Normalized difference vegetation index for drought monitoring

open access: yesMAUSAM, 1987
In this study remote sensing technique has been adopted to monitor changes in vegetation cover during the crop growing season and assess the drought conditions. Normalized difference of Landsat Multispectral Scanner (MSS) near Infrared (NIR) band (0.8-1.1 um) and red band (0.6-0.7 um) spectral data has been found useful to monitor the change in crop ...

Estimating vegetation cover from high-resolution satellite data to assess grassland degradation in the Georgian Caucasus [PDF]

open access: yes, 2016
In the Georgian Caucasus, unregulated grazing has damaged grassland vegetation cover and caused erosion. Methods for monitoring and control of affected territories are urgently needed.

Normalized Difference Vegetation Index in the Integration of Conservation Education [PDF]

open access: yesIndonesian Journal of Science and Technology, 2018
Forest plays an important role to support a global environment. Currently, forest degradation occurs in developing countries. Therefore, the excellent strategies to against the forest degradation must be found. One of the best solutions is understanding the information of vegetation condition.

Applicability of the Normalized Difference Vegetation Index (NDVI) in Index-Based Crop Insurance Design [PDF]

open access: yesWeather, Climate, and Society, 2011
Abstract Index insurance is becoming increasingly popular because of its ability to provide low-cost, relatively easy to implement agricultural insurance for vegetation types whose productivity has been notoriously difficult to measure and to farmers in less-developed nations where traditional crop insurance schemes are not reasonable to

A normalized difference vegetation index (NDVI) time-series of idle agriculture lands: A preliminary study [PDF]

open access: yes, 2011
In this paper, the NDVI time-series collected from the study area between year 2003 and 2005 of all land cover types are plotted and compared. The study area is the agricultural zones in Banphai District, Khonkean, Thailand.
