Water resources are the key factors affecting the sustainable development of inland river irrigation districts. The establishment of a water resources management model is helpful to realize the coordinated development of water, society, and ecology. Aiming at the contradiction of water use and ecological vulnerability, this study was based on the method of complex adaptive system (CAS) theory, and an agent-based modeling (ABM) method was adopted. Taking Huaitoutala irrigation district as the research object, a water resource management model considering ecological balance was established, with the water resources potentially tapping in the source area as an effective constraint. This study took 2016 as the datum year; the water consumption and comprehensive benefits of four water-saving irrigation scenarios in different characteristic years were simulated and optimized under the conditions of the current water supply and 10% and 15% potential water resources tapping. The results showed that the model considering the behavior and adaptability of the agent can well optimize and simulate the water use in the irrigation district. Under the application of water resources potential tapping and high-efficiency water-saving technology; the water utilization efficiency (WUE) of the irrigation area has been significantly improved. The comprehensive benefits of the irrigation district increased the proportion of ecological water, which was conducive to the sustainable development of the irrigation district and the ecological protection of inland rivers.

Based on complex adaptive system theory, the characteristics of water resources allocation system of river basin are analyzed. Evolutionary mechanisms and process of complex adaptive water resources allocation system in Dianchi basin are researched, and also characteristics of "learning". A complex adaptive system model of water-resource allocation is established during analyzing the influence factors and the reaction rules of water consumer agents and water provider agents. And based on this model, water resources in Dianchi basin is allocated only under Dianchi water provider and Zhangjiu river Yunlong reservoir water provider by using the platform of matlab. Finally, corresponding calculation results and conclusions are concluded.

No building or neighbourhood is an island but a constantly changing complex adaptive system produced by many contemporaneous, mostly interconnected and parallel but sometimes also conflicting processes. By using the development of Aalto University Campus, Finland, as an example of such a complex adaptive system in the course of change processes, the article demonstrates the challenge of transforming the production of our urban environment to truly meet the goals of sustainable development. Ecological sustainability is here understood as the need for regeneration, which is proposed as necessary in the current state of the planet. The article uses the concept of the perceived systemic environment and argues for its paradigmatic role in this context. Perceptions of the systemic environment affect and steer the actual goal setting of the stakeholders/actors in the system and can either enhance or even override the transition towards sustainability. The article suggests a way to steer the change towards a more regenerative perception of the systemic environment.

This review synthesizes diverse approaches that researchers have brought to bear on the challenge of sustainable development. We construct an integrated framework highlighting the union set of elements and relationships that those approaches have shown to be useful in explaining nature–society interactions in multiple contexts. Compelling evidence has accumulated that those interactions should be viewed as a globally interconnected, complex adaptive system in which heterogeneity, nonlinearity, and innovation play formative roles. The long-term evolution of that system cannot be predicted but can be understood and partially guided through dynamic interventions. Research has identified six capacities necessary to support such interventions in guiding development pathways toward sustainability. These are capacities to ( a) measure sustainable development, ( b) promote equity, ( c) adapt to shocks and surprises, ( d) transform the system into more sustainable development pathways, ( e) link knowledge with action, and ( f) devise governance arrangements that allow people to work together in exercising the other capacities.

It is of significance to examine the factors impacting individual water-saving behavior and their mechanism of action for water demand management, especially for domestic water demand management. To provide a solution to the issues of individual water-saving behavior research with unclear influence mechanisms and subjective modeling decisions, this study provides a novel idea of combining social survey and model study for research on domestic water conservation, introduces complex adaptive system theory to describe the mechanism of action between individuals as well as between individuals and external stimuli, and proposes a general framework for the model establishment and analysis of individual water-saving response research under external stimuli. This study uses Beijing as an empirical city. Based on the analysis results of the survey on Beijing residents’ domestic water use combined with the problems in Beijing’s domestic water-saving efforts, this study constructs water-saving regulation scenarios and corresponding individual water-saving response rules; systematically simulates the change process of individual water use considering the aspects of water price formulation, water use information, and water-saving publicity and education; quantitatively analyzes the influence of these three types of external stimuli on individual water saving; proposes individual water-saving promotion measures; and suggests the three aspects of water price formulation, water use information feedback, water-saving publicity and education.

Water Resources Utilization

Water is an important factor of production contributing to all sectors and regions in the world. With the rapid development of the economy and the increase of population, the water crisis is becoming more and more serious, and will become an important obstacle to the sustainable development of society. It is particularly important to evaluate the sustainability of water resources utilization. Based on the analysis of the regional water resources utilization characteristics, this paper takes 31 provinces in mainland China as the research object and comprehensively evaluates the regional water resources’ sustainability from the aspects of hydrology, environment, economy and technology. The results show: From the regional perspective, the regionalization of China’s various indexes is obvious, the hydrological and environmental indexes in western regions are significantly higher than that in eastern regions; while the economic index in eastern regions is higher than that in western regions. From the time perspective, from 2010 to 2015, the sustainable development of water resources in seven provinces showed an increasing trend. Zhejiang changed from “Good” to “Excellent” and Hubei, Hunan, Guangxi, Sichuan, Guizhou and Xinjiang all had slight growth. There are six provinces which show varying degrees of decline, of which Liaoning changes from “Excellent” to “Medium”, Beijing, Hebei, Jilin, Guangdong, Hainan also had a slight decline; the rest of the provinces did not change, Qinghai and Chongqing have been maintained as “Excellent”. Taken together, the western regions of China have significant advantages in terms of quantity and quality of water resources, but its water use efficiency is low. However, the economic development in the eastern regions is rapid with high efficiency of water use, but there are some serious problems such as water resources insufficiency and river pollution.
