Water balance and variations of nutrients and major solutes along a river transect through the Okavango Delta, Botswana
(Botswana Notes and Records; http://journals.ub.bw/index.php/bnr/, 2017-07-05)
Wetland goods and services provide a means of survival for many riparian rural communities in developing countries, particularly in the Sub-Saharan Africa. To sustain the provision of goods and services for human use, ...
The role of vegetation in the Okavango Delta silica sink
(Springer Link; https://link.springer.com, 2014-12-16)
We assessed the role of vegetation and hydrology in the Si cycle in the Okavango Delta. Our results show a large storage of biogenic Si (BSi) in vegetation and the sediments. The biological storage is among the highest ...
Tracing silicon cycling in the Okavango Delta, a sub-tropical flood-pulse wetland using silicon isotopes
(Elservier, https://www.elsevier.com, 2014-07-22)
Chemical weathering of silicate minerals releases elements into solution whereas the neoformation of secondary minerals works in the opposite direction, potentially confounding estimates of silicate weathering rates. Silicon ...
Physicochemical controls of diffusive methane fluxes in the Okavango Delta, Botswana.
(Springer Science, https://link.springer.com, 2015)
Atmospheric methane (CH4) is one of the three key greenhouse gases (GHGs) driving global climate change. The atmospheric concentration of CH4 has increased by about 150 % above pre-industrial levels of 400–700 ppb due to ...
