The aquaculture practice in the southwest coastal area is traditional; however, a rapid expansion of shrimp culture took place at the advent of commercial shrimp cultivating due to higher economic returns.
Shrimp cultivating is one of the few options for the economic development of the coastal region of Bangladesh.
The aquaculture practice in the southwest coastal area is traditional; however, a rapid expansion of shrimp farming took place at the advent of commercial shrimp farming due to higher economic returns.
It is a potential adaptation option for increasing salinity and other environmental stresses. The government has also promoted shrimp as a necessary climate change adaptation option in its national climate policy.
However, extensive shrimp cultivating is more likely to keep ecosystem harmony with dynamic balance by recycling and feedback mechanisms. Therefore, shrimp farming is also being considered a potential adaptation option to increased salinity in this region.
Since the shrimp sector of Bangladesh includes more than 15 million people and the majority are small-scale farmers. However, the government is yet to establish well-structured institutional support to promote sustainable shrimp farming in southwest coastal Bangladesh.
So, this natural and unsystematic shrimp cultivating is gathering impressive discourse because of its negative ecological results.
Environmental effects like mangrove destruction, sedimentation, saltwater interruption, loss of biodiversity and contamination are the obstructions to the sustainable shrimp cultivating.
A large number of lands of terrains in the seaside territories included under shrimp cultivation. Unplanned and haphazard growth of shrimp culture influences the coastal ecosystem.
Is there any way to move towards a sustainable aquaculture system for shrimp?
In sequence for aquaculture strategy to shift inside the heading of sustainable yield, the industry needs few conditions to grasp and tackle the complete spectrum of environmental effects by its operations.
Consecutively, this infers shifting near closed production frameworks.
However, unregulated coastal shrimp farming has emerged as the most unfavourable resource use over the past couple of decades in Bangladesh.
Resources like feed, seed, and water supply influence the sustainability of shrimp aquaculture. In any case, it is anything but a maintainable sort of aquaculture. However, it is not a sustainable kind of aquaculture.
A management system equally for eco-friendly and socially appropriate farming is a burning issue around the world. The long-haul advantages of shrimp farming can look for the improvement of ecologically viable shrimp farming.
It will handle the ecological and financial issues produced by a sustainable method for shrimp farming.
Why we need nature-based solutions to bridge the gap between profit and conservation?
Like Selva Shrimp, we may combine small-scale farming with active nature conservation, thereby creating livelihoods for local communities while reviving heavily degraded ecosystems.
It may improve the aquaculture practices in marginalised areas and encourages the restoration and conservation of mangrove ecosystems.
It may generate resilient local livelihoods, small-scale business alongside healthy ecosystems, a source of income, and an inclusive economy based on nature-based solutions.
It is a unique nature-based solution to protect the mangrove and aquaculture.
A nature-based solution and aquaculture with the active measure are protecting the mangrove. It is not just producing food sustainably – it is creating jobs and protecting livelihoods, too.
Mangrove reforestation, as a nature-based solution, is critical for the environment, business and people. However, a close partnership between successful private-sector seafood companies and conservation champions opens the door to transformational shifts.
Example of a nature-based solutions approach can make sure that this is the case.
A combination of nature-based solutions and aquaculture is Selva Shrimp, a program by Blueyou Consulting. First launched in VietNam, the project combines small-scale farming with active measures to protect the environment. This way, it is not just producing food sustainably – it is creating jobs and protecting livelihoods, too.
Backed by the IUCN’s Blue Natural Capital Financing Facility, Selva Shrimp is piloting the inclusion of nature-based solutions into shrimp farming in Indonesia to meet the growing appetite for consciously produced seafood. The effort aims to demonstrate the financial sustainability of such projects and their attractiveness, to show the world a path towards rectifying negative impacts generated during decades of unsustainable farming practices.
Every shrimp needs to grow with mangroves.
Moreover, it ensures incentives for farmers to change existing practices. Among these are substantially increased harvest sizes through improved farming practices and healthier environments, and a higher price for this premium product harvested mangrove areas reforested with young trees.
Similarly, the forests remain a livable habitat and food source for many other aquatic species, including crabs, oysters and mudskippers.
Mangrove forests are critical to the economic and food security of many coastal communities. They also provide a defence against floods and storms and have a crucial role in sequestering carbon from the atmosphere.
It offers extensive benefits.
The benefits of initiatives like Selva Shrimp can spread a wider than just those tending the shrimp farms, providing additional employment throughout the economy.
Farming shrimp without antibiotics, feed or chemicals produces an organic product that commands a premium price on world markets – and the additional revenue generates employment, creating jobs for some of the poorest people of the world.
