DE-US.net – German Embassy, Washington, D.C.

USA – German collaboration to respond to strategic research demands on integrated spatial planning, land use and soil management

Shaping integrated social, healthy and resilient Municipalities: Effective investments for Sustainable Urban Development

You can see this here:




  • More than at anytime in history, urbanization is the dominant environmental, economic and social challenge determining whether earth stays on a sustainable trajectory. Cities in the US and Europe are at the center of efforts to promote resilient infrastructure, employment opportunities, healthy communities and feed their populations.
  • Building the „City of Tomorrow“ and promoting resilient cities highlight the importance of joint scientific, technical and policy cooperation at the metropolitan level between the US and Europe. This is especially the case with investments into resiliency with public funds and support for outcome-oriented integrated approaches in planning and urban development for more sustainable and resilient communities.
  • This call is reinforced in urban development strategies, such as the New Urban Agenda (Habitat III), the Urban Agenda for the EU or Sustainable Development Goals (SDGs).
  • In a workshop at the German embassy in Washington D.C., we will focus on the strategic approaches and research needs identified in Germany and the US in order to improve them and exploit synergies through future collaboration.
  • This special event is facilitated by DE-US.net – www.de-us.net – and INSPIRATION – www.inspiration-agenda.eu. We invite representatives from municipalities, academia provide solutions for sustainable and better living in the city of tomorrow.

Objectives and Anticipated Outcomes

  • Review of shared strategic research demands on urban resiliency in the US and Germany – Presentation of current strategies and agendas
  • Exchange about specific collaboration topics – All participants share their prior collaboration topics (e.g. a specific research question or follow-up on a cooperation project or a topic from their local development strategy …)
  • Identification of topics of common interest to strengthen transatlantic applied research on urban resiliency - Identification of topics where synergies of collaboration are likely
  • Prepare development of concrete project collaborations by reviewing experience on success and failure stories and collect available funding formats
  • Merging topics and formats: Deriving joint activities and clarify next steps
