Catchment landscape and seasonal hydrology driving water quality in community-managed fish spawning sites of shallow Lakes Chilwa, Chiuta and Mpoto Lagoon in southern Malawi
Listed in Teesside University Research Data Repository
This dataset provides a comprehensive, multi-variable assessment of the environmental conditions within community-managed fish spawning sites across three shallow tropical waterbodies in southern Malawi: Lake Chilwa, Lake Chiuta, and Mpoto Lagoon.
Description
The data was collected to quantify the dual influence of overarching catchment characteristics (land use and hydrology) versus localized spatial protection on the water quality of vital inland fisheries.
The dataset encompasses two distinct hydrological periods: the wet season (February 2024) and the dry season (November 2024). It contains in situ water quality readings collected via multi-parameter sondes across six designated spawning sites (categorized as protected sanctuaries or unprotected zones). Core water quality parameters include temperature, dissolved oxygen, pH, turbidity, electrical conductivity, chlorophyll-a, and dissolved nutrients (nitrates and phosphates).

And this dataset also provides site-level catchment predictors derived for a 5-kilometer buffer around each spawning site. These spatial metrics include Land Use and Land Cover (LULC) changes (specifically agricultural expansion, bare soil, and dense vegetation/forest cover), estimated local population densities (WorldPop 2020), and seasonal rainfall totals. This multi-tiered data structure allows researchers to independently model variance partitioning, assess the efficacy of localized spatial closures in buffering against environmental degradation, and explore the overarching impacts of agricultural runoff and seasonal evaporative concentration in endorheic lake systems.
