Tobacco curing is a critical process in tobacco production that involves the drying of tobacco leaves to reduce their chlorophyll content and enhance their flavour. However, traditional methods of tobacco curing have been associated with significant environmental impacts. This is particularly deforestation due to the heavy reliance on wood as a fuel source This has led to the exploration of sustainable tobacco curing methods that are both economically viable and environmentally friendly.
In recent years, several sustainable practices have been introduced to make the curing process more environmentally friendly. One of these practices involves the redesign of commonly used tobacco curing barns for increased energy efficiency. By optimising the design of these barns, it’s possible to significantly reduce the amount of fuel required for the curing process. This, therefore, reduces the environmental impact. Zimbabwe is adopting this strategy. Moreso, there are designs for energy efficient barns which use less fuel. The Tobacco Research Board in Zimbabwe has designs of low-cost fuel saving curing barns.

Another sustainable practice is the use of alternative fuels for curing. For instance, biomass energy is as a feasible alternative to traditional fuels. Additionally, biomass, such as agricultural residues or wood waste, is renewable and has a lower impact on the environment compared to fossil fuels. The use of intelligent biomass fuel burners has shown promising results as an alternative to coal-fired heating for tobacco curing. In Zimbabwe, alternative energy from waste is in use as a source of energy. Some farmers are now using bricks made from compressed sawdust and grass.
Sustainability also involves the responsible management of tobacco farming. This includes practices such as soil conservation, integrated pest and disease management. Also, the use of responsible water resource management. These practices not only help to reduce the environmental impact of tobacco production, but also contribute to the long-term sustainability of tobacco farming.
In conclusion, sustainable tobacco curing is a multifaceted approach It involves the adoption of energy-efficient methods and the use of alternative fuels. It also uses the implementation of responsible farming practices. By adopting these practices, it’s possible to make curing more sustainable. This therefore reduces its environmental impact and contributes to global sustainability efforts. Zimbabwe is working on ensuring sustainable curing alternatives to keep the farming of the cash crop viable.
