Tanzania climate adaptation adds mangrove and coral reef restoration to urban seawall

On June 5, 2018, the Vice-President of Tanzania, Samia Suluhu, gave a speech in Dar-es-Salaam to mark the completion of a large-scale sea defense project along the country’s coastline.

Besides a new urban seawall, the project included the rehabilitation of approximately 1,000 hectares of mangrove habitat across Tanzania’s coastline. Up to 2000 square meters of coral reefs were also restored.

Climate change has already led to increased temperatures and rising sea levels in this East African nation. Without major investments in adaptation, an annual average of 800,000 Tanzanians stand to be impacted by flooding caused by rising sea levels between 2070 and 2100. Around five million people currently live in Dar- es- Salaam, a coastal metropolis at risk of flooding.

Vice-President Suluhu remarked: “The effects of climate change pose huge challenges to the people of Tanzania…through the construction of these walls in the various parts of the country, we see the importance of the project. Kisiwa Panza (northern Tanzania) was sinking but now the residents are living well and in peace. We’ve also prevented Pangani from effects of erosion…We thank the United Nations for their support.

The United Nations Office for Project Services (UNOPS) and UN Environment worked with the Government of Tanzania to increase the resilience of coastal areas against the impacts of climate change and rising sea levels.

A warmer ocean and rising sea levels threaten the way women, men and children live along the world’s coasts. There is no question that we must work together to help our most vulnerable populations cope with an uncertain future. Our efforts with the Government and UN Environment to increase the resilience of Tanzania’s coastal areas shows that model in action,” said UNOPS Executive Director Grete Faremo.

With financial support from the Adaptation Fund, the Least Developed Countries Fund, and the Government of Tanzania, seawalls were constructed in seven sites along Tanzania’s coast.

UN Environment Executive Director Erik Solheim said the reality of living with a changing climate is already upon us. “It’s now time to start adapting to a warming world and many countries are realizing this. Climate change hurts the least protected, and as sea-levels rise, adaptation projects like this seawall are vital. They demonstrate what we can accomplish when we bring together the expertise of UN Environment with the efficiency of UNOPS.

The project was part of a broader UN Environment initiative to build climate resilience by improving natural ecosystems. As such, the seawalls were accompanied by the restoration of mangrove and coral habitats, both of which act as natural barriers against wave and tidal surges.

The defense structures allow communities in low-lying areas and informal settlements to continue income-generating activities, such as fishing and agriculture. Solar-powered street lights and benches have also been installed along the seawalls.

The seawall inauguration ceremony took place on the last day of a week-long event in Tanzania, designed to commemorate World Environment Day and raise awareness on environmental issues in the country.
