Robust optimisation of urban drought security for an uncertain climate [PDF]

, 2013
Recent experience with drought and a shifting climate has highlighted the vulnerability of urban water supplies to “running out of water” in Perth, south-east Queensland, Sydney, Melbourne and Adelaide and has triggered major investment in water source ...

Adapting to Water Scarcity in Mediterranean Greenhouse Agriculture: Insights From Digital Irrigation and Regulated Water Governance in Southeastern Spain

Corporate Social Responsibility and Environmental Management, EarlyView.
ABSTRACT Climate‐driven water scarcity is compounding adaptation pressures on Mediterranean greenhouse farming, particularly for small and micro agricultural firms governed by regulated water‐governance systems. This paper analyses differentiated adaptation profiles in Almería (Spain) based on an analysis of farm structure, digital irrigation adoption,

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

Delayed rainfall diminishes the positive response of soil respiration to warming

Grassland Research, EarlyView.
Warming stimulates soil respiration and its components, while delayed rainfall suppresses them. Crucially, delayed rainfall diminishes or even reverses the positive response of soil respiration to warming by intensifying the drought stress, and autotrophic respiration is more vulnerable than heterotrophic respiration under this interaction.

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

Grassland 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 ...

Quantifying the impact of large hydropower station regulation and storage operations on downstream river and lake hydrological drought risks

Hydrology Research
The operation of the Three Gorges Reservoir has significantly altered the hydrological regime of the Yangtze River, advancing dry seasons and lowering water levels downstream, thereby exacerbating hydrological drought risks. However, its specific role in
