Effects of annual flooding on dissolved organic carbon dynamics within a pristine wetland, the Okavango Delta, Botswana
(The Society of Wetland Scientists, 2005)In the Okavango Delta in Botswana, dissolved organic matter (DOM) transport is controlled by the slow movement of an annual flood ‘pulse’ across permanently and seasonally flooded wetlands, known respectively as the ... -
Fire activity on drylands and floodplains in the southern Okavango Delta, Botswana
(Elsevier; http://www.elsevier.com/wps/find/journaldescription.cws_home/622855/description#description, 2006-05-08)Satellite imagery derived fire history data for the southern Okavango Delta, Botswana from 1989 to 2003 were used to analyse the temporal and spatial distribution of fires and to assess changes in fire activity. Maximum ... -
Global monitoring of wetlands - the value of ENVISAT ASAR Global mode
(Elsevier, 2008-03-17)This paper elaborates on recent advances in the use of ScanSAR technologies for wetland-related research. Applications of active satellite radar systems include the monitoring of inundation dynamics as well as time series ... -
Interactions between fire and flooding in a southern African floodplain system (Okavango Delta, Botswana)
(Springer: http://www.springerlink.com, 2006)A series of 98 satellite images was analysed to reconstruct the fire and flood history of a floodplain system in southern Africa(Okavango Delta, Botswana). The data was used to investigate interactions between fire and ... -
A review of the freshwater diversity in the Okavango Delta and Lake Ngami 1 (Botswana): taxonomic composition, ecology, comparison with similar 2 systems and conservation status
(Springer Link, https://www.springer.com/journal/27/, 2023-10-11)Freshwater organisms in the Okavango Delta and Lake Ngami (Botswana) provide direct and indirect benefits to people and the economy of the region. However, their existence could be potentially threatened by human activities ... -
Simulation of DOM fluxes in a seasonal floodplain of the Okavango Delta, Botswana
(Elsevier, www.elsevier.com/locate/ecolmodel, 2007)In order to examine dissolved organic matter (DOM) fluxes in seasonal wetland systems that expand and contract seasonally, a time-variable model of dissolved organic carbon (DOC) was developed for a seasonal floodplain ... -
State interests and multilateral cooperation: thinking strategically about achieving 'wise use' of the Okavango Delta system
(Elsvier, www.elsevier.com, 2003)This paper explores possibilities for achieving 'wise use’, defined as the sustainable utilization of resources of the Okavango Delta system, within the framework of the Ramsar Convention on Wetlands of International ... -
The tropical African mercury anomaly: lower than expected mercury concentrations in fish and human hair
(Elsevier, 2011-02-20)Mercury is a neurotoxin and global pollutant, and wetlands and newly flooded areas are known to be sites of enhanced production of monomethylmercury, the form of mercury that is readily biomagnified in aquatic food chains ... -

Variation of physico-chemical parameters along a river transect through the Okavango Delta, Botswana
(Tailor and Francis Online; https://www.tandfonline.com, 2016-06-07)The Okavango Delta depends on water quantity and quality to sustain its ecosystem services. Whereas many studies have been carried out on its hydrology, few have been done on water quality in the delta. Water pH, electrical ... -
A vegetation-based hierarchical classification for seasonally pulsed floodplains in the Okavango Delta, Botswana
(Taylor & Francis, http://taylorandfrancis.com, 2011-12-11)A classification scheme is presented for seasonal floodplains of the Boro-Xudum distributary of the Okavango Delta, Botswana. This distributary is subject to an annual flood-pulse, the inundated area varying from a mean ...
