Beschreibung

Latent desertification is the main cause for the sea level rise and polar melting. Besides it confuses Rain-falls and sets many frighteneing wind-speeds. By knowing the p[henomenon of Laten desertification much environmental problems could be averted.

Latent Desertification and Major environmental harms

What is latent desertification?

Latent desertification is a process on land stretches that reduces the amount of botany present in the stretch as the moisture precipitation from the atmosphere, in all forms rain, snow, due, frost etc. added together, continues to be above 250 mm per year. In latent desertification the reduction of botany is forced in by vectors like human activities and/or presence of herbivores. The region is mostly resilient of its own if left to do so in few seasons provided LD has not crossed over to full scale desertification where the annual precipitation has begun go below 250 mm.

The picture 1 is in a mountainous region full of botany. Its moisture precipitation is far more than 250 mm per year. Lot of trees have been cut to the effect that the lower stretch resembles a desert. Emptied of Botany. It has been forced by human activities. It is a typical example of latent desertification. And presently, the lower stretch is a latent desert.

Latent desertification is found in all cities. Not a single village, even with least human activities, is free of LD. Because human activities reduce the amount of botany-mass. All cities could be called as latent deserts. Because, though the annual precipitation of water in all forms, leaving desert cities aside, exceed by far 250 mm, the amount of main factor the botany, is similar to the deserts.

Latent desertification is distinctly different from desertification. Desertification is a process, in which the moisture precipitation from the atmosphere is regressive in the region. Such that the total precipitation begins to go lesser than 250 mm. per year. Which implies that botany, too, reduces itself on its own. It can be forced by human activities and/or herbivores, also by remote factors which are difficult to assess. The major factor is Latent desertification within and beyond the borders.

Picture 2 is in the Desert at Nile valley. Direct on the banks of Nile palm trees have managed to survive. But higher up one could see the barrenness despite the presence of Nile, which is full of water throughout the year. The moisture precipitation of the region has come down below 250 mm per annum. It is a desert stretch now. Ages ago, it had been a fertile land. It had supplied the needs for high civilisation. Gradually LD gripped the region. It had self-catalysed and had driven the region dry. In this valley LD had been the precursor of the total desertification of the region.

Desert is a stretch of land which has a yearly precipitation of water, in all forms added together, less than 250 mm. In addition there are much less botany or no flora in the stretch. Which comes to far less than 5% of area compared to a fertile stretch. As such even stretches like Antarctica, with ice-layers and ice-bergs hundreds of metres thick, are deserts. So are many high mountains also deserts. Even Mount Everest. The precipitation of moisture per year decides whether a region is a desert or not.

A latent desert on the contrary is a stretch of land which has more than 250 mm moisture precipitation per year. But the amount of botany present in the respective area is less than 5%. It is not a result of natural process; it is forced by human activities or spread of herbivores. The area can be small like a yard and big like a city but must hold the ability to be resilient of its own the moment conditions change.

Pic 3. Above is a region with an annual precipitation that exceeds 2000 mm. Under the rule of nature it should have been thick grove. Now a typical latent-desert. The botany in the stretch had been just removed to be less than 5%. The conversion to latent desert has been not natural, nor caused by distant vectors. It has been forced directly at the place to satisfy a human need.

Examples of Latent Desertification and Latent Desert

The pool in the picture 4 shows there is water precipitation more than 250 mm per year. The area has a Latent Desert: the hill. The land around the hill has much green. But less than it should be under natural conditions. The amount of botany is regressive due to human activities. Therefore the land around the hill is under the pressure of latent desertification, and not a latent desert.

The picture 5 above, though surrounded by ocean water, is a latent desert. It is different from the desert Antarctic. Antarctic has hundreds of metres of thick ice-sheets, yet it is a desert and not a latent desert. Because the precipitation is below 250 mm per year. The picture left is at a rainfall rich tropical island. The botany has got depleted and it is forced not to set root again. The latent desertification of the spot has crossed its margin and has become a latent desert despite frequent heavy rains.

Usage of Latent Desertification to tune climate

At the early stages of human evolution, long time before the receding of ice-age, it was latent desertification that helped people to have relative betterment in life. In the absence of tools even fire, it is in the gaps and passages trampled and rampaged by herds of herbivores, large like elephants and small like goats, that the people made their initial dwellings, cultivations and graze pastures. In addition it gave relative safety from inter-tribal strife and safety from wild animals.

As ages passed they discovered the use of fire. They used it to have tasty food and BQ; get rid of excess waste of botany; putrescent meat waste; to smoke and store food and beside many other usage also to encroach more land. They were able to have fields to cultivate by reducing much natural flora and pastures for domesticated animals.

As ages went past, in the regions reduced of botany, things like stones were found and instinctively people began using it as tool for many purposes. In addition different types of soils were exposed and among them also clay. They saw the usage of clay, both when just dried in the sun and baked with fire. The life’s demands got impulse and galloped relentlessly.

Vegetable planting and ploughing and cultivating of cereals set root with it also domestication of animals and poultry. Precarious hunting and gathering reduced itself as the organised tribal living increased. All led to increased latent desertification, but LD remained within the range of resilience.

The clay-artisanship opened the way to metal-age. With it increased the greed, need, decadence and yearn to power and dominion. Wars had became periodic eventuality and much land were emptied of its valuable botany.
