Evaluation of maize yield in flood recession farming in the Okavango Delta, Botswana
(Academic Jornals, http://www.academicjournals.org, 2015-04-09)
Flood recession farming locally known as molapo farming in the Okavango Delta is practiced along the edges of the river channels or seasonally flooded depressions on its fringes. It relies on residual moisture and natural ...
Flood variation and soil nutrient content in floodplain vegetation communities in the Okavango Delta
(South African Journal of Science; http://www.scielo.org.za, 2014-02)
We investigated the influence of hydroperiod variation on soil nutrient content in the Okavango Delta seasonal floodplains. Soil samples were collected from eight zones of homogenous vegetation cover after low and high ...
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 ...
Assessment of benefits and risks of growing Jatropha (Jatropha curcas) as a biofuel crop in sub-Saharan Africa: a contribution to agronomic and socio-economic policies
(Springer Link, https://link.springer.com, 2017-07-17)
In sub-Saharan Africa (SSA), the main goals behind the development of a biofuel industry are employment creation and income generation. Jatropha (Jatropha curcas L.) has emerged as a candidate for biodiesel production. It ...
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 ...
Sap flow variation in selected riparian woodland species in the Okavango Delta, Botswana
(Wiley, https://onlinelibrary.wiley.com, 2017-04-28)
In the tropical Okavango Delta, transpiration by trees is an important process partly responsible for maintaining the basin as a freshwater environment. Quantification of evapotranspiration from terrestrial landforms of ...
