<
2021/8/3
Forest clearance in Southeast Asia is accelerating, leading to unprecedented increases in carbon emissions, according to new research. The findings show that forests are being cut down at increasingly...
Unchecked climate change will cause severe drying of the Amazon forest
extreme drought Amazon rain forests Unchecked climate change
<

Amazon rain forests could be at far higher risk of extreme drought than previously thought, according to new research.
Improving the ISBACC land surface model simulation of water and carbon fluxes and stocks over the Amazon forest
water and carbon fl uxes surface model simulation
<
2015/8/6
We evaluate the ISBACC (Interaction Soil Biosphere Atmosphere Carbon Cycle) land surface model
(LSM) over the Amazon forest, and propose a revised parameterization of photosynthesis, including new so...
Analysing Amazonian forest productivity using a new individual and trait-based model (TFS v.1)
Amazonian forest productivity new individual trait-based model
<
2014/12/19
Repeated long-term censuses have revealed large-scale spatial patterns in Amazon basin forest structure and dynamism, with some forests in the west of the basin having up to a twice as high rate of ab...
Estimating soil organic carbon stocks of Swiss forest soils by robust external-drift kriging
Swiss forest soils robust external-drift kriging
<
2014/12/18
Accurate estimates of soil organic carbon (SOC)
stocks are required to quantify carbon sources and sinks
caused by land use change at national scale.
Sensitivity analysis and calibration of a soil carbon model (SoilGen2) in two contrasting loess forest soils
Sensitivity analysis calibration soil carbon model two contrasting loess forest soils
<
2014/12/17
To accurately estimate past terrestrial carbon pools is the key to understanding the global carbon cycle and its relationship with the climate system. SoilGen2 is a useful tool to obtain aspects of so...
Validation of modelled forest biomass in Germany using BETHY/DLR
BETHY/DLR modelled forest biomass
<
2014/12/9
We present a new approach to the validation
of modelled forest Net Primary Productivity (NPP), using
empirical data on the mean annual increment, or MAI, in
above-ground forest stock. T
Conservation Governance and Management of Sagarmatha (Mt. Everest) National Park, Buffer Zone, and Buffer Zone Community Forest User Groups in Pharak, Nepal

The aim of this dissertation is to assess the political ecology of conservation governance and management of Sagarmatha (Mount Everest) National Park (SNP), SNP Buffer Zone (BZ) and the Buffer Zone Co...
Dominant Factors of the Nature Regulating CO2 Release from Boreal Forest Land
Fragmentation Global Warming High-Latitude Forest
<
2013/3/7
Temperature is often considered as a primary factor for microbial decomposition of soil organic carbon. Boreal forests are the large terrestrial carbon pool: if carbon stored in this region is transfe...
Impact of climate change on water balance of forest sites in Rhineland-Palatinate, Germany
climate change water balance forest sites Rhineland-Palatinate
<
2010/9/10
It is expected that the biomass productivity of forest stands will be influenced by global climate change. In order to adapt forest management to this fact a model based approach was developed in coo...
Needle age-related and seasonal photosynthetic capacity variation is negligible for modelling yearly gas exchange of a sparse temperate Scots pine forest
Needle age-related and seasonal photosynthetic capacity variation a sparse temperate Scots pine forest
<
2010/1/21
In this study, we quantified the predictive accuracy loss involved with omitting photosynthetic capacity variation for a Scots pine (Pinus sylvestris L.) stand in Flanders, Belgium. Over the course of...
Autumn temperature and carbon balance of a boreal Scots pine forest in Southern Finland
Autumn temperature carbon balance a boreal Scots pine forest Southern Finland
<
2010/1/21
We analyzed the dynamics of carbon balance components: gross primary production (GPP) and total ecosystem respiration (TER), of a boreal Scots pine forest in Southern Finland. The main focus is on inv...
The use of NOAA/AVHRR satellite data for monitoring and assessment of forest fires and floods

<
2009/12/11
The increasing number of extreme natural phenomena, which are related to the climate variability and are mainly caused by anthropogenic factors, escalate the frequency and severity of natural disaster...
Chronic nitrogen addition causes a reduction in soil carbon dioxide efflux during the high stem-growth period in a tropical montane forest but no response from a tropical lowland forest on a decadal time scale
Chronic nitrogen addition soil carbon dioxide efflux the high stem-growth period a tropical montane forest a tropical lowland forest
<
2010/1/21
Atmospheric nitrogen (N) deposition is rapidly increasing in tropical regions. We studied the response of soil carbon dioxide (CO2) efflux to long-term experimental N addition (125 kg N ha−1 yr&...
