Group revives Sabaki estuary for conservation, ecotourism

“Sabaki estuary is opening up. Visitors can now feel the beauty of this delicate ecosystem unlike before when the access was a challenge. The construction of a boardwalk is not only opening up this site but also creating opportunities for us as local communities to undertake eco-tourism activities and enhance conservation,” Mwandenge says.

Sabaki River estuary is one of the 68 key biodiversity areas in the country located at the tail end of the Athi-Galana -Sabaki river basin.

The unique ecosystem comprises of sandbanks, mudflats, dunes, freshwater pools, marshes and mangroves.

It is an important habitat for local residents and migratory shorebirds, and a home to over 240 bird species. The ecosystem is also an important nursery ground for crustaceans and fish, while its sandy shores on both sides are breeding grounds for turtles.

Different species of mangroves line their mudflats. Crocodiles, hippos, and antelopes also live in the area. 

According to Francis Kagema, Nature Kenya’s Coastal Co-ordinator, Sabaki provides suitable habitat to a variety of organisms that constitute the biodiversity of the estuary. 

“This biodiversity, if left alone, can thrive well but there are activities that interfere with the ecological processes The risk of degradation is real and has already started showing in over fishing and mangrove harvesting,” Kagema said.

But as Athi River springs up from Gatamaiyo Forest, in Kiambu County, flowing down, assuming the new name of Galana before morphing into Sabaki River along the 77,000 square-kilometer course, the river gets polluted by both solid and liquid effluent. 

It also faces a myriad of challenges around the unique estuary where land grabbing is becoming a major concern, coupled with other illegal activities including illegal harvesting of the mangrove poles, sand harvesting, and fishing with illegal gear.

To stem these growing challenges, Mwandenge and his group - which he chairs under a community conservation group known as Sabaki River Conservation Development Organisation - have been engaging in conservation activities along the estuary. 

The conservation group is one of the site support groups backed by Nature Kenya within key biodiversity areas across the country.

Often, Mwandenge and his teammates undertake conservation awareness, outreaches, beach cleanups, and monitoring of bird species within the delicate ecosystem.

The challenges, according to environmental experts, have impacted water quality, biodiversity, and vegetation, disrupting the estuary’s ecosystem.

While this conservation exercise is tasking and requires incentives for the conservation group to undertake its activities sustainably, a project being implemented by Nature Kenya through the United Nations Environment Programme (UNEP) is slowly giving a lifeline to the Sabaki estuary. 

The project is being implemented through UNEP’s Western Indian Ocean Strategic Action Programme.

The initiative has delivered facilities including the construction of the boardwalk, bird photography hide, and picnic shelter, known locally as a “banda”.

“This project came in at a time when the negative effects were becoming more rampant and stakeholders were deliberating on the next steps to undertake to save the estuary. This project aims to sustainably manage the estuarine ecosystem,” Kagema says.

Already, Sammy Kenga, a fisherman who is also a member of the community conservation group, says there has been a spike in the number of visitors accessing the site, a record he says will generate revenue to sustain conservation activities within the delicate ecosystem.

“Besides an influx of visitors, this boardwalk has also helped in combating cases of land grabbing, cases which are becoming very rampant within areas around the beach,” Kenga adds.
