Progress towards a present-day diagnosis of, and future strategies for, environmental management of rivers and catchments, with particular reference to Mediterranean (semiarid) environments. Geomorphological processes at both the basin and the river levels, and their interactions and relations with human activities that interfere with them, are explored.

This book is an initial attempt to estimate the loads of heavy metal and nutrient loads into an industrial effluent receiving rivers of a typical industrializing catchment. It shows the effects and impacts of diffuse and point sources of these loads into the rivers, and illuminate management, capacity and policy gaps of riverine water and sediment monitoring in the sub-Saharan countries perspective from Ethiopia. The study was done in semi-arid catchments of Kombolcha city with industrialising urban and peri-urban areas in north-central Ethiopia. The Leyole and Worka rivers, which receives industrial effluent and wash-off from the catchments’ areas, were monitored for two years. This book contribute to our understanding on applicable methods to quantify loads of diffuse and point sources in data poor areas, and the most important contribution is to address the gaps in in controlling emission changes and. The results of this book contribute to the theory of river protection and understanding of water quality management of sub-Saharan African tropical rivers and sediments and provides policy options for improvement in rivers water quality of the sub-Saharan countries. In bridging this gap, this book proposed a model to estimate the total loads of nitrogen and phosphorus from a catchment.

Nitrogen (N) is potentially one of the most complex elements on the Earth. It is necessary for all biological activity, but creates negative impacts on water and air quality. There is a balancing act between deficiency and surplus and the forms of N available further complicate our understanding of the dynamics. Biological fixation provides some plants with N supply while others are totally dependent upon N being available in the soil profile for the roots to extract. Nevertheless, the demand for N will increase because the human population with its increasing growth requires more protein and thus more N. Understanding the global N cycle is imperative to meeting current and future nitrogen demands while decreasing environmental impacts. This book discusses availability, production, and recycling of N in air, water, plants, and soils. It features information on N impacts to soil and water quality, management of N in agroecosystems, and techniques to maximize the use efficiency while minimizing the risks of leakage of reactive N into the environment. This volume in the Advances in Soil Science series is specifically devoted to availability, production, and recycling of N with impact on climate change and water quality, and management of N in agroecosystems in the context of maximizing the use efficiency and minimizing the risks of leakage of reactive N (NO-3, N¬2O) into the environment.

This book focuses on the nature and properties of soils of Hindu Kush-Himalayas and their management for agricultural land use. It discusses all aspects of climatic variations and potential of resources in the Himalayan region including examples from Afghanistan, Bangladesh, Bhutan, China (Tibet), India, Myanmar, Nepal and Pakistan. Chapters cover the geology of the parent material of native soils, soils microbes, flora and fauna. Soil classification has been given in detail to better understand the nature of soils for judicious management strategies. The authors present land use practices and suggestions for changes in land use to benefit from the full potential of the soils in this region. Their ultimate aim is to find ways of feeding the ever-increasing population and raising the standard of life for the people living in the Himalayan mountain region.

Environmental problems in coastal ecosystems can sometimes be attributed to excess nutrients flowing from upstream watersheds into estuarine settings. This nutrient over-enrichment can result in toxic algal blooms, shellfish poisoning, coral reef destruction, and other harmful outcomes. All U.S. coasts show signs of nutrient over-enrichment, and scientists predict worsening problems in the years ahead. Clean Coastal Waters explains technical aspects of nutrient over-enrichment and proposes both immediate local action by coastal managers and a longer-term national strategy incorporating policy design, classification of affected sites, law and regulation, coordination, and communication. Highlighting the Gulf of Mexico's "Dead Zone," the Pfiesteria outbreak in a tributary of Chesapeake Bay, and other cases, the book explains how nutrients work in the environment, why nitrogen is important, how enrichment turns into over-enrichment, and why some environments are especially susceptible. Economic as well as ecological impacts are examined. In addressing abatement strategies, the committee discusses the importance of monitoring sites, developing useful models of over-enrichment, and setting water quality goals. The book also reviews voluntary programs, mandatory controls, tax incentives, and other policy options for reducing the flow of nutrients from agricultural operations and other sources.

Groundwater is an indispensable resource in many parts of the world, where it supports domestic water supply, irrigated agriculture and industry. Its increased, and often intensive, use during the last half century has created problems and raised concerns regarding the potential depletion of local aquifers, water quality degradation and various geo

The world consists of many complex systems, ranging from our own bodies to ecosystems to economic systems. Despite their diversity, complex systems have many structural and functional features in common that can be effectively si- lated using powerful, user-friendly software. As a result, virtually anyone can - plore the nature of complex systems and their dynamical behavior under a range of assumptions and conditions. This ability to model dynamic systems is already having a powerful influence on teaching and studying complexity. The books in this series will promote this revolution in “systems thinking” by integrating computational skills of numeracy and techniques of dynamic mod- ing into a variety of disciplines. The unifying theme across the series will be the power and simplicity of the model-building process, and all books are designed to engage the reader in developing their own models for exploration of the dyn- ics of systems that are of interest to them. Modeling Dynamic Systems does not endorse any particular modeling paradigm or software. Rather, the volumes in the series will emphasize simplicity of lea- ing, expressive power, and the speed of execution as priorities that will facilitate deeper system understanding.
