Insects are increasingly being recognized not only as a source of food to feed the ever growing world population but also as potential sources of new products and therapeutic agents, among which are sterols. In this study, we sought to profile sterols and their derivatives present in the desert locust, Schistocerca gregaria, focusing on those with potential importance as dietary and therapeutic components for humans.

The impact of Asian dust on the determination of cloud phase is analyzed over dust sources and downwind using cloud phase products from cloud-aerosol lidar and infrared pathfinder satellite observations (CALIPSO), atmospheric infrared sounder (AIRS), moderate resolution imaging spectroradiometer (MODIS), and polarization and anisotropy of reflectances for atmospheric sciences coupled with observations from a lidar (PARASOL). The results show that the presence of dust greatly affects determination of cloud phase in both source and downwind regions.

It is widely believed that the Sahara desert is no more than ~2–3 million years (Myr) old, with geological evidence showing a remarkable aridification of north Africa at the onset of the Quaternary ice ages. Before that time, north African aridity was mainly controlled by the African summer monsoon (ASM), which oscillated with Earth’s orbital precession cycles. Afterwards, the Northern Hemisphere glaciation added an ice volume forcing on the ASM, which additionally oscillated with glacial–interglacial cycles.

A new research, conducted over a period of ten years in Mojave Desert, has found that arid areas absorb an unexpectedly large amount of carbon as levels of carbon dioxide increase in the atmosphere

Land-use and land-cover change in the Thar Desert region of Rajasthan threatens the persistence of many ecologically and economically important species. The Bishnoi people of Rajasthan have religiously protected a keystone tree species, Prosopis cineraria, locally known as the Khejeri tree, for over five centuries. We conducted the first comparative study that tests the widely held assumption that Bishnoi presence is positively associated with P. cineraria abundance in nineteen villages in rural Rajasthan.

Desertification: The Invisible Frontline, which was published by the UNCCD, emphasizes that, as the climate changes, so is the face of the earth, and with devastating effects on the lives of those who depend on the land. This publication examines desertification as a cause of global conflict and instability.

Plantation drive undertaken by J&K Forest Department in the arid cold region of Ladakh have led to sprouting of innumerable groves that harbor even wild lives across Ladakh, but one of the most remarkable achievements is the successful growth of wild willow in hundreds of acres of land at an altitude of 14000 feet on Changthang tableland since 1962.

Dimming prospects for solar energy have caught up with a massive renewable-energy project planned for the Sahara Desert. By 2050, according to its backers, DESERTEC, a network of solar plants and other renewable sources scattered across North Africa and the Middle East, could generate more than 125 gigawatts of power that could be used locally or delivered to Europe through high-voltage direct-current cables beneath the Mediterranean Sea.

Humans may be destabilising desert ecosystems across the world, according to a new study.
