The Non-governmental organisation Autre Terre helps develop a technique to “green up the Sahel”

Saturday, 10 October 2015 20:11

“Farming in the Sahel, without water, is possible!”
says the Non-governmental organisation Autre Terre.

It was created in 1982, and is based in Liège. It wants to be part of a program to put a new type of farming in the Sahel in place. 

It’s an innovative technique that offers a new opportunity to stop the region becoming a desert, and green it up.

The technique is based on the use of Nguiguiss (scientific name: pilostigma reticulatum), a shrub that can draw out water buried deep in the ground, so it can be used by other plants.

“It all started when our new African partner, Agrecol, told us about a famer’s innovation which was discovered in the 90s”, explains Luc Lambert, who is in charge of the strategic marketing mission at Autre Terre.

“At the time, local famers noticed that mango trees planted near Nguiguiss did better and grew quicker than the others”.

Using this information, the Non-governmental organisation Autre Terre has provided technical and financial help to provide famers with the shrub from 2011 onwards.


In 2012, 3,012 cuttings of Nguiguiss were replanted on an area covering more than 15 hectares. 


In September 2014, Autre Terre and its partners continued to support the project and 2,700 mango plants were replanted near Nguiguiss so they could benefit from its water and nutrient supplies. 

“A year later, we have a success rate of above 70% (of plants that took)”, says Luc Lambert. 

“The next step is to test this technique with other types of plants. Dakar University is in charge of the next experiments”.

The Liège non-governmental organisation says the discovery offers unimagined perspectives for this region: the possibility to “green up” the Sahel and “block the violent wind”, and increase the number of shaded zones, which are good for farming.

While "Flavor" is very subjective, and each country that grows mangoes is very nationalistic, these are the mango varieties that are the most sought after around the world because of sweetnesss (Brix) and demand.

The Chaunsa has a Brix rating in the 22 degree level which is unheard of!
Carabao claims to be the sweetest mango in the world and was able to register this in the Guiness book of world records.
Perhaps it is time for a GLOBAL taste test ???

INDIA 2016 : Mango production in state likely to take a hit this year

TNN | May 22, 2016, 12.32 PM IST

Mangaluru: Vagaries of nature is expected to take a toll on the production of King of Fruits - Mango - in Karnataka this year. A combination of failure of pre-monsoon showers at the flowering and growth stage and spike in temperature in mango growing belt of the state is expected to limit the total production of mango to an estimated 12 lakh tonnes in the current season as against 14 lakh tonnes in the last calendar year.

However, the good news for fruit lovers is that this could see price of mangoes across varieties decrease marginally by 2-3%. This is mainly on account of 'import' of the fruit from other mango-growing states in India, said M Kamalakshi Rajanna, chairperson, Karnataka State Mango Development and Marketing Corporation Ltd.

Karnataka is the third largest mango-growing state in India after Uttar Pradesh and Maharashtra.

Mangoes date back 65 million years according to research ...

Experts at the Birbal Sahni Institute of Palaeobotany (BSIP) here have traced the origin of mango to the hills of Meghalaya, India from a 65 million year-old fossil of a mango leaf. 

The earlier fossil records of mango (Mangifera indica) from the Northeast and elsewhere were 25 to 30 million years old. The 'carbonized leaf fossil' from Damalgiri area of Meghalaya hills, believed to be a mango tree from the peninsular India, was found by Dr R. C. Mehrotra, senior scientist, BSIP and his colleagues. 

After careful analysis of the fossil of the mango leaf and leaves of modern plants, the BISP scientist found many of the fossil leaf characters to be similar to mangifera.

An extensive study of the anatomy and morphology of several modern-day species of the genus mangifera with the fossil samples had reinforced the concept that its centre of origin is Northeast India, from where it spread into neighbouring areas, says Dr. Mehrotra. 

The genus is believed to have disseminated into neighb…
