The geographical location of Bangladesh is gifted with enormous natural recourse: water, alluvial land,suitable climatic conditions for bio diversity and other natural assets. The capital, Dhaka, surroundedby rivers on four sides, was once a blue-green-built environment offering a healthy living atmosphere forits habitants. The city was dotted with huge and crisscrossed water bodies, a tolerable population density,and enough open spaces. Urban and peri-urban areas of the city complemented its food demand whichsubsequently maintained the environmental equilibrium. The modern concept of eco-urban-agriculture willdefinitely be beneficial in such a dense city which is rapidly losing its livability by insensitive urbanization.This paper will describe how a city could generate food, improve health, and utilize waste by furthering theestablished urban-agriculture concept. It aims to develop an understanding of this concept in Bangladesh,particularly in the dense urban fabric of Dhaka, by discussing the theoretical background of urban agricultureand practiced models of eco-urban-agriculture in urban settings around the world.

The key anthropogenic effects on climate include the changes in land use and emission of greenhouse gases into the atmosphere. Depletion of vegetation poses serious threat that speeds the process of climate change and reduces carbon sequestration by the environment. Thus, the preservation of natural environment in urban areas is an essential component of the garden city model, proposed by Sir Ebenezer Howard in 1898, to ensure ecological balance. Recent Landsat images showed that Kumasi does not have the required percentage of green vegetation as was stipulated in the garden city model on which the city was built. It was observed that most parts of Kumasi's green vegetation have been lost to built environments. This study was conducted to assess the impact of urbanization on the garden city status and its effect on the micro-climate of the city. Significant changes in the vegetation cover of the city was evaluated from Landsat-TM imagery and analysis of a long term climatic data of Kumasi carried out over a 55-year period (1960 to 2015). It was observed that, climatic conditions have slightly changed, as mean surface temperature of has increased by 1.2 °C/ 55 years, due to the significant landuse changes from development of non-transpiring, reduced evaporative urban surfaces. However, the impact is not greatly felt due to the geographical location of the city on the globe despite the evidence of a considerable temperature change. Green vegetation conservation for the city is recommended as a top priority in future for city authorities and planners.

The emergence of the modern concept of the sustainable city raises afresh the longstanding issue of the place and role of vegetation in urban and peri-urban areas in Europe. The awareness of biodiversity and the exploration of the services provided by ecosystems both lead to the development of ecological networks based on green spaces in and around the city. The establishment of these networks converges with the control of urban growth and urban sprawl, with the ‘green belts’. Drawing on the development of public policy governing the place of vegetation in Berlin, London and Paris, this article seeks to show the correspondences that have developed in the discussions of urban policy carried on in the major industrialized countries, and also the conflicting goals which these policies are meant to implement.

Trees are essential elements of an urban space. The presence of trees in urban areas is not only appreciated as physical attribute, but beyond this, it serves a fundamental function in balancing and conserving urban ecosystem. Especially in tropical countries like Indonesia which receive high levels of solar radiation, trees contribute to the protection of urban areas from the impact of excessive micro-climatic conditions. But, the presence of trees sometimes resulted in the accidents for the residences because of broken branches and human injuries. This situation leads the city to prepare a tree inventory system, which is beneficial in giving the information about tree conditions and thus the information that would be useful for tree maintenance activities. The tree inventory on application for the city of East Jakarta was built for this purpose, comprising a tree inventory and easy access to the database. The application connects the database source with the GIS map, so that the users could retrieve information for each kind of data.

The spatial visualization is a very useful tool to help decision-makers in the urban planning process to create future energy transition strategies, implementing energy efficiency and renewable energy technologies in the context of sustainable cities. Statistical methods are often used to understand the driving parameters of energy consumption but rarely used to evaluate future urban renovation scenarios. Simulating whole cities using energy demand softwares can be very extensive in terms of computer resources and data collection. A new methodology, using city archetypes is proposed, here, to simulate the energy consumption of urban areas including urban energy planning scenarios. The objective of this paper is to present an innovative solution for the computation and visualization of energy saving at the city scale.The energy demand of cities, as well as the micro-climatic conditions, are calculated by using a simplified 3D model designed as function of the city urban geometrical and physical characteristics. Data are extracted from a GIS database that was used in a previous study. In this paper, we showed how the number of buildings to be simulated can be drastically reduced without affecting the accuracy of the results. This model is then used to evaluate the influence of two set of renovation solutions. The energy consumption are then integrated back in the GIS to identify the areas in the city where refurbishment works are needed more rapidly. The city of Settimo Torinese (Italy) is used as a demonstrator for the proposed methodology, which can be applied to all cities worldwide with limited amount of information.

