Abstract Water-logging is a major challenge for Dhaka city, the capital of Bangladesh. The rapid, unregulated, and unplanned urbanization, as well as detrimental social, economic, infrastructural, and environmental consequences, not to mention diseases like dengue, challenge the several crash programs combating water-logging in the city. This study provides a brief contextual analysis of the Dhaka’s geomorphology and natural plain, as well as, storm water drainage systems, before concentrating on the man-made causes and effects of water-logging, ultimately exploring a few remedial measures.

There existed a large number of water bodies including rivers, Khals, lakes and low-lying areas in Dhaka, a thickly populated City and capital of the country. The water bodies played important roles on the natural environment of the City including its drainage system. Due to various natural and human induced reasons, the wetlands of the City have been shrinking with the passage of time. This study makes an attempt to identify the urban wetlands, emphasizing on the extent of their changes and subsequent impacts on physical environment of the area. For ascertaining the land-use pattern of the City, this study uses topographical map (Toposheet of 1960) and satellite images (Landsat TM, 1988 and ALOS VNIR, 2008). It also uses remote sensing and GIS based software (e.g. Arc GIS, Erdas Imagine) for this purpose. Statistical analysis has been carried out in order to process and analyze the data. The study observes that the wetlands of Dhaka city are changing very quickly. In 1960, the total area of water bodies and lowlands were 2952.02 and 13527.58 ha, respectively. Whereas in 1988, the total area of the same decreased to 2103.62 and 12717.73 ha, respectively. This deteriorated further, occupying an area of 1990.71 ha in 2008 which indicates that the lowlands continued to decrease. Thus the water bodies and lowlands decreased by 32.57% and 52.58%, respectively during 1960 and 2008. This changing trend of wetlands makes the drainage system of Dhaka City vulnerable, creating water logging problems and their consequences. Land filling and encroachment were recognized to be the main reasons for changing wetlands in the City. Key words: Wetlands; wetland changes; water logging; environment DOI: 10.3329/jles.v5i0.7348 J.

For quite some time, professional planning is being practiced in our cities. Unfortunately, drainage planning is the most neglected component of our city planning and management activities. Drainage engineering is done mostly on an ad hoc basis, often overtaking drainage planning. To understand the drainage problem of our cities, Chittagong in particular, Chaktai Commercial Area was identified as the case study area for further exploration and analysis. This case study examines the existing situation, assessing causes behind the problems, inquiring about the likings and disliking of the stakeholders, and identifying possible solutions as an essential input towards arriving at appropriate planning decisions. It identifies the guiding principles relating to the effective integration of a drainage network in the land use plan for the city. Considering physical characteristics, topography, catchment area and the routes of existing drainage channels, the urban area has been divided into 10 drainage areas. The Master plan sets out a staged development program of storm water, drainage and flood control works of the above drainage area up to the year 2015 to meet the Storm Water Drainage and Flood Control problems. Chaktai is the major seat of trade and commerce in Chittagong. It is observed that though Chaktai has lost its past glory as a national business centre controlling food business in the whole country, still it has retained its importance as a regional business hub and is continuing to contribute significantly to the national economy. The study thus helps us understand the nature, type and magnitude of the drainage and water logging problems faced by the city dwellers. The policy proposals and recommendations that are provided in the paper could be considered while preparing a land use plan for a city.DOI: http://dx.doi.org/10.3329/jbip.v2i0.9556  Journal of Bangladesh Institute of Planners Vol. 2, December 2009, pp. 49-60

El artículo pone en tensión la disputa en el agro contemporáneo de dos modelos antagónicos de producción, como también de tradición y relación con la naturaleza: el agronegocio y la agroecología. Destacamos los casos argentino y brasileño de producción agrícola de la soya en las recientes décadas, intensificada por el “boom de la soya”, es decir, el agronegocio sojero. Entendemos esa producción como un caso paradigmático, por evidenciar la profundidad del agronegocio y de sus consecuencias sociales, económicas y ambientales. En oposición a ello, acentuamos a la agroecología como un paradigma sustentable ambientalmente, y social y económicamente armónico. Así, va más allá de un modelo de producción agrícola, en la construcción de buenas condiciones de reproducción de la vida en el agro y en la ciudad. El artículo se divide en tres apartados. En el primero abordamos los fundamentos de formación del padrón de producción agrícola que conlleva al agronegocio. En el segundo nos centramos en el fomento del agronegocio sojero en Argentina y Brasil. En el tercero analizamos la agroecología como un proceso disruptivo que está en constante tensión con aquel modelo de producción agrícola. Abstract This article puts in tension the dispute between two antagonistic models of agricultural production in the contemporary agriculture, as well as tradition and relationship with nature: agribusiness and agroecology. We highlight the Argentine and Brazilian cases of soybean production in recent decades, intensified by the “soy boom”, that is, soybean agribusiness. We understand this production as a paradigmatic case, for evidencing the depth of agribusiness and its social, economic and environmental consequences. In opposition to this, we emphasize agroecology as environmentally sustainable, socially and economically harmonious paradigm. Thus, it goes beyond a model of agricultural production, in the construction of good conditions for the reproduction of life in agriculture and in the city. The article is divided into three sections. In the first, we address the fundamentals of forming the pattern of agricultural production that leads to agribusiness. In the second we focus on the promotion of the agribusiness in Argentina and Brazil. In the third, we analyze agroecology as a disruptive process that is in constant tension with that model of agricultural production.

