What is it?
Rotterdam Climate Proof, The Rotterdam approach of the water management and climate adaptation challenge.
Issue – Our climate is changing. The consequences of climate change will be felt also in Rotterdam. Rain showers are growing heavier as it is, presenting the city with the challenge of excess water or flooding. In the long run, our low-lying delta city will also be confronted with rising sea levels and exceptionally high or low river levels and flows. Furthermore, the temperature in the city will rise, and heat stress will affect increasing numbers of people.
In order to confront the challenge of climate change as an opportunity rather than a threat, the City of Rotterdam has set up the Rotterdam Climate Proof programme. Rotterdam Climate Proof will make Rotterdam climate change resilient by 2025. Permanent protection and accessibility of the Rotterdam region are key elements. The central focus of the programme is to create extra opportunities to make Rotterdam a more attractive city in which to live, work, relax – and invest.
Trendsetting research, innovative knowledge development and a dynamic and decisive implementation of the suggested measures will result in strong economic incentives. Collaborating with prominent partners, Rotterdam will become an important innovative water knowledge city in the world, and an inspiring example to other delta cities.
How does it work?
Goals and Objectives – Rotterdam Climate Proof will make Rotterdam fully climate proof by 2025. Responding to climate change will enable us to keep the city safe, accessible, and attractive, now as well as in the future. This will benefit both the people who live and work here, and the businesses and corporations established in the area. This substantial ambition will be realized on the basis of three guiding principles:
- Rotterdam will develop into and present itself on a national and international level as a leading centre for water knowledge and climate change expertise.
- Investments in climate solutions will enhance the attractiveness of the city and port for residents, companies, and knowledge institutes.
- Innovations and knowledge are developed, implemented, and marketed as an export product.
Implementation – The Rotterdam Approach
Climate adaptation and spatial development are inextricably intertwined in Rotterdam. This approach allows urban planners to create designs that effectively address the issue of climate change. At the same time, the necessity to invest in climate adaptation will create and sustain the momentum needed to enhance the city’s attractiveness.
Adaptation to climate change is more than just a necessity for Rotterdam. Perhaps even more importantly, it offers an economic opportunity. This approach is characteristic of Rotterdam Climate Proof. Gaining knowledge and experience fast in combining water management and spatial planning will allow the corporate sector to build a powerful competitive advantage.
Rotterdam’s Climate Adaptation Strategy (RAS)
Climate change resilience in Rotterdam will first and foremost involve sustainable protection against flooding in the areas inside and outside the levees. In addition to flood management, the city will have to focus on other ways to prepare for the consequences of climate change as well, such as higher incidence rates of heat waves, increased heavy precipitation, groundwater salinization, changing options for transport by water, and increased volatility of groundwater levels. What is essential for an adaptive strategy is that it is implemented proactively and that it can be adjusted to changing circumstances. The Rotterdam Climate Adaptation Strategy (RAS) clearly defines the measures that can be taken to climate proof the area.
The implementation of this proactive strategy requires knowledge and tools. In concrete terms, RAS consists of four clusters:
- The trajectory: Which specific objectives and milestones can we define on the road to climate change resilience? This involves both a substantive definition and planning. Subprojects: developing a climate atlas and a route planner.
- The specific activities: Keeping in mind the trajectory and the milestones to be attained, the question can be answered as to what project managers can do specifically to climate proof their areas. Subproject: developing a climate tool box.
- The procedure: This involves embedding climate adaptation into current work processes. Eventually, the issue of climate proofing will have to be included in the early phases of all spatial planning, policy-making, implementation and management. Subproject: incorporating climate adaptation.
- The state of affairs: What is the current state of affairs for the projects of Rotterdam Climate Proof; which interim objectives have been achieved so far? How can we make them manifest? Subprojects: monitoring climate adaptation, and developing a barometer.
Rotterdam Climate Proof nourishes high ambitions. Their realization requires decisiveness, knowledge development, space to test and experiment, and new partnerships and alliances. For this purpose, Rotterdam has decided to adopt a clever way of combining policy and implementation, considerations and execution. Innovative solutions will enhance the safety and the quality of life in the city, while at the same time offering substantial economic potential for the entire region. Rotterdam thus becomes an inspiring example to other delta cities.
1. Knowledge: Rotterdam is developing into a leading national and international water knowledge and climate city.
Trendsetting research in the area of theoretical and applied delta technology enables Rotterdam to create the basis for groundbreaking innovations and international collaboration. Within the national research programme entitled ‘Knowledge for Climate’, Rotterdam has been named a hotspot in this field. In concrete terms, this means that a fund of over 5 million euros is available for the 50% co-financing of research efforts. Accordingly, most of the knowledge projects are included in this programme.
