Water Uses

Conflicts around the multi-purpose water uses of Lake Diefenbaker (LD) in Saskatchewan, Canada need to be addressed to meet rapidly expanding water demands in the arid Canadian prairie region. This study explores these conflicts to advance collaborative planning as a means for improving the current water governance and management of this lake. Qualitative methodology that employed a wide participatory approach was used to collect focus group data from 92 individuals, who formed a community of water users. Results indicate that the community of water users is unified in wanting to maintain water quality and quantity, preserving the lake’s aesthetics, and reducing water source vulnerability. Results also show these users are faced with water resource conflicts resulting from lack of coherence of regulatory instruments in the current governance regime, and acceptable management procedures of both consumptive and contemporary water uses that are interlinked in seven areas of: irrigation, industrial, and recreational water uses; reservoir water level for flood control and hydroelectricity production; wastewater and lagoon management; fish farm operations; and regional water development projects. As a means of advancing collaborative planning, improvements in water allocation and regulatory instruments could be made to dissipate consumptive use conflicts and fill the under-regulation void that exists for contemporary water uses. Additionally, a comprehensive LD water use master plan, as a shared vision to improve participation in governance, could be developed to direct the water uses that have emerged over time. This study suggests that these three areas are practical starting conditions that would enable successful collaborative planning for the seven areas of water uses. Focusing on these three areas would ensure the current and future needs of the community of water users are met, while avoiding reactive ways of solving water problems in the LD region, especially as the water crisis in the Canadian Prairie region where LD is located is expected to intensify.

AbstractIn recent years, it has become popular for some of countries and regions to adapt the system of governance to varied and complex issues concerned with regional development and the environment. Watershed management is possibly the best example of this. It involves flood control, water use management and river environment simultaneously. Therefore, comprehensive watershed-based management should be aimed at balancing those aims. The objectives of this study are to introduce the notion of environmental governance into the planning process, to establish a method for assessing the alternatives and to develop a procedure for determining the most appropriate plan for environmental governance. The planning process here is based on strategic environment assessment (SEA). To verify the hypothetical approach, the middle river basin in the Tokachi River, Japan was selected as a case study. In practice, after workshop discussions, it was found to have the appropriate degree of consensus based on the balance of flood control and environmental protection in the watershed.

Reef Fish Species

Specifying annual catch limits for artisanal fisheries, low economic value stocks, or bycatch species is problematic due to data limitations. Many empirical management procedures (MPs) have been developed that provide catch advice based on achieving a stable catch or a historical target (i.e., instead of maximum sustainable yield). However, a thorough comparison of derived yield streams between empirical MPs and stock assessment models has not been explored. We first evaluate trade-offs in conservation and yield metrics for data-limited approaches through management strategy evaluation (MSE) of seven data-rich reef fish species in the Gulf of Mexico. We then apply data-limited approaches for each species and compare how catch advice differs from current age-based assessment models. MSEs identified empirical MPs (e.g., using relative abundance) as a compromise between data requirements and the ability to consistently achieve management objectives (e.g., prevent overfishing). Catch advice differed greatly among data-limited approaches and current assessments, likely due to data inputs and assumptions. Adaptive MPs become clearly viable options that can achieve management objectives while incorporating auxiliary data beyond catch-only approaches.

The Future

The future management of water resources must take into account the levels of beneficial use that apply to various water use sectors. Competition for water during periods of low natural availability (droughts) suggests that users may not have access to their full supply requirement all of the time. This is particularly true of regions such as South Africa where natural water availability is highly variable and possibly will be even more so in the future. Socioeconomic evaluations of water allocation strategies should therefore account for the impacts of periodic restrictions (or shortfalls) in supply across different water use sectors. This paper presents an approach to designing water allocation operating rules that can account for restrictions and their impacts on individual water users, as well as on the community as a whole. The approach is illustrated using hypothetical data, as real data are not generally available. The paper maintains that it is important for socioeconomic evaluation methods to account for the possible effects of supply restrictions as well as the relative benefits of the normal supply volume. If they do not, they will not provide the information required by water resource engineers to design and operate water allocation systems.

Abstract. Irrigation is the most important water use sector accounting for about 70% of the global freshwater withdrawals and 90% of consumptive water uses. While the extent of irrigation and related water uses are reported in statistical databases or estimated by model simulations, information on the source of irrigation water is scarce and very scattered. Here we present a new global inventory on the extent of areas irrigated with groundwater, surface water or non-conventional sources, and we determine the related consumptive water uses. The inventory provides data for 15 038 national and sub-national administrative units. Irrigated area was provided by census-based statistics from international and national organizations. A global model was then applied to simulate consumptive water uses for irrigation by water source. Globally, area equipped for irrigation is currently about 301 million ha of which 38% are equipped for irrigation with groundwater. Total consumptive groundwater use for irrigation is estimated as 545 km3 yr−1, or 43% of the total consumptive irrigation water use of 1 277 km3 yr−1. The countries with the largest extent of areas equipped for irrigation with groundwater, in absolute terms, are India (39 million ha), China (19 million ha) and the United States of America (17 million ha). Groundwater use in irrigation is increasing both in absolute terms and in percentage of total irrigation, leading in places to concentrations of users exploiting groundwater storage at rates above groundwater recharge. Despite the uncertainties associated with statistical data available to track patterns and growth of groundwater use for irrigation, the inventory presented here is a major step towards a more informed assessment of agricultural water use and its consequences for the global water cycle.

