The main target of this paper is to develop the hypothesis that water intake fees can be an efficient tool for the management of water consumption in Poland. The sample used in the research consists of 600 municipal water operators with a market share over 80% in the municipal sector. The analysis comprises several tasks: firstly – the investigation of the relation between water intake fees and the structure of the costs of water provision; secondly – the investigation of the influence of fees on unit prices and a review of their changes over the last decade; and, thirdly – the analysis of demand elasticity in order to estimate demand reaction. The results obtained give an estimation of possible savings in water usage in Poland that would result from changes in the system of water intake. The analysis includes all the mechanisms of fee reductions, or exemptions for certain purposes, of existing water intake in Poland. This analysis compiles, compares and processes incremental results from several pieces of research led by the author over the last 10 years for the Ministry of the Environment the National and Regional Water Boards and also for the Institute for Meteorology and Water Management. Research was focused on the economic analysis of water usage from a more general view, however, water intake fees are taken into account in these papers, although not as separate targets for investigations.
The paper describes the current conditions, process, and consequences of the land reform in Ukraine, and goes on to determine their impact on the support for sustainable land management. The research reveals the importance of land development as the main instrument for sustainable land management in Ukraine, which should involve implementation of land policy, organization of rational use and protection of land, land improvement, crop-engineering, and anti-erosion measures. In the present paper, we argue for the measures of sustainable management, which are secured by the development of the programs of land organization, and we present technical and economic reasoning for the use and protection of land in administrative-territorial units, land development projects, as well as environmental and economic arguments for crop rotation and land management, implemented within work projects of land organization at regional, provincial and local levels. Structural instability of the establishment of agrarian formations of a new type, which are basically grounded in the fundamentals of land lease, is caused by a permanent delay on the moratorium for the sale of land parcels by the owners of land shares. It forces most of those owners to engage in economic activity without any pre-existing projects of land organization, which would provide ecologically safe organization of the leased land exploitation. Nowadays, the use of the leased land parcels, and growing of agricultural crops on those parcels, is performed mainly according to the market conjuncture and without any management methods, which would be necessary for securing land protection and maintaining soil fertility.
Recently lack of sustainable management for the reservoir watershed becomes a predicament for the water issues in Taiwan. The study tried to recognize the framework of the sustainable management of the Taiwan reservoir watershed and its key factors by using the analytic hierarchy process and the Delphi method. Through the identification questionnaires and the CVM (contingent valuation method), it also discussed the gap of expert and public for the identification of satisfaction, environmental protection and the potential value for the recent reservoir watershed. However, the results showed that the “natural stability” is the significant factor in the first level and the “Nature resources conservation” and “Water storage amount” are the most important factors for the detailed level. In addition, the expert opinions were not proved by public identification, and the present governance budgets are too low to respond to the potential values of public expectancy.
Current and future climate conditions and their impact on water balance, ecosystems, air quality and bioand agro-climatology were investigated in the region of the Lusatian Neisse within the two EU -projects – NEYMO and KLAPS. This work focuses on the climate analysis of the region at the German-Polish border as a preliminary step for a hydrological analysis of current and future conditions. Observed climatological data were processed and analysed using the indicators air temperature, precipitation, sunshine duration, potential evapotranspiration and the climatic water balance (CWB). The latter defines the difference between precipitation and potential evapotranspiration and is a measure for the climatological water availability in the region. Observations were used to statistically downscale data from Global Circulation Models under various scenarios regarding greenhouse gas emissions (A1B, RCP 2.6, RCP 8.5) and applying the WETTREG-method for regionalization. In total, 50 climate projections for periods up until the end of the 21st century were analysed, with the application of the mentioned indicators. For the period 1971-2010, increasing trends of temperature, precipitation, sunshine duration and potential evapotranspiration were found. This leads to a reduced CWB in the summer half-year (SHY), which could be partly compensated by an increase in the winter half-year (WHY). Trends of temperature, sunshine duration and potential evapotranspiration remain positive for the far future (2071-2100), but precipitation decreases. These climatic conditions aggravate water availability, especially in the SHY. Impacts on water management are very probable and were therefore further investigated in the NEY MO project that applied hydrological models.
Water harvesting systems are traditional technologies that have met the needs of local populations for many centuries indicating the systems are clearly sustainable. It is simply defined as a method for inducing, collecting, storing and conserving local surface run-off for future productive use. It is one of the oldest and most commonly used sustainable water management systems in India. There are various types of systems to harvest rainwater in India ranging from very simple to the complex industrial systems. Examples of traditional rainwater systems in India include bamboo pipes and Apatani systems of eastern Himalayas, Ghul of western Himalayas, Zabo and Cheo-ozihi of north eastern India, Dongs, Garh and Dara of Brahmaputra valley, Kund, Khadin, Talabs, Beri, Johad, Baoli etc. of Thar desert and Gujrat, the Havelis of Jabalpur, bandh and bandhulia of Satna, virda of Gujarat, ahar-pynes of Bihar, Eri and Kulam of eastern coastal plains, Jackwells of islands, most of which showed immense structural simplicity and high efficiency. Almost all forts in India, built in different terrains and climatic conditions, had elaborate arrangements for drinking water. Most of the old temples in south India built centuries ago have large tanks in their premises. These tanks are either fed by harvested rain water or by tapping underground springs. The traditional water-wisdom at all levels of the society ensured adequate availability of water for all, which in turn, formed the basis for all round development and prosperity. We should again learn and comprehend the ancient knowledge and apply it in our modern society to get rid of the present water stressed condition.
