The concern over ensuing freshwater scarcity has forced the developing countries to delve for alternative water resources. In this study, we examined the potential of stagnant surface water bodies (SSWBs) as alternative freshwater resources in the densely populated Chittagong metropolitan area (CMPA) of Bangladesh--where there is an acute shortage of urban freshwater supply. Water samples were ...

The importance of moisture feedback between continental precipitation and evaporation, referred to as moisture recycling, is still under debate. Most of the research in the past focused on the contribution of recycling to precipitation within a certain region only. This paper clearly distinguishes between different definitions of moisture recycling. This allows us to study the...

Freshwater flows have an important influence on the balance of fish species in estuaries. As well as supporting general ecosystem health, these flows are also necessary to comply with Australia-wide legislation aimed at the sustainable management of water resources. The Coastal Zone CRC and Fisheries Research and Development Corporation (FRDC) instigated the ‘environmental flows for estuaries’ ...

The impact of water use in areas with abundant freshwater resources should not be the same as areas with limited resources. This impact is quantified as water scarcity footprint. The monthly water stress index with reference to environmental water requirement is proposed as a characterization factor. The biofuel policies of Thailand—cassava and sugarcane for bioethanol, and oil palm for biodies...

Liquid and solid precipitation is abundant in the high elevation, upper reach of the Heihe River basin in northwestern China. The development of modern irrigation schemes in the middle reach of the basin is taking up an increasing share of fresh water resources, endangering the oasis and traditional irrigation systems in the lower reach. In this study, the response of vegetation in the Ejina Oa...

A major challenge for the 21 st century will be the efficient use of all resources to minimize wastage. Lack of fresh water is becoming one of the largest and most universal of the resource problems that we face in the new century. This leads us to consider the options for turning wastewaters into useful resources, with recovery of the water for reuse. Therefore, wastewater has become an essent...

climate change phenomenon is an important environmental challenge of the world. increasing extension of greenhouse gases and remote relationship phenomena accelerate the speed f climate change. changes in precipitation level, drought occurrence and changes in the level of surface and groundwater resources are the recognized consequences of climate change. in order to study consequences of clima...

climate change phenomenon is an important environmental challenge of the world that has increased its speed with the increasing extension of greenhouse gases and remote relationship phenomena. changes in precipitation level, drought occurrence and in the level of surface and groundwater resources are the recognized consequences of climate change. in order to study climate change phenomenon cons...

in this study, postharvest characteristics of eight cut rose cultivars (valentine, king pride, prima donna, black baccara, victory, papagayo, royal baccara and yellow island) were investigated in a growth room with temperature of 20 ºc, relative humidity of 50% and light intensity of 10 µmol m-2 s-1 in autumn 2008. among cultivars significant differences were found for all of the attributes eva...
