abstract = "{Freshwater ecosystems are among the most threatened on Earth, facing
environmental and anthropogenic pressures often surpassing their
terrestrial counterparts. Land use and land cover change (LUCC)
such as degradation and fragmentation of the terrestrial
landscape negatively impacts aquatic ecosystems. Satellite
imagery allows for an impartial assessment of the past to
determine habitat alterations. It can also be used as a
forecasting tool in the development of species conservation
strategies through models based on ecological factors extracted
from imagery. In this study, we analyze Landsat time sequences
(1984-2015) to quantify LUCC around three freshwater ecosystems
with endemic cichlids in Tanzania. In addition, we examine
population growth, agricultural expansion, and climate change as
stressors that impact the habitats. We found that the natural
vegetation cover surrounding Lake Chala decreased from 15.5\%
(1984) to 3.5\% (2015). At Chemka Springs, we observed a
decrease from 7.4\% to 3.5\% over the same period. While Lake
Natron had minimal LUCC, severe climate change impacts have been
forecasted for the region. Subsurface water data from the
Gravity Recovery and Climate Experiment (GRACE) satellite
observations further show a decrease in water resources for the
study areas, which could be exacerbated by increased need from a
growing population and an increase in agricultural land use.}",
