Thought some of the sources it cites are ten years old or more, Wikipedia's Afghanistan; Economy; Agriculture says
Agricultural production is the backbone of Afghanistan's economy and has traditionally dominated the economy, employing about 40% of the workforce as of 2018. The country is known for producing pomegranates, grapes, apricots, melons, and several other fresh and dry fruits. It is also known as the world's largest producer of opium – as much as 16% or more of the nation's economy is derived from the cultivation and sale of opium. It is also one of the world's top producers of cannabis.
ReliefWeb's March 22, 2022 Afghanistan Opium Survey 2021 - Cultivation and Production says:
The production of opiates (opium, morphine, and heroin) is arguably Afghanistan’s largest illegal economic activity. The gross output of the Afghan illicit opiate economy was estimated to be $1.8-$2.7 billion in 2021. The total value of opiates, including domestic consumption and exports, stood at between 9 to 14 per cent of Afghanistan’s GDP, exceeding the value of its officially recorded licit exports of goods and services (estimated at 9 per cent of GDP in 2020).
ABC News's April 4, 2022 Taliban clamp down on drugs, announce ban on poppy harvest and CNN's April 3, 2022 Taliban bans drug cultivation, including lucrative opium are just examples of a story that's received widespread coverage, though it will take time for any drop in poppy production to be documented.
Wikipedia's Heroin says:
In 2015, Afghanistan produced about 66% of the world's opium.
which is a precursor for the production of both heroin and pharmaceutical opiates.
But I'm not asking about the Taliban-led government's announced decision nor its implementation. Instead I'm asking about how the government plans to offset this substantial loss of revenue.
Question: After stopping production of opium, how does Afghanistan's government plan to offset the plan to offset the lost inflow of money associated with their announced policy of stopping opium production going forward?
