Sand dune fixation: A solar‐powered Sahara seawater pipeline macroproject

  title={Sand dune fixation: A solar‐powered Sahara seawater pipeline macroproject},
  author={Viorel Badescu and Richart B. Cathcart and Alexander A. Bolonkin},
  journal={Land Degradation \& Development},
The paper proposes macro‐engineering using tactical technologies that stabilize and vegetate barren near‐coast sand dune fields with seawater. Seawater that would otherwise, as commonly postulated, increase the Earth–ocean volume. Anthropogenic saturation of the ground with pumped seawater should fix widespread active sand dune fields in deserts (such as the westernmost Sahara). Seawater extraction from the ocean, and its deposition on dune sand, is made via solar‐powered pipeline… 

Dune Sand Fixation: Mauritania Seawater Pipeline Macroproject

Wide-spreading actively migratory sand dune fields are mainly found in the Earth’s climatically designated desert regions—“hot deserts” cover ~14.2% of Earth’s land (Peel et al. 2007; Parsons and

Exploiting Regional Topography and Macro-engineering to Transform Southeastern Jordanian Desert Into a Coastal Area

Jordan has a very short coastline, which is reflected in limited and expensive coastal tourism, as well as limited marine life. Therefore, a technical proposal to transform part of the Jordanian

Transatlantic Freshwater Aqueduct

This paper offers a technical and geopolitical reappraisal of a macro-engineering proposal to plumb Earth’s freshwater, siphoning some of it from a region of surplus (Amazon River Basin) to a region

Sustainable Design of an Artificial Lake in Jafer Basin Based on Gravity Flow

Jordan is a dry country which badly needs water bodies. This work proposes a design of a sustainable artificial lake in Jafer basin (JB). The design involves excavating a tunnel to connect Gulf of


Extensive dune sand deposits cover specific areas of Iraq. Dune sands are often an environment hazard during strong winds and sand storms particularly in the summer months. A little research has

Erosion of dune sands stabilised by grouting with lime–silica fume mix

Dune sands are often an environmental hazard during strong winds and sand storms, particularly in the summer months. Wherever a granular soil surface is left unprotected, it can be subjected to win...

Wind and sand control by an oasis protective system: a case from the southeastern edge of the Tengger Desert, China

Wind and sand control are important factors in combating desertification and protecting oases. An oasis protective system can provide these benefits, but quantitative research on protection effects

Sea Art: the Mediterranean Sea Terrace Proposal

A new art form, Sea Art, is announced. Complementing Land Art, the artist/macroengineer authoring team hereby proposes a deliberate and particular Mediterranean Sea terracing project. Sea Art could

Macro-engineering Design for an Artificial Lake in Southeastern Jordan

Water situation in Jordan has become very critical. A feasible solution is to desalinate water drawn from Gulf of Aqaba (GoA). Another problem that Jordan faces is the very short coastline. These two



Fluctuating deposition of ocean water drives plant function on coastal sand dunes

Sea‐level rise will alter the hydrology of terrestrial coastal ecosystems. As such, it becomes increasingly important to decipher the present role of ocean water in coastal ecosystems in order to

Reversing the flow: water and nutrients from the sea to the land

effect We understand clearly the fluxes of atmosnheric water One area of immediate planetary-scale concern is the increasing carbon level of the atmosphere. Another is the decreasing carbon level of

Remobilization of southern African desert dune systems by twenty-first century global warming

The results suggest that dunefields are likely to be reactivated (the sand will become significantly exposed and move) as a consequence of twenty-first century climate warming.

The role of the mineral component in surface stabilization processes of a disturbed desert sandy surface

The stabilization of sandy and loamy surfaces in semiarid and arid areas by topsoil crusts protecting the soil against wind or runoff erosion is well known. Destruction of such crusts, often by

Late Pleistocene and Holocene dune activity and wind regimes in the western Sahara Desert of Mauritania

The western Sahara Desert in Mauritania is dominated by extensive sand seas consisting largely of linear dunes. Analyses of Landsat images, geomorphic and stratigraphic studies, and optically

Water requirements for cultivatingSalicornia bigeloviiTorr. with seawater on sand in a coastal desert environment

The forage and oilseed halophyte,Salicornia bigeloviiTorr., was grown in gravity-drained lysimeters set in open plots of the same crop over two seasons in a coastal desert environment in Sonora,

Long‐term effects of restoration on soil hydraulic properties in revegetation‐stabilized desert ecosystems

Improving structure of soils found at 0–5 cm depth, and increasing the thickness of biological soil crusts are both associated with sand dune revegetation‐stabilization in arid northwestern China.

Water for the desert—a viewpoint

The dwindling water resources combined with climatological conditions which severely affected several areas of the world, particularly those where subsistence agriculture and nomadic animal husbandry
