma en STOWA/Deltaproof, veel kennis opgedaan over mogelijke strategieën om ons aan te passen aan de veranderende klimatologische omstandigheden. Maar hoe zien dergelijke adaptatiestrategieën er precies uit en hoe kom je tot een concrete invulling? Dit rapport geeft een overzicht van concrete maatregelen die kunnen worden ingezet bij adaptatie in verband met de toenemende overstromingsrisico’s. Het rapport richt zich vooral op wat gemeenten, provincies en waterschappen kunnen doen.
    Dietary supplement use and colorectal tumors : from prevention to diagnosis

    Background: Expert guidelines formulated by the World Cancer Research Fund and the American Institute for Cancer Research (WCRF/AICR) advised no use of dietary supplements for cancer prevention. However, it is unclear whether those recommendations also apply to populations at high risk for incident or recurrent colorectal tumors specifically, since dietary supplement use is ubiquitous in western countries where colorectal tumors are common. Furthermore, before the association between dietary supplement use and recurrence and survival in colorectal cancer patients can be examined, more information about the consistency of dietary supplement use is needed, as it is plausible that use varies over time after colorectal cancer diagnosis. This thesis focuses on the association between dietary supplement use and colorectal tumor risk and recurrence in the general population and in high-risk populations, and describes the consistency of use in patients who were diagnosed with colorectal cancer.

    Methods and results: First, we conducted a systematic literature review with meta-analyses of observational studies about the association between dietary supplement use and colorectal cancer risk. Our findings suggested inverse associations between multivitamins (use versus no use: RR=0.92; 95% CI 0.87–0.97, calcium supplements (use versus no use: RR=0.86; 95% CI 0.79–0.95) and colorectal cancer risk, while the association for other supplements and colorectal cancer risk was inconsistent.

    Second, we investigated the role of dietary supplements in recurrence of colorectal adenomas and advanced colorectal adenomas in a prospective cohort study of 565 patients with a history of sporadic colorectal adenomas. Dietary supplement was not associated with total adenoma recurrence (HR=1.03; 95% CI 0.79–1.34).

    Third, dietary supplement use and colorectal adenoma risk was examined in a prospective cohort study among 470 individuals with Lynch syndrome. No associations were found between dietary supplement use (HR=1.18; 95% CI 0.80–1.73) and colorectal adenoma risk in these individuals.

    Finally, in an ongoing prospective cohort study among incident colorectal cancer patients we evaluated whether dietary supplement use was consistent over time. Dietary supplement use was extensively assessed with a detailed self-administered questionnaire at diagnosis, six months and two years post-diagnosis. We observed that dietary supplement use among 160 colorectal cancer patients was common at all time points, but use was inconsistent from diagnosis to two years post-diagnosis.

    Conclusion: The results in this thesis do not point toward a preventive nor a harmful role for dietary supplement use in colorectal tumor risk and recurrence in the general population and in high-risk populations for colorectal cancer. However, dietary supplement use appeared to be inconsistent over time after colorectal cancer diagnosis, and use should be repetitively assessed over time. Since dietary supplement use is rising in countries where colorectal tumors are prevalent and the incidence of colorectal tumors will increase due to screening practices, research on the role of dietary supplement use for primary or tertiary prevention of colorectal tumors should continue in which use should be repetitively and comprehensively assessed.

