Temperature and heat‐load exposure effects on preterm births: Insights from a population‐based study using distributed lag non‐linear models

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Objective Preterm birth presents a substantial health, psychological, and economic burden worldwide. Environmental factors, including temperature fluctuations, are known to influence the risk of preterm birth. This study aimed to investigate the association between high temperatures and heat load and preterm births. Methods Using a time‐series

A Dynamic Landsat Derived Normalized Difference Vegetation Index (NDVI) Product for the Conterminous United States [PDF]

Remote Sensing, 2017
Satellite derived vegetation indices (VIs) are broadly used in ecological research, ecosystem modeling, and land surface monitoring. The Normalized Difference Vegetation Index (NDVI), perhaps the most utilized VI, has countless applications across ecology, forestry, agriculture, wildlife, biodiversity, and other disciplines.

Drought Risk in Mango and Avocado Orchards: Insights Into Plant Water Relations and Irrigation‐Related Agronomic Solutions

Irrigation and Drainage, EarlyView.
ABSTRACT Climate change is making water availability more uncertain, with growing consequences for the productivity and long‐term sustainability of tropical and subtropical fruit orchards. Mangifera indica L. and Persea americana Mill. both require large amounts of water to sustain growth and productivity.

Evapotranspiration Estimation and Irrigation Performance Assessment Using Remote Sensing: A Case Study of the Ergani Dam Irrigation System (Turkey)

Irrigation and Drainage, EarlyView.
ABSTRACT Efficient water resource management is critical for sustainable agriculture, with evapotranspiration (ET) serving as a key parameter. Remote sensing (RS) techniques offer cost‐effective approaches for ET estimation and irrigation performance assessment in extensive agricultural systems.

Modeling land use dynamics and land surface temperature using GEE and CA-ANN: a case study of Pakistan's freshwater basins

Geocarto International
This study analyses land use/land cover (LULC) changes using observations from 2000, 2010 and 2020, and projects future dynamics up to 2070. Land surface temperature (LST) and spectral indices, including the normalized difference vegetation index (NDVI),

Projections of Meteorological Drought and Potential Evapotranspiration Using the RegCM4 Over Northeastern Iran

International Journal of Climatology, EarlyView.
We downscale CanESM2 with the Regional Climate Model version 4 (20 km) and evaluate against 15 stations to derive monthly PET (Hargreaves–Samani) and SPEI for northeastern Iran (1990–2009, 2040–2059, 2080–2099). Results show robust PET increases and a shift toward more negative monthly SPEI—especially April–September—indicating earlier onset and longer

Fire Recurrence and Normalized Difference Vegetation Index (NDVI) Dynamics in Brazilian Savanna [PDF]

Fire, 2018
Fire is one of the main modeling agents of savanna ecosystems, affecting their distribution, physiognomy and species diversity. Changes in the natural fire regime on savannas cause disturbances in the structural characteristics of vegetation. Theses disturbances can be effectively monitored by time series of remote sensing data in different terrestrial

Wheat Wild Relatives and Modern Cultivars Differ for Salt Resistance in Terms of Morpho‐Physiological Traits

Journal of Plant Nutrition and Soil Science, EarlyView.
Wheat wild relatives are untapped genetic resources from salinity and drought hit areas. This study presents differential comparative morphophysiological responses of these species and modern wheat cultivars under saline conditions. Salt resistant species produce more shoot and root biomass under saline conditions through salt exclusion and/or tissue ...
