The issue of spatial development of post-industrial facilities and areas is currently one of the most important challenges of planning urban development. The renewal and revitalisation of such areas is part of contemporary trends involving optimal and sustainable development of urbanised areas in order to create a compact city, i.e. one efficiently using its spatial resources. The implementation of revitalisation projects is a complex and expensive process which often requires remediation or reclamation, and consi...

The agriculture is a sector where the impact of climate change leads to high risk and vulnerability in farmers' activities. The negative consequences are reflected in the direction of changes in agricultural land, decrease in productivity, soil erosion, salinization, deterioration of the conditions for raising animals and others. Tackling such problems is a challenge for farmers trying to balance the need to produce enough food for the population and, on the other, to mitigate the negative effects of climate chang...

Nowadays a major issue in managing the industrialized/logistic zones is represented by the environment protection. Circular economy or industrial ecology can be a sustainable model. The challenge for the economic actors of the Danube is the promotion of an Eco-friendly mode of transportation. The port administration and port operators should find solutions to implement an industrial ecology regime. Adapting an Eco-innovative solution should contribute on the number of the additional partners and clients. This cont...

The negative phenomenon of suburbanisation has been observed around the globe for many years. One of the methods of counteracting the process is directing the city?s development inward, improving the urban planning parameters, and using areas potentially attractive in terms of location but in need of new management. They are among others post-industrial areas, frequently characterised by a considerable degree of degradation (brownfields). The objective of the article is the determination of the potential of degrad...

The agri-environmental policy of the CAP is not new to the EU. It has been developing for over twenty-five years, as agriculture is the sector directly dependent on abiotic and biotic environmental factors. On the eve of the new programming period (2021-2027), challenges in relation to the environment, climate and sustainable agriculture are increasing. In the context of deepening environmental changes, the risks to agriculture are limited to: changes in agricultural land; reduction of agricultural productivity; r...

Mathematical modeling of river flow formation processes is the basic research and engineering tool for modern hydrology. Despite a number of undoubted successes in modeling and a fairly wide introduction of models into practice, a number of problems remain that point to the fundamental difficulties of traditional approaches to the problem. The most important among such tasks are: assessment of the regime of extreme hydrological events, primarily floods; Use of hydrological models on unexplored basins; Perspective ...

Fodder yeasts are widely used in animal feeding as a source of protein with high amount of B vitamins. While plant protein is very poor in such amino acids like lysine, methionine, tryptophan, single cell protein contents all complex of essential amino acids. Studies have shown advantages and possibilities of using single cell protein in complex with plant base for animal feeding. Sunflower is being one of the most cultivated agriculture in Russian Federation. Deproteinized sunflower meal is a secondary product of...
