These claims, which took the form of battles against windmills in each trade forum, may be satisfied in an unexpected way when the consequences of environmental imbalances food (third generation phenomena) to materialize, mainly in the central countries. If these events take place in developed countries and food producers, they should increase their imports which, immediately raise the world price of these commodities. At the same time, the persistence of these situations would result in a stronger negotiating position of developing countries producing and exporting primary products, so that they could successfully negotiate volume increases in market access more permanent. This is just one of the many variables that seem feasible in the near future. Thus, the phenomena of first and second generation, although it is unthinkable today, could be moved into a role secondary to the changes that are actually generating the phenomena of third generation, as long as the trend continues to increase in frequency and intensity.

In this situation, cooperation with third world development adds a new basis for their cause, unfortunately, common effects associated with all countries have economic ties that binds. Another aspect is referred to the effect of these phenomena in developing countries. This fact, (as a flood), considering the economic interdependence of the global economy, increasingly force the larger economies (through its agencies) to redouble efforts on investment for infrastructure and provision of these phenomena. The rationale in this case can not be fully humanitarian in nature but security in the supply of certain resources that developed countries derive from these states in development. Today they are health disasters (such as avian influenza), environmental (heavy snowfalls, droughts and floods) or other unexpected events which tend to condition the dynamics in the distribution of world power. Environmental changes are a letter that developing countries must be prepared to use in the near future.

While the theory says little about it may be an important factor in the redistribution of global economic power, followed by shortages of nonrenewable resources. It depends on the sagacity of the developing countries try to take the plunge.

Among the factors that affect soil degradation is erosion caused by rainfall, known as water, causing the formation of gullies (ditches that are produced specifically in soils that have slopes, where they cause the product to drag rainfall flows make increasingly larger dimensions are the same), these gullies rapidly accelerate the degradation. . Therefore we propose the use of the same to produce silage. Silage as a method of forage conservation and utilization of surplus resources as some have a broad future in the present for feeding dairy cattle, and generally for the rest of the herd, especially if this is going to use their own gullies that form in soils. Silage originated in the 1700s, carrying out this practice of food preservation initially by Algerians and the Spanish. These men kept the leftovers from previous years when their harvests were bountiful in abundance, so did those years that surprise attacks on villages were very common (the time of the conquest), implying that their inhabitants had to leave the people were returning after their food intact and well preserved.

Since then and until now has been doing this practice but with a strong scientific interest and so productive. While the practice of ensiling foods today are not very widespread or deeply rooted, it is undeniable practical use, especially in these times when efficient and diversified use of resources is a necessary and indispensable issue in any company for the health of your economy. In addition to the technique which will explain the use is evidence that can make the gullies in the soil where the degree of erosion is high, which can serve as silos for silage making and are therefore able to stop the ongoing process erosion in them. .