Research Question: This analysis arises from the decision of the current local council of Barcelona regarding the postponement of the sporting mega-event ‘World Roller Games’, due to a lack of a social and sportive implication in this event. This research tries to shed some light on the matter and give evidence to the local council to become the world capital of skating. The research question is to analyse whether non-economic impacts could be relevant enough to organise a mega-event.Research Methods: The methodology is based on the perception and experience of spectators and participants on four main impacts (social, economic, sports city image and sports practice) using a survey from a National Roller Skating Championship in Spain, considering that this profile of respondents have a better knowledge of the current situation of this sport.Results and Findings: There are positive expected future consequences of this mega-event to be held in Barcelona in social and sportive terms. We can also conclude that the local council must still introduce some social and sportive policies in the city in order to improve the chances of success in social, sports practice and sportive brand image development.Implications: It is demonstrated that a mega-event should not be seen purely from a perspective of business generation, especially with minority sports like roller skating. There is a clear opportunity to develop social and sportive practice initiatives that can push social cohesion throughout the city thanks to a mega-event such as this one.

The second afterword to the book by Kamran Asdar Ali returns us to the city, and to the lives of Karachi’s working women and working classes. He draws on women’s poems, diaries, and memoirs to capture some more ephemeral qualities of everyday living and dying. These contrast with the violent suppression of an underclass of trade unionists and labor activists by a coalition of the state, military courts and industrialists, since the fifties. Given the long, progressive erosion of peace in Karachi how, he asks, might we imagine a therapeutic process of social, economic and cultural healing? Through an image of citizens “at work” creating citywide networks and connections, we are offered finally some possibilities of dreaming. Namely, through increased understandings, not of conflict, but also of each other’s intimate everyday lives, the dream emerges of a new political space or public where even intractable disagreements can be managed through gestures of kindness, compromise, and fresh vocabularies of how to carry on and get by.

Since the advent of the second digital revolution, the exponential advancement of technology is shaping a world with new social, economic, political, technological, and legal circumstances. The consequential disruptions force governments and societies to seek ways for their cities to become more humane, ethical, inclusive, intelligent, and sustainable. In recent years, the concept of City-as-a-Platform was coined with the hope of providing an innovative approach for addressing the aforementioned disruptions. Today, this concept is rapidly gaining popularity, as more and more platform thinking applications become available to the city context—so-called platform urbanism. These platforms used for identifying and addressing various urbanization problems with the assistance of open data, participatory innovation opportunity, and collective knowledge. With these developments in mind, this study aims to tackle the question of “How can platform urbanism support local governance efforts in the development of smarter cities?” Through an integrative review of journal articles published during the last decade, the evolution of City-as-a-Platform was analyzed. The findings revealed the prospects and constraints for the realization of transformative and disruptive impacts on the government and society through the platform urbanism, along with disclosing the opportunities and challenges for smarter urban development governance with collective knowledge through platform urbanism.

AbstractThe sustainable urban redevelopment project to protect biodiversity was developed to regenerate the external spaces of an ancient rural farmhouse, Villa Framarino, in the regional Natural Park of Lama Balice, a shallow erosive furrow (lama) rich in biodiversity, between two suburbs of the city of Bari (Apulia, Italy) and close to the city airport. This work includes a complex system of activities aimed not only at a spatial revaluation, necessary to relaunch the urban image, but it is accompanied by interventions of a cultural, social, economic, environmental and landscape nature, aimed at increasing the quality of life, in compliance with the principles of sustainability and social participation. One of the means to revitalize a territory subject to redevelopment is the planning of events and activities of socio-cultural value that involve the population to revive the sense of belonging to the territory and the community and at the same time to protect the biodiversity of the urban park of the protected natural area.

In the contemporary economy the more and more greater role is played by state and local government institutions. Offices of public administration not only create law, but more and more often become initiators of the different type of investments undertaken on the ground of their jurisdiction. Often neighbouring administrative units begin to compete between themselves in gaining of investments and resources for the purpose of its own development. In the functionality of mentioned offices the greater role is performed by IT systems building the architecture of a given unit, clearly expressed among other things in the idea of intelligent city. Applied by offices of public administration IT systems are more often opened for suppliants creating e-government tools [1]. In this paper was presented the role of e-government tools in the business activation of the region on the basis of IT systems made available by Czestochowa Municipal Office. The review of potential directions of the e-government tools usage in different areas of social-economic life of the city will be presented

Using SWMM 5.1 (Storm Water Management Model) software, a model of sewage system functioning in Głogów was developed. It was calibrated based on the results of field studies from the years 2011– 14, while the properness of its activity was verified for the results of measurements carried out during the period 1998–2000. The verification of the model showed acceptable discrepancies between the measured and simulated values of channel depth. Factors which caused differences were indicated and, on the basis of this, conclusions pertaining to further studies were formulated.
