The paper deals with modern geosystem problems and suggests ways of solving them. The main aim of the study is to develop new methods of geosystem preservation on the base of geoecochemistry through geoecochemical reactions. Both theoretical, namely thermodynamic, method and experimental one are used in the research. Three new geoecochemical techniques such as energy economy, soil restoration and alternative technologies are introduced for natural resource preservation. Every technique is estimated with relation to negative changes of Gibb’s free energy. These changes take place as a result of geoecochemical reactions and determine a level of geosystem preservation. Using the first technique it is possible to save energy, a few hundreds of kilojoules per mol, due to formation silicates, phosphates, etc. Other techniques of geosystem restoration are heavy metal ion detoxication and alternative technologies, e.g. lithosynthesis, for natural resource preservation. Geoecochemical techniques of lithosphere preservation can be useful for any geoconstruction technology like soil strengthening, highway and railway construction and other earthwork operations.

Sub-Saharan Africa (SSA)’s natural resource base constitutes the sub-continent’s greatest asset. These Natural Resources (NRs), both renewable and non-renewable, are the backbone of the continent as they play very critical functions in the livelihood strategies of the people. There are a wide range of questions and issues concerning the proper management of these NRs. One of the issues relates to the economics of resource preservation, which includes questions associated with the quantifiable benefits of resource preservation, the environmental costs and benefits of Soil and Water Conservation (SWC) strategies, the economic impact of land use changes, and valuation of ecosystem goods and services. The other issue concerns the ecosystem and economic system interaction. Particular themes of interest are the co-management of natural resources, trans-boundary natural resource management, and the management of resources to reconcile revenue generation, social development, and environmental services of natural resources. This chapter reviews the literature on quantitative approaches that have been undertaken to enhance the understanding of selected Natural Resource Management (NRM) problems on the continent. The review suggests that a wide range of quantitative approaches have been applied in the context of the African resource economics literature, but this review also identifies some specific areas that have received little attention.

Aims/Objectives: An agricultural tropical soil treated and untreated with swine manure was evaluated to Pb2+, Cu2+, Zn2+, and Ni2+ competitive sorption dynamics.Study Design: Metal ion mobility patterns were evaluated by sorption-desorption reactions with the mineral and organic matter soil phases. Place and Duration of Study: Agronomic Institute of Parana (IAPAR) at Londrina city, Parana State, Southern Brazil, in an experiment conducted since June 2008.Methodology: Soybean and corn were growing up in the experimental area in summer and winter, respectively. Swine manure (SM) was applied twice a year, and the amount was calculated according each crop necessity. Experiments were in batch, varying the metal ion concentrationfrom 1.0 to 10 meq L−1. After equilibrium, the solid phase was analyzed by EDXRF and liquid phase by ICP-OES. Metal ion mobility was evaluated by applying the dual-mode Langmuir- Freundlich mathematical model, in addition to rate removal and Gibb’s free energy determination.Results: Sorption capacity increased after the SM amendment, and the retention sequence Pb2+>Cu2+>Zn2+>Ni2+ was observed. The sorption capacity increased in 30%, 45%, 176%, and 231% for Pb2+, Cu2+, Zn2+, and Ni2+, respectively. The relative intensity of the fluorescence emission lines showed metal ion sorption increased after the amendment, keeping the same sequence observed for the adjustable parameters from the fitting by dual-mode Langmuir- Freundlich model. Conclusion: The possibility of a controlled release of micronutrients, considering low-affinity sorption sites, brings an excellent look to the swine manure amendment.

In the current scenario street lights are turned as an imperative ingredient. As we know plenty of electricity is squandered by street lights. So there is a necessity to rescue power as much as possible. As there exists decay in energy which is proportional to escalate the price of electricity. It is the necessity to save energy, street light monitoring system is fully automated to ameliorate the effectiveness of switching operations of street light monitoring. The Street Light Monitoring System focus is to model an astute advancement in technology by utilizing wireless technology (GSM). Each and every street light is supervised by the server based operated system which sends a information using wireless network (GSM Module) which incorporates client server solicitation which leads for effective supervision and energy economy dominance of street light monitoring system is very crucial.

The Society of Wilderness (SOW) is a non-governmental organization in Taiwan that relies on volunteers to protect nature through environmental education. Since volunteers play such an important role in natural resource preservation, more information is needed to understand their participation in SOW. The purpose of this study was to develop an interpretation specialization continuum of environmental volunteerism in Taiwan. A mail-back survey was administered to interpreters volunteering at Er-ge Mountain during the winter of 2005. Forty-five of 48 questionnaires were returned, yielding a 93.8% response rate. The resource knowledge and place attachment scores of volunteer interpreters were combined into a 2 x 2 matrix, thus providing one explanation for their level of activity involvement in SOW. Although volunteer interpreters were distributed throughout the continuum, results showed that highly specialized interpreters had greater activity involvement scores than those who were less specialized. Length of membership in SOW had no effect on their activity involvement scores. This specialization continuum addressed key managerial issues, such as recruitment and retention of volunteer interpreters.

Charismatic fauna can play a critical role in how we navigate the challenges of natural resource preservation and conservation. Their highly relatable appeal makes them ideal candidates for conservation campaigns, branding, and marketing, while their easy identification is valuable for ecotourist experiences. The revenue generated from both ecotourism and conservation campaigns (donations indicate a willingness to pay) can help assign a recognized value to our natural world and all its natural capital, making conservation rather than development our economic choice. For many people, the plight of highly recognizable charismatic species embodies the biodiversity crisis, as relying on their appealing faces as proxies for habitat protection makes sense. Their presence has the potential to generate ecotourist dollars that can be used to preserve and protect ecosystems and habitats beyond their own terrains, creating an umbrella effect. The benefit of utilizing charismatic fauna as surrogates for larger ecological issues is how effectively these animals can be used to protect the landscapes and biodiversity of entire ecosystems.

AbstractPollution from fossil fuel use is a global problem. Studies have shown that a worsening of environmental quality has adverse effects on worker productivity and health. In this study, there is an inexhaustible natural resource that deteriorates environmental quality and affects productivity. There also exists a perfect substitute clean backstop, which is initially too costly to operate and whose costs can be reduced through investments in knowledge. Depending on the endowment of environmental quality, the optimal solution shows that the planner should only use the resource or only the backstop until a constant steady state is reached in which the polluting resource and backstop are used in fixed proportions. We show that investments in alternative technologies from the very beginning can help an economy make the eventual switch to clean energy sources, thereby attaining better environmental quality.

We are approaching the invasiveness of cancer cells from the studies of their wet surface morphology which should distinguish them from their normal counterparts. In this report attempts have been made to provide physical basis and background work to a wet replication method with a differentially pumped hydration chamber (Fig. 1) (1,2), to apply this knowledge for obtaining replica of some specimens of known features (e.g. polystyrene latex) and finally to realize more specific problems and to improvize new methods and instrumentation for their rectification. In principle, the evaporant molecules penetrate through a pair of apertures (250, 350μ), through water vapors and is, then, deposited on the specimen. An intermediate chamber between the apertures is pumped independently of the high vacuum system. The size of the apertures is sufficiently small so that full saturated water vapor pressure is maintained near the specimen.
