BACKGROUND A regional-scale sensitivity study has been carried out to investigate the climatic effects of forest cover change in Europe. Applying REMO (regional climate model of the Max Planck Institute for Meteorology), the projected temperature and precipitation tendencies have been analysed for summer, based on the results of the A2 IPCC-SRES emission scenario simulation. For the end of the ...
Common techniques currently used for afforestation in the Mediterranean basin consider the pre-existing vegetation (mainly shrubs) as a source of competition for trees, and consequently it is generally eliminated before planting. Nevertheless, it has been demonstrated that woody plants can facilitate the establishment of understory seedlings in environments that, like the Mediterranean area, ar...
The large global extension of arid and semi-arid regions together with their widespread degradation give these areas a high potential to sequester carbon. We explored the possibilities of semi-arid ecosystems to sequester carbon by means of rangeland exclusion and afforestation with Pinus ponderosa in NW Patagonia (Argentina). We sampled all pools where organic carbon accumulates in a network o...
A multitude of studies analyzed the dynamics soil organic carbon (SOC), but their methodology does not provide sufficient understanding differential impact artificial and natural afforestation on SOC dynamic. We investigated following (AR) (NQ) abandoned farmland (AF) in China’s Loess Plateau an attempt to evaluate effects these methods. characterized structure stoichiometry using stable isotop...
Afforestation can play a significant role in greenhouse gas emission reduction through increased carbon (C) sequestration the biomass and soil. However, its environmental effects, especially changes soil characteristics as result of afforestation, are still poorly understood. In this work, we studied response grassland soils derived from two different parent materials to afforestation. We measu...
Afforestation of contaminated areas is considered as a possible strategy for reduction of contaminations. In the present study, the effects of lead (Pb) and cadmium (Cd) were investigated on chlorophyll fluorescence parameters (Fv/Fm, Fo, and Fm), photosynthetic pigments (chlorophyll a, b, and total chlorophyll), and proline in one-year-old seedlings of Celtis caucasica and Robinia pseudoacacia...
gauge instrument or prism was introduced, which significantly expedited the process. There was no national forest resource information in China during 1963–1972. The first NFI was performed during 1973–1976, in which a stratified systematic sampling technique was used to locate NFI sample plots. Each province, autonomous region, or municipal city designed one or more sampling populations accord...
Abstract. Land cover in sub-polar and alpine regions of northern eastern Europe have already begun changing due to natural anthropogenic changes such as afforestation. This will impact the regional climate hydrology upon which societies these are highly reliant. study aims identify impacts afforestation/reforestation (hereafter afforestation) on snow snow-albedo effect highlight potential impro...