Demographic Surveys

Studies have shown that householders' perceptions of their water use are often not well matched with their actual water use. There has been less research, however, investigating whether this bias is related to specific types of end use and/or specific types of socio-demographic and socio-demographic household profiles. A high resolution smart metering study producing a detailed end use event registry as well as psycho-social and socio-demographic surveys, stock inventory audits and self-reported water diaries was completed for 250 households located in South-east Queensland, Australia. The study examined the contributions of end uses to total water use for each group identified as ‘low’, ‘medium’ or ‘high’ water users. Analyses were conducted to examine the socio-demographic variables such as income, percentage of water efficient stock, family size and composition, that characterise each self-identified water usage group. The paper concludes with a discussion of the general characteristics of groups that overestimate and underestimate their water use and how this knowledge can be used to inform demand management policy such as targeted community education programmes.

<em>Abstract</em>.—We examined perceptions of and responses to crowding by boat anglers on hydropower and flood-control reservoirs in western North Carolina by reviewing angler opinion information obtained during year-long creel surveys conducted 1997–2006. Interview topics included subjective ratings of crowding on the day of interview, boating safety concerns, alterations to fishing trips due to crowding, types of behavioral alterations used to avoid crowding, and incidence of night fishing. Angler perceptions of crowding and resulting changes in fishing behavior were typically higher in warmer months and on reservoirs with greater fishing pressure. However, boat anglers on reservoirs with high fishing pressure but low nonfishing boat traffic reported fewer crowding concerns than on reservoirs with more diverse boating use. Spatial responses to crowding were reported on all waters and included fishing coves, diverting fishing trips to less-crowded reservoirs, and leaving the reservoir to avoid crowds. Temporal responses to crowding were more common on heavily used reservoirs and included fishing at night, avoiding weekends, and avoiding summer months. We recommend focusing access improvements on enhancements for off-season and night fishing, including improved access-area lighting and low-water ramps and docks.

Mechanized raised-bed technology (MRBT) is recognized as an important measure to achieve higher crop productivity and water-use efficiency in intensive irrigated systems. Development efforts on spreading this technology require adequate understanding of the qualities and drivers of farmers’ adoption of MRBT. Research in agricultural innovation adoption has identified the importance of the socio-ecological context (SEC) that influences the livelihood of farmers adopting new technologies. This study introduces an agricultural livelihood systems (ALS) typology-based approach for guiding concrete analytical steps and statistical methods in evaluating the effects of system SEC diversity in two Egyptian governorates. We objectively classify a population of sampled farming households into a limited number of ALS types and use inferential statistics for the whole sampled population and individual ALS types to discover adoption drivers. Values added by the ALS approach confirm the widespread role of common determinants of MRBT adoption across ALS types, household groups subject to the effects MRBT, and show new causal effects. The presented advanced approach and empirical findings will be useful for enhancing targeting and out-scaling of MRBT practices toward achieving sustainable agricultural water uses at scale.

Rapidly declining groundwater levels since the early 1990s have raised serious concern in Monroe County, Michigan. Hydrological studies suggest that land-use changes have caused this decline. The mechanisms linking land-use and groundwater dynamics are not clear, however. In this paper I present WULUM, the Water-Use and Land-Use Model, an agent-based model that serves as an analytical framework to understand how these processes interact to create the observed patterns of resource depletion, and to suggest policies to reverse the process. The land-use component includes the main groundwater extractors in the county—stone quarries, golf courses, farms, and households. The groundwater component includes the glacial deposits and the underlying bedrock acquifer. The behavior of water users is defined by simple rules that determine their location and consumption. The dynamics of groundwater are represented through infiltration and diffusion rules between each cell and its immediate neighbors. Initial explorations with the model showed that land-use patterns contributed significantly to groundwater declines, while eliminating quarry dewatering did not entirely solve the problem. Both low-density and high-density zoning restrictions improved aquifer conditions over medium-density development, suggesting a nonlinear relationship between intensity of residential use and groundwater levels. Moreover, of all the natural and policy variables, zoning had the greatest influence on urban settlement and therefore on resource consumption.

Different Levels

In this article, a general methodology for simulation of water resources management is suggested. The research has been conducted in three different levels: a deep analysis of the historical management procedures, the development of some alternative ways to optimal management, and the establishment of planning criteria at short, middle, and long term. The main constraints, divided into three categories according to the severity of probable losses, have been defined as a function of several expected goals: hydro power, flood control, recreational activities, etc. The model was applied with excellent results to the upper region of the St. François river basin (Québec, Canada). Key words: simulation, resources management, mathematical models, optimization.
