[:ja]NASAの地球観測衛星Terraが撮影したホンジュラスの野焼きです。
焼き畑農業は森林や原野を焼き、農作物の栽培を数年行った後、土地が回復するのを数十年間待って再利用する農法です。地域によっては、十分な休閑期間をとらないまま栽培を行うため、土地がやせてしまい思うように収穫できず、新たな農地を求めて森林を次々に焼くという悪循環が起き、また、煙害による環境問題や二酸化炭素排出による地球温暖化への影響が懸念されています。
ちなみに、ホンジュラスの経済は、アメリカ資本がカリブ海岸熱帯低地で始めたバナナプランテーション産業に依存してきた歴史を持ちます。バナナは多くの労働力を必要としたためサルバドル人の農業移民を引き寄せ、これが隣国エルサルバドルとの軋轢を生んだ歴史があります。

[Earthview Wonders] No.1015: Smoke Over Honduras🇭🇳
NASA’s Terra satellite captured numerous fires over Honduras, many of which were set intentionally to prepare the land for farming (“Slash and burn farming”).
Slash-and-burn agriculture, or fire–fallow cultivation, is a farming method that involves the cutting and burning of plants in a forest or woodland to create a field called a swidden. It is believed that the ash from burning functions as neutralizer of the soil acidity and adjusts nitrogen content.
Honduras was home to several important Mesoamerican cultures, most notably the Maya, before the Spanish Colonization in the sixteenth century. Honduras became independent in 1821 and has since been a republic, although it has consistently endured much social strife and political instability. Honduras is known for its rich natural resources, including minerals, coffee, tropical fruit, and sugar cane, as well as for its growing textiles industry, which serves the international market.
The local scenery on the ground is as follows.
