Using 20 years of data, state agencies have been able to track how the use of land have impacted the water quality and aquatic life in lakes and streams in the world.

Over the past 20 years, research has been done by senior scientist across the world on natural resources management and aquatic system management in particular.

In Ghana alone, more than 1.4 million acres of grasslands were converted to cropland, industrial, and mining sites. Within this landscape are surface waters that include lakes and rivers between 2008 and 2015

However, lot of things come into play, not just land use.  Accra alone, goes through cycles of drought, drainage system and flooding that affect water availability and aquatic production. This can have a more dramatic effect than climate change. The “clean water” as said provided to citizen cannot be consume and they therefore sustain on processed water only.

In some part of the world, they hope to use long-term data from water quality assessments to evaluate relationships between beneficial water uses and land use patterns. Those beneficial water uses include fish and wildlife propagation, recreation and stock watering sources, in addition to more specific uses such as domestic water supply.
