Scientists say that planting great deals of jatropha trees in desert locations might be an effective method of suppressing emissions of CO2.
+
Dubbed "carbon farming", researchers state the concept is financially competitive with modern carbon capture and storage jobs.
+
But critics say the concept could be have unexpected, negative effects consisting of driving up food rates.
+
The research has actually been published, external in the journal Earth System Dynamics.
+
Seeds of modification
+
Jatropha curcas is a plant that came from Central America and is extremely well adjusted to harsh conditions consisting of incredibly arid deserts.
+
It is already grown as a biofuel, external in some parts of the world because its seeds can produce oil.
+
In this study, German scientists revealed that a person hectare of jatropha might capture up to 25 tonnes of carbon dioxide 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 results are frustrating," stated Prof Klaus Becker, from the University of Hohenheim in Stuttgart.
+
"There was excellent development, a great action from these plants. I feel there will be no problem trying it on a much larger scale, for example 10 thousand hectares in the beginning," he said.
+
According to the scientists a plantation that would cover three percent of the Arabian desert would take in all the CO2 produced by automobiles and trucks in Germany over a 20 year period.
+
The scientists state that an important element of the plan would be the schedule of desalination centers. This means that initially, any plantations would be restricted to coastal areas.
+
They are intending to establish larger trials in desert locations of Oman or Qatar. Prof Becker states that unlike other schemes that simply balance out the carbon that individuals produce, the planting of jatropha might be a good, short-term service to climate modification.
+
"I believe it is a great idea since we are really drawing out co2 from the atmosphere - and it is totally different in between drawing out and avoiding."
+
According to the scientist's calculations the expenses of suppressing carbon dioxide via the planting of trees would be between 42 and 63 euros per tonne. This makes it competitive with other strategies, such as the more high tech carbon capture and storage, external (CCS).
+
A variety of nations are presently trialling this innovation, external but it has yet to be deployed commercially.
+
Growing jatropha not only takes in 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, supplying a financial return.
+
"Jatropha is ideal to be become biokerosene - it is even better than biodiesel," stated Prof Becker.
+
But other experts in this location are not convinced. They indicate the reality that in 2007 and 2008 great deals of jatropha trees were planted for biofuel, specifically in Africa. But a lot of these ventures ended in tears,, external as the plants were not really effective in coping with dry conditions.
+
Lucy Hurn is the biofuels project supervisor for the charity, Actionaid. She says that while jatropha was once viewed as the terrific, green hope the truth was extremely different.
+
"When jatropha was presented it was seen as a miracle crop, it would grow on scrubland or limited land," she said.
+
"But there are typically individuals who need marginal land to graze their animals, they are getting food from that area - we wouldn't class the land as limited."
+
She mentioned that jatropha is extremely toxic and can contaminate the land it is grown on, even in a desert. And she likewise had issues about the fairness of the idea.
+
"It is still somebody else's land. Why enter and grow these huge plantations to handle an issue these people didn't actually trigger?"
