Book Description
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.

Book Description
Focusing on the different types of grassland farming and their impact on the environment, this book addresses issues facing environmental quality, namely soil, water and air quality and socioeconomic impacts. It also offers a commentary on how the different pastoral sectors influence environmental issues.

Book Description
This book is a social—ecological system description and feedback analysis of the Lake Tana Basin, the headwater catchment of the Upper Blue Nile River. This basin is an important local, national, and international resource, and concern about its sustainable development is growing at many levels. Lake Tana Basin outflows of water, sediments, nutrients, and contaminants affect water that flows downstream in the Blue Nile across international boundaries into the Nile River; the lake and surrounding land have recently been proposed as a UNESCO Biosphere Reserve; the basin has been designated as a key national economic growth corridor in the Ethiopian Growth and Transformation Plan. In spite of the Lake Tana Basin’s importance, there is no comprehensive, integrated, system-wide description of its characteristics and dynamics that can serve as a basis for its sustainable development. This book presents both the social and ecological characteristics of the region and an integrated, system-wide perspective of the feedback links that shape social and ecological change in the basin. Finally, it summarizes key research needs for sustainable development.

Book Description
This multidisciplinary book by the author of The Geology of Egypt is the result of many years of research. It attempts to reconstruct the history of the River Nile from its origins to its present shape and regimen and also to ascertain the amount of water which has been carried by the river during the course of its history. It examines the manner in which this water was utilized in the past and the ways in which it will have to be used in future if the inhabitants of the river basin are to cope with their anticipated needs. Part One traces the geological history of the Nile from the time it started to excavate its valley some six million years ago until the present shape was assumed during the wet period which affected Africa after the retreat of the ice of the last glacial age some 10,000 years ago. Part Two deals with the amount of water that the river and its tributaries carry at present and have carried in the past. Part Three discusses the utilization of the water of the Nile from the time of the first appearance of man in the valley until the present time. It traces man's attempt to harness the river from the earliest time to the building of the Aswan High Dam. The book evaluates the effects of the dam after twenty years of operation. Part Four covers the present water supply-demand balance in each basin state and discusses the future plans of these countries to use the waters of the Nile. The rapidly growing populations and the prolonged droughts of recent years have put pressure upon the available waters of the river.

Book Description
Environmental Impact Assessment (EIA) has become a vital management tool worldwide. EIA is a means of evaluating the likely consequences of a proposed major action which will significantly affect the environment, before that action is taken.This new edition of Wood's key text provides an authoritative, international review of environmental impact assessment, comparing systems used in the UK, USA, the Netherlands, Canada, the Commonwealth of Australia and New Zealand and South Africa.

Book Description
Borders offer opportunities as well as restrictions, and in the Horn of Africa they are used as economic, political, identity and status resources by borderland peoples. State borders are more than barriers. They structure social, economic and political spaces and as such provide opportunities as well as obstacles for the communities straddling both sides of the border. This book deals with the conduits and opportunities of state borders in the Horn of Africa, and investigates how the people living there exploit state borders through various strategies. Using a micro level perspective, the case studies, which includethe Horn and Eastern Africa, particularly the borders of Djibouti, Eritrea, Ethiopia, Sudan, Somalia, Kenya, Uganda and Tanzania, focus on opportunities, highlight the agency of the borderlanders, and acknowledge the permeabilitybut consequentiality of the borders.

Book Description
Time series econometrics is a rapidly evolving field. Particularly, the cointegration revolution has had a substantial impact on applied analysis. Hence, no textbook has managed to cover the full range of methods in current use and explain how to proceed in applied domains. This gap in the literature motivates the present volume. The methods are sketched out, reminding the reader of the ideas underlying them and giving sufficient background for empirical work. The treatment can also be used as a textbook for a course on applied time series econometrics. Topics include: unit root and cointegration analysis, structural vector autoregressions, conditional heteroskedasticity and nonlinear and nonparametric time series models. Crucial to empirical work is the software that is available for analysis. New methodology is typically only gradually incorporated into existing software packages. Therefore a flexible Java interface has been created, allowing readers to replicate the applications and conduct their own analyses.
