Diante de um futuro incerto de mudanças climáticas, prevê-se um colapso em grandes cidades do mundo. O cenário é produto da insegurança alimentar gerada pelo distanciamento da agricultura local das áreas adjacentes ao espaço urbano, contexto já identificado em algumas civilizações no passado. Sob a perspectiva, assume-se que ações de planejamento urbano devem estar integradas a estratégias de produção de alimentos a incluir iniciativas em favor da agricultura urbana e periurbana, e de práticas da permacultura.

This paper discusses the agrarian problem in Brazilian rural areas from the environmental point of view. The objective is to examine how the private appropriation of the Brazilian rural space came about, attributing to the environmental factor a role whose logic was relevant in the inherited agricultural context. According to this hypothesis, the specificity of the private appropriation process of public land, after 1850, is the origin of agricultural and environmental problems in the Brazilian rural space.

The Enna Province is characterized by a low degree of economic, infrastructural and industrial development. Its hilly territory is a fair combination of many different and integrated landscapes. These conditions suggest the possibility of a sustainable development pattern in which the slow mobility, because of the low level of land infrastructures, can become one of the most important network

The area of the Strait of Messina, covering as trip of land that runs from Gioia Tauro to Melito Porto Salvo, on the Calabrian side and from Milazzo to Giardini Naxos on the Sicilian side, is bounded by the Aspromonte Massif and Peloritani Chain that create a room in the landscape: the empty water square of the Strait.

Desde os primeiros recortes territoriais do grande Recife, as igrejas pontuam o cenário urbano com suas torres, seus adros e pátios, sendo fortes símbolos de reconhecimento e identificação de bairros da cidade. As igrejas e seus pátios e adros fizeram parte dos primeiros engenhos e sesmarias, depois freguesias, hoje bairros, conferindo uma certa ambiência urbana que não foge à regra sobre a forma de ocupação característica do Brasil colônia, foram e são espaços de convivência da sociedade das cercanias, constituindo hoje espaços públicos e laicos na maioria das vezes.

Desde las primeras divisiones territoriales del Gran Recife, las iglesias puntúan el escenario urbano con sus torres, sus atrios y patios, siendo fuertes símbolos de reconocimiento e identificación de barrios de la ciudad.

Construites à partir des années 1960 sous l’impulsion du Schéma directeur d’Aménagement et d’Urbanisme de 1965, cinq villes nouvelles ont vu le jour en région parisienne. Leur aménagement laisse entrevoir une volonté de répondre à des besoins urbains identifiés, se conjuguant parfois avec l’offre d’espaces, de services ou d’équipements envisagés alors comme novateurs. Maurepas, rattachée jusqu’en 1984 à l’agglomération nouvelle de Saint-Quentin-en-Yvelines, a été façonnée en partie par ces aspirations.

El Plan Regulador Comunal es el instrumento normativo de planeación urbanística chilena, cuya formulación pretende regular en el ámbito comunal básicamente los siguientes aspectos: los usos de suelo, las condiciones de edificación y subdivisión del suelo, la red vial estructurante y los limites urbanos.Se cree que este instrumento es imperfecto toda vez que no incorpora en la normativa una dimensión clave del urbanismo: la morfología urbana, entendida como el sistema espacial tridimensional de la ciudad.

In the fi rst part of the article we give an account of the urban transformations that took place in Latin American cities, especially in Argentina, with the implementation of neoliberal politics since the seventies. We assume that neither the architectural facts, let alone urban

This research focuses the land and urban legalizing process of spontaneous shantytown settlements between 1980 and 1999, from the perspective of three such communities, located in the state of Rio de Janeiro and which form the basis of this case study. The aim of this work is to suggest different possibilities to intervene in these areas from a urban and land standpoint. Despite not being the only solution to the housing problem, it was found that the land formalization process helps improve the lives of vast numbers of people which today live in inadequate housing arrangements.

Por más de dos décadas, en la Región de Aisén, en la Patagonia chilena, se vienen proponiendo modelos y estrategias de desarrollo innovadoras en busca de sustentabilidad.
