This paper presents a review of records of pollen and botanical macroremains of a selection of food plants from late and post-medieval cesspits (12th century-19th century ad) in the Netherlands and northern Belgium. The presented data demonstrate that several food plants remain largely invisible in the macrobotanical records. These are all plants from which the flowers or flower buds (Borago officinalis, Capparis, Carthamus tinctorius, Crocus sativus, Syzygium aromaticum) or leaves (Anthriscus cerefolium, Spinacia oleracea) are eaten, or that are typical components of honey (Cistus). As a result, little is known about the import or local production and consumption of these food plants in these times. This review now shows that past use of some of these plants is reflected in the pollen assemblages of (post-) medieval cesspits. For the first time, a large archaeobotanical dataset is presented, including pollen, providing information on the past use of these plants between the 12th and 19th century ad in the Netherlands and Belgium.

Soil movement may be induced by a wide variety of natural and anthropogenic causes, which are detectable in the local scale, but may influence the movement of the soil over vast geographical expanses. Space borne interferometric synthetic aperture radar (InSAR) measurements of ground movement provide a method for the remote sensing of soil settlement and uplift over wide geographic areas. Based on this settlement and uplift evaluation, the assessment of the potential damage to architectural heritage structures is possible. In this paper an interdisciplinary monitoring and analysis method is presented that processes satellite, cadastral, patrimonial and building geometry data, used for the calculation of settlement and uplift damage to architectural heritage structures in Belgium. It uses processed InSAR data for the determination of the soil movement profile around each case study, of which the typology is determined from patrimonial information databases and the geometry is calculated from digital elevation models. The impact on the historic structures is calculated from the determined soil movement profile based on various soil-structure interaction models for buildings. The resulting damage is presented in terms of a numerical index illustrating its severity according to different criteria. In this way the potential soil movement damage is quantified in a large number of buildings in an easily interpretable and user-friendly fashion. The processing of InSAR data collected over the previous 3 decades allows the determination of the progress of settlement- and uplift-induced damage in this time period. With the integration of newly acquired and more accurate data, the methodology will continue to produce results in the coming years, both for the evaluation of soil settlement and uplift in Belgium as for introducing related damage risk data for existing architectural heritage buildings. Results of the analysis chain are presented in terms of potential current damage for selected areas and buildings.