    The aim of this report is to provide EFSA with probabilistic models for quantitative pathway analysis of plant pest introduction for the EU territory through non-edible plant products or plants. We first provide a conceptualization of two types of pathway models. The individual based PM simulates an individual consignment (or a population of such consignment) by describing the stochastic change in the state of the individual consignment over time and space. The flow-based PM, simulates the flow of infested product over time and space, without distinguishing individual consignments. We show how these two conceptualisations are mathematically related, and present, as a show case, both models for cut flowers. Second, we developed PMs for five product groups: round wood, sawn wood, cut flowers, plants for planting and seeds. For each product group we have developed a case-study (combination of product, origin and pest) to illustrate the use of the pathway models: (1) oak wood from the USA and Ceratocystis fagacearum, (2) Coniferous sawn wood from China and Bursaphelenchus xylophilus, (3) Cut orchids from Thailand and Thrips palmi, (4) Pot orchids from Thailand and Thrips palmi, and (5) Tomato seeds and Clavibacter michiganensis subsp. michiganensis from outside the European Union. An uncertainty analysis on the models shows that the pest species-specific parameters appear to be sensitive and uncertain. Third, a practical guidance is provided on i) how to develop a PM, ii) the application of PMs in @Risk (a plugin for MS Excel), and iii) application in R. Finally, future research topics are defined. Further work is needed on interpretation of results, linking quantitative outcomes of pathway modelling to pest risk scoring guidance, and evaluation of management options using pathway models.

    Economic analysis of flood risk management strategies has become more complex due to climate change. This thesis investigates the impact of climate change on investment in flood risk reduction, and applies optimisation methods to support identification of optimal flood risk management strategies. Chapter 2 provides an overview of cost-benefit analysis (CBA) of flood risk management strategies under climate change uncertainty and new information. CBA is applied to determine optimal dike heights under climate change uncertainty and new information in Chapter 3. Chapter 4 studies impacts of rainfall variability and changing return periods of rainfall extremes on cost-effective adaptation of water systems to climate change given a flood protection standard. Chapter 5 departs from expected cost minimisation, and applies the minimax regret decision criterion to identify maximum regret minimising flood risk management strategies under the arrival of new climate impact information. The thesis concludes that the modelling of new climate-related information may improve an economic analysis of flood risk management strategies

    This publication, A Best Practices Notebook for Disaster Risk Reduction and Climate Change Adaptation: Guidance and Insights for Policy and Practice from the CATALYST Project is one of two main CATALYST knowledge products that focus on the transformative approaches and measures that can support Disaster Risk Reduction (DRR) and Climate Change Adaptation (CCA). It is complemented by the Best Practices Papers: Before Disaster Strikes – Transformations in Practice and Policy prepared for each of the four CATALYST regions (South and Southeast Asia, Mediterranean Europe, East and West Africa, and Central America and the Caribbean). While the previous publications present the practices considered by stakeholders to be among the most important in each region, this publication summarises the key results of the entire project from a multi-regional perspective. In doing so, it focuses on some of the most essential themes that have emerged from the CATALYST Think Tank over the last two years: ecosystems-based DRR/CCA; mainstreaming DRR/CCA; urban DRR; drought risk management for agriculture; climate risk insurance; small island developing states, and how the Hyogo Framework for Action should be followed up, as well as how to continue the CATALYST legacy.
    Evaluating the effect of flood damage-reducing measures: a case study of the unembanked area of Rotterdam, the Netherlands

    Empirical evidence of increasing flood damages and the prospect of climatic change has initiated discussions in the flood management community on how to effectively manage flood risks. In the Netherlands, the framework of multi-layer safety (MLS) has been introduced to support this risk-based approach. The MLS framework consists of three layers: (i) prevention, (ii) spatial planning and (iii) evacuation. This paper presents a methodology to evaluate measures in the second layer, such as wet proofing, dry proofing or elevating buildings. The methodology uses detailed land-use data for the area around the city of Rotterdam (up to building level) that has recently become available. The vulnerability of these detailed land-use classes to flooding is assessed using the stage–damage curves from different international models. The methodology is demonstrated using a case study in the unembanked area of Rotterdam in the Netherlands, as measures from the second layer may be particularly effective there. The results show that the flood risk in the region is considerable: EUR 36 million p.a. A large part (almost 60 %) of this risk results from industrial land use, emphasising the need to give this category more attention in flood risk assessments. It was found that building level measures could substantially reduce flood risks in the region because of the relatively low inundation levels of buildings. Risk to residential buildings would be reduced by 40 % if all buildings would be wet-proofed, by 89 % if all buildings would be dry-proofed and elevating buildings over 100 cm would render the risk almost zero. While climate change could double the risk in 2100, such building level measures could easily nullify this effect. Despite the high potential of such measures, actual implementation is still limited. This is partly caused by the lack of knowledge regarding these measures by most Dutch companies and the legal impossibility for municipalities to enforce most of these measures as they would go beyond the building codes established at the national level.

