A recreation impact monitoring system was developed and applied in 1984–1986 and in 1991 to all backcountry river-accessed campsites within Delaware Water Gap National Recreation Area, Pennsylvania and New Jersey. Results suggest that actions implemented by park managers in response to problems identified by the initial survey were highly effective in reducing resource degradation caused by camping. In particular, the elimination of some designated campsites and installation of anchored firegrates reduced the total area of disturbance by 50%. Firegrate installation provided a focal point that increased the concentration of camping activities, allowing peripheral areas to recover. As suggested by predictive models, additional resource degradation caused by increased camping intensities is more than offset by improvements in the condition of areas where use is eliminated. The capabilities and management utility of recreation impact monitoring programs, illustrated by the Delaware Water Gap monitoring program, are also presented and discussed.  相似文献

In work, we compared two models for dealing with urban solid waste in Brazil, namely, management by contract and management by public–private partnership. Management by contract, which is widely used by the public sector (municipalities) for urban solid waste collection and disposal and for acquiring goods and services for periods not greater than 60 months, is governed by Federal Law 8.666/93. Management by public–private partnership is governed by Federal Law 11.079/04 for contracts worth more than US$11,000,000 and involves costs for the private partner and public partner. The financial return for the private partner must be clearly delineated and the contract should last from 5 to 35 years. Management by public–private partnership that involves the management of municipal solid waste is very recent in Brazil. For this reason, the comparison between the two forms of management of municipal solid waste (management by contract and management by public–private partnership) described in this work is unprecedented in this country. Both of these models are used in the municipality of São Bernardo do Campo in the State of São Paulo, Brazil. For this study, information was gathered through semi-structured interviews with public works managers in São Bernardo do Campo, with members of an Association of Recyclable Material Collectors and with managers of a company contracted by the São Bernardo do Campo city hall, and also by researching public documents provided by the city hall. The interviews with the managers of the municipality of São Bernardo do Campo, the Association and the company were held in the headquarters of each institution. The documents analyzed, such as the plan for dealing with municipal solid waste, contracts and bids were made available electronically. Analysis of the results indicated that management by a public–private partnership was more advantageous for dealing with urban solid waste than management by contract since the former provided a strong selective collection program, reduced the amount of solid waste sent to sanitary embankments, led to the recovery an area of land previously degraded by the incorrect disposal of urban solid waste and stimulated the installation of an energy recovery unit.  相似文献

Both the bioavailability of a trace metal (TM) in a soil and the risk of leaching to the ground water are linked to the metals concentration in the soil solution. Sampling soil solution by tension lysimetry with suction cups is a simple and established technique that is increasingly used for monitoring dissolved TM in soils. Of major concern, however, is the sorption of TM by the walls of the samplers. Metal sorption by different materials used in suction cups can vary widely, depending also on the chemistry of the soil solution. We compared the sorption of Cu, Zn, Cd, and Pb by different standard-size and micro suction cups in the laboratory at two pH values (4.5 and 7.5 or 8.0) in absence and presence of dissolved organic carbon (DOC). In addition, we investigated the sorption of DOC from different origins by the cup materials. At both pH values, the weakest sorption of all four TMs was exhibited by standard-size suction cups based on nylon membranes and by hollow fibers made from polyvinyl alcohol (PVA). At alkaline pH, borosilicate glass, ceramic materials, and polytetrafluorethylene (PTFE) mixed with silicate were characterized by generally strong sorption of all investigated TMs. In addition, Cu and Pb were strongly sorbed at low pH by PTFE-silicate and a ceramic material used for the construction of standard-size suction cups. On the other hand, sorption of Cu, Zn, and Cd by ceramic capillaries produced from pure aluminum oxide was negligible at low pH. Micro suction cups made of an unknown polymerous tube sorbed Cu strongly, but were well suited to monitor Zn, Cd, and Pb at low pH, and, in the presence of DOC, also at high pH. Major cations (Na+, Mg2+, K+, Ca2+) and anions (Cl-, NO3-, SO4(2-)) were not or very weakly sorbed by all cup materials, except for Mg2+, K+, and Ca2+ by borosilicate glass at pH 7.5. Trace metal sorption by suction cups was generally greatly reduced in the presence of DOC, especially at alkaline pH. The sorption of DOC itself depended on its source. Dissolved organic carbon from leaf litter extracts with a probably large hydrophobic fraction was sorbed more strongly than mainly hydrophilic DOC from a mineral soil solution.  相似文献
