The Siberian Arctic is warming fast: permafrost is thawing, river chemistry is changing, and coastal ecosystems are affected. We want to understand changes to the Lena River, a major Arctic river flowing to the Arctic Ocean, by collecting 4.5 years of detailed water data, including temperature and carbon and nutrient contents. This dataset records current conditions and helps us to detect future changes. Explore it at https://doi.org/10.1594/PANGAEA.913197 and https://lena-monitoring.awi.de/.

Permafrost ecosystems are limited in nutrients for vegetation development and constrain the biological activity to the active layer. Upon Arctic warming, permafrost degradation exposes organic and mineral soil material that may directly influence the capacity of the soil to retain key nutrients for vegetation growth and development. Here, we demonstrate that the average total exchangeable nutrient density (Ca, K, Mg, and Na) is more than 2 times higher in the permafrost than in the active layer.

Arctic warming and permafrost degradation largely affect tundra vegetation. Wetter lowlands show an increase in sedges, whereas drier uplands favor shrub expansion. Here, we demonstrate that the difference in the foliar elemental composition of typical tundra vegetation species controls the change in local foliar elemental stock and potential mineral element cycling through litter production upon a shift in tundra vegetation.

The drivers of high accumulation of single-cell siliceous algae (diatoms) in a high-latitude lake have not been fully characterized before. We studied silicon cycling of the lake through water, radon, silicon, and stable silicon isotope balances. Results showed that groundwater brings 3 times more water and dissolved silica than the stream inlet. We demonstrate that groundwater discharge and low sediment deposition have driven the high diatom accumulation in the studied lake in the past century.

We study the appearance in 2008–2014 and disappearance after 2015 of a phytoplankton spring-bloom in the brackish region in the Scheldt estuary. To this end, we analyze long-term in situ observations covering the full estuary and apply a model approach to determine which of the changed conditions may explain the observed change in phytoplankton. Our results suggest that insight into the zooplankton dynamics is essential to understand the phytoplankton dynamics in the Scheldt estuary.

With global warming, ice-rich permafrost soils expose organic carbon to microbial degradation and unlock mineral elements as well. Interactions between mineral elements and organic carbon may enhance or mitigate microbial degradation. Here, we provide a large scale ice-rich permafrost mineral concentrations assessment and estimates of mineral element stocks in those deposits. Si is the most abundant mineral element and Fe and Al are present in the same order of magnitude as organic carbon.

Weathering is a major control on atmospheric CO2 at geologic timescales. Enhancement of this process can be used to actively remove CO2 from the atmosphere. Field results are still scarce and with this experiment we try to add some near-natural insights into dissolution processes. Results show CO2 sequestration potentials but also highlight the strong variability of outcomes that can be expected in natural environments. Such experiments are of the utmost importance to identify key processes.

Within a confined estuary, a large wetland can play an important role in storm surge mitigation. By use of a numerical model the effects of different wetland sizes, wetland elevations and wetland locations along the estuary on storm surge attenuation along the estuary were investigated. With this paper we aim to contribute towards a better understanding and wider implementation of ecosystem-based adaptation to increasing estuarine flood risks associated with storms.

Biogenic silica (BSi) is used as a proxy by soil scientists to identify biological effects on the Si cycle and by palaeoecologists to study environmental changes. We show the presence of tephra constituents can make measurements erroneous at low BSi concentrations, with repercussions for soil and palaeoecological studies. However, we also show that glass shards do not produce an identical dissolution signal to that of BSi, meaning they can be distinguished with appropriate experimental setups.

Short summary
We link the mineralogy of soils affected by erosion and deposition to the distribution of soil carbon fractions, their turnover and microbial activity. We show that the weathering status of soils and their history are controlling the stabilization of carbon with minerals. After burial, aggregated C is preserved more efficiently while non-aggregated C can be released and younger C re-sequestered more easily. Weathering changes the effectiveness of stabilization mechanism limiting this C sink.

