El Desarrollo Sustentable constituye el paradigma actual dominante para orientar el desarrollo económico y social de la humanidad. A pesar del aparente acuerdo global acerca de su importancia, su aplicación práctica es de difícil instrumentación, especialmente en el medio urbano latinoamericano, donde son múltiples las brechas que separan la ciudad actual de la deseada ciudad sustentable. Algunos aspectos para el análisis de la ciudad, el ambiente y el desarrollo sustentable son discutidos en este artículo, en un intento por contribuir con la comprensión de la realidad urbana de la ciudad latinoamericana y las posibilidades de alcanzar su desarrollo sustentable.

    ABSTRACT: The purpose of this paper is to provide a broad overview of the recent patterns and trends of urban growth in developing countries. Over the last 20 years many urban areas have experienced dramatic growth, as a result of rapid population growth and as the world's economy has been transformed by a combination of rapid technological and political change. Around 3 billion people—virtually half of the world's total population-now live in urban settlements. And while cities command an increasingly dominant role in the global economy as centers of both production and consumption, rapid urban growth throughout the developing world is seriously outstripping the capacity of most cities to provide adequate services for their citizens. Over the next 30 years, virtually all of the world's population growth is expected to be concentrated in urban areas in the developing world. While much of the current sustainable cities debate focuses on the formidable problems for the world's largest urban agglomerations, the majority of all urban dwellers continue to reside in far smaller urban settlements. Many international agencies have yet to adequately recognize either the anticipated rapid growth of small and medium cities or the deteriorating living conditions of the urban poor. The challenges of achieving sustainable urban development will be particularly formidable in Africa.

    ABSTRACT: The concept of sustainability has received much attention since the publication of Our Common Future by the World Commission on Environment and Development in 1987. Despite the institutionalisation of sustainability principles through legislation and policy around the world, progress in implementing sustainable development actions has been slow. The very open-ended definition of sustainable development provided in these documents, and the “language” used has made interpretation of what is required for implementation controversial. “Principles” of sustainable development have been developed to provide further guidance for implementation, but sustainability remains a contested and value-laden concept. Yet there is increasing recognition that the present development paths around the world are clearly not sustainable into the future and that we need urgently to address this unsustainability. Water use has become a prominent issue through broad acceptance that its use in many situations, including southeast Australia and cities such as Sydney, is unsustainable. This paper provides a broad introduction to the development of the concept of sustainability, barriers to implementation of sustainable development, and the application of sustainable development principles to water provision for a city such as Sydney, with emphasis on the use of recycled water.

    ABSTRACT: The major cities of highly industrialized societies are the nodes that connect a mass network of critical infrastructure services. Thus the cities themselves comprise the most critical infrastructure of the society. The resilience and robustness of the infrastructure of cities is thus essential to their sustainability. Since most of enterprises providing these services are privately or corporate owned and are highly competitive, their drive for economic efficiency also tends to make cities increasingly vulnerable to three kinds of disasters: technogenic, natural, and intentional. This paper explores the factors that govern the willingness or reluctance of private and corporate owners of critical services to invest in catastrophic risk reduction and the degree of public-private cooperation required to make cities more sustainable. Ultimately some changes in the political relationship between cities and states and the national governments that exercise sovereign authority over them will be required, as cities become the primary structure for the social and economic lives of people everywhere.
