Status, threads and legal protection possibilities of peatlands in Russia using the example of the peatland Ozero Čistoe, region Lipeck

Abstract: The aim of these investigations was the presentation of the current legal situation for the protection of peatlands in Russia. In parallel, an exemplary investigation of the peatland Ozero Čistoe was performed to analyse the status and the level of risk from the perspective of current nature protection rules in the Oblast Lipeck. Therefore vegetation was described by dominant principles and sorted by vegetation types according KOSKA (2001). They were used as an indicator for the calculation of greenhouse gas emissions (COUWENBERG et al. 2008). In addition, soil samples were taken, in order to determine the peatland’s carbon content. The peatland Ozero Čistoe is part of the protected area „Lipeckij Zakasnik“. It emits about 3.4 to 10.2 t ha-1 of CO2 equivalents per year. The peats of this peatland have a high level of Corg up to 46.5%. During examinating the legislation it occurred that the federal laws for environmental protection (2002) and protected areas (1995) as well as the Water Code (2006) are very important for the protection of peatlands in Russia.Zusammenfassung: Ein Ziel der Untersuchungen war die Darstellung rechtlicher Schutzmöglichkeiten der Moore in Russland. Parallel dazu fand eine exemplarische Untersuchung des Moores Ozero Čistoe im Oblast Lipeck statt, um den Zustand sowie den Gefährdungsgrad aus Sicht aktueller Naturschutzbestimmungen zu analysieren. Dazu wurde die Vegetation des Moores nach Dominanten beschrieben und den Vegetationsformen nach KOSKA (2001) zugeordnet. Sie dienten als Indikator zur Berechnung der Treibhausgasemissionen nach COUWENBERG et al. (2008). Zudem wurden dem Moor Bodenproben zur Kohlenstoffbestimmung entnommen. Das Moor Ozero Čistoe gehört zum Schutzgebiet „Lipeckij Zakasnik“. Insgesamt emittiert es pro Jahr durchschnittlich zwischen 3,4 und 10,2 t CO2-Äquivalente ha-1. Die Torfe dieses Moores weisen hohe Gehalte bis zu 46,5 % Corg auf. Bei der Recherche zur Gesetzgebung zeigte sich, dass in Russland die föderalen Gesetze zum Naturschutz (2002), zu den Naturschutzgebieten (1995) sowie das Wassergesetzbuch (2006) eine besondere Relevanz zum Schutz der Moore haben.DFG, SUB Göttingen, DGMTresearc

C-MIP: An international model inter-comparison simulating organic carbon dynamics in bare fallow soils

IntroductionC sequestration in agricultural soils contributes to the achievement of the climate objectives (e.g. COP-21"s "4per 1000" initiative). Reliable methodologies are needed to assess the soil C sequestration potential of agricultural lands in different management, soil and climate conditions. Simulation models extrapolate C dynamics from current knowledge in both time and space. This is difficult when soil is covered by vegetation,for the continuous input of plant residues and root exudates, and the influence of plants on soil water and temperature dynamics. Long-term bare fallow (LTBF) experiments offer ideal conditions to test models simulating soil organic C dynamics
