A global limit on water consumption is necessary, but the suggested planetary boundary of 4,000 cubic kilometres per year is too generous.

During the time of the Soviet Union, the Central Asian states managed their water resources on the meso level according to administrative rather than hydrological boundaries. It was only in 2003 that Uzbekistan shifted from administrative to hydrological boundaries for water management. Using the example of Khorezm Province in the lower Amu Darya basin, this paper shows that redefining boundaries is a political process, which led in Khorezm to new boundaries which are partly determined by hydraulic, not hydrological, and political considerations. Nevertheless, the new management approach has created more equity amongst the different districts in terms of water supply per irrigated area. However, simple equity in water supply did not take into consideration other issues, such as infrastructure, hydrogeological zones and crop production. In addition, the official data show that the achieved equity was based on an overall increase in water supply to the individual districts and to Khorezm as a whole. When only the increase in water supply to the individual districts is taken into consideration, it appears that the location of the main office and the regional provenance of the main staff influenced water supply to specific districts. Finally, based on the data presented for Khorezm Province the paper goes a stage further and questions the real value of the new water management boundaries implemented in Khorezm.

Subsurface movement of water within the alluvial formations of Ganga Basin System of North and East India, extending over an area of 1 million km2 , was simulated using Visual MODFLOW based transient numerical model. The study incorporates historical groundwater developments as recorded by various concerned agencies and also accommodates the role of some of the major tributaries of River Ganga as geo-hydrological boundaries. Geo-stratigraphic structures, along with corresponding hydrological parameters, were obtained from Central Groundwater Board, India, and used in the study which was carried out over a time horizon of 4.5 years. The model parameters were fine tuned for calibration using Parameter Estimation (PEST) simulations. Analyses of the stream aquifer interaction using Zone Budget has allowed demarcation of the losing and gaining stretches along the main stem of River Ganga as well as some of its principal tributaries. From a management perspective, and entirely consistent with general understanding, it is seen that unabated long term groundwater extraction within the study basin has induced a sharp decrease in critical dry weather base flow contributions. In view of a surge in demand for dry season irrigation water for agriculture in the area, numerical models can be a useful tool to generate not only an understanding of the underlying groundwater system but also facilitate development of basin-wide detailed impact scenarios as inputs for management and policy action.

International rivers are conventionally understood as watercourses that cross national boundaries, while borders themselves are taken to be static and given – passive features over and across which riparian processes unfold. Employing such straightforward framings of international rivers and borders, academic studies and policy analyses of transboundary water governance perpetuate problematic ideas about the relevant scales and actors involved in international river conflicts and crises. Through a historical examination of the Ganges River and the Indo-Bangladeshi border, I introduce the ‘river-border complex’ as a new framework for reconceptualizing international rivers and borders as synergistic, co-constitutive and interdependent.

Jeff Malpas' concept of place as a bounded, open, and emergent structure is used in this article to understand the reasons for the differences in villagers' responses to 'artificial glaciers', or 'Ice stupas', built in two different places in the Himalayan village of Phyang, in Ladakh. Using archival material, geographic information system tools and ethnographic research, this study reveals how Phyang as a village is constituted by interacting ecological-technical, socio-symbolic, and bureaucratic-legal boundaries. It is observed that technologies such as land revenue records, and cadastral maps, introduced in previous processes of imperialist state formation, continue to inform water politics in this Himalayan region. It is further demonstrated how this politics is framed within the village of Phyang, but also shifts its boundaries to create the physical, discursive, and symbolic space necessary for projects like the Ice stupa to emerge. By examining the conflict through the lens of place, it is possible to identify the competing discursive frames employed by different stakeholders to legitimise their own projects for developing the arid area (or Thang) where the contested Ice stupa is located. Such an analysis allows critical water scholarship to understand both how places allow hydrosocial relationships to emerge, and how competing representations of place portray these relationships. Understanding the role of place in the constitution of hydrosocial relationships allows for a more nuanced appraisal of the challenges and opportunities inherent in negotiating development interventions aimed at mitigating the effects of climate change. It is also recommended that scholars studying primarily the institutional dimensions of community-managed resource regimes consider the impact on these institutions of technological artefacts such as the high density polyethylene (HDPE) pipes used to construct the Ice stupas.

The rapid expansion of cities in West Africa has implications for urban cropland. This study aimed to assess the dynamics of cropland in West African cities over time and space, to identify key drivers, and to report the effects of changing cropland on farmers and farmers’ resilience strategies. Cities studied were Accra (Ghana), Bamako (Mali), Ouagadougou (Burkina Faso), and Bamenda (Cameroon). Methodology involved multi-temporal spatial analysis of satellite images and farmer surveys. Results showed that the share of urban land covered by cropland differed in these cities, with higher shares in Accra and Bamenda, which included rainfed cultivation. Over the past 15 years, Accra has lost large shares of its farming areas, both in the inner-urban areas as well as in the fringe, whereas loss in Bamenda has been less substantial. In Ouagadougou and Bamako, where only irrigated sites were captured, cropland has shifted to the fringes but increased overall. Key drivers influencing the direction of change were official support of urban farming (or lack thereof), population pressure, and the availability of public open spaces that are not suitable for construction. In cities with decreasing cropland, implications included diminishing individual farm sizes, intensification of remaining sites, cessation of farming in the city, and the shift to other sites, which—apart from the physical availability of land and related resources—depends on social relations and informal rules.
