DESERTIFICATION What is desertification? Discover its causes and consequences #society #plastic The UN, which has been fighting desertification since 1994, defines it as the process of land degradation in arid, semi-arid and dry sub-humid areas as a result of various climatic and human factors. With climate change, these factors have only multiplied and it is now considered one of the world's major environmental problems. Desertification threatens different areas of the planet. Desertification threatens different areas of the planet, from the Aral Sea to the Amazon, across all five continents. 6,000 years ago, the Sahara desert, now the largest desert in the world, was grassland covered with vegetation. The oscillations of the Earth's axis turned this area of the planet from an orchard to a sandy area where almost nothing can grow. In that case, we speak of a process of natural desertification which is in contrast to what is happening currently: large areas of the planet are ...

What is greening the desrt?

"Greening the desert" refers to a variety of initiatives and technologies aimed at transforming arid or semi-arid environments into more productive, green landscapes. Here are some aspects and methods associated with this concept: Methods and Technologies: Irrigation Systems: Drip Irrigation: Uses pipes to drip water directly to the roots of plants, minimizing water loss through evaporation. Sub-surface Irrigation: Water is supplied below the soil surface, further reducing evaporation, and promoting deeper root growth. Soil Enhancement: Mulching: Covering soil with organic or inorganic material to retain moisture, reduce evaporation, and improve soil structure. Compost and Manure: Adding organic matter to improve soil fertility and water retention. Plant Selection: Native Species: Using plants adapted to local conditions which require less water. Pioneer Species: Plants that can establish in harsh conditions and help improve soil for other species. Afforestation and Refore...
