“…This area of research can be accelerated with citizen science contributions to the advancement of MISH. Lowcost technology and robust practical design are crucial for facilitating citizen science [45]. Five of the proposed systems in Table 1 utilize expensive spectrometers, costing hundreds or thousands of USD [25,30,31,39,40].…”

Nutrient monitoring in Micro Indoor Smart Hydroponics (MISH) relies on measuring electrical conductivity or total dissolved solids to determine the amount of nutrients in a hydroponic solution. Neither method can distinguish concentrations of individual nutrients. This study presents the development and testing of a novel spectroscopic sensor system to monitor nitrogen changes in nutrient solutions for MISH systems. The design phase determined that using an inexpensive AS7265x Internet of Thing (IoT) sensor in a transflective spectroscopic application could effectively detect small fluctuations in nitrogen concentraation. Next, a novel transflective sensor apparatus was designed and constructed for use in a MISH system experiment, growing lettuce over 30 days. Two solution tanks of different sizes, 80 L and 40 L, were used in the deployment of the system. Samples from each tank were analyzed for nitrogen concentration in a laboratory, and multilinear regression was used to predict the nitrogen concentrations using the AS7265x 18 spectral channels recorded in the sensor system. Significant results were found for both tanks with an R2 of 0.904 and 0.911 for the 80 and 40 L tanks, respectively. However, while the use of all wavelengths produced an accurate model, none of the individual wavelengths were indicative on their own. These findings indicate that the novel system presented in this study successfully and accurately monitors changes in nitrogen concentrations for MISH systems, using low cost IoT sensors.

“…This could lead to improved model parameterisation and validation of other datasets (for example, remote sensing products), but whether mass deployments of low-cost sensors eclipse any potential loss of precision compared to commercial instrumentation is a vital consideration. Corbari et al (2022) found that highdensity, low-cost irrigation monitoring could detect fine-scale soil moisture variability missed by satellite data retrieval. Other specific services include monitoring the effects of Natural Flood Management schemes (see a later section), which are often localised and site-specific.…”

Progress in Physical Geography: Earth and Environment

This editorial reports on a horizon scan exercise that was undertaken to identify new frontier topics, new or emerging themes/concepts, or new philosophical questions of relevance to physical geography. Researchers with broad geographical and disciplinary scope, all of whom were members of the journal's editorial board or editorial advisory board, were invited to join a horizon scan panel. The horizon scan Chair canvassed panel members for ideas, resulting in an initial 32 independently proposed topics. Similar topics were merged by the Chair, and panel members were then invited to vote on and score anonymously the remaining 28 topics, bearing in mind the perceived importance/relevance and novelty for the discipline. The final ranking and sifting phase produced a list of 12 topics, which were categorised as being either new study areas or new epistemological frameworks for physical geography. In this editorial, we outline these 12 topics, some of which have been inspired by developments outside of the discipline, but we identify how potentially fertile contributions could be added by physical geographers. We discuss how new studies of extreme event geographies, the impacts of compound stressors, cross-system pollution and toxicity, the geomorphological basis of zoonoses, ancient environmental DNA, the projection and visualisation of landscape futures, and planetary sciences can all benefit from additional physical geography perspectives. We then consider the ways in which physical geographers may engage further with new approaches in personalised and internet-of-things monitoring, artificial intelligence, innovative technologies for teaching physical geography, the study of human-climate impacts, and the raising of the profile of physical geography thinking alongside other knowledge forms. We encourage more physical geographers to apply their unique skillsets and ways of thinking to these topics. The journal will welcome new submissions, or proposals for special issues, that address these topics from physical geographers and their colleagues.

“…An overview is depicted in Figure 6, which highlights the distribution and frequency of the remote sensing methods across multiple research works for analyzing water quality. Predominantly, most of the studies involving remote sensing methodologies are concentrated on utilizing spatial and temporal data of Landsat Satellite [8], [11], [27], [67], [83], [121]. Other notable studies explored remote sensing techniques for monitoring water bodies include Sentinel Satellite [45], [57], [82], [83], [83], smartphone Camera Applications for Remote Sensing [15], [63], [70], Lidar [35], and Unmanned Aerial Vehicle (UAV) [65].…”

In recent years citizen science emerged as apromising technology in environmental science and hy-drology with the potential to overcome the lack of in-situ measurements and create efficient ecosystems. Thispaper provides an up-to-date systematic literature reviewof applications of citizen science technology in water qual-ity monitoring and estimation. A bridge between citizenscience and remote sensing will be established to providea sound framework for comprehensively discussing thevarious approaches and applications. A scrutinizing of var-ious water quality parameters and associated measurement& estimation methods is provided, delving into variousremote sensing systems (microwave and optical systems)and imaging techniques (hyperspectral and hyperspectralmethods). A special interest is focused on reviewing existingrelevant crowd-sourcing mobile apps such as EyeOnWater,HydroColor, EnviObserver, Sechhi App, Hydro Crowd,and SIMILE-Lake monitoring, detailing their workingmechanisms, algorithms, data acquisition processes, usedsensors, and measured water quality parameters. Finally,the paper summarizes key knowledge gaps, challenges andpromising directions in this research field.
