Using ArcGIS Portal to inform decision making for Integrated Coastal Management, KwaZulu-Natal

Abstract

The coastal environment is one of the most utilised for human activities; providing a diverse range of goods and services such as fisheries, water purification and coastal erosion protection. This results in the need for effective, ongoing management and informed decision making, to ensure long-term sustainability of the coastal environment. However, Goble et al. (2017) highlight that institutional knowledge and capacity are currently limited to achieve the objectives of effective coastal management. This research considers the use of ArcGIS Portal as a component of a Decision Support System (or Info-portal) for coastal management in KwaZulu-Natal, through the development of an online, interactive mapping platform. This platform offers a portal to decision makers to access and interrogate data and information, thus informing decision making. The development of this tool followed a participatory approach, and engagement with end-users throughout the process to ensure that the tool meets users’ requirements. To date, the info-portal has been well utilised by both decision makers and members of the public that are interested in the coast. It offers an excellent example of the power of a spatial tool in improving decision making.
