“…In addition to PA, the built and natural environment were studied for their associations with NCDs. Researched environmental determinants of health ranged from air pollution [ 291 , 251 ] and water quality monitoring [ 246 , 241 ] to the complex ways in which climate change impacts global health [ 259 ]. For this purpose, researchers used GNSS and satellite imagery in a variety of ways.…”

BackgroundSpace technology has an impact on many domains of activity on earth, including in the field of global health. With the recent adoption of the United Nations’ Sustainable Development Goals that highlight the need for strengthening partnerships in different domains, it is useful to better characterize the relationship between space technology and global health.ObjectiveThe aim of this study was to identify the applications of space technologies to global health, the key stakeholders in the field, as well as gaps and challenges.MethodsWe used a scoping review methodology, including a literature review and the involvement of stakeholders, via a brief self-administered, open-response questionnaire. A distinct search on several search engines was conducted for each of the four key technological domains that were previously identified by the UN Office for Outer Space Affairs’ Expert Group on Space and Global Health (Domain A: remote sensing; Domain B: global navigation satellite systems; Domain C: satellite communication; and Domain D: human space flight). Themes in which space technologies are of benefit to global health were extracted. Key stakeholders, as well as gaps, challenges, and perspectives were identified.ResultsA total of 222 sources were included for Domain A, 82 sources for Domain B, 144 sources for Domain C, and 31 sources for Domain D. A total of 3 questionnaires out of 16 sent were answered. Global navigation satellite systems and geographic information systems are used for the study and forecasting of communicable and noncommunicable diseases; satellite communication and global navigation satellite systems for disaster response; satellite communication for telemedicine and tele-education; and global navigation satellite systems for autonomy improvement, access to health care, as well as for safe and efficient transportation. Various health research and technologies developed for inhabited space flights have been adapted for terrestrial use.ConclusionsAlthough numerous examples of space technology applications to global health exist, improved awareness, training, and collaboration of the research community is needed.

“…In the last decade, some significant advances were made in the application of new techniques to determine the environmental impacts of aquaculture: geospatial technology to measure the evolution of water bodies and the extent of areas used for aquaculture [26,27], geographic information systems (GIS), and remote sensing for maintaining water resources and controlling pollution in an area [28]. On the other hand, predictive models based on numerical simulation have become important tools for assessing the impacts and interactions of open-water aquaculture systems [29][30][31][32][33].…”

We predicted small-scale hydrodynamics, including the effect of the aquaculture farming infrastructure, for a region within the group of salmon farm concessions identified in the Chilean regulation as ACS-7. The geographical region corresponds to the Caucahue Channel, composed of two branches connected by a constriction on Caucahue Island, Inland Sea of Chiloe, Chilean Patagonia. The prediction methodology considers the interaction of a regional ocean model and a high-resolution local CFD model. The model prediction was validated using available data from ADCP. We find that the Caucahue Channel is characterized by a complex circulation and hydrodynamics, including an unstable shear flow, with meanders and turbulent structures, and retention zones. Results show the aquaculture infrastructure has a non-local hydrodynamic effect. Differences in horizontal and vertical velocity can be quite significant even far from aquaculture centers, reaching up to 300% and 170%, respectively, in simulations without taking its effects into account. The useful characteristics of this predictive approach and its potential use in particle tracking and species diffusion prediction allow for the use of projecting as a tool for strengthening the environmental and productive management of this industry.

“…Subramani et al (2012) studied on Coonoor Taluk's groundwater quality using GIS, which is located in Nilgiri district, India [22]. Maynar Babu et al (2014) determined water quality parameters for drinking water standards using standard water quality procedures and prepared spatial distribution maps in Arc GIS environment [23]. Yang and Jin (2010) investigated the use of spatial regression to evaluate the impacts of watershed characteristics on stream NO3NO2-N concentration in the Cedar River Watershed, Iowa [25].…”

This study involves the analysis of water resources pollution data using Geographic Information System (GIS), which is a subset of the purposes such as: study on the status (situaion) of the aquifer, the natural and man-made effects on aquifer quality, evaluation and investigation of quality monitoring results of Ardabil aquifer, study on quality limitations by comparing the results of analysis of wet and dry seasons from water resources with selected standards. Therefore, samples were collected from76 wells, in this region, for the purpose of the aquifer water quality assessment, identification of changing process of pollution and statistical analysis of quality parameters included NTU, TDS, Nitrates and Chloride. Afterwards, maps for each parameter were produced in the geographic information system (GIS) using scientific methods. Thereupon, situation and condition of water quality was measured by quality mapping index of NSFWQ and was applied for whole the basin. This maps and database, which were created by the software, provide and offer an obvious view of what happened in the study area. As a result, it could be applied for a better management of these water resources and planning to prevent further pollution, by relevant organizations.
