As most cities share their water basins with rural areas, an efficient and environmentally sensible urban water management system needs to consider the interplay between urban and rural water uses. This article analyses the three main challenges at this interface: increased competition for water resources (scarcity); flood management (abundance); and freshwater quality conservation (pollution). The merit of potential policy options is discussed from an economics perspective, taking examples from successful experiences in cities around the world. The benefits and challenges arising from enhanced coordination and integration between urban and rural water management are highlighted.

Denmark is making continuous efforts to attain sustainable groundwater management. With groundwater constituting virtually the only resource for all water uses, groundwater management was addressed early on and has progressed over the last century. This article gives an overview of the advances, along with past and present challenges in securing sustainable groundwater utilization. The objective is to document comprehensively the Danish case and to highlight some of the unique conditions and principles that have shaped and facilitated groundwater management in the country.
Desalination and the commons: tragedy or triumph?

A policy is more likely to be economically efficient when its costs and benefits fall on the same group, but politicians can allocate costs and benefits to different groups within their jurisdictional commons. This article examines the distribution of costs and benefits from desalination projects using examples from San Diego, Almería and Riyadh. The examples illustrate how mismatches between costs and benefits can persist or change as politicians adjust the policy portfolio to balance inefficiency and political risk.

Current subsidies to residential water users in Oman are estimated at USD 314 million/y. This study estimates the demand function for residential water in Muscat, Oman, for households living in villas. A two-stage least squares econometric model with lagged average water price was used with socio-economic variables. Price elasticity for residential water in Muscat was estimated as –2.10. This high price elasticity is explained by the large proportion of water used for outdoor purposes. This study indicates that it may be possible to manage water demand in Muscat through modifying the price of water and reforming subsidies for residential water.

Difficulties in monitoring groundwater extraction cause groundwater regulations to fail worldwide. In two counties in north-west China local water authorities have installed smart card machines to monitor and regulate farmers’ groundwater use. Data from a household survey and in-depth interviews are used to evaluate the effectiveness of the different regulatory institutions implemented with help of the smart card machines. In the given context, groundwater quota is more effective in curbing farmers’ groundwater use than the tiered groundwater pricing. The study shows that the usefulness of smart card machines depends on their embedding in the societal context and related regulatory institutions.

From the analysis of stakeholders’ attitudes, this article explores problems, opportunities and constraints for improving sustainability and establishing better water governance processes in the selected case study, the Neste irrigation canal (France). Data were collected through semi-structured interviews and analyzed by means of a new codification system for identifying the affinities and confrontations between stakeholder demands. Results revealed that there are conceptual and practical heterogeneities among the preferences of stakeholder groups regarding irrigation management, sustainable attitudes and governance promotion. These results can be used by stakeholders and the relevant authorities as a first step in customizing their interventions.

This article presents a modified water poverty index that captures several waterscape attributes to better understand complex issues surrounding water. Household surveys (n = 300), water quality tests (n = 375) and qualitative methods were deployed to examine 14 posttsunami settlements in Nagapattinam and Karaikal Districts (India) through the lens of water. Data were used to develop a contextualized, participant-driven water poverty index to measure water poverty at several scales. Statistical tests revealed significant differences between the two districts (p ≤ .0001) and between rural and urban areas within each district (p ≤ .0001). Three weight schemes (one dictated entirely by research participants) produced analogous outcomes though predicated on different indicator arrangements.

A 294-year streamflow record of the upper Kurshab River was inferred from tree-ring width chronology of Turkestan juniper from the PamirAlai Mountains of Kyrgyzstan. The reconstructed streamflow variations were consistent with other hydrometeorological reconstructions of northern Pakistan and western Tien Shan on a decadal timescale, which demonstrate both increased and decreased streamflow intervals and trends. The new reconstruction and other hydrometeorological series successfully captured the recent wetting trend of Central Asia. Wavelet analysis indicates that decadal and interannual cycles exist in the reconstructed streamflow, which may be linked to solar activity and the North Atlantic Oscillation.

This paper presents a new decision-making strategy for hydropower operations to handle uncertainty of forecasting precipitation. This strategy takes into account three basic components: uncertainty of precipitation, operation policies and a risk-evaluation model. In realtime operation, precipitations with different probabilities at different forecasting levels are obtained, and these precipitations are applied to forecast inflows using a hydrological forecasting model. Based on the forecasting inflows, the operation policies and risks with different probabilities are obtained. This study implements China’s Huanren reservoir and medium-term precipitation forecasts from the Global Forecast System to study the efficiency and stability of this strategy.

The Midwestern United States is the heartland of agriculture production, and changes in the hydro-climatology may affect both the quantity and the quality of production. Seasonal temperature and precipitation were analyzed for trends and shifts. The results indicate an increasing trend in spring temperature (6.4 °F) and summer precipitation (1.2 inches). Shifts in the variables were dominant during two periods: 1920–1930 and 1970–1990. The observed changes not only provide scientific reference for assessing the impact on water resources as a result of climate change, but also help water managers and planners in taking proactive decisions to mitigate the water stress in the region.

Little is done to connect hydrological modelling with stakeholder participation. This study incorporates agricultural development and climatic changes within the Water Evaluation and Planning hydrological model. This is done with a participatory approach involving four scenario workshops, 400 household surveys and two focus group discussions in the period of 2010–2012 for the ungauged Huai Sai Bat sub-basin as a case study in the Mekong region. The modelling results indicate future increased streamflow during the wet (monsoon) season in response to shifts in the regional climate. Modelled land-use and management changes brought about large unmet water demands, primarily in the dry season.