Soil erodibility (K) is one of the key factors of soil erosion. Selecting the optimal estimation method of soil erodibility is critical to estimate the amount of soil erosion, and provide the base for sustainable land management. This research took the Loess Plateau of China as a case study, estimated soil erodibility factor with different methods, selected the best texture-based method to estimate K, and aimed to understand the indirect environmental factors of soil erodibility.

Physical aspects and knowledge of soil erosion in six rural communities in Chiapas, Mexico, were assessed. Average erosion rates estimated using the RUSLE model ranged from 200 to 1200 ha−1 yr−1. Most erosion rates were relatively high due to steep slopes, sandy soils, and bare land cover. The results of a knowledge, attitudes, and practices (KAP) survey showed that some communities with high erosion rates also had less knowledge of and more negative attitudes towards soil erosion management.

The speed of land use changes is much higher than in the past, which led to many changes in the environment and ecological processes. These changes cause some changes in the climate, the amount of pollution and biodiversity. Monitoring and modeling historical situation of the region can be used to anticipate the negative effects of these changes in order to protect resources. Agriculture class will be faced with a huge reduction of carbon sequestration because of expansion of residential areas.

The soil texture representation with the standard textural fraction triplet sand–silt–clay is commonly used to estimate soil properties. The objective of this work was to test the hypothesis that other fraction sizes in the triplets may provide a better representation of soil texture for the reconstruction of the particle size distribution and for estimating some soil properties with soil texture as a predictor. The results supported the hypothesis.

The severity of land degradation was assessed by analysing the physico-chemical parameters and correlating with satellite data in the Bathinda district, Punjab. Most of the soil samples were slightly or moderately saline, while a few were calcareous and alkaline. Comparing the satellite datasets of 2000 and 2014 revealed an increase in settlements and a decrease in barren area. The study can be useful for soil and environmental scientists and planning agencies for restoration of degraded lands.

Andic soils have unique morphological, physical and chemical properties that induce both considerable soil fertility and great vulnerability to land degradation. Here we attempt to show that soils rich in poorly crystalline clay minerals have an utmost ecological importance.
Our results are hoped to be a starting point for better understanding the ecological importance of andic soils and also possibly to better consider pedological information in carbon balance calculations.

The influences of land-use conversion on soil properties and bacterial communities were assessed. Diversity was detected in four distinct land-use systems through high-throughput sequencing. Land-use changes affected soil properties and bacterial community structures. The microbial dominant taxa were unchanged, but their relative abundances were significantly different, indicating that the effects of land-use conversion on bacterial communities were more quantitative than qualitative.

Cocoa agroecosystems are a major land use type in West Africa, reportedly associated with the problem of soil degradation. This study developed a composite soil degradation assessment index (CSDI) for determining the degradation status of cocoa soils under smallholder farming systems in southwestern Nigeria. The newly developed index can show early warning signs of soil degradation, which can help farmers and extension officers to implement rehabilitation practices on degraded cocoa soils.

This paper describes methodological experience and provides data references for international counterparts to study soil erosion in karst landform areas. The lithological and desertification factors introduced in the soil erosion model accurately reflect and predict soil erosion conditions and spatial distribution characteristics in karst areas. Future studies on soil erosion in karst areas should include underground loss in the calculation scope.

The aim of this study is to relate the potential of land for a particular use in a given region with the actual land use. To this aim, the impact of several land cover flows related to urban development on soils with good, average, and poor production potentials were assessed and mapped. Thus, the amount and quality (potential for agricultural production) of agricultural land lost between the years 2000 and 2006 and the regions with major impact (hot spots) in Europe were identified.

First, we report the following discovery: T values are spatially heterogeneous, and a minimum of three criteria should be considered instead of only a single criterion in karst areas. In fact, our findings disprove the old “one region, one T value” concept.
Second, we proposed a new viewpoint: in karst regions, a large soil erosion modulus does not correspond to severe soil erosion. Although T value can reflect soil sensitivity, this value cannot indicate soil erosion risk.

Two fire-affected soils have been studied using micromorphological methods. The objective of the paper is to assess and compare fire effects on the micropedological organisation of soils in a forest-steppe zone of central Russia. The burnt soils differ from the control on a macromorphological level only in the upper part of the profile where the litter is transformed to ash identified as a dim grey organomineral mixture. Processes of soil erosion are clearly manifested 1 year after the fire.

