Carbon stocks and patterns in native shrub communities of Senegal's Peanut Basin

Comparison of Three Kinds of Methods on Estimation of Forest Carbon Stocks Distribution Using National Forest Inventory DB and Forest Type Map

“…이를 보완하기 위해 유럽, 북미 FIGURE 1. Study area 등에서는 NFI 자료, 원격탐사 및 GIS 기술을 결합하여 산림탄소저장량을 추정하기 위한 노 력이 활발히 이루어져왔다 (Brown and Gaston, 1995;Reese et al, 2002;Fournier et al, 2003;Freeman et al, 2006;Huiyan et al, 2006;Labrecque et al, 2006;Blackyard et al, 2007;Gjertsen et al, 2007;McRoberts et al, 2007;Sales et al, 2007;Lufafa et al, 2008;Rahman et al, 2008;Wulder et al, 2008;Fuchs et al, 2009;Magnussen et al, 2009;Meng et al, 2009;Nijland et al, 2009;Zhuang et al, 2009). 특히, 유럽에서는 산림탄소저장량 분포 추정을 위해 위성영상 기반의 k-NN (k-Nearest Neighbor) 기법을 많이 활용하고 있으며 (Tomppo and Siitonen, 1991;Reese et al, 2002;Tomppo et al, 2002;Gjertsen et al, 2007;Tomppo et al, 2008;Magnussen et al, 2009) 우리나라에서도 관 련 연구가 최근에 수행된 바 있다 (Yim et al, 2009;Jung et al, 2010 …”

Vegetation structure, carbon sequestration potential and species conservation in four agroforestry systems in Cameroon (Tropical Africa)

“…Deforestation, biomass burning, conversion of natural to agricultural ecosystems, drainage of wetlands and soil cultivation are the principal causes of greenhouse gas emissions (Lal 2004). Several works have showed the role of agroforestry systems as an opportunity to reduce CO 2 concentrations in the atmosphere by increasing carbon (C) stocks in agricultural lands (Zapfack et al 2002;Albrecht & Kandji 2003;Oelbermann et al 2005;Saint-André et al 2005;Lufafa et al 2008;Takimoto et al 2008;Singh & Lodhiyal 2009;Torres et al 2010;Kumar et al 2011;Hergoualc'h et al 2012;Kuyah et al 2012;Thangata & Hildebrand 2012;Somarriba et al 2013;Kemeuze et al 2015;Manfo et al 2015;Jiagho et al 2016;Noiha et al 2017).…”

Soil attributes functionality and water eutrophication in the surrounding area of Itaparica Reservoir, Brazil

“…The weighted mean value of TOC in the surface horizon of representative soils of the semi-arid region of Brazil is about 0.93% (Salcedo & Sampaio, 2008). The observed low values of TOC (< 0.60%) and TN (< 0.06%) are mainly controlled by the regional climate, apart from soil texture and fertility, which restricts production and incorporation of organic material into soils (Salcedo & Sampaio, 2008) as was observed in the African semi-arid soils (Lufafa et al, 2008;Dossa et al, 2009). Nevertheless, a slight higher content of the TOC is perceived in the clayey soils ( Figure 5G), probably as a result of the association of organic matter with the fine fraction (Hassink, 1997;Eberhardt et al, 2008;McClaran et al, 2008).…”
