Cacao trees under different shade tree shelter: effects on water use

Environmental Science
It is argued that differences originate from stomatal control of transpiration in the monoculture and altered radiation conditions and a different degree of uncoupling of the VPD from the bulk atmosphere inside shaded stands and this did not result in significantly altered average daily cacao water use rates.

Environmental Science
The expansion of rubber cultivation in Southeast Asia raises concerns about the integrity of the hydrological cycle. From mainland Asia, high evapotranspiration from rubber plantations was reported.…
Water scarcity and oil palm expansion: social views and environmental processes

Environmental Science
For the purpose of characterizing spatial variability of soil hydraulic properties on a forested hillslope, five differing scaling methods were examined using the data set for 30 undisturbed forest…
Predicting Tree Sap Flux and Stomatal Conductance from Drone-Recorded Surface Temperatures in a Mixed Agroforestry System - A Machine Learning Approach
- Florian EllsäßerA. Röll D. Hölscher
- 12 December 2020
Environmental Science, Agricultural and Food Sciences
There is large potential in machine learning approaches for ecological applications such as predicting transpiration in sap flux and leaf stomatal conductance based on drone-recorded and meteorological data and compare these predictions with in-situ measured transpiration.

Examining the environmental drivers of Es on an intra-daily scale indicates an early, pre-noon maximum of Es rates (11 am) due to a very sensitive reaction of Es to increasing vapor pressure deficit in the morning, which results in pronounced hysteresis, particularly between Es and vapor pressure deficits.
