Detailed, up-to-date information on intra-urban land cover is important for urban planning and management. Differentiation between permeable and impermeable land, for instance, provides data for surface run-off estimates and flood prevention, whereas identification of vegetated areas enables studies of urban micro-climates. In place of maps, high-resolution images, such as those from the satellites IKONOS II, Quickbird, Orbview and WorldView II, can be used after processing.

Dhaka city in Bangladesh has been passing through a hasty process of urbanization and population growth since the last few decades. Rapid growth of population, unplanned urbanization and industrialization in the periphery has generated pressure to the changes in land use pattern, which has also caused huge urban expansion. This expansion process is engulfing cultivated land, vegetation, wetlands and water bodies without considering their environmental impacts.

Climate change and energy saving are challenging the city and the territorial organization. Innovative spatial and urban planning methods and procedures are required, and new approaches and instruments must be elaborated and applied in order to shift from the building scale to the urban and territorial ones.

• There is an accute lack of well-located urban housing that is adequate, secure, and affordable. The global affordable housing gap is currently estimated at 330 million urban households and is forecast to grow by more than 30 percent to 440 million households, or 1.6. billion people, by 2025.

The New Urban Agenda represents a shared vision for a better and more sustainable future – one in which all people have equal rights and access to the benefits and opportunities that cities can offer, and in which the international community reconsiders the urban systems and physical form of our urban spaces to achieve this.

O Perfil Rápido do Sector Urbano para Sustentabilidade (RUSPS) é um processo de avaliação rápida e proactiva de necessidades urbanas e lacunas de capacitação institucional a níveis nacional e das cidades. Esta avaliação está sendo implementada actualmente em mais de 20 países em África e Estados árabes. A metodologia RUSPS consiste em três fases: (1) uma abordagem participativa de perfil urbano, a níveis nacional e local, com enfoque na

We propose a methodology for the evaluation of urban walkability, and the related software tool for decision and planning support. In the introduction, we discuss the relevance of the concept of walkability for urban quality of life, and attempt to place it within the framework of the capability approach. The central part of the article is dedicated to the presentation of the spatial multi-criteria evaluation model for walkability.

The present paper stems from the evidence that one of the reasons of the “crisis” of today's cities probably depend on mobility issues.   But what should be done to confront all the negative impacts of passenger transportation, without curbing mobility? Can Urban Engineering be applied to promote a friendlier mobility, that should be not only environment and climate friendly, but user friendly as well? And how?

Landscape connectivity is one of the major issues related to biodiversity conservation and to the delivery of Ecosystem Services (ES). Several models were developed to assess landscape connectivity but lack of data and mismatching scale of analysis often represent insurmountable constraints for the correct evaluation and integration of ecological connectivity into plans and assessment procedures. In this paper a procedure for ES assessment related with Habitat and Bio-Energy Landscape Connectivity (BELC) is proposed.

Se evoca la labor de un profesional chileno, el arquitecto y urbanista Luis Muñoz Maluschka (1896-1974), en el marco de un período de cincuenta años de aportes relevantes en planificación urbana y ordenamiento territorial realizados desde el Ministerio de Obras Públicas de Chile./The work of a Chilean professional architect and city planner, Luis Muñoz Maluschka (1896-1974) is commented. In fifty years he has made important contributions to urban planning and land arrangement from the Ministerio de Obras Publicas (Ministry of Public Works.)

Transport policy is one of the most crucial sectors in the process of adaptation of contemporary cities to the challenge of sustainable development. For its close relation with social habits and people behaviors, in fact, innovation in transports play a strategic role both in the decreasing of the environmental impact of mobility and in the improvement of the quality of the built environment. To do so, however, cities need to reach a more effective integration between transport policy and land-use planning, as well as taking full advantage by the spreading of new technologies.