    Pesticide risk reduction through registration of less hazardous pesticides and the promotion of nonchemical pest and disease control approaches such as Integrated Pest Management (IPM) is essential for a more sustainable plant production in East Africa in order to enhance both export market access and food safety. This study gives guidance for the transition towards a further adoption of IPM in East Africa. It describes the current situation and presents the incentives for and obstacles to the East African countries. There are various initiatives to strengthen the institutional, economic, political and social aspects in the East African region. The East African Community (EAC) is working jointly on different themes, including agricultural development and reducing trade barriers. Also, in the field of pesticide legislation further steps should be made. A regional approach in establishing a framework for the registration of pesticides and bio pesticides and natural liquids would be a first step in creating the institutional environment to make actions more effective and efficient.

    Over the last few decades, the alarming increase in both the frequency and impact of disasters has drastically affected the livelihoods of people living in both developing and developed countries. A growing number of weather-related hazards can be observed such as floods, droughts and forest fires. Climate change most likely contributes to this rise, as well as people’s mounting vulnerability due to, for instance, population growth, insecure land rights, rising food prices and unemployment. Over the last few years a sense of urgency has emerged among platforms and networks related to Disaster Risk Reduction (DRR), Climate Change Adaptation (CCA) and Poverty Reduction (PR) to integrate the three domains in order to cope with future risks more effectively. This handbook is designed to encourage thinking and provide insights and ideas about how to design well-integrated, step-by-step actions and strategies to foster resilience at the local level. The handbook aims to support students and young professionals in their DRR, CCA and PR related work and secondly to acquaint policymakers involved in these three domains with the integration issue and help them to take a resilience 2.0 approach into their (present or future) daily work.
    Community-Managed Disaster Risk Reduction : Investing in Resilience. A report prepared for Cordaid

    Cordaid has been supporting community-managed disaster risk reduction (CMDRR) and drought cycle management (DCM) in the Horn of Africa for eight years. Many evaluations have pointed to successful outcomes but quantitative data are scarce. The aim of this study was to verify the extent to which Cordaid’s CMDRR/DCM work has contributed to building more resilient communities. Cordaid wanted to know more precisely what its added value is, compared to relief assistance. This was considered particularly timely given the recent (severe) drought situation in the Horn of Africa. This report is based on work undertaken in Kenya and Ethiopia in late 2011 and early 2012. A wealth of largely qualitative evidence is presented to support the finding that CMDRR can indeed build resilience. Importantly, many CMDRR communities themselves attest to being more resilient as a result of CMDRR. However, measuring those results is difficult. In common with other approaches, CMDRR helps communities strengthen physical assets for resilience (water development, pastures, animal health care etc.) but its “edge” may be in the emphasis it places on intangible assets (capacity-building in “soft” skills such as representative process for community organisation and planning) – as the means by which to ensure that interventions are demand-led, well-managed by the community and hence sustainable. Measuring the potentially far-reaching impacts of those “process” assets requires the development of robust monitoring systems to follow communities over a number of years.

    fresh meat - empirical-research - risk reduction - social trust - consumption - safety - confidence - information - behavior - attitude
    Research indicates that consumers are particularly concerned about the safety of meat. More highly processed meat is perceived as more unsafe than fresh or natural meats, i.e., consumers trust processed meat less. This paper studies the relationship between perceived trust and day-to-day purchase behavior for meat, giving special attention to the degree of meat processing. Controlling for trust in food chain actors and demographic and socio-economic variables, actual meat purchases of Canadian households are linked to answers from a commissioned food attitudes survey completed by the same households. Expenditures for processed and total meat (but not for fresh meat) are significantly different by three levels of trust in the food industry. Consumer with the lowest trust levels consume less (especially of processed meat) compared to those with higher trust levels. However, in a multivariate setting, trust shows no effect on fresh or processed meat purchases with or without demographic and socio-economic control variables, suggesting that the impact of trust on meat purchases is only small. However, the low trusting consumer segment could potentially be a target for marketing strategies focused on reputation and quality to increase sales in this particular group
    Chain-wide consequences of transaction risks and their contractual solutions : managing interdependencies in differentiated agri-food supply chains

