Prospects for achieving the Intended Nationally Determined Contribution of Kazakhstan in the framework of the Paris climate convention was assessed through projections of greenhouse gases (GHG) emissions of 31 large energy enterprises by 2030. The total CO2 emissions of these enterprises reach 86,9 million tons or 26,5 % of the country’s GHG emissions. For projection of the GHG emissions of the selected power plants three scenarios - “business as usual” (trend), “moderate modernization” and “full modernization” - were designed. “The unconditional target” would remain unachievable in the “business as usual” and even “moderate modernization” scenarios. However, the scenario of “full modernization” allows reaching “the unconditional target” with a good reserve. Moreover, this scenario allows reaching “the conditional target”. Our assessment of potential for reduction of the GHG emissions shows that Kazakhstan’s commitments in the Paris climate convention are very responsible. To meet these commitments technological modernization of the entire industrial sector of the country would be required. It could be achieved only by full mobilization of material and financial resources.

Gastropoda is a large class in coastal waters in Central Vietnam. The interaction between microorganisms and Gastropoda mainly consists of symbiotic and parasitic relationships. In this study, biodiversity of microbial communities on some species of Gastropoda is evaluated, thereby predicting their interaction. From 12 samples of Gastropoda including 3 species: Trochus maculatus , Cypraea eglantica , Chicoreus bruneus , 101 microorganism strains including 79 bacterial strains (78.2%), 18 yeast strains (17.8%) and 4 actinomycetes strains (4.0%) were isolated. There were 15 strains (including 8 yeast strains, 5 bacterial strains and 2 actinomycetes strains) selected to identify based on sequence analysis of the D1/D2 region (yeast) and 16S rRNA gene (bacteria and actinomycetes). Based on the identification results, it is possible to predict the nutritional relationship between microorganisms and species of Gastropoda.

The article presents the chemical elements with the highest content of gross and mobile forms in the soil solution of ground near the aerodrome area of the Moscow Domodedovo Airport. The most important types of plant-hyperaccumulants, which can stabilize the geochemical situation around airport are considered in the paper. The types of plants which can sorb in shortest time some metals-pollutants are brought together in tables. Thanks to the research, the features of pollutants of the soils near the aviation hub are defined. Part of the study had become the development recommendations on reduction of environmental burden on adjacent to the airport lands through the creation of phytobuffers.

The purpose of this scientific and practical research is to increase efficiency of the use of biorepellent (birds of prey) while ensuring the ornithological safety of facilities for the municipal solid waste recycling and disposal. Various forms of gregarious protective behavior of synanthropic birds (Corvidae, Laridae) are considered. A new form of protective behavior has been revealed in the Corvidae family.

Even though Nigeria is recognized for her rich vegetation and tropical weather and blessed with surplus water resources, the country still faces challenges on getting clean water supply around the country and mostly depend on alternative water supply like well, borehole and river. These alternative water supply systems are not efficient and viable enough for water supply systems especially in a country with large population. The country is characterized by irregular water supply and water management laws are also weak and mostly not in conformity with today's standard and needs. Proper management and conservation of the water supply services and resource has not given adequate attention by the government. It is, therefore, important to identify such factor that inhibits the implementation of water regulations and proffer a solution to these. In a bid to provide an understanding of the effect of implementing and enforcing stringent water regulation and providing adequate water supply, we compare forecasted population with investment capital expenditure (CAPEX) for water supply by Millennium Development Goal (MDG+) targets. The result shows that in year to come, the country will significantly benefit from investing and providing regular water supply through employment availability and revenue generated through utility water bills, spending less on epidemic of water-borne diseases thereby improving the lives and health of its citizen.
