Yatta Canal is situated in Yatta division, Machakos district about 100 km from Nairobi along Thika- Garissa road. It is about 60 Km long and supplies water for domestic, livestock and irrigation use. Over the years, the water supply has been unreliable especially during dry season leading to conflicts between upstream and downstream consumers. Sometimes the Government has been forced to intervene to restore order. The study aimed at assessing the use of Yatta canal, based on the principles of Integrated Water Resources Management (IWRM) which stipulates efficient use of water and involvement of all stakeholders in decision making for sustainability. Based on this concept, it was established that the current water demand outstrips supply and that there is inefficient water use especially for irrigation. Waterallocation process favours landowners, and stakeholders are not fully involved in planning, management and development. Further, women’s participation in decision-making is minimal. There is no environmental voice during water allocation and thus the reserve/ base flow in the canal has not been maintained. This means that IWRM concept has not been practiced and this has resulted to conflict among various water users. As Yatta canal gets water from Thika river, there is need to establish Thika river basin water users association where stakeholders can influence decisions on water allocation and management. This will create a forum to discuss efficient water use at all levels and promote internal policing to ensure fair allocation, thus minimizing conflicts and promoting the IWRM concept.

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. Integrated Water Resources Management (IWRM) recommends, among other things, that the management of water resources systems be carried out at the lowest appropriate level in order to increase the transparency, acceptability and efficiency of the decision-making process. Empowering water users and stakeholders transforms the decision-making process by enlarging the number of point of views that must be considered as well as the set of rules through which decisions are taken. This paper investigates the impact of different group decision-making approaches on the operating policies of a water resource. To achieve this, the water resource allocation problem is formulated as an optimization problem which seeks to maximize the aggregated satisfaction of various water users corresponding to different approaches to collective choice, namely the utilitarian and the egalitarian ones. The optimal operating policies are then used in simulation and compared. The concepts are illustrated with a multipurpose reservoir in Chile. The analysis of simulation results reveals that if this reservoir were to be managed by its water users, both approaches to collective choice would yield significantly different operating policies. The paper concludes that the transfer of management to water users must be carefully implemented if a reasonable trade-off between equity and efficiency is to be achieved.

This paper seeks to complement ongoing discussions around water allocation by offering an analytic framework for examining the evolution of paradigms for water allocation in river basins. It traces this evolution from the hydraulic paradigm through to Integrated Water Resources Management (IWRM) and the current water security paradigm. Using a society-science-practice interaction perspective, the paper draws attention to the governance processes of water allocation that underlie these paradigms using examples from river basins in southern Africa. It is argued that the process of allocating water resources is often influenced by societal priorities and values that do not necessarily result in maintaining ecosystem health and integrity. The efficacy of water allocation depends on the extent to which implementation takes into account the socio-political dynamics associated with collective action involving multiple water users. While paradigm shifts provide windows of opportunity for strengthening legislation, the mere adoption of paradigms should not be taken as a panacea for addressing challenges associated with water allocation in river basins. This is especially relevant for several countries in southern Africa that are undertaking water reforms with the view of strengthening allocation of water resources at basin scale.

In mid-1999, the Walt Disney Company and the Hong Kong Government were involved in intense discussions about the possibility of building the Hong Kong Disneyland theme park on Lantau Island. This case presented detailed information about the proposed theme park and the associated decision making process with a particular emphasis on sustainable development. It also lays out the characteristics of the Hong Kong Government and Hong Kong people that might have played a role in decision making. The case includes A and B parts concerning corporate and government decision making. It firstly summarizes the negotiation process between Disney and the Hong Kong Government, and considered the environmental impact on Hong Kong. The difficulties faced by governments in making decisions about this highly visible large-scale project are described. It then explains the rationale of the government decision, which illustrates how governmental structure and culture affect the decision making process. In the end, it showed improvements in Hong Kong Disneyland with respect to sustainable management and development.

The core executive is a new concept replacing the conventional debate about the power of the prime minister and the Cabinet. It refers to all those organizations and procedures that coordinate central government policies, and act as final arbiters of conflict between different parts of the government machine. In brief, the ‘core executive’ is the heart of the machine. The chapter reviews the several approaches to studying the British executive: prime ministerial government; prime ministerial cliques; Cabinet government; ministerial government; segmented decision-making; and bureaucratic coordination. It then discusses several ways forward by developing new theory and methods. The Afterword discusses the core executive as interlocking networks, and the fluctuating patterns of executive politics.

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.

Demand Information

Under the current administrative system (AS) in China, the water resources governor allocates limited water resources to several users to realize the utility of water resources, leading to a principal–agent problem. The governor (referred to as the principal and she) wishes to maximize water resource allocation efficiency, while each user (referred to as the agent and he) only wishes to maximize his own quota. In addition, the governor cannot know water demand information exactly since it is the water users’ private information. Hence, this paper builds an ex ante improved bankruptcy allocation rule and an ex post verification and reward mechanism to improve water allocation efficiency from the governor’s perspective. In this mechanism, the governor allocates water among users based on an improved bankruptcy rule before the water is used up, verifies users’ information by various approaches, and poses a negative reward to them if their information is found to be false after the water is used up. Then, this mechanism is applied to Huangbai River Basin. Research results show that the improved allocation rule could motivate users to report demand information more honestly, and ex post verification could motivate water users to further report their true information, which, as a result, could improve the water allocation efficiency. Furthermore, this mechanism could be applied to the allocation of other resources.
