Food security is an issue of global concern, and it will be determined to a large extent by developments in plant nutrition. This publication examines key topics relating to plant nutrition with special reference to integrated nutrient management for crop production, including present and future demand for plant nutrients, soil fertility and crop production, management of plant nutrients and their sources, nutrient management guidelines for major field crops, economic and policy issues, food quality and consumer health, and environmental issues.
This text focuses on underutilized wild plants that can help to reduce food deficiency in developing nations. Edible wild plants are viewed as a potential solution for overcoming food insecurity for families in these regions, with a specific focus on sustainable production and conservation measures. Detailed analysis of specific wild plants is provided, including the nutritional contents of each plant. A full list of edible wild plants is included for the benefit of researchers, plus a pictorial guide for easy identification of these plants. Specific case studies are provided in which edible wild plants are used to reduce food insecurity, and the diversity of edible wild plants is studied from a global perspective. In developing countries, a significant obstacle to human survival is the increasing gap between food availability and the growing human population. Food insecurity results in less consumption of fruits and vegetables and leads to mineral and vitamin deficiency for individuals in these regions. Edible Wild plants: An alternative approach to food security focuses on growing and using wild plants in order to reduce food insecurity and malnutrition. Wild edible plants are inexpensive and are a rich source of antioxidants, vitamins, fiber, and minerals. As the first book to specifically focus on edible wild plants and their vital role in food security and nutrition, this text is incredibly valuable to any researcher studying innovative potential solutions to food deficiency in the developing world.
The burgeoning demand on the world food supply, coupled with concern over the use of chemical fertilizers, has led to an accelerated interest in the practice of precision agriculture. This practice involves the careful control and monitoring of plant nutrition to maximize the rate of growth and yield of crops, as well as their nutritional value.
Plant nutrients are the vital elements essential for plant growth and survival, with key roles in adapting to challenging environments. Each nutrient, whether required in relatively large (macronutrients) or minute concentrations (micronutrients) plays a unique role in plant life cycle. Both the insufficient and surplus concentrations of these nutrients may render negative impacts on plant growth and development and therefore their homeostasis is considered critical for optimal plant growth and yield. Plant Nutrition and Food Security in the Era of Climate Change comprehensively reviews all critical plant nutrients. Chapters include topics such as: biological roles, uptake and transport of vital nutrients in plants; an in-depth review of the roles of potassium, calcium, magnesium and trace element; molecular breeding approaches for enhanced plant nutrients; and exploring the rhizosphere microbiome for enhance nutrient availability. Written by leading experts in the field of plant biology, this is an essential read for researchers and scientists interested in plant science, agronomy, food security and environmental science. - A comprehensive review of all the important plant nutrients - Discusses plant homeostasis under natural and changing environments - Introduces novel approaches and state-of-the-art tool for enhancing the levels of targeted nutrients within plant tissues
This volume is a compilation of extended abstracts of all papers presented at the 14th International Plant Nutrition Colloquium. Over 500 oral and poster presentations illustrate current knowledge and research emphasis in this subject, providing a comprehensive view of the state of plant nutrition research.
New evidence this year corroborates the rise in world hunger observed in this report last year, sending a warning that more action is needed if we aspire to end world hunger and malnutrition in all its forms by 2030. Updated estimates show the number of people who suffer from hunger has been growing over the past three years, returning to prevailing levels from almost a decade ago. Although progress continues to be made in reducing child stunting, over 22 percent of children under five years of age are still affected. Other forms of malnutrition are also growing: adult obesity continues to increase in countries irrespective of their income levels, and many countries are coping with multiple forms of malnutrition at the same time – overweight and obesity, as well as anaemia in women, and child stunting and wasting.
Updates for many countries have made it possible to estimate hunger in the world with greater accuracy this year. In particular, newly accessible data enabled the revision of the entire series of undernourishment estimates for China back to 2000, resulting in a substantial downward shift of the series of the number of undernourished in the world. Nevertheless, the revision confirms the trend reported in past editions: the number of people affected by hunger globally has been slowly on the rise since 2014. The report also shows that the burden of malnutrition in all its forms continues to be a challenge. There has been some progress for child stunting, low birthweight and exclusive breastfeeding, but at a pace that is still too slow. Childhood overweight is not improving and adult obesity is on the rise in all regions. The report complements the usual assessment of food security and nutrition with projections of what the world may look like in 2030, if trends of the last decade continue. Projections show that the world is not on track to achieve Zero Hunger by 2030 and, despite some progress, most indicators are also not on track to meet global nutrition targets. The food security and nutritional status of the most vulnerable population groups is likely to deteriorate further due to the health and socio economic impacts of the COVID-19 pandemic. The report puts a spotlight on diet quality as a critical link between food security and nutrition. Meeting SDG 2 targets will only be possible if people have enough food to eat and if what they are eating is nutritious and affordable. The report also introduces new analysis of the cost and affordability of healthy diets around the world, by region and in different development contexts. It presents valuations of the health and climate-change costs associated with current food consumption patterns, as well as the potential cost savings if food consumption patterns were to shift towards healthy diets that include sustainability considerations. The report then concludes with a discussion of the policies and strategies to transform food systems to ensure affordable healthy diets, as part of the required efforts to end both hunger and all forms of malnutrition.
Emerging Technologies for Promoting Food Security: Overcoming the World Food Crisis discusses rising energy prices, increased biofuel use, water scarcity, and the rising world population, all factors that directly affect worldwide food security. The book examines the range of approaches to promoting global food security, including novel and existing agricultural and husbandry techniques for safe and sustainable food production. It is divided into three parts beginning with an overview of food security, an analysis of key drivers of food insecurity, and nutrition and food security. Part Two examines emerging technologies for plant and animal food security, with subsequent chapters discussing topics from genetic and aquaculture technologies, pest and disease control, environmental and policy issues affecting food security, and an in-depth analysis of water management and methods to reduce post-harvest losses. - Provides a comprehensive overview of food security - Thoroughly discusses rising energy prices, increased biofuel use, water scarcity, and the rising world population, all factors that directly affect worldwide food security - Covers the emerging technologies for plant and animal food security - Analyzes the policy issues affecting food security
