Atmospheric teleconnection mechanisms of extratropical North Atlantic SST influence on Sahel rainfall [PDF]

, 2014
Extratropical North Atlantic cooling has been tied to droughts over the Sahel in both paleoclimate observations and modeling studies. This study, which uses an atmospheric general circulation model (GCM) coupled to a slab ocean model that simulates this ...

Assessment of soil erosion by Universal Soil Loss Equation model based on Geographic Information System data: a case study of the Mafragh watershed, north-eastern Algeria

Scientific African, 2023
: Soil resources in Algeria are limited by physical surface area, geogenic, and anthropogenic degradation. Given the importance of food production, soil resource management is an essential part of Algeria's long-term agricultural development. Furthermore,

Severity of Compound Precipitation and Temperature Extreme Events Over Africa at 1.5°C and 2°C Global Warming Levels

International Journal of Climatology, EarlyView.
Results indicate that, an increase in global warming level from 1.5°C to 2°C is likely to induce on the one hand a 3‐fold increase in the frequency of occurrence of dry and warm compound events, and on the other hand a 2‐fold increase in their duration, over West, Central, South‐West, and South‐East Africa, intensifying droughts through reduced ...

Synchronisation of Extreme Precipitation and Sea Surface Temperature Events in the Northern Hemisphere: A Complex Network Approach

International Journal of Climatology, EarlyView.
Using complex network theory and event synchronisation, we find distinct spatiotemporal structures of extreme precipitation and sea surface temperature events across the Northern Hemisphere. Our results show strong local and long‐range connectivity in terrestrial extremes, driven by atmospheric dynamics, contrasting with more localised marine extremes ...

Comparing the Last Interglacial (MIS 5e) with the present interglacial period (MIS 1) using a multidimensional functional diversity analysis: The marine molluscs from Santa Maria Island (Azores Archipelago, central Atlantic) as a case study

Journal of Quaternary Science, EarlyView.
ABSTRACT Marine fossil records hold outstanding importance for ecological, evolutionary and biogeographical studies. Santa Maria Island in the Azores Archipelago (central Atlantic) features a remarkable marine fossil record spanning from the Pliocene to recent times.

Gender and Land Degradation Neutrality (LDN): Evaluating Nigeria's Legislative Framework for Achieving Gender‐Equitable LDN Outcomes

Land Degradation &Development, EarlyView.
ABSTRACT Legislative frameworks that support gender equality are crucial for addressing structural inequalities, protecting women's rights, and achieving gender‐equitable land degradation neutrality (LDN) outcomes. This study examines the extent to which national‐level policies and legislation governing LDN and related sectors incorporate gender ...
