Large Methane Emission Fluxes Observed From Tropical Wetlands in Zambia

Global Biogeochemical Cycles, Volume 36, Issue 6, June 2022., 2022
Abstract Methane (CH4) is a potent greenhouse gas with a warming potential 84 times that of carbon dioxide (CO2) over a 20‐year period. Atmospheric CH4 concentrations have been rising since the nineteenth century but the cause of large increases post‐2007 is disputed.

ANALYSING THE FINANCIAL VIABILITY OF THE 50MW BANGWEULU SOLAR PLANT IN ZAMBIA USING FINPLAN - EMP-A 2024

The financial viability of the Bangweulu 50 MW Power Plant using FINPLAN was analysed by exploring three scenarios to assess the impact on shareholder dividends in a solar power plant project. The first scenario involved varying electricity prices, indicating that the base price of ZMW 1.5 per KWh resulted in the highest dividends and the shortest ...

A Thermo‐Compositional Model of the African Cratonic Lithosphere

Geochemistry, Geophysics, Geosystems, Volume 23, Issue 3, March 2022., 2022
Abstract Recently, the continually increasing availability of seismic data has allowed high‐resolution imaging of lithospheric structure beneath the African cratons. In this study, S‐wave seismic tomography is combined with high resolution satellite gravity data in an integrated approach to investigate the structure of the cratonic lithosphere of ...

Geodetic Constraints on Cratonic Microplates and Broad Strain During Rifting of Thick Southern African Lithosphere

Geophysical Research Letters, Volume 48, Issue 17, 8 September 2021., 2021
Abstract Southern Africa is typically considered to belong to a single tectonic plate, Nubia, despite active faulting along the southwestern branch of the East African Rift System. We analyze regional Global Navigation Satellite System (GNSS) measurements, and find that the “San” microplate, situated south of the southwestern branch of the East African

Origin, Accretion, and Reworking of Continents

Reviews of Geophysics, Volume 59, Issue 3, September 2021., 2021
Abstract The continental crust is unique to the Earth in the solar system, and controversies remain regarding its origin, accretion and reworking of continents. The plate tectonics theory has been significantly challenged in explaining the origin of Archean (especially pre‐3.0 Ga) continents as they rarely preserve hallmarks of plate tectonics.

Diversity of Quadriacanthus (Monogenea: Dactylogyridae) in the Upper Congo Basin: new geographical records and description of five new species from the gills of Clarias ngamensis (Siluriformes: Clariidae) [PDF]

Zoologia (Curitiba)
Monogenean parasites belonging to Quadriacanthus have never been reported from Clarias ngamensis, but are commonly found on congeners. In view of the specificity of monogeneans, the genetic proximity and the co-occurrence of C.

Testing Models for Upper Mantle Earthquakes in the Tanganyika‐Rukwa Rift, Africa

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 4, April 2026.
Abstract Rifts that initiate in mechanically strong, stable continental lithosphere are characterized by M > 5 earthquakes at depths >35 km near or below the crust mantle interface. Current models for deep rift zone earthquakes invoke elevated pore pressures associated with magmatism, and rapid stressing from magma intrusions.
