The influence of land use in the catchment area of small waterbodies on the quality of water and plant species composition

Abstract

Land use significantly affects the function of waterbodies in landscape. Although there have been numerous studies on the influence of the catchment area on the trophic and ecological status of waterbodies, still is not reached an agreement on the width of the buffer zone that is necessary for effective protection of waterbodies. The aim of the study was to show whether small waterbodies are predominantly influenced by land use in the entire catchment area or only in the zone extending 100 or 200 m away from the shoreline. For two years the waters in six small waterbodies located in the Wielkopolska region (Poland) were analysed. The canonical correspondence analysis (CCA) showed that the influence of land use, especially agricultural land, was much greater within the zone extending 100 m from the shore line of the waterbodies than in the total catchment area. Therefore, it would be advisable to move the border of intensive farming areas beyond the entire 100-m-wide buffer zone, or at least to reduce the intensity of agriculture and to introduce diversified and perennial vegetation creating effective biogeochemical barriers.

The relationship between water quality and riparian zone land-use variables and macrophyte removal permits issued in between 2013-2020 in the Rideau Canal Waterway

“…These findings are also consistent with those of Szpakowska et al (2022), where a canonical correspondence analysis showed that farming, had the greatest influence on water quality and vegetation in small waterbodies. The analysis specifically showed that arable land located in the buffer zone, extending to 100m form the shoreline had the greatest influence.…”

“…It was also determined that catchment area is a good predictor of both permits and permits per kilometre shoreline. In a study by Szpakowska et al (2022), the authors concluded that the catchment areas of waterbodies significantly affect small aquatic ecosystems.…”

“…Specifically, as the distance from the shoreline increases, the influence of the catchment area decreases (Szpakowska et al, 2022). This offers an opportunity for future research to examine the relationship between catchment area size in relation to the number of permits being distributed on lakes within a canal system and the potential implications on aquatic ecosystems and macrophyte communities.…”

Assessing the relationship between river water pollution and the LULC composition of a basin in the Isthmus of Tehuantepec in Oaxaca, Mexico

“…Since the 1970s, remote sensing, GIS, and statistical techniques have been used to assess the interactions between terrestrial and aquatic systems (Xu et al, 2001). Numerous studies have investigated the relationship between landscape composition and surface water quality ( (Wang et al, 2023), cellular automata-Markov models (Yao et al, 2023), arti cial neural networks (Wang & Zhang, 2018;Zhou et al, 2016), redundancy analysis (Zhao et al, 2015), canonical correspondence analysis (CCA) and canonical regression analysis (Szpakowska et al, 2022;Luo et al, 2020;Luo et al, 2018).…”

Revealing the Land Use Volatility Process in Northern Southeast Asia

“…About three-quarters of the Earth's land surface have been altered within the last millennium as a result of human activities and natural processes [1][2][3], which also brings a variety of ecological and environmental problems [4][5][6]. Changes in land use and land cover affect directly the Earth's energy balance and the biogeochemical cycle, and also have an impact on hydrological processes and water cycles [7], climate change (precipitation and temperature) [8], carbon cycles [9], biodiversity [10], and forest degradation [11]. For example, at the expense of ecological functions, large expanses of lowland tropical rainforest have been converted to large-scale commercial plantations or small-scale mosaic agricultural landscapes in Indonesia [12].…”
