Abstract. This paper provides a comprehensive description of the newest version Dynamic Global Vegetation Model with managed Land, LPJmL4. model simulates – internally consistently growth and productivity both natural agricultural vegetation as coherently linked through their water, carbon, energy fluxes. These features render LPJmL4 suitable for assessing broad range feedbacks within impacts upon terrestrial biosphere increasingly shaped by human activities such climate change land use...
Summary Anthropogenic global change compromises forest resilience, with profound impacts to ecosystem functions and services. This synthesis paper reflects on the current understanding of resilience potential tipping points under environmental explores challenges assessing responses using experiments, observations models. Forests are changing over a wide range spatio‐temporal scales, but it is often unclear whether these changes reduce or represent point. Tipping may arise from interactions...
Abstract. Deforestation in Amazon is expected to decrease evapotranspiration (ET) and increase soil moisture river discharge under prevailing energy-limited conditions. The magnitude sign of the response ET deforestation depend both on regional patterns land-cover change (LCC), as well climate CO2 levels. On one hand, elevated decreases leaf-scale transpiration, but this effect could be offset by increased foliar area density. Using three LCC scenarios specifically established for Brazilian...
Summary Forests around the world are changing as a result of human activity. These changes have substantial impacts on resilience forests, possibly pushing them towards tipping points. The objective this Special Feature is to present research that fosters understanding forest and potential points under global change. This editorial summarizes key findings seven papers in puts wider context thinking. Synthesis . contributions show useful concept understand ecosystem change but we develop...
Abstract Global change includes multiple stressors to natural ecosystems ranging from direct climate and land‐use impacts indirect degradation processes resulting fire. Humid tropical forests are vulnerable projected possible synergistic interactions with deforestation fire, which may initiate a positive feedback rising atmospheric CO 2 . Here, we present results multifactorial impact analysis that combined an ensemble of models feedbacks accidental fires quantify changes in Amazon Basin...
Abstract. Floodplain forests, namely the Várzea and Igapó, cover an area of more than 97 000 km2. A key factor for their function diversity is annual flooding. Increasing air temperature higher precipitation variability caused by climate change are expected to shift flooding regime during this century, thereby impact floodplain ecosystems, biodiversity riverine ecosystem services. To assess effects on regime, we use Dynamic Global Vegetation Hydrology Model LPJmL, enhanced a scheme that...
Much of our knowledge about land use and ecosystem services in interrelated social-ecological systems is derived from place-based research. While local regional case studies provide valuable insights, it often unclear how relevant this research beyond the study areas. Drawing generalized conclusions practical solutions to management observations formulating hypotheses applicable other places world requires that we identify patterns are similar those represented by study. Here, utilize...
Irrigated rice croplands are among the world's most important agro-ecosystems. They provide food for more than 3.5 billion people and a range of other ecosystem services (ESS). However, sustainability agro-ecosystems is threatened by continuing climate land-use changes. To estimate their combined effects on bundle ESS, we applied vegetation hydrology model LPJmL to seven study areas in Philippines Vietnam. We quantified future changes provision four essential ESS (carbon storage, carbon...
Climate change and land-use are two major drivers of biome shifts causing habitat biodiversity loss. What is missing a continental-scale future projection the estimated relative impacts both on over course this century. Here, we provide such for biodiverse region Latin America under four socio-economic development scenarios. We find that across all scenarios 5-6% total area will undergo can be attributed to climate until 2099. The impact may overtake even an optimistic scenario, if expansion...
Abstract. A variety of modelling studies have suggested tree rooting depth as a key variable to explain evapotranspiration rates, productivity and the geographical distribution evergreen forests in tropical South America. However, none those acknowledged resource investment, timing physical constraints within competitive environment, undermining ecological realism their results. Here, we present an approach implementing strategies dynamic root growth into LPJmL4.0 (Lund-Potsdam-Jena managed...
Abstract The adoption of agri-environment practices (AEPs) is crucial for safeguarding the long-term sustainability ecosystem services within European agricultural landscapes. However, tailoring policies to unique characteristics farming systems a challenging task, often neglecting local farm parameters or requiring extensive survey data. Here, we develop simplified typology system archetypes (FSAs), using field-level data on farms’ economic size and specialisation derived from Integrated...

Abstract. Comparing model output and observed data is an important step for assessing performance quality of simulation results. However, such comparisons are often hampered by differences in spatial scales between local point observations large-scale simulations grid cells or pixels. In this study, we propose a generic approach pixel-to-point comparison provide statistical measures accounting the uncertainty resulting from landscape variability measurement errors ecosystem variables. The...
Abstract. Neglecting any atmospheric feedback to precipitation, deforestation in Amazon, i.e., replacement of trees by shallow rooted short vegetation, is expected decrease evapotranspiration (ET). Under energy-limited conditions, this process should lead higher soil moisture and a consequent increase river discharge. The magnitude sign the response ET depends both on land-cover change (LCC), climate CO2 concentration changes future. Using three regional LCC scenarios recently established...
Abstract. Tree water access via roots is crucial for forest functioning and therefore forests have developed a vast variety of rooting strategies across the globe. However, Dynamic Global Vegetation Models (DGVMs), which are increasingly used to simulate functioning, often condense this tree into biome-scale averages, potentially under- or overestimating response intra- inter-annual variability in precipitation. Here we present new approach implementing variable dynamic root growth LPJmL4.0...
Abstract. A key factor for the functioning and diversity of Amazonian rain forests is annual flooding. However, increasing air temperature higher precipitation variability, caused by climate change, are expected to shift flooding regime, thereby negatively impact floodplain ecosystems, their biodiversity riverine ecosystem services during this century. To assess effects changes on we use Dynamic Global Vegetation Hydrology Model LPJmL, enhanced a scheme that realistically simulates floodable...
Abstract. Any regular interaction of land and river during flooding affects carbon pools within the terrestrial system, riverine exported from system. In Amazon basin fluxes are considerably influenced by annual flooding, which terrigenous organic material is imported to river. The therefore represents an excellent example a tightly coupled terrestrial–riverine processes generation, conversion transport in such terrigenous–riverine system strongly interact climate-sensitive, yet their...
