The study shows results of research on reed productivity and on factors influencing this productivity. The research was performed during winter period from 2010 until 2012 in 23 natural and artificial water bodies of Latvia. The author of this study analyzed indexes of reed growth productivity and found regularities that statistically significantly (p less then 0,05) explain changes of reed productivity in water bodies depending on individual reed growing conditions in each water body. It is established that the productivity of reed growth depends on the amount of nutrients in the water of water body and that this productivity rises if the total concentration of nitrogen and phosphorus in the water is increased. The reed productivity is lower in clearer water. This parameter may be used in order to evaluate the amount of extractable biomass. The coherence is characterized by statistically significant (p less then 0,05) regression equation.

Abstract. Emissions from flooded land represent a direct source of anthropogenic greenhouse gas (GHG) emissions. Methane emissions from large, artificial water bodies have previously been considered, with numerous studies assessing emission rates and relatively simple procedures available to determine their surface area and generate upscaled emissions estimates. In contrast, the role of small artificial water bodies (ponds) is very poorly quantified, and estimation of emissions is constrained both by a lack of data on their spatial extent and a scarcity of direct flux measurements. In this study, we quantified the total surface area of water bodies < 105 m2 across Queensland, Australia, and emission rates from a variety of water body types and size classes. We found that the omission of small ponds from current official land use data has led to an underestimate of total flooded land area by 24 %, of small artificial water body surface area by 57 % and of the total number of artificial water bodies by 1 order of magnitude. All studied ponds were significant hotspots of methane production, dominated by ebullition (bubble) emissions. Two scaling approaches were developed with one based on pond primary use (stock watering, irrigation and urban lakes) and the other using size class. Both approaches indicated that ponds in Queensland alone emit over 1.6 Mt CO2 eq. yr−1, equivalent to 10 % of the state's entire land use, land use change and forestry sector emissions. With limited data from other regions suggesting similarly large numbers of ponds, high emissions per unit area and under-reporting of spatial extent, we conclude that small artificial water bodies may be a globally important missing source of anthropogenic greenhouse gas emissions.

The article is dedicated to the economic and legal aspects of environmental protection when using artificial water bodies. It was proved that to improve the efficiency of administrative responsibility for environmental crimes, the size of compensations and penalties should exceed the cost of actions of environmental protection. This will encourage the entities using artificial water bodies to provide advantages to the measures of environmental protection when using artificial water bodies formed within the limits of private land lots. It was offered to distinguish the legally valid and illegal damage to the environment. It was determined that the payment of compensation for the damage to the environment on the base of the special permission of the authorities was not considered a civil and legal liability. The payment of such compensation shall be considered a term for the legal use of the artificial water body by the methods that can be the reason for the damage to the environment.

Artificial Water

A brief review of the ecological state of artificial water bodies is presented on the example of the Voronezh and Matyr reservoirs located in the basin of the river. Voronezh. Ecological-geochemical interrelation of water areas of reservoirs and adjacent territories with anthropogenic sources of pollution located on them is shown. The basis of the research is the bioindication method for the communities of phytoplankton and microphytobenthos. Changes in the sanitary and biological quality of the waters have been studied in the reservoirs, which are related, in particular, to the effect of anomalously high summer air temperatures in 2010–2012 and in subsequent years, and for the Matyr reservoir against this background, an estimate of the effectiveness of the use of algobiotechnology is given.
