ABSTRACTThe Arava Valley is located in southeastern Israel and extends over a strip 15 km wide and 150 km long, from the Dead Sea in the north to the Red Sea in the south. Despite a hyper-arid climate, with annual rainfall ranging from 15 to 50 mm and maximum summer temperatures exceeding 40°C, most Arava residents depend on agricultural activities for their livelihood. The development of techniques for improving agricultural production includes the use of protected structures, called greenhouses, which have the advantage of optimizing water use and extending the growing season for most products. But little attention has been paid to the potential effect of relatively large-scale land-use change on the local climate of nearby settlements. Our research proposes to investigate the characterization and rate of land use change over the past few decades in several locations in the Arava Valley and to study the associated changes in energy budget in the surrounding areas. The first results so far show a clear expansion of greenhouse use in three different locations in the Arava and a change in energy budget associated with different land use. The interest of this type of research is to be able to identify the potential consequences of a change in land use associated with human activities on the local climate and on the living conditions for the communities living nearby.
