Proeftuin Erasmusveld
Short description of the intervention
'Proeftuin Erasmusveld' is a new and sustainable urban residential area in The Hague. It will be a new nature-inclusive, energy-efficient, car-free neighbourhood that is created for plants, animals and people promoting healthy living (1). As of November 2020, The building of the neighbourhood with its unique houses and buildings is still in progress (1).

Currently, the area is an 'experimental area' for all kinds of sustainability initiatives that may be used for the realization of the neighbourhood, including self-sufficient 'tiny houses' and urban farmland (1,2). The ambition for Erasmusveld is to become a leading sustainable neighbourhood with a sustainable water system, the use of sustainable energy and a vegetable garden with high connectedness between citizens (4).

Present stage of the intervention
Please specify "other" stage of the intervention
Parts of the project are ongoing, including the experimental project such as the 'tiny houses' and the urban farmland, but the realisation of the neighbourhood itself will start in 2018. (1)
Goals of the intervention
1. Develop a sustainable, climate-resilient and climate-neutral neighbourhood with a large community (3).
2. Improve and maintain the quality of the local environment and ecology of the area, as it is an important connecting zone (4)
3. As a sustainable feature, the neighbourhood is to have sustainable stormwater storage by means of a sustainable water system that will be built in which water is infiltrated, grey areas are restricted and water basins are created. Additional stormwater retention possibilities are being explored. (4)
4. Promotion of shared economy through initiatives such as sharing cars and bicycles (6).
5. Promotion of social cohesion in the form of creating collective spaces that citizens can design themselves and can create a community vegetable garden. (2,4)
6. As a sustainability feature, having the neighbourhood primary rely on sustainable energy resources, such as solar energy and geothermal energy (3,4).
Quantitative targets
For a period of 2 years, different experiments will take place in the area that will inspire the development of the sustainable neighbourhood including 1 urban farmland and 5 'tiny houses'. In total, 350 houses will be built from 2018 on. (6).

Creation of new sustainable urban district
Implementation activities
First phase(2016-2018):
- Creation of an urban farmland on which vegetables are grown and 5 'tiny houses' which are sustainable self-sufficient houses of 50m2 meant as pilot, organizing activities to inspire people, exchange knowledge and inform future citizens (1).
Second phase (2018-):
-Building of buildings with 350 flats with water-saving measures and solar panels (6), maintaining high citizen involvement in planning, designing, implementing and maintenance (3)
- Creating ecological river banks and green corridors (3)
- Creating collective spaces that citizens can design themselves (6)
- Reuse of materials of the allotment complex that is currently located in the area (1)
- Creating a community garden in which citizens can grow vegetables together (1)
- Promoting shared economy (1,6),
- creating a water system by means of infiltration and natural purification of water, restriction of grey areas, creating water basins, exploring water storing possibility underneath sport fields and possibility of a peripheral sewage system (4)

The municipality of The Hague planned to develop a new neighbourhood in the Erasmusveld-Leywegzone area. (5). The project 'Proeftuin Erasmusveld' was specifically initiated by the municipality of The Hague and project developer BDP (1). The municipality exploits the ground and organizes meetings with stakeholders (1,3). BDP is responsible for the actual development of the sustainable neighbourhood and has challenged designers to propose a design for the neighbourhood. The winning design is from a partnership between architects (marco.broekman, Workshop Architecten and LINT Landscape Architecture). A coalition 'Platform Erasmusveld' is created consisting of the municipality of The Hague and four project developers: Van Mierlo, Varese, ABB and BDP who finance the project and form ideas (4). The urban farmland is created by Stichting Lokaal Voedsel Den Haag (NGO), Woonpioniers (company) and urban farmer (Suzanne Monnier). Also (future) citizens are involved in all stages. (2).

Type of innovation
Please specify system innovation
The 'Proeftuin Erasmusveld' is a pilot project in The Hague on the extent to which citizens can collectively maintain their own neighbourhood and a 'sustainable community' can be created in which citizens truly live together and share properties and grow food together [3,4]. Currently (2016-2018) multiple citizen ideas are experimented with and the ideas that are most likely to succeed will be applied to the development of the neighbourhood. This can be considered a governance innovation as citizens 'create their own neighbourhood'. [2]. It can also be viewed as infrastructural innovation as it is the first time in The Hague that a neighbourhood is built that combines many sustainability benefits including climate change resiliency, biodiversity, sustainable energy and social cohesion and that tiny sustainable houses are created, that are completely self-sufficient as water is collected and energy is provided by solar panels [1,2,6].
Please specify novelty level of the innovation
'Proeftuin Erasmusveld' is a pilot project in order to analyze the development of a sustainable neighbourhood by the municipality of The Hague and is meant to inspire the development of future sustainable neighbourhoods [1,3]
Replicability/Transferability
Please specify Replicability/Transferability
The project is a pilot project that is meant to inspire other cities [3], therefore it is likely that parts of the project or lessons learned will be used for future projects. However, the project is still in planning stage and it is therefore difficult to estimate to what extent it will actually be replicated other locations in the city or in the Netherlands.
