A collection of papers prepared for the European Forum on Integrated Environmental Assessment's (EFIEA) Policy Workshop on Scaling Issues in Integrated Assessment, held from 12-19 July 2000.

Integrated Assessment of Scale Impacts of Watershed Interventions is the outcome of a multi-disciplinary research team of social scientists, hydrologists (groundwater and surface water), modellers; and bio-physical scientists who have worked together over five years to develop an integrated model of the sustainability of biophysical, economic and social impacts of watersheds. Impacts of watershed interventions are assessed at upstream, mid-stream and downstream locations of two hydrological units that are characterised with differential bio-physical attributes. The editors propose that watershed interventions, when integrated with hydro-geology and bio-physical aspects, have greater influence on the resilience of the socio-ecological system. This book takes these aspects in to consideration and in the process provides insights in to watershed design and implementation. Integrates hydrogeology, bio-physical, and socioeconomic aspects of watersheds in a hydrological context Provides a comprehensive understanding of the impacts of watershed interventions Assesses the role of watershed interventions in enhancing household resilience Provides hydrological and socio-economic methodologies for design of sustainble watershed interventions including scale and institutional arrangements for implementing and sustaining watershed interventions

Ecologists, agronomists, and others who may question the validity of current models for determining sustainable growth of agroecosystems, need a new set of analytical tools that more effectively address the complex nature of related processes. Those who challenge traditional assumptions of optimization and static factors in agricultural modeling de

Bridging the gap between local knowledge and western science is essential to understanding the world's ecosystems and the ways in which humans interact with and shape those ecosystems. This book brings together a group of world-class scientists in an unprecedented effort to build a formal framework for linking local and indigenous knowledge with the global scientific enterprise. Contributors explore the challenges, costs, and benefits of bridging scales and knowledge systems in assessment processes and in resource management. Case studies look at a variety of efforts to bridge scales, providing important lessons concerning what has worked, what has not, and the costs and benefits associated with those efforts. Drawing on the groundbreaking work of the Millennium Eco-system Assessment, Bridging Scales and Knowledge Systems will be indispensable for future efforts to conduct ecosystem assessments around the world.

Faced with the twin threats of peak oil and climate change, many governments have turned for an answer to the apparent panacea of biofuels. Yet, increasingly, the progressive implementation of this solution demonstrates that the promise of biofuels as a replacement to fossil fuels is in fact a mirage that, if followed, risks leaving us short of power, short of food and doing as much damage to the climate as ever -- let alone the consequent impact on biodiversity due to additional loss of habitat for agricultural production and on rural development due to the additional stress on traditional farming systems. Worse still, these risks are being ignored. In this definitive expos Mario Giampietro and Kozo Mayumi present a theoretical framework and exhaustive evidence for the case against large scale biofuel production from agricultural crops. This book will be vital, sobering reading for anyone concerned with energy or agricultural policy, or bioenergy as a complex system.

This assessment report is a component of the multiple-scale southern African sub-global assessment (SAfMA), which investigated the condition and trends of ecosystem services and human well-being in the Gariep basin from 1993 to 2003, as well as future scenarios and possible responses to ecosystem change. The assessment features highlights from four local-scale assessments nested within the basin: Sehlabathebe, Great Fish River, Richtersveld and the Gauteng Province.

Ecologists, agronomists, and others who may question the validity of current models for determining sustainable growth of agroecosystems, need a new set of analytical tools that more effectively address the complex nature of related processes. Those who challenge traditional assumptions of optimization and static factors in agricultural modeling demand new methods beyond differential equations and traditional statistical tests. Multi-Scale Integrated Analysis of Agroecosystems explores alternative ways to study agricultural sustainability, presenting new approaches to organizing data and applying complex systems theory to actual cases. This innovative text recognizes the changing dynamics of the multiple processes and cross-relations within an environment, proposing a clearer analysis of agroecosystems than that which can be provided by rigid, reductionist methods. Main concepts, new vocabulary and narratives, and practical examples open the book, followed by technical chapters that provide a more detailed explanation of concepts. The final section of the book presents a tool kit based on these concepts, resulting in strong support of empirical observations that challenge traditional notions regarding the sustainability of farming systems, food systems, and agroecosystems.
