"If you've ever smoked a major-brand cigarette, the chances are you've smoked Malawian tobacco," says the BBC. "Virtually every western cigarette uses a bit of the produce from this small southern African nation in its blend."

The battle between cigarette companies and anti-tobacco campaigns poses a challenge for Malawi, one of the poorest nations in the world. In Malawi, tobacco production contributes to 10 percent of GDP and is the second-largest employer in the country.

Proponents of tobacco production argue that tobacco is a crop of choice for farmers because it is easy to grow on marginal soils that yield little else, and earns about seven times more than maize and 22 times more than cotton. In Malawi, revenues from tobacco production are generated from a mere 2 percent of the country’s arable land.

Critics of tobacco production argue that the wealth generated by this resource is not spread evenly across the country. With the price of tobacco constantly fluctuating, those hardest hit are small farmers who are often forced to sell their produce at a loss when tobacco prices fall below market value. According to The Malawi Tobacco Control Commission (TCC), a local government watchdog, it takes US$1 for farm workers to produce a kilogram of tobacco, but that kilo is sold for only US$0.70. As a result, farmers on the big tobacco estates become bonded laborers, forcing whole families to work and repay the landlord. One study found Malawi's tobacco industry employs 78,000 children.

What's not in dispute is that Malawi's tobacco industry is struggling. The government is starting to push alternatives. One is farming mushrooms, where there is already a"brisk local market" — and a potential to meet unmet global demand.
