Established by the U.N. Brundtland Commission in Our Common Future three decades ago, sustainable development has increasingly far-reaching influence on all aspect of our lives. Sustainability has close connection with the balance of ecosystem, and it is also about industries and businesses. Water, as a valuable and scarce resource, is necessary for our socio-economic activities. Since over-exploitation and water pollution have generated huge environmental cost for socio-economic systems (Yang et al., 1774), water quality and water crisis are no longer strange to everyday people. A successful transition to a sustainable economy requires proper water resource conservation and management, therefore maintaining good water quality and sustainable water supplies are two of the pressing issues that must be faced.
Water quality is largely a physical, chemical and biological concern, which is described based on the suitability of water ( Cordy, 2001). Various selected characteristics are compared to numeric standards and guideline established to protect water for designated uses ( Cordy, 2001). The quality of natural water, broadly divided into ground water and surface water, varies from different landscapes, with the seasons, and with human interference. Urban and industrial development, agricultural activities, stream-channel alteration, combustion of fossil fuels, and other human activities can affect the quality of natural waters (Winter et al., 1998). For example, the application of chemical fertilizers will have long-lasting impact on aquatic ecosystems because of the transport and fate of contaminants caused by those unsustainable agricultural practices (Winter et al., 1998). Apart from natural waters, human activities including production and consumption have negative impact on water quality in both urban and rural water bodies such as inner lakes and rivers. One of the prominent problem associated with this issue is the reuse of polluted water which is considered as a promising method of extending the value of limited water resource. As high quality water allows for more uses than low quality water (Berger and Finkbeiner, 2010), the most efficient way to guarantee water quality is to manage renewable water reserves and the discharge of used water wisely. In addition to proper physical disposal and management of water use, according to Winter et al, the tendency of chemical contaminants moving among water bodies is another principal area in managing water resources, especially in protecting the quality of drinking water. Further improved scientific understanding and discover of the interconnections between those exchanging processes will be of beneficial to remedying contaminated water resources, to evaluating proper methods and applications for waste-discharge permits, and to protecting and restoring biological resources (Winter et al, 1998).
Another pressing issue related to water resource is water scarcity, which is identified by the World Economic Forum as “water crises”, one of the top 10 issues of greatest concern to the global economy in 2014 (Wong, 2014). One of the major causes for this problem is the inexorable population growth, which exacerbates the stress of water scarcity already placed on many regions where the demands of agriculture, energy and industry all require abundant and clean water for production (Wong, 2014). However, the nature of the systems surrounding water makes it more difficult to come up with a singular solution. As Wong (2014) pointed out that the web of water generation and consumption - the ecosystems which preserve and replenish freshwater in natural environment, the political systems responsible for allocating the scarce resource and the various ways of consuming water for agriculture, drinking and production - creates a complex context for water scarcity issue.
Due to this complexity, the extent of the mitigation of water scarcity should yield better results with collaboration on systematic level solutions, involving applied policies or technologies and the subsidies granted to promote policy or technology implementation (Berger and Finkbeiner, 2010). No only the public sector will invest resources to find better solutions to water scarcity problem, the momentum driven by private sector is also of great importance with their increasing understanding and positive actions on water crisis. The quick development of water markets, which focus on water rights and water quality trading, can deploy water resource toward the most economically sensible solutions and deliver promising results (Wong, 2014).
Water quality and scarcity problems have long been the center of discussion on sustainability topics and myriad of researches have devoted time and energy into water challenges that we face today. Although effective methods and policies related have been put forward and applied in order to improve the water quality, water scarcity problem will become only more pressing and affect billions more people each passing year. Water scarcity challenge can have enormous impact on socio-economic status of an area, especially in those suffering from poverty and worrying healthcare condition. To meet the challenge of increasing population and economic development, more attention and resources should be allocated to solving these pressing sustainability issues.
