Po Delta, Italy (regional visioning)

Student design project – International Summer School 2011 – Venice Institute of Architecture
Team – post-graduate students of planning and architecture from Venice, Vilnus, Bucharest and Sheffield.

Brief: 
Develop scenarios for the delta region of Italy's largest river; the Po, and explore the impact of climate change on the landscape and thus its environmental, social and economic structures over one hundred years.

The Delta has always been a fragile environment












Concept: 
The Positive-trend Scenario - Land use, management and form adapt to rising sea levels and surface temperatures, resources and facilities are re-organised to the ensure sustainability of livelihoods.


















Strategies:
  • Allow sea defences to be breached.
  • Allow the growth of swampland to form natural barriers between the salt water and irrigated agricultural fields.
  • Encourage eco-tourism based upon 'experiencing the changing landscape'.
  • Allow new lagoons to form providing greater area for expanding shell-fish farming.
  • Reduce fish farming and hunting industries.

















Narrative:
In the 1700s the Po was redirected toward the south in order to prevent it's silt disrupting access to the Republic of Venice. The result was the formation of the delta; a man made landscape subsequently shaped to provide rich agricultural resources.

However the majority of residences and activities remain four meters below sea level; protected by constant drainage, irrigation, desalination and sea defences. Tourism is a growing sector based upon the areas of nature reserve. Shell-fish farming makes use of the shallow lagoons that are open to the sea. Conventional fish farms occupy highly controlled basins which provide less employment.

A positive-trend scenario accepted the future rise in sea level and surface temperature over the next hundred years, and sought to focus resources and facilities to ensure the sustainability of livelihoods by adapting land use and management practices.
The project was  the focus of the International Summer School 2011 hosted by the Institute of Architecture of Venice, involving post-graduate students from Sheffield, Vilnus, Bucharest and Venice. Inter-disiplenary teams were formed consisting of planning, urban design, architecture and landscape students.
