Abstract. Water is an essential input to the majority of human activities. Often, access to sufficient water resources is limited by quality and infrastructure aspects, rather than by resource availability alone, and each activity has different requirements regarding the nature of these aspects. This paper develops an integrated approach to assess the adequacy of water resources for the three major water users: the domestic, agricultural and industrial sectors. Additionally, we include environmental water requirements. We first outline the main determinants of water adequacy for each sector. Subsequently, we present an integrated approach using fuzzy logic, which allows assessing sector-specific as well as overall water adequacy. We implement the approach in two case study settings to exemplify the main features of the approach. Using results from two climate models and two forcing RCPs (representative concentration pathways), as well as population projections, we further assess the impacts of climate change in combination with population growth on the adequacy of water resources. The results provide an important step forward in determining the most relevant factors, impeding adequate access to water, which remains an important challenge in many regions of the world. The methodology allows one to directly identify the factors that are most decisive in determining the adequacy of water in each region, pointing towards the most efficient intervention points to improve conditions. Our findings underline the fact that, in addition to water volumes, water quality is a limitation for all sectors and, especially for the environmental sector, high levels of pollution are a threat to water adequacy.

Entropy Weight

Abstract Scientific assessment provides important tools for the sustainable use of water resources. This paper applies the set pair theory of entropy weight to evaluate the uncertainty involved. A preliminary classification of samples is conducted by calculating the connection degree of each evaluation index, and then uniform, differential and confrontational analyses of set pairs are carried out on the samples to identify their level. In identifying the weight of each evaluation index, the entropy value theory of information theory is introduced into the model. Combined with Tarim 2004 to 2007 water resource data, an evaluation of the sustainable water resource utilization in this region is made from the social and economic, water resource and ecological environmental water resource evaluation index system. The results show that the development and utilization of water resources in the Sanyuanliu region of Tarim are saturated, and the utilization of water resources in the Hotan region (III), Aksu region (III) and Kashgar region (III) appears to be unsustainable. After a comparison with other methods, it is concluded that the evaluation result provided by the method is reasonable and objective.

A sustainability assessment of water resources is essential for maintaining regional sustainable development. In this study, a comprehensive assessment of changes in the sustainability of the water resource system in Beijing from 2008 to 2018 was conducted on the basis of the driver-pressure-state-impact-response (DPSIR) model. To reflect the impacts of humans on the water consumption and pollution of water resources, the water footprint was considered. In addition, key factors that affect the sustainability of water resources were filtered by the modified entropy method. The results indicated that all drivers, pressures, states, impacts, and responses demonstrated increasing tendencies. As a result, a remarkable improvement in the sustainability of the water system, which was mitigated from an alert state to a good state, was achieved due to the comprehensive effect of the indexes. From these results, we inferred that the sustainability of regional water resources could only be achieved through a comprehensive consideration of regional social, economic, and environmental water systems and climate change. Therefore, formulating medium- and long-term urban, economic, and water development plans and adjusting medium- and short-term water utilization programs could contribute to the sustainable utilization of regional water resources.

Water Quality And Quantity

Abstract It is difficult to simultaneously manage the dynamic demands for river water quality and quantity, and reconcile the contradiction between socio-economic and eco-environmental water consumption. As a solution, we proposed a three-tier model to optimize the distribution of river water resources. Using three constraint conditions, namely the ratio of wastewater to clean water, the eco-environmental water requirements of each node and the use of wetland projects, we determined various water quantity and quality allocation scenarios. We tested the model on the Qingyi River, and found that, for the recommended scenario that involved enhanced water-saving, a wastewater/clean water ratio and wetlands, more than 80% of the eco-environmental water requirements of each node except for the Luma section were achieved for each month. While the water quality in some individual river sections did not meet the standards for a few months of the year, the water quality of the remaining sections could be improved from class V, the current state, to class IV, and ammonia nitrogen and chemical oxygen demand (COD) standards could be achieved 82% and 96% of the time, respectively. These results show that the proposed model is effective and fit for purpose.

A satisfação das necessidades hídricas humanas e ambientais é um tema que tem merecido atenção no âmbito da gestão e planejamento dos recursos hídricos no mundo. As incertezas sobre as possiblidades de atender as necessidades de água futuras na bacia do rio Inhanombe motivaram a realização deste trabalho. Este artigo tem como objetivo avaliar a capacidade de satisfação das necessidades de água, através da aplicação do WEAP (Water Evaluation And Planning System). Simularam-se três cenários: o cenário de referência que corresponde a exploração atual dos recursos hídricos; dois cenários de impacto: Médio e Alto crescimento que correspondem à expansão da área irrigada e do crescimento populacional entre 2019 e 2040. Os resultados obtidos demonstram a incapacidade do sistema de satisfazer as necessidades futuras nos cenários de Médio e Alto crescimento com níveis baixos de garantias mensais e muitas falhas no fornecimento. Water Allocation Assessment in the Inhanombe river basin, Mozambique A B S T R A C TMeeting human and environmental water needs is a topic that has deserved attention in the area of water resources management and planning in the world. Uncertainties about the possibilities of meeting future water needs in the Inhanombe river basin motivated this work. This article aims to evaluate the ability to meet water needs through the application of WEAP.
