The Po valley is one of the most polluted areas in Europe. Agricultural and industrial demand have led to thorough exploitation of the area by deforestation and urbanization, and its lack of forests and ecological connections have expedited the loss of biodiversity and the many ecosystem services woods provide. This thesis has two main objectives. Firstly, this study aims to examine global issues regarding forests and provide a contextualized understanding to the history, culture, and existing conditions of the Po Valley. Secondly, the project presents a collection of tools and nature-based solutions implemented in urban planning strategies, urban design, and architecture to establish ecological connections and transition towards sustainable and resilient land use. To demonstrate the findings and design solutions, the proposal is applied in a sample area of 50 x 50 km in the province of Ferrara. The area includes a high-risk flood zone and a number of abandoned agricultural fields and post-industrial land. Tree and plant samples are recorded and strategically planned to carry out phytoremediation on contaminated soil, and abandoned areas are classified and repurposed with increased ecological and landscape value. The masterplan and its corresponding designs will fully be implemented by year 2100, with an additional 182.91 square km of woods and ecological corridors, absorbing and safeguarding more than 12 billion cubic meters of freshwater and capturing and storing 20 million tons of carbon dioxide. Incremental evaluations and periodic monitoring of the planned green infrastructure is necessary to ensure its maintenance and benefits, while the Eridania Park in the city of Ferrara will provide more than 10 hectares of recreational wooded space, equipped with event spaces and vast green areas for public enjoyment. On this basis, other municipalities and organizations may use this proposal as a reference in moving towards a better-connected green infrastructural network for building a sustainable and resilient Po Valley.
Il fiume Po attraversa una delle zone più inquinate d’Europa. Domanda agricola e industriale hanno portato ad uno sfruttamento intensivo dell’area; deforestazione, urbanizzazione, mancanza di sistemi boschivi e connessioni ecologiche hanno accelerato la perdita di biodiversità. Questa tesi ha due obiettivi principali. In primo luogo, lo studio propone di introdurre il lettore alle questioni a carattere globale riguardanti foreste e sistemi agroforestali, facendo riferimento a storia, cultura e condizioni ambientali esistenti nella valle del Po. In secondo luogo, il progetto presenta una raccolta di strumenti e possibili interventi strategici di pianificazione, progettazione urbana e architettonica mirati a ristabilire un territorio maggiormente sostenibile e resiliente attraverso l’incremento di foreste, parchi, percorsi, sistemi agroforestali. Le soluzioni progettuali proposte trovano applicazione in un’area campione di 50 x 50 km in provincia di Ferrara. L’area racchiude una zona alluvionale ad alto rischio idraulico, molteplici campi agricoli abbandonati e aree post-industriali in disuso. Alberi e piante divengono lo strumento strategico per mitigare il rischio idraulico, eseguire il fitorisanamento sui terreni contaminati, ristabilire i corridoi ecologici, attribuire un valore estetico-percettivo ai percorsi nel paesaggio. Il masterplan e i relativi interventi progettuali saranno completati entro il 2100 con la piantumazione di oltre 180 chilometri quadrati di boschi e corridoi ecologici, assorbendo oltre 12 miliardi di metri cubi di acqua dolce e catturando e immagazzinando 20 milioni di tonnellate di anidride carbonica. Il monitoraggio periodico delle infrastrutture verdi previste sarà necessario per garantirne manutenzione e benefici nel breve, medio e lungo periodo. Il parco di fitorimediazione in progetto nell’ex fabbrica Eridania alle porte di Ferrara metterà a disposizione oltre 10 ettari di superficie boschiva a scopo ricreativo, con spazi per eventi e vaste aree verdi di pubblica fruizione. A partire da questo progetto pilota, altri comuni e amministrazioni provinciali e regionali possono iniziare a ripensare la rete infrastrutturale verde come dorsale sostenibile e resiliente nel territorio urbanizzato della valle del fiume Po.

Abstract
The Po valley is one of the most polluted areas in Europe. Agricultural and industrial demand have led to thorough exploitation of the area by deforestation and urbanization, and its lack of forests and ecological connections have expedited the loss of biodiversity and the many ecosystem services woods provide.

Firstly, this study aims to examine global issues regarding forests and provide a contextualized understanding to the history, culture, and existing conditions of the Po Valley. Secondly, the project presents a collection of tools and nature-based solutions implemented in urban planning strategies, urban design, and architecture to establish ecological connections and transition towards sustainable and resilient land use.
