The Buried Diffuser for Climate change and drought mitigation

Drought is actually a worldwide problem: in poor countries as well as in rich countries. USA is considered as the top developed country in agriculture with high technical and scientific level. But What USA and other developed countries (Europe, Japan, etc.) could not control is drought and flood.
Drought and flood are facts everywhere in the Globe: in arid, semi arid régions, in humid regions and regions getting more then 1000 millimetres (40 inches) rainfall per year. Man can not change the climate and stop tornadoes, heavy rains and floods, and stop droughts.

We have to review our behaviours toward water resources and review our existing technologies which contribute in the lost of the fossil water tables. Just one example: the big circles producing cereals in the desert conditions, in many countries worldwide (USA, Algeria, Arabia Saudi, Australia etc.), using pivot irrigation technology, is a real catastrophe. We have also to find new ways and methods to “cooperate” with Exceptional heavy rains and with Droughts (short seasonal drought and long 2 till 3 dry years.).The Exceptional heavy rains cause dramatic floods even in USA. This huge of water, after causing disasters, is lost in the oceans, seas and salt lakes, in the desert. Is It possible to avoid the disasters and water lost during the Exceptional heavy rains and store billions of cubic meters in the soils and in the underground water tables?

For storing the rain water in the underground water tables, the technology exists. We have to use it more and more. But storing the water in the soil to mitigate short term and long term drought is something New, New, New. This new concept has been validated in Tunisia, a semi arid and arid North African country. This new concept includes: “the anticipated irrigation using buried diffusers” and “the Water Injection and storage in the deep soil layers, using buried diffusers”

The “anticipated irrigation using buried diffusers” is: Instead of irrigation during the hot or the dry season, the irrigation using Buried Diffusers is done during the autumn and winter or during the rainy season. The amount of water of the “Anticipated Irrigation” should cover the total need of the crop during the hot or dry season (spring and summer). This water amount is stored in the deep soil layers will be used by the deep or sub surface roots systems of the crops. This“anticipated irrigation using buried diffusers” is still in use in Tunisia and will be transferred to Arabia Saudi, Morocco, Kenya, Nigeria and many others countries. The experimentation on cereals (wheat, corn, sunflower, etc.) of this “anticipated irrigation using buried diffusers” is programmed during 2014.

The “Water Injection and storage in the deep soil layers, using buried diffusers” is useful especially for trees crops. The injected water comes from: dams, rivers, and springs. The amount of the injected water could cover the need of the trees for several years (2 to 3 years) when the soil below 50 cm is thick (1 meter or more) and contains minimum 10% clay. This injected water is conserved (stored) in the deep soil layers (50 cm below the soil surface) and used later by the deep root systems of the trees during a short or a long drought period: six months till 3 years. During the drought, the trees produce normally using the injected and stored water. This“Water Injection and storage in the deep soil layers, using buried diffusers” is still in use in Tunisia and will be transferred to Saudi Arabia, Morocco, Kenya, Nigeria and many others countries.

Chahtech is seeking states, countries, international organisations (FAO, UNDP, UNEP, IFAD etc.) and NGOs to transfer this technology, there where there is problem of drought, food security and hunger.

CHAHTECH in The Kingdom of Saudi Arabia

CHAHTECH, Water Efficiency France and Delta Water Efficiency, responsible for marketing the Buried Diffuser in the Arabian Gulf countries, made a series of demonstrations at several agricultural groups specialized in the production of dates and olive oil. This successful operation will be followed by large-scale installations of Buried Diffuser.
Farm managers, aware of issues related to water management, wish to join the Buried Diffuser not only as a conventional irrigation system, but rather as a revolutionary methodology for optimal water management (Anticipated Irrigation and Injection of water in deep soil layers).

CHAHTECH in Morocco

CHAHTECH and its partner WWS, responsible for marketing the Buried Diffuser in Morocco, were present at the International Agricultural Fair in Meknes (SIAM) and Water Expo and Forum 2013 in Casablanca. These events were a huge success. In fact, hundreds of visitors (engineers, scientists, farmers, technicians...) attend our booth for demos and presentations about the Buried Diffuser.
Mr Fouad DOUIRI, Moroccan Minister of Energy, Mines, Water and Environment and Mr. Mathieu Babaud Darret, Minister of Water and Forests of Côte d'Ivoire have long traded with Dr. Chahbani and its Moroccan partners.
The Buried Diffuser, as an innovative solution providing concrete answers to farmers problems, was definitely adopted. Several putting-in in many regions have been planned.

New concepts: Anticipated irrigation and Water injection and storage in the deep soil Layers of the plantations using the Buried Diffuser

                   New concepts: Anticipated irrigation and Water injection and storage in the deep soil Layers of the plantations using the Buried Diffuser

o Concepts
After the use of the buried diffuser for the regular irrigation, Chahtech SA has created a new method for “anticipated irrigation” and “water injection in the deep soil layers”. The goal of this new concept is to save and conserve the huge of water received during the wet season, for the next dry season.
More then that, in other regions of the world the challenge is higher: how to save and conserve the huge of water received during the wet or rainy years to be used during the long dry period: one till 3 years.
Both “anticipated irrigation” and “water injection” are solutions for drought mitigation and for climate change adaptation and for the regularisation of the crops yields.

o More details:
The “anticipated irrigation’’, instead of irrigation during the hot or the dry season, the
irrigation using buried diffusers is done during the autumn and winter or during the rainy season. The amount of water of the “anticipated irrigation” should cover the total need of the crop during the hot or dry season (spring and summer). This water amount is stored in the deep soil layers will be used by the deep or sub surface roots systems of the crops.
The Water injection in the deep soil layers is useful especially for trees crops. The injected
water comes from: dams, rivers, and springs. The amount of the injected water could cover the need of the trees for several years (2 to 3years) when the soil below 50cm is thick (1 meter or more). This injected water is conserved (stored) in the deep soil layers (50 cm below the soil surface) and used later by the deep root systems of the trees during a long drought period: six months till 3years. During the Drought the trees produce normally using the injected and stored water. According to long injection period (15 days to 90 days none stop: days and nights), it is recommended to use our “energy less” system of water “pumping” and distribution using the gravity. This system uses our second product: “the draining floater”. This system is described in another report which could be downloaded from our website: www.chahtech.com

o Trials in Fields
On February 2013 Chahtech SA started 2 trials in the field of a farmer in Nouvelle Matmata Arid region (South of Tunisia).
The first trial includes the installation of diffusers (each tree has 3 diffusers model 15/15) for 2 olive trees suffering from long drought (75% of the leaves are dried). Each tree was irrigated with 2250 litters using the diffusers. 2 Months later (April 2013) the 2 irrigated trees become green with new leaves and young branches. The irrigations water given to each tree is sufficient for 4 months.
The second trial is the injection of 10 cubic meters of water in the deep soil layers (below the buried diffuser) using only one buried diffuser model 15/30. The irrigation duration is 52 continuous days; no stop (24/24 hours, 7/7 days).
The excavation of a trench (6 meters long and 4 meters deep) to discover the wetted area of the deep soil layers below the buried diffuser which injected 10 000 litters showed the wetted area result of the injection of 10000 litters has 6 meters diameter and 2 meters deep. This means, that a trees equipped with 4 buried diffusers, will r receive, after 52 days of injection, 40 cubic meters. This volume (40 cubic meters stored in 100cm soil below the diffuser , containing minimum 10% clay), is sufficient to maintain the tree in life and in optimal production conditions, during 4 completely dry years.
