The paper explores Dar es Salaam, a rapidly expanding city in Sub-Saharan Africa, and shows that urban agriculture provides urban ecosystem services and contributes to environmental sustainability. The interconnections of environmental justice, urban ecosystem services and climate change and variability found eminent feature that influence land governance, productivity and aesthetic value of the city. The study reaffirms the pivotal role urban agriculture which plays to enhance community health services and access to resources, with important implications on urban environmental sustainability and redistributive spatial land use planning policies and practices. The process of urbanisation, forms of urban agriculture and government strategies for enhanced urban food systems in the city economy have been highlighted. Equally, the process triggers the transformation of settlements from rural in character to modernity with an augmented land use conflicts. The results suggests that with increasing population, a clear spatial land use planning and management strategy is required to overcome the challenges and enhanced food systems and urban environmental sustainability in rapidly urbanizing cities like Dar es Salaam in Sub-Saharan Africa.展开更多
Proper architectural design and appropriate usage of technology compatible with the environment in parts of a city which is called urban spaces, spaces such as parks, squares, sidewalks, shopping malls, leave a great ...Proper architectural design and appropriate usage of technology compatible with the environment in parts of a city which is called urban spaces, spaces such as parks, squares, sidewalks, shopping malls, leave a great impact on the quality of the urban life. Architectural design itself is born from technology;it means that, architecture is tied with science and technology, and is in direct contact with them. Technological innovations are one of the most important forces affecting the architectural changes. Nowadays, technological innovations are recognized as important and effective powers in development of sustainable environmental design. Today societies are constantly changing in terms of social, economic, political and technological alterations. Change is inevitable, and like all aspects of contemporary life, architecture should similarly offer an appropriate response to such changes for remaining sustainable, useful and appropriate. Architecture should also have a suitable response to laws and regulations of recent issues like safety, environment and energy conservation, and even personal security in architectural space. The purpose of this paper is, primarily an exploration of the concept of “urban space”, and in the second stage, it plans to review the fundamentals and impacts of using technology in urban spaces. The research method is descriptive-analytic and library research method is used for data collecting.展开更多
