      description => protected'The Zambezi River Basin in Southern Africa is undergoing rapid development a
         nd population growth. Agricultural intensification, urbanization and future 
         development of hydropower dams will likely lead to a degradation of surface 
         water quality, but there have been few formal assessments of where, how and 
         why these changes impact specific water quality parameters based on <em>in s
         itu</em> data spanning a large region. We sampled a large suite of biogeoche
         mical water quality parameters at 14 locations in four field campaigns in ce
         ntral and southern Zambia in 2018 and 2019 to characterize seasonal changes 
         in water quality in response to large hydropower dams and human landscape tr
         ansformations. We find that the major rivers (Zambezi and Kafue) are very cl
         ean with extremely low concentrations of solutes, but suffer from thermal ch
         anges, hypoxia and loss of suspended sediment below dams. Smaller tributarie
         s with a relatively large anthropogenic landcover footprint in their catchme
         nts show signs of pollution in the form of higher concentrations of nutrient
         s and dissolved ions. We find significant relationships between crop and urb
         an land cover metrics and selected water quality metrics (<em>i.e</em>. cond
         uctivity, phosphorus and nitrogen) across our data set. These results reflec
         t a very high-quality waterscape exhibiting some hotspots of degradation ass
         ociated with specific human activities. We anticipate that as agricultural i
         ntensification, urbanization and future hydropower development continue to a
         ccelerate in the basin, the number and extent of these hotspots of water qua
         lity degradation will grow in response. There is an opportunity for governme
         nts, managers and industry to mitigate water quality degradation <em>via</em
         > investment in sustainable infrastructure and practice, such as wastewater 
         treatment, environmental dam operations, or riparian protection zones.' (1894 chars)
