    From traditional to modern water management systems; reflection on the evolution of a ‘water ethic’ in semi-arid Morocco

    Get PDF
    The chapter focuses on water because of the crucial importance of that resource in a semiarid country and because the ways in which it has been managed throughout centuries illustrate the changes in socio-political structures in the society. The focus on water in a semi arid country is symbolic of how precious natural resources are in the development of economies and societies. Morocco provides a fascinating terrain to explore ingenuous traditional water management structures and processes both in urban and in rural environments

    This is a collection of evidence-based papers by scholars and practitioners that explore the interconnections between gender equality and sustainable development across a range of sectors and global development issues such as energy, health, education, food security, climate change, human rights, consumption and production patterns, and urbanization. The publication provides evidence from various sectors and regions on how women's equal access and control over resources not only improves the lives of individuals, families and nations, but also helps ensure the sustainability of the environment

    Visual communication in urban planning and urban design

    This report documents the current status of visual communication in urban design and planning. Visual communication is examined through discussion of standalone and network media, specifically concentrating on visualisation on the World Wide Web(WWW).Firstly, we examine the use of Solid and Geometric Modelling for visualising urban planning and urban design. This report documents and compares examples of the use of Virtual Reality Modelling Language (VRML) and proprietary WWW based Virtual Reality modelling software. Examples include the modelling of Bath and Glasgow using both VRML 1.0 and 2.0. A review is carried out on the use of Virtual Worldsand their role in visualising urban form within multi-user environments. The use of Virtual Worlds is developed into a case study of the possibilities and limitations of Virtual Internet Design Arenas (ViDAs), an initiative undertaken at the Centre for Advanced Spatial Analysis, University College London. The use of Virtual Worlds and their development towards ViDAs is seen as one of the most important developments in visual communication for urban planning and urban design since the development plan.Secondly, photorealistic media in the process of communicating plans is examined.The process of creating photorealistic media is documented, examples of the Virtual Streetscape and Wired Whitehall Virtual Urban Interface System are provided. The conclusion is drawn that although the use of photo-realistic media on the WWW provides a way to visually communicate planning information, its use is limited. The merging of photorealistic media and solid geometric modelling is reviewed in the creation of Augmented Reality. Augmented Reality is seen to provide an important step forward in the ability to quickly and easily visualise urban planning and urban design information.Thirdly, the role of visual communication of planning data through GIS is examined interms of desktop, three dimensional and Internet based GIS systems. The evolution to Internet GIS is seen as a critical component in the development of virtual cities which will allow urban planners and urban designers to visualise and model the complexity of the built environment in networked virtual reality.Finally a viewpoint is put forward of the Virtual City, linking Internet GIS with photorealistic multi-user Virtual Worlds. At present there are constraints on how far virtual cities can be developed, but a view is provided on how these networked virtual worlds are developing to aid visual communication in urban planning and urban design

    State of the world’s cities 2012/2013

    This report by the UN looks into the prosperity and the changing urban landscape of major cities all around the globe. As the world moves into the urban age, the dynamism and intense vitality of cities become even more prominent. A fresh future is taking shape, with urban areas around the world becoming not just the dominant form of habitat for humankind, but also the engine-rooms of human development as a whole. This ongoing evolution can be seen as yet another assertion, albeit on a larger scale, of the time-honoured role of cities as centres of prosperity. In the 21st as in much earlier centuries, people congregate in cities to realize aspirations and dreams, fulfil needs and turn ideas into realities. Prosperity in this broader, organic sense transcends narrow economic success to encompass a socially broadbased, balanced and resilient type of development that combines tangible and more intangible aspects. Taken in this multi-dimensional sense, urban prosperity tightens the links between individuals and society with their everyday environment, i.e., the city itself. Amidst multiple challenges facing cities today, a focus on poverty reduction and/or responses to the economic crisis is gradually shifting to a broader and more general understanding of the need to harness the transformative dynamics and potentials which, to varying degrees, characterize any city anywhere in the world

    Environmental Law, Governance, and Management- the Need for Environmental Management Systems for Cities

    Get PDF
    Human activities damage the environment. They deplete natural resources, generate pollution and wastes, accelerate the loss of forests and biological diversity, as well as threaten the water supply. As populations increase, these problems are exacerbated. Cities bear the brunt of increased human activities on limited land space with limited resources. It is therefore essential that cities adopt a system of environmental governance that will help ensure sustainability. As each city has its own mix of geographic, social, economic, political and environmental problems, it would be simplistic to suggest that there is a formula for sustainability that would fit every city. What is clear is that every city needs an effective environmental management system (EMS) to manage its many activities, to ensure that development is controlled, environmental damage is minimized, natural areas are preserved and its citizens have an enhanced quality of life. This paper examines the ingredients for sound environmental management in cities, particularly cities in the developing world. It submits that a sound EMS for a city must first start with sound environmental policies, land use planning and good environmental laws. It emphasizes that the best environmental laws will not work if it is not integrated with sound management policies and implementation, starting with the building of the environmental infrastructure, both physical and institutional. This paper then looks at ISO 14001 certification, in the context of a city and asserts that environmental management systems in their current context, focus largely on resolving problems of pollution. There is a clear lack of ecological dimensions in environmental management systems as exemplified by the ISO 14000 series. This paper submits that environmental stewardship and ecological sustainability is at the heart of sustainable development, and the integration of the natural environment within the city has been largely overlooked. It advocates bringing the natural environment back to our cities and the incorporation of this dimension into environmental management systems. The paper introduces the Singapore Index on Cities\u27 Biodiversity, adopted at the CBD\u27s COP-10 Meeting in Nagoya, Japan, 2010

    Post-Westgate SWAT : C4ISTAR Architectural Framework for Autonomous Network Integrated Multifaceted Warfighting Solutions Version 1.0 : A Peer-Reviewed Monograph

    Full text link
    Police SWAT teams and Military Special Forces face mounting pressure and challenges from adversaries that can only be resolved by way of ever more sophisticated inputs into tactical operations. Lethal Autonomy provides constrained military/security forces with a viable option, but only if implementation has got proper empirically supported foundations. Autonomous weapon systems can be designed and developed to conduct ground, air and naval operations. This monograph offers some insights into the challenges of developing legal, reliable and ethical forms of autonomous weapons, that address the gap between Police or Law Enforcement and Military operations that is growing exponentially small. National adversaries are today in many instances hybrid threats, that manifest criminal and military traits, these often require deployment of hybrid-capability autonomous weapons imbued with the capability to taken on both Military and/or Security objectives. The Westgate Terrorist Attack of 21st September 2013 in the Westlands suburb of Nairobi, Kenya is a very clear manifestation of the hybrid combat scenario that required military response and police investigations against a fighting cell of the Somalia based globally networked Al Shabaab terrorist group.Comment: 52 pages, 6 Figures, over 40 references, reviewed by a reade
