TLDR
In this paper, the authors examined the relationship between vegetation productivity and the annual integrated NDVI (iNDVI) and found that there are large differences between the NDVI- vegetation productivity relationships, and these differences can be linked to species composition.About:

Re-Greening Sahel: 30 Years of Remote Sensing Data and Field Observations (Mali, Niger)
TL;DR: In this paper, a linear regression analysis performed between spatially averaged seasonal NDVI and a weighted average of field measurements explains 59% of the variability for the Gourma region over 1984-2011, and 38% for the Fakara region over 1994-2011.

Assessing Land Degradation/Recovery in the African Sahel from Long-Term Earth Observation Based Primary Productivity and Precipitation Relationships
Rasmus Fensholt,Kjeld Rasmussen,Per Skougaard Kaspersen,Silvia Huber,Stéphanie Horion,Else Swinnen +5 more
TL;DR: This paper demonstrates that the use of the standard EO-based proxy for ANPP, summed normalized difference vegetation index (NDVI) over the year, and the blended EO/rain gauge based data-set for annual precipitation (Climate Prediction Center Merged Analysis of) is feasible.

Quantifying the effectiveness of ecological restoration projects on long-term vegetation dynamics in the karst regions of Southwest China
Xiaowei Tong,Kelin Wang,Yuemin Yue,Martin Brandt,Bo Liu,Chunhua Zhang,Chujie Liao,Rasmus Fensholt +7 more
TL;DR: A remote sensing based approach to evaluate the long-term efforts of the ERPs started in 2000 was proposed, and counties with high project effectiveness in spite of complex natural conditions were identified, while counties with negative vegetation trends despite relatively favorable conditions and high investments were also distinguished.

Remote sensing of vegetation dynamics in drylands: Evaluating vegetation optical depth (VOD) using AVHRR NDVI and in situ green biomass data over West African Sahel
Feng Tian,Feng Tian,Martin Brandt,Yi Y. Liu,Aleixandre Verger,Torbern Tagesson,Abdoul Aziz Diouf,Kjeld Rasmussen,Cheikh Mbow,Yunjia Wang,Rasmus Fensholt +10 more
TL;DR: In this paper, the authors assess the capability of a long-term VOD dataset (1992-2011) to capture the temporal and spatial variability of in situ measured green biomass (herbaceous mass and woody plant foliage mass) in the semi-arid Senegalese Sahel.

Biomass Productivity-Based Mapping of Global Land Degradation Hotspots
TL;DR: Using the long-term trend of biomass productivity as a proxy of land degradation at global scale, the degradation hotspots in the world across major land cover types were identified in this article.

Climate Change 2001: Impacts, Adaptation, and Vulnerability
TL;DR: In this paper, the authors set the stage for impact, adaptation, and vulnerability assessment of climate change in the context of sustainable development and equity, and developed and applied scenarios in Climate Change Impact, Adaptation, and Vulnerability Assessment.

Red and photographic infrared linear combinations for monitoring vegetation
TL;DR: In this article, the relationship between various linear combinations of red and photographic infrared radiances and vegetation parameters is investigated, showing that red-IR combinations to be more significant than green-red combinations.

Climate change 2007 : impacts, adaptation and vulnerability
TL;DR: In this paper, the authors present a cross-chapter case study on climate change and sustainability in natural and managed systems and assess key vulnerabilities and the risk from climate change, and assess adaptation practices, options, constraints and capacity.

A soil-adjusted vegetation index (SAVI)
TL;DR: In this article, a transformation technique was presented to minimize soil brightness influences from spectral vegetation indices involving red and near-infrared (NIR) wavelengths, which nearly eliminated soil-induced variations in vegetation indices.

Increased plant growth in the northern high latitudes from 1981 to 1991
TL;DR: In this paper, the authors present evidence from satellite data that the photosynthetic activity of terrestrial vegetation increased from 1981 to 1991 in a manner that is suggestive of an increase in plant growth associated with a lengthening of the active growing season.
