Soil organic carbon (SOC) sequestration is important in the global carbon cycle and an integral part of many initiatives and policies to mitigate climate change. For efficient targeting of measures leading to SOC sequestration, it is necessary to know the actual SOC content (%) and a realistic ta...


Piikki, KristinSöderström, MatsSommer, RolfSilva, Mayesse daMunialo, SussyAbera, Wuletawu[A Boundary Plane Approach to Map Hotspots for Achievable Soil Carbon Sequestration and Soil Fertility Improvement]A Boundary Plane Approach to Map Hotspots for Achievable Soil Carbon Sequestration and Soil Fertility Improvement

In the arid, low biomass producing areas of Ethiopia, Acacia woodlands suffered a severe degradation due to exploitation for various uses, and conversion to grazing and cultivated lands. However, little is known on the impact of agricultural land uses on soil organic carbon (SOC), total nitrogen ...


Gurmessa, BiyensaDemessie, AmbachewLemma, Bekele[Dynamics of soil carbon stock, total nitrogen, and associated soil properties since the conversion of Acacia woodland to managed pastureland, parkland agroforestry, and treeless cropland in the Jido Komolcha District, southern Ethiopia]Dynamics of soil carbon stock, total nitrogen, and associated soil properties since the conversion of Acacia woodland to managed pastureland, parkland agroforestry, and treeless cropland in the Jido Komolcha District, southern Ethiopia

While Carbon (C) sequestration on farmlands may contribute to mitigate CO2 concentrations in the atmosphere, greater agro-biodiversity may ensure longer term stability of C storage in fluctuating environments. This study was conducted in the highlands of western Kenya, a region with high potentia...


Henry, MTittonell, Pablo A.Manlay, RJBernoux, MartialAlbrecht, A.Vanlauwe, Bernard[Biodiversity, carbon stocks and sequestration potential in aboveground biomass in smallholder farming systems of western Kenya]Biodiversity, carbon stocks and sequestration potential in aboveground biomass in smallholder farming systems of western Kenya

Estimates of the area of swidden fallow secondary forest in Indonesia are inaccurate, partly because swidden agricultural practices giving rise to the secondary forest are heterogeneous. Throughout Indonesia, swidden agriculture is evolving into more intensive land use. A mixed secondary forest t...

Market mechanisms for forest environmental services are a new approach for conservation, but there is also an increasing interest in the derived developmental benefits of these mechanisms. We first propose a conceptual framework for future research on the livelihood impacts of environmental servi...

The carbon to nitrogen response of forest ecosystems depends on the possible occurrence of nitrogen limitation versus possible co-limitations by other drivers, such as low temperature or availability of phosphorus. A combination of nitrogen retention estimates and stoichiometric scaling is used t...


Vries, W. deDu, E.Butterbach-Bahl, Klaus[Short and long-term impacts of nitrogen deposition on carbon sequestration by forest ecosystems]Short and long-term impacts of nitrogen deposition on carbon sequestration by forest ecosystems

Carbon storage and sequestration in tropical mountain forests and their dependence on elevation and temperature are not well understood. In an altitudinal transect study in the South Ecuadorian Andes, we tested the hypotheses that (i) aboveground net primary production (ANPP) decreases continuous...

The authors gratefully acknowledge financial support from the University of Saskatchewan as tuition for the first author and the Natural Science and Engineering Research Council of Canada (NSERC) via the strategic grant from Dr. Vic Timmer for the woodlot research in Tanzania. Also, extra thanks ...
