Abstract Vegetation in tropical Asia is highly diverse due to large environmental gradients and heterogeneity of landscapes. This biodiversity threatened by intense land use climate change. However, despite the rich dense human population, often underrepresented global assessments. Understanding how change influences remaining areas natural vegetation therefore important for conservation planning. Here, we used adaptive Dynamic Global Model version 2 (aDGVM2) simulate impacts elevated CO on...
Abstract As part of the REgional Carbon Cycle Assessment and Processes Phase 2 (RECCAP2) project, we developed a comprehensive African Greenhouse gases (GHG) budget covering 2000 to 2019 (RECCAP1 RECCAP2 time periods), assessed uncertainties trends over time. We compared bottom‐up process‐based models, data‐driven remotely sensed products, national GHG inventories with top‐down atmospheric inversions, accounting also for lateral fluxes. incorporated emission estimates derived from novel...
Abstract Anthropogenic climate change is expected to impact ecosystem structure, biodiversity and services in Africa profoundly. We used the adaptive Dynamic Global Vegetation Model (aDGVM), which was originally developed tested for Africa, quantify sources of uncertainties simulated African potential natural vegetation towards end 21st century. forced aDGVM with regionally downscaled high‐resolution scenarios based on an ensemble six general circulation models (GCMs) under two...
South Africa's biomes are characterized by their exceptional biodiversity and they provide important ecosystem services such as food, livestock production, medical plants or fuel wood to people. However, during recent decades, vegetation in Africa experienced substantial changes loss of due habitat loss, intensification land use climate change. The development sustainable management policies requires an understanding interactions between vegetation, change well identification the areas most...
Abstract Aim Shrubs are multistemmed woody plants and a successful growth form in many ecosystems globally. Ecosystems such as the Fynbos South Africa or mediterranean shrublands dominated by dense shrub cover. In savannas, shrubs major vegetation component. Despite importance of at global scale, they are, contrast to trees, often understudied both empirical modelling studies. We define tree strategies trade‐off between water uptake capacity height growth, aim explore if this allows us...
Abstract Africa's protected areas (PAs) are the last stronghold of continent's unique biodiversity, but they appear increasingly threatened by climate change, substantial human population growth, and land‐use change. Conservation planning is challenged uncertainty about how strongly where these drivers will interact over next few decades. We investigated combined future impacts climate‐driven vegetation changes inside African PAs densities land use in their surroundings for 2 scenarios until...
Southern Africa is particularly sensitive to climate change, due both ecological and socio-economic factors, with rural land users among the most vulnerable groups. The provision of information support climate-relevant decision-making requires an understanding projected impacts change complex feedbacks within local ecosystems, as well demands on ecosystem services. In this paper, we address limitation current approaches for developing management relevant socio-ecological human activities. We...
As part of the REgional Carbon Cycle Assessment and Processes Phase 2 (RECCAP2) project, we developed a comprehensive African Greenhouse gases (GHG) budget for period 2010-2019 compared it to over 1985-2009 (RECCAP1) period. We considered bottom-up process-based models, data-driven remotely sensed products, national GHG inventories in comparison with top-down atmospheric inversions, accounting also lateral fluxes. incorporated emission estimates derived from novel methodologies termites,...
Abstract. Vegetation responses to changes in environmental drivers can be subject temporal lags. This implies that vegetation is committed future once stabilize; e.g., physiological processes, structural changes, and composition disturbance regimes may happen with substantial delay after a change forcing has occurred. Understanding the trajectories of such important as they affect carbon storage, structure, community therefore need consideration conservation management. In this study, we...
The study of plant trait variability is critical for understanding ecosystem dynamics and predicting the response vegetation to varying climatic conditions. Understanding factors controlling spatial temporal in traits key addressing responses feedbacks changes climate. In this study, we used adaptive dynamic global model version 2 (aDGVM2) simulate evolution distribution across a wide range edapho-climatic For such, select locations existing different types where situ meteorological eddy...
Abstract. Vegetation responses to changes in environmental drivers can be subject temporal lags. This implies that vegetation is committed future once stabilize. Understanding the trajectories of such important as they affect carbon storage, structure and community composition therefore need consideration conservation management. In this study, we investigate whether transient states represented by a time-shifted trajectory equilibrium states, or if are without analogue conceivable states....
<p>Climate change is expected to cause vegetation in Africa, with profound impacts on ecosystems and biodiversity. Projections of future ecosystem states are constrained by uncertainties regarding relative climate CO<sub>2</sub> fertilisation effects. Rising atmospheric drives change, but also directly affects plant physiological functions via carbon uptake, allocation, water use efficiency, growth. We the adaptive Dynamic Global Vegetation Model...
<p>South Asia is one of the world’s most vulnerable regions to climate change and provides a home approximately 1.7 billion people. South Asian vegetation essential for ecosystem services, biodiversity carbon storage in region. Vegetation distribution biome niches are likely be severely altered by future rising atmospheric CO<sub>2</sub> concentration. Assessing how ecosystems will respond these changes vital importance. We used aDGVM2...
