Rain-Use-Efficiency: What it Tells us about the Conflicting Sahel Greening and Sahelian Paradox

Cécile Dardel, Laurent Kergoat, Pierre Hiernaux, Manuela Grippa, Eric Mougin, Philippe Ciais, Cam-Chi Nguyen
2014 Remote Sensing  
Rain Use Efficiency (RUE), defined as Aboveground Net Primary Production (ANPP) divided by rainfall, is increasingly used to diagnose land degradation.  ...  Yet, the outcome of RUE monitoring has been much debated since opposite results were found about land degradation in the Sahel region.  ...  Introduction RUE and the Desertification/"Re-greening" Debate Rain Use Efficiency is defined as the ratio between net primary production (NPP), or aboveground NPP (ANPP), and rainfall.  ...

What Four Decades of Earth Observation Tell Us about Land Degradation in the Sahel?

Cheikh Mbow, Martin Brandt, Issa Ouedraogo, Jan de Leeuw, Michael Marshall
2015 Remote Sensing  
Acknowledgments This work has been funded by the BIODEV project implemented in Burkina Faso and Sierra Leone and the CG Research Programme CRP 6.3 and 6.4 on Forest trees and agroforestry/Ecosystem Services  ...  in some areas (Sahel Paradox) [63] .  ...  Theoretically, Rain Use Efficiency (RUE) can normalize the inter-annual variability in NPP due to rainfall variability, and consequently provide an index of degradation that is independent of the effects  ...