    Agri-food supply chains are characterized by strong interdependencies between the different stages. These interdependencies may lead to risk-spillovers, as when a downstream company is exposed to risks resulting from activities further upstream in the supply chain. For example, a change in the formula used to calculate the price in a farmer-processor transaction, may reduce incentives for farmers to produce high quality products. This can increase the risks that low quality products are exchanged in the processor-retailer transaction. The present thesis has examined the challenges which companies face in managing such interdependencies and associated transaction risks.More specifically, it has examined: (1), how risks arise in the supply chain as a result of the interdependencies between the various transactions making up the supply chain; and (2), what types of governance solutions are suitable for supply chain companies to implement in order to reduce or eliminate their exposure to these risks. Mainly economic risks resulting from conflicts of interests between the supply chain companies have been considered. Both a theoretical and an empirical approach have been used in the thesis. The theoretical approach is largely grounded within Transaction Cost Economic (TCE) literature. Empirical research has been conducted in a specific sub-section of the agri-food sector: the pork meat industry. Transactions have been examined between the companies operating in pork supply chains in various EU countries as well as in Brazil. Based on the analyses presented in the four studies of the thesis, various types of strategies have been identified which managers can use to minimize, alter, transfer or share their exposure to risk in the supply chain. These strategies include: (1), the use of specific provisions in contracts with suppliers or buyers (e.g., to fix prices or not); (2), the balancing of supply and demand side contract provisions; (3), the use of risk pooling vehicles, like jointly managed quality management systems or collective brands. Furthermore, the conditions under which these strategies should be employed have been identified. Compared to previous research, this thesis discusses more detailed strategies and considers the consequences of their use for the whole supply chain.
    Risky encounters : institutions and interventions in response to recurrent disasters and conflict

    The thesis focuses on local level responses to recurrent small disasters and conflict in Afghanistan, Indonesia and the Philippines. It critically reflects on Community-Based Disaster Risk Reduction (CBDRR) approaches to understand the gap between CBDRR policy and actual outcomes. It considers the multi-level institutions through with meaning and implementation of CBDRR policy are negotiated and transformed, from the conceptual policy design stage until the arena where decisions on risk solutions and resource allocation are made. Disasters and conflict are both understood as the product of a cumulative set of institutional arrangements and policy decisions over a long period of time. Vice versa, disasters and conflict affect institutional arrangements and re-order power relations. Interventions like CBDRR are not isolated, distinct entities, but are very much embedded in a context of particular institutional arrangements, which constrain or enable local actors to advance their risk-solutions. Through CBDRR interventions actors defend and mobilize around CBDRR practices that are meaningful to them, or resist institutions and practices that carry meanings they find disagreeable. This results in the manifold manifestations of CBDRR practices and outcomes. The research concludes that there is no such thing as the CBDRR approach. Instead, there are different processes through which local NGOs, civil society organizations, funding agencies and government agencies arrive at a specific framing of local realities and their responses in the context they live and work. These are related to their histories, current state - civil society relationships, and their mandate on how they legitimize their interventions. These actors either underscore the politics of their interventions or rather de-politicize them. From the experiences of this research it is plausible to conclude that when one ignores to view CBDRR interventions in a political and institutional manner, the out­comes of the interventions are likely to reproduce the status quo and are not supporting the vulnerable populations. The implication for humanitarian aid agencies is to include an institutional and political analysis in risk and vulnerability assessments to explain people’ vulnerability. This is crucial for strategizing actions and to engage in the political arena of disaster risk reduction with the aim to create safe and resilient communities. Rather than simply aiming for isolated village-level project objectives, CBDRR interventions have to think ahead of results to be achieved at district and even national level.
