Estimation of vegetation traits with kernel NDVI

open access: yesISPRS Journal of Photogrammetry and Remote Sensing, 2023
Vegetation indices computed from spectral signatures are vastly used for monitoring the terrestrial biosphere. Indices are convenient proxies for canopy structure, and leaf pigment content, and consequently to estimate the photosynthetic activity of vegetation.

NDVI relationship to monthly evaporation [PDF]

open access: yesGeophysical Research Letters, 1998
Normalized difference vegetation indices (NDVI), calculated from Landsat‐MSS images, were correlated with monthly total precipitation and estimates of monthly evaporation in a prairie environment. The highest value of the correlation coefficient (r=.80) was obtained between the monthly mean NDVI and estimated evaporation of the preceding month.

The role of land cover change in Arctic-Boreal greening and browning trends [PDF]

open access: yes, 2019
Many studies have used time series of satellite-derived vegetation indices to identify so-called greening and browning trends across the northern high-latitudes and to suggest that the productivity of Arctic-Boreal ecosystems is changing in response to ...

Mapping Evapotranspiration, Vegetation and Precipitation Trends in the Catchment of the Shrinking Lake Poopó

open access: yesRemote Sensing, 2019
Lake Poopó is located in the Andean Mountain Range Plateau or Altiplano. A general decline in the lake water level has been observed in the last two decades, coinciding roughly with an intensification of agriculture exploitation, such as quinoa ...

Empirical evidence for impacts of internal migration on vegetation dynamics in China from 1982 to 2000 [PDF]

open access: yes, 2008
Migration is one of the major socio-economic characteristics of China since the country adopted the policy of economic reform in late 1970s. Many studies have been dedicated to understand why and how people move, and the consequences of their welfare ...

A GIS Assessment of the Green Space Percentage in a Big Industrial City (Dnipro, Ukraine)

open access: yesEkológia (Bratislava), 2023
Green spaces in an industrially polluted city are extremely important for the physical activity and mental health of its inhabitants. The study aim was to analyze the urban green space dynamics and the greening degree of different functional zones ...

Assessing water availability in Mediterranean regions affected by water conflicts through MODIS data time series analysis [PDF]

open access: yes, 2019
Water scarcity is a widespread problem in arid and semi-arid regions such as the western Mediterranean coastal areas. The irregularity of the precipitation generates frequent droughts that exacerbate the conflicts among agriculture, water supply and ...

Analysis of urban growth effects on Land Surface Temperature (LST) increase using GIS: A case study of Chelghoum El Aïd city (1984-2024) [PDF]

open access: yesGlasnik Srpskog Geografskog Društva
The city of Chelghoum El Aïd has experienced rapid urban growth, primarily driven by a major urbanization event. This expansion has prioritized the development of natural and undeveloped spaces, rather than investing in urban infrastructure.
