Study on the Economic Valuation of Water Resources and the Allocation of Rights and Interests in Water Resources

With the increasing scarcity and uneven distribution of water resources around the world, scientific assessment and rational allocation of water resources have become urgent tasks in today’s society. This study focuses on the assessment of the economic value of water resources and the allocation of water resources’ rights and interests, aiming to explore how to accurately assess the economic value of water resources and how to realize a reasonable and fair allocation of resources’ rights and interests among different stakeholders. The importance of water resources and their values in economic, ecological and social aspects are analyzed from the background of global water resources issues. Reveal the multidimensional value of water resources by integrating market and non-market valuation methods. The study further examines the existing equity allocation mechanisms, analyzes their strengths and weaknesses, and points out that the traditional mechanisms may lead to over-exploitation of resources and imbalance of equity. The systematic theoretical discussions and practical case studies provide new perspectives and methods for water resources management and policy making

Ecological and economic assessment of the use of water resources of Ukraine in the context of sustainable development

Water resources are crucial for sustaining human life, industry, agriculture, and ecosystems. However, increasing pressure on these resources, pollution of water sources and climate change pose serious challenges to their effective management. It was determined that the water resources of Ukraine have great potential for the development of society, but they require effective management taking into account the principles of sustainable development. It is substantiated that the formation of the fundamental scientific basis for the evaluation of water resources of Ukraine should be based on the use of ecological and economic approaches, in particular, on the study of the water balance, assessment of ecosystem services, cost analysis and other tools for determining the ecological and economic value of water resources. A comparison of the indicators of the achievement of the Sustainable Development Goals (SDGs) 6 "Ensuring the availability and rational use of water resources and sanitation for all" between Ukraine and Poland was carried out. The study revealed certain differences and similarities in the level of achievement of both countries in this direction. Based on the results of the study, it was established that ecological and economic approaches to the assessment of water resources are effective tools for determining their value and making rational decisions about their management, which allows taking into account not only economic aspects, but also the impact on ecosystems and human health.

Characterizing Drought Behavior in the Colorado River Basin Using Unsupervised Machine Learning

AbstractDrought is a pressing issue for the Colorado River Basin (CRB) due to the social and economic value of water resources in the region and the significant uncertainty of future drought under climate change. Here, we use climate simulations from various Earth System Models (ESMs) to force the Variable Infiltration Capacity hydrologic model and project multiple drought indicators for the sub‐watersheds within the CRB. We apply an unsupervised machine learning (ML) based on Non‐Negative Matrix Factorization using K‐means clustering (NMFk) to synthesize the simulated historical, future, and change in drought indicators. The unsupervised ML approach can identify sub‐watersheds where key changes to drought indicator behavior occur, including shifts in snowpack, snowmelt timing, precipitation, and evapotranspiration. While changes in future precipitation vary across ESMs, the results indicate that the Upper CRB will experience increasing evaporative demand and surface‐water scarcity, with some locations experiencing a shift from a radiation‐limited to a water‐limited evaporation regime in the summer. Large shifts in peak runoff are observed in snowmelt‐dominant sub‐watersheds, with complete disappearance of the snowmelt signal for some sub‐watersheds. The work demonstrates the utility of the NMFk algorithm to efficiently identify behavioral changes of drought indicators across space and time and to quickly analyze and interpret hydro climate model results.

Vulnerability of Water Resources to Climate Change: Adaptation and Resilience Strategies for Sustainable Development in Nigeria

Nigeria faces inexorable climate change in recent times. This phenomenon will have a profound effect on the long-term sustainable socio-economic development and is also likely to jeopardize achievement of economic development of the country. All economic and social sectors will be adversely affected. The water resources sector is one that will be strongly impacted by climate change. Against a background of increasing demand for potable water, sea-level rise may lead to flooding of lowlands and seawater intrusion into coastal aquifers, while variability in climate may see more intense rainstorms resulting both in increased run-off leading to increased flooding and reduced recharge leading to aquifer depletion. Such impacts are already having negative ripple effects on other vital aspects of the economy such as the tourism, recreational, agricultural and industrial sectors. Unfortunately, adequate management of water resources in Nigeria is sorely lacking. Extensive studies to quantify the likely impacts of future climate change and climate variability on water resources in Nigeria are not available. In many cases, baseline data which may be used to track changes are sparse or non-existent. The impacts of climate change and economic value of water resources will form the basis for the development of adaptation strategies with regards to the sustainable management of regional and national water resources. This paper therefore explores the probable effect climate change will have on water resources in Nigeria, the fall-out from these effects and strategies for mitigating potential negative impacts for sustainable development.

