Environmental Challenges And Medicinal Plants

This book sheds new light on the role of various environmental factors in regulating the metabolic adaptation of medicinal and aromatic plants. Many of the chapters present cutting-edge findings on the contamination of medicinal plants through horizontal transfer, as well as nanomaterials and the biosynthesis of pharmacologically active compounds. In addition, the book highlights the impacts of environmental factors (e.g., high and low temperature, climate change, global warming, UV irradiation, intense sunlight and shade, ozone, carbon dioxide, drought, salinity, nutrient deficiency, agrochemicals, waste, heavy metals, nanomaterials, weeds, pests and pathogen infections) on medicinal and aromatic plants, emphasizing secondary metabolisms. In recent years, interest has grown in the use of bioactive compounds from natural sources. Medicinal and aromatic plants constitute an important part of the natural environment and agro-ecosystems, and contain a wealth of chemical compounds known as secondary metabolites and including alkaloids, glycosides, essential oils and other miscellaneous active substances. These metabolites help plants cope with environmental and/or external stimuli in a rapid, reversible and ecologically meaningful manner. Additionally, environmental factors play a crucial role in regulating the metabolic yield of these biologically active molecules. Understanding how medicinal plants respond to environmental perturbations and climate change could open new frontiers in plant production and in agriculture, where successive innovation is urgently needed due to the looming challenges in connection with global food security and climate change. Readers will discover a range of revealing perspectives and the latest research on this vital topic.

Medicinal plants supply the ever-growing needs of humankind for natural chemicals, such as pharmaceuticals, nutraceuticals, agrochemicals, and chemical additives. These plants contain bioactive secondary metabolites, which possess antimalarial, anthelminthic, anti-inflammatory, analgesic, antimicrobial, antiarthritic, antioxidant, antidiabetic, antihypertensive, anticancer, antifungal, antispasmodic, cardioprotective, antithyroid, and antihistaminic properties. Secondary metabolites play a major role in the adaptation of plants to the changing environment and stress condition as they are affected by both biotic and abiotic stress. Humans rely on medicinal plants for various needs since ancient time, and their population still seems enough for fulfilling our demands. However, in the foreseeable future, we will be forced to think about the accessibility of resources for future generations. For these reasons, we must look for alternative sustainable options of resources which can protect these immensely important medicinal plants from various stresses induced by challenging environment. Evolving eco-friendly methodologies and mechanisms to improve these plants’ responses to unfavorable environmental circumstances is important in creating significant tools for better understanding of plant adaptations to various abiotic stresses and sustaining the supply of pharmaceuticals as global climate change intensifies. One of the great challenges in the near future will be the sustainable production of medicinal plants under increasing adverse effects of climate change. A combination of adverse demographic factors and climatological perturbations is expected to impact food and pharmaceutical production globally. Despite the induction of several tolerance mechanisms, medicinal plants often fail to survive under environmental extremes. To ensure their sustainable production under adverse conditions, multidisciplinary approaches are needed, and useful leads are likely to emerge. However, improving plants' performance under restrictive growth conditions requires a deep understanding of the molecular processes that underlie their extraordinary physiological plasticity. This edited volume emphasizes the recent updates about the current research on medicinal plants covering different aspects related to challenges and opportunities in the concerned field. This book is an attempt to bring together global researchers who have been engaged in the area of stress signaling, crosstalk, and mechanisms of medicinal plants. The book will provide a direction towards implementation of programs and practices that will enable sustainable production of medicinal plants resilient to challenging environmental conditions. Moreover, this book will instigate and commence readers to state-of-the-art developments and trends in this field.

The current global environmental crisis is primarily the result of non-standardized parameters for environmental regulation, and is impacting e.g. clean air, safe drinking water and the quality of food, particularly in developing nations. Due to their poor/lax execution of EIA protocols, newly developing countries are preferred destinations for establishing pollution-emitting industries, which results in the degradation and depletion of their natural resources. Lack of environmental policy intervention is another major incentive to base “dirty” industries in these nations. In order to ensure sustainable development, the highest-priority issues include the monitoring and eradication of environmental problems stemming from economic development; virtually every form of economic development primarily results in the loss of forests and thus biodiversity, followed by declining air quality and the contamination of natural resources. Sustainable development ensures responsible interactions with the environment, so as to minimize the depletion or degradation of natural resources and preserve environmental quality. It involves integrated approaches to understanding the importance of environmental management systems and policy measures that lead to improved environmental performance. This book addresses the environmental concerns associated with economic development, and with approaches to attaining sustainable economic development, which include monitoring the quality of water resources, soil erosion and degradation of the natural environment.

