THE International Mother Earth Day, observed every year on April 22, is in many ways an acknowledgement that we are entirely reliant on everything that happens on Earth, and, therefore, we need to make sustainable contributions that strengthen our relationship with the planet we inhabit. But, is a single day enough to do the job?
When we look around, there is no doubt that nature is suffering right now. The swift transformations occurring within the Earth’s system are eroding essential life-sustaining processes, resulting in noticeable repercussions for society. A stark warning has been issued by the Intergovernmental Panel on Climate Change, highlighting the imminent risk of potentially catastrophic tipping points for the humanity at large and the planet’s ecosystems.
The current situation necessitates the adoption of innovative approaches to deal with the complexities of climate change. In response to this pressing issue, a comprehensive and novel paradigm, known as ‘Ecosystem Restoration based on Nature-Based Solutions’, has emerged. It encourages sustainable development by fostering a symbiotic interaction between humans and ecosystems. Its fundamental goal is to restore and preserve ecosystem health and functionality in order to ensure the sustained provision of ecosystem services, which in turn supports human wellbeing.
The preservation of current mangrove ecosystems is among the greatest examples of ecosystem restoration based on nature-based solutions. The intertidal zones, which are the areas between the land and sea borders, of estuaries, salty backwaters, deltas, creeks and lagoons are home to mangroves that are coastal wetland forests.
These plants, which include halophytic trees, shrubs, palms and ferns, are essential to the ecological stabilisation of the coast because they reduce the negative effects of wind and wave activity on the coastline, and serve as strong defenders of inland structures. In addition to being the primary natural solutions for climate change, they sequester more carbon than other blue carbon ecosystems. The estimated annual sequestration of carbon by mangrove plants and the surrounding mangrove sediments is 22.8 million metric tonnes.
Pakistan has also taken the lead in restoring mangroves on around 1.5 million acres in the Indus Delta, an ecologically significant area, through the Delta Blue Carbon project, which began in 2015. This project is unique in that it makes use of the natural ecosystem’s inherent power that combines restoration, conservation and sustainable develop-ment, providing a flexible means to strike a balance between social advance- ment and environmental preservation.
There are already almost two billion mangroves planted there, and by 2075, the project plans to have 500 million fully grown mangrove trees that are expected to absorb 262 million tonnes of carbon gas emissions. Mainstreaming community science, developing expertise in specialist domains, such taxonomy and ecosystem engineering, efficiently gathering, curating and disseminating environmental data, and putting inclusive co-management models into practice are still required for sustainable mangrove management.
Additionally, more successful stories need to be generated and propagated by establishing urban green spaces and taking sustainable agricultural practices into consideration in order to pave the way for a perfectly harmonious coexistence with our beloved planet.
