Optimizing Flood Hazard Zonation and Planning Landscape‐Based Mitigation Measures in Gimba Sub Watersheds, Northeastern Ethiopia: A Comprehensive Approach

open access: yesJournal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT Flooding remains one of the most critical natural hazards threatening livelihoods, infrastructure, and ecological systems in Ethiopia's highland landscapes. This study presents a rigorously integrated, multi‐criteria flood risk assessment that combines the Analytical Hierarchy Process (AHP) with GIS‐based spatial modeling to delineate ...

Extreme‐weather risk and the cross‐section of stock returns

open access: yesJournal of Risk and Insurance, Volume 93, Issue 1, Page 163-198, March 2026.
Abstract We document an extreme‐weather risk premium in the cross‐section of stock returns. Between 1995 and 2019, stocks of domestic U.S. firms with the most negative sensitivity to aggregate storm losses earned an annual excess‐return spread of more than 6 percentage points relative to those with the most positive sensitivity, a difference not ...

Of cells and cities: a comparative Econometric and Cellular Automata approach to Urban Growth Modeling [PDF]

open access: yes
This paper presents a comparative assessment of two distinct urban growth modeling approaches. The first urban model uses a traditional Cellular Automata methodology, based on Markov transition chains to prospect probabilities of future urban change ...

Urbanization and Spatial Aggregation Impair Multifunctionality in Urban Vacant Lots

open access: yesEcology and Evolution, Volume 16, Issue 2, February 2026.
This study provides the first assessment of biodiversity and ecosystem multifunctionality in urban vacant lots. Although urbanization and spatial aggregation of vacant lots impaired multifunctionality, soil moisture improved it. ABSTRACT Urban shrinkage, driven by population decline rather than expansion, is an emerging concern in many developed ...

Lock-in effects of road expansion on CO2 emissions : results from a core-periphery model of Beijing [PDF]

open access: yes
In the urban planning literature, it is frequently explicitly asserted or strongly implied that ongoing urban sprawl and decentralization can lead to development patterns that are unsustainable in the long run.

Urban landscapes as ecological filters: Insights from a Neotropical bird assemblage

open access: yesEcology, Volume 107, Issue 2, February 2026.
Abstract To contribute to our growing understanding of the urban ecological filtering process in highly biodiverse regions, we conducted a study on bird species assemblages across the landscape of Medellín and its surrounding areas in the Colombian Andes.

URBAN SPRAWL, PATTERN AND MEASUREMENT IN LOKOJA, NIGERIA [PDF]

open access: yes
Lokoja have been experiencing a large influx of population from its surrounding regions, which had led to rapid growth and expansion that had left profound changes on the landscape in terms of land use and land cover.

Colours of urban selection: carotenoid‐based signals reveal divergent urban/rural evolutionary trajectories in two closely related passerines

open access: yesOikos, Volume 2026, Issue 2, February 2026.
Urbanisation is a major driver of environmental change, reshaping ecological and evolutionary processes. Urban‐driven phenotypic differences are increasingly documented, but the underlying role of selection is still understudied. One pattern is the consistent reduction of carotenoid‐based plumage pigmentation in city birds.
