Key Issues

South Africa introduced a visionary policy for water resource management in 1998. The South African National Water Act (Act 36 of 1998) contains several innovative mechanisms with the potential to transform water resource management within the country and abroad. The Reserve is one of these innovations, guaranteeing a basic water requirement for both human needs and ecosystem health. This article discusses the process of Reserve determination and implementation in South Africa and identifies challenges and opportunities for successful implementation. Based on the perceptions of 28 water managers, consultants, and researchers, the key issues and recommendations for improving implementation are presented. The major findings indicate that political support, the capacity of the implementing organization, supporting policies, strong linkages between policy actors and effective monitoring programs are key issues in the successful implementation of sustainable development policy mechanisms.

Water Resource Conservation

The study examined the adoption of water conservation practices and challenges encountered by smallholder farmers in water resource conservation in Enyibe, Ermelo South Africa. The data were collected using structured questionnaires, observation and focus group discussion. Frequency, mean and logistics regression were used for data analysis. Age (β=1.238), sex (β=-1.497), level of education (β=-1.062), access to irrigation facilities (β=1.690), payment of water tariff (β=1.369) and agricultural extension advice (β=-.631) were significant and associated with adoption of water conservation practice. The identified constraints in the adoption process were inadequate technical guidelines, financial, government policies, and inadequate knowledge of water conservation practices. There is need to improve information, showcase the benefits of water conservation, and ensure maintenance of water conservation infrastructure. Concerted effort must be made to establish robust database on water resource conservation and sources of water utilised in the area. Keywords: Sustainable, water conservation, constraints, adoption

Development Goals

It is increasingly acknowledged that the water-energy-climate change (WECC) nexus is one of the synergies that pose a significant risk to achievement of sustainable development goals (SDGs), specifically numbers six, seven and thirteen. There are suggestions that climate change outcomes such as increased temperature and drought episodes have implications for water availability, which in turn affects energy production in countries dependent on hydropower, pump-storage or coal-generated electricity, including South Africa. This development therefore calls for improved understanding of how to effectively manage the challenges that arise from this nexus, to mitigate the impacts it may have on achieving the associated SDGs. This study, which is based on an in-depth appraisal of existing developments, assessed the potential of the integrated water resource management framework in understanding the WECC nexus and its implications for South Africa’s sustainable development endeavours, particularly in the context of water resource management and utilisation. The study revealed South Africa’s lack of integrated, effective, and efficient institutions and policy framework to comprehensively manage the challenges emanating from this nexus. It identified an urgent need to develop systems and processes through which South Africa can handle the challenges as well as capture the benefits that may be obtained from this nexus.

The author presents a vision of the main factors of the water resource crisis in two BRICS countries, South Africa and Russia, concretely in Cape Town and Crimea. Although Russia, contrary to South Africa and many other countries, disposes abundant water resources, there are areas of scarcity and arid lands, Crimea among them. In both cases under consideration poor management and planning, lack of funding, worn out infrastructure and factors of mismanagement and corruption added to natural or geopolitical causes of resent hardships. Besides improvements in above mentioned fields and general modernization of infrastructure, also desalination, complex wastewater recycling and turnover to drip irrigation are among proposals discussed.

Resource Systems

South Africa has one of the most complicated and integrated water resource systems in the world involving numerous interlinked river systems and major interbasin transfer schemes. The management of the various schemes has become a key issue over the past 15 years resulting in the development of sophisticated systems models which are now used to analyse and operate all of the country's major schemes. The models have been developed through a partnership between the Department of Water Affairs and Forestry in association with several of the country's consultants specialising in this area of expertise. The models have now reached a stage where they are considered to be both practical and sufficiently robust to use in other parts of the world. Australia and South Africa are quite similar in many respects with regards to the water resources and climate. Both countries share the same problem of large arid or semi-arid areas together with areas where the local water resources are insufficient to meet the existing or predicted future demands. Environmental considerations are also of major importance in both countries which in turn necessitates the effective use of the available resources before any new resources can be developed. In order to use the available water effectively much effort has been placed on various aspects of Water Demand Management in order to reduce leakage and excessive consumer use. It is also necessary, however, to ensure that the raw water resources are managed in an efficient and practical manner - something that is often easier said than done. This paper provides general details of the system analysis techniques that have been pioneered in South Africa and discusses the most recent developments that can be used to assist water resource managers in the analysis and planning of their water resource systems.
