The Effects of Drought on Vegetation Using using satellite remote sensing and meteorological data (Case study: Qazvin plain)

Setareh Bagheri; Reza Tamartash; Mohammad Jafari; Mohammad Reza Tatian; Arash Malekian

Volume 75, Issue 1 , June 2022, , Pages 1-18


  Plain ecosystem is highly vulnerable to environmental changes, and drought is the most famous ecosystem change driver that is difficult to identify after its occurrence. In this research, to study the slope of vegetation changes against drought, the NDVI index of MODIS images and the SPI index from 2001 ...  Read More

Determination of the relationship between variability of rangeland species forage yield and drought, to forecast forage production using meteorological drought indices

Khaled Osati; Hamed Joneidi; Nahid Azizi

Volume 73, Issue 2 , September 2020, , Pages 239-255


  Prediction of rangeland species forage yield is one of the most effective tools for planning and policymaking of natural resources in each country. Climate variables (precipitation and temperature) play an important role in forecasting rangeland species production. In the present study, the forages yields ...  Read More
