The interaction between physical drivers from oceanographic, hydrological, and meteorological processes in coastal areas can result in compound flooding. Compound flood events, like Cyclone Idai and Hurricane Harvey, have revealed the devastating consequences of the co-occurrence of coastal and river floods. A number of studies have recently investigated the likelihood of compound flooding at the continental scale based on simulated variables of flood drivers, such as storm surge, precipitation, and river discharges. At the global scale, this has only been performed based on observations, thereby excluding a large extent of the global coastline. The purpose of this study is to fill this gap and identify regions with a high compound flooding potential from river discharge and storm surge extremes in river mouths globally. To do so, we use daily time series of river discharge and storm surge from state-of-the-art global models driven with consistent meteorological forcing from reanalysis datasets. We measure the compound flood potential by analysing both variables with respect to their timing, joint statistical dependence, and joint return period. Our analysis indicates many regions that deviate from statistical independence and could not be identified in previous global studies based on observations alone, such as Madagascar, northern Morocco, Vietnam, and Taiwan. We report possible causal mechanisms for the observed spatial patterns based on existing literature. Finally, we provide preliminary insights on the implications of the bivariate dependence behaviour on the flood hazard characterisation using Madagascar as a case study. Our global and local analyses show that the dependence structure between flood drivers can be complex and can significantly impact the joint probability of discharge and storm surge extremes. These emphasise the need to refine global flood risk assessments and emergency planning to account for these potential interactions.

To be able to ‘survive’ in a more and more globalising world, students of universities and universities of applied sciences must attain international competencies, in this study defined as respectively general personal, social competencies, intercultural competencies, a command of foreign languages and international academic and professional competencies. International competencies can be attained in different ways by students: internally (via foreign teachers and/or students) and/or externally (via internships and/or exchanges). The external attainment of competencies is far more successful when students are well prepared and when they receive proper supervision, both during and after their stay abroad. If this is not the case, students often tend to develop at a personal, social and (inter)cultural level, but significantly less at an academic and professional level (Stronkhorst, 2005). These students are also often unable to recognize and express which knowledge and skills they attained during their stay abroad (Orahood et al., 2004; CERI, 2008; Deardorff, 2009). With the preceding information as a starting point, the Social Work degree programme of Windesheim University of Applied Sciences in Zwolle started the minor ‘Social Work in Africa & Asia’ in the beginning of 2014. Students who participate firstly pass through a a six-week preparatory theoretical programma, followed by a three-month internship in Uganda or Vietnam. The minor concludes with a two-week postmortem programme. The practical component of the minor involves Eye4Africa, a Dutch internship supervision agency for internships in Uganda, Kenya and Vietnam. Eye4Africa arranges the internships, prepares the students for their stay abroad, both in the Netherlands and abroad, and then offers them support, coaching and intervision meetings. At the initiative of and in collaboration with Eye4Africa The Hague University of Applied Sciences carried out a qualitative study amongst eight female students of the Social Work degree programme of Windesheim University of Applied Sciences who followed the minor ‘Social Work in Africa & Asia’ during the academic year 2014-2015. The following was key to the research conducted: the question of the extent to which preparation for the Social Work in Africa & Asia minor at Windesheim University of Applied Sciences and the supervision that the Eye4Africa internship agency offers fourth-year Social Work students during their internships in Uganda in the autumn of 2014 had a positive impact on the attainment and further development of international competencies. The results have shown that the students found it very easy to recognise and express the knowledge and skills they gained during their internships. Secondly, the students mentioned clear professional, intercultural and personal, social growth. No growth or development in relation to academic competencies was observed in this study. However, this is not unusual, as the students were doing internships. Academic competencies are particularly attained when studying abroad, while professional competencies are particularly attained during internships (Hoven & Walenkamp, 2013; 2015). The main conclusion of this study is that the preparation and the supervision by Windesheim University of Applied Sciences and Eye4Africa within the framework of the minor ‘Social Work in Africa & Asia’ has aided students with regard to growth and the (further) development of international competencies. Some important short comments are that a relatively small, very one-sided sample has been interviewed and that there was no control group.
European Union’s vulnerability to climate change stretches far beyond its borders because many of its economic sectors, such as meat and dairy, use raw materials sourced from far afield. Cross-border climate vulnerability is a relatively new subject in scientific literature, while of high societal and economic relevance. We quantify these climate vulnerabilities with a focus on drought risk and assessed them for 2030, 2050, 2085 and for RCP 2.6 and 6.0 climate scenarios. Here we find that more than 44% of the EU agricultural imports will become highly vulnerable to drought in future because of climate change. The drought severity in production locations of the agricultural imports in 2050 will increase by 35% compared to current levels of drought severity. This is particularly valid for imports that originate from Brazil, Indonesia, Vietnam, Thailand, India and Turkey. At the same time, imports from Russia, Nigeria, Peru, Ecuador, Uganda and Kenya will be less vulnerable in future. We also report that the climate vulnerabilities of meat and dairy, chocolate (cocoa), coffee, palm oil-based food and cosmetic sectors mainly lie outside the EU borders rather than inside.

