Freshwater biodiversity on farmland
Freshwater resources are of vital importance in sustaining human populations and activities. The biodiversity of freshwater systems in agricultural land can be negatively affected by agricultural activities. The impact of land use and agricultural activities on biodiversity at two scales was investigated. Firstly, how the amount of different land-use types surrounding streams and rivers at the entire catchment scale can affect the quality of freshwaters, as measured by macroinvertebrate indices. Secondly the study looked at how adjacent land use and management affected the water quality and biological communities of agricultural ditches, often the first concentration points of water running off from agricultural land. We have demonstrated that targeting management, such as increasing woodland close to river banks and managing hedges next to ditches, could have beneficial effects on the water quality and biodiversity of freshwater on agricultural land.
