Our regular presence in UN-Habitat's activities began at WUF7 in Medellin in April 2014, where we organized a networking event, titled “Equity and Equality Opportunities – Cities Think Underground”. On September 16, 2014, UN-Habitat and ACUUS signed an MOU to raise awareness of best practices of the sustainable uses of underground space for urban development, in particular for adequate urban drainage management, city planning, and sustainable mobility solutions, among decision-makers, local authorities as well as UN-Habitat staff. ACUUS was invited to organize an Urban Lab Session during the opening day of the Urban Thinkers Campus, in preparation of Habitat III, in Caserta, Italy, in October 2014. The Session was titled “Advanced Local Energy Planning and Underground Space Utilization: suitable and feasible solution for future sustainable and resilient cities”. On October 2015, our Secretary General participated in New York, as a Member of the Working Group 1 "The City We Need (TCWN) 2.0 Drafting Committee”, to the meeting of the WUC 13th steering committee. More recently, in February 2018, we hosted another Networking Event in the AFINUA Room at the World Urban Forum 9, in Kuala Lumpur, titled “Cities need underground – Equity and equality opportunities for the New Urban Agenda”.

A second MOU with UN-Habitat 

Signature MOU with UN Habitat

After a couple of months of discussions with UN-Habitat to draft the final version of our new MOU, valid for 3 years, we finally signed it in Shanghai on October 27, during the World Cities Day Global Cities Forum. On behalf of Ms. Maimunah Mohd Sharif, Executive Director of UN-Habitat, it was Mr. Victor Kisob, UN-Habitat Deputy Executive Director who signed the MoU with us.

In that important agreement:

  • ACUUS gained a much broader scope of activities regarding urban areas, and the focus and the primary results of our collaboration is the contribution of the Urban Underground Space (UUS) to the urban sustainability and resilience.
  • There are still no funding obligations by parties, but we will organize joint trips, and “each party can be invited and participate on each other’s events, seminars, conferences, workshops and other similar events and occasions and consider recommendations of visiting Party in formation of reports and recommendations resulting from this cooperation.”
  •  UN-Habitat will consult ACUUS on issues related to policies, best practices, lessons learned, strategic consulting or technical advisory on matters of urban space planning and urban underground space inclusion, and will actively participate in review of ACUUS documents and policies regarding urban underground space planning, with consideration of its inclusion in the planning process;

The Associated Research Centers for the Urban Underground Space joins the World Urban Campaign

Published April 7, 2015

ACUUS is an international ‘Think Thank’ for the underground space definition and planning initiatives with a continuous goal of broadening the membership across continents and countries. To achieve this, ACUUS hosted last year in Medellin, a networking event at the Seventh Session of the World Urban Forum, and signed a MOU of collaboration with UN-Habitat in September 2014, to promote the sustainable use of the underground space. Last October 2014, ACUUS participated to the Urban Thinkers Campus in Caserta, Italy, another initiative of UN-Habitat in preparation of Habitat III. 

As a result of those activities, the Associated Research Centers for the Urban Underground Space now joins forces with the World Urban Campaign. The Campain seeks to facilitate collaboration and bring people together to create a better and sustainable urban future for all. If you are interested to help us in that campaign, please contact the Secretariat.

A big step forward: Cooperation agreement between UN-HABITAT and ACUUS

Montreal, 24 September 2014

The date of September 16th 2014 is remarkable for our organization. A Memorandum of Underground was signed between The United Nations Human Settlement Programme (UN-HABITAT) and the Associated Research Centers for the Urban Underground Space (ACUUS), aiming to establish an official collaboration for raising awareness of the sustainable use of underground space for urban development. Since inauguration of ACUUS Secretariat in Montreal in 1996, our organization incorporated in Canada has maintained an international network of institution members and professional members located in 15 countries around the world. This agreement will allow ACUUS and UN-HABITAT to collaborate and work together to share and transfer the benefits, lessons learned, best practices, advantages and financing opportunities of underground space maintenance and development for its sustainable usage within a context of urban development, resilient cities and disaster risk deduction.

The ceremony was held in the UN-HABITAT New York office, with presence of ACUUS General Manager Mr. Jacques Besner, UN-HABITAT Executive Director Dr. Joan Clos, and ACUUS Secretary General Mrs. Sanja Zlantanic (From left to right in the photo below). Official announcement is published in UN-HABITAT’s front page, please refer to: http://unhabitat.org/cooperation-agreement-promotes-sustainable-use-of-underground-urban-space/.
