Mycorrhizal fungi are microbial engines which improve plant vigor and soil quality. They play a crucial role in plant nutrient uptake, water relations, ecosystem establishment, plant diversity, and the productivity of plants. Scientific research involves multidisciplinary approaches to understand the adaptation of mycorrhizae to the rhizosphere, mechanism of root colonization, effect on plant physiology and growth, biofertilization, plant resistance and biocontrol of plant pathogens. This book discusses and goes into detail on a number of topics: the molecular basis of nutrient exchange between arbuscular mycorrhizal (AM) fungi and host plants; the role of AM fungi in disease protection, alleviation of soil stresses and increasing grain production; interactions of AM fungi and beneficial saprophytic mycoflora in terms of plant growth promotion; the role of AM fungi in the restoration of native ecosystems; indirect contributions of AM fungi and soil aggregation to plant growth and mycorrhizosphere effect of multitrophic interaction; the mechanisms by which mycorrhizas change a disturbed ecosystem into productive land; the importance of reinstallation of mycorrhizal systems in the rhizosphere is emphasized and their impact on landscape regeneration, and in bioremediation of contaminated soils; Ectomycorrhizae (ECM) and their importance in forest ecosystems and associations of ECM in tropical rain forests function to maintain tropical monodominance; in vitro mycorrhization of micro-propagated plants, and visualizing and quantifying endorhizal fungi; the use of mycorrhizae, mainly AM and ECM, for sustainable agriculture and forestry.

Heavy metals can be emitted into environment by both natural and anthropogenic sources, mainly mining and industrial activity. Human exposure occurs through all environmental media. Infants are more susceptible to the adverse effects of exposure. Increasing attention is now being paid to the mental development of children exposed to heavy metals. The purpose of this book is to evaluate the existing knowledge on intellectual impairment in children exposed to heavy metals in their living environment and to identify the research needs in order to obtain a clearer picture of the situation in countries and regions at risk, in which the economy is closely related to metallurgy and heavy metals emission, and to recommend a strategy for human protection. In greater detail the main objectives could be formulated as follows: to review the principal sources of single, and complex mixtures of, heavy metal pollutants in the environment; to identify suitable methodology for chemical analyses in the environment and in humans; to evaluate the existing methods for measuring mental impairment, including their reliability and validity; to recommend a standard testing protocol to be used in future research; to assess the future role of environmental heavy metal pollution in countries and regions at risk and its effects on children’s neurological development; to recommend a prevention strategy for protecting children’s health and development.
An unfortunate by-product of industrialization is the contamination of soil and water resources with toxic metals, which becomes an environmental concern when the concentration in soils begins to affect human health. Current remediation methods applicable to contaminated soils are expensive and environmentally invasive since they are based primarily on civil-engineering techniques. This book represents an overview of efforts in exploiting biological and chemical processes to reduce the inherent risk associated with metal-contaminated soils. It presents a comprehensive, up-to-date analysis of in situ immobilization and inactivation of toxic metals by means of plants, microorganisms and invertebrates.
Urban land is an environmental key topic considering the increasing urbani sation of our world. The amounting pressure on resources especially in the urban environment demand awareness across technical and political sectors and solid concepts for workable solutions. This book will address those people, who are key in coping with the challenges of sustainable urban land use management: Professionals in the growing field of urban land recycling and graduate students from different disciplines including urban planning, environmental sciences and geotechnics. Processes that lead to urban land degradation include the extraction of resources, their transformation into goods, the production of waste and conflicts in the allocation of land. Industrial soil pollution, soil sealing and urban sprawl pose serious challenges to resource management in urban environments. The possible implications are not necessarily restricted to the urban area but do have feedback into the countryside. The reduction of arable land in urban peripheries often causes enhanced pressure on back-country natural ecosystems such as forests, grass- and wetlands. Urban land recycling especially in the developing world is to be seen in the context of poverty alleviation and sustainable development. Ifwe don't get a proper sustainable use of urban land, as well as of water and other natural resources that relate to them, sustainable development will not be reached.

Current trends in population growth hint that global food production is unlikely to gratify future demands under predicted climate change scenarios unless the rates of crop improvement are accelerated. Crop production faces numerous challenges, due to changing environmental conditions and evolving needs for new plant-derived materials. These challenges come at a time when the plant sciences are witnessing remarkable progress in understanding fundamental processes of plant growth and development. Drought, heat, cold and salinity are among the major abiotic stresses that often cause a series of morphological, physiological, biochemical and molecular alterations which adversely affect plant growth, development and productivity, consequently posing a serious challenge for sustainable food production in large parts of the world, particularly in emerging countries. This emphasizes the urgency of finding better ways to translate new advances in plant science into concrete successes in agricultural production. To overcome the pessimistic influence of abiotic stresses and to maintain the food security in the face of these challenges, new, improved and tolerant crop varieties, contemporary breeding techniques, and cavernous understanding of the mechanisms that counteract detrimental climate changes are indubitably needed to sustain the requisite food supply. In this context, Improvement of Crops in the Era of Climatic Changes, Volume 1 provides a state-of-the-art guide to recent developments that aid in the understanding of plant responses to abiotic stresses and lead to new horizons vis-à-vis prime strategies for translating current research into applied solutions to create strong yields and overall crop improvement under such unfavourable environments. Written by a diverse group of internationally famed scholars, Improvement of Crops in the Era of Climatic Changes, Volume 1 is a brief yet all-inclusive resource that is immensely advantageous for researchers, students, environmentalists, soil scientists, professionals, and many others in the quest of advancement in this flourishing field of research.
