Why conserve wetlands?
Wetlands are among the world's most productive environments. The interactions
of physical, chemical and biological components of a wetland enable it
to perform vital functions in ecosystems and the well-being of human communities
in general.
Ecological value:
They are cradles of biological diversity supporting countless species
of plants and animals, in particular waterfowls, by providing food, breeding
and nursery grounds.
Functional value:
They also perform vital functions including water storage, flood control,
erosion control, shore stabilization and water purification through retention
of sediments and filtering out pollutants, climate stabilization etc.
Economic and amenity values:
Wetlands provide economic benefits, for example, fish farming in aquacultural
ponds and wet agricultural activities. They also provide recreation, amenity
and landscape opportunities.
