1. To provide a permanent and permanently sustainable source ofpotable (drinking)water.2. To provide a manageable and sustainable source of food for thegrowing population (of 9B people by 2050).3. To provide adequate low-cost housing for everyone, helping inpopulation planning (family planning) hence raising standards of living.4. To create useful employment, especially for the unemployed peopleliving on the streets and slums.5. To fertilize soils of the vast arid and semi-arid lands and henceestablish watercatchment areas by reforestation programs and reverseglobal warmingObjectives
1. Clean filtered seawater is tapped from the ocean, 600m+ fromthe coastline and piped far inland to the Desert Farms.2. Part of the water goes into the trench-lakes while part goes tothe Desalination plants cum Housing.3. Saline-water fish is also transported from other lakes andoceans and introduced to the trenchlakes.4. Fast-growing seaweed is also transported from the ocean andgrown in the trench-lake.How? The Process:Stage 1: Transport
Takes place on triangular shaped housing structures. Inside are 1and 2 bedroom apartments while the exterior walls and the spacebetween two apartments is where desalination occurs.Stage 2: Desalination
Water overflows slowly from a tray on top of the triangular structure(a), trickling down the sides (b). Sunlight passes through the plasticone-way film and is trapped inside, heating the water (c).Stage 2: Desalination
The salty water evaporates and the moisture condenses on theinner side of the plastic, and is tapped off. Condensation takesplace because of a sheet of cool water flowing down on the outsideof the one-way plastic film.Stage 2: Desalination
Excess water drains out to the evaporation pan between the twohousing apartments, and is evaporated to dryness and watercollected.Stage 2: Desalination
The desalination housing units are oriented in the general directionof the sun, and receives maximum solar radiation between 10 and 2.Stage 2: Desalination
1. The land is watered with slightly diluted saline water and salt-resistant grass grown, e.g. Pemba grass.2. Slowly lowering salinity, different types of grasses are grown andcut repeatedly mixed with cow dung forming compost, which when mixed with sand, produces a thin layer of topsoil. Seaweed harvested from the beaches can also be added to provide nutrients and act as mulching, reducing evaporation rates of water nearthe roots.3. A border of trees is planted to act as windbreaks and a source ofshade for the plant nurseries.Stage 3: Land Reclamation
1. The fish from the lake are bred and serve as a source of food.(Fish farming).2. The seaweed provides shade for the fish, and also provides agrowing source of soil compost/manure to grow crops on. It alsoacts as good mulching when wet, and a source of biogas forcooking when mixed with cowdung and fermented.3. Plant and tree seedlings are nurtured on the leeward side of thelong lake. Behind the nursery is the farm, protected with treewindbreaks.Stage 4: Farming
This project does not ignore the fact that vast amounts of waterin arid areas is wasted as surface run-off.Therefore, the outside surface of the desalination housing unitshave channels in which rainwater collected from the walls ischanneled and stored.Also, channels are dug in the ground to encourage floodwaterto go into separate empty trench lakes to act as reservoirs.Stage 5: Rainwater and Surface run-offHarvesting
Stage 5: Rainwater and Surface run-offHarvesting
1. One acre of desalination housing produces upto 10650litres of distilled drinking water every day per acre of land, worth 132,000ksh (or 1550 US$) at current market price, for FREE. This is enough to sustain at least 200 people at 50 liters each, an improvement from the 5 liters an average African gets daily after struggle. Ifthis distilled water is dedicated to drinking and cooking only, around 20litres per person, the number who can live on this climbs to528 people! This improvement from the 5 liters an averageAfrican gets daily after struggle.Statistics and Figures.
2. The trench lake is 9million litres capacity, 4m deep, 6m wide attop, and 450m long. Needless to say, thats a LOT of fish, seaweedand water. This can comfortably be a source of food-protein,especially in communal catering.3. On the same acre of desalination is the housing structures whichcan support upto 60 single child families (180 people), or 114singles (114 people)Statistics and Figures.
