BACKGROUND: Water is one of the basic materials of human existence. In respect this, many countries have been focused on water security agenda as one of the national strategic security. One of water security domains is coastal water security. Water security, due to the myriad of factors influencing water quantity and quality in coastal area, can be considered as a complex system. Due to the complexity and dynamic characteristic, system dynamic model (SDM) is needed to implement in coastal area to integrate all subsystem. AIM: This study aims to analyse the subsystems relating to coastal water security. The subsystem determination used to develop future policy-making relating to coastal water security. METHODS: For this purpose, a systematic literature review was conducted and a set of 12 papers was selected from 2009 – 2019. RESULTS: The papers’ analysis shows the applicability of SDM to solve complex problems. Water scarcity has been identified as a major problem in the coastal area, identified in eight papers. Three papers are related to water quality and only one paper relating to both. There are four major subsystems relating to coastal water security: environment, economic, social, and politic. Information about the aquaculture activities, the mechanism of coastal water pollution and water relating human health risk is still limited. CONCLUSION: We recommend use of SDM in the coastal water security to be extended to aquaculture, coastal water pollution and human health risk aspect in order to promote a holistic understanding of the complex issues and to develop more effective policies.

Frequent cyanobacterial blooms in eutrophic waters produce a variety of toxins such as microcystins (MCs), which are seriously harmful to waterbodies and human health.

<p>The present work proposes a novel screening tool to improve the quality of recreational coastal water. Indeed, the recreational potential of beach resort depends on its health status, which in marine cities may be threatened by increasing stress produced by anthropogenic activity. In particular, we focus on the beach near an estuary, which may be affected by a considerable load of contaminants, especially when the urban sewage system is combined and designed to spill untreated wastewater directly in the coastal water. In a few words, when the Combined Sewer Overflows (CSOs) are activated, the bacterial concentration in the estuary increases, thereby resulting in a potential hazard for the swimmers’ health. In the present work, the bacterial transport is modelled through a physically-based stochastic framework, whereas the human health risk is evaluated by means of the Quantitative Microbial Risk Assessment (QMRA). As the human health risk is quantified, it is used to evaluate the Carrying Capacity indicator of the recreational coastal water. This indicator is defined as the number of swimmers that can be sustained by coastal water with an acceptable risk threshold. The results indicate that the Carrying Capacity increases by dilution processes and by reduction of the source concentration. This indicator may be viewed as a screening tool for policy-makers and other stakeholders. For instance, it can help to balance the resources needed to improve the sewage-system and the benefits coming from tourism and sustainable environmental policies, given that the beach quality, in turn, depends on the improvements in the sewage system.</p>

Abstract Water pollution in China has not only become one of the most vital factors impeding the social-economic development but also threatening people's health. In this study, Kaifeng was considered as an example, and the human health risk of drinking water pathway from 2010 to 2017 was evaluated on the basis of drinking water hygiene standards and the human health risk assessment model (HHRA). Besides, the human health loss caused by water pollution was quantitatively evaluated through an emergy theory and analysis method. The results showed that the carcinogenic annual risk of carcinogenic pollutants ranged from 2.0 × 10−5 to 6.5 × 10−5, and the average health risk of non-carcinogenic pollutants was about 1.5 × 10−8, but the difference between different pollutants was obvious. Affected by water quality, social-economic development, Medicare, etc., the value of human health loss ranked at the top in 2016 with 8.73 × 1018 sej, equivalent to 9.33 million RMB, while in other years, it was around 6 × 1018 sej. It is indicated that among the factors, water quality is the direct inducement of healthy loss, the socio-economic development is the leading force effecting the value, and the Medicare is the final determinant of the public burden.
