Water is a key component of our environment; it is a renewable, limited and vulnerable natural resource, which provides economic, social, and environmental well-being of the population. The most promising source of drinking water supply is groundwater usage. Drinking and industrial groundwater is one of the most important components of the groundwater mineral resource base in the Russian Federation. Modern system of groundwater extraction management and state regulation is currently imperfect and has definite disadvantages, among them – lack of control over natural resources by the state, an old system of tax rates for the use of groundwater, commercialization stage of licensing, the budget deficit, which is passed on other spheres of the national economy. This article provides general information about the state of groundwater production and supply in Russia, negative trends of groundwater usage, some actions for the improvement in the system of groundwater’s fund management are suggested. The most important amendments of the law “About mineral resources” are overviewed, effects of these changes are revealed and recommendations for future groundwater extraction regulation are given.

Data from floristic publications, forest management records, comprehensive questionnaires and original field research were used to assess the silver fir resources in the Sudety Mts. Fir trees older than 50 years were recorded in over 2000 localities but the mean number of individuals per locality was only about 15. The generally low number of fir trees and their considerable dispersion are the major causes of the poor reproduction of the studied species in the Sudety Mts. In that region, silver fir should receive special treatment and, if possible, excluded from logging plans. Current and projected activities concerned with fir protection are described briefly.

Autorzy starają się odpowiedzieć na pytanie, w jakim stopniu duża inwestycja komunikacyjna, jaką jest budowa autostrady, wpływa na gospodarkę zasobami lokalnych złóż kopalin okruchowych, tj. czy i w jakim stopniu są one wykorzystywane oraz na ile ewentualna, wzmożona eksploatacja może wpłynąć na uszczuplenie ich rezerw zasobowych. Analizę przeprowadzono na jednym z ukończonych już odcinków autostrady A2 Września – Nowy Tomyśl.

The presented paper shows some results of the estimation of natural aggregate raw material indicated resources, mainly sands, in the area, where a motorway A2 sector (Września – Nowy Tomyśl) was built. The mineral reserve base and the output tendencies were shown. It was noted intensive increasing of the output from several local mineral deposits. In this time many new deposits were documented. The reserve base of natural aggregates seems to be partly renewed and changed, causing activity of geological research in the perspective areas. The main problem connected with intensive exploitation is to revitalize the post mining areas as quickly as possible.

In this article the authors present a simple method of determining the content of selected metal raw materials (Fe, Ni, Co) on the parent bodies of ordinary chondrites. Thanks to the use of planimeter for measuring, under microscope, polished slices of meteorites, it is possible to estimate quite accurately the proportion of these metals in the parent bodies of meteorites, i.e. on asteroids. When it comes to analysing a large number of polished slices, these results will be most likely comparable to much more expensive results of chemical tests conducted on meteorites. Based on the analysis of 16 thin polished sections and polished slices of 11 ordinary chondrites, the authors found out that the highest content of Fe, Ni and Co ore minerals, reaching 10,06% of the total volume, can be found in ordinary chondrites from group H. For ordinary chondrites from groups L and LL, it makes 3,86% and 3,93% of the volume respectively. Employing the results of chemical analyses available in literature sources, the authors also estimated the size of Fe, Ni and Co resources for several selected asteroids. These bodies contain higher concentrations of iron, nickel and cobalt than terrestrial deposits (those found in the earth’s crust). The total content of Fe on parent bodies of even the most deficient in metals group LL of ordinary chondrites is about twice as high as that in the earth’s crust. Cobalt occurs on parent asteroids of ordinary chondrites in concentrations 15–24 times as high as those in the earth’s crust, and the concentrations of Ni are 100–180 times as high as those in the earth’s crust. The contents of these metals on parent asteroids of ordinary chondrites are also several times as high as those in currently extracted deposits in the earth’s crust. Taking into account the mean annual terrestrial production of these metals, the authors have estimated that a parent asteroid of ordinary chondrites with the size between 433 Eros and 6 Hebe could satisfy our need for Fe, Ni and Co for the nearest several million to dozens of billion years. Considering the fact that asteroid belt contains plenty of such objects, and as many asteroids built chiefly of Fe-Ni alloy, one should regard this section of the Solar System as a practically inexhaustible source of metal raw materials. The prospect of their exploitation is probably much nearer than we can currently imagine.

