Competition and environmental stress are crucial factors for structuring plant population in natural habitats. Cyperus arenarius, a sedge of coastal sand dunes habitat, is a suitable species for coastal restoration and dune stabilization, but how salinity and plant density interact in affecting its growth is still unknown. Here, growth, survival, and physiological responses of C. arenarius to salinity (sea-salt) and plant density were investigated.

The investigation was conducted on three mungbean [Vigna radiata (L.) Wilczek] genotypes namely MH-421, MH-318 and Basanti genotypes to study their biochemical, and yield response in relation to terminal heat stress tolerance. The plants were raised in earthen pots (30 cm diameter) filled with 5.5 kg of dune sand (Typic Torrispamments) under screen house conditions. High temperature stress was given by manipulation of sowing dates i.e. normal sown (12th March, 2013) and late sown (29th March, 2013).

India is the biggest consumer of raw silk and silk fabrics and second largest producer of raw silk after China. There are two types of silk viz., mulberry silk and vanya silk (non-mulberry silk). India has vast potential for production of vanya silks which plays a major role in rural livelihood security. Vanya silk can also be produced from the cocoons of wild silkworm, Gonometa rufobrunnea insect. The main food plant of Gonometa rufobrunnea is Colophospermum mopane commonly called as mopane. Mopane is a xeric species of South Africa and introduced in India for sand dune stabilization.

A pot experiment was conducted under natural conditions of screen house to evaluate the effect of saline irrigation given at flowering stage on plant water status functioning and their tolerance in two chickpea (Cicer arietinum) genotypes viz. HC-3 and CSG-8962. The pots containing dune sand were saturated with Cldominated saline irrigation at (40-45 DAS) to maintain ECiw of 2.0, 4.0 and 6.0dS m-1 as compared to control. The control plants were irrigated with distilled water.

A detailed soil survey was undertaken in central state farm Jetsar, Sri Ganganagar, Rajasthan, India representing the arid climate with the aim of to assess the status and potential of land resources for the suitability and production potential of soils for chickpea. The area of the farm has been divided into three major landforms viz., sand dunes, reclaimed sand dunes and aeofluvial flood plain. Based on the variation in physiography and landforms, eight soil pedons were identified in the farm.

Although Egypt has already reached the water poverty limit, it possesses a high potential of brackish groundwater available from different aquifers. All Arab countries lie in the best sun-belt region in the world and Egypt has the highest number of sun hours all year round. Solar energy for groundwater desalination is an independent infinite energy resource; it has low running costs and reduces the contribution of greenhouse gases (GHG) to global warming.

The woman was still alive as unnatural thunder cracked across the sky. The lightning forked through the thrashing rain, stabbing at the desert sand. Rain splashed across the dunes, running down the bank towards the entrance of the tomb, washing over stone that had been parched for a thousand years. She was hardly more than a girl, her eyes betraying her fear as she shivered in the warm rain. The priests stood either side of her, holding her arms out from her body. Their heads were lowered - perhaps in shame, perhaps in an effort to keep them dry....
