Seawater Farming

The UN says there is less than a decade to avoid a climate change catastrophe

One of the largest contributors to climate change is the agricultural sector; it is also the sector that is experiencing greater climate disruptions, and that must innovate to support a growing population.

  •  75% of land worldwide is used for agriculture 
  •  33% of Earth’s land is being severely degraded due to harmful agricultural practices 
  •  25bn tonnes of fertile soil being lost a year 
  •  1.5 billion people will be directly affected by land degradation 
  •  $490 billion per year to support affected communities 
  •  7% of the total European agricultural land is lost each year 
  •  €1.25 billion annual agricultural productivity reduction 
  •  97% of Earth’s water is saltwater 
  •  70% of Earth’s freshwater is used for agriculture 
  •  19% predicted increase in water demands for irrigational needs by 2050.

This situation cannot continue.

The Opportunity

Seawater Solutions champions climate resilience by rethinking farming and equipping farmers with systems that tackle the challenges of climate change. Our aim is to promote sustainable agricultural innovation, environmental promotion and rural development, whilst pursuing the sustainability development goals from the United to discuss further.

Sea vegetables represent a multi-million GBP market, and one which is expected to grow 8-10% annually. We offer our partners:

  • High-value ‘superfoods’ (such as Samphire) for domestic and international markets
  • Increased incomes in a context of diminishing market returns
  • Increased yields and soil health
  • Support moving towards organic, no-tillage and regenerative farming practices
  • Promotion of wildlife through ecosystem restoration/creation 
  • Defence of their coastlines from rising sea-levels
  • Significantly increased carbon capture potential of their land.
Artificially created or restored wetlands actively improves the health of the local ecosystem; protecting it from potential industrial or agricultural discharge, encouraging habitat and species restoration, protecting the land from water incursion and soil run off, plus storing vast amounts of carbon. Find out below about all the possibilities that seawater farming opens.

Salt-tolerant Crops

Seawater Solutions are the first operation in the UK to grow halophytic plants on farmland. In fact, we are the first in Europe to redevelop farmland to introduce wetland ecosystems, and artificially introduce seawater. Over the next three years we aim to introduce 30+ salt-tolerant vegetable species for various products. Our focus for these saline crops is for consumption towards a rapidly growing sea-vegetable market that is hungry for organic, nutritious, and environmentally-promoting produce. Samphire has gained a reputation as a “superfood” with astounding nutritional value, including Omega 3, high levels of iron, and the highest linoleic acid content of any crop. Find out more about our salt-tolerant crops

Whether you are a shrimp farmer in Vietnam or a landowner on the Scottish coast, diversification of your portfolio provides financial resilience in uncertain times, as well as important environmental services to your land and operations. 

Seawater farming provides such resilience. Here are just some of the ways that we can help you to expand your portfolio:

  • Growing new crops on redundant or degraded land for sale at market or for use in-house (from on-site restaurants to flavourings in your primary products)
  • Exploiting carbon capture credits
  • Allowing animals to feed on salt-tolerant meadows (providing important nutritional supplements for healthier animals, as well as increasing the rarity and value of the meat produced)
  • Exploring halophyte by-product potential.

There are no other companies operating sites around the world with the aim of commercialising wetland restoration and aquaculture farming for financial and environmental gain. We hold unique expertise in this area, having successfully launched the UK’s first seawater farm, and we advise companies and individuals as to the benefits and requirements for creating their own wetland restoration or aquaculture projects.


Our mission is to share knowledge and expertise so that communities around the world can benefit from regenerative farming approaches, to help clean the planet and provide economic and personal resilience. Time is running out and the global population is growing – working together we can help transform agriculture for future generations.

Salt-tolerant crops, also known as halophytes, are amazing plants. Not only do they grow in extreme environments to create a highly nutritious superfood, but they also have significant potential for by-product cultivation, including: ​

  • Natural salt substitutes produced from saline plants with high potential in health industries
  • Oils for cosmetics, such as linoleic acid used in skin-care products
  • Biofuels, with high potential for cultivation in concert with our planned operations in Bangladesh
  • Sea-plant animal fodder has immense potential globally with various saline crops proven to improve animal health, and is a sustainable alternative to imported feed
  • Carbon Credits for environmental and CSR initiatives – find out more about how we are creating wetlands to support carbon capture

Seawater Solutions are currently exploring these and more options, and keen to hear from individuals or companies who would be interested in collaboration.

Our Integrated Seawater Farming System has redeveloped degraded land on the West Coast of Scotland into artificial wetlands to increase the value of the land, protect it against soil degradation (and soil salinization), capture carbon and eliminate chemical contamination.


All the while growing high-value “superfoods” vegetable without using a single drop of freshwater – an unexpected issue in Scotland but according to the farmer they have needed to extract more groundwater to irrigate the land in the last 2 years than the previous 8 years. 

​“We’ve taken a piece of land here that was maybe only going to yield a couple of hundred pounds per year into something that could maybe yield a couple of thousand pounds per year,” Jay Crawford, Partner and owner of Dowhill Farm.

Sustainable, regenerative agriculture

We are the first in the UK to grow food with seawater, and our pilot farm is an innovative model for the future of sustainable agriculture. Our specific farming methods are environmentally-promoting systems, due to the sheer agricultural and environmental benefits they deliver. They equip farmers with the tools for climate resilience and an opportunity to diversify their operations in a context of uncertainty in agriculture.

Our system uses solar and wind-powered irrigation systems to deliver seawater into coastal farmland. Our fields are redeveloped to optimise waterflows and improve the efficiency of our irrigation systems, mimicking the natural tidal saltmarsh ecosystems to which these species are native. These crops, including Samphire and Aster, are specially bred to suit the specific land requirements of each farm.
