The geographical prevalence and potential epidemiology of heartwater in Botswana: implications for planning control under climate change #
(Botswana University of Agriculture and Natural resources, 2012)Heartwater caused by Ehrlichia ruminantium is a widespread animal health problem in Botswana. Although long known to be endemic, its current distribution and possible future occurrence in new areas within the country ... -
The influence of management systems on rangeland conditions under different environments in Botswana #
(Botswana University of Agriculture and Natural resources, 2012)The present study investigated rangeland conditions in communally grazed lands and ranches in different parts of semiarid Botswana. Soils and vegetation assessments were carried out along 23 transects randomly located in ... -
Identification and classification of finger millet (Elcusine coracana ) accessions using morphological traits and DNA finger printing
(Khon Kaen University, 2012)Information on genetic diversity of germplasms is very important for every breeding program, thus evaluation and characterization of germplasms is the first and most important step for any breeding program. Different tools ... -
Pastoralists’ perception and ecological knowledge on savanna ecosystem dynamics in semi-arid Botswana
(Resilience Alliance, 2012)We investigated vegetation dynamics in relation to livestock grazing as perceived by pastoral farmers in different regions of Botswana. A structured questionnaire was used to collect farmers’ understanding of vegetation ... -