The value of surface water resources in the socio-economic development of Ho Chi Minh City

Surface water sources in Ho Chi Minh City (HCMC) are being exploited for various purposes such as water supply for daily life, industry and services ; irrigation, animal husbandry, aquaculture ; navigation, environmental landscaping, waste reception and assimilation, etc. Each of these uses has its own benefits and values. However, up to now, the economic value of these water resources has not been fully appreciated and evaluated objectively. This paper presents an overview of the economic value of water resources and the economic valuation of some of the typical value types used in HCMC by 2016, including use for living, industrial, service, irrigation, transportation and environmental landscape.

Optimization of virtual water flow via grain trade within China

The irrational virtual water flow caused by grain trade makes water use efficiency low and further threatens grain security in China. However, optimizing the grain virtual water trade flow from the perspective of the economic value of water resources has rarely been carried out in current research. This paper proposes a linear optimization model considering opportunity cost to fill this gap. The current situation of grain virtual water trade is analyzed and we find an irrational trade mode which quantity and direction of grain virtual water trade in some provinces are not consistent with actual demand. Then, opportunity cost is added to the linear optimization model to adjust grain virtual water trade which shows several advantages compared to general linear optimization model. Results show that huge virtual flow is generated, up to 1179.24 billion cubic meters of water. And the economic value generated by grain virtual water trade can not only cover the transportation cost but can also eventually generate economic benefits of 7410 billion yuan. Finally, the relevant conclusions and implications of adjusting China’s grain virtual water trade are obtained.

Analysing hydropower production in stressed river basins within the SEEA-W approach: the Jucar River case

Abstract Hydropower generation represents an important contribution to meeting the challenges of today's increasing world energy needs. It uses about 44% of water in Europe, and it is the main user of water in most OECD countries. However, in most cases, the energy sector is not a water consumer. The largest part of these withdrawals is immediately returned into the environment, being able to be used by other sectors, which is its most prominent characteristic. In order to understand the water-energy nexus and the challenges that the environment and other water users face, the European Commission proposed the use of water accounts in order to measure the influence of each water user, infrastructure and management decision to the total economic value of water resources in a given basin. In this sense, the SEEA-W is the most well-known approach of hybrid accounting as it provides a standard approach to compare results between different regions. This research analyses hydropower production in the Jucar River Basin (Spain), which is currently water-stressed by consumptive demands, within the SEEA-W approach. The results demonstrate that the SEEA-W approach needs some improvement in order to represent hydropower production properly.

Optimal Allocation of Water Resources Model for Different Growth Stages of Crops under Uncertainty

In this study, an integrated interval nonlinear programming model based on Jensen’s water production function is proposed for the optimal allocation of water resources under uncertainty in agricultural irrigation. The model provides an effective approach to solve the problems for crop irrigation schedules and to successfully deal with the inconsistencies in crop water requirements and rain capacity. The model can allocate the limited water to different growth stages of crops based on Jensen’s crop water production function, which further improves water use efficiency. The method provides the means to promote the development of water-saving irrigation and further improves the economic value of water resources. Two major advantages make the model unique in comparison to the other optimization techniques. First, it can solve the uncertainties of the agricultural water resources system, and the results are given in the form of intervals, which can provide more leeway for decision makers. Second, the rainfall was divided into 18 stages with 10 days per stage in this paper (each of the crop growth stages were matched with different stages); then, the limited water resources were optimally allocated to different crops in different growth stages based on Jensen’s model. The model not only increases the output per unit of water but also improves water use efficiency. In this paper, the Yongchang irrigation district in Wuwei was taken as an example to demonstrate the feasibility of the proposed model. The results are helpful for water resources managers in making decisions about water allocation and striking a balance between environmental and economic objectives.

Total Economic Value (TEV) provides a framework to estimate the economic value of water resources including groundwater with multiple applications to natural resource economics and environmental economics. Crucial to the application of economic analysis to natural resources are techniques to value the resources as an economic value that is expressed in monetary terms. On the other hand, the aim of TEV estimation is to determine the economic value of water resources including 'use' with production and recreation and 'non-use' such as existence values. TEV is used to assess the economic value of water resources for the multiple goods, and environmental 'services' that are provided by a water resource and also used to assess options for water use, for example balancing production values provided by water resource use against the cost of resource degradation by that use. The value of TEV can be assessed over time where pollution or unsustainable use may reduce the economic value of an environmental asset. Therefore, values are used to assess options of resource use, sometimes leading to policies on resource conservation or allocation. In conclusion, the application of TEV would be well adjusted over Jeju Island where groundwater resources account for more than 98% water resources and the budget of water demand/supply shows disparity over the Island.

Economic Value of Water Resources of the Upper Reaches of the Xin'an River Basin, China

Estimating the value of water resources not only forms the basis of water rights transactions between upstream and downstream and eco-compensation standards, but also provides scientific data for the reasonable establishment of local water prices and promotes sustainable use and efficient management. Here, we estimate the economic value of the water resources of the upper reaches of the Xin'an River basin. Our purpose is to establish theoretical support for eco—compensation standardization and provide data for the protection of water resources and water price reform.
