This article traces the history of integrated water resources management (IWRM) in South Africa since the 1970s. It examines IWRM according to its three common pillars, which are also reflected in South Africa's National Water Act: economic efficiency, environmental sustainability, and equity. The article highlights how the principles of economic efficiency and the environment as a user in its own right emerged under apartheid, while equity was only included in the post-1994 water policies, with evolving influence on the other two principles. In 2013, the Department of Water Affairs overcame the widely documented flaws of IWRM by adopting developmental water management as its water resource management approach, aligning with the political and socio-economic goals of South Africa's democratic developmental state.

Emerging approaches to water resources development and management typically highlight equity and productivity as two main objectives. In the context of integrated water resources management within a river basin, managers and stakeholders often need a comparative assessment of different options for water augmentation and/or allocation. Pitting such options against predefined objectives, such as equity and productivity, requires an assessment of the effects that available options will have on these objectives. Available documentation indicates that not only does the interpretation of such objectives vary widely, but also the available methods for assessing equity and productivity run into significant limitations in the availability of adequate data. This limitation has largely kept decision makers from gaining a comprehensive overview of equity and productivity scenarios, whether within or across sectors, that could facilitate better-informed decisions. To address this methodological gap, this article scrutinizes different notions associated with equity and water productivity, and limitations in prevalent assessment methods with the view to develop and demonstrate pragmatic methodologies for assessing equity and productivity in data-scarce contexts. The discussion and findings are based on a review of relevant literature and empirical and consultative research work in the Olifants River basin in South Africa. The demonstrated methodologies for assessing equity and productivity, besides being useful in data-scarce contexts, are insightful for initiating several policy measures and also for exploring the relationship between equity and water productivity.

The case study describes large-scale environmental change related to, and recent responses associated with, growing water scarcity in the Usangu Plains, a catchment of the Great Ruaha River in south-west Tanzania. The analysis uses outputs from two recent projects to critically examine various theories of environmental change and the ‘fit’ of new river basin management strategies to the problems found, arguing that various perspectives are worryingly at odds with each other. We find that the investigators of the two projects presented a reasonable and sufficient case of the causes of water scarcity. Yet despite efforts to disseminate scientific findings, different stakeholder groups did not agree with this case. This, we believe, was due to three combined factors; firstly highly entrenched views existed that were also based on quasi-scientific reasoning; secondly, the projects’ deliberations to date, in acknowledging their own uncertainty, were not assertive enough in ascribing causation to the various processes of change; thirdly, policy-uptake was not sufficiently managed by the scientists involved. We conclude that this complexity of the science–policy interface is a feature of integrated water resources management (IWRM) and that the norms of scientific uncertainty in the face of competing theories (held by their protagonists with greater certainty) obliges scientists to take a more active role in sensitively managing the advice-to-policy process in order to improve management of water within river basins. Thus, the paper argues, the nature of integrated water resources management is one of ‘action research’ to move towards an improved understanding of change, and of ‘action policy-advising’ to draw policy-makers into a cycle of considered decision-making.

This paper discusses the changes in water law in South Africa since the new dispensation. The focus is on the poverty dimensions of the early experiences of implementation of one of the components of the National Water Act: the establishment of Catchment Management Agencies (CMAs). From a diversity of recent experiences in decentralizing integrated water resources management, key areas emerge where future actions by the government are crucial to establish pro-poor, developmental CMAs.

This article discusses ways in which the South African Government and grassroots organizations envisage and implement democracy achieved since 1994 in the field of water resources management. The focus is on the democratic, political and economic freedom and equality in resource rights for poor black women, who are central to poverty eradication. While the new water policy and law provide an enabling framework for achieving these goals, implementation on the ground encounters both new opportunities and constraints. This is illustrated by several cases of establishing South Africa's new water management institutions: catchment management agencies and water user associations. The important nexus between state-led democratization of water resources management and bottom-up grassroots movements is also discussed. The article concludes that the Government's affirmative and targeted intervention is indispensable for redressing gender inequalities and eradicating poverty. [ABSTRACT FROM AUTHOR]

This article offers an approach to the study of the evolution, spread and uptake of integrated water resources management (IWRM). Specifically, it looks at theflowof IWRM as an idea in international and national fora, itstranslation and adoptioninto national contexts, and the on-the-groundpracticesof IWRM. Research carried out in South Africa, Zimbabwe and Mozambique provides empirical insights into the politics of IWRM implementation in southern Africa, the interface between international and national interests in shaping water policies in specific country contexts, and the on-the-ground challenges of addressing equity, redress and the reallocation of water.
