Healthy gestational weight gain (GWG) is associated with better pregnancy outcomes and with improved health in the later lives of women and babies. In this thesis the author describes the process of developing an intervention to help pregnant women reach a healthy GWG. The need for this intervention was derived from discussions with midwives, working in primary care in the Netherlands. In this introduction, the author describes the background of the larger project “Promoting Health Pregnancy”, of which this study is a part (1.2), the problem of unhealthy GWG (1.3-1.6) and offers a brief introduction to the theoretical framework of the study and to the subsequent chapters (1.7-1.9).
The growing appetite of cities is one of the greatest future challenges. There is no set menu for meeting this appetite, but a trend is observed in which city authorities focus on region-based food provision. Regionalism is motivated by the importance of increased self-reliance. Besides, regional food systems, are associated with more sustainable production and reduced carbon footprints, the reconnection of consumers with production, and the increased uptake of whole foods in urban diets. However, the question remains to what extend region based food systems may become self-reliant? How may they contribute to improved sustainability and healthy lifestyles? With the Dutch city of Almere as a case in point this paper provides a food flow data-based analysis of the opportunities and limitations of regional based food system approaches. The paper sets off with defining the concepts of sustainable self-reliance and regionalism. Next, it describes the methodology of measuring and mapping the actual food flows. We combined secondary, publicly available, with primary quantitative and qualitative datasets, involving regional businesses, urban policymakers, and residents. Our study uncovers the coinciding disconnect and interconnectedness of local, regional and global food systems. The regional scale offers opportunities for tackling many food related challenges, however, sustainable urban food security demands connections beyond the regional sphere and beyond the food domain. To assess the effects of the policy options available at the local and regional level, a solid evidence base is essential. This paper advances the development of evidence-based methodologies to monitor and inform food system policies.

The seaweed aquaculture sector, aimed at cultivation of macroalgal biomass to be converted into commercial applications, can be placed within a sustainable and circular economy framework. This bio-based sector has the potential to aid the European Union meet multiple EU Bioeconomy Strategy, EU Green Deal and Blue Growth Strategy objectives. Seaweeds play a crucial ecological role within the marine environment and provide several ecosystem services, from the take up of excess nutrients from surrounding seawater to oxygen production and potentially carbon sequestration. Sea lettuce, Ulva spp., is a green seaweed, growing wild in the Atlantic Ocean and North Sea. Sea lettuce has a high nutritional value and is a promising source for food, animal feed, cosmetics and more. Sea lettuce, when produced in controlled conditions like aquaculture, can supplement our diet with healthy and safe proteins, fibres and vitamins. However, at this moment, Sea lettuce is hardly exploited as resource because of its unfamiliarity but also lack of knowledge about its growth cycle, its interaction with microbiota and eventually, possible applications. Even, it is unknown which Ulva species are available for aquaculture (algaculture) and how these species can contribute to a sustainable aquaculture biomass production. The AQULVA project aims to investigate which Ulva species are available in the North Sea and Wadden Sea which can be utilised in onshore aquaculture production. Modern genomic, microbiomic and metabolomic profiling techniques alongside ecophysiological production research must reveal suitable Ulva selections with high nutritional value for sustainable onshore biomass production. Selected Ulva spp lines will be used for production of healthy and safe foods, anti-aging cosmetics and added value animal feed supplements for dairy farming. This applied research is in cooperation with a network of SME’s, Research Institutes and Universities of Applied Science and is liaised with EU initiatives like the EU-COST action “SeaWheat”.
In line with the ‘Natuur- en milieubeleidsplan Caribisch Nederland 2020-2030 (NMBP)’ the consortium intends with this research proposal to contribute to a prosperous society with a resilient population and healthy natural environment. The Caribbean Netherlands are dealing with a situation where imported vegetables and fruits are mostly imported and hardly affordable. This leads to consuming unhealthy food and high obesities rates as a consequence. A lack of good agricultural practices with regard to water-smart and nature inclusive agriculture, as well as limited coping capacities to deal with hazards and climate change, results in very limited local production and interest. Initiatives that focused only on agrotechnological solutions for food resilient futures turned out to be ineffective due to a lack of local ownership, which jeopardizes sustainability. Moreover, the ‘green’ and ‘blue’ domains are not seen as attractive career perspectives among youth, hampering a bright future for those domains. The aim of this research is to contribute to water-smart and nature inclusive food resilience embedded in a local participatory perspective in the Caribbean Netherlands. To address the above challenges, a living lab approach is adopted, where youth will be trained as (co)-facilitators (WP1) who will contribute to a participatory envisioning process and an articulation of food resilient futures (WP2). Finally, based on the envisioning process local stakeholders will select and implement experiments for food resilient futures followed by dissemination of results among key stakeholders as well as children and youth at the BES islands (WP3). This project strategy will lead to a network of a living lab where professionals and youth work together on food resilient futures. Training manuals and the results of experiments with regard to water and food system alternatives will be used actively to encourage youth to be involved in sustainable agriculture and consumption.
Een groeiende groep senioren woont steeds langer zelfstandig thuis en het is bekend dat bij deze doelgroep aandacht voor een gezond (eiwitrijk) voedingspatroon belangrijk is. Het HAS lectoraat Voeding & Gezondheid van Dr. A. Roodenburg richt zich met het onderzoeksprogramma ‘Voeding voor senioren’ op het voedingsgebruik en –gedrag van deze doelgroep. In een aantal reeds lopende projecten wordt onderzoek gedaan naar het verhogen van kennis en bewustzijn over het belang van hogere eiwitconsumptie bij deze doelgroep. Het huidige voorstel bouwt hierop voort en richt zich met name op het gedrag van senioren (aanschaf van eiwitrijke producten) en gaat onderzoeken welke factoren ten aanzien van kennis, houding en sociale druk (Theory of Planned Behavior) hierbij een rol spelen. Deze informatie kan worden ingezet om senioren te sturen op de diverse aspecten om hen zo te verleiden tot de gewenste actie (= verhogen eiwit-inname). Uitkomsten van dit onderzoek geven richting voor productontwikkeling, marketing en communicatie. Voor een sterke verbinding van onderzoek en onderwijs wordt dit onderzoek uitgevoerd door de postdoc (Dr. J Linschooten) en met diverse studententeams onder begeleiding van de postdoc. De nieuw verworven kennis zal terugkomen in het curriculum van diverse HAS opleidingen zoals Voedingsmiddelentechnologie, Food Innovation en de minor ‘Towards a Healthy Society’, als ook in een masterclass voor externe partners (bedrijven/ publieke instellingen) om bij te dragen aan een betere afstemming van het productaanbod op deze doelgroep. Het postdoc programma zal ook ruimte bieden voor een versterking van de algemene leerlijn ‘Onderzoeksvaardigheden’ om docenten en studenten van eerder genoemde opleidingen beter te begeleiden bij de ontwikkeling van deze competentie.
