Scientists state that planting big numbers of jatropha trees in desert areas could be an effective method of suppressing emissions of CO2.
+
Dubbed "carbon farming", researchers say the idea is financially competitive with modern carbon capture and storage tasks.
+
But critics say the idea might be have unforeseen, negative impacts including driving up food prices.
+
The research study has actually been released, external in the journal Earth System Dynamics.
+
Seeds of change
+
Jatropha curcas is a plant that came from Central America and is effectively adapted to severe conditions including exceptionally arid deserts.
+
It is already grown as a biofuel, external in some parts of the world due to the fact that its seeds can produce oil.
+
In this research study, German researchers showed that a person hectare of jatropha could catch approximately 25 tonnes of co2 from the environment every year. The scientists based their quotes on trees currently growing in trial plots in Egypt and in the Negev desert.
+
"The outcomes are overwhelming," stated Prof Klaus Becker, from the University of Hohenheim in Stuttgart.
+
"There was great growth, a great response from these plants. I feel there will be no issue attempting it on a much bigger scale, for instance 10 thousand hectares in the beginning," he stated.
+
According to the scientists a plantation that would cover 3 percent of the Arabian desert would absorb all the CO2 produced by cars and trucks and trucks in Germany over a twenty years period.
+
The scientists state that an important component of the plan would be the accessibility of desalination facilities. This implies that at first, any plantations would be confined to coastal areas.
+
They are hoping to develop larger trials in desert areas of Oman or Qatar. Prof Becker says that unlike other plans that just balance out the carbon that individuals produce, the planting of jatropha might be a good, brief term solution to climate change.
+
"I believe it is a great idea due to the fact that we are really drawing out co2 from the atmosphere - and it is totally different between extracting and preventing."
+
According to the scientist's calculations the expenses of suppressing carbon dioxide via the planting of trees would be in between 42 and 63 euros per tonne. This makes it competitive with other strategies, such as the more high capture and storage, external (CCS).
+
A variety of countries are presently trialling this innovation, external however it has yet to be deployed commercially.
+
Growing jatropha not only absorbs CO2 however has other benefits. The plants would help to make desert locations more habitable, and the plant's seeds can be collected for biofuel state the researchers, providing an economic return.
+
"Jatropha is perfect to be become biokerosene - it is even better than biodiesel," said Prof Becker.
+
But other specialists in this location are not encouraged. They point to the reality that in 2007 and 2008 big numbers of jatropha trees were planted for biofuel, specifically in Africa. But much of these endeavors ended in tears,, external as the plants were not extremely effective in dealing with dry conditions.
+
Lucy Hurn is the biofuels project supervisor for the charity, Actionaid. She says that while jatropha was once seen as the terrific, green hope the reality was really different.
+
"When jatropha was presented it was viewed as a wonder crop, it would grow on scrubland or marginal land," she said.
+
"But there are often people who require minimal land to graze their animals, they are getting food from that location - we wouldn't class the land as marginal."
+
She explained that jatropha is highly toxic and can pollute the land it is grown on, even in a desert. And she likewise had issues about the fairness of the concept.
+
"It is still someone else's land. Why enter and grow these huge plantations to handle an issue these people didn't actually cause?"
