Abstract Most tropical regions are facing historical difficulties of generating biologically reconstructed long‐term climate records. Dendrochronology (tree‐ring studies) is a powerful tool to develop high‐resolution and exactly dated proxies for reconstruction. Owing the seasonal variation in rainfall we expected formation annual tree rings wood West African species. In central‐western part Benin (upper Ouémé catchment, UOC) northeastern Ivory Coast (Comoé National Park, CNP) investigated...
Abstract Fossil‐based emissions can be avoided by using wood in place of non‐renewable raw materials as energy and materials. However, harvest influences forest carbon stocks. Increased may reduce the overall climate benefit use significantly, but is widely overlooked. We reviewed selected simulation studies compared differences amount harvested between scenarios different intensities for three time perspectives: short‐ (1–30 years), mid‐ (31–70 long‐term (71–100 years). Out more than 450 45...
In tropical West Africa, distribution patterns of forest islands in savannas are influenced by fires which occur regularly the grass stratum. Along continuous forest–savanna transects Comoé National Park, change amount and composition non-woody phytomass was investigated from savanna to interior. This correlated with cover vegetation strata above, soil depth, occurrence seasonal surface fires. Phytomass mainly consisted leaf litter forests (about 400 g m−2 at end rainy season, about 600 dry...
The sustainable production of bioenergy is vital to avoiding negative impacts on environmental goods such as climate, soil, water, and especially biodiversity. We propose three key issues that should be addressed in any biodiversity risk-mitigation strategy: conservation areas significant value; mitigation effects related indirect land-use change; promotion agricultural practices with few Focusing concerns, we compared principles criteria set address other social seven standards (defined...
The global carbon neutrality challenge places a spotlight on forests as sinks. However, greenhouse gas (GHG) balances of wood for material and energy use often reveal GHG emission savings in comparison with non-wood reference. Is it thus better to increase production use, or conserve expand the stock forests? products mostly ignore dynamics storage forests, which can be expressed balance (CSBF). For Germany, CSBF 0.25 1.15 t CO2-eq. m−3 assumed. When is integrated into balance, mitigation...
Along eight forest–savanna transects at seven semi-deciduous forest islands in the southern Comoé National Park data on spatial distribution of tree-size classes and environmental parameters (fuel load, shading by upper tree layers, soil depth) were collected. For dominant species, a sequential series was observed from border into interior. At border, Anogeissus leiocarpus most abundant with juveniles (<1 cm dbh) reaching highest density values (mean 502 individuals ha −1 ) outer...
Abstract. Question: How do properties of different vegetation components vary along ecotones semi‐deciduous forest islands, and can the depth edge influence (DEI) be detected using a novel combination analyses? Location: Comoé National Park (CNP), NE Ivory Coast. Methods: Along eight transects at islands tree individuals > 20 cm DBH were mapped. At one transect, shrub down to 1 measured cover species was estimated. Split moving window dissimilarity analysis (SMWDA) regression (MWRA)...

Bioenergy policies affect both the environment and biomass availability for food, feed, fiber on a national international scale. To support policy makers, knowledge methods from different scientific disciplines in form of integrated assessments is necessary. Therefore we developed MILESTONES framework which models links between bioenergy system global land-use as an modeling approach. It builds set three well-tested (MAGNET, LandSHIFT BENSIM). The prototype's functionality was demonstrated...
Abstract Bioenergy is an important renewable energy carrier with uncertainties in future development due to sustainability issues. Its further requires a robust bioenergy strategy on national level. To provide these elements, dedicated approach was developed, which includes new modeling framework, impact assessment, and stakeholder involvement. Demonstrating the example of Germany, four utilization scenarios for period up 2050 have been assessed using seven indicators that cover aspects from...
Reliable density estimations of plant populations and their statistical comparison are fundamental in many ecological studies. Typical sampling methods plotless estimators (PDE) plot counts. A simulation study was performed to examine the power these for densitiesof two populations. The variable area transect estimator, ordered distance Byth’s T-square estimator were considered compared with quadrat count estimator. relative root-mean-squared error bias used explore quality estimators,...

Footprints are powerful indicators for evaluating the impact of bioeconomy a country on environmental goods, domestically and abroad. In this study, we apply hybrid approach combining Multi-Regional Input-Output model land use modelling to compute agricultural footprint (aLF). Furthermore, added information land-use change analysis allocated conversion specific commodities. The German case study shows that aLF abroad is larger by factor 2.5 3 than in Germany. 2005 2010, natural semi-natural...