Soil is a sphere of the earth system with a special structure and function. From the point of view of the earth system, soil science should not only study the soil material but also change towards the relationship between the soil and the
earth system, which has a profound impact on the human living environment and global change research. The results show the relationship between soil Atterberg limits and the occurrence mechanism of collapsing gullies, which can be used as a reference.

Soil and water losses in agriculture are a major environmental problem on the Loess Plateau, China. This study investigated the effects of wheat stubble on soil erosion in laboratory plots under simulated rainfall. These results show that the traditional plow may induce more serious soil and water losses compared to wheat stubble cover. Wheat stubble cover delayed runoff generation time, decreased the runoff and sediment loss, and increased rainwater infiltration into the soil.

Organic matter addition is an efficient way of reducing the effects of field traffic. The depth-dependent (0–10 and 10–20 cm) changes in some physical soil traits such as penetration resistance, bulk density, and porosity as a function of tractor passes and organic matter addition to clay soil.
The enhancing effects of treatments on the investigated parameters were C>GM>FYM. The increase in tillage lines made the soil properties worse and corresponded with the type of organic matter.

Al toxicity to plants and soil infertility in acidic soils are the main limiting factors for crop growth. To establish which acid soils need to be ameliorated for plant growth, the parameters of critical soil pH and soil Al concentration must be determined. The critical soil pH and exchangeable aluminium of two Ultisols for wheat and canola production were determined in this study. The results obtained will provide useful references for the utilization and management of acid soils.

This is an interesting piece of work and makes a nice contribution to the knowledge on how aboveground vegetation can control belowground soil properties through functional traits and functional diversity. Functional traits are the center of recent attempts to unify key ecological theories on species coexistence and assembly in communities. The results presented are valuable for understanding the relationship between species traits, functional diversity, and soil properties.

This study was conducted to estimate the rate of soil erosion and to evaluate the existing SWC strategies in the Koga watershed. A mixed approach of field investigation and an integrated RUSLE model modified for Ethiopian highlands is being adopted for soil erosion assessment. Most of the existing SWC structures fail to meet the standard due to deficient construction and management of SWC structures. The soil erosion rate is by far higher than the tolerable soil loss rate.

The soil properties of Batumi delta, an important area for agricultural production and biodiversity in the southwest of Georgia, have not been studied yet. In order to provide scientific data, soil samples were taken from different points of delta and their basic characteristics were determined. At the end of the study, the results indicated that the soil properties were affected by the formation time and land use, and the relations between the soil properties varied depending on these factors.

The development of alternative low-cost and low-environmental-impact revegetation methods is necessary for the effective management of Mediterranean forest environments. This research assessed the effects of five types of soil amendment on the success of afforestation processes. In terms of land management, the study shows that the addition of mulch or hydroabsorbent polymer can reduce transplanting stress and improve the success of afforestation programs.

In this study the features of pedogenic evolution of four soil profiles formed in topographically different positions of the southwestern–northeastern direction were investigated. The results of the study showed a strong relationship between the topography and some of the soil’s morphological, mineralogical, physical and chemical characteristics. Soil depth and physical soil features such as texture, structure and bulk density were found to improve downwards within the toposequence.

Climate and soil surface conditions influence the erosive capacity of the wind, causing loss of soil productivity. Wind erosion leads soil drying and its loss of nutrients, and this in turn is conditioned by soil surface compaction. The impact of management on most of soil properties and on its wind erodibility determines agricultural productivity and sustainability. We used a new wind tunnel to evaluate all these acts.

Short summary
We studied the effect of land conversion and erosion intensity on the biogenic silica (BSi) pools in a subtropical soil in the south of Brazil. Our study shows that deforestation will rapidly (< 50 years) deplete (10–53 %) the biogenic alkaline extractable Si (AlkExSi) pool in soils. Higher erosion in steeply sloped sites implies increased deposition of biogenic Si in deposition zones near the bottom of the slope, where rapid burial can cause removal of BSi from biologically active zones.
