On the threshold of spring, that is where we are, where color invades us and light appears unexpectedly to brighten our day. But not everything is a time of joy. Although the pandemic is subsiding, a war is coming for which we were not prepared and for which there is no end in sight and with it the old concerns about food return. The dependence, recognized but not assumed, of other countries for our food is beginning to become obvious, as Catherine Steel has been narrating in a book with a long journey: "Hungry Cities". And who says food says energy. The problems are already here and the time has come to face them.

Thus, the first article and without having an immediate prominence when it was requested, it does have it today. With a very expressive title, "The edible coast" tells us about the situation of a potato-producing paradise, where monocultures are threatened by climate change, by the impoverishment of soils, the losses derived from biodiversity and the importance of the landscape intertidal, in danger of being submerged and the salinization of the Wadden Sea. All this requires facing uncertainty and proposes a new vision, the edible Wadden coast, in an area where, due to its productive wealth, food can be grown for 3.5 million people in quantity and diversity, with a productive landscape that focuses on the local environment.

In Amara Berri we find ourselves with a process of participation for the transformation of the public spaces of the neighborhood, previously perceived as insufficient, degraded, inactive and with little identity in the words of its users. It was about defining a Plan of more than twenty actions that range from tactical urban planning interventions to complete reforms of squares through collaborative design processes. Called PAM, the process conceives public space as a network of places related to other urban spheres, such as mobility, the urban landscape, socio-cultural diversity and facilities, among others. It is proposed as a methodology capable of facing the treatment of public space for its acceptance, appropriation and care by its users.

Without a doubt, nature acquires greater relevance every day in our cities. A good attitude towards the growing urbanity of the planet will require more and more that the nature-city relationship becomes intrinsic to the very nature of the city, worth the redundancy, so that nature becomes consubstantial to it as an element of social equity. and quality of life. The case of Medellin is a sample of processes that, to a greater or lesser extent, are taking place mainly in Latin America. In them, nature is being integrated into daily life and primarily in this city that advances unstoppably in its planning, from its pioneering transport actions to comprehensive urban projects that are sewing the fabric of the city, eliminating inequalities with the incorporation equipment and in line with the previous article, emphasizing public participation, not as a novelty but as a necessary process. At this time it is a matter of talking about the revitalization and improvement of natural components and environmental continuity, which is what this article is about to talk about, offering not only a working methodology but also references to specific projects, in a narration of past and future, on a “path that he travels daily in search of an inclusive, safe, resilient and sustainable city”.

There is no doubt that there are concepts that have already appropriated any urban action and appear recurrently in the projects, acquiring a charter of nature. No longer being the subject of debate, they are principles incorporated from the beginning and thus we are told of urban planning "beyond the conventional", as is the case of the work presented below in the Historic-Artistic Complex of Alcalá de Júcar. There are also integrated approaches that break physical barriers in which, as in the Central Park of Valencia, the park is no longer understood only in terms of design and green infrastructure but also incorporates the landscape vision, increasingly present, with the objective of creating a new urban ecology for the city, located in this case in a very powerful natural environment such as the orchard, the lagoon or the Turia reserve.

The built city can no longer be an obstacle to the biodiversity of the space in which one day it was born and in which it must necessarily be integrated and, as it is presented, "the infrastructural, cultural and natural framework of Valencia serve as a basis for design for the generation of Green Infrastructure within the city”. Once the first phase has been concluded, it is presented as a demonstration of the possibility of the coexistence of infrastructure and nature through design and the appropriate selection of vegetation. The park is conceived as a place where nature and the city interact, in a symbiosis between the natural landscape and the built landscape.

A similar intention guides the recovery of the Estancos de la Sal park in its connection to the Rimac River, recovering the transversal connections with the Historic Center of Lima and generating a new boardwalk. To these larger projects is added a project, on a smaller scale but of great significance, incorporated into the Camino de Santiago, such as the Plaza del Grano de León, in a rehabilitation action both in plan and elevation, in which the redesign and redevelopment of the square play an important role.

A greater design intention presides over the Ptuj Market Square in Slovenia from a significant start, "a square that never was". It is a space that was previously occupied by military barracks and is presented with a clear intention of respect and integration into the environment, where color and the use of local materials act as protagonists.

Thus, we close an issue that recurrently aligns the projects towards the assessment of sustainability, whether from nature, society and, today in an incipient way, from culture in broader consideration.
