                      Environment

CLIMATE

       The climate is temperate and with rainfalls along the year, being more intense in spring-summer and drier in winters. The influence of the sea, winds, the duration of the day and night, make differences within the temperate climate: temperate-humid in the northeast, temperate/sub-humid in the central region, semiarid in the southeast and temperate with ocean influence in the Atlantic Coast.

   The maximum average temperatures are between 20º C y 24º C, and the minimum are between 6º C y 10º C.

   The thermic gradient is affected by the latitude, where the temperatures are lower in the south.

  The altitude shows its effects in the mountain area of Bs. As. Province with lower temperatures.

   The higher temperatures in the summer are caused by the influence of the sea where the summers are coolers in
   the Atlantic. The continentality generates larger amplitudes in the west.

   The difference between the longest day, summer solstice in December, and the shortest one, winter solstice ins June, is 4 hours 30 minutes in the north and 6 hours in the south, which generates a strong seasonality.

   The humid winds originated in the anticyclone of the Atlantic, plus other local winds generated near the sea and the
   large basin of the Rio de la Plata give to climate of the coast region a maritime characteristic, regulating the
   temperature. In the other side, the dry and cold winds which come from the Patagonia give to the climate of the west
   and northwest a continental characteristic.

   
   
  Rainfalls become lower from the southeast to the northwest being 900 mm the annual average rainfall in the Delta del Parana and 400 mm in the west-southwest borders of the Pampas plains.


   


ENVIRONMENTAL CHARACTERISTICS

       
      

In old times the area was occupied by grasslands and there were few trees. Nowadays, the fields of cultivation and pasturage occupy almost the total area. Most of the existing forests are made of exotic trees.

    In the last years, the surplus of humidity and a bad natural drainage with a wrong use of the field have generated the permanence of lakes and swamps of great extension which caused environmental changes. At present, the canalization work and a coming period that looks drier are giving back this region its original appearance





The most common crops are cereals and oilseeds, wheat, corn, sunflower, sorghum and soybeans.
    

 

 



Livestock production includes breeds of cattle producing milk and meat
(HOL-Argentine, Shorthorn, Hereford, Angus, Santa Gertrudis, etc..), With campuses of very good quality. There are also large producers of pig races and lesser extent, sheep.