This project is based on the module system, one module consisting ofa desalination housing unit, a trench-lake, a farm and a reservoir tank.Upon obtaining more resources, another module can be added and waterfeedline obtained from the main pipeline from the sea. Expansion is readilyand easily undertaken.The project, since it addresses the issue of low-cost housing, can beimplemented practically everywhere, in schools to be residentialdormitories, in villages etc.Therefore our future vision is to see the first desert city beingdeveloped, overtaking the current city projects ‘Tatu’ and ‘Konza’ in Kenya,not as a technology city, but a green city.Future Vision
FAQ (Frequently Asked Questions)1. What are people living in the houses provided with?A bed, cupboard, table, shelf, sofa, 3 chairs, washbasin.2. What are the other buildings available in the desert city?A library, hospitals, community centre (drama stage, traditional wrestlingarena), schools, playground/football field, religious centres (church, mosque,temple).3. What jobs will the unemployed people shifting to the farms get?Besides the main agricultural aspect, people will be needed for maintenance of the different sections, transporters, builders, casual laborers, engineers,and many more. All types of people will be needed since this project is a holisticone.4. What form is their remuneration?This can be open to the prevailing demands and situations. Various options consist of discounted housing, water, food, schooling, health, etc.
FAQ (Frequently Asked Questions)5. How will you get the seaweed to the lake you have created?Using the highway, several tankers (or decommissioned petrol tankers)are driven to the site with seawater and live seaweed inside them. The seaweedis then dumped with the seawater into the trenchlake and once the seaweedcultivation is started, once every 3 months a new species of seaweed or freshsupply can be brought. In the beginning of the project, dead seaweed depositedon to the beach can be brought in to the farmsite to start off the reclamationprocess as fertilizer.6. How much money will it take to build a desert farm, and a desert city? Feel free to give statistics and figures.A good part of this project involves low cost materials which shouldbring down the full cost by a significant margin. A trial project with the 1000US$should cover the cost of all materials (79800ksh/938US$), while labour will beprovided by our team members, and the land by our university.
FAQ (Frequently Asked Questions)7. How will you go about funding the building of this desert farm and city?We shall, with your help, earn the funding from Thought For Foodfoundation and construct a working model of 10 modules, after which we shallapproach various stakeholders in the market such as water pump manufacturers,contractors, architects, cement manufacturers, farmers, machinery builders, etc tostart a joint venture capitalist project, except this will be a part of their CSR(Corporate Social Responsibility).8. How long will the above city take to build?Once the designs for the module are sent, shop drawings approved, themanufacture of the parts should take less than a week. Assembling them andcommissioning will take another week. Therefore, assuming we have to go smallscale, a single module, it will take us no more than 2 weeks. If we plan to build more,government permits and other legal matters aside, the rate should drop to 6days permodule. If we hire workers and machinery, 10 modules can be made every 6days,hence in a year, we can finish 520 modules (settling 1560people a year!)9. What species of trees does this project aim to plant?We plan to introduce coconut trees (since they do well in sandy soils withsome percentage of salinity in the water). Jatropha and other hardy bushes too, sinceJatropha is an excellent source of oil which can be best used to manufacture soap forsale(economic activity).
FAQ (Frequently Asked Questions)10. How do you plan to get these trees ready by the end of the creation of the farm?We plan to use a concept called extended nursery system, where we plant these trees a few years before the beginning of the project into large clay containers.When the tree is nearly fully grown, we transport it to the new site, break the pot andplant the tree. Thus readymade fully grown trees can be continuously supplied.11.. What food crops will you plant?Yam, arrowroots, cassava. These can be in the initial stages to gauge theirgrowth. Later on with stabilized water production, maize, bananas, potatoes and wheat can be tried. We shall also try a range of new food crops to divert people from overdependence on staple foods.17. How is the project going to solve the problem of current unsustainable population growth?Prevention is better than cure. With looming food security crisis in future, itwould be folly to raise a large family, especially when living below the poverty line, asis the case with many developing countries, especially Africa. According to UNstatistics, the population growth rate in Africa is one of the highest, and the overallpopulation is expected to grow more than double its current size, by 2025, over1.4Billion people. Therefore, all residents of Project Desert Farms are greatlyencouraged to adhere to family planning. We see it a wise decision to bring childreninto the world only when the food and economic state of the parents is stable, hencelowering child mortality rates.
