Analysis and predication of urban water security: a case study of Chengdu City, China

Assessment of Regional Water Resource Security: A Case Study from Hebei Province, China

“…Taking Luoyang City in China for example, Dong constructed an evaluation index system of water resource safety based on the pressurestate-response framework, determined the index weights following the analytic hierarchy process and using the entropy weight method, and introduced the water resource indexes from 2006 to 2016 into the set to evaluate the analysis model [10]. To analyse the sustainable status of water resources, Chen and Shi used the pressure-stateresponse model to construct a water safety index system, calculated the index weights through the Analytic Hierarchy Process (AHP), conducted a comprehensive evaluation of the urban water safety status in this city using the water resource safety indexes from 2005 to 2013, and proposed relevant measures for strengthening the water environment and the water resource safety capacity based on the evaluation results [11]. Zhang combined the ecological network analysis method and the input-out model to analyse the water use structure and the interactive control relationship between departments in an urban ecosystem and found that the industries with the greatest influence on the urban water resource state are machinery manufacturing and the food and tobacco processing industry [12].…”

Urban water security - what does it mean?

“…Two earlier water security definitions (Wutich and Ragsdale 2008;Hao, Du, and Gao 2012) had been applied in the urban context, but the definitions proposed were general. Only three definitions specific to urban water security have been identified as part of this study (see Table 3), all in the academic literature, with two focussed on 'capacity' and 'sustainability' (Chen and Shi 2016; Romero-Lankao and Gnatz 2016) and a third focused on 'access, safety, and affordability' and 'psychological' security (Huang, Xu, and Yin 2015).…”

“…(Huang, Xu, and Yin 2015) Urban water security is regarded as the capacity for sustainable development of the city under the influence of water resources, which could ensure the development of society, economy, ecological environment, citizens and humanistic environment. (Chen and Shi 2016) Urban water security is the capacity of urban water actors to maintain a sustainable availability of adequate quantities and quality of water, to foster resilient urban communities and ecosystems in the face of uncertain global change.…”

An Assessment of Temporal and Spatial Dynamics of Regional Water Resources Security in the DPSIR Framework in Jiangxi Province, China

“…The DPSIR framework has been widely applied in water resources and ecological security assessment studies [ 19 , 24 , 25 , 26 , 27 , 28 , 29 , 30 , 31 , 32 , 33 , 34 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 , 44 ]. Some primitive versions and new variants of the DPSIR framework were also used in the literature, e.g., PSR model [ 45 , 46 ], DPSI model [ 33 ], PSIR model [ 47 , 48 ], DPSR model [ 49 ], and DPSIRM model [ 36 , 50 ].…”

“…Water resources shortage, drought, and flood disasters and water ecological environment problems have become important factors restricting China’s economic development. Water resources security evaluation has received significant interests among scholars [ 7 , 16 , 20 , 27 , 30 , 36 , 45 , 54 , 55 , 56 , 57 , 58 , 59 , 60 ]. Regional water resources security evaluation has been done at both river basins [ 37 , 43 , 44 , 61 , 62 , 63 ] and urban areas which are analyzed both at the level of individual cities [ 15 , 41 , 45 , 46 , 58 , 64 , 65 ] and at the level of provinces [ 16 , 20 , 27 , 47 , 54 , 56 , 65 , 66 , 67 , 68 ].…”
