Have you ever wondered why we eat wheat, rice, potatoes and cassava? Why we routinely domesticate foodstuffs with the power to kill us, or why we chose almonds over acorns? Answering all these questions and more in a readable and friendly style, this book takes you on a journey through our history with crop plants. Arranged into recurrent themes in plant domestication, this book documents the history and biology of over 50 crops, including cereals, spices, legumes, fruits and cash crops such as chocolate, tobacco and rubber.

The tropics are the source of many of our familiar fruits, vegetables, oils, and spice, as well as such commodities as rubber and wood. Moreover, other tropical fruits and vegetables are being introduced into our markets to offer variety to our diet. Now, as tropical forests are increasingly threatened, we face a double-fold crisis: not only the loss of the plants but also rich pools of potentially useful genes. Wild populations of crop plants harbor genes that can improve the productivity and disease resistance of cultivated crops, many of which are vital to developing economies and to global commerce. Eight chapters of this book are devoted to a variety of tropical crops—beverages, fruit, starch, oil, resins, fuelwood, fodder, spices, timber, and nuts—the history of their domestication, their uses today, and the known extent of their gene pools, both domesticated and wild. Drawing on broad research, the authors also consider conservation strategies such as parks and reserves, corporate holdings, gene banks and tissue culture collections, and debt-for-nature swaps. They stress the need for a sensitive balance between conservation and the economic well-being of local populations. If economic growth is part of the conservation effort, local populations and governments will be more strongly motivated to save their natural resources. Distinctly practical and soundly informative, this book provides insight into the overwhelming abundance of tropical forests, an unsettling sense of what we may lose if they are destroyed, and a deep appreciation for the delicate relationships between tropical forest plants and people around the world.

Production of food to meet the demands of an ever-increasing human population in the world is the major task and challenge to agriculture today. The conventional methods of plant breeding alone can no longer cope with the situation. The success of any crop improvement program depends on the extent of genetic variability in the base population, but due to denuding of forests and agricultural land, the naturally occurring pool of germplasm is being depleted. An urgent need is therefore ap parent to create new variability and increase the genetic base of agricul tural crops. Agricultural biotechnology has progressed to a stage in the produc tion of plants where specific characteristics to improve their yield, ap pearance, disease-resistance, nutritional quality and adaptation to ad verse soil conditions can be built into the seed. This concept of built-in quality implies a continuous scientific endeavour to improve plant char acters using a wide range of possibilities, and it also implies a scrutiny of the materials and methods available in the world today.

Given the central role of the food and agriculture system in driving so many of the connected ecological, social and economic threats and challenges we currently face, Rethinking Food and Agriculture reviews, reassesses and reimagines the current food and agriculture system and the narrow paradigm in which it operates. Rethinking Food and Agriculture explores and uncovers some of the key historical, ethical, economic, social, cultural, political, and structural drivers and root causes of unsustainability, degradation of the agricultural environment, destruction of nature, short-comings in science and knowledge systems, inequality, hunger and food insecurity, and disharmony. It reviews efforts towards 'sustainable development', and reassesses whether these efforts have been implemented with adequate responsibility, acceptable societal and environmental costs and optimal engagement to secure sustainability, equity and justice. The book highlights the many ways that farmers and their communities, civil society groups, social movements, development experts, scientists and others have been raising awareness of these issues, implementing solutions and forging 'new ways forward', for example towards paradigms of agriculture, natural resource management and human nutrition which are more sustainable and just. Rethinking Food and Agriculture proposes ways to move beyond the current limited view of agro-ecological sustainability towards overall sustainability of the food and agriculture system based on the principle of 'inclusive responsibility'. Inclusive responsibility encourages ecosystem sustainability based on agro-ecological and planetary limits to sustainable resource use for production and livelihoods. Inclusive responsibility also places importance on quality of life, pluralism, equity and justice for all and emphasises the health, well-being, sovereignty, dignity and rights of producers, consumers and other stakeholders, as well as of nonhuman animals and the natural world. - Explores some of the key drivers and root causes of unsustainability , degradation of the agricultural environment and destruction of nature - Highlights the many ways that different stakeholders have been forging 'new ways forward' towards alternative paradigms of agriculture, human nutrition and political economy, which are more sustainable and just - Proposes ways to move beyong the current unsustainable exploitation of natural resources towards agroecological sustainability and overall sustainability of the food and agriculture system based on 'inclusive responsibility'

Harnessing evolution for more sustainable agriculture As human populations grow and resources are depleted, agriculture will need to use land, water, and other resources more efficiently and without sacrificing long-term sustainability. Darwinian Agriculture presents an entirely new approach to these challenges, one that draws on the principles of evolution and natural selection. R. Ford Denison shows how both biotechnology and traditional plant breeding can use Darwinian insights to identify promising routes for crop genetic improvement and avoid costly dead ends. Denison explains why plant traits that have been genetically optimized by individual selection—such as photosynthesis and drought tolerance—are bad candidates for genetic improvement. Traits like plant height and leaf angle, which determine the collective performance of plant communities, offer more room for improvement. Agriculturalists can also benefit from more sophisticated comparisons among natural communities and from the study of wild species in the landscapes where they evolved. Darwinian Agriculture reveals why it is sometimes better to slow or even reverse evolutionary trends when they are inconsistent with our present goals, and how we can glean new ideas from natural selection's marvelous innovations in wild species.

The future of our food depends on tiny seeds in orchards and fields the world over. In 1943, one of the first to recognize this fact, the great botanist Nikolay Vavilov, lay dying of starvation in a Soviet prison. But in the years before Stalin jailed him as a scapegoat for the country’s famines, Vavilov had traveled over five continents, collecting hundreds of thousands of seeds in an effort to outline the ancient centers of agricultural diversity and guard against widespread hunger. Now, another remarkable scientist—and vivid storyteller—has retraced his footsteps. In Where Our Food Comes From, Gary Paul Nabhan weaves together Vavilov’s extraordinary story with his own expeditions to Earth’s richest agricultural landscapes and the cultures that tend them. Retracing Vavilov’s path from Mexico and the Colombian Amazon to the glaciers of the Pamirs in Tajikistan, he draws a vibrant portrait of changes that have occurred since Vavilov’s time and why they matter. In his travels, Nabhan shows how climate change, free trade policies, genetic engineering, and loss of traditional knowledge are threatening our food supply. Through discussions with local farmers, visits to local outdoor markets, and comparison of his own observations in eleven countries to those recorded in Vavilov’s journals and photos, Nabhan reveals just how much diversity has already been lost. But he also shows what resilient farmers and scientists in many regions are doing to save the remaining living riches of our world. It is a cruel irony that Vavilov, a man who spent his life working to foster nutrition, ultimately died from lack of it. In telling his story, Where Our Food Comes From brings to life the intricate relationships among culture, politics, the land, and the future of the world’s food.
