L’urbanizzazione globale affronta oggi una crescita demografica naturale concentra nei paesi in via di sviluppo che comporta una costante ed incontrollata espansione degli slums e degli insediamenti informali. La maggior parte delle moderne città globali del sud del mondo sono composte, in alta percentuale, da persone povere o che vivono al di sotto della soglia di povertà. Questa sfida del nostro secolo, ad oggi, è stata spesso affrontata con due approcci principali, il primo, con effettivo disinteresse da parte dei vari governi ed istituzioni oppure, secondariamente, con il drastico intervento di demolitori atti a rimuovere comunità e quartieri per far spazio ad aree utili per ingenti operazioni speculative. Un tema così importante ha bisogno di essere affrontato, non può essere ignorato e la demolizione ed il ricollocamento in aree decentralizzate ne sono raramente la soluzione. Infatti ciò che la sfera del demolire distrugge non sono soltanto gli edifici, ma anche una fitta rete fatta di rapporti personali, memorie e pensieri, che, assieme a ciò che è cresciuto durante un lungo periodo, creano lo spirito della comunità e del luogo. La comunità smantellata soffre enormemente, tanto che è normale che tenti di riappropriarsi delle stesse zone o di aree adiacenti creando non pochi disagi e tensioni sociali. Politiche locali che tengano conto dei reali bisogni della maggioranza della popolazione, e che si inseriscano in un contesto di organizzazione generale sono necessarie per creare un’equilibrato, sostenibile e consapevole consolidamento delle comunità, dei quartieri e delle connessioni; si cerca così di evitare fenomeni di espansione incontrollata che creano realtà di densità abitatività insostenibile e la sempre più diffusa invasione informale di aree inadatte a causa di problemi ambientali. È pensabile interpretare questa situazione urbana, con approcci architettonici che nelle loro strategie sviluppino temi come la costruzione incrementale, come l’innesto in seno ad insediamenti spontanei di infrastrutture ecologiche e spazi pubblici, come l’alloggio modulare per famiglie e strutture igenico-sanitarie ed infine come lo sviluppo di tecniche di costruzione pratiche. L’azione del sovrappore ed addizionare questi elementi crea nuovi pattern di connessione che si innestano nella trama del tessuto urbano non consolidato esistente, delineando uno sviluppo locle più lento, ma costante e graduale. Questo tipo di architettura minuta ed interconnessa ha l’ambizione di riuscire ad essere attuata e contestualizzata su ampia scala, e di apportare cambiamenti che determinano una nuova estetica condivisa e processuale.

Abstract
The global urbanization today faces a natural population growth concentrated in developing countries, which involves a constant and uncontrolled expansion of slums and informal settlements. Most of the modern global cities of the southern hemisphere are composed, in a high percentage, as poor or living below the poverty line. This challenge of our century, to date, has often dealt with two main approaches, the first, with the actual lack of interest on the part of various governments and institutions or, secondly, with the drastic intervention of demolition acts to remove communities and neighbourhoods to make way to useful areas for massive real estate speculation. Such an important issue needs to be addressed, it cannot be ignored, and the demolition and relocation in decentralized areas are rarely the solution. In fact, what the sphere of demolishing destroys are not only the buildings, but also a dense network of personal relationships, memories and thoughts, which, together with what has grown over a long period, create the spirit of the pace and the community. The dismantled communities suffer greatly, so much so that it is normal that attempts to regain possession of those areas or adjacent areas, creating many hardships and social tension. Local policies that take into account the real needs of the majority of the population, and which are inserted in a context of general organization are necessary to create a balanced, sustainable and conscious consolidation of communities, neighbourhoods and connections; it thus seeks to avoid uncontrolled expansion phenomena that create reality unsustainable housing density and the growing of informal invasion of areas unsuitable because of environmental problems. It is conceivable to interpret this urban situation, with architectural approaches in their strategies to develop topics such as incremental building, such as grafting in breast to spontaneous settlements of ecological infrastructures and public spaces, such as modular housing for families and health and hygiene facilities and finally, as the development of practical construction techniques. The action of the superimposition and the adding these elements creates new connection patterns that are inserted into the not consolidated existing urban built up texture, outlining a slower local development, but steady and gradual. This type of small scale and interconnected architecture has the ambition to be able to be implemented and contextualized on a large scale, and to make changes that result in a new shared and procedural aesthetic.File | Dimensione | Formato | |
