Chile
The diverse climate of Chile ranges from the world's driest desert in the north—the Atacama Desert—through a Mediterranean climate in the center, humid subtropical in Easter Island, to an oceanic climate, including alpine tundra and glaciers in the east and south. According to the Köppen system, Chile within its borders hosts at least ten major climatic subtypes. There are four seasons in most of the country: summer (December to February), autumn (March to May), winter (June to August), and spring (September to November).
The flora and fauna of Chile are characterized by a high degree of endemism, due to its particular geography. In continental Chile, the Atacama Desert in the north and the Andes mountains to the east are barriers that have led to the isolation of flora and fauna. Add to that the enormous length of Chile (over ) and this results in a wide range of climates and environments that can be divided into three general zones: the desert provinces of the north, central Chile, and the humid regions of the south.
Norte Chico, Chile
Norte Chico is a highly mountainous district where distinct ranges or elongated spurs cross the country from the Andes to the coast, forming transverse valleys of great beauty and fertility. The most famous of these is the Elqui Valley. The deep transverse valleys provide broad areas for cattle raising and, most important, fruit growing, an activity that has developed greatly since the mid-1970s. Nearly all Chilean pisco is produced in the near north (Chilean laws defines the pisco as a drink produced in the Near North). The cultivation of the soil becomes possible, at first through irrigation and then with the aid of light periodical rains.
