Seawater Greenhouse

September 2018

The department of Agriculture has commenced its research on how it can introduce green Agricultural firms in Bosaso Puntland State of Somalia. The project is aimed to improve agricultural practices within Bari region and reduce instances of food insecurity.  The award-winning technology, invented by Seawater Greenhouse Ltd. founder Charlie Paton, was inspired by the natural water cycle where seawater heated by the sun evaporates, cools to form clouds, and returns to earth as precipitation.  

Problem Statement

Having suffered from food insecurity for years, Bosaso has a reason to smile after University of Bosaso has embarked on innovative technology of enhancing Agricultural production using Seawater. Even though the technology has been utilized in Somaliland, the University of Bosaso has decided to take it to a larger scale. The project will see the whole city of Bosaso full of fresh vegetables, fruits and corn.  This will not only solve malnutrition problems that result from extreme drought but will also stimulate economy in town. In addition, there are a lot of conflicts because of strained resources within the region.  The Seawater greenhouse will increase the resources that shall see everyone in the society having something to eat. Use of fossil fuel remains a major problem in the world today. Using conventional approaches like farm machineries to grow foods with this much scale would emit nearly 2 tons of CO2 in the atmosphere. This is likely to increase the rate of global warming. In addition, the ecosystem is likely to be interfered with. In order to slow these atrocious processes, a smart solution of desalination the sea remains the only option Bosaso people can use to increase their food productivity.

How the Seawater greenhouse runs

The Seawater Greenhouse aims to provide sustainable local production of food by combining a growing environment in which water usage is minimized, with a desalination system powered substantially by solar energy.  Evaporating water from the sea is usually hot and when its passes through a cool surface, it quickly cools down and forms pure water droplets. The system has proved sustainable because it’s clean and powered by renewable power from the solar. It has a honey comb evaporator which filters unrequired particles from entering the greenhouse. Other chemicals in water solution can be used to make fertilizer for the crops and the remaining salts can be made to gourmet salt. Figure 1: Credit Seawater Greenhouse  

Economic Importance

Seawater greenhouse provides and economical and sustainable solution in regions where hope for agriculture is almost despaired off. The greenhouse provides pure water that can be used for domestic consumption apart from agricultural needs which is the primary reason for its inception. It is indeed an original idea that has a potential of feeding hundreds of thousands of people not only in Somalia but throughout Somalia. One important factor to note is seawater greenhouse produces crops throughout the year. It has no seasons as conventional agricultural practices. Therefore, the economic is likely to be a continually well provided the greenhouse is running.


Seawater greenhouse like any other conventional greenhouse is costly and 1 ha is likely to cost 1 million USD to set up the sea water greenhouse. Tomatoes are widely cultivated in greenhouses. 1 ha greenhouse will produce 500 tons of tomatoes yearly. If the price is maintained at 1$ per kg, 500 tons will yield 0.5 million USD yearly.  Such revenues will significantly boost the economy of a given town and improve the lifestyle as well. Typically, the starting capital of seawater greenhouse is intensive.

Areas it has been implemented within Somalia

Seawater green house has been tested in Berbera and proved to be quite effective.


The University intends to carry out this project on its own and any other partners/sponsors that would like to join hands. The project is financially intensive but the fruits of the outcome are likely to be of good help. The University of Bosaso is currently building a model for the same and will soon publish the progress of the same.
