I would like to thank the Woodstock Foundation for their generous support of this project and the University of Vermont’s Rubenstein School of the Environment and Natural Resources. ii Abstract Natural resource managers are faced with significant challenges as they seek to ensure that forests continue to provide critical goods, services, and functions. Increasingly, managers must continually accommodate shifting societal demands on forests, increased threats from damaging insects, diseases, and invasive species, and a changing climate. These forces of change, referred to by many as global environmental change, represent one of the greatest challenges facing forest resource managers today. The uncertainty and variability around the potential future impacts on forest systems, compels managers to continually adapt to change, implement alternative management approaches, and regularly evaluate the outcomes of our management decisions. This report applies an adaptive management framework, originally developed by the US Forest Service, to assist the Marsh-Billings-Rockefeller National Historical Park in planning for future forest management. In this report we provide a road map for resource managers at MABI to mitigate and adapt to the challenges posed by a changing climate and a host of other stressors, to help ensure that the forest remains productive and resilient into the future. In addition, this report utilizes forest landscape simulation modeling techniques to evaluate the potential long-term impacts of a range alternative management approaches and climate change scenarios on future forest conditions. iii Table of contents Acknowledgements ......................................................................................................................... ii

Explanations for these trends take economic, political, and human ecological forms. Growth Forest plantations in urban and global markets for forest products, coupled with rural to urban migration, may spur the Forest transition conversion of fields into tree farms. Government programs also stimulate tree planting. These programs Tree farms Rural to urban migration occur frequently in nations with high population densities. Quantitative, cross-national analyses suggest that these forces combine in regionally distinctive ways to promote the expansion of forest plantations. In Africa and Asia plantations have expanded most rapidly in nations with densely populated rural districts, rural to urban migration, and government policies that promote tree planting. In the Americas and Oceania plantations have expanded rapidly in countries with relatively stable rural populations, low densities, and extensive tracts of land in pasture.

    Approaches to Adaptive Water Management in the Amudarya River Basin Integrated Project New Approaches to Adaptive Water Management under Uncertainty in the 6th EU framework programme New approaches to adaptive water management under uncertainty - the NeWater project NeWater (New Approaches to Adaptive Water Management under Uncertainty) is a transdisci- plinary research project funded by the European Union within its 6th framework programme (contract No: 511179 GOCE). It joins 35 research partners from Europe, Central Asia and Africa and many associated organizations from the water resource management area. Within the framework of the project research and stakeholder activities were carried out in seven river ba- sins in Europe, Africa and Central Asia. Aim The aim of the project is to improve existing methods and develop new approaches for inte- grated water resources management taking the complexity of river basins and uncertainties of climate and socio-economic changes into account. The project focuses particularly on opportuni- ties and barriers for a transition to more adaptive water management needed to prepare river basins for the challenges of sustainable resource use under current and future conditions. Approach NeWater concentrated on those elements of a water management regime that are essential for integrated and adaptive water management. It developed a framework and methods to analyze those elements and to achieve a transition to more adaptive water management. Concepts and methods were applied to analyze the current water

Cumming 1 ABSTRACT. Forests both support biodiversity and provide a wide range of benefits to people at multiple scales. Global and national remote sensing analyses of drivers of forest change generally focus on broad-scale influences on area (composition), ignoring arrangement (configuration). To explore meso-scale relationships, we compared forest composition and configuration to six indicators of economic growth over 23 years (1992–2015) of satellite data for 23 island nations. Based on global analyses, we expected to find clear relationships between economic growth and forest cover. Eleven islands lost 1 to 50% of forest cover, eight gained 1 to 28%, and four remained steady. Surprisingly, we found no clear relationship between economic growth trends and forest-cover change trajectories. These results differ from those of global land-cover change analyses and suggest that conservation-oriented policy and management approaches developed at both national and local scales are ignoring key meso-scale processes. Key Words: deforestation; economic indicators; land-cover change; land-use change; landscape composition; landscape configuration; remote sensing INTRODUCTION Cumming et al.
