Drylands, a home for nearly 2.5 billion people, are highly vulnerable to anthropogenic climate change, and dryland area may expand to 50% of the Earth's surface by 2100. Climate change may aggravate the prevalence of undernutrition and malnutrition because of adverse effects on quantity and quality of food production in these regions. This book takes a holistic approach to sustainable management of drylands to make agriculture drought-resilient. Eminent scientists from around the world share their knowledge and experiences for adaptation and mitigation of the anthropogenic climate change through innovation in sustainable management of water, soil, crops, livestock, and fisheries. They antici...
Saline land is a resource capable of significant production. Recent advances in research in breeding for salt tolerance in wheat, biotechnology in rice, and selection and rehabilitation of salt-tolerant plants are of economic importance in arid/saline conditions. This book gives some practical approaches for saline agriculture and afforestation, and describes examples of cultivating salt-tolerant/halophytic plants for commercial interest on salt-affected land or with highly salinized water in Australia, China, Central Asia, Egypt, Pakistan, and Russia. It also explores the possibilities of arid/saline agriculture and afforestation in UAE.
Diazotrophic bacteria convert atmospheric nitrogen to plant-useable form and this input of nitrogen through biological fixation is of great agronomic importance. The contributions presented in this volume relate to free-living nitrogen fixers and the diazotrophs associated with plants. Symbiotic association of Frankia with non-legumes and cyanobacterial associations are also discussed. Research topics covered in this volume include the biochemistry and genetics of diazotrophs, recent developments in improvement of plant-microbe interactions and their molecular basis, the use of molecular probes in taxonomy and ecology of diazotrophs and reports on field applications, agronomic importance and improvement in methodologies for assessing their contribution to plants. This book provides valuable information not only for researchers working in the field of biological nitrogen fixation but also for biochemistry, molecular biologists, microbiologists and agronomists.
The 14th International Nitrogen Fixation Congress was held in Beijing, China from October 27th through November 1st, 2004. This volume constitutes the proceedings of the Congress and represents a compilation of the presentations by scientists from more than 30 countries around the World who came to Beijing to discuss the progress made since the last Congress and to exchange ideas and information. This year marked the 30th anniversary of the first Congress held in Pullman, Washington, USA, in 1974. Since then, this series of Congresses has met five times in North America (three in the United States and once each in Canada and Mexico), once in South America (Brazil), four times in Western Euro...
The effects of climate change on food production and security are many and varied and represent one of the biggest challenges facing humanity today. As the human population increases there is increasing pressure on land availability and water resources. In many staple crops, warming temperatures have caused decreases in overall yields but at the same time the demand for cheaper and more sustainable food has increased. This edited volume examines the effects of climate change on all aspects of food production and how this is affecting food security in many parts of the world. The book presents a series of chapters which describe new technologies aimed at mitigating these effects via, for example, genetic modification, microbial science, and the introduction of new crops.
This new volume aims to be the single source that discusses in a comprehensive and elaborate way the photosynthetic and respiratory mechanisms in plants under hostile situations and the proper mitigating strategies to continue uninterrupted photosynthesis and respiration under such situations. Photosynthesis and respiration are the two main physiological processes for sugar biosynthesis and mobilization for driving all other vital functions. This volume delivers a wealth of sound information on these processes for scientists, researchers, and academicians. With chapters from renowned scientists, researchers, and global leaders, this volume focuses on the effect of environmental stressors on ...
