The Impacts Of Local Communities Enchroachment On Wetland Ecosystem; A Case Study Of Tana River Wetlands In Tana River County, Kenya

ABSTRACT

The study investigated the impacts of local communities’ encroachment on wetland ecosystem

using Tana River wetlands in Tana County, Kenya. The main objective was to find out the

activities of local communities that are responsible for Tana River wetland degradation. The

problem in the context was because many people have considered wetlands as useless or waste

lands, there has always been drained or reclaimed, filled in or used as dumping grounds yet

wetlands play very important roles such as maintaining water cycle, control of floods, nutrient

retention and export hence Wetland ecosystems have been threatened extensively, especially the

lowland valley wetlands and swamp forests are coming under pressure.

The results of the study revealed that Human communities, especially those living in and around

Tana River Wetlands, often have important and long standing relationships/benefits with the

wetlands. The rate of encroachment on to the wetland is increasing further than the wetland

regeneration of its resources and unless intervention measures are deployed, the local community

activities will continue causing degradation and depletion of the wetland resources. The activities

in question included cultivation/digging, brick making, fishing on river Tana, and sand mining.

Currently, these activities have doubled to extend beyond the boundaries of the catchment

wetlands of river Tana and its banks due to increased human population pressure. The major

activities in Tana River wetlands responsible for degradation included nomadic Pastoralism

which is 56%, other activities include, burning of wetlands which is 20%, grazing animals 10%

and cultivation of land 5%.

In a nutshell, the measures identified to control effects of burning grasslands included 1and~based

system as a way of detecting instances of fires, another way was through backfiring already used

in some parts of Tana River region. and it involves a consistent and carefully controlled method

of burning strips of grasslands, forests and other vegetation that have been subjected to fire. The

researcher recommends practices such as destocking, wetland protection associations, public

sensitizations on the values and conservation measures of wetlands and other water resources in Tana River region.
