Planning: between protests and calls to pick up the pace

Major infrastructure projects of (supra-)regional significance are complex and expensive, and expectations for their execution and effectiveness are accordingly high. Such projects include transport routes like railways and motorways, their bridges and tunnels (e.g. the Fehmarn Belt tunnel), and airports. They also include energy production sites, transmission lines like Südlink, or supra-regional projects for water management, waste management, communications, and other sectors.

All of these long-range investments in the future are not only very challenging in terms of their planning, engineering, and construction, but their environmental and social impact also harbours considerable potential for conflict, as projects like Stuttgart 21 have shown. Planning processes aiming for sustainable, integrated spatial development always take place among conflicting interests, cost-benefit considerations, and numerous risk assessments. They are expected to enable participation, to account for environmental and nature protection aspects, to integrate various sectors, and to be legally irreproachable in their processes and outcome. At the same time, there is growing pressure for planning processes to be faster.

Key aspects

  • Sustainability and integrative planning
    • How can major infrastructure projects be designed for sustainability, to minimise negative impacts on people and the environment?
    • How can the consideration of different social, economic, and ecological interests be integrated in spatial planning for major infrastructure?
    • How can gender mainstreaming perspectives be taken into account in major infrastructure projects, and what contribution do they make?
  • Planning law and accelerated planning
    • How can planning processes be sped up while also ensuring integrated planning with a secure legal basis?
    • Is planning by legislation a model for the future of major infrastructure projects in Germany?
    • How can cross-border infrastructure projects be coordinated and planned across different legal and planning systems?
    • How are large infrastructure projects planned and implemented in other countries and planning cultures?
  • Costs, benefits, and risks
    • How should the costs and benefits of infrastructure projects be assessed – beyond mere economic and commercial calculations?
    • How adequately are risk assessments and concerns around protecting the environment and nature taken into account in planning for major infrastructure
  • Participation and conflicts 
    • How can participatory and cooperative planning ensure that the interests and needs of all relevant stakeholders are taken into consideration?
    • Which planning strategies and procedures can help to minimise or resolve conflicts over the aims, interests, and uses associated with large infrastructure projects?