The article aims to examine the peculiarities of the financial mechanism of the transboundary natural resources management, which is very diversified all over the world and comprises: trust funds, ongoing revolving funds, public-private partnerships, public funding in member countries. Promoting the transboundary cooperation of natural resources management is characterized with frequent underfunding and resolving its mechanisms is not sufficient. The lack of transboundary management funding is reflected by weak results of institutional development of the transboundary regions in their entirity. The process of funding of the transboundary natural resources management should consist of four major steps to promote the development of the transboundary institutional mechanisms: the initiation process, institutional mechanism, program realization and investments within the common management of the transboundary natural resources. The article defines the following principles of the financial mechanism for transboundary natural resources management: the principle of the annual contribution of each member country to the Euroregion budget, the polluter-pays principle, the principle of fund receiving for the provision of services. On the grounds of the analysis of foreign experiences we offer two ways of creating specific funds to support the transboundary water resources management, such as: special financing fund and basin trust fund. The effective managing of the transboundary natural resources demands the presence of the local goverment institutions which may aid the cooperation between countries and realization of the common strategy and managing policy. The proper funding of the transboundary cooperation mechanisms and transboundary institutions, which manage these resources, should be performed steadily. Especially funding the creation and maintainance of the institutional mechanisms, building a potential, developing legal frameworks, managing (including monitoring of the data exchange and evaluation), and supporting the realization of common programs of optimalization of fair use of and protection of common transboundary natural resources. All the traditional and innovative financial mechanisms should be treated as options for balanced funding of the transboundary management institutions in order to promote the common transboundary management of natural resources and support implementing the regionally coordinated policy.

Artykuł ma na celu zbadanie osobliwości mechanizmu finansowego zarządzania transgranicznymi zasobami naturalnymi, który jest bardzo zróżnicowany na całym świecie i obejmuje: fundusze powiernicze, stale odnawialne fundusze, partnerstwo publiczno-prywatne, finansowanie ze środków publicznych w państwach członkowskich. Promowanie współpracy transgranicznej w zakresie zarządzania zasobami naturalnymi charakteryzuje się częstym niedofinansowaniem i rozwiązanie jego mechanizmów nie jest wystarczające. Brak finansowania transgranicznego zarządzania odzwierciedla słabe wyniki rozwoju instytucjonalnego regionu transgranicznego w całości. Proces finansowania zarządzania transgranicznymi zasobami naturalnymi powinien składać się z czterech głównych kroków w celu promowania rozwoju transgranicznych mechanizmów instytucjonalnych: proces inicjacji, mechanizm instytucjonalny, realizacja programu i inwestycje w ramach wspólnego zarządzania transgranicznymi zasobami naturalnymi. Artykuł określa następujące zasady mechanizmu finansowego dla zarządzania transgranicznymi zasobami naturalnymi: zasada rocznego wkładu każdego państwa członkowskiego do budżetu euroregionu, zasada zanieczyszczający płaci, zasada otrzymywania funduszy za świadczenie usług. Na podstawie analizy doświadczeń zagranicznych oferujemy dwa sposoby tworzenia konkretnych funduszy na wsparcie zarządzania transgranicznymi zasobami wodnymi, takie jak: specjalny fundusz finansowania i dorzecze fundusz powierniczy. Skuteczne zarządzanie transgranicznymi zasobami naturalnymi wymaga obecności regionalnych instytucji zarządzania, które mogą sprzyjać współpracy między państwami i realizacji wspólnej strategii i wspólnej polityki zarządzania. Odpowiednie finansowanie transgranicznych mechanizmów współpracy i transgranicznych instytucji, które zarządzają tymi zasobami, powinno odbywać się w sposób zrównoważony. W szczególności finansowanie tworzenia i utrzymywania mechanizmów instytucjonalnych, budowania potencjału, rozwijania ram prawnych, zarządzania (w tym monitorowania wymiany danych i oceny), a także wspierać realizację wspólnych programów optymalizacji sprawiedliwego wykorzystania i ochrony wspólnych transgranicznych zasobów naturalnych. Wszystkie tradycyjne i innowacyjne mechanizmy finansowania powinny być traktowane jako opcje dla zrównoważonego finansowania instytucji zarządzania transgranicznego w celu promowania wspólnego zarządzania transgranicznymi zasobami naturalnymi oraz wspieranie wdrażania regionalnie skoordynowanej polityki.

