Journal ArticleDOI
Land clearing, climate variability, and water resources increase in semiarid southwest Niger: A review
Guillaume Favreau,B. Cappelaere,Sylvain Massuel,Marc Leblanc,Marie Boucher,Nicolas Boulain,Christian Leduc +6 more
TL;DR: In this article, a physically-based, distributed hydrological model showed that land clearing increased runoff threefold, whereas the rainfall deficit decreased runoff by a factor of 2, and that the indirect impacts of land use change on water quantity and quality are much greater than the direct influence of climate variability.
Journal ArticleDOI
Spatial patterns and temporal dynamics in savanna vegetation phenology across the North Australian Tropical Transect
Xuanlong Ma,Xuanlong Ma,Alfredo Huete,Qiang Qiang Yu,Natalia Restrepo Coupe,Kevin Davies,Mark Broich,P. Ratana,Jason Beringer,Lindsay B. Hutley,James Cleverly,Nicolas Boulain,Derek Eamus +12 more
TL;DR: This study investigated biogeographical and inter-annual patterns in savanna phenology along a 1100 km ecological rainfall gradient, known as North Australian Tropical Transect (NATT), encompassing humid coastal Eucalyptus forests and woodlands to xeric inland Acacia woodlands and shrublands and found good convergence between MODIS EVI and tower GEP, thereby confirming the potential to link these two independent data sources to better understand savanna ecosystem functioning.
Journal ArticleDOI
Global change-type drought-induced tree mortality: vapor pressure deficit is more important than temperature per se in causing decline in tree health.
TL;DR: It is shown that increased D exerts a larger detrimental effect on transpiration and NPP, than increased temperature alone, with or without the imposition of a 3-month drought, and correct identification of the causes of global change-type mortality events requires explicit consideration of the influence of D.
Journal ArticleDOI
Precipitation as driver of carbon fluxes in 11 African ecosystems
Lutz Merbold,Jonas Ardö,Almut Arneth,Robert J. Scholes,Y. Nouvellon,A. de Grandcourt,Sally Archibald,Jean-Marc Bonnefond,Nicolas Boulain,N. Brueggemann,C. Bruemmer,B. Cappelaere,Eric Ceschia,Hatim Abdalla M. ElKhidir,B. A. El-Tahir,Ulrike Falk,Jon Lloyd,Laurent Kergoat,V. Le Dantec,Eric Mougin,M. Muchinda,M. M. Mukelabai,David Ramier,Olivier Roupsard,Franck Timouk,Elmar Veenendaal,W. L. Kutsch +26 more
TL;DR: In this paper, the authors report carbon and water fluxes between the land surface and atmosphere in eleven different ecosystems types in Sub-Saharan Africa, as measured using eddy covariance (EC) technology in the first two years of the CarboAfrica network operation.
Journal ArticleDOI
Exploring the potential of MODIS EVI for modeling gross primary production across African ecosystems
Martin Sjöström,Jonas Ardö,Almut Arneth,Nicolas Boulain,B. Cappelaere,Lars Eklundh,A. de Grandcourt,W. L. Kutsch,Lutz Merbold,Y. Nouvellon,Robert J. Scholes,Per Schubert,Jonathan Seaquist,Elmar Veenendaal +13 more
TL;DR: In this article, the authors investigated the relationship between EDD covariance estimated GPP, environmental variables derived from flux towers, MODIS enhanced vegetation index (EVI), and GPP across African savanna ecosystems.
