Discussion

To discuss the differences between cultures Vavilovianos "and cultures without center Vaviloviano there are two aspects: (i) ecology (ii) the social sciences, (iii) the possibility of collapse and resurrection as of Meyers (2007) and Plachetka / Munoz (2007).

Scenario 1

Agroecology of the mountains is characterized by a diversity microclimatic. The geographic latitude> 45 ° does not allow the arrival of a short-wave solar radiation at the surface of the earth. In the tropical Andes mountain range as high, the net radiation is approaching the global radiation or "solar constant" between 1.93 and 1.98 re cal/cm2/día (Earls 1998, p.3).

Short-wave radiation can reach the surface of the earth, allowing the increased frequency of genetic mutations and the exact demarcation of "climatic spots" in facilities such as Moray (Earls 2006, pp.151-159) to increase the biodiversity of wind pollinators such as Maize.

Complex terraced fields (andenería) as "agricultural amphitheaters" in the Colca Valley near Yanque, 15°39'S,71 °39' W; 3439 meters above sea level, allows the hypothesis of an imitation controlled operation of the tropical mountain as a generator of biodiversity.

Scenario 2

In the language of the peasants cloned potatoes are said to become "tired potatoes" when generations of popes have multiplied asexually. There are customs within communities of small farmers Quechua speakers to strengthen their social networks such as the exchange of varieties of potatoes as "gift varieties" of potatoes. The interview, conducted in May 2006 in the heart of rural education in Palermo Juli, Dep. Puno let us understand that the exchange of germs has something to do with relationships between boys and girls. The exchange is a prevention against the negative effects of seed multiplication in asexual form. The investment of the Incas in the development of crops were substantial.

Scenario 3

The collapse of Wari and Tiwanaku empire is frequently explained by the prolonged drought in the highlands based on the data gathered from the Lake Titicaca and the Qellcaya icecap (Plachetka / Munoz 2007).

Add the fact of the Mega-ENSOs at the beginning of this period.

There are a multitude of explanations for the phenomenon of El Nino, but the interdependence between ENSO El Nino and global warming require special attention.

The correlation between the frequency of ENSO events and global warming, especially in the case of ENSO events at the end of the little ice age (Little Ice Age, LIA), draws attention to the theoretical concept of Earls (2006) about the input energy of a complex system and its transformation into a state of self-criticism with fracázo of the patterns of the autonomous system (Andrade et al 1995, Earls 2006, pp.26-70).

Therefore the impact of the damage in the Amazon jungle fallen dry in terms of the contribution of greenhouse gas by dying forests of that time is to be assessed.

As Vavilov centers i.e. centers of intra-specific crop megadiversity are located on the areas impacted by the ENSO phenomenon, Andrade and David (2003) allow the hypothesis that creating Vavilov centers was a strategy to mitigate the risks of rapid changes in weather conditions and even climate change possibly foreshaddowed and accompanied by Mega-ENSOs.

The Vavilov Center with its wide scope of crop varieties of different plant physiological caracters seems as a cushion of security against abrupt climatic changes.
