Given a growing global population and shift to embrace the blue economy, a need for marine spatial planning (MSP) has emerged in South Africa to sustainably resolve the rising conflicts over the use of marine and seabed resources and services. A well-developed marine spatial plan yields numerous ecological, social and economic benefits. These are achieved through mediating between spatially conflicting economic drivers' interests (e.g. commercial fishing, tourism, mining), preventing their activities from compromising thresholds of an environment's sustainability. Within the MSP framework, high-resolution geospatial datasets are required to document and describe the seabed in the highest possible detail. At any scale, integrated analysis of seabed geomorphology and habitats is anticipated to greatly improve the understanding of ecosystem functioning from a multidisciplinary perspective, whilst improving MSP procedures and management of marine space. South Africa is the first of few African countries to have an approved and implemented MSP framework, but is still somewhat behind globally in implementing large-scale regional hydroacoustic surveys to cover the country's vast offshore territory. The deficiency of hydroacoustic surveys is perhaps due to a relative lack of funds and poor communication about the value of multibeam echo-sounder (MBES) derived data, whilst marine geoscience remains a scarce skill in the country. This review paper presents a geological perspective of MSP and explores (1) the value that seabed mapping offers MSP specifically and (2) the need to increase seabed mapping with MBES, using a recently initiated project from the South African east coast as a case study.

In this paper my thought experiment leads me to posit that South Africa's environmental governance often results in what I term "hollow environmentalism". This term describes the inevitable long-term outcome of promulgating laws and policies that are idealistic and seem symbolic and that at times fail to achieve their intended objectives or environmental promise. On a narrower scale, hollow environmentalism can also manifest when such symbolic environmental laws and policies lead to judicial decisions that lack substantive ecological justifications, perhaps even resembling symbolic judgments. I substantiate this argument through four key considerations. I commence with a reality check on environmental governance, emphasising that the state is not a neutral actor, necessitating closer scrutiny of state decisions. This leads me to the conclusion that governance stands at a critical juncture. I argue that the symbolic nature of our environmental laws, broadly speaking, often makes it challenging for the state to fully meet the lofty ideals it presents, thereby also complicating court decisions in these matters. Next, I align my thoughts with recent literature on adjudication in the context of the climate crisis. This literature stresses the need for courts to be bold and innovative in their judicial roles, given the precarious nature of stabilising environmental disputes. In the penultimate section I bring the discussion to a close by suggesting two interconnected possibilities to address hollowness in the face of climate change: "sunsetting" and "substitution".
