Project Impact

This project has an immense positive impact on local communities, biodiversity and the environment. It supports a number of local species, such as the Comb Duck, African Bush Elephant and Aardvark, who rely on the mangroves for food and shelter. In addition, the project provides a range of employment opportunities to community members, and for every 10,000 trees planted, 20 work days are created for local community members. The carbon reduction of the project has proven to be significant, with an estimated 0.31 tonnes of CO2 sequestered per tree.

What is Mangrove restoration?

Mangrove restoration is the process of revitalising and improving mangroves - coastal wetland habitats mainly found in tropical regions with unique trees and plants. Mangroves are crucial ecosystems for a variety of wildlife, stabilising the coastline to prevent the land from erosion and absorbing large quantities of carbon emissions to fight climate change.

The need for mangrove restoration arises due to significant damage and destruction of mangrove areas through urbanisation, aquaculture, and deforestation. Globally, between 20% and 35% of mangrove areas have been lost since 1980. This has resulted in poorer quality of life for coastal populations, lower economic growth and impoverished livelihood. Key aspects of mangrove restoration include replanting mangrove species in areas where they have been depleted or destroyed, restoring local ecosystem dynamics, involving communities in planning and implementation, and implementing protective measures.

Mangrove restoration is essential not only for the preservation of biodiversity and ecological balance but also for the well-being of coastal communities that rely on these ecosystems for their livelihoods. It contributes to the overall health of coastal environments, enhances fisheries, promotes sustainable practices, and mitigates the impact of natural disasters.

Mangrove restoration in Kenya

The Coastal areas of Kenya rank among the country’s lesser-developed regions. The livelihoods, employment and nutritional needs of these communities heavily rely on mangrove ecosystems. Over the past few decades, Southern Kenya’s coastal regions have experienced rapid urbanisation, leading to the conversion of mangrove forests for alternative land uses. Additionally, inadequate governance has contributed to the overexploitation and excessive harvesting of mangroves.

The key objective of EarthLung’s Mangrove restoration project in Kenya is to uplift financially disadvantaged coastal communities by revitalising the mangrove forests aiming to ‘break the cycle of poverty’. Through the restoration of the biodiverse estuary, this initiative will not only establish new fishing grounds but also generate supplementary sources of income. Moreover, the rejuvenated forests will serve as a protective barrier against storm surges.

While in the right conditions propagules are directly planted on site, in other conditions, they are nursed in a nursery until conditions are right to plant on site.

The process of Mangrove restoration

The two main methods of mangrove planting are nurseries and direct planting. Nurseries nurture seedlings until they are ready for permanent planting in the wild, providing better growth rates and higher survival rates. The community in the nursery can produce up to 300 pots daily, collecting propagules and planting them. The nursery process involves filling bags with muddy and clayey soil, germinating seeds, and nursing plants with watering, shading, weeding, pest control, fertilization, and hardening.

The second method is direct planting, where the team pick propagules off existing trees and plant them directly.  Both methods are challenging and often require an early start and a late finish. Accessing planting sites can be physically demanding, involving trudging through mangrove channels in hot, knee-deep mud, often barefoot due to the swampy terrain. Planting partners navigate through extensive mangrove roots. At the planting site, approximately 5,000 propagules are planted per hectare, roughly one propagule for every two steps, inserted up to one-third of their length. Planting and protection methods are well planned, resulting in a healthy survival rate of saplings of roughly 80%.

UN Sustainable Development Goals contributed to

The United Nations Sustainable Development Goals (SDGs) are a set of 17 interconnected global objectives aimed at addressing pressing social, economic, and environmental challenges by 2030. They serve as a blueprint for collective action, guiding governments, businesses, and communities worldwide towards a more sustainable and equitable future.

Verification

This project uses site technology, including Dendrometers, Soil Sensors, Bioacoustic Sensors, Light Sensors and weather stations, to ensure accuracy and precision in measuring impact. The process of measurement, reporting and verification starts with evaluating the size of the land targeted. Collecting and monitoring data on trees planted within the region. Verifying and publishing the data collated and then visualising and amplifying this through reports on the number of trees planted, hectares reforested, CO2 sequestered and work days provided.
