(North-West University, 2011)
Historically the practice of conservation planning has occurred in an ad hoc manner in areas that have no economic or agricultural value. When systematic conservation planning has been implemented it has ensured the ...
Modelling of galactic cosmic ray electrons in the heliosphere
(North-West University, 2012)
The Voyager 1 spacecraft is now about 25 AU beyond the heliospheric termination shock and
soon it should encounter the outer boundary of the heliosphere, the heliopause. This is set to
be at 120 AU in the modulation model ...
Planning sustainable cities through nature-based solutions : perspectives from the Global South
(North-West University (South Africa), 2019)
This research considers nature-based solutions as part of the broader sustainability agenda, as perceived from a Global South perspective. Such considerations emanate from a global phenomenon of urban areas experiencing ...
Reduction of post-harvest losses in tomato using fungal bio-preservative for smallholder farmers
(North-West University (South Africa). Potchefstroom Campus, 2019-05)
Tomatoes (Solanum lycopersicum) are among the important fruits that are widely grown globally. However, they are susceptible to spoilage by fungi due to their high water content and soft endocarp. This spoilage leads to ...