The application of multi-floor manufacturing (MFM) in huge cities is related to the rational use of urban areas and the solution to traffic problems. The operation of the city MFM clusters depends on the efficiency of production and transport management considering technical, economic, environmental, and other factors. The primary goal of this paper was to identify and analyze the drivers of sustainable supply chains (SSCs) that influence or encourage the design of sustainable processes in city MFM clusters under uncertainty in supply chains. This paper presents an SSC performance model for city MFM clusters under uncertainty. The proposed model is universal and is based on material flow analysis (MFA) methodology. The presented analysis helps to determine the conditions for rhythmic deliveries with the use of the multi-IRTs. The coefficients of rhythmic deliveries for multiple intelligent reconfigurable trolleys (IRTs) and the capacity loss of freight elevators allow us to periodically assess the sustainability processes in city MFM clusters related to the flow materials. These assessments are the basis for the decision-making and planning of SSCs.

Abstract Using ‘Urban Atlas’ as a data source, the authors present and critically discuss in this paper the application of figure-ground plans in combination with complex land-use maps as a tool for spatial analysis of urban agriculture in European cities and their multifunctional green infrastructure. The selected cities and metropolitan areas (including Dublin, Ruhr Metropolis, Geneva and Sofia) represent different regions in Europe from the Northwest to the Southeast. Urban fabric, agriculture and non-agricultural open spaces have been analysed and compared as the main land-use components. Agricultural open spaces include arable land with annual crops and permanent crops, such as vineyards, fruit trees and olive groves; pastures; as well as complex and mixed cultivation patterns. The results reveal the scale and land-use diversity of metropolitan regions and different spatial patterns of urban agriculture at the regional level and in central urban areas.

Agribusiness may potentially develop on Palu Riversides. This research aims to formulate a sustainable agricultural spatial innovation for the Development of Agribusiness Places on Palu Riversides. The methods used for this study were field observation, satellite image map observation, and literature review. The results showed that the implementation of sustainable agriculture through the development of agribusiness places in urban areas could take advantage of the open spaces designated as green open space zone on the Palu Riversides, namely the River Green Area which is outside the riparian zone, the river overflow runoff area. To achieve this objective, it requires ability to innovate in spatial planning so that an urban agricultural area that is neatly arranged into an agribusiness places can also be developed into one of the city landmark.

<p>The renovation of the waterfronts, such as those in the main public spaces of large cities, started in 1970s. Core industries had found other places to develop far from the city; thereafter key areas fell out of use and into disrepair. As a consequence, a huge number of urban areas became in urgent need of renewal. However, urban design guidelines to regenerate these open spaces have significantly changed since then. The approach towards returning these parts of the city to its inhabitants has evolved from an emphasis on building new housing in the nineties, to considering the broader aspects of sustainability in the early years of the current century and finally to searching for the areas’ identity in more recent years. Therefore, currently this identity is one of the main aspects designers are looking for. At the same time, the sustainability of the waterfront areas may be achieved through the establishment of this place´s sense of identity. In order to do this, we assess three urban actions undertaken in Portland and Vancouver -False Creek North, South Waterfront and Southeast False Creek-. The article suggests that the interplay between urban design, sustainability and identity is becoming the new driver for the design of the waterfronts.</p>

The advantages of urban and peri-urban agriculture in West African cities, namely its contribution to food production, income generation and resorbing unemployment are well reported. In the peri-urban areas, cropping systems and practices are various and may affect differently soil properties. Those systems and practices may be driven by farms socio-economic conditions. Here we conducted a study in 133 peri-urban farms located at the vicinity of the city of Ouagadougou. Farmers were questioned on their cropping practices and soil samples were taken and analyzed for their total organic C, available P and K contents. Principal component analysis allowed to study the variability of the farms considering cropping systems, the cropping practices and the farms socio-economic conditions. We found that in the studied cropping systems up to 60% of the farms variability was explained. Monoculture led to low soil organic carbon while polyculture led to low soil available K. The studied socio-economic conditions of the farms explained up to 60% of the variability in cropping practices.
