12.4.Conclusion

The process of sustainable urban development must address all the dimensions of the contemporary societies with the people in its very core. The synergies of the existing dimensions of the cities and the urban environment must enable the creation of a comprehensive and viable approach to the pending problems through creation of integrated and sustainable solutions. This process for achieving sustainability must provide both a theoretical approach and a practical methodology stated in the New Urban Agenda and the Global Development Goals in order to address the urban challenges defined and depicted by the institutions, researchers and citizens in a comprehensive and complex way.
