This report examines the scientific basis for the use of remotely
sensed data, particularly Normalized Difference Vegetation Index
(NDVI), primarily for the assessment of land degradation at
different scales and for a range of applications, including
resilience of agro-ecosystems. Evidence is drawn from a wide range
of investigations, primarily from the scientific peer-reviewed
literature but also non-journal sources. The literature review has
been corroborated by interviews with leading specialists in the
field. The report reviews the use of NDVI for a range of themes
related to land degradation, including land cover change, drought
monitoring and early warning systems, desertification processes,
greening trends, soil erosion and salinization, vegetation burning
and recovery after fire, biodiversity loss, and soil carbon. This
SpringerBrief also discusses the limits of the use of NDVI for land
degradation assessment and potential for future directions of use.
A substantial body of peer-reviewed research lends unequivocal
support for the use of coarse-resolution time series of NDVI data
for studying vegetation dynamics at global, continental and
sub-continental levels. There is compelling evidence that these
data are highly correlated with biophysically meaningful vegetation
characteristics such as photosynthetic capacity and primary
production that are closely related to land degradation and to
agroecosystem resilience.