This book discusses molecular approaches in plant as response to environmental factors, such as variations in temperature, water availability, salinity, and metal stress. The book also covers the impact of increasing global population, urbanization, and industrialization on these molecular behaviors. It covers the natural tolerance mechanism which plants adopt to cope with adverse environments, as well as the novel molecular strategies for engineering the plants in human interest. This book will be of interest to researchers working on the impact of the changing environment on plant ecology, issues of crop yield, and nutrient quantity and quality in agricultural crops. The book will be of interest to researchers as well as policy makers in the environmental and agricultural domains.

Climate change is one of the greatest challenges of the 21st century. Climate is changing across our planet, largely, as a result of human activities. The indicators of climate change include physical responses such as changes in the surface temperature, atmospheric water vapour, severe climatic events, melting of glaciers, and a rise in sea level. Mountain ecosystems being exceptionally fragile are prone to both natural and anthropogenic drivers of change, which ranges from volcanic and seismic events and flooding to global climate change and of vegetation and soils, resulting from inappropriate agricultural and forestry practices and extractive industries. Environmental issues directly affect agricultural productivity, famine and pandemics, health, economy, and ecology. In this light, environmental protection, the practice of protecting the environment on individual, community, organizational, or governmental level, assumes a significant role. This book provides a holistic coverage of the basics of climate change, changes in biodiversity, phytosociological changes, and thus proposes a comprehensive set of solutions to resolve various issues related to environment and climate change. This book would be beneficial for researchers, policy makers, academicians, environmentalists, and university students.

This volume showcases current ethnobiological accounts of the ways that people use plants to promote human health and well-being. The goal in this volume is to highlight some contemporary examples of how plants are central to various aspects of healthy environments and healthy minds and bodies. Authors employ diverse analytic frameworks, including: interpretive and constructivist, cognitive, political-ecological, systems theory, phenomenological, and critical studies of the relationship between humans, plants and the environment. The case studies represent a wide geographical range and explore the diversity in the health appeals of plants and herbs. The volume begins by considering how plants may intrinsically be ‘healthful’ and the notion that ecosystem health may be a literal concept used in contemporary efforts to increase awareness of environmental degradation. The book continues with the exploration of the ways in which medically-pluralistic societies demonstrate the entanglements between the environment, the state and its citizens. Profit driven models for the extraction and production of medicinal plant products are explored in terms of health equity and sovereignty. Some of the chapters in this volume work to explore medicinal plant knowledge and the globalization of medicinal plant knowledge. The translocal and global networks of medicinal plant knowledge are pivotal to productions of medicinal and herbal plant remedies that are used by people in all variety of societies and cultural groups. Humans produce health through various means and interact with our environments, especially plants, in order to promote health. The ethnographic accounts of people, plants, and health in this volume will be of interest to the fields of anthropology, biology and ethnobiology, as well as allied disciplines.

Global society in the 21st century is facing challenges of improving the quality of air, water, soil and the environment and maintaining the ecological balance. Environmental pollution, thus, has become a major global concern. The modern growth of industrialization, urbanization, modern agricultural development and energy generation has resulted in the indiscriminate exploitation of natural resources for fulfilling human desires and needs, which has contributed in disturbing the ecological balance on which the quality of our environment depends. Human beings, in the truest sense, are the product of their environment. The man-environment relationship indicates that pollution and deterioration of the environment have a social origin. The modern technological advancements in chemical processes/operations have generated new products, resulting in new pollutants in such abundant levels that they are above the self-cleaning capacity of the environment. One of the major issues in recent times is the threat tohuman lives due to the progressive deterioration of the environment from various sources. The impact of the pollutants on the environment will be significant when the accumulated pollutants load will exceed the carrying capacity of the receiving environment. Sustainable development envisages the use of natural resources, such as forests, land, water and fisheries, in a sustainable manner without causing changes in our natural world. The Rio de Janeiro-Earth Summit, held in Brazil in 1992, focused on sustainable development to encourage respect and concern for the use of natural resources in a sustainable manner for the protection of the environment. This book will be beneficial as a source of educational material to post-graduate research scholars, teachers and industrial personnel for maintaining the balance in the use of natural sources for sustainable development.
