Open space (OS) is a key element in the provision of ecosystem services (ES) in urban environments. Under a land cover-land use perspective, cities are incorporating into the expansion process to different types of surfaces: sealed, paved surfaces and OS. The first corresponds to a land cover change while the second, which includes bare soil, grass, forest or any other type of non-sealed surface, corresponds to a land use change, without physical transformations. As a land use change OS is able to keep fundamental pre-existing ecological properties.

Metropolitan Santiago is one of the many Latin American cities which has been developed according to a spread model of urbanisation. This pattern has caused at least two types of consequences: economic and physical ones. The former is shown in the speculation of land value at the rural fringe of the metropolitan area which has low prices, these have suddenly increased after the normative changes in the land use, from rural to urban. The later shows location of massive low-income housing and commercial malls regardless connection to the urban fabric and spatial shaping of the existing city.

Long-term field studies in the scope of a multidisciplinary project in southern Ecuador revealed extraordinary high species
numbers of many organismic groups. This article discusses reasons for the outstanding vascular plant diversity using a
hierarchical scale-oriented top-down approach (Grüninger 2005), from the global scale to the local microscale. The global
scale explains general (paleo-) ecological factors valid for most parts of the humid tropics, addressing various hypotheses -

The insufficient supply of serviced land at affordable prices for
the urban poor and the need for regularization of the consequent
illegal occupations in urban areas are two of the most
important issues on the Latin American land policy agenda.
Taking a structural/integrated view on the functioning
of the urban land market in Latin America, this paper discusses
the nexus between the formal and the informal land markets. It
thus exposes the perverse feedback effects that curative regularization -

Se analizan las relaciones existentes entre temperaturas urbanas y concentraciones de material particulado a una escala que representa la totalidad de la ciudad, destacando su división en dos zonas bien delimitadas, que ubicadas al oriente y poniente de la misma, durante los días de ocurrencia de las peores condiciones de contaminación atmosférica.

Este estudio analiza la relación entre la tenencia de títulos de propiedad (registrados) y los mercados inmobiliarios en zonas de la ciudad que tuvieron un origen informal y/o ilegal. Al hacerlo plantea cuestionamientos a los presupuestos internacionales y encuentra paradojas en el funcionamiento del mercado de suelo popular. La metodología es cuantitativa y cualitativa. Las conclusiones muestran que en asentamientos no consolidados la tenencia de un título de propiedad contribuye a un mayor valor de los predios con relación a aquellos no titulados.

Much of Guatemala’s recent forest loss has occurred in the emerging agricultural frontiers of the Maya Biosphere Reserve (MBR), the heart of the largest contiguous tropical forest in Central America—La Selva Maya.

The "road capacity" of the Chilean Master Plan is a tool developed to measure the capacity of streets in terms of supporting the size of vehicle flow. This tool considers topics such as land use, population density and street width. The purpose of this technique is to incorporate it to the Master Plan, as a town planning instrument, so as to cope with traffic forecasting and congestion. However, the technique does not embrace any sustainability concept, this is due to a disregard of any district ´s social or environmental needs.
