World Overshoot Day
According to the Global Footprint Network, humanity will have used up its annual natural resource budget on August 1, the earliest Earth Overshoot Day since the global ecological overspending started in the early 1970s. And the costs of this borrowing of future resources is becoming increasingly visible, through deforestation, soil degradation, fresh water scarcity, loss of biodiversity, severe weather and climate change.
Remote Sensing, including our PROBA-V mission, are helping to monitor the land surface worldwide, contributing for instance to records of essential climatic and biodiversity variables, watching out for signs of droughts and desertification and so on.
While most of the Commonwealth of Australia, shown in this week’s image, is semi-arid or desert, it is home to a diverse range of habitats and unique biota, thanks to the continent’s great age, extremely variable weather patterns and geographic isolation. As one of the countries with relatively larger ecological footprint, the Aussie Overshoot Day occurred at the end of March.
