Welding remains the most important metal joining technology available to the manufacturing industry today, with widespread application in fields as diverse as microelectronics, power generation, structural design and the petrochemical industry. While global demand for consistently high quality welds in a wide variety of advanced materials and applications continues to grow, is the South African manufacturing industry positioned to take advantage of the opportunities offered?

Story
In a first for precision agriculture, University of Pretoria (UP) researchers, in association with collaborators from the Council for Scientific and Industrial Research (CSIR), have produced maps of smallholder farms in Gauteng that highlight maize plants in green and weeds in red. The maps were shared with farmers to enable them to pinpoint and eradicate weeds with more precision.

Farmers not only save time and money by cutting down the cost and effort required to manage weeds, but also limit the environmental impact of using harmful weed-killing chemicals by using satellite data and imagery.
