Evaluation of hydrological flow regime alteration and its ecological consequences in the Gilgel Abay River Basin, Ethiopia

This study evaluates the Gilgel Abay River Basin in Ethiopia using 42 years of hydrological data and the Indicators of Hydrologic Alteration model, revealing a significant shift toward low-flow conditions and the cessation of major flood events since the mid-1990s, which has led to substantial ecological degradation and underscores the urgent need for sustainable flow management.

Ecological niche modeling reveals severe historical range contraction and contemporary refugia for the narrow endemic Arctium pallidivirens in Central Asia

By integrating field surveys and historical records with ensemble species distribution modeling, this study reveals that the narrow endemic *Arctium pallidivirens* in Central Asia has undergone severe historical range contraction, with its current distribution confined to a small fraction of its potential habitat within climatically buffered refugia.

From forecast skill to planning value: multi-horizon data-driven hydrological forecasting for sustainable management of the Jucar River Basin District

This study presents a data-driven multi-horizon forecasting pipeline for the Jucar River Basin that successfully generates monthly predictions of aquifer levels, reservoir storage, and river discharge up to 48 months ahead by separating endogenous memory from exogenous climate and demand drivers, demonstrating high skill for groundwater and reservoirs while identifying systematic bias as the primary limitation for long-range river forecasts under various future scenarios.

Profound changes in tropical North African wetland extent and their socio-ecological consequences

Using high-resolution satellite data from 2014 to 2023, this study reveals an 86% surge in wetland extent across the Sahel and East Africa driven by recent climatic shifts, a transformation that has permanently altered regional flood baselines and poses urgent socio-ecological challenges to major cities, refugee camps, and agricultural systems.
