BioEarth: Envisioning and developing a new regional earth system model to inform natural and agricultural resource management

As managers of agricultural and natural resources are confronted with uncertainties in global change impacts, the complexities associated with the interconnected cycling of nitrogen, carbon, and water present daunting management challenges. Existing models provide detailed information on specific sub-systems (e.g., land, air, water, and economics). An increasing awareness of the unintended consequences of management decisions resulting from interconnectedness of these sub-systems, however, necessitates coupled regional earth system models (EaSMs). Decision makers’ needs and priorities can be integrated into the model design and development processes to enhance decision-making relevance and “usability” of EaSMs. BioEarth is a research initiative currently under development with a focus on the U.S. Pacific Northwest region that explores the coupling of multiple stand-alone EaSMs to generate usable information for resource decision-making. Direct engagement between model developers and non-academic stakeholders involved in resource and environmental management decisions throughout the model development process is a critical component of this effort. BioEarth utilizes a bottom-up approach for its land surface model that preserves fine spatial-scale sensitivities and lateral hydrologic connectivity, which makes it unique among many regional EaSMs. This paper describes the BioEarth initiative and highlights opportunities and challenges associated with coupling multiple stand-alone models to generate usable information for agricultural and natural resource decision-making

Fast and Practical Approximate String Matching

We present new algorithms for approximate string matching based in simple, but efficient, ideas. First, we present an algorithm for string matching with mismatches based in arithmetical operations that runs in linear worst case time for most practical cases. This is a new approach to string searching. Second, we present an algorithm for string matching with errors based on partitioning the pattern that requires linear expected time for typical inputs. 1 Introduction Approximate string matching is one of the main problems in combinatorial pattern matching. Recently, several new approaches emphasizing the expected search time and practicality have appeared [3, 4, 27, 32, 31, 17], in contrast to older results, most of them are only of theoretical interest. Here, we continue this trend, by presenting two new simple and efficient algorithms for approximate string matching. First, we present an algorithm for string matching with k mismatches. This problem consists of finding all instances o..

Fire science needs in the Pacific Northwest

12 pagesAfter a century of wildfire suppression, the costs and complexity of wildfire management are increasing. Population growth in fire-prone landscapes, climate change, and diverse land management objectives all contribute to a complex management environment. The number and types of managers and practitioners involved in wildfire management has also grown. Government agencies, land managers, air quality regulators, nonprofit organizations, community leaders, and others have a diversity of fire science and social science needs. To protect and restore fire-adapted communities and natural resources in the Pacific Northwest, a process for effective dissemination and accelerated user adoption of pertinent information, knowledge, tools, and expertise is necessary. An improved system to connect, engage, and exchange information between researchers and diverse groups affected by wild or prescribed fire could enhance exchange of existing fire science and technologies throughout the region, and encourage fire and land management stakeholders to evaluate and adopt relevant fire science.This project was made possible with funds from the Joint Fire Science Program, Oregon State University, University of Oregon, USDA Forest Service, and the USDA Bureau of Land Management
