Dynamics of the Red River Bed in the Hanoi Region

Biogeosystem Technique. 2021. 8(2): 70-78.
DOI: 10.13187/bgt.2021.2.70CrossRef

Abstract:
The article substantiates the need to study the fluctuations of the area of the Red riverbed in the area of the city of Hanoi in certain historical periods. A methodology proposed for studying the river, including methods of remote sensing of the Earth (remote sensing) and Geographic Information System (GIS).During each historical period, the Red Riverbed changes in the direction of a gradual balance of bends, erosion of the banks and growth between the two banks. The influence of climate change on spatial changes in the riverbed analyzed using a superimposed map and ceilings. Explosive fluctuations in the area of the riverbed detected during periods of peak floods and greatest droughts. The results of the research formed the basis for creating a spatial security corridor and planning operational and environmental solutions on both banks of the river.

Nano-Priming Technology for Sustainable Agriculture

Biogeosystem Technique. 2021. 8(2): 79-92.
DOI: 10.13187/bgt.2021.2.79CrossRef

Abstract:
Climate change affected crop growth and development which reduced crop production. Decreasing crop production can create food security-related problems. Nanotechnology is a new era of technology for the solution of climate change-related problems in agriculture we can say the "NanoTech-Agril" era that helps the farmer to produce a larger number of crops without any problem related to climate change problems like salinity, drought, flood etc. Nanoparticle-based seed priming can enhance the seed metabolism and signalling pathways, that not only enhanced seed germination but also help in the establishment of plants for the entire lifecycle. Nano-seed priming also enhanced the metabolic, biochemical, antioxidant and phytohormone pathways resulting in the promotion of abiotic and biotic stresses that cut off the need for pesticides and fertilizers. The present review provides an overview of the nanoparticle application for sustainable agriculture.

Geoecological Aspects of Migration of Heavy Metals in Environment and Antioxidant Status of Plants

Biogeosystem Technique. 2021. 8(2): 93-101.
DOI: 10.13187/bgt.2021.2.93CrossRef

Abstract:
The geoecological assessment of the multi-component impact of technogenic pollution of natural soil zones is necessary for the comprehensive evaluation of environmental investigation of the impact of climate change on biota. The aim of a study was to use a combined assessment method of pollution in a chain soil-plant based on the values of a number of biogeochemical coefficients in the chain of soil-plant (1), and bioaccumulation of plants to assess the level of pollution for some HMs in the different regions of Armenia (2). The object of the study was the Armenian species of Zea mays L. and samples of soil near the river's coast. To quantitatively determine the indicators of the antioxidant system, the fifth leaf of Zea mays L. was used to determine the concentration of malondialdehyde in the presence of 2-thiobarbituric acid; the concentration of Ferric reducing the ability of plasma; concentration of polyphenols and flavonoids. The potential biochemical mobility of HMs from soil to plant (Km), index of pollution (Ipol), and the value of the span of pollution (SP) were calculated in samples of soils. The excess concentration changes the Km coefficient for Mo, Zn, and Cr for the studied samples of maize from different soil and climatic conditions are shown. It was found that, depending on the soil conditions, in almost all studied territories, Mo and Zn are strong concentrators, and the remaining HMs are deconcentrators in the range from strong (0.04-0.0025) to weak (0.4-0.25). We are inclined to assert that the antioxidant system is that sensitive component of the plant organism, which primarily reacts to changes in the environment caused by uncontrolled changes in micro and macro elements in biota.