This paper analyzes the economic aspects of subsidy policy in the area of small hydro power plants. It confronts the current practice with the theory and proposes an economically effective solution. It is the first of a series of contributions devoted to providing subsidies to producers of renewable energy to which, among others, belong running water, biofuels, wind and solar radiation. It is based on the results of three case studies dealing with the analysis of the economic effciency of small hydro power plants, which are solved by the "case-based reasoning" approach. The first two studies relate to the already completed and operating hydro power plants on the rivers Sázava and Litavka in the Czech Republic. Their parameters and other required data are accessible at http://www.eis.cz. The third analyzed project is in the planning stage and has not yet been implemented or subsidized. Calculations are based on budgeted data and are used for demonstration and illustration of the proposed criteria of the effective economic subsidy policy.

The aim of the article is to present the Record Sheet of Animate Natural Monuments for trees, which would standardize collecting and presenting data on tree monuments. The study uses data from the Register of Natural Monuments of the Lower Silesian Voivodeship made available by the Regional Directorate for Environmental Protection (RDOŚ) in Wrocław, as well as form the existing municipal record sheets of nature monuments and the Central Register of Forms of Nature Protection (CRFOP) facilitated by the General Directorate for Environmental Protection. Based on the qualitative assessment and the range of data contained in the RDOŚ and CRFOP registries and record sheets, an original proposal for a natural monument record sheet was elaborated for both individual trees and groups. The proposed consistent range of data on natural monuments will enable the use of collected data in statistical surveys, comparative analyses, and the research on species. In addition, the quality of data collection will contribute to a proper protection of trees and their surroundings.

Some of the practical implications of the previously identified geographic patterns linking climate rate of surface temperature with the fractal dimension of a multi-year series of runoff, are presented. The statistical data, showing a role of coefficient of kurtosis at classification of distributions of density of probability in a range of air temperatures from –5 to 27 ° С are given. It is empirically established that statistical distributions of long-term average annual runoff series for the temperature zone with prevailing high values of the fractal dimension correspond to beta-distributions of type II and when plotted on the K. Pearson diagram this type is distinguished from probability density curves in other temperature zones by kurtosis (statistically significant). It is revealed that ignoring the coefficient of kurtosis means not taking into account the climatic component of natural resources. The results of the study can be used to assess the reliability of hydraulic structures and in the field of water management.

Subject and purpose of work: The purpose of the study is to evaluate the utilisation of resources necessary for agricultural production as well as their protection in farms conducting ecological production. The deliberations undertaken in this paper focus on certified farms due to their specificity and character of their production, which is compatible with the principles of sustainable development. Materials and methods: The article uses the results of research from twenty ecological farms in the Chełm-Zamość subregion of Lublin Voivodeship. The deciding factor in selecting this region was the prominent role of agricultural production in this region when compared to the other ones in the voivodeship. Results: The research results have shown that there is a lack of correlation between actions taken by producers and caring for the natural environment. Farmers displayed little awareness with regard to the use of environmental resources and assets in agricultural production. Conclusions: Running a farm aimed at ecological production is connected with the implementation of solutions that have not found application in traditional agricultural production, with obtaining a certificate and the need for training and further study. This does not, however, translate into the introduction of pro-ecological solutions in agricultural production or the farm itself. A significant share of the investigated producers did not report the need for introducing such solutions. It indicates the need for continuous broadening of knowledge and creating ecological.

