This case study describes the Cape Agulhas Municipality's (CAM) transition toward a "Smart City 2.0" by implementing a smart groundwater monitoring and management system. To replace costly and inefficient manual monitoring of boreholes and reservoirs, CAM deployed a municipal-wide LoRaWAN Internet of Things (IoT) network. The project, piloted in Suiderstrand, uses real-time sensors and variable speed drives (VSDs) to improve resource oversight, reduce operational costs, and lower carbon emissions.

This briefing explores how blockchain technology can enhance the cybersecurity of the electrical grid, particularly as the proliferation of Internet-connected devices increases vulnerabilities. It details the inherent security features of blockchains, their application in mitigating IoT and data communication risks, and the emerging challenge of cryptographic key mismanagement.
