A vast, arid region characterized by minimal rainfall and a scarcity of rivers, leading to limited vegetation and animal species, often found in parts of Africa, the Middle East, and Australia.
An area where natural vegetation has ceased to thrive due to changes in climate or human activities, resulting in a landscape predominantly composed of sand or rock.
A dry expanse of land that receives less than 200 millimeters of precipitation annually, typically featuring drought-resistant plants like cacti and certain types of hardy flora.
Example:
サハラは広大な砂漠です。
北アフリカに位置し、広大な砂丘や岩地が広がる、地球上で最も乾燥した地域の一つで、極端な気温の変化を伴う自然環境によって特徴づけられる砂漠。
数多くの動植物が生息し、独自の生態系を形成しているが、過酷な気象条件により生存は容易ではない地域。
古代から貿易ルートとして利用されてきた、歴史的な文化交流の舞台であり、さまざまな民族がその周辺に住んでいる。
観 光地としても知られており、美しい夕日や星空、砂丘の風景が多くの人々を魅了する場所。
地形や気候による自給自足が難しく、多くの地域が水源の喪失や砂漠化の影響を受けている環境問題が深刻な地域。
Example:
サハラ砂漠は世界で最も大きい砂漠です。
The process through which an area becomes increasingly arid and devoid of vegetation, often as a result of climatic changes or human activities such as overgrazing and deforestation, leading to the transformation of land into desert-like conditions.
A phenomenon characterized by the loss of biological productivity in drylands, where plants and wildlife decline significantly, ultimately resulting in the degradation of the environment and the expansion of desert areas.
The shift from fertile land to a desert state, often marked by reduced rainfall, soil degradation, and loss of ecosystems, typically influenced by both natural climatic factors and human-induced practices such as agricultural expansion or urban development.
Example:
非常に残念なことに地球は一秒で1900平方メートルが砂漠化している。
