Desertification is one of the foremost environmental and social-economic problems facing the world. Thus, the observation and early detection of desertification is primary objective for scientific and policy organizations, with geospatial techniques as similar as Remote Sensing (RS) and Geographical Information System (GIS) being a candidate choice for the enlargement of monitoring systems. The present study purposes to assess the desertification caused by Aeolian sand deposits near Vedavathi River in a semi-arid region of Anantapur district, aided by temporal data of satellite imageries of past 28 years (1990 to 2018), were collected and processed. The extent of desertified land for the years 1990, 2000, 2010 and, 2018 is assessed, respectively about 28.22 Km2, 33.86 Km2, 46.30 Km2 and, 58.62 Km2. For the past 28 years, the Aeolian sand desertification is increased into the alarming rates with the land extent of 30.4 Km2.
Aeolian desertification is one of the foremost environmental and social-economic problems facing the world.
The River Vedavathi in the lower reaches is selected for detection of desertified area near to the channel.
The spatial database consisted of change detection layers prepared from Landsat 4, 5, 7 and 8 satellite imageries.
Geometric calculation method is used for detection of desertified area.
The Aeolian sand desertification is increased into the alarming rates with the land extent of 30.4 km2 in reviewed period.
The present study can be used by decision makers to develop economically sustainable plan for the protection and management of river environment.
