Irrigated agriculture in Jordan's highlands relies on overexploited groundwater. Drops in water tables and water quality, but also tougher policy measures by the government, threaten the sustainability of this activity which has long thrived on lax law enforcement and cheap desert land. This paper is based on field work in two locations of Azraq gr...
The desert of eastern Libya forms one of the most arid regions of the Sahara. The Great Man-Made River Project (GMRP) was established. It transports millions of cubic meters of water a day from desert wellfields to the coastal cities, where over 80% of the population lives. The Tazerbo Wellfield is one of the wellfields designed within the GMRP, de...

Regions with dry climates cover a large part of the world’s landmass (more than 40%). Collectively known by the English term "drylands", they encompass a wide range of ecosystems, including the American "deserts" of California, Nevada and Mexico ; the vast steppes of Central Asia and North Africa ; the Sahelian savannah and real deserts such as the...

The way in which animals move and use the landscape is influenced by the spatial distribution of resources, and is of importance when considering species conservation. We aimed at exploring how landscape-related factors affect a large herbivore's space-use patterns by using a combined approach, integrating movement (displacement and recursions) and...
We record two species of Diaphanosoma from Ounianga and Tibesti in Northern Chad, the first ctenopods to be found in the Sahara desert. One species, from a freshwater guelta on the south flanks of the Tibesti (D. excisum) is tropical; the second species, found in a freshwater lake in a largely saline environment (the Ounianga plateau) is new to sci...
