Natural resource management requires reliable and timely information available at local, regional, national, and global scales. Geo-informatics, by remote sensing, global navigation satellite systems, geographical information systems, and related technologies, provides information for natural resource management, environmental protection, and support related to sustainable development. Geo-informatics has proven to be a powerful technology for studying and monitoring natural resources as well as in generating predictive models, making it an important decision-making tool. The manuscripts included in this Special Issue focus on disciplines that advance the field of resource management in geomatics. The manuscripts showcased here provide different examples of challenges in resource management.

The National Collection of Arachnida (NCA) was established in 1976 at the Agricultural Research Council – Plant Health & Protection (ARC-PHP) in Pretoria, South Africa. This collection forms part of South Africa’s National Assets, which the ARC manages and maintains on behalf of the Department of Agriculture, Forestry and Fisheries (DAFF) and the Department of Science and Technology (DST). The specimen holdings of the NCA contain a wealth of associated taxonomic, biological and geographical information. Currently the collection is managed by a dedicated collection manager responsible for the day-to-day running of the collection assisted by one research assistant. It is utilized for various research activities and knowledge generation in the fields of agriculture and natural resource management. The specimens are preserved using 75% alcohol and held in a double vial method in order to maximize protection of the specimens against evaporation and breakage. Hand-written catalogue books are still used to record and allocate a unique NCA – AcAT number for each specimen. This number links to all primary data recorded for the specimen. Furthermore, the data associated with the specimens are digitized according to Darwin-Core guidelines in an Structured Query Language (SQL) relational database. The database was developed by the ARC-Information Technology services. The entire NCA presently houses approximately 77,780 catalogue entries representing more than 233,300 specimens from six Arachnida orders. The NCA is made up mainly of reference specimens, but also has a type specimen collection of newly described species. The type collection currently contains 1,018 type specimens representing 321 species in 136 genera and 42 families. Of these, 207 specimens are holotypes. The type collection is housed separately from the reference collection and was recently moved to a newly acquired fireproof cabinet. Further planned activities include taking photos of all type specimens using a Zeiss V.16 Zoom microscope so that all type holdings are fully digitized. This will allow the implementation of an electronic loans system. Updating of the types list in the collection will facilitate availability for the wider community. The NCA provides support for key services such as the identification of arachnid predators that have an impact on agricultural production and bio-security as well as a specimen identification and advisory service to government, farmers, industry, researchers, students and the public. These services are essential for research projects on biosystematics and relevant related fields such as conservation, decision-making, agriculture and natural resource management.

The Special Issue Community, Natural Resources, and Sustainability seeks to engage in an interdisciplinary and international dialogue on the interrelationships of society, natural resources, and sustainability at the community level. In addition to introducing the twelve research articles published in this collection, we provide an overview of the existing literature on community and natural resource management, mainly through a review of previous reviews and a bibliometric analysis. While this literature is dominated by studies on various aspects of community-based natural resource management, the present Special Issue showcases multiple thematic areas of research that collectively contribute to a more complete understanding of the community-resources-sustainability linkages. Our review also pinpoints important gaps in existing meta-analyses and bibliometric analyses. Promising directions for future research are highlighted.

This paper examines some of the features that have made maps into an essential and traditional tool used by all those involved in the management of natural resources. A main competency of natural resource managers and geographers is map making, along with map reading and map usage, as it allows a vision to be constructed, aiding the understanding of bio-cultural ocean, riverine and landscapes and helping to put them into perspective. I argue that the prominence of mapping in natural resource management comes from a topokinetic quality of knowledge generation and a visual character of knowledge reproduction. I also argue that mapping is a pedagogical device not exclusive to western ontological tradition, and that these features have made mapping a favorite episte-mological translation tool.

AbstractThe processing of measurement data from satellite constellations such as Global Navigation Satellite Systems (GNSS), including the well-known Global Positioning System (GPS), have been successfully applied to virtually all areas of geophysical sciences. In this work, a method is described where Geographical Information Systems (GIS) are employed to build hourly ionospheric Total Electron Content (TEC) maps for 2011 over the southern Iberian Peninsula. The maps used GPS-derived geometryfree linear combinations attained from station data from the Algarve, Alentejo (Portugal), Andalusia, Murcia and Valencia (Spain) regions. Following the construction of the ionospheric maps, it was possible to relate these results to natural phenomena. The observed phenomena included diurnal and seasonal variations: daytime TEC maxima, nighttime TEC peaks, summer TEC value decreases, and spring and fall TEC maxima. After validation of these periodic phenomena, detection of non-periodic changes, such as solar flares and tectonic interactions with the ionosphere were attempted. The results showed a TEC increase following a selected solar flare event and a potential TEC build-up prior to the 2011 Lorca earthquake. Further studies could open up the possibility of building early warning systems. The presented methods, based on available software packages, are also of value in monitoring the effect of the ionosphere on radio signals, satellite and mobile communication, power grids, and for accurate GNSS navigation.
