Plant Modification For More Efficient Water Use

Plant Modification for More Efficient Water Use is a compilation of the proceedings of the Symposium on Plant Modification for More Efficient Water Use. These proceedings aim to make significant progress in identifying the physiological and morphological characteristics of plants by providing considerable control of evapotranspiration and by exploring their possible manipulation. This book is divided into four parts focusing on genetic engineering, physiological and environmental factors, and modeling. The first part includes articles about breeding, genetic engineering, use of variety isogenes, genetic modification, and phenotype and drought tolerance in relation to efficient use of water. The second part presents articles about plant responses to water deficit, water-use efficiency, water stress, and drought resistance. It also provides articles on plant-water balance, carbon dioxide requirement, soil physical and chemical barriers, and soil temperature and air temperature. The third part describes models of plant growth for yield prediction; light models for estimating the shortwave radiation regime of plant canopies; and soil-plant-atmosphere model. In addition, this part includes a parametric analysis of the anatomy and physiology of the stomata. The last part offers a challenge on plant modification for more efficient water use.

For nearly a century, scientific advances have fueled progress in U.S. agriculture to enable American producers to deliver safe and abundant food domestically and provide a trade surplus in bulk and high-value agricultural commodities and foods. Today, the U.S. food and agricultural enterprise faces formidable challenges that will test its long-term sustainability, competitiveness, and resilience. On its current path, future productivity in the U.S. agricultural system is likely to come with trade-offs. The success of agriculture is tied to natural systems, and these systems are showing signs of stress, even more so with the change in climate. More than a third of the food produced is unconsumed, an unacceptable loss of food and nutrients at a time of heightened global food demand. Increased food animal production to meet greater demand will generate more greenhouse gas emissions and excess animal waste. The U.S. food supply is generally secure, but is not immune to the costly and deadly shocks of continuing outbreaks of food-borne illness or to the constant threat of pests and pathogens to crops, livestock, and poultry. U.S. farmers and producers are at the front lines and will need more tools to manage the pressures they face. Science Breakthroughs to Advance Food and Agricultural Research by 2030 identifies innovative, emerging scientific advances for making the U.S. food and agricultural system more efficient, resilient, and sustainable. This report explores the availability of relatively new scientific developments across all disciplines that could accelerate progress toward these goals. It identifies the most promising scientific breakthroughs that could have the greatest positive impact on food and agriculture, and that are possible to achieve in the next decade (by 2030).

This book sheds new light on the remote sensing of agriculture in South/Southeast Asian (S/SEA) countries. S/SEA countries are growing rapidly in terms of population, industrialization, and urbanization. One of the critical challenges in the region is food security. In S/SEA, although total food production and productivity have increased in previous decades, in recent years, the growth rate of food production has slowed down, mostly due to land use change, market forces and policy interventions. Further, the weather and climate systems in the region driven primarily by monsoon variability are resulting in droughts or flooding, impacting agricultural production. Therefore, monitoring crops, including agricultural land cover changes at regular intervals, is essential to predict and prepare for disruptions in the food supply in the S/SEA countries. The current book captures the latest research on the remote sensing of agricultural land cover/ land use changes, including mapping and monitoring crops, crop yields, biophysical parameter retrievals, multi-source data fusion for agricultural applications, and chapters on decision making and early warning systems for food security. The authors of this book are international experts in the field, and their contributions highlight the use of remote sensing and geospatial technologies for agricultural research and applications in South/Southeast Asia.

This dialogue between scientists and lawyers builds on the issues identified at the 1976 Conference on the Legal and Scientific Uncertainties of Weather Modification held at Duke University. It provides an in-depth consideration of the prospects for a usable weather modification technology in the near future and of the legal problems that will be r
