“…These combined factors are particularly widespread at the urban-rural fringe, where both intensive commercial operations and hobby farms exist on a small land base, and sewage services are limited. This mix of land uses often results in diffuse and widespread nonpoint sources of pollution, making it difficult to protect the quality of both stream and ground water resources (Meybeck and Helmer, 1992;Harper et al, 1992).…”

: Agricultural and residential activities are key non‐point sources of nitrogen pollution in urban‐rural fringe areas. A GIS‐based watershed approach was used to compare land use indicators (septic system and animal unit densities), to streamwater nitrate‐N in the Salmon River near Vancouver, B.C., Canada. The density of septic systems was used as an indicator of residential development while animal unit density was used as an indicator of the intensity of agricultural activity. Nitrate‐nitrogen (nitrate‐N) concentrations as high as 7.1 mg·L−1 were found in the mid‐portion of the watershed during the summer months, when streamflow is low and groundwater comprises a large proportion of water in the stream. The major aquifer supplying water to the midsection of the watershed is contaminated with nitrate‐N. A comparison of the relationships between septic system and animal unit density and nitrate‐N in the upstream to downstream direction provided evidence that both residential and agricultural activities contribute to elevated nitrate‐N in the Salmon River mainstem. In contrast, only septic system density corresponded to the pattern of streamwater nitrate‐N in Coghlan Creek, the main tributary to the Salmon River.

“…Nitrate contamination would rise rather than fall, because the nitrate loading coefficient for this land use is larger (roughly double) than that of agriculture. This much was shown by Harper, Goetz and Willis [1992].…”

Geographic Information Systems (GIS) are becoming increasingly important to virtually all of the natural and social sciences. Applied economists will find that GIS can make valuable contributions to many of the problems with which they are concerned. Moreover, a great deal of the science behind GIS technology would benefit from the contributions of applied economists. This paper presents some initial suggestions for the ways in which GIS may be important to economics and the GIS related issues concerning which applied economists could provide useful insights.

“…Zoning plans, sewer extensions, and road construction, in combination with population projections, can suggest a great deal about the potential effects of population growth on wetland services and values. Intensive agriculture or feedlot operations and unsewered medium-and lowdensity residential land use have also been shown to be strong predictors of pollutants in groundwater and surface water (Harper, Goetz, and Willis 1992;Hall et al 1994). Plans for these types of land uses adjacent to or upstream of a wetland suggest increased risk.…”
