Des chercheurs de l'université de Tel-Aviv ont recherché des solutions pour accroître la capture de carbone dioxyde sans cependant utiliser les terres arables. Leur intéressante idée consiste à s'intéresser aux déserts et aux terres riches en sels qui sont habituellement considérées comme infertiles.
Les tamaris pourraient être une solution intéressante. En effet, certaines variétés de tamaris poussent naturellement dans les déserts. Ces arbres ont cependant besoin d'un minimum d'eau pour se développer. Ces plantes pourraient également servir dans la production de carburant. Une solution qui permettrait de réserver les terres arables à la production de denrées alimentaires.

ABSTRACT
Research Note: The utilization of plants for mitigating carbon dioxide accumulation in the atmosphere in Clean Development Mechanism (CDM) projects and biofuel production causes a severe burden on the limited sources of arable land and fresh water. This research is aimed at finding alternative plant types for biomass and biofuel production among desert halophytes. Such plants have the advantages of being naturally adapted to grow under the harsh desert conditions, on non-arable soils irrigated with reclaimed sewage or other types of brackish water. Exceptionally fast growing salt-resistant genotypes were identified among native populations of Tamarix of Israel. These may serve for future CDM projects and short-rotation forestry for biomass production. Another plant that originated from East Africa, Euphorbia tirucalli was also shown to be able to grow under desert conditions and saline water irrigation. This plant has been named in the literature as a potential source of biofuel.
