“…The negative influence of the catchment area mainly consists in supplying excessive loads of nutrients to waterbodies, which accelerate their eutrophication 15 , 29 . Every year the amount of pollution from the catchment area increases, mainly due to the intensification of agricultural production 30 , 31 . These pollutants include both mineral fertilisers and sewage of animal origin, including slurry from smaller farms and liquid manure from large livestock farms.…”

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.

“…1). Together with researchers and students from the University of Zambia, landowners and administrators, we purposively selected appropriate sites so as to highlight contrasting agricultural and natural landscape features of importance for the water, energy, food, ecosystem nexus in Zambia (Winton et al, 2021), including forests, rivers, wetlands, small-, and large-scale cropping systems. All flights were carried out by a licensed drone pilot with permission from the Zambian Civil Aviation Authority and supervised by a member of the Zambian Air Force.…”

Anthropogenic influences on Zambian water quality: hydropower and land-use change

Abstract: Hydropower dams along with urban and agricultural land-use changes are altering surface water quality in the Zambezi River Basin, Zambia. Field data reveal local impacts and point to monitoring needs for safeguarding water resources under pressure.
