Hotspot The Haaglanden region

The Haaglanden region is a unique area. The region includes the conurbation of The Hague and a high concentration of greenhouse cultivation. The limits of urban expansion have almost been reached in the Haaglanden region. In order to match economic and population growth to this fact, authorities in the Haaglanden region have decided to implement a restructuring and compaction of existing urban and greenhouse areas in the coming years. This will be further complicated by the large demand for space for water. This demand is related to the impacts of climate change, which have already started to take effect: extreme rainstorms have already been causing flooding and damage several times.

The scale of the water accommodation issues combined with the present and future urban and economic functions required an integrated regional approach. After all, the 'everyone on his own' approach no longer worked. All parties in the region, governmental and commercial bodies, saw the urgency of the issue and wished to cooperate in gaining more experience with alternative ways of solving water problems. The public authorities in Haaglanden drew up the Regional Administrative Agreement on Water in February 2006, in which agreements were signed concerning an innovative and collective approach. The parties involved worked on a number of representative pilot projects (in urban, greenhouse cultivation and grassland areas), in which short term investment decisions concerning the water issues were linked to long term climate adaptation.

Objective
The objective was to develop concrete adaptation strategies for climate change (in the form of precipitation extremes in particular) for a number of pilot projects in the highly urbanised environment of Haaglanden.

The climate knowledge issues were identified based on the following themes:

    1. Water storage and drainage capacity in the case of extreme precipitation in the urban environment
    2. The coastal position and the water security aspect
    3. The future of greenhouse cultivation in a changing climate
    4. The consequences of climatic effects for economic investments and the living environment

HSHL01A: Climate in spatial decision making
The consequences of climate change on water management aren’t taken into account sufficiently when choosing locations for new functions or redevelopment of current locations. A good assessment is of importance to prevent high costs in future water management. This project developed a dialogue supporting assessment framework. This framework will ensure that... read more

HSHL02: Future of the fen meadow area
The open area between Haaglanden and Rijnmond is an important area for recreation, with people coming from the surrounding urbanized areas. The available rural space is under increasing pressure. It has been designated as a metropolitan park in the Randstad 2040 plans. Climate change also affects this fen meadow area by an increase of the shortage as well as excess of water... read more

HSHL05/HSRR04: Region specific climate information for Haaglanden and Rotterdam
The goal of this project was to make climate data and information about the current and future climate specific for the regions Haaglanden and Rotterdam. The focus was on climate effects which concerned users in the area. Potentially affected users have been identified, as well as their dependency on climate... read more

HSHL06/HSHL12: Broad, region specific reconnaissance of effects of climate change in relation to future scenarios and trends
Changes in climate and society require an adaptation in the current spatial planning process in Haaglanden. In this project, research was done on area specific effects of climate change in relation to the expected socio economic developments. The goal was to be... read more

HSHL08: Demonstration project multifunctional land use for water storage in the greenhouse sector
In this polder in the urban area of Haaglanden and the municipality of Westland innovative solutions were sought for realising water retention. The project joined in on current spatial planning processes and used a concept of closing the water cycle, the 4B-concept, where industrial waste water is purified to irrigation water... read more

HSHL3.3: 3Di water management applicable for end users
3Di is an instrument to develop and evaluate adaptation strategies. The water authority and municipalities of the densely populated Hotspot Haaglanden need new methods and smart solutions to deal with limited land space, long legal procedures and high investments, which are a problem for the current... read more
