The increase contrasts with Afghanistan, by far the world's largest supplier of heroin, where the amount of land under opium poppy cultivation has declined over the past three years.
Although wheat remains a major crop, both the amount of wheat and the amount of land devoted to its cultivation have declined while production of canola (rapeseed) and specialty crops such as mustard, peas, and lentils has increased.
The area under cultivation has declined by nearly two thirds since this time largely as a result of the large-scale abandonment of wheat farming in marginal environments.
Its area of cultivation has declined in the past 10 years, but it has been replaced by a new generation of high-quality varieties that are mostly its progeny or relatives.
The fluorescence intensity then increases until 10 h of cultivation and declines thereafter, perhaps reflecting protein degradation.
Intensive cultivation has triggered decline in the soil organic matter (Giannakis et al. 2014).
Saffron cultivation in Europe declined steeply following the fall of the Roman Empire.
The upward trend contrasts with Afghanistan, by far the world's largest supplier of heroin, where the area under opium poppy cultivation has steadily declined over the past three years.
