New interventions are needed to reduce the burden of vector-borne diseases like malaria and dengue, which are among the most serious and prevalent infectious diseases worldwide. The release of genetically modified (GM) mosquitoes may offer an alternative strategy to do so while circumventing the pitfalls of current vector control methods. Contemporary methodologies are stalling because of drug resistance, absence of vaccines and inadequate mosquito control techniques. GM mosquitoes have been developed that are resistant to pathogen infection and transmission, but the public-health and environmental consequences of releasing such insects are unclear, mainly because of a lack of knowledge of the ecology and population biology of mosquitoes. This book is the reflection of a workshop, held in June 2002, that addressed these issues. Experts on mosquito ecology met to discuss the current knowledge of mosquito ecology with respect to GM-insect technology. Emphasis of the workshop was on evaluating how human health and natural ecosystems, including target wild-mosquito populations, will respond to the invasion of GM vectors.This volume should stimulate discussion by clearly showing the importance of vector ecology for prevention of vector-borne diseases.

The food market is changing from a producer-controlled to a consumer-directed market. A main driving force is consumer concern about agricultural production methods and food safety. More than before, the consumer demands transparency of the production and processing chain. A food chain can be quite complex and the use of models has become indispensable to handle this complexity. Modelling tools are becoming increasingly important to guide the decisions for production of high-quality and safe agricultural foods. With the aid of models it becomes possible to control and predict quality attributes, so that product innovation can be done more efficiently. However, quality is an elusive concept, and there is always an aspect of subjectivity and uncertainty. A novel approach in the agro-food chain would be to tackle subjective elements and uncertainty in modelling by using Bayesian statistics and Bayesian Belief Networks. Bayesian approaches use prior probabilities (partly accounting for subjectivity) to estimate posterior probabilities, resulting in higher accuracy than is possible with classical statistical techniques.Thus, the variability and uncertainty in data and decisions, inherent in a complex food chain, can be dealt with.

The European Landscape is under stress of changing land use and a changing attitude of its users. Globalization, the disappearance of the iron curtain and the recent EU enlargement to 25 countries have changed the economic and environmental dimensions of Europe. Europe is changing its face from a western and eastern part to one European Union and to fast connections between its centres of activity. The rural and cultural heritage of Europe has to be adapted to cope with this change. However, its landscape is worth to be conserved as well, because it represents the European history in the same way as castles and churches. It even more represents the history of the common people, because it has been the tradition of the rural population that made these landscapes. It cannot be prevented that Europe is changing and it is good that Europe adapts to the new dimensions of the world. We, in Europe, have to define what we think is important and what must be conserved, what can be adapted to be used for new functions and what can be abolished because it has no value. These decisions will determine the new dimensions of the European landscapes. The Frontis Workshop on the New Dimensions of the European Landscape was held on 10-12 June 2002. Wageningen University and Research Centre organized this workshop aiming to develop visions on the landscape in Europe, its development and design in the future and to strengthen the international network in landscape planning.

Mankind has manipulated the quantity and quality of soil water for millennia. Food production was massively increased through fertilization, irrigation and drainage. But malpractice also caused degradation of immense areas of once fertile land, rendering it totally unproductive for many generations. In populated areas, the pollutant load ever more often exceeds the soil’s capacity for buffering and retention, and large volumes of potable groundwater have been polluted or are threatened to be polluted in the foreseeable future. In the past decades, the role of soil water in climate patterns has been recognized but not yet fully understood.The soil-science community responded to this diversity of issues by developing numerical models to simulate the behavior of water and solutes in soils. These models helped improve our understanding of unsaturated-zone processes and develop sustainable land-management practices. Aimed at professional soil scientists, soil-water modelers, irrigation engineers etc., this book discusses our progress in soil-water modeling. Top scientists present case studies, overviews and analyses of strengths, weaknesses, opportunities and threats related to soil-water modeling. The contributions cover a wide range of spatial scales, and discuss fundamental aspects of unsaturated-zone modeling as well as issues related to the application of models to real-world problems.

Concern about the environmental impacts of transgenic crops is one of the major reasons for the EU’s quasi-moratorium on GMOs. The contributions in this book show that the economic implications of these concerns are far-reaching and complex. They range from the farm level to research and technology development on the one side and consumer reactions on the other side, and influence not only government response but also international trade and public and private incentives for R&D. Each contribution includes a comment, which raises questions that need further investigation. A summary of the questions in research topics concludes the contributions. The book will be of interests for policy makers as well as scholars working in established areas of social and natural sciences with an interest in the complex issues related to the release of transgenic crops.

Avian Influenza has become one of the biggest threats for human and animal health. The old paradigm was that the disease in waterfowl, poultry, pigs and man was caused by separate viruses that each stayed reasonably well within their own niche. The only danger to man was considered being infected by pigs, being the mixing vessel, where avian and human influenza viruses could come together and exchange genetic material to form new viruses that are potentially dangerous to man.This has dramatically proven wrong during the last decade, with huge outbreaks in the USA, Europe, and Asia. The H5N1 strain that caused human deaths in Hong Kong appeared to be transmitted directly from poultry to man. This initiated sudden awareness that pigs were not a necessary intermediate in the transmission chain. During the AI outbreaks in Italy, mutation of low-pathogenicity viruses into high-pathogenicity viruses in poultry appeared another new threat, and further evidence that the poultry sector had a wolf in sheep’s clothing. It put pressure on development of diagnostic methods that could be used in large monitoring programmes.In The Netherlands a human fatality, after increased reports of conjunctivitis during a H7N7 outbreak, signalled that different AI strains could be fatal to man. Also, the huge economic losses and difficulties in controlling the spread of the infection in densely populated poultry areas, problems with vaccination and lack of marker vaccines demonstrated that the current control policy must be improved. These events led to an international AI conference with experts from Asia, USA and Europe.In this book you will find new views on the issues, expert opinions and the results of in-depth discussions among avian experts of around the world that do not want to give up against this dangerous virus.

The workshop “Environmental Change and Malaria Risk: Global and Local Implications” was held to conclude a 5-year collaborative research project on environmental change and malaria risk, with field research in Kenya and Brazil. It was fitting that such a large group of specialists was able to attend the workshop and contribute with a chapter in which the predicted environmental changes were viewed from different angles. We would like to thank the Netherlands Foundation for the Advancement of Tropical Research (WOTRO) and the National Programme for Research on Climate Change and Air Quality (NOP) for having funded our work so generously. Wageningen UR – Frontis is thanked for having arranged the workshop and for its financial contribution. We would especially like to thank Petra van Boetzelaer for having assisted with the logistics of the workshop, and Paulien van Vredendaal for having spent many hours in the type editing of the chapters, making publication of this book possible.

Due to globalization and internationalization of agri-food production, the arena of competition and competitive advantage is moving from individual firms operating on spot markets towards supply chains and networks. Therefore, coordination between firms within the chain becomes more important. Topics like costs, efficiency, risk and investment analysis have received little empirical attention within chain and network research. Nonetheless, these performance measures are of vital importance for continuity of individual companies, chains and networks.This book aims at offering a coherent view on this matter by discussing the possibilities and limitations of quantifying performance, risks and investments in the agri-food chain. A wide variety of approaches from different economic disciplines was used to analyse the complex systems of agri-food supply chains and develop appropriate models for management decision support. Research gaps and discussion points are identified by an international forum of researchers in order to enhance progress in this field.
