Climate change and urbanization will increase the frequency and magnitude of urban flooding and water quality problems in many regions of the world. In coastal and delta areas like The Netherlands and the Philippines, where urbanization is often high, there has been an increase in the adoption of sustainable urban drainage systems (SUDS). SUDS are installed around the world with the expectation to reduce urban flooding and reduce the pollution impact on receiving waters. Most cities in Asia are starting to implement SUDS as their strategy to make their cities sustainable and resilient.The combination of SUDS with appropriate wastewater treatment and management systems have the potential to be multifunctional in alleviating flood run-off, improving water quality, alleviating heat stress and as a source for reusing the stormwater and wastewater.Since the earliest SUDS are implemented in Europe decades ago it is advised to use the lessons learnt in this process. International knowledge exchange is promoted in projects as IWASTO where several organisations from the Philippines and The Netherlands join forces on a specific region as the Pateros riverin Manila with the aim to minimise the pollution impact on this receiving water. The first findings of this project related to storm water and wastewater management are presented in this paper. In this stage of the project high level support models that map the challenges in the city (such as flooding and heatstress) arevaluable tools for implementing cost effective sustainable drainage for improving water quality.

The need of an adaptive sustainable solution for the increased land scarcity, growing urbanization, climate change and flood risks resulted in the concept of the floating urbanization. In The Netherlands this new type of housing attracted the interest of local authorities, municipalities and water boards. Moreover, plans to incorporate floating houses in the urban planning have already been developed. However, the knowledge gap regarding the potential effect on the water quality halts the further development of the floating houses. This paper shows the results of a water quality measurement campaign, as part of the national program “Knowledge for climate”, at a small floating houses project in Delft and serves as a case study for addressing the environmental-ecological knowledge gap on this topic.

Antibiotics are a factor in developing antibiotic resistance in the environment. Outbreaks due to pathogens and resistant bacteria are an emerging issue in this decade. Resistance of Escherichia coli to two groups of antibiotics has been revised recently by the World Health Organization (WHO). These data showed that bacteria have already developed resistance to third and fourth group of antibiotics. The WHO report on surveillance and antibiotics consumption evaluation showed that antibiotic consumption varies in EU countries. Outbreaks have increased in parallel to these data depending on country, season, sex, and age group. This chapter revises the routes of spreading and surveillance of E. coli. There is a particular focus on water sources including hospitals, urban wastewater treatment plants (UWTPs), diffuse sources, and water reuse. Extensively revised data are given on the control techniques by biological and advanced processes. The emerging issue of gene transfer control in parallel to the control of bacteria is expressed. A detailed literature survey of emerging technologies of photocatalysis and nanoparticles is given.

Inleiding en praktijkvraag De groeiende wereldbevolking gecombineerd met de klimaatverandering zorgt voor een de noodzaak tot een duurzame voedselvoorziening (KIA missie Landbouw, voedsel & water). Een significante reductie van gewasbestrijdingsmiddelen is daarbinnen een belangrijke doelstelling. Robotica maakt als technologie motor van de precisielandbouw plant specifieke precisie-bestrijding mogelijk. Het projectconsortium onderzoekt een semiautonoom samenwerkend grond-luchtrobot platform voor de precisielandbouw. Projectdoelstelling De doelstelling van het project AGRobot Platform is dan ook: “Onderzoek de mogelijkheden van een semi-autonoom samenwerkend grond-lucht robotplatform voor de precisielandbouw”. De hoofddoelstelling wordt binnen dit project beantwoordt door de deliverables uit de volgende subdoelstellingen: 1. Case studie onderzoek naar de mogelijke voordelen van het grond-luchtrobotplatform 2. Onderzoek naar de benodigde technologieën voor een grond-luchtrobotplatform 3. Ontwikkelen van een eerste (mogelijk case-specifieke) demonstrator 4. Ontwikkelen van (nieuwe) samenwerkingsvormen. Vraagsturing & Netwerkvorming Riwo Engineering is een industriële automatiseeerder die met zijn grondrobots en control-besturingssytemen actief is in de veeteelt. DRONEXpert gebruikt hyperspectrale camera’s onder drones voor het bemeten van gewassen. Saxion mechatronica onderzoekt met de onderzoekslijn unmanned robotic systems hoe de nieuwste robotica technologieën systemen mogelijk maakt voor ongestructureerde omgevingen. De partners bezitten gezamenlijk een enorm netwerk (TValley, Space53, euRobotics) en klanten om via de case studies de kansen te achterhalen en te realiseren. Innovatie Nergens ter wereld is een samenwerkend grond-luchtrobot platform actief in de precisielandbouw. Voor OostNederland, met naast veel robotica kennis ook veel Agro-kennis, zal het project letterlijk de KIEM zijn voor nieuwe projecten waaruit de valorisatie kansen richting heel Europa gaan. Activiteitenplan & Projectorganisatie Het project wordt geleid door de lector Dr. Ir. D.A.Bekke en uitgevoerd door Abeje Mersha en Mark Reiling samen met het deelnemend MKB. Het project bestaat uit 4 werkpakketten die achtereenvolgens antwoordt geven op de gestelde subdoelstellingen. Aan elk werkpakket zijn deliverables gekoppeld.
Due to the existing pressure for a more rational use of the water, many public managers and industries have to re-think/adapt their processes towards a more circular approach. Such pressure is even more critical in the Rio Doce region, Minas Gerais, due to the large environmental accident occurred in 2015. Cenibra (pulp mill) is an example of such industries due to the fact that it is situated in the river basin and that it has a water demanding process. The current proposal is meant as an academic and engineering study to propose possible solutions to decrease the total water consumption of the mill and, thus, decrease the total stress on the Rio Doce basin. The work will be divided in three working packages, namely: (i) evaluation (modelling) of the mill process and water balance (ii) application and operation of a pilot scale wastewater treatment plant (iii) analysis of the impacts caused by the improvement of the process. The second work package will also be conducted (in parallel) with a lab scale setup in The Netherlands to allow fast adjustments and broaden evaluation of the setup/process performance. The actions will focus on reducing the mill total water consumption in 20%.
The postdoc candidate, Giuliana Scuderi, will strengthen the connection between the research group Biobased Buildings (BB), (collaboration between Avans University of Applied Sciences and HZ University of Applied Sciences (HZ), and the Civil Engineering bachelor programme (CE) of HZ. The proposed research aims at deepening the knowledge about the mechanical properties of biobased materials for the application in the structural and infrastructural sectors. The research is relevant for the professional field, which is looking for safe and sustainable alternatives to traditional building materials (such as lignin asphalt, biobased panels for bridge constructions, etc.). The study of the mechanical behaviour of traditional materials (such as concrete and steel) is already part of the CE curriculum, but the ambition of this postdoc is that also BB principles are applied and visible. Therefore, from the first year of the programme, the postdoc will develop a biobased material science line and will facilitate applied research experiences for students, in collaboration with engineering and architectural companies, material producers and governmental bodies. Consequently, a new generation of environmentally sensitive civil engineers could be trained, as the labour market requires. The subject is broad and relevant for the future of our built environment, with possible connections with other fields of study, such as Architecture, Engineering, Economics and Chemistry. The project is also relevant for the National Science Agenda (NWA), being a crossover between the routes “Materialen – Made in Holland” and “Circulaire economie en grondstoffenefficiëntie”. The final products will be ready-to-use guidelines for the applications of biobased materials, a portfolio of applications and examples, and a new continuous learning line about biobased material science within the CE curriculum. The postdoc will be mentored and supervised by the Lector of the research group and by the study programme coordinator. The personnel policy and job function series of HZ facilitates the development opportunity.
