New Technologies
In addition to replenishing forests, the government, through the TRB, is researching into, developing and promoting adoption of more energy-efficient curing options as well as renewable curing systems.
One of the new technologies being promoted is the rocket barn, which is suitable for smallholders. Invented in Malawi and adopted and further developed by the TRB, the barn utilizes 4 kg of wood to cure 1 kg of tobacco whereas the conventional barn consumes 9 kg of wood to cure 1 kg of the crop. The small diameter furnace, introduced locally in 2014, also cures 0.5 ha of crop in a five to six day cycle compared to seven to 10 days in a conventional barn.
There is also the larger, more expensive, twin-turbo barn, which is the most energy efficient model so far. According to the TRB, this technology utilizes any flammable material, including sawdust, wood and liquefied petroleum gas. A farmer needs about 1.5 kg of firewood to produce 1 kg of tobacco.
In September this year, the TIMB launched a tobacco value chain development plan that seeks to promote use of solar and other renewable technologies to gradually phase out heavily polluting wood and coal-based curing systems.
The Zimbabwe Tobacco Association’s chief executive, Rodney Ambrose, regretted the teething problems that have affected the FCZ managed program.
For three years since its launch, he said, officials bickered over how the fund was to be administered. Many opportunities were missed over the years the tobacco levy was deducted but kept in the TIMB bank account as officials differed.
“Then in 2020, a decision was made that [the] Forestry Commission of Zimbabwe should do the afforestation,” he said.
The Tobacco Farmers Union of Zimbabwe’s president, Believe Tevera, also a farmer in Mount Darwin, Mashonaland Central Province, is also critical of the FCZ initiative. He said it was high time they saw real environmental remedy though the levies as the rate at which degradation is happening was not congruent with the steps that are being taken to correct the problem.
“In Mount Darwin, we have been advocating to have that money channeled through the promotion of community-owned woodlots because we have wetlands. We can actually utilize these wetlands by planting gumtrees (eucalyptus). We can also grow the trees in gullies as there is a lot of soil erosion, which is being caused by deforestation,” he said.
