“…A brief review of the water-climate studies in the SADC showed that most water and climate studies in the region are conducted separately (Brewis et al 2019) with a few exceptions by Derrick Ngoran et al (2015), Kusangaya et al (2014) and Liehr et al (2017) that seek to address both water and climate jointly. South Africa has carried out most research on water-resource management than any other country in the SADC (Masia & Erasmus 2013;Mckenzie & Wegelin 2009), followed by the impact of climate change (Du Plessis 2017) and groundwater modelling (Abiye 2016). Studies conducted in Namibia (Angula 2010;Jury & Engert 1999;Kluge et al 2008;Liehr et al 2017;Mbaiwa 2004;Newsham & Thomas 2011) focus more on the prediction of the impact of climate and water scarcity because of the arid nature of the country.…”

The scholarly theme of the book lends itself to the discipline of earth and atmospheric sciences, with a specific focus on water-climate studies. The book is a scholarly discourse by researchers in the natural sciences, including hydrologists, climate scientists, environmental engineers and water scientists. The purpose of the book is to address the limited complementarity between the water and climate studies, which is crucial in promoting scientific research that informs policy decisions and the implementation of water-security plans. The chapter contributions were sourced from researchers in the project -'Water Security and Climate Adaptation in Southern Africa' at the North-West University, and the research chair network linked to the United Nations Educational, Scientific and Cultural Organization (UNESCO) Chair on Sustainable Water Research for Climate Adaptation in Arid Environments, based at the Namibia University of Science and Technology. The chapters were selected to represent water-climate models and policy research conducted in different river basins in arid and semi-arid environments. Therefore, the water-climate management tools highlighted in this book include General Circulation Models (GCMs), Coupled Model Inter-comparison Project Phase 5 (CMIP5), Soil and Water Assessment Tool (SWAT), Africa Flood and Drought Monitor (AFDM), Extreme Precipitation Events (EPEs), R ClimDex, Mixed Strategy Game Models, Standard Precipitation Indices (SPIs), Water Evaluation and Planning (WEAP) System, Penman Calculator and Saturated Volume Fluctuation (SVF).Four of the nine chapters in this book contain material representing substantial reworking of the primary research and modelling for higher degree studies done at the University of Zambia and the Namibia University of Science and Technology. One chapter is a review of previous studies, and the remaining eight are based on river basin research and modelling projects by researchers from different institutions. As a whole, the book contains more than 50% original content, not published before, and no part of the book has been plagiarised.

“…Some of the other applications along with their advantages of using smart metering can be better understand from Figure 7. Masia et al [94] have shown usage of a smart meter for reducing NRW losses and demand management in WDS of Gauteng, South Africa. Smart water metering has created awareness among the 40% of the population regarding excess water consumption by them.…”

According to the United Nation’s World Water Development Report, by 2050 more than 50% of the world’s population will be under high water scarcity. To avoid water stress, water resources are needed to be managed more securely. Smart water technology (SWT) has evolved for proper management and saving of water resources. Smart water system (SWS) uses sensor, information, and communication technology (ICT) to provide real-time monitoring of data such as pressure, water ow, water quality, moisture, etc. with the capability to detect any abnormalities such as non-revenue water (NRW) losses, water contamination in the water distribution system (WDS). It makes water and energy utilization more efficient in the water treatment plant and agriculture. In addition, the standardization of data format i.e., use of Water Mark UP language 2.0 has made data exchange easier for between different water authorities. This review research exhibits the current state-of-the-art of the on-going SWT along with present challenges and future scope on the mentioned technologies. A conclusion is drawn that smart technologies can lead to better water resource management, which can lead to the reduction of water scarcity worldwide. High implementation cost may act as a barrier to the implementation of SWT in developing countries, whereas data security and its reliability along with system ability to give accurate results are some of the key challenges in its field implementation.
