Growing demand for water leads to increased competition between water users. A holistic, participatory and decentralized water management approach is promoted to reach a fair allocation mechanism between competing water uses. Domestic political discourse has a strong influence on water policies being developed.

Water is a critical resource for mining operations, as it is for many other water users within any local catchment. With operations often located in water scarce areas, mining companies are increasingly experiencing competition for access to water resources. Concerns over the potential adverse impacts of mining on these shared resources has resulted in the sectors water management approach and practices being challenged by external stakeholders including local communities. This paper overviews the drivers that have resulted in the mining sector expanding its approach from water management within the operational fence line to catchment water stewardship, some of the major obstacles to continued progress and the related needs for guidance, research and research applications.

Allocating finite water resources between different water uses is always a challenging task. Searching for a solution which satisfies the water needs (requirements) of all water users without compromising the water requirements of river ecosystems calls for analyzing different water management options and their expected consequences. Water management balances are usually used for comparison of water resources with the needs of water users. When aquatic and water dependent ecosystems are considered in a similar manner as other users, searching for the optimum water resources allocation, without neglecting requirements of the natural environment, is possible. This paper describes basic modeling assumptions and methodological solutions, which allow for taking into account some tasks related to the protection of aquatic and water dependent ecosystems. The water balance model, developed for a catchment comprising the Warta Mouth National Park, was applied to find out whether supplying adequate amounts of water for conservation (or restoration) of wet meadows and wetland habitats in the area is possible, while still satisfying the demands of other water users.

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.

This study aims to offer a comprehensive assessment of the impacts of policies and institutional arrangements on irrigation management performance. The case study, the Gezira Scheme, has witnessed a significant decrease in water management performance during recent decades. This situation led to several institutional changes in order to put the system on the right path. The main organizations involved in water management at the scheme are the Ministry of Irrigation & Water Resources (MOIWR), the Sudan Gezira Board (SGB), and the Water Users Associations (WUAs). Different combinations from these organizations were founded to manage the irrigation system. The evaluation of these organizations is based on the data of water supply and cultivated areas from 1970 to 2015. The measured data were compared with two methods: the empirical water order method (Indent) that considers the design criteria of the scheme, and the Crop Water Requirement (CWR) method. Results show that the MOIWR period was the most efficient era, with an average water surplus of 12% compared with the Indent value, while the most critical period (SGB & WUAs) occurred when the water supply increased by 80%. The other periods of the Irrigation Water Corporation (IWC), (SGB & MOIWR), and (WUAs & MOIWR) had witnessed an increase in water supply by 29%, 63%, and 67% respectively. Through these institutional changes, the percentage of excessive water supply jumped from 12% to 80%. Finally, the study provides general recommendations associated with institutional arrangements and policy adoption to improve irrigation system performance.

Genuine inclusive participation in the self-governance of communal irrigation systems remains a challenge. This article analyses the mechanisms of participation in irrigation water users’ associations (WUAs) with focus on women as leaders of those organizations by drawing on cases from a comparative, multicase mixed-method study in Ethiopia and Argentina. After having being a topic for decades in gender and development debates, in many irrigated areas of the world, WUAs continue to be male dominated at all levels, especially in influential positions. Findings in this article suggest that despite large socio-economic and cultural differences, the current water management systems in both research locations reinforce problems of unequal gender participation; women have more obstacles and constraints in establishing equal access in membership, participation, and decision making in irrigation management. The lack of inclusive participation and the low representation of women in leadership roles lead to WUAs being poorly rooted in their community of users. Incomplete social rootedness of WUAs jeopardizes their effectiveness and equality in water management and, as a result, affects long-term sustainability. Through analysis of empirical data of communal small-scale irrigation systems in both countries, the article discusses who participates, how and why they participate, and the reasons for low numbers of women in leadership roles within the WUAs. Finally, the article reflects on possible enabling conditions that could foster inclusive participation, increase the quantity and capacity of women in management and leadership roles, and the benefits this may bring to sustainable irrigation systems.

San Antonio Water Systems (SAWS) developed its H2Oaks aquifer storage and recovery project in response to pumping restrictions set on its primary source of water supply, the Edwards Aquifer. The H2Oaks project pumps water from the Edwards Aquifer during wet years and transports it to the H2Oaks project site, where it is injected into the Carrizo-Wilcox aquifer for storage. Stored water is withdrawn to meet municipal demand when restrictions on Edwards Aquifer pumping are in place. Although created for the purpose of securing supplies for SAWS, the H2Oaks project became a centerpiece for regional water management. Storage is used during drought to mitigate impacts on pumping while ensuring minimum springflows needed to protect endangered species in the Edwards aquifer. Currently, the project stores over 176,000 acre-feet of water. This case study traces the development of the H2Oaks project from the passage of the Edwards Aquifer Act to the project’s current implementation. The H2Oaks project demonstrates the potential for groundwater recharge projects to store water as protection against drought conditions. It also demonstrates how storage by one entity can support water management needs across the broader community of water users.

The chapter assesses the notion of local scale and decentralization that emanates from the IWRM principles. Evaluation of the benefits of decentralization was done through the political ecology lens that critically examines fairness and power struggles across spaces. Sanyati catchment was used to draw empirical evidence in light of the theoretical expectations of decentralization towards catchment water security. Qualitative approach was used to collect data. Interviews were the main sources of data collection. The findings showed that decentralization has failed to produce the desired results compared to what is assumed in the dominant narrative that highly esteems the decentralization management approach. The chapter showed that what brings results are not local scales and suggests that probably fair and transparent resource distribution and allocation at any scale may bring about water protection that does not trigger the tragedy of the commons.
