The contribution of scenic views of,and proximity to,lakes and reservoirs to property values

Water is arguably the world's most critical resource, although its aesthetic and recreational functions typically receive less attention than its consumptive uses. Views of, and access to, attractive water resources are capitalized into property prices in the form of sales price and rental premiums, measured since the 1970s with the hedonic pricing technique. This study synthesizes the evidence to date with respect to the value of lakes and reservoirs as aesthetic and recreational resources to nearby residents. Findings are reported relating to the effects of scenic views of, and proximity, to reservoirs and large artificial lakes, the North American Great Lakes, and other smaller inland lakes. Of the 44 distinct reviewed studies that included tests of statistical significance, only two failed to produce any significant findings in the directions anticipated (i.e., a positive impact of water frontage or view and/or negative impact of increasing distance). Improvements in methodological approaches—from early studies employing anecdotal observation and visual comparison to more recent investigations employing advanced geographical information systems and rigorous spatially explicit regression techniques—are traced. The potential implications of climate variability and changes for property values are addressed, as is the growing movement towards the adoption of green infrastructure. The need to consider changes to aesthetic and recreational values, in addition to outcomes for more traditional consumptive uses during cost–benefit analyses associated with proposed (re)developments, is emphasized.     

公路建设产生弃土、弃石、弃渣量的预测

拟建公路所经过的地形地貌不同,建设过程中将产生的弃土、弃石、弃渣量差别较大.公路工程在建设过程中产生的弃土、弃石、弃渣量的多少,直接关系到工程造成新增水土流失量的预测和弃渣场的水土保持防治措施的布置.弃渣场的防护是水土保持方案的重要内容之一,若工程建设过程中产生的弃土、弃石、弃渣量的预测不准,将导致水土保持方案新增投资不足,从而影响后续工作的开展.对预测方法作了系统介绍.

Alewife Mortality,Condition, and Immune Response to Prolonged Cold Temperatures

Alewife, Alosa pseudoharengus, have been recognized for several decades as one of the most important forage fish in the Laurentian Great Lakes. Although massive alewife die-offs have regularly been observed throughout the Great Lakes and other inland lakes, little substantive information is available regarding physiological mechanisms associated with adult alewife mortality. Long-term field surveys have shown a correlation between cold winter temperatures, poor condition and adult alewife mortality. In this study, adult alewife were raised in replicate pond systems and subjected to contrasting cold temperatures (4 and < 2°C) representing mild and severe winter conditions. We evaluated alewife mortality, condition and immune response to these temperatures. In contrast to our expectations, alewife exposed to mild and severe winter temperatures showed no difference in mortality or condition (measured as the ratio of dry to wet weight). Survival of alewife held in ponds with mild winter conditions (∼ 4°C) was similar to that of alewife exposed to prolonged periods (more than six weeks) of temperatures < 2°C. This result contrasts with previous observations indicating that alewife cannot tolerate temperatures < 3°C. Circulating lymphocytes from alewife exposed to severe winter temperatures were significantly lower in number (∼40%) compared to fish experiencing milder° winter conditions, suggesting sub-lethal immunosuppression in response to the colder winter temperatures. Although colder winter temperatures did not directly induce alewife mortality, these results suggest that winter conditions that result in colder water temperatures can produce immunosuppression, thereby increasing alewife susceptibility to disease and mortality.

Guyana, “Land of Waters,” Moves to Harness Hydro Potential

ABSTRACT

Heavy metal concentrations (cadmium, chromium, lead, zinc) in 46 cistern water supply systems from single-family dwellings on St. Maarten, Netherlands Antilles were considerably below US drinking water limits in most cases. Release of zinc, lead, and cadmium in the distribution system, which is not related to the corrosiveness of the cistern water, caused lead and cadmium to exceed the US Public Health Service standard for 3 (6.5%) and 1 (2.2%) of the cisterns, respectively.

The following recommendations are suggested for protecting the roof catchment drinking water supply against heavy metal contamination:

? engineer the withdrawal of cistern water to exclude the metal-laden sediment

? identify appropriate paints to be used for cistern collection systems

? install substituted materials, protective coatings, and replacement of corroded metal parts in the distribution system

? discourage the usage of metal containers (e.g., oil) for prolonged water storage

? expand cistern water quality analyses to include lead

? exercise plumbosolvency control by treating the cistern water before distribution.

These recommendations, based on the case study, also apply to other areas of the world where cisterns of similar construction are used or are being planned.
