Optimizing Agricultural Drought Monitoring in East Africa: Evaluating Integrated Soil Moisture and Vegetation Health Index (SM-VHI)

Remote Sensing
This study presents a comprehensive analysis of the integrated Soil Moisture–Vegetation Health Index (SM-VHI) as a robust tool for drought detection and agricultural monitoring across East Africa using data from 2000 to 2020. A sensitivity analysis within the SM-VHI algorithm identified an optimal parameter weighting (α = 0.5), which improved detection

Soil Moisture Prediction in Pavement Layers Using LSTM Neural Networks

Geotechnical and Geological Engineering
Moisture content in geomaterials critically impacts road construction. Optimising the Optimum Moisture Content (OMC) during compaction reduces energy usage and construction costs, but materials often require adjustments upon delivery to reach OMC.

Is quinoa‐farming sustainable in marginal environments? Social, economical and environmental aspects

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Quinoa (Chenopodium quinoa Willd.) is an Andean grain crop introduced as a novel crop to many parts of the world in recent years. Recognized for nutritious seeds and high abiotic stress tolerance, it has been promoted as an element of climate‐resilient agriculture, particularly in marginal environments.

Spatial Downscaling of Satellite-Based Soil Moisture Products Using Machine Learning Techniques: A Review

Remote Sensing
Soil moisture (SM) is a key variable driving hydrologic, climatic, and ecological processes. Although it is highly variable, both spatially and temporally, there is limited data availability to inform about SM conditions at adequate spatial and temporal ...

The effects of soil compaction on wheat seedling root growth are specific to soil texture and soil moisture status [PDF]

Soil structure is a crucial soil physical property that determines a soil's ability to support the growth and development of plants. Soil compaction modifies soil structure by reducing pore space between soil particles thereby leading to a denser soil ...

Physical and Chemical Characterization of Soil in Urban Solid Waste Disposal Area

Land Degradation &Development, EarlyView.
ABSTRACT Waste generation and subsequent disposal in adequate sites still have limitations in some Brazilian municipalities. Therefore, environmental monitoring of these areas is extremely important, as it helps to preserve the environment. The purpose of this study is to analyze the chemical and physical parameters of soil in a landfill area. For this,

Hydrologic validation of remote sensing soil moisture product

, 2013
Soil moisture represents a fundamental quantity to understand the interaction between the land surface and the atmosphere. As widely-known, it can be estimated through modelling approaches, in situ measurements and satellite sensors.

Can current moisture responses predict soil CO2 efflux under altered precipitation regimes?: a synthesis of manipulation experiments [PDF]

, 2014
As a key component of the carbon cycle, soil CO2 efflux (SCE) is being increasingly studied to improve our mechanistic understanding of this important carbon flux. Predicting ecosystem responses to climate change often depends on extrapolation of current

Cropland Suitability–Use Mismatches and Differentiated Zoning Regulation in the North China Plain: Implications for Spatially Optimised and Sustainable Land Use

Land Degradation &Development, EarlyView.
ABSTRACT Cropland distribution is often shaped by historical cultivation patterns rather than natural suitability, leading to mismatches between actual land use and agricultural production potential. However, their extent and spatial characteristics remain insufficiently understood in the North China Plain, one of China's most important grain‐producing
