Spatial Insights into Drought Severity: Multi-Index Assessment in Małopolska, Poland, via Satellite Observations

Remote Sensing
This study focuses on the assessment of drought severity, employing a comparative analysis between the normalized multi-band drought index (NMDI; calculated using Sentinel-2 imagery) and the combined drought indicator (CDI). The research aims to pinpoint

Global Runoff Signatures Changes and Their Response to Atmospheric Environment, GRACE Water Storage, and Dams

Remote Sensing, 2021
Runoff signatures (RS), a special set of runoff indexes reflecting the hydrological process, have an important influence on many fields of both human and natural systems by flooding, drought, and available water resources.

The Spatial Coherence of European Droughts – Final Report [PDF]

, 2009
Drought can cause serious problems across much of Europe. Many droughts are localised and short, but others are widespread and cause environmental and social effects that cross international boundaries.

Principles for Rigorous Design and Application of Synthetic Microbial Communities

Advanced Science, EarlyView.
SynComs are artificially designed to enable inter‐species metabolic interactions, metabolic division of labor, and ecological interactions that can elicit phenotypes like colonization stability and environmental adaptation. This systematic review explores the processes used to construct SynComs, the assessment of the mechanisms of metabolic interaction

Proposing a new integration system: Tolerance Merged Collocation comparative to Modified and Scaled Triple Collocation and weighting scheme to integrate four indices

Geomatics, Natural Hazards & Risk
The absence of a global standard for drought assessment has led to inconsistencies in observational methods. This study explores recent advancements in merging techniques to enhance drought monitoring, develop more reliable indices, and introduce a ...

Satellite-Based Operational Real-Time Drought Monitoring in the Transboundary Lancang–Mekong River Basin

Remote Sensing, 2020
Existing gauging networks are sparse and not readily available in real-time over the transboundary Lancang−Mekong River (LMR) basin, making it difficult to accurately identify drought.

Water‐Efficient Smart Drip Irrigation Enabled by a Low‐Power and High‐Efficiency Flexible Electromagnetic Actuator

Advanced Science, EarlyView.
Water scarcity poses a critical threat to global food security. A low‐power, flexible electromagnetic actuator is presented for smart drip irrigation systems. The device achieves precise, wide‐range flow modulation (0.05–5.8 mL/min) in response to real‐time plant demands, reducing water consumption compared to conventional flood irrigation.

Agricultural Drought Monitoring: A Comparative Review of Conventional and Satellite-Based Indices

Atmosphere
Drought is a natural hazard that causes significant economic and human losses by creating a persistent lack of precipitation that impacts agriculture and hydrology. It has various characteristics, such as delayed effects and variability across dimensions
