Over the past 20 years, water quality in Indonesia has deteriorated due to an increase of water pollution. Research and analysis is needed to identify pollution sources and assess contamination in Indonesian water resources. Water quality management is not yet sufficiently integrated in river basin management in Indonesia, which mainly focuses on water quantity. Women are comparatively highly impacted by failing water resources management, but theirinvolvement in decision making processes is limited. Water quality deterioration continues to increase socio-economic inequality, as it are the most poor communities who live on and along the river. The uneven water quality related disease burden in Brantas River Basin widens the socio-economic gap between societal groups. In the Brantas region, cooperation and intention between stakeholders to tackle these issues is growing, but is fragile as well due to overlapping institutional mandates, poor status of water quality monitoring networks, and limited commitment of industries to treat their waste water streams. The existing group of Indonesian change makers will be supported by this project. Three Indonesian and three Dutch organisations have teamed up to support negotiation platforms in order to deal with institutional challenges, to increase water quality monitoring capacity, to build an enabling environment facilitating sustainable industrial change, and to develop an enabling environment in support of community concerns and civil society initiatives. The project builds on integrated water quality monitoring and modelling within a framework of social learning. The strong consortium will be able to build links with civil society groups (including women, farmer and fisher unions) in close cooperation with local, regional and national Indonesian governmentinstitutions to clean the Brantas river and secure income and health for East Java’s population, in particular the most vulnerable groups.

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.

In de binnenstad van Amsterdam wordt door infrastructuurproblematiek en het drukke verkeer de problematiek van bedrijfsafvalinzameling nog meer uitvergroot, naast dat de gemeente uitgesproken ambities heeft voor emissievrije stadslogistiek en de ontwikkeling van de circulaire economie. Daarom onderzoekt de gemeente met partners die actief zijn in afvalinzameling hoe gescheiden afvalstromen collectiever, kleinschaliger en frequenter ingezameld kunnen worden en met behulp van emissievrije, elektrisch aangedreven en lichtgewicht logistieke oplossingen wordt onderzocht. Één van de pilots betreft bedrijfsafvalinzameling over water in het wallengebied en is gerealiseerd door gemeente Amsterdam afdeling bedrijfsafval, afvalverwerker Renewi, logistiek bedrijf ZOEV City en sociaal leer-en werkbedrijf Pantar. Het restafval van een aantal bedrijven wordt door kleine elektrische voertuigen lokaal ingezameld en met een stuwboot naar de verwerker gebracht in plaats van inzameling door de gebruikelijke dieselvuilniswagen.In dit project onderzochten we hoe we een gezamenlijk ontwikkeld businessmodel voor deze nieuwe wijze van inzamelen in de case rendabel kan zijn voor de stakeholders. En we onderzochte hoe het bij kan dragen aan emissievrije logistiek, minder verkeersdruk, leefbaarheid in de omgeving, minder onderhoud aan de kademuren en een verbeterde afvalscheiding voor hergebruik in de circulaire economie. Het rapport laat zien hoe open collaborative business modelling, gecombineerd met impactmetingen kan helpen bij het ontwikkelen van oplossingrichtingen voor nieuwe circulaire samenwerkingsverbanden.

Fresh water systems are rapidly changing and water quality is deteriorating as a result of climate change. Aquatic drones can help us understand these changes - which will be key to tackling water-related challenges ahead.The ideas presented in this article aim to inspire adaptation action – they are the views of the author and do not necessarily reflect those of the Global Center on Adaptation.

This article reviews direct freshwater consumption in tourism from both quantitative and qualitative viewpoints to assess the current water demand of the tourism sector and to identify current and future management challenges. The article concludes that even though tourism increases global water consumption, direct tourism-related water use is considerably less than 1% of global consumption, and will not become significant even if the sector continues to grow at anticipated rates of around 4% per year (international tourist arrivals). The situation differs at the regional level because tourism concentrates traveller flows in time and space, and often-in dry destinations where water resources are limited. Furthermore, the understanding of tourism's indirect water requirements, including the production of food, building materials and energy, remains inadequately understood, but is likely to be more substantial than direct water use. The article concludes that with expected changes in global precipitation patterns due to climate change, it is advisable in particular for already water scarce destinations to engage in proactive water management. Recommendations for managing tourism's water footprint are made.

Inland surface water systems are characterized by constant variations in time and space. The increased pressure, of natural or anthropic origin, as a consequence of climate change, population growth and urban development accentuate these changes. Effective water management is key to achieve European waterquality and ecological goals. This is only possible with accurate and extensive knowledge of water systems.The collection of data using platforms such as underwater, water surface or aerial drones is gradually becoming more common and appraised. However, these are not yet standard practice in watermanagement. This work addresses the receptivity of water managers in the Netherlands towards underwater drone technology:· Listing and testing of suitable applications;· Comparison between data requirements of water managers (e.g. legislation) and data thatunderwater drones can provide;· Identification of features should R&D projects focus to increase the interest of the water sector.

Stadsontwerpers werken graag met water. Een van de voordelen zou zijn dat waterelementen hitte in de stad verminderen en de gevoelstemperatuur op straat verlagen. Maar hoe verkoelend is stedelijk water nu echt? Volgensverschillende studies is een verkoelend effect van watervormen zoals vijvers, grachten en sloten nauwelijks merkbaar of zelfs afwezig.
