Since its earliest applications in the 1970s, geophysical survey has been applied increasingly in Belgian archaeology. This was particularly the case within Flanders over the past decade. Academic archaeological research has played a fundamental role in disseminating available techniques, such as electrical resistance and magnetometer survey, and in advancing the use of electromagnetic induction- and ground penetrating radar instruments for archaeological prospection specifically. However, the dissemination of this expertise remains in its infancy and adoption in Brussels and Wallonia lingers behind. Although Flanders has seen a strong increase in such surveys over the past decade, the share that geophysical techniques take up in development-led archaeology pales to significantly wider used invasive prospection methods. Both a lack of tradition in archaeological geophysics as well as the dominance of systematic trial trenching as a prospection method underlie this slow uptake of geophysical approaches in development-led archaeology. In contrast, geophysical survey does play a significant role in academic (landscape) archaeological research and in the investigation of archaeological sites for scheduling. Within this general situation, the use of geophysical methods in Belgium is geared primarily towards specific expected types of sites, but, within the heterogeneous geological landscape, spans a wide range of environments.While progress has been made continually over the past decade, much room remains for further optimisation of the use of geophysical methods in Belgian archaeology. Here, improving protocols for the integration of complementary, invasive and non-invasive, survey methods adapted to the diverse geological and archaeological circumstances remains a key challenge. To enable these advances, current efforts to provide such a methodological framework, along with existing expertise across the nation, have to be disseminated beyond academic circles through initiatives, such as dedicated (post-)academic training and inclusion of both archaeologists and archaeological geophysicists. Hereby, the consolidation of a robust legislative framework, adhering to EAC guidelines, is required for implementing geophysics in (development-led) archaeology sustainably, similar to e.g. trial trenching. This should safeguard the quality, archiving, accessibility, and interoperability of resultant data.
