The chapters in this book were developed from some of the lectures presented at a sym posium at the XX International Congress of Entomology held in Florence, Italy in August 1996. The purpose of the symposium was to discuss the impact of evolving modern agricultural landscapes on the insect species, of both economic and ecological importance, that utilize that habitat. Agricultural policy, to some extent, influences the choices that farmers make and thereby the shape of the agricultural landscape. In order to move toward more sustainable agro ecosystems future policy makers will have to consider the history of land use, consumer demands for both environmentally sound and affordable products, and the conservation of biological diversity. I would hope the information contained in this book will help stimulate discussion about the consequences of policy decisions on our agricultural landscapes and their insect inhabitants. I thank all the speakers from the symposium and in particular those that have been able to contribute chapters to this book. There have been many delays, most due to circumstances beyond anyone's control. I would like to express my appreciation to Gloria Verhey and Patrick Dumont for taking care of the book in these final months.

This book creates a scientific base for the development and testing of sustainable production and land use systems in ecologically fragile and economically disadvantaged mountainous regions in Southeast Asia; to develop concepts for rural institutions that can reduce rural poverty and food insecurity, and improve livelihoods in mountainous regions in Southeast Asia; and to explore methods for analyzing complex ecosystems and their interactions with the socio-cultural, economic and institutional environment.

Insect-Plant Interactions, the latest edition in the Advances in Botanical Research series, which publishes in-depth and up-to-date reviews on a wide range of topics in the plant sciences, features several reviews by recognized experts on all aspects of plant genetics, biochemistry, cell biology, molecular biology, physiology, and ecology. - Publishes in-depth and up-to-date reviews on a wide range of topics in plant sciences - Presents the latest information on artificial photosynthesis - Features a wide range of reviews by recognized experts on all aspects of plant genetics, biochemistry, cell biology, molecular biology, physiology, and ecology

Successful management of agricultural landscapes depends on the recognition of the relationships between the processes and the structures that maintain the system. The rapidly growing science of Landscape Ecology quantifies the ways these ecosystems interact and establishes a link between the activities in one region and repercussions in another. A

This book delivers a realistic and feasible framework for creating resilient landscapes in an era of anthropogenic climate change. From across six continents, this book presents fifteen case studies of differing sociocultural, economic, and biophysical backgrounds that showcase opportunities and limitations for creating resilient landscapes throughout the world. The potential to create socio-ecological resilience is examined across a wide range of landscapes, including agricultural, island, forest, coastal, and urban landscapes, across sixteen countries: Argentina, Australia, Brazil, Denmark, Finland, Greece, Guatemala, Japan, Mexico, Norway, Samoa, South Africa, the United States, Turkey, Uruguay, and Vanuatu. Chapters discuss current and future issues around creating a sustainable food system, conserving biodiversity, and climate change adaptation and resilience, with green infrastructure, nature-based architecture, green-tech, and ecosystem services as just a few of the approaches discussed. The book emphasizes solution-oriented approaches for an "ecological hope" that can support landscape resiliency in this chaotic era, and the chapters consider the importance of envisioning an unpredictable future with numerous uncertainties. In this context, the key focus is on how we all can tackle the intertwined impacts of climate change, biodiversity loss, and large-scale land-cover conversion in urban and non-urban landscapes, with particular attention to the concept of landscape resiliency. The volume provides that much-needed link between theory and practice to deliver forward-thinking, practical solutions. This book will be of great interest to students, researchers, practitioners and policymakers who are interested in the complex relationship between landscapes, climate change, biodiversity loss, and land-based conversion at local, national and global scales.

This book aims (1) to lay out the historical underpinnings of the areawide pest (including weeds, plant and stored grain insect pests) management (AWPM) and to highlight current activity in the field; (2) to delve into concepts that have direct impact on the successful implementation of AWPM, which include: (i) biological and ecological concepts important for understanding the dynamics of populations in spatially heterogeneous environments; (ii) the critical role of inter-agency and multidisciplinary interactions in the development and implementation of AWPM programmes, which are often complex inter-agency and intergovernmental endeavours; (iii) the roles of modelling, meteorology and databases in AWPM programmes which, by their nature, are information intensive; and (iv) the importance of economic and sociological evaluation in successful AWPM implementation; and (3) to compile recent case examples of pest management programmes that have used the AWPM approach. A survey in presented on a wide variety of programmes developed for protecting agricultural and natural resource systems and which use a wide range of pest management tactics.
