绿色波’s polyculture ocean farming method produces a mixture of shellfish and seaweeds in a nature-positive way. Their system comprises a simple 3D lattice of ropes and baskets suspended just below the surface, with different species growing at different depths. The system can be used for commercial farming of marine products that are used for food, fertiliser, animal feed and bioplastics, as well as for the restoration of marine ecosystems.
绿色波is based in Connecticut and was set up by a former fisherman called Bren Smith, who had become disillusioned with the pillage inflicted by commercial fishing on the planet’s oceans. Smith established the non-profit GreenWave to catalyse the regenerative ocean farming movement. As well as leading this, he also manages his own 20-acreThimble Island Ocean Farm,每五个月生产30吨高营养的海藻和250,000个贝类。
绿色波’s mission is to provide training, tools and other support to a network of 10, 000 regenerative ocean farmers, prioritising fishermen, indigenous coastal communities, and those directly affected by climate change. The overall aim is to plant 1 million acres (400, 000 hectares) of regenerative ocean crops in the next 10 years.
朝这个目标的进步看起来不错。目前,在等待名单上,大约有8,000人参加其海洋农场计划。
So much of the climate discussion around the ocean has focused on its role as a victim (vanishing marine species, acidification) or a threat (rising sea levels threatening lives and livelihoods), but little attention has been focused on the ocean’s tremendous potential as a tool to mitigate and even reverse the underlying causes.
Every year the ocean absorbs 90% of the excess heat trapped by greenhouse gases and 30% of the world’s atmospheric CO2, but to continue to play a role in the face of accelerating emissions, the ocean needs a little support. This is where GreenWave’s regenerative ocean farming model comes in.
再生海洋耕作不需要生产过程中的任何投入,因为海洋含有足够的营养来支持健康的生长。话虽如此,由于过量的肥料使用,沿海农田或河流河流流的风暴通常含有过量的氮和磷。再生海洋农场能够吸收其中的一些营养,从而降低了藻类富营养化的可能性和潜在的风险oceanic dead zones。
除了提供“生态系统服务”外,再生海洋农场还可以增强海洋生物多样性。农场的集会模仿了海洋礁的垂直结构,为各种海洋物种提供了不同栖息地的层。
再生3D海洋耕种的多养文学方法非常有效,因为它彼此之间堆叠了许多企业,在小区域内产生了很高的丰富。由于增长的结构相当简单,因此启动成本很低。任何拥有20英亩和船的人都可以为20,000至50,000美元建立一个农场,每年生产约60,000公斤的海带和250,000个贝类。
Oceans cover 70% of our planet but只生产我们2%的食物。再生海洋耕作提供了一种海洋生产系统的可能性,既高产,又有助于海洋生态系统的再生。
除了有吸引力的投资回报率外,还有许多与再生海洋耕作相关的其他好处,涵盖了循环经济的大多数重要特征。亚博足球分析
Seaweed and shellfish ocean farms regenerate natural systems by reducing ocean acidification and providing a habitat for a diverse number of marine species.
A typical 20-acre farm can sequester 9,000 kg of carbon dioxide and 300 kg of nitrogen in one year.
海藻是一种营养成分,含有大量的omega-3,钾,铁,钙和纤维。现在,许多厨师和其他食品设计师正在积极采购营养和nature-positive。
Regenerative ocean farming is a tool for climate adaptation. Large floating masses of aquatic plant life absorb the energy of storm surges, reducing risks to coastal communities.
According to the World Bank, farming seaweed in just 0.1% of the world’s oceans could create 50 million direct jobs, and a further 100 million associated jobs.
扩展的潜力是巨大的。世界经济论坛估计,如果每年海藻产量增加14%,到2050年,它将将全球粮食供应增加5亿吨,相当于10%。
Despite the potential of the ocean farming approach, there are a number of obstacles that new farmers face in developing their business:
Securing the required permits can be a bureaucratic process involving numerous state agencies as well as overcoming the nimbyism of coastal villa owners.
识别适合农场的位置会带来许多物理参数。Greenwave最近与国家海洋与大气管理to deploy cutting-edge sensor technology to help model and predict optimal sites.
作为相对利基的产品,基础设施对于海藻和海带的大规模加工没有就位。SEA Grant网络最近建立了National Seaweed Hubto act as a support institution for the nascent industry.
To increase demand GreenWave has set up a buyer’s network that stretches from New York to Maine. A partnership with the Crop Project, a NY based first-stage processor, led to a 400% increase in sales.
Raw kelp has a limited shelf-life, it needs to be harvested and processed within a small window of time. Local processing plants would help address this. GreenWave is also working with the US Department of Agriculture to develop innovative fresh packaging technology and shelf-stable products to further increase farmer opportunities.
