“…Various authors are of the view that permanent and seasonal changes within wetlands occur in response to a range of external factors, such as the changes in the land systems at the catchment scale [28][29][30], fluctuations in water table [31], climate change [32], besides other human activities [33]. Generally, wetlands are known to function as biofilters in hydrologic systems [34], besides retaining and transferring nutrients (N and P) from aquatic ecosystems [35].…”

Hokersar wetland suffers highly due by nutrient inputs from the catchment area, internal wetland processes and various types of anthropogenic pressures around. To characterize nutrient dynamics of the wetland, nitrogen (N) and phosphorus (P) samples were collected from six study sites in the Queen wetland of Kashmir Himalaya for a period of one year from Sep. 2012 to Aug. 2013. Clear spatial and temporal variations were observed among the recorded parameters (ammonical nitrogen, nitrate nitrogen, total orthophosphate phosphorus and total phosphorus) throughout the year. Ammonical nitrogen concentration was found to be maximum in winter (242.3±10.1 µg/L). Lower nitrate nitrogen was observed in summer, recording 259.6±35.3 µg/L. Both the forms of phosphorus registered higher values in summer and lower values in winter. Scatter plot showed highly significant values among all the parameters (R²=0.748 and 0.719). Principal component analysis showed highest principle component vector displacement among the sites IV and VI reflecting polluted nature of the sites. Further, higher Eigen-vector displacement values were due to ammonical nitrogen and nitrate nitrogen, registering values 3.36724 and 0.542639 respectively. Similarity matrix was highest between total phosphorus and ammonical nitrogen (92.9666%), followed by ammonical nitrogen and nitrate nitrogen making 58.5729%.

“…Our objectives are: (1) to explain that water quality is an integrated result of positive and negative influences of land uses, (2) to quantify how much the influence of spatial pattern of land use on the surface water quality (Gillies et al 2003), and (3) to test the dynamic complex hypothesis. We used buffer analysis and pattern analysis techniques to investigate the correlation of land uses with water quality in watershed varied with buffer distance along lakeshores by a stepwise regression model.…”

In this study, we proposed a dynamic complex hypothesis that the impact of land use on water quality could vary along the expansion of the buffer size, and there should be an effective buffer zone where the strongest linkage occurs between land use and water quality. The hypothesis was tested and supported by a case study carried out in four watersheds in Hanyang District, China. More specific, buffer analysis and regression model were applied for studying the impacts of land use type, area proportion of land use type, and spatial pattern of land use on water quality. We conclude that not only the proportion of land use but also the spatial pattern moderates the impact of land use on water quality. Our study indicates that the identification of the effective buffer zones can provide new information and ideas for planning and management. Moreover, this study could also partially help to explain the conflicting results on the impact of land use on water quality in buffer versus in catchments in the literatures.

“…Measuring surface sealing is an important issue when studying flood control and urban hydrology (Jennings and Jarnagin, 2002;Jennings et al, 2004). It is no surprise that the evolution of sprawl and semi-urban areas is narrowly followed by hydrologists (Gillies et al, 2003;Hall, 1989;Hoggan, 1989;Pauleit et al, 2005;Shaw, 1988;Zheng and Baetz, 1999).…”

Urbanization is a well-known topic in sustainable development debates as it is known to have great impacts on landscape and environment. Low density, apparently random, scattered or fragmented and leap frogging forms of urban land use, not classified as core urban fabric (town, city, . . . ) nor classified as real 'countryside' are studied in this paper. With a thorough literature study of more than 200 publications, a number of interesting conclusions about this important environmental and socio-economical phenomenon can be made. At first, it is generally described as either a type of land use or land use dynamic functioning as 'divide' between city and countryside (the urban fringe theory), or it is very often described as the dynamic and fast transformation of rural land into urban land (the sprawl approach). In some cases it forms its own 'landscape' and it is called the peri-urban or more correctly semi-urban area. Generally, there seems to be a lack of good definitions and frameworks, although it is studied often and in various scientific disciplines. Prominently, there is an always present dichotomy between rural and urban in all concepts, theories and definitions proposed.
