Ensuring taught fieldwork is a positive, generative, collective, and valuable experience for all participants requires considerations beyond course content. To guarantee safety and belonging, participants’ identities (backgrounds and protected characteristics) must be considered as a part of fieldwork planning and implementation. Furthermore, getting fieldwork right is an important step in [...]

Agricultural Sandbox NL: A national-scale database of parcel-level, processed Sentinel-1 SAR data

Vineet Kumar, Manuel Huber, Bjorn Rommen, et al.

Published: 2021-07-15
Subjects: Databases and Information Systems, Geographic Information Sciences, Remote Sensing, Spatial Science

Synthetic Aperture Radar (SAR) data handling, processing, and interpretation are barriers preventing a rapid uptake of SAR data by application specialists and non-expert domain users in the field of agricultural monitoring. To improve the accessibility of Sentinel-1 data, we have generated a reduced-volume, multi-year Sentinel-1 SAR database. It includes mean and standard deviation of VV, VH and [...]

High resolution, annual maps of the characteristics of smallholder-dominated croplands at national scales

Published: 2021-03-12
Subjects: Agriculture, Environmental Monitoring, Environmental Sciences, Geographic Information Sciences, Geography, Life Sciences, Natural Resources and Conservation, Physical and Environmental Geography, Physical Sciences and Mathematics, Remote Sensing, Spatial Science, Sustainability

Mapping the changing characteristics of Africa's smallholder-dominated agricultural systems, including the sizes and numbers of fields, is crucial for understanding food security and a range of other socioeconomic and environmental concerns. However, accurately mapping these systems is difficult because of 1) the spatial and temporal mismatch between satellite sensors and smallholder fields, and [...]

Linkage between the Forest Fires and the Meteorological Parameters during the current climatic regime using Spatial Clustering, Regression, and Combination Matrix Analysis

Manish Pandey, Aman Arora, Masood A Siddiqui, et al.

Subjects: Geographic Information Sciences, Geography, Physical and Environmental Geography, Remote Sensing, Spatial Science

The present study has been carried out to assess the spatial behaviour of forest fire count (FFC) data and Climate Forecast System Reanalysis (CFSR) derived meteorological parameters in Uttar Pradesh to explore the linkages amongst them. Ten years (2005 to 2014) of forest fire event data and of meteorological data have been analysed using GIS overlay, ordinary least square (OLS) regression, [...]

Plastic plants: Water hyacinths as driver of plastic transport in tropical rivers

Louise Schreyers, Tim van Emmerik, Thanh Luan Nguyen, et al.

Published: 2021-01-14
Subjects: Environmental Monitoring, Fresh Water Studies, Hydrology, Remote Sensing, Spatial Science

Recent studies suggest that water hyacinths play an important role in the transport of macroplastics in freshwater ecosystems. Forming large patches of several meters at the water surface, water hyacinths tend to entrain and aggregate large amounts of floating debris, including plastic items. Research on this topic is still novel and few studies have quantified the role of the water hyacinths in [...]

Optimizing Crop Cut Collection for Determining Field-Scale Yields in an Insurance Context

Ritvik Sahajpal, Inbal Becker-Reshef, Sylvain Coutu

Published: 2020-11-10
Subjects: Geographic Information Sciences, Geography, Other Engineering, Remote Sensing, Spatial Science

Accurately determining crop yields at field-scale can help farmers estimate their net profit, enable insurance companies to ascertain payouts, and when aggregated at regional and national scales, crop yield estimates are critical in ensuring food security. Over the last few decades, crop cuts have been widely used to estimate field-scale crop yields. Crop cuts, while cost prohibitive, are the [...]

Using Machine-Learning Models for Field-Scale Crop Yield and Condition Modeling in Argentina

Ritvik Sahajpal, Lucas Fontana, Pedro Lafluf, et al.

Published: 2020-11-09
Subjects: Environmental Studies, Geographic Information Sciences, Remote Sensing, Spatial Science

Accurately determining crop growth progress and crop yields at field-scale can help farmers estimate their net profit, enable insurance compa-nies to ascertain payouts, and help in ensuring food security. At field scales, the troika of management, soil and weather combine to impact crop growth pro-gress, and this progress can be monitored in-season using satellite data. Here, we use satellite [...]

Mapping Research Topics at Multiple Levels of Detail

Sara Lafia, Werner Kuhn, Kelly Caylor

Published: 2020-07-12
Subjects: Geography, Physical Sciences and Mathematics, Social and Behavioral Sciences, Spatial Science

Institutional reviews typically rely on scientometrics, like the h-index and impact factors of their participants, to assess research productivity. Productivity is not the only review criterion however, and scientometrics can be difficult to generate and compare in multidisciplinary settings. “Distant reading” methods from the Digital Humanities can complement the current quantitative evaluation [...]

Finding karstic caves and rockshelters in the Inner Asian mountain corridor using predictive modelling and field survey

Patrick Cuthbertson, Tobias Ullman, Christian Büdel, et al.

Subjects: Geographic Information Sciences, Geography, Physical and Environmental Geography, Social and Behavioral Sciences, Spatial Science

The area of the Inner Asian Mountain Corridor (IAMC) follows the foothills and piedmont zones around the northern limits of Asia’s interior mountains, connecting two important areas for human evolution: the Fergana valley and the Siberian Altai. Prior research has suggested the IAMC may have provided an area of connected refugia from harsh climates during the Pleistocene. To date, this region [...]

A framework to quantify the human footprint in Africa using supply and demand of net primary production

Subjects: Environmental Indicators and Impact Assessment, Environmental Sciences, Geography, Nature and Society Relations, Physical and Environmental Geography, Physical Sciences and Mathematics, Remote Sensing, Social and Behavioral Sciences, Spatial Science, Sustainability

The human-environment connection in the mostly rural drylands of Africa forms a complex, interlinked system that provides ecosystem services. This system is susceptible to climatic variability that impacts the supply of its products, and high population growth, which impacts the demand for these products. When plants remove carbon dioxide from the atmosphere through the process of photosynthesis, [...]

Subjects: Environmental Studies, Geography, Meteorology, Oceanography and Atmospheric Sciences and Meteorology, Physical Sciences and Mathematics, Social and Behavioral Sciences, Spatial Science

Concerns over climate change have led governments around the world to establish a range of renewable, low-carbon energy goals. Plans for meeting these targets vary widely in their ambition, specificity, and time horizons. Wind and solar electricity generation will feature prominently in future energy systems that meet these renewable, low-carbon energy goals. Implementing large-scale wind and [...]

Open science practices such as publishing data and code are transforming water science by enabling synthesis and enhancing reproducibility. However, as research increasingly bridges the physical and social science domains (e.g., socio-hydrology), there is the potential for well-meaning researchers to unintentionally violate the privacy and security of individuals or communities by sharing [...]