Knowledge development also takes place through knowledge exchange. For this reason, Rotterdam has set up the international knowledge network called ‘Connecting Delta Cities’. In addition, Rotterdam cooperates intensively with Rotterdam University (water management) and Erasmus University Rotterdam (EUR). New educational programmes focused on water management and delta issues are currently being developed, and students are given a chance to work for Rotterdam Climate Proof. Whereas the study programmes in Rotterdam focus mainly on applied knowledge, the cluster with Delft University of Technology predominantly addresses theoretical knowledge. The province of Zeeland serves as a testing ground in this respect where natural elements are used in construction work. A powerful region is thus created, where knowledge development is linked with the application of water management and delta technology, allowing the results to be marketed through the knowledge and innovation cluster as part of Clean Tech Delta.
2. Actions: Rotterdam is developing into a global testing ground in the field of delta technology and adaptive building.
Investing in a climate proof city contributes to the realization of a safe, healthy, and attractive living environment and a strong economy for the residential and business communities. Innovations and knowledge are developed and applied for use in Rotterdam. Especially the Stadshavens district will be the recipient of substantial investments, for instance in terms of adaptive building and floating constructions (such as the floating pavilion), and the National Water Centre. This will help Stadshavens to become the showcase of Rotterdam for ‘urban delta technology’.
3. Positioning: Rotterdam is an inspiring example to delta cities around the world.
Rotterdam positions itself as a delta city with a world port that approaches future climate change in an unassuming, safe and innovative manner. Not only on a local level but also on a national and international level, Rotterdam projects an image of innovation, reliability, and decisiveness. In 2010, Rotterdam will be represented at the World Expo to show the world how this metropolis manages to keep the city and port protected against flooding, despite climate change. Establishing international knowledge agreements and partnerships, Rotterdam takes up a prominent position among the leaders in the field. These leaders in the international field of water management and delta issues will attend the conference entitled ‘Deltas in Times of Climate Change’, which will take place in Rotterdam between 29 September and 2 October 2010.

Results and Evaluation
Changes effected and results evaluated are part of the Rotterdam Adaptation Strategy and are secured in the following instruments:
This involves an outline of the region-specific impact of climate change, scenarios, and the measures that have already been implemented. Region-specific climate change predictions will be laid down in a climate atlas. The final design will be developed in 2010, based on the input of the users of the information.
The climate barometer is a communication-oriented monitoring tool that will provide insight into the level of climate change resilience of the city of Rotterdam. In 2010, we will focus on translating the concept into a mature instrument.
Physical measures that are taken are monitored, and their effects on the speed and scope of the expected climate change are recorded. In addition, this allows us to assess the positive spin-off for the objectives of Rotterdam Climate Proof, such as enhancing the attractiveness of the city and adding economic value.?Subsequently, we will create a comprehensive overview of the progress of the Rotterdam Climate Proof projects and their implementation. To get a good impression of the progress and the correlation between all programme elements, we will assess whether it is useful and possible to develop a dashboard for this purpose. This is also part of the Smart Delta City Concept.
Defining the milestones, actions and options for each theme in the course of time, the route planner is the backbone of Rotterdam’s adaptation strategy. The road to climate change resilience may vary for each theme, and they may be interdependent. In 2010, this route planner will be elaborated in further detail for all of the themes, including a description of their interdependence.
Climate tool box:
This involves area-specific adaptation options in support of a proper balance in measures to be taken. In 2009, climate adaptation was incorporated in the Stadshavens case. In 2010, the emphasis will be on the implementation of the methodology in several areas.
Climate change resilience will be embedded in spatial planning, area development, implementation and policy guidelines. Existing instruments and methods will be tested for possible alignment (e.g., Structural Concept, Water Test, EIA, Rotterdam Style). Proper organizational incorporation within ‘Rotterdam corporate’ is crucial in this respect, as is a clear representation of all of the consequences, opportunities, instruments, and expenses involved. Finally, research will be conducted into the question as to whether it would be effective to provide assurance for the climate ambitions and objectives in the form of a policy framework.

What is it?
Lake Houston is an 11,000 acre water body used by the City of Houston as a drinking water source for over 2 million residents. Generally the lake has good water quality, however blue-green algal proliferation and deficient oxygen at lower depths has caused significant taste and odour issues in the drinking water.
How does it work?
A Laminar flow hypolimnetic circulator (Solar Bee) is a floating solar-powered reservoir circulator. It creates a 4-6 foot diameter column of rising water below the machine and spreads this water gently across the top of the reservoir in a long distance flow pattern, affecting up to 35 surface acres. Depending on the model, the Solar Bee is 10 - 17 feet in diameter with flow rates between 1,250 - 10,000 gallons per minute.
Additional projects with Texas Parks to expand biological shifts and other drinking water sources for human consumption.
Circulation of stagnant water bodies can be immediately beneficial to local ecosystems used as local drinking water sources. Solar Bees are very cost effective and can be modified for use in a wide range of varying ecosystems.Download PDF
