Russia is a white spot on the tea bag index map: an approach to extend the network of global soil decomposition monitoring

The tea bag approach (http://www.teatime4science.org/about/the-project/) for measurement of microbial decomposition of soil organic matter has been applied for mountain, coastal, forest and arctic ecosystems, while for urban ecosystems located in various biomes such experience is not widely distributed. In Russia there are few amount of sites for which was provided the soil organic matter decomposition assessment by tea bag approach.

Smart Urban Nature team together with colleagues from the Kola Science Centre RAS, Institute of Geography RAS, Southern Federal University, Institute of Physicochemical and Biological Problems of Soil Science, RAS, the Central Chernozem Reserve, have decided to extend of the global map of the tea bag index and organized monitoring of the microbial activity of various soils in the European Russia with financial support of RSF No. 19 -77-30012.

Drones to be detectors of heavy metals in the soil

SUN Lab scientists have created maps of distribution of concentrations of heavy metals nickel and copper in the upper soil horizon. This was made possible through data obtained by unmanned aerial vehicles. The essence of the method is to search for statistically significant relationships between point data on the concentrations of hazardous elements in the upper horizon and the parameters of the relief and soils. The approach has been successful in a technogenic wasteland area on the Kola Peninsula, and as expected, in the future, the technology will help scientists more quickly predict soil pollution in vast and remote areas. The results of the study, supported by a grant from the Russian Science Foundation, were published in the journal Land Degradation & Development.

SUN Lab presented the results of the third year of the SUN project

SUN Lab presented the results of the third year of the project “Smart technologies to monitor, model and evaluate ecosystem services provided by urban green infrastructure and soils to support decision making in sustainable city development under global changes”, supported by a Russian Science Foundation (RSF).

Research in the third year of the project was focused on 3 main objectives:

  1. monitoring of ecosystem services of urban green infrastructure based on the Smart Urban Nature network;
  2. interpretation of monitoring data for ecosystem services for various target groups and practical tasks;
  3. application of the results of monitoring and modeling ecosystem services to support decision-making in the field of sustainable development of the urban environment.

The Soil Basis of Smart and Sustainable Cities: How Scientists from SUN Lab expand knowledge about the functions of urban soils

It is a well-known fact that soil is the main component of a terrestrial ecosystem, the balanced functioning of which largely depends on the soil microbiome. Today, in the urban environment, there is an unprecedented anthropogenic impact on the soil, its microbiome and the ecosystem as a whole, which can lead to disruption of their functioning. Researchers from all countries are trying to develop knowledge about the peculiarities of the functioning of the soil microbiome in urban conditions, in particular by studying its various microbial indicators. However, there is no answer to the question of which microbial indicators can most informatively reflect the functioning of urban soils and be useful in planning and improving urban areas.

Studying urban soils and green infrastructure: the fifth 3MUGIS-2021 summer school took place online

From July 26 to August 2, 2021, the 5th International Summer School 3MUGIS (Monitoring, Modeling and Managing Urban Soils and Green Infrastructure) was held within the Department of Landscape Design and Sustainable Ecosystems Smart Urban Nature Laboratory of the RUDN University. The school was organized with the support of the Russian Science Foundation and under the umbrella of the International Union of Soil Scientists, RUDN University and the Institute of Urban Soils of New York in collaboration with universities, scientific organizations and research groups from around the world. The partners of the school were Brooklyn College (USA), Kola Science Center of the Russian Academy of Sciences, Southern Federal University and many others. Importantly, all the organizers and partners of 3MUGIS are united by the desire to exchange knowledge, ideas and experience at the international level.

SUN researchers examined how urban development has increased soil carbon stocks

The team of scientists of SUN Lab (RUDN University) in collaboration with scholars from Moscow State University and Southern Federal University got their article “Projecting the urbanization effect on soil organic carbon stocks in polar and steppe areas of European Russia by remote sensing” published in Geoderma, the global journal of Soil Science. The research was supported by a grant from the Russian Science Foundation (RSF).

With the help of satellite images and archival data, our scholars have established the mechanisms of the impact of urbanization on the state of soils in the forest-tundra and steppe zones. Previously, it was commonly believed that covering the soil with asphalt, concrete and other impermeable materials leads to an overall decrease in carbon stocks in soils of urban areas. But it was revealed that in Murmansk and Rostov-on-Don, the total carbon stocks in a meter layer of the earth have significantly increased due to the development of urban green infrastructure.

SUN Lab research team got a new scientific article released

In May 2021, SUN lab team’s scientific merit fund was replenished with an article “Gypsum soil amendment in metal-polluted soils — an added environmental hazard” which was published in the Chemosphere journal (SJR Q1). The authors team was represented by the Head of Agrarian Technological Institute (RUDN University) E.A. Dovletyarova, associate researchers Brykova R.A. and Losev A.I., postgraduate student Dubrovina T.A. in collaboration with Neaman A.A., professor of Institute of Agrarian Engineering at Southern University of Chili.

The biological component of microparticles in big cities: SUN Lab is developing research on improving air quality in urban conditions

Airborne fine dust particles (FD) are recognized as one of the most harmful pollutants to human health. The size of fine dust determines their ability to penetrate the human body, and particles less than 10 microns in size are recognized as the most dangerous. At the same time, the causes of FD toxicity are still insufficiently studied. For example, the relationship between mortality from COVID-19 and the concentration of FD in the air was shown. However, it is still not clear whether fine dust is a direct vector carrier of the virus or only exacerbates the susceptibility of the human body to the virus.
