_1 Year after a field is put lying fallow, it is colonized by seasonal plants that last only for a year. Wildlife is limited to insects and small animals which pass by looking for seeds.
_5 Years later, some shrubs and long-lasting herbaceous appear, but most of the plants are still short-lived. We find also termites’ nests and dens dug by the rodents there.
_10 Years the long-lasting weeds begin to expand, and real trees grow here and there. The jackal and the hare hide among shrubs. Finally the old field distinguishes itself no more than a strong oasis, and we find any sorts of plants and animals; big and small ones, herbivores, as well as their predators there.
According to Pr. Allan Savory, researcher and developer in holistic techniques, if we could re-green half of the desert borders and the meadows of the world, the carbon preserved in grounds would allow us to return to the environmental state of the preindustrial era.
While feeding the whole humanity.