Przedmiot i cel pracy: Celem opracowania jest ocena wykorzystania zasobów niezbędnych w produkcji rolniczej i ich ochrony w gospodarstwach prowadzących produkcję ekologiczną. Rozważania podjęte w artykule koncentrują się na certyfikowanych gospodarstwach rolnych z uwagi na ich specyfikę i charakter realizowanej produkcji, która sama w sobie jest zgodna z zasadami rozwoju zrównoważonego. Materiały i metody: W artykule wykorzystano wyniki badań dwudziestu gospodarstw ekologicznych z terenu podregionu chełmsko-zamojskiego województwa lubelskiego. O wyborze podregionu zdecydowała znacząca rola produkcji rolniczej w regionie na tle pozostałych w województwie. Wyniki: Uzyskane wyniki badań wskazały na brak powiązania podejmowanych przez producentów działań z dbałością o środowisko przyrodnicze. Rolnicy charakteryzowali się niewielką świadomością dotyczącą wykorzystywania zasobów i walorów środowiskowych w produkcji rolniczej. Wnioski: Prowadzenie gospodarstwa ukierunkowanego na produkcję ekologiczną jest związane z wprowadzaniem rozwiązań nie stosowanych w tradycyjnej produkcji rolniczej, uzyskaniem certyfikatu, a także potrzebą szkolenia i dokształcanie. Nie przekłada się to jednak na wprowadzanie rozwiązań proekologicznych w produkcji rolniczej i w samym gospodarstwie domowym. Znacząca część badanych producentów nie wykazała potrzeby wprowadzania takich rozwiązań. Wskazuje to na potrzebę ciągłego poszerzania wiedzy i kreowania świadomości ekologicznej.

Plant is one of the major forms of life on earth. It can produce its own food but cannot move about. Plants have well organized structures. They are beautiful and they determine local climates and are used as live fences. They phytoremediate and cool our environment. They provide us with oxygen, medicines, fuel, timber, recreation, industrial products; preservatives, pesticides in addition to all the three necessities of life: food, clothing and shelter. They purify the air and water bodies. It is therefore impossible to talk about life without plants because of their importance to the balance of nature. However, people have altered and often degraded their environment, though it has been taking place so gradually that its effects have not been drastically felt. Despite the enormous benefits of plants to humanity, they are disappearing at alarming rates. The reasons for this loss are many and include many anthropogenic activities. It is therefore quite imperative to ensure their effective conservation. This paper summarizes available information about the direct and the indirect benefits of plants and suggests some important measures to ensure their posterity. I hope, by bringing this information together, people will appreciate our plants and be frugal in using them.

Background. The barred spiny eel, Macrognathus pancalus Hamilton 1822 (known also as the striped spiny eel) has high food- as well as ornamental value in India and its neighbouring countries. The natural resources of this species are declining due to over exploitation and habitat changes. The aim of this study was to provide necessary inputs on food habits, reproductive biology, and fishery of the species for artificial propagation programs and fisheries guidelines for conservation of its natural populations. Materials and Methods. Fish samples were collected monthly, for a period of 12 months, from an oxbow lake, situated in the Ganga River basin, India, during June 2004-May 2005. Food habits, reproductive biology, length-weight relation, fishery resource status, asymptotic length (L∞), length at maturity (Lm) and length at maximum possible yield (Lopt) for the species were studied. Results. The fish subsisted mainly on insect larvae. Fecundity range was 227 (fish: 10.7 cm and 5.03 g) to 8310 (fish: 17 cm and 30.31 g). Length at first maturity calculated through maturity curve was 10-11 cm (males) and 11-12 cm (females) in total length. The breeding period was within March-September. The regression model fitted for length and weight of the fish was Log W = 3.3224 Log L - 6.0793, R2 = 0.9094 for male; Log W = 3.3378 Log L - 6.0716, R2 = 0.9183 for female. The exponent ‘b’ for male and female varied significantly from ‘3’ indicating allometric growth pattern. The relation of fecundity with total length and weight of the fish was Log F = 2.9574 Log L - 3.2055, R2 = 0.3728 and Log F = 0.9684 Log W + 2.0934, R2 = 0.4716. Immature specimens dominated in the catch. The estimates obtained for L∞ = 18.8 cm (s.e. range 15.9-22.3 cm), Lm male = 10.8 cm (s.e. range 7.7-15.1 cm), Lm female = 12.3 cm (s.e. range 9.3-16.3 cm) and Lopt = 11.3 cm (s.e. range 9.6-13.4 cm). Biomass of the species in experimental fishing was high during October-January, which was also the period when immature specimens were lowest. Conclusion. Closed or less intense fishing for the species during March-September and capture of only specimens above 14 cm length would help conservation of the natural stock of the fish in the wetland.
