In order to balance between financial and social constraints of water and respond to competing for water requirements, it is important to sustain and manage essential water systems. Therefore, this paper aims to evaluate sustainable water management in specific sectors: urban, agricultural, and environmental and addresses questions, such as (1) how is sustainable water management described and assessed? (2) what challenges occur in sustainable water development in different sectors? (3) which aspects/elements of sustainable water developments are important in agricultural and urban water management? and (4) how do different countries improve sustainable water management? Depending on the complexity of water systems, water users and sources of water, techniques for estimating performances of water management can be simple (such as indicator techniques) or complex (such as several models). The techniques are analyzed in this study. The findings from implementing sustainable water management suggest that all water users consider which source of water (e.g., usable and reusable) is more suitable to use. They also state that increasing agricultural water use efficiency can significantly reduce total water consumption, which can lead to global food security. In addition, results showed that the level of local infrastructure conditions and financial capabilities are more important in sustainable water management than is the level of regional development.

Abstract Past water resource developments in dryland regions rarely estimated the full suite of environmental and social impacts arising from damming and diverting water for food production. Nowadays there is a greater focus on sustainable resource development which considers the economic, social and environmental costs and benefits. A challenge is to apply tools and methods which can capture the often disparate knowledge and data describing many costs and benefits. This paper describes a proof ...

Abstract This study presents a hybrid Finite Volume – Finite Element (FV-FE) model that describes the coupled surface-subsurface flow processes occurring during furrow irrigation and fertigation. The numerical approach combines a one-dimensional description of water flow and solute transport in an open channel with a two-dimensional description of water flow and solute transport in a subsurface soil domain, thus reducing the dimensionality of the problem and the computational cost. The modeling ...

Abstract This article shed light on the shadow state, investigating who belongs to it, their interests, and their relation to the water sector. This is important because Jordan is known to be among the most water scarce countries in the world and some water professionals see in the shadow state an obstacle to implementing successful water policies, resulting to be one of the main reasons behind inefficiencies in the water sector in the country. Furthermore, an in-depth investigation of the relat...

Because natural ecosystems and ecosystem services (ES) are both critical to the well-being of humankind, it is important to understand their relationships and congruence for conservation planning. Spatial conservation planning is required to set focused preservation priorities and to assess future ecological implications. This study uses the combined measures of ES models and ES potential to estimate and analyze all four groups of ecosystem services to generate opportunities to maximize ecosyste...
Over the past few decades, the concept of resilience has emerged as an important consideration in the planning and management of water infrastructure systems. Accordingly, various resilience measures have been developed for the quantitative evaluation and decision-making of systems. There are, however, numerous considerations and no clear choice of which measure, if any, provides the most appropriate representation of resilience for a given application. This study provides a critical review of q...
For UK Water and Sewerage Companies (WaSCs), the capacity to innovate capital investment processes, and consequently performance outcomes is fundamental as they seek to deliberately change infrastructure to improve the sustainability of service delivery within a comparatively regulated framework. Innovation is viewed here as being either incremental or radical changes to the products (services) and processes (ways of delivering services) which are typical to the organisation (WaSCs). Product and...
AbstractIndia, an ancient rural and agricultural society that is rapidly modernizing, receives a fair share of its yearly precipitation in only a few days of the monsoon, with high inter-annual variability. In most of its regions, therefore, India needs to store a large proportion of its annual runoff in reservoirs for use in non-monsoon months. In spite of this strategy being in operation for the last 60 years, India’s per capita reservoir storage is relatively small, and water-use efficiency a...
There were major changes to the water management framework for New Zealand that occurred in the late 1980s which brought in new legislation, the Resource Management Act (RMA ) ; new water administration bodies based on catchments, the regional councils; an Environment Court; and, a change in the primary role for government from service provider to water regulator.
The systems, processes and infrastructure through which water is managed— particularly in drainage, waste water and drinking water schemes— are often incomprehensible and invisible to the general public, leading to gaps in knowledge about how water operates in our daily lives. This fosters ignorance, powerlessness and irresponsible practices, which are significant factors in escalating water-related environmental issues such as flooding, drought and pollution. The project, Living, Working, Playi...

In order to develop a valued decision-support system for climate alteration policy and planning, recognizing the regionally-specific features of the climate change, energy-water nexus, and the history of the current and possible future climate, water and energy supply systems is necessary. This paper presents an integrated climate change, water/energy modeling platform which allows tailored climate alteration and water-energy assessments. This modeling platform is established and described in de...

In response to the climate change, hydrologic and environmental changes and increased uncertainties, implication of water resilience in a context of water governance is essential for improved management. This study aims to answer the following questions: 1) what are different types of resilience with regard to its several definitions, 2) what is the relationship between resilience, trend and performance in water governance. This research applied literature reviews (as theoretical approach) and i...
In order to timely understand the status of sustainable utilization of urban water resources and to effectively plan and manage the use of water resources, in this study, an extension evaluation method is used to evaluate the sustainable utilization of water resources. Firstly, a sustainable utilization index system of water resources is constructed from the perspectives of water resources conditions, development and utilization, social economy, ecological environment, and water resources manage...
