NEXT GENERATION BUILDING MATERIALS The 21st century faces a radical change in how we produce construction materials – a shift towards cultivating, breeding, raising, farming, or growing future resources. This book presents innovative industrialized production methods for cultivated building materials, like cement grown by bacteria, bricks made of mushroom mycelium, or bamboo fibers as reinforcement for concrete. Spanning from scientific research to product development and architectural application, this book builds a bridge between the academic and the professional world of architecture. The book describes the challenges, strategies, and goals in the first part, followed by a second part on bamboo, A cultivated building material and a number of examples in the third part which form the bridge from cultivated materials to building products.

”Reduce, Reuse, Recycle, and Recover“ is the sustainable guideline that has replaced the ”Take, Make, Waste“ attitude of the industrial age. Based on their background at the ETH Zurich and the Future Cities Laboratory in Singapore, the authors provide both a conceptual and practical look into materials and products which use waste as a renewable resource. This book introduces an inventory of current projects and building elements, ranging from marketed products, among them façade panels made of straw and self-healing concrete, to advanced research and development like newspaper, wood or jeans denim used as isolating fibres. Going beyond the mere recycling aspect of reused materials, it looks into innovative concepts of how materials usually regarded as waste can be processed into new construction elements. The products are organized along the manufacturing processes: densified, reconfigured, transformed, designed and cultivated materials. A product directory presents all materials and projects in this book according to their functional uses in construction: load-bearing, self-supporting, insulating, waterproofing and finishing products.

This book provides a comprehensive overview of the wild relatives of crops and cultivated species found in India, covering their distribution, phylogenetic relationships with cultivated species, traits that are of economic and breeding value, and the perceived threats. It highlights the opportunities the wild relatives of cultivated species offer in terms of new genes and allelic variability, as well as several other exploitable economic and environmental benefits that can be harnessed with their conservation and cultivation. This helps facilitate their use – both directly and as part of the breeding program for related cultivated species, filling the gaps of genetic variability in the primary gene pool. It also discusses how they can be used in breeding programs using conventional technologies and the biotechnological approaches of recombinant DNA. Transfer of natural genes using recombinant DNA, known as “Cisgenesis,” can accelerate the process of incorporating these natural genes without genetic drag of undesirable features and biosafety concerns, and beyond taxonomic boundaries, in response to the demand for new cultivars to meet the challenges of climate change and ever-growing human population.

Using plant material as raw materials for construction is a relatively recent and original topic of research. This book presents an overview of the current knowledge on the material properties and environmental impact of construction materials made from plant particles, which are renewable, recyclable and easily available. It focuses on particles and as well on fibers issued from hemp plant, as well as discussing hemp concretes. The book begins by setting the environmental, economic and social context of agro-concretes, before discussing the nature of plant-based aggregates and binders. The formulation, implementation and mechanical behavior of such building materials are the subject of the following chapters. The focus is then put upon the hygrothermal behavior and acoustical properties of hempcrete, followed by the use of plant-based concretes in structures. The book concludes with the study of life-cycle analysis (LCA) of the environmental characteristics of a banked hempcrete wall on a wooden skeleton. Contents 1. Environmental, Economic and Social Context of Agro-Concretes, Vincent Nozahic and Sofiane Amziane. 2. Characterization of Plant-Based Aggregates. Vincent Picandet. 3.

A rich analysis of the complex dynamic between food collection and food production in the farming societies of precolonial south central Africa Engaging new linguistic evidence and reinterpreting published archaeological evidence, this sweeping study explores the place of bushcraft and agriculture in the precolonial history of south central Africa across nearly three millennia. Contrary to popular conceptions that place farming at the heart of political and social change, political innovation in precolonial African farming societies was actually contingent on developments in hunting, fishing, and foraging, as de Luna reveals.

Cultivated Plants, Primarily as Food Sources is a component of Encyclopedia of Food and Agricultural Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. Global food demand is forecast to double and possible triple, by the year 2050, when more than 10 billion people will need to be fed worldwide. To ensure adequate nutrition for this growing population food production must be expanded faster than the population. Following a longer introduction chapter with some information on the history of crop production, the land used for agriculture, the cropping systems and the future trends, comes the knowledge in depth: The grain and cereal, the edible been plants, the vegetables and plants for edible starch, oil, sugar and beverage production, the fruits and nuts, the fiber, forage and industrial crops. Each subject contains glossary and bibliography for better and deeper understanding. At each important plant the history, the production technology, the importance of the crop in nutrition of growing population, the feeding value, some short case stories, and the future trends are discussed. When considering plant foods in relation to human health, it should be remembered that plant foods may also have health value in addition to their nutritional value. It would seem possible to modify the composition of plant foods as to improve human health. In developing countries, poverty leads to food shortage and under nutrition and many populations survive largely on plant-based diets. In industrialized countries, relative affluence leads to over consumption of food and especially to over-consumption of animal foods at the expense of plant foods. These two volumes, cultivated plants, primarily as food sources, help to get more detailed knowledge to overcome the mentioned problem of the World. These volumes are aimed at the following five major target audiences: University and College Students Educators, Professional Practitioners, Research Personnel and Policy Analysts, Managers, and Decision Makers, NGOs and GOs.
