The wild beauty of deserts has always been a source of fascination the world over. Mankind and Deserts 2 – the second of three volumes – focuses on water, its absence or indeed its extreme scarcity, as well as on the ways in which salts come to be formed in areas such as these. Aridity of the climate does not exclude rainfall, after which deserts flourish; wet mists, dew, exceptional events separated by years of total drought. Water flows into temporary and disorganized networks but, occasionally, large rivers cross the deserts, giving rise to vibrant civilizations: the Nile, Tigris and Euphrates, Niger, to name a few. Temporary or permanent lakes collect water in basins without outlet to the ocean, referred to as endorrheic basins, such as Lake Chad. This results in salt accumulation and evaporitic formations. A large variety of salts crystallize, in addition to halite, among which is potash. Halite – common salt – is an essential resource and its trade leads to the creation of salt caravans, used to exchange it with gold, even on a 1-1 weight basis, generating subsequent wealth. From ancient, almost mythical, exploration to modern scientific studies, deserts have come to be better known yet still hold great appeal. This book traces the history of their knowledge while providing a basis for understanding their features and the tools needed for their protection, in an ever-changing world.

The wild beauty of deserts has always been a source of fascination the world over. Mankind and Deserts 1 – the first of three volumes – describes their location and geographic variety. There are both hot and cold deserts, those at high altitude or those at sea level, differing in climate but sharing the scarcity of water, extreme temperatures and often violent winds. According to paleoclimate evidence, however, deserts have not always been as arid as they are today. Deserts were a source of inspiration for many spiritual leaders, among them, Moses, Jesus and Muhammad; as well as conquerors, from Alexander the Great to Genghis Khan. Some avoided these deserts, or crossed them as fast as they could. Others adapted to them and developed vibrant civilizations and cities. From ancient, almost mythical, exploration to modern scientific studies, deserts have come to be better known yet still hold great appeal. This book traces the history of their knowledge while providing a basis for understanding their features and the tools needed for their protection, in an ever-changing world.

Microalgae and cyanobacteria are the first organisms in the oceanic food chain and are essential producers of oxygen and effective carbon dioxide traps. They are traditional sources of food proteins for Aztec, African and Asian populations, and some of them have even acquired the status of superfoods. Microalgae reviews the biological, ecological and biochemical characteristics of microalgae and cyanobacteria. They are true cellular factories, producing substances of interest such as original pigments, proteins and polysaccharides with biological activities. Their use covers many sectors of human activity including aquaculture, livestock breeding, agri-food, and human and veterinary medicine. This book presents their mode of production and the transformation processes that are applied to them, as well as the traditional and future valorization of algae. As they are a source of lipids and fatty acids, microalgae have become the focus of attention for the development of green fuels, such as biofuel.

Developed over several decades, the concept of aquatic biotechnology refers to aquatic organisms, be they of animal or plant origin. It involves transforming biological resources into products for human and animal consumption. The emergence of transgenic fish (such as AquAdvantage salmon) and their use as foodstuffs has reopened the societal debate on the place of genetically modified organisms in our diet. This new aquaculture based on genetic engineering is known as the "blue revolution." However, "blue" biotechnology is not limited to the production of genetically modified organisms; it also involves the use of biotechnological processes, such as enzymatic hydrolysis and fermentation, on aquatic resources. Aquatic Biotechnologies presents an overview of these biotechnological processes (genetic, enzymatic and fermentative engineering) as applied to aquatic organisms and their production methods (traditional aquaculture and aquaculture producing genetically modified organisms).

One of the challenges of our modern society is to successfully reconcile growing energy demand, demographic and food pressure and ecological and environmental urgency. This book offers an update on a rapidly evolving subject, that of modern photovoltaic systems capable of combining the needs of energy and ecological transition. Although photovoltaic solar energy is a well-proven technical solution in terms of energy, its development can compete with agricultural land or natural sites. New solutions are emerging: the installation of photovoltaic parks on industrial wasteland; agrivoltaics, which reconcile agricultural activity and energy production on the same surface; and ecovoltaics, which make it possible to make use of the unused surfaces under solar panels by developing ecological solutions capable of providing services to nature. These innovations are part of the response to the need to preserve terrestrial and aquatic ecosystems, halt the decline in animal and plant biodiversity and participate in the development of a new mode of sustainable development and green economy.

The wild beauty of deserts has always been a source of fascination the world over. Mankind and Deserts 3 – the third and final volume – focuses on wind, frequently present in all deserts, either hot or cold. Wind plays a major role in aridity and landscapes bear numerous forms due to its action, erosion, transportation and surface formations, some discreet and others spectacular, such as vast expanses of towering yardangs. Aeolian dynamics lead to dune formation, simple or associated with sand ridges or ergs, as in the Sahara. Mankind has attempted, to varying degrees of success, to cope with sand accumulation; ignoring aeolian dynamics has led many development projects to failure. This is developed by Yann Callot, a Professor at Lyon University who studied aeolian dynamics in the Sahara. Traditional societies have adapted to live in deserts, establishing vibrant civilizations with original ways of living, managing water resources and creating routes for trade, especially for salt. In a changing environment, useful lessons can be drawn from the genius of mankindÂs adaptation to such diverse and fragile environments. This is explained by Marc Côte, who was a Professor at Constantine (Algeria) and Aix-en-Provence Universities. From ancient, almost mythical, exploration to modern scientific studies, deserts have come to be better known yet still hold great appeal. This book traces the history of their knowledge while providing a basis for understanding their features and the tools needed for their protection, in an ever-changing world.
