[:ja]アレックス・ゲルスト宇宙飛行士がISSから撮影した南アフリカのさとうきびの焼畑の様子です。
さとうきびは南アフリカの重要な輸出作物で、同国は世界で10番目の生産国です。さとうきびは毎年4~12月に収穫時期を迎えます。伝統的な農法では、収穫時に梢頭部および葉を焼却した後に茎を刈り取るという手順を踏みますが、この焼畑による大気汚染の問題が深刻になっています。

[Earthview Wonders] No.586: Southern African Slash-and-Burn🇿🇦
Astronaut Alex Gerst captured from ISS the burning of sugarcane at harvesting in South Africa.
Sugarcane is an important export crop, and South Africa is the world’s tenth largest sugar producer. The cane is harvested over the period April to December each year. In the traditional Slash-and-burn method, treetop and leaves are first burnt and the stem or cane is taken down. The photo shows this smoke before harvesting. This smoke in the traditional method always raises air pollution and environmental discussion.
The local scenery on the ground is as follows.
