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...

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...

Economists have long argued that payment for the environmental services of forests could contribute to forest conservation and sustainable use. The Clean Development Mechanism (CDM) of the Kyoto Protocol could make this concept a reality by allowing carbon-emitting industries in developed countri...

Carbon sequestration projects conducted as part of community development strategies can offer considerable environmental and social benefits. Such initiatives do have some degree of compatibility with the dual objectives of the Kyoto Protocols’ Clean Development Mechanism (CDM). The lessons learn...

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...

Based on the best available remote sensing data from before 1990, the total area of formally eligible lands in Indonesia for the aff orestation and reforestation (A/R) Clean Development Mechanism (CDM) activities under the Kyoto protocol is about 46 M ha. Priorities for assistance in the developm...

The most prominent international responses to climate change focus on mitigation (reducing the accumulation of greenhouse gases) rather than adaptation (reducing the vulnerability of society and ecosystems). However, with climate change now inevitable, adaptation is gaining importance in the poli...

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...

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...
