The book begins with an overview of the research topics which were addressed in the three different phases of the Dutch Priority Program on Acidification (DPPA), executed between 1985 and 1994. This chapter is followed by a chapter which deals with the emissions of acidifying substances, the concentrations and the deposition to forest and nature conservation areas. Prognoses are given for the acid deposition in 2000 and 2010; the deposition in the countries surrounding the Netherlands is also mentioned. The differences in the results of the DPPA-II are analysed.The third chapter deals with the effects of exposure and load on forests. The chapter moves from small-scale to large-scale: first the effects in laboratory-scale studies are described, then the effects in the field, both at stand level and on a regional scale. In addition, the critical thresholds (critical level of concentration and critical load of deposition) are discussed.The fourth chapter covers terrestrial ecosystems (or parts thereof) as well as weakly buffered surface waters, springs and other streams. Critical levels and loads are also discussed. The most important results are given in chapter 5.In the appendices of the book, so-called umbrella theme reports on deposition, stand modelling and effects on forests are presented which describe in more detail the scientific work performed in the third phase of the DPPA.This book will be of interest to anyone involved in research related to acidification and eutrophication; i.e., not only those who perform the research in the causal chain from emissions to effects, but also policy-makers and students.

Professional planning is commonly defined as an activity which is concerned with the rational allocation or exploitation of resources for man's maximum short- and long-term benefit. The science of. ecology is the study of the basic components of these resources (soil, water, air etc. ) and their inter relationships with living organisms. Planning and ecology therefore have many common interests and, as such, have long been associated in resource management. This association was, for example, reflected as early as the 19th century in the writings of Patrick Geddes, the progenitor of modern town planning, whose training as a biologist led him to re-interpret the phenomena of urbanization in ecological terms (Geddes, 1886). Since the time of Geddes the place of ecology has declined in planning circles as other professions and considerations, initially public health and engineering, latterly economic and sociological, have become more central. The reasons for this shifting emphasis are three-fold. First, they reflect changing social attitudes and aspirations in the post-war period. Secondly, many other professions and persuasions (agriculturalists, foresters, in dustrialists etc. ) became organized as pressure groups and helped shape public attitudes and governmental actions. Thirdly, and by far the most important reason, is the prevalence of misconceptions about ecology. Too many people, perhaps misled by the debate surrounding the' environmental movement', equate ecology with conservation. In reality, conservation is but one component part of ecology.

This book is an outcome of collaborative efforts of a multidisciplinary team of scientists. The core objective of this book is to provide cross-sectoral information on the different aspects of the terrestrial environment and ecosystems of Kuwait. The book will be considered as a ready source of information for those seeking information on the terrestrial environment and ecosystems, assessment and restoration, as well as sustainable uses and management. In spite of Kuwait’s hyper-arid environment, it is rich in natural resources including a wide range of native plants, animal species, different habitats, protected areas, diversified soils and water and oil resources. While the desert of Kuwait constitutes various features, such as sand sheet, sand dunes, nebkhas, inland and coastal sabkhas, rock outcrop, wadis and farming areas, it is rich in flora and fauna (native plants, mammals, birds, reptiles, etc.). Due to changing climate, deserts of Kuwait as well as other countries are under severe threat of degradation and the degradation may be irreversible. To realize these impacts, an effort is being made to provide a ready source of information to highlight the potential threats to the terrestrial ecosystems and formulate adaptation and mitigation strategies for long-term ecosystems services in Kuwait as well as other countries located in a desert environment, such as Gulf Cooperation Council Countries, Africa and countries in the Arab region. The book includes sixteen chapters covering multidiscipline subjects (such as natural resources, climate and climate change, geographical features, terrestrial habitats, ecosystems and threats, water and soil resources, agriculture, food security, water-energy-food-climate nexus, green-grey-blue water footprints of various crops, etc.). Thus, this book is a unique resource that provides the latest scientific information in a single volume.

This report describes each of the 14 case study sites in terms of its ecological interest, the extent of the impact of road construction on the sites, the mitigation measures taken, and the success of these mitigation measures.

Originally published in 1987, this book describes and discusses the vegetation of rivers and other watercourses in Europe with an emphasis upon distributional, community and historical ecology. It was firmly based upon many years of field investigations carried out by the author in various countries in the European Economic Community. The main purpose of the text was to increase the understanding of river vegetation in relation to the varying physical characteristics of the watercourses. The rivers of the EEC are considered in detail, with an emphasis upon the influences of landscape, geology, climate, settlement patterns, water use and management and pollution. This book will be of value to anyone with an interest in river botany.
