It is well recognized that climatic variability and human activities are resulting in severe water scarcity in China, especially in the mega city Beijing; one important issue is how to manage water resources in order to tackle this situation. This paper assesses the implementation of the Strictest Administration of Water Resources in Beijing, which was issued by the State Council of China in 2012. The assessment is threefold: (a) analysis of water consumption conditions in Beijing, (b) analysis of water resources management systems in Beijing, and (c) existing problems in the current water management system. Our study suggests that Beijing needs to focus more on improving the building of water resources management agencies, taking effective economic measures, strengthening law construction, developing advanced techniques for water-saving, and strengthening the building of a water-saving culture.

Abstract Because of the shortage of water resources, the phenomenon of groundwater over-extraction is widespread in many parts of the world, which has become a hot issue to be solved. The traditional idea of water resources management only considering blue water (stream flow) can't meet the demand of sustainable utilization of water resources. Blue water accounts for less than 40% of total rainfall, while green water (evapotranspiration) accounts for more than 60% of total rainfall. In the natural environment, vegetation growth mainly depends on green water, which is often neglected. Obviously, the traditional water resources management without considering green water has obvious deficiencies, which can't really reflect the regional water consumption situation in the water resources management. And only by limiting water consumption can achieve the real water saving. In addition, the mode of water resources development and utilization has changed from "supply according to demand" to "demand according to supply". In this background, for many regions with limited water resources, it is impossible to rely on excessive water intake for development, and sustainable development of regional can only be realized by truly controlling water demand. This paper chooses Shijin Irrigation District in the North China Plain as the research area, where agricultural water consumption is high and groundwater over-extraction is serious, and ecological environment is bad. In order to alleviate this situation, comprehensive regulation of water resources based ET is necessary. Therefore, this paper focuses on the concept of ET water resources management and includes green water into water resources assessment. Based on the principle of water balance, the target ET value of crops in the study area is calculated, and the ET value is taken as the target of water resources regulation. The actual water consumption is calculated by Penman-Monteith formula, and reduction of crop water consumption is obtained according to the difference between actual ET and target ET. The reduction in crop water consumption leads to a reduction in demand for water supply, which reduces groundwater extraction. The results of this study can provide necessary technical support for solving the problem of groundwater over-extraction and realizing real water saving.

Establishing a modern water rights system (WRS) that is suited to the Strictest Water Resources Management System (SWRM) is an important reform in China's water resources management in terms of addressing current water issues. However, there are still several problems in the construction of a WRS, such as ambiguity in the definition of water rights, weakness in the infrastructure of water rights and imperfect WRS legislation. Moreover, water rights allocation (WRA) and water rights trading (WRT), which are two core components of water rights, still have some problems that remain to be solved. The ‘Three Red Lines’, which make up the core of the SWRM, are expounded upon, and the relationship between the WRS and the SWRM is analyzed. Finally, some appropriate recommendations based on the ‘Three Red Lines’ are provided to perfect the WRS so that it is suitable for the SWRM. In this paper, we conclude that the WRS is a type of water resource management that can effectively solve the current water issues in China. Significant efforts have been made in the construction of the WRS, which has achieved remarkable success in a period of exploration and practice in China. The construction of the WRS supports sustainable social and economic development and results in harmonious relationships between humans and nature.

Peat swamp forest is a unique and fragile ecosystem, with specific flora and fauna that play important roles in maintaining healthy natural conditions with high economic values. This habitat also has important role for equilibrium and maintenance of living environment such as water reservoir, carbon storage, climate change, and biodiversity. Utilization of peatland for agriculture, plantations, and other activities often lead not only to controversy, but also cause land and ecosystem degradation, including water resources availability. The objective of this research was to study comprehensive ecohydrology aspects in ex-mega rice project in Central Kalimantan in order to support sustainable agricultural practices and water resources management in peatland areas. The results of the study showed that the sustainability of agricultural systems in peatland was strongly influenced by ecological aspect. This aspect can be carried out from the condition of water management system, water color condition, and possible incidence of fires. The level of suitability for crops plantation was low (S3), with the limiting factors of pH, nutrient availability, and the risk of inundation. In this case, water gates should be installed to improve water management system. Water quality in this area was typical of peat water and do not meet the requirement for daily use for the local people.

In this study, Calabar annual total rainfall was analysed for trend and climatic variability events with focus on drought occurrence. Monthly rainfall data from in situ measurements over a 41 year period (1972-2012) were used for the study. Standard tests were used to evaluate the trends and variability in annual rainfall. Rainfall variability was estimated as standardized rainfall departures and used to identify and delimitate the dry and wet spell sequences of Calabar rainfall. The rainfall series were analysed for Standardized Precipitation Index (SPI) using SPSS Version 17 software. The least squares regression plot was executed using Excel 2010 to depict the trend, variability and regression parameters. The average annual rainfall for Calabar is 2984.64 mm with standard deviation of 394.9 mm. 36.59% of the period showed positive SPI while 63.41 % of the period indicated negative SPI values. Wet spell dominated the later part of the period but sandwiched with dry spells whereas dry spell were dominant from 1972 to 1994. The area experienced a non-significant upward trend of 15.21 mm per year over the interval. The SPI values indicate that Calabar experienced distinct inter-annual rainfall cycles that represent mild to extreme droughts and wet spells which are a demonstration of consequential annual rainfall variability. The results underscore the need for effective monitoring of Calabar rainfall for prompt warnings and responses that would guarantee effective risk reduction and management in the run-in to the occurrence of the extreme events. The paper further highlights the need for data-driven approach to policy making in water resources management. This would provide a fascinating insight into the improvement in long-term water resources management in the city and its suburbs.

Abstract Integrated water resources management (IWRM) has been criticized yet it is the dominant approach to water resources management in developing countries. The criticism emanates from the manifold unfounded assumptions made during implementation on issues such as availability of technology and infrastructure, privatization and sustainable financing, human resource capacity, government interference, etc. The Pra Basin has been implementing IWRM since 2011. The basin houses nine out of the 17 artificial reservoirs constructed in Ghana for drinking water supply. It is therefore prudent that the basin's water resources are given extra management care to ensure sustainable water quality and quantity for growth and development. However, much uncertainty still exists about whether the best water management system is being practiced, whether the system is working well, or needs improvement. This study examines the effectiveness of water resources management in the Pra Basin of Ghana. This study used interviews, field observations, and documents such as Pra Basin IWRM plan, the national IWRM plan, etc., to assess the effectiveness of IWRM in the Pra Basin. The result of the study showed that IWRM although appropriate for the basin had implementation gaps. These gaps are potential contributors to deteriorating water quality.

Constrained Programming

In order to formulate water allocation schemes under uncertainties in the water resources management systems, an inexact multistage stochastic chance constrained programming (IMSCCP) model is proposed. The model integrates stochastic chance constrained programming, multistage stochastic programming, and inexact stochastic programming within a general optimization framework to handle the uncertainties occurring in both constraints and objective. These uncertainties are expressed as probability distributions, interval with multiply distributed stochastic boundaries, dynamic features of the long-term water allocation plans, and so on. Compared with the existing inexact multistage stochastic programming, the IMSCCP can be used to assess more system risks and handle more complicated uncertainties in water resources management systems. The IMSCCP model is applied to a hypothetical case study of water resources management. In order to construct an approximate solution for the model, a hybrid algorithm, which incorporates stochastic simulation, back propagation neural network, and genetic algorithm, is proposed. The results show that the optimal value represents the maximal net system benefit achieved with a given confidence level under chance constraints, and the solutions provide optimal water allocation schemes to multiple users over a multiperiod planning horizon.
