Rainfall

The roots of cacti spread widely to a large area and absorb the water quickly during rainfalls. Also, the roots grow quickly to widen them for absorption of even more water in rainfall season. All these adaptions allow the cactus to sustain a hot and dry place for longer.

Cacti have brilliant ability to save the water in very hot and dry places where rainfall occurs rarely. This water saving ability is due to their adaptions in many structures. The cactus has either thick leaves or no leaves at all. As a result, the surface-area to volume ratio of the cactus is reduced. Surface-area to volume ratio determines how much water will evaporate. Also, the stem of the cactus is cylindrical or spherical, which also reduce the surface-area to volume.

cies tend to be limited to environments with good rainfall, no dry season and very young soils (through volcanism or glaciation). This is because on older and less fertile soils trees grow too slowly for silviculture to be economic, whilst in areas with a strong dry season there is always a risk of forest fires destroying a tree crop before it matures.

In the areas where "slash-and-burn" is practiced, switching to "slash-and-char" would prevent the rapid deforestation and subsequent degradation of soils. The biochar thus created, given back to the soil, is not only a durable carbon sequestration method, but it also is an extremely beneficial amendment to the soil. Mixed with biomass it brings the creation of terra preta, one of the richest soils on the planet and the only one known to regenerate itself.

over different periods of time, in as yet unexplored locations. He noted that no transition site had been found documenting the shift from what he termed immediate and delayed return social systems. He noted that the full range of domesticated animals (goats, sheep, cattle and pigs) were not found until the sixth millennium at Tell Ramad. Hole concluded that "close attention should be paid in future investigations to the western margins of the Euphrates basin, perhaps as far south as the Arabian Peninsula, especially where wadis carrying Pleistocene rainfall runoff flowed."[26]
