Telkom has announced that its CEO and executive director Sipho Maseko will step down on 30 June 2022. The telecoms company said the process to appoint a successor is well underway and a designated group CEO will be announced in the not too distant future.
It is possible that cooking oil prevented more looting in South Africa in the last week than the president, the ANC, the intelligence community, the army and the police combined. This, without question, says something about the versatility of the product. It says even more about the state of the state.

Performance Media across Search, Social and Programmatic platforms is the single fastest growing area of digital media in South Africa. Combine that with the detailed analysis of campaign management, tagging and ad operations, and it becomes apparent that these highly specialist functions require a highly specialised unit.
The Transnet Port Terminals website has been hacked, implying that all companies under Transnet have been affected. All Transnet websites were down at the time when reporting was done for this SA Trucker article. The publication cited sources who requested to remain anonymous because they are not allowed to speak to the media.
The Covid-19 pandemic has hit South Africa's small business sector hard and there are grim statistics to bear this out. Those statistics will not be repeated here. After all, if you are a small business owner setting out on the road to recovery, the last thing you probably want is more details of the toll the pandemic has taken on small enterprises. Far more useful would be some good, solid tips on how to build back better after any business setbacks.ByAmeen Hassen

As a scientist focusing on agricultural land use and adviser to several farm organizations, I have the privilege of working alongside farmers who have figured out how to do just that. I am enthusiastic about farmer-led solutions to climate change. What does this look like?

Restore strips of native plants around farm fields
Plants remove carbon from the atmosphere as they grow, and soil can soak up carbon and store it. These abilities are key to climate solutions that crop farmers can readily deploy today.
Seeding narrow strips of land within and around crop fields with native plants is an effective and affordable way to make farming more climate-friendly. Iowa State University’s STRIPS Project has shown that this technique reduces erosion and nutrient loss from soil and supports birds and insects.
Nitrous oxide forms under anaerobic conditions – environments without oxygen, such as low-lying wet areas of farm fields, where it is produced by soil microbes. The easiest way to keep it from forming is to avoid fertilizing these areas, which amounts to feeding the microbes.
Prairie strips help reduce nitrous oxide emissions by soaking up nitrogen fertilizer that runs off of adjacent cropland. They also can store carbon in soil in two ways: by trapping sediment moving down slopes, and by removing carbon dioxide from the atmosphere through photosynthesis and storing this carbon in plant roots and soil.
On April 21, 2021, Agriculture Secretary Tom Vilsack announced that the agency will expand Conservation Reserve Program enrollment and offer higher payment rates for participating. The department is also creating a new Climate-Smart Practice Incentive to promote strategies that sequester carbon and reduce greenhouse gas emissions. I hope this measure will promote national awareness of prairie strips, which today are known mainly in Iowa and neighboring states.
Turn soggy spots into wetlands
Since nitrous oxide emissions come mainly from wet zones, letting these areas remain as wetlands is another climate-smart strategy. Soggy areas tend to yield poorly in most years, and farmers rarely recoup their investment in cropping them. However, wetlands can be troublesome to farm around, which is why many farmers try to drain and farm through them.
Another USDA initiative, the Farmable Wetland Program, pays farmers to take previously farmed wetlands and buffer areas out of production for 10 or more years. Enrollment is currently capped at 1 million acres. A climate-smart agricultural policy could expand the program by removing the acreage cap and boosting incentive payments.

Promote perennial crops, especially grasses
All crops are not equal when it comes to mitigating climate change and conserving the environment. Perennials – including various types of grasses, shrubs and trees – provide more ecological benefits than annual crops like corn, wheat and soybeans. But they receive less government support.
Just like annual garden plants, annual crops must be replanted every year. Perennial crops live for multiple seasons, so raising them requires fewer climate-warming inputs, such as fertiliser and fuel to power tractors. These crops develop deep roots that soak up water in soggy spots and help stabilize soil on sloping land.
Many fruits, vegetables and forage crops are perennials. Examples include apples, alfalfa, grapes and asparagus. Researchers are working to develop perennial versions of grains, legumes and oilseeds such as sunflowers.
There are many opportunities to expand cultivation of perennial crops. Grasses and forbs – flowering plants with stems and leaves, such as bee balm – are less expensive to establish and grow than woody crops like willow, and offer farmers more management flexibility.
I direct a transdisciplinary team called C-CHANGE, funded by USDA, that is working with farmers to create and expand market-based value chains for perennial grasses. We are helping farmers plant mixtures of native perennial grasses and forbs to build soil health where it has been eroded and protect environmentally sensitive areas.
The grasses can ultimately be harvested and processed in biodigesters – devices that break down organic materials to produce energy – along with manure or food waste. This cycle will yield electricity or biomethane from renewable sources that can displace fossil-based energy sources on or off of farms. It also will produce liquid and solid materials that can be used as organic fertilizers, along with other valuable products.
Biodigestion is widely used in Europe but underdeveloped in the U.S. We expect that the value chain we’re creating will embed it in a larger cycle that creates a market for protective perennial crops, reduces fossil fuel use and returns carbon to the soil.
When I think of climate-smart agriculture, I picture farmlands with lots of perennial vegetation smartly integrated as prairie strips, wetlands and crops. Federal policies and programs that can make such landscapes a reality are already in place. With concerted efforts and investments, they could be expanded to achieve a pace and scale that will help address climate change.
