Future changes of global potential evapotranspiration simulated from CMIP5 to CMIP6 models

open access: yes, 2020
This research evaluated the ability of different coupled climate models to simulate the historical variability of potential evapotranspiration (PET) for the time period 1979–2017 in phases 5 and 6 of the Coupled Model Intercomparison Project (CMIP5 and ...

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

open access: yesFood 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

Estimation of Environmental Quality Based on Ecometric Climatic Indicators (on the Example of the Republic of Moldova)

open access: yesPresent Environment and Sustainable Development, 2018
Aridity in new climatic conditions requires indexes which could adequately explain this process. All the more so, the quantities of atmospheric precipitations also continue to increase on the background of the temperatures increase in the conditions of ...

Assessing the sensitivity of standardized precipitation evapotranspiration index to three potential evapotranspiration models in Nigeria

open access: yes, 2020
Drought indices are very essential in monitoring and planning for drought occurrences. Though many indices have been established over the years, it is expected that proper investigation should be done using these indices to know the ones that can better ...

Green water, wetlands, and atmospheric moisture recycling ‐ An emerging new paradigm for grassland science

open access: yesGrassland Research, EarlyView.
The importance of green water in water resource management. Conceptual classification of terrestrial water components highlighting the central role of green water in land‐atmosphere interactions. This schematic distinguishes green water (soil moisture available for plant uptake and evapotranspiration) from blue water (surface water, groundwater, and ...
