Klimaat en waterbeheer
De opwarming van de aarde heeft mogelijk grote gevolgen, die voor een deel moeilijk te voorspellen zijn. Waarschijnlijk zien we in de toekomst meer weersextremen, terwijl meer dan de helft van de bevolking leeft in gebieden die kwetsbaar zijn voor klimaatverandering.
Effecten worden waargenomen in een stijgende zeespiegel. Dit komt deels doordat het zeewater uitzet naarmate het opwarmt. De zeespiegel stijgt ook doordat de ijskappen smelten en – in mindere mate – doordat berggletsjers terugtrekken. Klimaatverandering heeft ook enorme consequenties voor eilanden en landen met lange, lage kustlijnen die niet de middelen hebben om zich te beschermen
De gevolgen van klimaatverandering zijn zichtbaar in o.a., verzilting, stijgende waterniveaus, droogte en verwoestijning, maar ook in stedelijke klimaten. Klimaatverandering heeft een diepgaande invloed op voedselproductie en gezondheid in de wereld.

Verkenning samensmelting watertools voor de landbouw
- Nederland beschikt over diverse tools voor duurzaam water- en bodemmanagement in de landbouw, zoals het BedrijfsBodem- en WaterPlan (BBWP), de BedrijfsWaterWijzer (BWW), en IMAP (Inzicht in Maatregelen tegen Afspoeling van middelen vanaf Percelen). Deze tools ondersteunen melkvee- en akkerbouwbedrijven bij praktisch waterbeheer. Het integreren van deze tools kan voordelen opleveren door kennisversnippering te voorkomen. Op verzoek van het Ministerie van I&W onderzoeken de makers daarom de mogelijkheid tot samenvoeging. Hierbij wordt nadrukkelijk rekening gehouden met de wensen van gebruikers en belanghebbenden. -
Minder droogteschade door onderzoek naar duurzame innovaties in Friese zandgebieden
- Nederland heeft de afgelopen jaren steeds vaker te maken gehad met hete en droge zomers, waarbij de grondwatervoorraad onder druk kwam te staan met gewasschade en verdroging van natuur tot gevolg. In de laatste zes jaar hebben tientallen Friese agrariërs samen met regionale stakeholders vooruitgang geboekt in het vasthouden van water. Dit leidt tot een hogere grondwaterstand in de zomer en minder droogteschade aan gewassen en natuur. Bij een meer grootschalige aanpak op gebiedsniveau wordt de grondwaterstand in de zomer zelfs structureel verhoogd. -
Future ecosystems become increasingly thirsty due to climate change
- A new study shows that future ecosystem functions will be increasingly dependent on water availability. Using a suite of simulations from state-of-the-art climate models, several “hot spot regions” are found, where ecosystems are strongly affected by increasing water limitation. For example in Central Europe, the Amazon and the western part of Russia. These ecosystems become less healthy and productive in the future. Pinpointing such regions is essential: Healthy ecosystems are vital for human life, as they provide several key services, such as food and water security, sequestration of carbon dioxide (CO2) and evaporative cooling. -
How does forest restoration affect water cycles?
- Tree restoration is an effective way to store atmospheric carbon and mitigate climate change. Many initiatives exist to increase global tree cover. However, the effects of these initiatives on water resources are still poorly understood. Locally, tree restoration will enhance evaporation. But impacts on precipitation reach far beyond country or even continent level: tree restoration in the Amazon can, for example, affect rainfall in Europe and Eastern Asia. A new study led by Wageningen University & Research has calculated the impact of large-scale tree restoration on water fluxes and water availability globally.

EU Waterrichtlijnen
- In dit project wordt onderzoek uitgevoerd naar belasting van het oppervlaktewater met nutriënten en met name fosfaat uit de landbouw, met het oog op het realiseren van de doelstellingen uit de Europse Kaderrichtlijn water. -
The Round Landscape: Landscape-driven climate adaptation - nature-inclusive and circular
- Worldwide, there is growing attention for nature-based solutions as promising solutions for climate adaptation and mitigation. At the same time, the decline in biodiversity is receiving a great deal of attention. The aim of this project is to increase biodiversity and create conditions for climate-proof biodiversity by applying nature-based solutions for climate adaptation and mitigation in urban and rural areas. In nature-based solutions, we see natural processes as leading. -
Nature-based Solutions for Climate Resilient and Circular Food Systems
- Nature-based solutions are claimed to positively contribute to food security under climate change conditions. However, the knowledge underpinning this claim is fragmented and insufficiently existent. This project aimed to improve our understanding about nature-based solutions in the context of food systems at risks due to climate change. -
Deltas under Pressure
- Due to climate change and urban development, deltas are under pressure. Quick changes like climate change, salinization, water quality problems, floods and droughts, make adjustments in agricultural production necessary. An interdisciplinary research team of WUR work in an integrated manner on sustainable transition pathways in agriculture in deltas, with the ultimate goal to contribute to the sustainable development goal ‘Zero Hunger’ (SDG2). -
NKWK nuttig gebruik slib Eems-Dollard
- In the Knowledge and Innovation Agenda for Delta Technology 2018-2021, the sustainable use of estuaries, seas and oceans is one important theme. The challenge is to develop sustainable economic activities and their significance for spatial planning, safety, emissions and pollution. A number of new accents are described. One of these concerns: Cost-effective applications for silty sediment from the Ems estuary to initiate ecological recovery of the estuary and also stimulate the economy. This project gives substance to this new accent as part of Eco-engineering and Nature-based Solutions. -
Water Productivity Improvement in Practice (Water-PIP)

JCP: Joint Cooperation Programme Bangladesh – the Netherlands
- The Joint Cooperation Programme Bangladesh – the Netherlands (JCP) is a four year knowledge programme, working on Knowledge development for a prosperous delta. When in 2018 the Bangladesh Delta Plan 2100 got approved, this gave rise to a new type of research questions addressing the need to know more about what will happen in the future, and what way the country can to ready for that. -
Diagnosing drought for dealing with drought in 3D
- In April 2019 an interdisciplinary research project has started, coordinated by Wageningen University:Diagnosing drought for dealing with drought in 3D: Toolbox for increasing drought preparedness of actors in water and climate governance, starting from north-eastern Brazil.

Building with Nature
- Building with nature is a concept where nature is used to cope with climate change risks, such as floods, waves and sea level rise. It is also called 'nature-based solutions' or 'eco-engineering'. In this dossier you can find news, background information and results from scientists of Wageningen University & Research. -
The Netherlands in 2120
- Climate change, urbanisation, biodiversity, rising sea levels, extreme weather and increasing food production: these are just a few of the factors that help shape the spatial planning of the Netherlands. There appears to be a need to look to the future. With these factors in mind, what will the Netherlands look like a century from now? Wageningen University & Research has drafted a vision on what it believes a future-proof Netherlands could look like in 2120. -
Flooding
