The concept of sustainable development environmental aspects and project approach

This article analyzes the environmental aspects of sustainable regional and macroeconomic development, as well as the impact of environmental factors and national environmental projects. The essence of the concept of sustainable development of economic entities in a broad sense is to ensure stable growth of indicators in the environmental, social and economic spheres in the long term. Based on the analysis of the list of indicators of sustainable development, the increasing role of the environmental component is shown. We have identified particularly acute environmental problems that hinder effective sustainable development both at the micro-level (of the organization) and at the macro-level in the whole country and the global community. Based on the calculation of the nature protection, socio-ecological and industrial-ecological indices, the consolidated environmental rating and the place of the Kirov region is determined in it. The analysis of the results of research and the opinions of the World Economic Forum experts on the problems of global threats showed the timeliness and relevance of the national project “Ecology” being implemented in Russia, as well as measures of environmental support and planned environmental projects in the Kirov region. The implementation of the planned measures will activate the catalysts of sustainable development and reduce the risks of negative impact on the environment.

Reforestation in the Kirov region as an indicator of regional environmental risks

et al. 2020

View full text Add to dashboard Cite

This article analyzes approaches to the selection of indicators of regional environmental risks, as well as the impact of risks on reforestation in a particular region. Indicators that characterize the main trends in the forestry industry in Russia were analyzed using monographic, economic, mathematical, and statistical methods. Factors that promote and hinder effective reforestation in the whole country and in the Kirov region are identified. The authors draw a conclusion about the degree of influence of various factors on reforestation in the region. The consolidated environmental rating of the region was determined based on the calculation of the nature protection, socio-ecological and industrial-ecological indices. A comparative analysis of official statistics and satellite monitoring results revealed significant differences in the results of estimating the area of lost forests. Promising areas for reforestation specified, using methods of Abstract-logical assertions and expert assessments, as well as indicators of the regional project “Conservation of forests of the Kirov region»: provision of state institutions with specialized forestry machinery and equipment, training, increasing the area of artificial reforestation, formation of a reserve of forest seeds, attraction of investments, development of the foundation of logging roads. The implementation of the planned measures will make it possible to use the existing forest resources of the region more effectively, preserving and multiplying this invaluable resource.

“…To theoretically analyze the formation of the light field transverse structures under the FWC in the nonlinear interferometer, we will use the system of wave equations for the light field complex amplitudes, obtained in [7] for the two-level model of the resonance medium (1) where A 0 = 1 + 2 ( I 1 + I 2 ) + ( + ); E 10 , and E 20 are the amplitudes of the light waves at the entrance of the interferometer, E 1 and E 2 are the amplitudes at the exit of the interferometer, C = k 0 ( ω ) L / T is the cooperative parameter, k 0 L is the optical thickness of the nonlinear layer, T is the transmittance of the resonator's mirrors, ∆ 0 = (4 π n 0 L / λ -2 m π )/ T is the initial detuning of the interferometer from the resonance ( m is an integer), β = λ L /2 π T is the diffraction parameter, = α 0 L /2 π T is the normalized value of the angle of incidence α 0 of the light beams, t R = 2 L / v T is the transient time of the field in the resonator, = a + i α = ( + )/ v p 21 is the --------, - complex parameter of nonlinearity for the two-level resonance medium [8], = Θ ij (ω) + iB ij (ω), the coefficients Θ ij (ω) are related by the Kramers-Kronig dispersion relations with the Einstein coefficients B ij (ω) for stimulated transitions, v is the speed of light in the medium, and p 21 is the total probability of the spontaneous and nonradiative transitions. The light wave intensity is normalized to the coefficient α = (B 12 + B 21 )/vp 21 , which determines the saturation intensity of the resonance medium (I sat = α -1 ).…”

Specific features of the light-beam transverse structure transformation in the process of four-wave coupling in the Fabry-Perot interferometer with a resonant nonlinearity under conditions of bifurcation of the symmetry breaking and optical bistability are analyzed. The asymmetric regimes of the interaction, characterized by a difference both in the integrated transmission functions of the nonlinear interferometer for two light beams with equal intensities and in the spatial intensity distribution at the exit of the interferometer, are considered.
