Hydrological drought insurance for irrigated agriculture in southern Spain

Agricultural Water Management, 2020
In Mediterranean-climate regions, irrigated agriculture is especially vulnerable to the risk of hydrological drought, and irrigators are particularly concerned about the negative effects of water supply failures. This paper proposes a new index-based drought insurance scheme to cover the risk of water supply failures in irrigated agriculture that ...

Trade‐offs among restored ecosystem functions are context‐dependent in Mediterranean‐type regions

Ecography, EarlyView.
Global biodiversity hotspots, including Mediterranean‐type ecosystems worldwide, are highly threatened by global change that alters biodiversity, ecosystem functions, and services. Some restoration activities enhance ecosystem functions by reintroducing plant species based on known relationships between plant traits and ecosystem processes.

A test of the abundant‐center hypothesis for stream fishes

Ecography, EarlyView.
The abundant‐center hypothesis (ACH) provides a conceptual model for predicting range‐wide distributions of species abundance, suggesting that abundance peaks in the center of the geographic range and declines towards range edges. Empirical studies testing the ACH and its subsequent derivations predominantly occurred in terrestrial systems and reported

Uncertainty in inventories for life cycle assessment: State‐of‐the‐art, challenges, and new technologies

Environmental Progress &Sustainable Energy, EarlyView.
Abstract Uncertainty is a critical factor that can hinder the quality and potential applications of life cycle assessment (LCA) results. A prominent source of uncertainty stems from the life cycle inventory (LCI) data. Various methodologies exist to estimate the uncertainty associated with LCI data, primarily based on the widely used structured ...

Spatial distribution of land type in regression models of pollutant loading [PDF]

, 2005
This paper proposes a method to improve landscape-pollution interaction regression models through the inclusion of a variable that describes the spatial distribution of a land type with respect to the pattern of runoff within a drainage catchment.
