A robust multi-functional decision support system for widespread planning of nature-based solutions (NBSs) must incorporate components of social equity. NBS systems advance social well-being through enhanced levels of greenspace, which have been shown to improve physical health (e.g., heart disease, diabetes), mental health (e.g., post-traumatic stress disorder, depression), and socio-economics [...]

Flooding is one of the most frequent natural disasters, causing billions of dollars in damage and threatening vulnerable communities worldwide. Although the impact of flooding can never be diminished, minimizing future losses is possible by taking structural or non-structural mitigation actions. Mitigation applications are often costly practices. However, they can be more feasible for long-term [...]

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 [...]

Creating a climate changed future with the sea level rise interactive- fiction game ‘Lagos2199’

Story-based futures serve an important role in climate change scenario development. Stories are particularly useful in exploring sea level rise possibilities, since we know many coastal areas are specifically vulnerable to accelerating rises in sea level. This discrete change in coastline is different from most other climate change impacts, and offers a clear basis for scientifically-informed, [...]

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 field boundaries for smallholder-dominated croplands at national scales

Mapping the characteristics of Africa's smallholder-dominated croplands, including the sizes and numbers of fields, can provide critical insights into food security and a range of other socioeconomic and environmental concerns. However, accurately mapping these systems is difficult because there is 1) a spatial and temporal mismatch between satellite sensors and smallholder fields, and 2) a lack [...]

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

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, [...]

The UK needs an open data portal dedicated to coastal flood and erosion hazard risk and resilience

Eli Lazarus, Sofia Aldabet, Charlotte E L Thompson, et al.

Subjects: Geographic Information Sciences, Geomorphology, Natural Resources Management and Policy, Nature and Society Relations, Sustainability

In the UK, coastal flooding and erosion are two of the primary climate-related hazards to communities, businesses, and infrastructure. To better address the ramifications of those hazards, now and into the future, the UK needs to transform its scattered, fragmented coastal data resources into a systematic, integrated, quality-controlled, openly accessible data portal. Such a portal would support [...]

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

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 [...]

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 [...]
