Predictive Ecosystem Health Assessment Under Land‐Use and Vegetation Dynamics in a Semi‐Arid Rift Valley Basin, Ethiopia

Land Degradation &Development, EarlyView.
ABSTRACT Land degradation driven by rapid land‐use and climate‐driven vegetation dynamics increasingly threatens ecosystem stability in semi‐arid wetland basins, yet predictive ecosystem health assessments remain limited in Sub‐Saharan Africa. This study evaluates historical dynamics and future trajectories of ecosystem health in the Ziway‐Shalla Sub ...

The Importance of the Normalized Difference Vegetation Index (NDVI) and the Use of the ArcGIS to create NDVI Maps

مجلة العلوم والدراسات الإنسانية - كلية الآداب والعلوم – المرج
This paper studies the Normalized Difference Vegetation Index (NDVI); the creation of the NDVI maps, how these maps are work, and how to create them using ArcMap. These maps sort the vegetation into low and high up to the NDVI values (±0.1). It measures greenness, vegetation health, predicts agricultural productivity, and map desertification; it is an ...

Characterising fine‐scale habitat associations for range expanding species with limited data: a case study on the West Nile Virus vector, Culex modestus

Oikos, EarlyView.
The ecological and epidemiological consequences of species expanding into new areas are growing concomitantly with climate change. Those aiming to monitor species expanding in range must make optimal use of finite resources to deliver effective surveillance capable of detecting new incursions and range expansions.

Green pathways to mental health: Relationships between treescapes and well‐being and distress

People and Nature, EarlyView.
Abstract We aimed to evaluate the mental health benefits and possible mechanisms of objective and subjective treescape exposures whilst also accounting for relationships with residential area greenspace in general. Independent variables were objective measures of residential neighbourhood tree cover density and woody linear features, and a subjective ...

Made in the shade: Leaf responses of native wildflowers to single‐axis photovoltaic solar energy

PLANTS, PEOPLE, PLANET, EarlyView.
As solar energy expands globally, balancing renewable power generation with biodiversity and ecosystem health has become an urgent challenge. This study investigated how native wildflowers respond at leaf level to the unique microclimates created by rotating solar panels in California's Central Valley.

Band-Based Best Model Selection for Topographic Normalization of Normalized Difference Vegetation Index Map

IEEE Access, 2020
Topographic effect in remote sensing images is severe in high mountainous areas. Efficiently to reduce the effects, several topographic normalization models have been proposed. Since the performance of the models is largely dependent on the spectral band

Bridging Human and Plant Adaptations for Climate Resilience

PLANTS, PEOPLE, PLANET, EarlyView.
Climate change is transforming agriculture through both gradual shifts and increasingly unpredictable extremes, challenging farmers' ability to protect crops and livelihoods. This study brings together farmer experiences and plant adaptation strategies to explore how people and plants respond to similar climate pressures.

Using Data Mining Techniques to Forecast the Normalized Difference Vegetation Index (NDVI) in Table Grape

Proceedings of the 8th International Conference on Operations Research and Enterprise Systems, 2019
The Normalized Difference Vegetation Index (NDVI) is a simple indicator that quantifies aerial biomass in fruit crops, which is correlated with the fruit yield and quality produced by an orchard. Therefore, knowing the NDVI values would allow predicting productive parameters above mentioned, which in turn would help planning operational activities such

Effects of timed LED regimes on tomato plant traits, performance of two‐spotted spider mites, and predatory mites (Phytoseiulus persimilis)

Pest Management Science, Volume 81, Issue 4, Page 2300-2311, April 2025.
Light‐emitting diode (LED)‐based treatments for enhancing crop production and pest management have primarily focused on continuous treatments. This study, using Tetranychus urticae and Phytoseiulus persimilis, demonstrates that the timing of LED supplementation is crucial for designing integrated pest management strategies that improve both plant ...

UV-NDVI for real-time crop health monitoring in vertical farms

Smart Agricultural Technology
This study aims to develop a plant health monitoring system suitable for vertical farms. It began by creating a multispectral LED with UVA and NIR light sources and an IoT device capable of controlling the LED spectrum. The IoT device integrates a camera