Development culture, based on the dominance of man over nature and the built over the natural, continues to predominate. To take one example, the demands of an ever-increasing number of amateur fishermen are satisfied by financing the continuous re-stocking of rivers with juvenile or small-size fish while ignoring the extinction of native species, and the damage caused by the introduction of non-native species. This method of management, and the slow acceptance of the concept of environmentally sustainable planning, is partly due to the slow translation of the results of biological and ecological research into the standardised and integrated parameters of environmental analysis necessary for planning. The new Indices for assessing river-bank quality (developed for the River Adige but tested on ther rivers) may well provide a useful step forward. These Indices, combined with others already in use or under development, may help to define a system of areas of differential tutelage along the course of a river and in the surrounding territory in which human activities and development will be compatible with conservation and rehabilitation of the river's self-purifying capacity, while at the same time allowing for effective flood defence and the reproduction of native fish species.

In this paper the authors describe the steps of building of a new automated complex land evaluation system based on the D-e-Meter land quality index. Complex evaluation means an organic systematization of ecological and economical factors. Necessary of development of a new land evaluation system based on the undeveloped land market in Hungary, which causes difference between the level of actual land price and economic value of agricultural land. The land evaluation has - among others - an important task: that is to convey the value towards the land market actors, which can be the starting point in negotiation about market price and in decision-making about the land use. The estimated land value indicates the total values of land estates on the basis of their rent-production ability. These values can differ from land-estate prices formed on land market, nevertheless they are decidedly adequate to replace the Hungarian current land evaluation system, so called Gold- -crown System and to solve whole series of objectives connected with land evaluation. The new land evaluation system is useful for estimating the realistic land value, but also helps to manage the land use on sustainable way.
The applicability of Mean Individual Biomass (MIB) of Carabidae as an indicator of succession stage was tested on 35 forest stands in western Poland. The differences in MIB values as well as similarity indices (Jaccard index, Wainstein index) were calculated between two inventories at the study sites separated by a time span of 13 years. The hypotheses were set that (1) MIB values increase with time on the study areas and (2) the differences in MIB values are negatively correlated with the corresponding similarity indices. The results show an increase in numbers of species and individuals of big sized carabids in the total samples. MIB values increase at the vast majority (85.7%) of the individual study sites between the two inventories. The increase in MIB shows a significant negative correlation with both similarity indices. The correlation is more pronounced when using the Wainstein index. The results verify the applicability of MIB of Carabidae as an indicator of stage of succession. Based on the results we suggest MIB as a useful tool in forest research and forest management.
Proper multidimensional management of perch, common and one of the most abundant species in European freshwaters, is a challenge both from ecological and commercial perspective. However, all activity relating to the management of the perch must be based on good genetic knowledge in order to ensure a purity of species and further conservation of biodiversity. Therefore, in the present study, the mtDNA cytb and D–loop restriction analysis was applied in order to estimate genetic diversity within and among three perch (Perca fluviatilis L.) populations in reservoirs of Central Poland: Sulejów, Próba and Jeziorsko. Two out of nine, and two out of eight restriction enzymes were polymorphic for cytb and D–loop, respectively. Five different haplotypes were detected with the simultaneous occurrence of haplotype 1 in all three populations. Nucleotide diversity values within investigated populations were low (0.003 to 0.02). No significant differentiation (P = 0.248) among populations representing two different catchments of Pilica and Vistula rivers, was observed. The lack of genetic differentiation of perch populations is the first important element for the development of a strategy to regulate the perch in Polish river systems, with simultaneous reduction of fish in eutrophic reservoirs and increase in amount of perch, in sites favorable for fishing and aquaculture.
Buxa Tiger Reserve (BTR) is located in Alipurduar Sub Division of West Bengal, India. It comprises of the entire forest area of the erstwhile Buxa Forest Division (Created in 1877 – 78) and some territory of the erstwhile neighboring Cooch Behar Forest Division. The Reserve lies between Latitudes 23o30′ N to 23o50′ N and Longitudes 89o25′ E to 89o55′ E. The total area of the reserve is 760.87 km2 of which 385.02 km2 has been constituted as the Buxa Sanctuary and National Park (Core zone of the BTR) and the balance 375.85 km2 areas is treated as a buffer zone. It has 37 forest villages and 4 fixed demand holdings, 46 revenue villages and 34 tea gardens in and around it. The survey work was done in May, 2015 by visiting a forest edge village, 28 Mile, in Buxa Tiger Reserve and the primary data were gathered through field survey and direct contact with common people and authorized centres of the region. Surveys on the demography, agriculture, livestock management, water management, education, culture, health, waste management, disaster management, transport, biodiversity, joint forest management activities, Non-timber forest product usage and human animal conflict were done in this area. In every phase of the survey work, photographic documentation was done. In spite of being positioned in a diverse and sensitive ecological zone, the village is not adequately managed. There is an urgent need for implementing sustainable management systems in the areas for the betterment of the socio-environmental structures. Some of the possible management strategies have been suggested for maintaining the social, environmental, economic and ecological balance of the region.
