Nearly 3 billion additional urban dwellers are forecasted by 2050, an unprecedented wave of urban growth. While cities struggle to provide water to these new residents, they will also face equally unprecedented hydrologic changes due to global climate change. Here we use a detailed hydrologic model, demographic projections, and climate change scenarios to estimate per-capita water availability ...

In response to the facts that some Asian developing countries were experiencing the fastest rate of industrialisation and urbanisation, several international initiatives called for a better and ‘sustainable’ urban management. Development of management tools including strategic environmental assessment (SEA), life cycle assessment (LCA), cost benefit analysis (CBA), and environmental managemen...

Precisely management of water quality in urban rivers is of significant and water environmental capacity provide a useful tool. This study presented a water quality analysis simulation program model-based approach for dynamical load reduction in Ashi River, highly contaminated tributaries of Songhua River, China. The actual and surplus dynamic environmental capacity of CODCr and NH<s...

tehran has been facing water shortage challenge for decades and it has not hesitated to exploit neighboring watersheds. rising demand and limited resources might make water crisis a strong possibility in the near future. an accurate and applied analysis of tehran&apos;s urban water system (uws) would be the first step to be taken to prevent such a crisis. this research is an effort to make an a...

Disasters and climate change impacts, as well as increased water demand, pose serious risks to the provision of sustainable urban water services, e.g., drinking water, sanitation, and safe drainage, especially in cities. These challenges call for a transition toward improved water management, including considerations of “resilience.” However, because the resilience concept has multidisciplinary...

Innovative ways to manage the urban water cycle are required to deal with an ageing drinking and waste water infrastructure and new societal imperatives. This paper examines the influence of water governance in enabling transformations and technological innovation uptake in urban water management. A governance assessment framework is developed and applied in three case-studies, examining differ...

A survey of the microbiological and chemical quality of water supplies in the Bindura urban and peri-urban area was carried out over a three year period from January 2000 to July 2003. Bindura is the provincial city of Mashonaland Central, situated 88 km from the national capital, Harare. Large-scale farming and mining activities in the area predispose water bodies to eutrophication and chemica...

The problem of mixed pixels negatively affects the delineation of accurate surface water in Landsat Imagery. Linear spectral unmixing has been demonstrated to be a powerful technique for extracting surface materials at a sub-pixel scale. Therefore, in this paper, we propose an innovative low albedo fraction (LAF) method based on the idea of unconstrained linear spectral unmixing. The LAF stands...

While URGE, GreenKeys, and SWITCH are already completed, CyberParks is in its initial steps. The projects URGE and GreenKeys focus on green landscapes. In URGE, a set of criteria was created to assess urban green spaces, and thus increase their potential for improving the quality of life in cities. GreenKeys addressed the creation and adoption of green space strategies as a shared vision toward...
