Given
the fragility of wetlands, their importance for water supply and the growing
pressures to convert them to agriculture uses, there is an urgent need
to try to achieve sustainable use of wetlands. This requires management
regimes which help maintain some of the natural characteristics of wetlands
while also allowing partial conversion to allow activities which can meet
the economic needs of communities. A balance has to be struck between
the environmental functioning of wetlands and their use for livelihood
purposes.
Sustainable
Wetland Management – some factors to consider
Sustainable
wetland management regimes are found in various situations. Usually they
involve minimal conversion of the wetland and limited degradation of the
catchment. However, more interventionist regimes can be found which are
sustainable where more complex water management regimes are applied.
In
all cases sustainable
management involves some form of multiple-use regime, with a particular
pattern of land use in the wetland and catchment being vital for sustaining
wetland functioning. The
experience of this has been documented in many parts of Africa by CWEL
staff and other researchers, and several CWEL projects are in progress
seek to test the wider applicability of these methods. Overall, it is
clear that an integrated wetlands and catchment approach is needed, seeing
these two elements as linked parts of the landscape.
