Satellite technology which helps scientists prevent us from Desertification

Desertification is a type of degradation of land in which the land becomes more arid. Desertification is a direct result of global warming, and approximately 12 million hectares of productive land becomes barren due to desertification annually. Remote sensing technology can be used to measure the extent of desertification. Could you ever thought that in order to fix that stuff scientists start to use satellite technology which helps scientists observe the land?

We have that since a veeeeeeeeeeery long time. It's basically photography at various wavelengths. Also, satellite-based radar is nowadays good enough to register soil erosion / deposition at centimeter precision.

Observing Global Desertification with the Assistance of Space Technology is a very useful method how to keep an eye on desertification, and droughts. This is a vital important system that defines all the mechanisms involved in the process of desertification. The sheer volume of information produced regarding both local and global data allows researchers and scientists to analyse the impact of land degradation and to quantify regression and stabilisation trends over extended periods of time.

Yeah, that`s a good example. I recently read an article about the usage of Space Technology and Coral reef Observation Satellites can be utilised to monitor the coral reef climate in near real time. High-resolution coral reef satellite imagery collected before, during, and after a bleaching event

Why are you opening threads when going to researching the question by yourself?

At least to hear people's opinion about it and, perhaps, learn some new information from those who know more about the subject. Why do you think it's bad?

Yeah, thanks)
I just wanted to start this thread to talk with you about this subject and may be you share some information you have about it ( if you actually have something to add to my thread) By doing that I wann get as much information as it possible about particular point or issue

Now I understand. :bigthumbsup: Your threads felt a bit weird to me...
