In the context of climate change, drought has been recognised as one most severe threats for agricultural production since absence water is limiting factors growth plants. this study, a regional system soil moisture prediction based on ERA5 reanalysis dataset, an open-source meteorological dataset issued by Copernicus Climate Change Service, was developed. It consisted relevant parameters Serbia, during period 2011–2020. Daily values maximum and minimum air temperature, precipitation vapour...

Yield prediction models can be divided between data-driven and process-based (crop growth models). The first category contains many different types of with parameters learned from the data themselves where domain knowledge is only used to select predictors engineer features. In second category, are based upon biophysical principles, whose structure derived primarily knowledge. Here we investigate if integration two approaches beneficial as it allows overcome limitations taken individually -...

A broad variety of research indicates that climate change has intensified and extended meteorological droughts across parts Europe, with southern European regions experiencing particularly severe impacts (IPCC, 2012). The majority SEE countries are an increase in drought severity frequency according to a plethora research. most commonly used indicators by regional experts indexes such as SPI, SPEI, PDSI, well more specific parameters like the maximum seasonal dry spell (DS), SGI, discharge...

Information on the harvest date of crops can help with logistics management in agricultural industry, planning machinery operations and also yield prediction modelling. In this study, determination dates for different were performed by applying machine learning techniques C-band synthetic aperture radar (SAR) data. Ground truth data provided Vojvodina region (Serbia), an area intensive production, considering winter wheat, maize soybean fields exact dates, period 2017–2020, including 592...

This is the first time that atmospheric concentrations of individual pollen types have been recorded by an automatic sampler with 1-hour and sub-hourly resolution (i.e. 1-minute 1-second data). The data were collected traditional Hirst type methods state-of art Rapid-E real-time bioaerosol detector. Airborne from 7 taxa, i.e. Acer negundo, Ambrosia, Broussonetia papyrifera, Cupressales (Taxaceae Cupressaceae families), Platanus, Salix Ulmus, during 2019 season in Novi Sad, Serbia. Pollen...

Abstract We propose novel metrics based on the Kolmogorov complexity for use in complex system behavior studies and time series analysis. consider origins of discuss its physical meaning. To get better insights into nature systems analysis we introduce three measures complexity: (i) spectrum, (ii) spectrum highest value (iii) overall complexity. The characteristics these have been tested using a generalized logistic equation. Finally, proposed applied to different originating from: model...

Considerable amounts of starch granules can be present in the atmosphere from both natural and anthropogenic sources. The aim this study is to investigate variability potential origin ambient air recorded at six cities situated a region with dominantly agricultural land use. This achieved by using combination laser spectroscopy bioaerosol measurements 1 min temporal resolution, traditional volumetric Hirst type sampling atmospheric modelling. analysis wind roses identified sources airborne...

Some issues which are relevant for the recent state in climate modeling have been considered. A detailed overview of literature related to this subject is given. The concept climate, as a complex system, seen through Gödel’s theorem and Rosen’s definition complexity predictability discussed. Occurrence chaos computing environmental interface temperature from energy balance equation given difference form pointed out. coupled system equations, often used models, was analyzed. It shown that...

The drought in Serbia the summer of 2017 heavily affected agricultural production, decreasing yields maize, sunflower, soybean, and sugar beet. Monitoring moisture levels crops can provide timely information about potential risk within a growing season, thus helping to create an early warning system for various stakeholders. purpose this study was quantify level stress during consequences that it have on yields. For that, maize sunflower yield data provided by company were used at specific...

Motivated by the One Health paradigm, we found expected changes in temperature and UV radiation (UVR) to be a common trigger for enhancing risk that viruses, vectors, diseases pose human animal health. We compared data from mosquito field collections medical studies with regional climate model projections examine impact of change on spreading one malaria vector, circulation West Nile virus (WNV), incidence melanoma. analysed obtained ten selected years standardised vector sampling 219 unique...

Turbulence is often expressed in terms of either irregular or random fluid flows, without quantification. In this paper, a methodology to evaluate the randomness turbulence using measures based on Kolmogorov complexity (KC) proposed. This applied experimental data from turbulent flow developing laboratory channel with canopy three different densities. The even compared traditional approach classical statistics.

Chemical control O. remains main strategy conventional production. The key to successfully achieving a high efficiency insecticides determining appropriate moment application, including exact time insect’s life cycle when it vulnerable. In this study, monitoring data on flight dynamics ECB...
