The African continent is facing one of the driest periods in the past three decades as well as continued deforestation. These disturbances threaten vegetation carbon (C) stocks and highlight the need for improved capabilities of monitoring large-scale aboveground carbon stock dynamics. [...]

16 p, 121.8 KB Human population growth offsets climate-driven increase in woody vegetation in sub-Saharan Africa / Brandt, Martin (University of Copenhagen. Department of Geosciences and Natural Resource Management) ; Rasmussen, Kjeld (University of Copenhagen. Department of Geosciences and Natural Resource Management) ; Peñuelas, Josep (Universitat Autònoma de Barcelona. Departament de Biologia Animal, de Biologia Vegetal i d'Ecologia) ; Verger, Aleixandre (Centre de Recerca Ecològica i Aplicacions Forestals)
The rapidly growing human population in sub-Saharan Africa generates increasing demand for agricultural land and forest products which presumably leads to deforestation. Conversely, a greening of African drylands has been reported, but this has been difficult to associate with changes in woody vegetation. [...]

Department of Geosciences and Natural Resource Management) ; Ndione, Jacques André (Centre de Suivi Ecologique (Dakar, Senegal)) ; Tychon, Bernard (Université de Liege. Water, Environment and Development Unit)
Timely monitoring of plant biomass is critical for the management of forage resources in Sahelian rangelands. The estimation of annual biomass production in the Sahel is based on a simple relationship between satellite annual Normalized Difference Vegetation Index (NDVI) and in situ biomass data. [...]
