Smart Sensor‐Integrated Lysimeter System for Affordable on‐Farm Crop Water Monitoring and Irrigation Management

Irrigation and Drainage, EarlyView.
ABSTRACT Accurate monitoring of crop water use is critical for precision irrigation, yet conventional lysimeter systems remain too costly and complex for widespread adoption. This study presents the development and field validation of a low‐cost, information and communication technology (ICT)‐enabled weighing lysimeter system that integrates load cells,

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.

Multi‐Country‐Multi‐City Characterisation of Heat Stress and Exposure in Africa

International Journal of Climatology, EarlyView.
This study provides the first continent‐wide, grid‐specific assessment of heat stress trends in Africa, revealing a sharp rise in multi‐scale extreme heat episodes and shifting population exposure. Findings highlight urgent implications for urban planning and climate adaptation.

On the Change of Plant Canopy Height with Wind Velocity

Journal of Agricultural Meteorology, 1969
A following relation between roughness lenghth (Z0) and zero-plane displacement (d) in the wind profile of very rough surfaces has been deduced recently (TAKEDA, 1966):lnH-d/Z0=k2/αH-d/H (1)where k=0.4 (von Karuman's constant), α=0.087 and H denotes the roughness height.

Soil Loosening of Compacted Urban Tree Sites Using a Pneumatic Lance Injector: Quantifying Treatment Success Through Tree Morphology and Soil Structure Parameters via Terrestrial Laser Scanning

Journal of Plant Nutrition and Soil Science, EarlyView.
ABSTRACT Background Urban trees provide essential ecosystem services, but their growth and longevity are often limited by soil compaction. Although pneumatic lance injection (PLI) is increasingly promoted as a minimally invasive and efficient soil loosening technique, but robust scientific evidence for its long‐term effectiveness remains limited.

Rice panicle temperature and crop microclimate in stressful thermal environments: toward a model of spikelet sterility [PDF]

, 2011
Rice inflorescences are sensitive to chilling and heat, resulting in spikelet sterility. It is not the air temperature itself, however, that causes the stress but the temperature of the sensitive tissues during specific developmental stages.

Insights into Red Deer Ecology during the Late Epigravettian: New isotopic evidence from Riparo Tagliente (Italian Prealps)

Journal of Quaternary Science, EarlyView.
Abstract The transition from the Last Glacial Maximum to the Late Glacial marked a shift from the cold conditions of Greenland Stadial‐2 (GS‐2) to the warmer phases of Greenland Interstadial‐1 (GI‐1), enabling the reoccupation of Alpine regions by Late Palaeolithic hunter‐gatherers.
