Scientists say that planting large numbers of jatropha trees in desert areas might be a reliable method of suppressing emissions of CO2.
+
Dubbed "carbon farming", scientists say the concept is economically competitive with modern carbon capture and storage jobs.
+
But critics say the concept might be have unexpected, negative effects including increasing food rates.
+
The research has actually been released, external in the journal Earth System Dynamics.
+
Seeds of change
+
Jatropha curcas is a plant that originated in Central America and is effectively adjusted to severe conditions consisting of exceptionally arid deserts.
+
It is already grown as a biofuel, external in some parts of the world because its seeds can produce oil.
+
In this research study, German scientists revealed that one hectare of jatropha might capture up to 25 tonnes of co2 from the environment every year. The researchers based their price quotes on trees presently growing in trial plots in Egypt and in the Negev desert.
+
"The outcomes are overwhelming," said Prof Klaus Becker, from the University of Hohenheim in Stuttgart.
+
"There was good growth, a great action from these plants. I feel there will be no issue attempting it on a much larger scale, for example ten thousand hectares in the start," he stated.
+
According to the scientists a plantation that would cover 3 percent of the Arabian desert would take in all the CO2 produced by vehicles and trucks in Germany over a twenty years period.
+
The scientists state that a vital element of the strategy would be the accessibility of desalination facilities. This implies that at first, any plantations would be confined to coastal locations.
+
They are intending to develop bigger trials in desert locations of Oman or Qatar. Prof Becker states that unlike other schemes that just offset the carbon that individuals produce, the planting of jatropha might be a great, short-term option to climate modification.
+
"I think it is a great concept because we are actually extracting carbon dioxide from the atmosphere - and it is totally different between extracting and preventing."
+
According to the scientist's calculations the expenses of curbing co2 via the planting of trees would be in between 42 and 63 euros per tonne. This makes it competitive with other methods, such as the more high tech carbon capture and storage, external (CCS).
+
A number of nations are presently trialling this innovation, external however it has yet to be released commercially.
+
Growing jatropha not only soaks up CO2 but has other advantages. The plants would assist to make desert locations more habitable, and the plant's seeds can be collected for biofuel say the scientists, offering a financial return.
+
"Jatropha is ideal to be turned into biokerosene - it is even better than biodiesel," said Prof Becker.
+
But other experts in this location are not encouraged. They point to the truth that in 2007 and 2008 great deals of jatropha trees were planted for biofuel, specifically in Africa. But a number of these ventures ended in tears,, external as the plants were not extremely effective in coping with .
+
Lucy Hurn is the biofuels project supervisor for the charity, Actionaid. She says that while jatropha was once viewed as the excellent, green hope the reality was really different.
+
"When jatropha was presented it was viewed as a wonder crop, it would grow on scrubland or limited land," she stated.
+
"But there are typically individuals who require marginal land to graze their animals, they are getting food from that area - we wouldn't class the land as limited."
+
She pointed out that jatropha is extremely harmful and can pollute the land it is grown on, even in a desert. And she also had issues about the fairness of the idea.
+
"It is still somebody else's land. Why go in and grow these enormous plantations to deal with an issue these people didn't in fact trigger?"