This project entails a feasibility study to assess the possibility of creating an open-access, community-based makerspace in the Vietnamese city of Can Tho. The aim of the project is to kickstart the community based circular economy by utilizing residual flows from the plastic catching process. Plastic catchers trap both plastic and biomass that will be converted into new products to strengthen both the local economy and providing Dutch SME-company Orange Star Solutions with the necessary raw materials to convert into produce. The project will make use of a plot of land bordering the Song Can Tho river. The owner proposed that the plot of land could be used in a way to generate income, preferable in a way that would show environmental awareness. This could be done by using the vast amounts of (in)organic waste that is littering the environment. The collection of the waste is mainly done by local waste pickers. The waste pickers, part of the informal economy, could unleash their full potential if there is a physical location where waste is upcycled and sold, circumventing the bury, burn or bale-and-export economy. The extracted plastic will be converted into pans, cups, pots and crockery. The biomass, predominantly water hyacinth, will serve as one of the ingredients for compost hence, reducing the reliance on chemical fertilizers.
Collaborative networks for sustainability are emerging rapidly to address urgent societal challenges. By bringing together organizations with different knowledge bases, resources and capabilities, collaborative networks enhance information exchange, knowledge sharing and learning opportunities to address these complex problems that cannot be solved by organizations individually. Nowhere is this more apparent than in the apparel sector, where examples of collaborative networks for sustainability are plenty, for example Sustainable Apparel Coalition, Zero Discharge Hazardous Chemicals, and the Fair Wear Foundation. Companies like C&A and H&M but also smaller players join these networks to take their social responsibility. Collaborative networks are unlike traditional forms of organizations; they are loosely structured collectives of different, often competing organizations, with dynamic membership and usually lack legal status. However, they do not emerge or organize on their own; they need network orchestrators who manage the network in terms of activities and participants. But network orchestrators face many challenges. They have to balance the interests of diverse companies and deal with tensions that often arise between them, like sharing their innovative knowledge. Orchestrators also have to “sell” the value of the network to potential new participants, who make decisions about which networks to join based on the benefits they expect to get from participating. Network orchestrators often do not know the best way to maintain engagement, commitment and enthusiasm or how to ensure knowledge and resource sharing, especially when competitors are involved. Furthermore, collaborative networks receive funding from grants or subsidies, creating financial uncertainty about its continuity. Raising financing from the private sector is difficult and network orchestrators compete more and more for resources. When networks dissolve or dysfunction (due to a lack of value creation and capture for participants, a lack of financing or a non-functioning business model), the collective value that has been created and accrued over time may be lost. This is problematic given that industrial transformations towards sustainability take many years and durable organizational forms are required to ensure ongoing support for this change. Network orchestration is a new profession. There are no guidelines, handbooks or good practices for how to perform this role, nor is there professional education or a professional association that represents network orchestrators. This is urgently needed as network orchestrators struggle with their role in governing networks so that they create and capture value for participants and ultimately ensure better network performance and survival. This project aims to foster the professionalization of the network orchestrator role by: (a) generating knowledge, developing and testing collaborative network governance models, facilitation tools and collaborative business modeling tools to enable network orchestrators to improve the performance of collaborative networks in terms of collective value creation (network level) and private value capture (network participant level) (b) organizing platform activities for network orchestrators to exchange ideas, best practices and learn from each other, thereby facilitating the formation of a professional identity, standards and community of network orchestrators.
Dit project is een haalbaarheidsstudie naar de benodigde eigenschappen van een flood early warning system in het stroomgebied van de Rode Rivier in noordwest Vietnam. In het project wordt zowel de gebiedskennis verzameld als een lokaal netwerk gevormd, zodanig dat een smart sensor system voor waterbeheer ingericht kan worden dat de lokale bevolking in staat stelt om tijdig te anticiperen op plotselinge overstromingen. Door extreme weersituaties die zich regelmatiger voor zullen doen zullen de effecten van overstromingen verergeren. Met name vanwege het zeer korte tijdsbestek waarbinnen overstromingen op kunnen treden, is het voor de bevolking noodzakelijk om zelfstandig hierop te kunnen anticiperen. Door de effecten van klimaatverandering en grootschalige ontbossing is het risico op overstromingen in de gehele regio sterk toegenomen. Daarom zal ook gekeken worden naar de mogelijkheden van opschaling van voornoemd systeem. In dit project wordt ook de basis gelegd voor een nieuw samenwerkingsverband tussen het HAN/VHL lectoraat Sustainable River Management, Eijkelkamp Soil & Water, Prins Land, Water & Food Consult en het World Agroforestry Centre (ICRAF). Deze partners hebben de gedeelde ambitie om een pilot project te realiseren voor een early warning systeem, waarmee op basis van real-time empirische data over neerslag en rivierafvoer automatisch een waarschuwingssignaal naar mobiele telefoons in een bepaald gebied gegenereerd kan worden, zodat de bevolking tijdig maatregelen kan nemen voor evacuatie en/of om ernstige schade te beperken bij verhoogd risico op zogenaamde 'flash floods'. Deze ambitie zal gezamenlijk uitgewerkt worden in een voorstel voor een pilotproject onder bijv. de Partners voor Water regeling.
