Soil erosion assessment tools from point to regional scales—the role of geomorphologists in land management research and implementation

Increasing concern about the effects of agriculture on the environment has drawn attention to the inadequate scientific base on which many policy decisions are made. Decisions on how soil should best be protected from erosion demand knowledge of the risk of erosion and of the relative effectiveness of different conservation measures. Process-based erosion models are designed to provide this information. This paper outlines one such model, the European Soil Erosion Model (EUROSEM), which is being developed jointly by scientists from ten European countries. The model incorporates some of the best process-based erosion research being carried out in Europe and, compared with other similar models, contains novel features in the way rill–interrill interactions and the role of vegetation are described. Tests of the model in the UK show that it performs rationally and gives reasonable predictions of storm soil loss and runoff. Some examples of how the model might be used to evaluate conservation measures are provided.

Injury Assessment

It has been widely accepted that the assessment of balance after concussion plays a large role in determining deficit. Qualitative balance assessments have been an established piece of the post-injury assessment as a clinical behavioral marker of concussion for many years. Recently more specific guidelines outlining the role of balance evaluation in concussion identification and management have been developed as part of concussion management tools. As part of the ongoing development of concussions protocols, quantitative assessment of balance function following concussion has also been identified to have an important role. Frequently imbalance and dizziness reported following concussion is assumed to be associated with post-concussion syndrome (PCS). While imbalance and dizziness are common complaints in PCS, they can also be a sign of additional underlying pathology. In cases of specific dizziness symptoms or limited balance recovery beyond the initial post-concussive period, a quantitative vestibular assessment may also be needed. Electronystagmography and videonystagmography (ENG/VNG), rotary chair testing (RCT), and vestibular evoked myogenic potentials (VEMPs) have all been identified as valid assessment tools for vestibular dysfunction following traumatic brain injury (TBI). The assessment of balance and dizziness following sports-related concussions is an integral piece of the puzzle for removal from play, assessment of severity, and management.

Soil Erosion Assessment

Analysis of two small semi-mountainous catchments in central Evia island, Greece, highlights the advantages of Unmanned Aerial Vehicle (UAV) and Terrestrial Laser Scanning (TLS) based change detection methods. We use point clouds derived by both methods in two sites (S1 & S2), to analyse the effects of a recent wildfire on soil erosion. Results indicate that topsoil’s movements in the order of a few centimetres, occurring within a few months, can be estimated. Erosion at S2 is precisely delineated by both methods, yielding a mean value of 1.5 cm within four months. At S1, UAV-derived point clouds’ comparison quantifies annual soil erosion more accurately, showing a maximum annual erosion rate of 48 cm. UAV-derived point clouds appear to be more accurate for channel erosion display and measurement, while the slope wash is more precisely estimated using TLS. Analysis of Point Cloud time series is a reliable and fast process for soil erosion assessment, especially in rapidly changing environments with difficult access for direct measurement methods. This study will contribute to proper georesource management by defining the best-suited methodology for soil erosion assessment after a wildfire in Mediterranean environments.

The One

This paper is built on the following research questions: (i) What are the direct/indirect relationships between Sustainable Development Goal 11 (SDG11) and sustainability protocols? (ii) Could the sustainability protocols constitute a solution towards the achievement of SDG11? We underline that, on the one hand, the SDGs are guidelines to support the development of sustainable policies and thus address all elements that may affect them, and on the other hand, sustainability protocols are assessment tools to promote sustainability-conscious design while remaining focused on the built environment. In the Italian regulatory context, the paper highlights how this difference in terms of focus and scale means that they only overlap and mutually reinforce each other with regard to certain aspects, more related to energy and air pollution issues and less to the social aspects of sustainability. Even if there is not always a direct relationship between the evaluation criteria of the protocols and the indicators of SDG11, it is possible to conclude that the sustainability protocols can facilitate the achievement of the SDG11 targets, acting as a key for the implementation of sustainable cities and helping in structuring the process leading to sustainability in a broader framework.

Soil Particles

Excessive amounts of atmospheric precipitation can cause intense soil erosion, landslides, inundation and floods. Torrential rains have the force to displace and transport soil particles, so the risk of soil erosion becomes real, as many times as atmospheric precipitations have a devastating character. In this context, it is extremely useful to know the particularities of the torrential rains in the current regional climate. At this stage, the Fournier (IF) pluvial aggression index is becoming more and more prevalent. This paper is dedicated to the use of this index with the pluviometric Excess Danger index (IPP) developed at regional level. The results obtained show close concordance between these indices for temporal estimations. Spatial analyzes highlight the role of slopes' orientation in distributing the pluviometric Excess Danger index and slopes' degree of inclination in the case of the Fournier pluvial aggression index. The results obtained are useful in the efficient use of agricultural land and in the elaboration of measures for the improvement of degraded soils.
