Estimating Soil Compaction Risk at Regional Scales Using Meteorological Data and Soil Spectroscopy

Land Degradation &Development, EarlyView.
ABSTRACT Soil compaction is a significant form of soil degradation in Europe, reducing agricultural productivity, limiting carbon sequestration and increasing greenhouse gases emissions. In response, the forthcoming European Union Soil Monitoring and Resilience Law requires spatial assessment of topsoil and subsoil compaction risk at district, that is,

A simple index for assessing cumulative human impacts on mountain lakes

Limnology and Oceanography: Methods, EarlyView.
Abstract Mountain lakes are highly sensitive ecosystems and effective sentinels of environmental change, yet the exposure and magnitude of the human footprint remain poorly quantified. In this study, we develop a simple and non‐invasive abiotic index to assess cumulative pressures on mountain lakes. The proposed index integrates eight variables grouped

Populism and policy capacity: Evidence from an opposition municipality in Istanbul

Public Administration and Development, EarlyView.
Abstract Despite achievements in its conceptual rigor, policy capacity still represents a relatively depoliticized concept that fails to sufficiently consider the ways in which politics plays a role in its creation, mobilization, or decay. This article seeks to contribute to this debate by investigating the impact of populism on policy capacity, the ...
