Beyond Prediction: Data, Baselines, Explanation, and Causation in Machine Learning for Food Insecurity

Food Safety and Health, EarlyView.
The gains from machine learning in nowcasting and forecasting food insecurity are still small and limited and cannot be observed in all countries. This review summarizes the public resources for data, corrects common misconceptions about model requirements, and establishes baseline requirements, explanations, causal inference, and equity in operational

Estimating Riparian and Agricultural Actual Evapotranspiration by Reference Evapotranspiration and MODIS Enhanced Vegetation Index [PDF]

Remote Sensing, 2013
Dryland river basins frequently support both irrigated agriculture and riparian vegetation and remote sensing methods are needed to monitor water use by both crops and natural vegetation in irrigation districts. We developed an algorithm for estimating actual evapotranspiration (ETa) based on the Enhanced Vegetation Index (EVI) from the Moderate ...

Spatial Patterns of Seed Plants and Their Conservation Priorities in Jiangxi Province, China 中国江西省种子植物的空间格局及其保护优先区

Integrative Conservation, EarlyView.
We comprehensively evaluated the seed plant diversity of Jiangxi province to address the regional biodiversity conservation of Asian subtropical evergreen broad‐leaved forests (EBLFs). Higher species diversity of seed plants was observed in eastern, southern, and western Jiangxi, with elevation and precipitation as mainly environmental factors.

A Semiempirical Method to Estimate Actual Evapotranspiration in Mediterranean Environments [PDF]

Advances in Meteorology, 2018
Actual evapotranspiration (ETA) is a major term of site water balance whose knowledge is essential for numerous purposes. The classical ETA estimation approach based on the use of multitemporal crop coefficients (Kc) cannot be applied in water-limited environments without proper correction. Such correction can be theoretically obtained by means of soil

The investigation of actual evapotranspiration with the use of thermography

Proceedings of the 1998 International Conference on Quantitative InfraRed Thermography, 1998
In the study actual evapotranspiration was calculated from the energy balance equation in which the radiation temperature of plant cover is a component of sensible heat flux expressing the transport of heat energy from evaporating surface to the atmosphere.

Turning Water to Wine: An Analysis of Texas Wine Industry Water Management

Irrigation and Drainage, EarlyView.
ABSTRACT The Texas wine industry is expanding in scale and reputation during a period when sustainability concerns are increasingly visible and valuable to grape growers and wine producers in Texas. Most vineyard hectarage in Texas is in the High Plains and Hill Country American Viticultural Areas (AVAs), which rely on regional aquifers for water. With

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,

Analysis of Changes in Reference Evapotranspiration, Pan Evaporation, and Actual Evapotranspiration and Their Influencing Factors in the North China Plain During 1998–2005

Earth and Space Science, 2019
Evapotranspiration (ET) plays an important role in both energy and water balances. Determining changes in the different types of ET and their influencing factors under climate change is crucial to fully understand the mechanisms controlling ET and ...
