“…While useful in many regards, this approach addresses the physical water sector in isolation and social factors are generally considered as exogenous inputs, thus neglecting the dynamic interaction and feedback between physical and social processes (Giacomoni et al 2013). As a result, it is argued that current water management is insensitive to social values and hence social drivers were not incorporated into management decision in a systematic way (Rammel et al 2007;Pahl-Wostl et al 2008).…”

Evolution of newspaper coverage of water issues in Australia during 1843–2011

News accounts both reflect and influence public opinion through their noted 'agenda-setting' capability. We examined newspaper articles in Australia's The Sydney Morning Herald from 1843 to 2011 to observe the evolution of media coverage on water issues related to water resources management. The results showed that water supply-related articles have dominated the reporting of water issues since 1843. This emphasis is reflected in the institutions involved and their related policy/management initiatives, as well as the themes of the articles. Extreme events such as flooding and drought have punctuated the historical record of reports on water issues. An economic development-driven tone was overwhelmingly predominant in newspaper articles (85 % of the total); however, there has been a marked decline in the importance of development-driven tone relative to environmental-sustainability oriented tone of articles since 1994. People from academia and NGOs were rarely quoted. Inclusion of wider range stakeholders should be considered as a strategic break-through and natural events should be considered as an ''opportunity'' to change public opinion on water issues for environmental sustainability.

“…A stage-1 outdoor water use restriction specifies that lawn watering should be reduced to twice per week; a stage-2 outdoor water use restriction specified that lawn watering should be reduced to once per week; and a stage-3 restriction bans lawn watering altogether. Equation (9) ensures that consumer demand will be met during the simulation period. The constraint represented by Equation (10) ensures that the instream flow requirement is maintained year round, even during severe drought.…”

“…Several studies of urban water management used ABM approaches and focused primarily on demand-side management through pricing [27,28] and non-pricing [2,[29][30][31] conservation measures; none of these studies, however, incorporated supply-side decisions. Giacomoni et al [9] developed an ABM framework to simulate the dynamics of land use change, population growth, and adaptations of water demands and the effects on water sustainability. The framework was applied to simulate alternative demand-side management strategies, including outdoor watering restrictions, a rainwater harvesting rebate program, and a high-density land-use change policy [32].…”

“…The CAS modeling framework was developed to simulate urban water resources [9,10] and is extended in this research to explore the sustainability of using demand-side and supply-side management for water resources through a multi-objective approach. The CAS framework is coupled with an evolutionary computation-based multi-objective optimization methodology, the non-dominated sorting genetic algorithm II (NSGA-II) [11].…”

Abstract:Urban water supply systems may be managed through supply-side and demand-side strategies, which focus on water source expansion and demand reductions, respectively. Supply-side strategies bear infrastructure and energy costs, while demand-side strategies bear costs of implementation and inconvenience to consumers. To evaluate the performance of demand-side strategies, the participation and water use adaptations of consumers should be simulated. In this study, a Complex Adaptive Systems (CAS) framework is developed to simulate consumer agents that change their consumption to affect the withdrawal from the water supply system, which, in turn influences operational policies and long-term resource planning. Agent-based models are encoded to represent consumers and a policy maker agent and are coupled with water resources system simulation models. The CAS framework is coupled with an evolutionary computation-based multi-objective methodology to explore tradeoffs in cost, inconvenience to consumers, and environmental impacts for both supply-side and demand-side strategies. Decisions are identified to specify storage levels in a reservoir that trigger: (1) increases in the volume of water pumped through inter-basin transfers from an external reservoir; and (2) drought stages, which restrict the volume of water that is allowed for residential outdoor uses. The proposed methodology is demonstrated for Arlington, Texas, water supply system to identify non-dominated strategies for an historic drought decade. Results demonstrate that pumping costs associated with maximizing

While urbanization brings economic and social benefits, it also causes water pollution and other environmental ecological problems. This paper provides a theoretical framework to quantitatively analyze the dynamic relationship between water resource utilization and the process of urbanization. Using data from Jiangsu province, we first construct indices to evaluate urbanization and water resource utilization. We then adopt an entropy model to examine the correlation between urbanization and water resource utilization. In addition, we introduce a dynamic coupling model to analyze and predict the coupling degree between urbanization and water resource utilization. Our analyses show that pairing with rising urbanization during 2002-2014, the overall index of water resource utilization in Jiangsu province has experienced a "decline -rise-decline" trend. Specifically, after the index of water resource utilization reached its lowest point in 2004, it gradually began to rise. Water resource utilization reached its highest value in 2010. The coupling degree between urbanization and water resource utilization was relatively low in 2002 and 2003 varying between −90 • and 0 • . It has been rising since then. Out-of-sample forecasts indicate that the coupling degree will reach its highest value of 74.799 • in 2016, then will start to gradually decline. Jiangsu province was chosen as our studied area because it is one of the selected pilot provinces for China's economic reform and social development. The analysis of the relationship between provincial water resource utilization and urbanization is essential to the understanding of the dynamic relationship between these two systems. It also serves as an important input for developing national policies for sustainable urbanization and water resource management.
