World Environment Day

5 June marks World Environment Day, which was established in 1972 by the United Nations to raise people's awareness of our vulnerable environment and other environmental issues.

This year's World Environment Day is hosted by China, with a theme on air pollution, a world-wide issue that is most prominent in the Asia-Pacific region. In this region, air pollution directly or indirectly causes an estimated 4 million deaths (from the 7 million people world-wide). In some major Chinese cities, the air can sometimes be so polluted that even on a ‘clear' sunny day people hardly see the sun. 

Nevertheless, the Chinese government is taking measures to improve the air quality, which is already observed over the last few years from space by dedicated air quality satellite sensors.
Below we show a Proba-V image of 17 May 2019 of Zhanjiang, a city in the south of China with ~6.5 million inhabitants, located at the South Chinese Sea.

The city can be seen as a grey area in the top-middle part of the image. At the bottom of the image the northern part of the Hainan island is visible.

A unique Arctic landscape

Where the Lena River, one of Russia's five longest waterways, flows into the Laptev Sea, it forms a unique delta of three million hectares, 6 500 km river branches, more than 30 000 lakes of varying sizes and over 1 500 islands.

When seen from above, even in this false-colour 100 m image of Proba-V, the water mosaic is enriched by the brightness of the tundra vegetation cover, a mix of nearly 1 000 species of vascular plants, grass, moss, lichen and algae species. The small larch grove, on one of the southern islands, is considered the northern most forest massif of northeast Eurasia.

The Lena Delta and the Ust-Lensky Reserve, that occupies almost half of the delta, are key for the nesting of migrating birds, like the rare Siberian white crane, and supports mammals like the white whale, polar bears, Arctic fox and wild reindeer.

The mixture of land and water and the richness in fauna and flora, all under conditions of (up to 600 m deep) permafrost and the harsh northern climate, make the Delta a unique Arctic landscape and natural heritage to be preserved.
