Brazil's humid coastal zone was developed since the beginning with the colonial period. As a consequence, the frontier settlements advanced into the interior during the XVII century. Due to limited natural resources, the semi-arid interior zone was not attractive to the settlers initially, but was gradually developed by cattle grazing. Recently, human activities such as agriculture, grazing and forest utilization have caused serious land degradations

Desertification of the semi-arid interior (Caatinga) of Northeast Brazil has been a serious problem induced by grazing, shifting cultivation and charcoal production. In order to obtain basic information on the desertification, micrometerological observations were conducted in August, 1984, in corn field by cutting Caatinga and inside plant community. In a previous paper, Kashiwagi suggested that the soil of the Caatinga stand is drier than that of the field. This paper describes the measuring data list of both stands

"Amazonia and adjacent lands have tremendous environmental variations, and approaches to the sustainable management of these fragile lands must be different. Geographers Hiraoka, Nishizawa, Sternberg, and Yagasaki have important contributions among the 14 articles"--Handbook of Latin American Studies, v. 57.

Auswertung einer Feld-Studie über das spezifische Stadt-Klima in Rio de Janeiro im Hinblick auf die Auswirkungen der Luftverschmutzung auf die Lufttemperatur im Jahresverlauf am Beispiel der Monate Januar und Juni

This paper focusses on the consumption of firewood by bakeries as a cause of deforestation. The environmental damage associated with the reduction of woodland areas is a severe problem in the semi-arid interior of Northeast Brazil. The Caatinga is the typical vegetation and it covers about 800.000 square kilometres. The original vegetation was probably Mata Seca (dry forest) which has become progressively poorer. Caatinga is used for firewood, charcoal production, and fencing for ranches. Deforestation increased along with the growing settlements during the period of 1950's-1960's and has continued to the present

The results of this empirical analysis of normalized seasonal and interannual rainfall anomalies in Brazil for the period from 1968 to 1985 show an inverse relationship between Northern and Southern Brazil. The facts suggest that other factors such as SST in the Atlantic Ocean and polar outbreaks from Antarctica also influenced the rainfall patterns in Brazil

Results of this empirical analysis of normalized anomalies for an 18 year period from 1968 to 1985 show the inverse relationship in rainfall between Northern and Southern Brazil in most months of the year, best observed in the wet season from December to May
