چکیده
Temporal NDVI signatures of the following land cover types in the Aral Sea Basin (ASB) were analyzed in MODIS data 2000–2012: Wetlands, bare land, water surfaces, natural vegetation and rainfed agriculture (in mountainous regions), low vegetation, rice cropping systems. Only the last class refers to cropland. All other classes were targeted to separate non-cropland or rainfed agriculture from the irrigated cropland extent. The major observations are schematized at the example of single pixels in Figure S1 and can be summarized as follows:

Cropping Intensity in the Aral Sea Basin and Its Dependency from the Runoff Formation 2000-2012
This study is aimed at a better understanding of how upstream runoff formation affected the cropping intensity (CI: number of harvests) in the Aral Sea Basin (ASB) between 2000 and 2012. MODIS 250 m NDVI time series and knowledge-based pixel masking that included settlement layers and topography features enabled to map the irrigated cropland extent (iCE). Random forest models supported the clas...

متن کاملIrrigation-Induced Environmental Changes around the Aral Sea: An Integrated View from Multiple Satellite Observations
The Aral Sea basin (ASB) is one of the most environmentally vulnerable regions to climate change and human activities. During the past 60 years, irrigation has greatly changed the water distribution and caused severe environmental issues in the ASB. Using remote sensing data, this study investigated the environmental changes induced by irrigation activities in this region. The results show that...
متن کاملIntroducing Satellite Remote Sensing Systems and its Application in Archaeology Case Study: Behshahr Plain- Mazandaran
Human groups have considered the Behshahr plain of Mazandaran in the past Due to its particular geographical shape, location between the Caspian Sea and mountains, and the existence of some rivers in the region. However, our knowledge of this area is limited to several published surveys and archaeological investigation of its ancient sites. No detailed research has conducted on the formation of...
متن کاملReconstructing the Spatio-Temporal Development of Irrigation Systems in Uzbekistan Using Landsat Time Series
The expansion of irrigated agriculture during the Soviet Union (SU) era made Central Asia a leading cotton production region in the world. However, the successor states of the SU in Central Asia face on-going environmental damages and soil degradation that are endangering the sustainability of agricultural production. With Landsat MSS and TM data from 1972/73, 1977, 1987, 1998, and 2000 the exp...
