Farming fish in closed containment secure tanks is steadily advancing as a more sustainable method for enlarging the supply of fresh fish needed to meet the increasing consumer demand around the world.
Combining fish culture with plant production allows us to grow much more nutritious food in much smaller spaces than traditional agriculture. This process known as Aquaponics is playing an ever increasing role in food farming.
Innovative farming techniques such as Aquaponics can be conducted in places far from traditional farming land areas. A recent story on the Living it website provides good insight into some of the operations that have developed in London.
Consider scoffing lettuce grown only in water and the effluent of fish. What about dining on mushrooms sprouted from a pile of used coffee grounds or coriander cultivated 12 storeys below the city street? These are just some of the novel growing techniques now being pioneered by London’s urban farmers.
Scientists at University of California Berkeley have revealed in journal The Scientist that the earth’s soil resources are being depleted faster than the nutrients are being replenished.“We have reached the limits of the planet. We have nowhere else to go, so we are up against natural boundaries,” says Ron Amundson, professor in Berkeley’s Department of Environmental Science, Policy and Management.It’s an imbalance that must be fixed to secure food security over the next century.
But agricultural initiatives on a commercial scale are still lacking in London.
