We have been designing school gardens, river banks, urban forests and city\u00a0parks over the last 12 years. I\u2019ve written\u00a0about school garden and city park design project in former articles<\/a>. The aim of these projects are to create areas for children’s play, ecological education, and biodiversity preservation that can simultaneously form part of an ecological network in an urban area. In this blog, a\u00a0nature restoration project at a riverbank has been planned\u00a0in the northern part of Kyushu, Japan. The ministry of Ministry on Land, Infrastructure, Transport and Tourism asked us (Keitaro ITO Lab., Kyushu Institute of Technology, Japan) to design a new fishway and river mouth surrounding area as an ecology park. In this blog, I would like to focus on river landscape design process and nature restoration and discuss urban ecology.<\/p>\n

The Planning and design site<\/strong><\/p>\n

The River Onga in Fukuoka Prefecture, Kyushu, Japan, has a total length of 61 km and a catchment area of 1,026 km2<\/sup>. The urbanised areas have dramatically expanded at the surrounding area of the river. The population at the surrounding area of the river is around 670,000 people, and the population density is around 650 per square km. The surrounding area of the river is composed of mountains (80%), agriculture area (14%) and residential area (6%). The river has contributed to local society, economics and culture over the centuries, thus there have been many linkages between local people\u2019s life and the river.<\/p>\n

Planning and Design process<\/strong><\/p>\n

We conducted our basic design process during October 2008 through March. As in our previous projects in\u00a0school gardens<\/a> and city park<\/a>, we used \u201cprocess planning\u201d. The fundamental principles of our landscape design are as follows: (1) using local materials; (2) avoiding artificial shapes; (3) creating play spaces for children; and (4) enhancing native biodiversity. According to the above principles, we stated \u201cRestoration of a waterfront space linking between people and living nature\u201d as the design concept. The figures below\u00a0show the informal\u00a0design\u00a0sketches by Keitaro ITO. And the 1\/100 model was made by the students in Keitaro Ito Lab.<\/p>\n

Practical planning was held April 2009 through September 2010 with MLIT staff, university students, local government staff, residents, children and consultants. Collaborative work was conducted in\u00a012 workshops.<\/p>\n

Construction and use process<\/strong><\/p>\n

The construction process occupied\u00a0one and half years, October 2010 to March 2012. At first, we got rid of the concrete structure and recycled them for fixing the underground structure at this site. Finally, the site was\u00a0gradually covered with grasses and trees; areas children could occupy. Also, the site at the end of the lower fishway was designed for a tidal flat which could\u00a0attract both\u00a0water creatures and\u00a0birds. Although tidal flats used to exist everywhere at river mouth areas in Japan, it has currently become rare due to concrete embankment construction. Consequenctly, very significant ecosystems at tidal flat areas are threatened. The can be a special place for an an environmental education opportunity for local children\u00a0to observe ecosystems .<\/p>\n

Local people\u2019s participation<\/strong><\/p>\n

Four workshops took place in order to share this design concept and process with local people, So, it was expected that they\u00a0would become close to this ecology park before completion of\u00a0the\u00a0renovation work. The local government and people must\u00a0manage the park in the future. It should be noted that the local people\u00a0knew that a core reason for the park was ecological restoration and education, and that these elements must be incorporated into the maintenance. The attendees were the students from our university, the Ashiya-town government, Ashiya-Higashi primary school, and local nature protection members.<\/p>\n

Now (July 2014) we are in next stage of the project and challenging ourselves on how to manage the fishway and grassland for urban biodiversity. The detailed design process and ecological monitoring data will be coming soon in a\u00a0book and papers.<\/p>\n

The park was designed & formed as a space for nature restoration at the weir across the mouth of River Onga in Fukuoka which used to be covered by concrete.<\/p>\n
