Permeability and urban heat island effect; analysis and project for the mitigation of problems and for a renovation of the Sambodromo neighborhood.

Resilience of cities, involves a broader category of stakeholders, but particularly those associated not only with technical networks like water, electricity, sewage, waste disposal, and telecommuni­cations, but also with agriculture, mining and othe.- broader interests in society. lt is very much con­cerned with the need to ensure the supply of external resources needed to sustain today's cities. When turning resilience theory towards practice it should be noted that since we build on a systems ap­proach we aim to deliver knowledge that can generate systemic changes so as to generate more sus­tainable trajectories. Research so far has proposed more general notions for practice on how to build urban resilience, including: (i) enabling high rates of innovations; (ii) maintaining diversity (both so­cia) and ecological, (iii) maintaining modularity, (iv) restoring lost ecological functions, (v) tighten­ing feedback loops, (vi) building socia! capitai and add.-ess equity, and (vii) building overlap in govern­ance (Walker and Salt 2006; Ernstson et al. 2010). In taking these genera] notions into more concrete applications more work needs to be done, especially in relation to urban planning as a process and practice

La resilienza delle città coinvolge una categoria più ampia di parti interessate, in particolare quelle associate non solo a reti tecniche come l'acqua, l'elettricità, le acque reflue, lo smaltimento dei rifiuti e le telecomunicazioni, ma anche al l'agricoltura, al l'industria mineraria e ad altre. - interessi più ampi nella società. È molto preoccupato per la necessità di garantire l'approvvigionamento di risorse esterne necessarie per sostenere le città di oggi.
