Transcript of Deforestation in amazon
INTRODUCTION
AREA= AMAZON (RIO BRANCO,BRAZIL)
The Amazon rainforest is the world’s largest tropical
rainforest, famed for its bio diversity. The
rainforest is seen as a resource for cattle pasture,
valuable hardwoods, housing space, farming
space, road works and medicines. Scientists
using NASA satellite data found in 2006 that
clearing for mechanized cropland had become a
significant force in Brazilian Amazon
deforestation. This change in land use may alter
the region's climate
We collected the datasets i.e. images from the
internet. The datasets were then analyzed in
ERDAS IMAGINE. By interpreting the images the
deforestation was evident. Images were digitized
for ease of analysis.
ABSTRACT:
We used Erdas Imagine 2013 to observe the
deforestation of Amazon Forest by taking in
account its particular area of Rio Branco having
latitude 9˚ 58’ 31’’ and longitude 67˚ 49’ 29’’. We
took the datasets from internet
(earthexplorer.usgs.gov), performed stacking,
subsetting, georeferencing, area calculations, and
used other such tools to observe the
deforestation of particular area and its conversion
for nonforest use.
Steps followedClassification Using different techniques
Calculation of area
Checking Deforestation
Concluding regarding observations
Prediction Of Deforestation in 2030
RESULTS
% change in Vegetation =11122.2−10419.4
11122.22
*100
=6.31%
So 6.31% of vegetation is lost due to
deforestation from 1990 to 2000
