Digitisation of herbarium specimens to the benefit of research: An African perspective focusing on South Africa and Western Indian Ocean Island states

PLANTS, PEOPLE, PLANET, Volume 8, Issue 4, Page 1042-1056, July 2026.
Botanical exploration, discovery and conservation rely heavily on access to herbarium collections. Recently, digital access to label information, including georeferenced locality data, and images of herbarium specimens available online have greatly increased usage of herbarium specimen data.

Soil Moisture Impact on Convective Initiation

Water Resources Research, Volume 62, Issue 7, July 2026.
Abstract The influence of soil moisture on convective storm initiation remains an open question, with previous studies showing conflicting results regarding whether storms preferentially form over wet or dry soils. Here, we analyze the soil moisture‐convection relationship using satellite observations across North America, Africa, and Australia from ...

Last of the JEDI's: “Coloured” Women's Active Representation in Apartheid's Public Education Sector

Gender, Work &Organization, Volume 33, Issue 4, Page 1569-1579, July 2026.
ABSTRACT The South African apartheid regime racially organized society into race categories—one being “Coloured” to denote people of mixed‐race heritage. The term “Coloured,” even in contemporary South Africa, is a contentious categorization given the racist legacy of apartheid. This article documents the lives of “Coloured” women who struggled against

Are West African Heat‐Lows Analogous to Dry Tropical Cyclones?

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Heat‐lows qualitatively resemble dry tropical cyclones (TCs), though their underlying physics has yet to be compared. In this study, we show that West African transient heat‐low climatology correlates well with TC potential intensity generalised over land.

Spatiotemporal Evolution of Hydroclimatic Variables in the Brazilian Semi‐Arid Region Through the Aridity Index and Susceptibility to Desertification

International Journal of Climatology, Volume 46, Issue 8, 30 June 2026.
Over the past 60 years, noticeable changes have been observed in the main hydroclimatological variables, driven by both natural and anthropogenic factors. In the context of climate change, such behaviour may adversely affect the state's economic activities, as well as increase the recurrence of extreme events in the region.

Anthropogenic Pollution Accounts for a Substantial Part of Cloud Condensation Nuclei in North African Dust Layer

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract Cloud condensation nuclei (CCN) modulate the properties and thus the climate effects of clouds. The North African dust plume is an important source of CCN in the North Atlantic trade‐wind zone. Yet, research into the nature and sources of these CCN is sparse, making it difficult to fully assess related cloud effects. Using combined airborne in

Hyperspectral Fingerprinting of Dune Sediments Across the Arabian Peninsula: Insights Into Sediment Provenance and Transport Pathways From NASA's EMIT Data

Geophysical Research Letters, Volume 53, Issue 12, 28 June 2026.
Abstract The Arabian Peninsula encompasses one of the world's most extensive aeolian systems, yet the provenance and transport history of its dune sediments are not well understood. Using hyperspectral data from NASA's Earth Surface Mineral Dust Source Investigation (EMIT), we mapped mineral compositions and abundance patterns across dune fields and ...

Highland Pathways Shape Global Dust Vertical Transport and Its Climate Effects

Geophysical Research Letters, Volume 53, Issue 11, 16 June 2026.
Abstract Highlands govern global dust vertical transport, yet their region‐specific pathways and climatic impacts remain unclear. We found that although dust emissions from highlands are minimal, the dust content in the middle and upper atmosphere over highlands is high, identifying highlands as key dust conduits.

How Well Do CMIP6 Models Simulate the Influence of the West African Westerly Jet on Sahel Precipitation?

International Journal of Climatology, Volume 46, Issue 7, 15 June 2026.
Climate models generally reproduce the WAWJ and August peak but simulate its onset prematurely and too strongly relative to ERA5. CMIP6 simulations struggle to reproduce the jet–precipitation relationship in the Sahel and underrepresent associated moisture transports.
