Divergent responses of hysteresis loops and sediment sources to rainfall regimes in karst small watersheds of Southwest China: A multi-method integrated framework for classifying erosive rainfall patterns

Journal of Hydrology: Regional Studies
Study region: A typical karst small watershed in Southwest China. Study focus: Rainfall patterns regulate runoff–sediment dynamics, yet the mechanisms linking specific patterns to hydro-sedimentary regimes and sediment sources remain unclear.

Zoning of erosion potential of water accumulated in snow cover based on climatological data analysis

Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2009
Melting of snow in winter and early spring often causes soil erosion. The results of erosion studies show that the runoff generated in the cold period can cause more intensive erosion than in the warm half year.

Perceptions of Governance (Il)Legitimacy Mediate Climate Change Adaptation in the Lake Victoria Basin, Uganda

Environmental Policy and Governance, EarlyView.
ABSTRACT Governance is a well‐known dimension of adaptive capacity across various frameworks, however specific links between perceptions of governance (il)legitimacy and adaptive capacity remain relatively unexplored. In this study, we investigate connections between climate change adaptation and perceptions of governance (il)legitimacy using focus ...

Environmental Statecraft, Fragmented Authoritarianism, and Technocratic Governance: The Structure and Agency of China's Local Environmental Politics

Environmental Policy and Governance, EarlyView.
ABSTRACT Local environmental politics in China is often said to be dominated by state‐controlled modes of multi‐level governance. However, top‐down governance is embedded within and transformed by local politics, adding complexity to governance practices and environmental outcomes.

Assessing Policy‐Oriented Learning About Climate‐Related Forest Disturbances in Europe

Environmental Policy and Governance, EarlyView.
ABSTRACT European forests provide multiple ecosystem services but are increasingly under pressure from climate‐related disturbances such as droughts, storms and insect calamities. Forest policy is an important driver for the adaptation of forest management practices to climate change.

Time‐Variant Seismic Fragility of Reinforced Concrete Bridge Piers Considering Degradation Phenomena

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Aging and environmental exposure progressively deteriorate the physical and mechanical properties of construction materials, thereby affecting the safety and functionality of existing infrastructure. Corrosion of steel rebars in reinforced concrete structures is widely acknowledged as the most common and detrimental degradation phenomenon, as ...

Impact of Sahelian Climate Variables on Solar Photovoltaic Output

Energy Science &Engineering, EarlyView.
ABSTRACT Solar photovoltaic (PV) energy is a critical pathway for advancing the energy transition in the Sahel. However, PV module performance in this region is strongly constrained by extreme climatic conditions. This study investigates the effects of (1) wind speed, (2) relative humidity, (3) temperature, (4) dust deposition, and (5) solar irradiance

The Critical Role of Economies of Scale: A Techno‐Economic Assessment of Small‐ Versus Large‐Scale Biogas Upgrading in Rural Tanzania

Energy Science &Engineering, EarlyView.
Small‐scale biogas upgrading can improve methane quality but remains financially unattractive to individual rural households. Community‐scale implementation substantially lowers energy costs, demonstrating that economies of scale are critical to making purified biogas a viable clean‐cooking option in Tanzania.
