[:ja]NASAの地球観測衛星Landsat 8が撮影したパラグアイの首都アスンシオンです。南米を襲っている記録的な旱魃により、パラグアイ川の西岸の耕作地が茶色に染まっているのがわかります。
南米では、この春から旱魃が続き、ブラジル、パラグアイ、ボリビアにまたがる世界最大の湿地「パンタナル」では、7月から大規模な火災が起きています。また、アスンシオンでは2020年9月26日に気温がこの地点の観測史上最高気温42.2Cを記録しました。パラグアイ川の水量はこの半世紀で最低に落ち込み、内陸国であり、対外取引の85%が川を利用して行われるパラグアイの経済に大きな影響が出ています。アスンシオンは、1537年に、ラプラタ川からアルト・ペルー（現在のボリビア）への陸路を探す遠征の途上に、フアン・デ・サラサールらによって建設されました。温暖湿潤気候と熱帯気候の境界線にあり、暑くて湿度の高い夏と、温和な冬に特徴があります。年間平均降水量は1,400mmで、年に80日以上雨が降りますが、今夏は状況が異なります。

[Earthview Wonders] No.1156: Asuncion🇵🇾
NASA’s Landsat 8 satellite captured Asuncion (Asunción), the capital of Paraguay. The image shows the western part of the Paraguay turned brown color due to severe drought.
From this spring, the South America has been suffering from historic drought, and large swathes of forest and wetlands of “the Pantanal,” the world’s largest wetlands that span Brazil, Bolivia and Paraguay, known for their exceptional biodiversity have been ravaged by devastating fires. The Paraguay River has reached its lowest level in half a century after months of extreme drought in the region, exposing the vulnerability of landlocked Paraguay’s economy. Approx. 85% percent of Paraguay’s foreign trade is conducted via the river, which has been depleted because of a lack of rainfall in the Pantanal area of Mato Grosso state in Brazil.
The local scenery on the ground is as follows.
