OUTLINE Background IGBP Phase Two Earth System Science Partnership Integrated Regional Studies (approach) Integrated Regional Studies (example) Role of Information-Computational Infrastructure SB RAS Integrated Interdisciplinary Environmental Projects Background for Northern Eurasia IRS
Background Basic tendenciesof regional environmental studies are analyzed on the basis of national and international Programs and Projects devoted to investigation of changes in environment caused by growing anthropogenic pressure and Global Climate Change.
Environment = Earth geographic envelope (Atmosphere, Hydrosphere and Active Layer of Lithosphere) • Environmental Sciences: • Multidisciplinary (Physics, Chemistry, Biology, Ecology, Social Sciences, etc.) • Monitoring (networks of local sensors, satellite remote sensing) • Mathematical modeling of processes and understanding/handling huge amounts of data • Computational-Information Technologies form infrastructure of basic and applied Environmental Sciences • Challenges: • To understand anthropogenic influence on regional/global scale; • To elaborate recipes for diminishing its negative consequences; • To suggest a way for sustainable development in the changing environment.

IGBP Phase Two Objective To describe and understand Earth System dynamics focusing on the interactive biological, chemical and physical processes the changes that are occurring in these dynamics and the role of human activities in these changes
CHARACTERISTICS OF IGBP II More integrative, more interdisciplinary Global change versus climate change Strong base in biogeochemical sciences More emphasis on issues of societal concern More emphasis on the regional scale Strategic partnerships via the Earth System Science Partnership (ESS-P)
Earth System Science Partnership Systemic behaviour of Earth's environment is due to a combination of external forcing - primarily variations in solar radiation levels near the Earth's surface - and a large and complex array of feedbacks and forcings within Earth's environment itself. Level of understanding of processes occurring in the Earth System, achieved mainly due to development of computational models and network of environment monitoring, requires to consider regional processes influence on the whole system functioning. Impossible to analyze dynamics of regional systems in details without proper consideration of global processes influence. And vice versa!
Earth System Science Partnership START Start Health Health
The Earth is currently operating in a no-analogue state. In terms of key environmental parameters, the Earth System has recently moved well outside the range of natural variability exhibited over at least the last half million years.The nature of changes now occurring simultaneously in the Earth System, their magnitudes and rates of change are unprecedented. From: Steffen et al. 2003
Earth System and Regional Processes • Current knowledge demonstrates that, at the regional level, aspects of global change manifest significantly different—yet surprisingly coherent and teleconnected and may affect Earth System dynamics. • Examples of small scale processes acting on large distances and long times: • Chemical species transport; • Permafrost border shifts. • Region might vary from a part of continent (Northern Eurasia) to a scale of natural/anthropogenic complex (Great Vasyugan Bog/ an irrigation system. • ESSP is currently developing a small set of Integrated Regional Studies (IRS), designed to contribute sound scientific understanding in support of sustainable development at the local level. These studies will also improve overall knowledge of regional-global linkages in the context of Earth System dynamics and seek to generate new knowledge about a region’s climatological, ecological, biogeochemical and hydrological functioning, the impact of land use change on these functions, and the interaction between it and the Earth system.
Integrated Regional Studies (approach) Formulated within the second phase of IGBP approach to Integrated Regional Studies shows it in most clear form. Apart necessity to take into account interrelations between regional and global processes here stressed is: necessity of usage of multidisciplinary approaches, based on information-computational technologies and applying basic science results to understanding of regional consequences of specific environment dynamics for population and socioeconomic situation in the region under study as well as strong demand in properly educated researchers is announced.
Integrated Regional Studies (IRS) • Based on the concept of the region as a holistic entity in the context of the Earth System; • Contribute sound scientific understanding in support of sustainable development in the region; • Contribute to a quantitative and qualitative understanding of regional-global linkages and the consequences of changes in these linkages. • Overall Approach • Each IRS be developed and led by scientists in the region concerned. The studies will reflect the individual characteristics, interests, scientific capabilities and development priorities of the regions themselves; there should be no prescribed or uniform templates for implementation. The commonality between the studies will be based on the fact that all within the set should address the same overall questions: • What will the region be like in 50 years (2050)? • What will be the consequences of these projected changes (scenarios) for thewelfare of the region? • What are the consequences for the Earth System?
‘Region' in an IRS refers to a large geographical area that must transcend national boundaries as appropriate, according to the following: • IRSs must: • transcend disciplinary boundaries across natural and social sciences, address all relevant aspects of marine, terrestrial, atmospheric, social, economic, cultural, historical etc. components of the Earth System; • reflect the particular socio-economic and biophysical characteristics of the region ; and • address regional research as an integrative Earth System science from planning to the synthesis and completion stages of such studies. • IRSs must study how the region functions as an entity as a whole and how that functioning might change.
An IRS must have some explicit relationship to a major feature of Earth System functioning (e.g., the Asian Monsoon system, the Amazon Basin, the Antarctic cryosphere). IRSs should be built around regions that may function as switch or choke points or hot spots, in which small changes in regional systems may lead to profound changes in the ways in which the Earth System operates. ‘Integrated' in IRSs refers specifically to two types of integration: (i)'horizontal integration', involving the integration of elements and processes within and across a region; and (ii) 'Vertical integration', involving the two-way linkages between the region and the global system.
An IRS must: • assess the influence of regional processes on Earth System functioning (and vice-versa) • be integrative (natural and social sciences, all components of the Earth System, planning to synthesis) • contribute sound scientific understanding in support of sustainable development in the region • be scientifically-driven by scientists in the region, but with global collaboration Integrated Regional Studies: example
Large Scale Biosphere-Atmosphere Experiment in Amazonia (LBA) • 80 research groups - 600 scientists • How does Amazonia function as a regional entity (e.g., natural cycles of water, energy, aerosols, carbon, nutrient and trace-gases)? • How will changes in land use and climate affect the biological, chemical and physical functioning of Amazonia, including its sustainability and influence on global climate?
Evolution of the Scientific Process • Pre-electronic • Theorize &/or experiment, alone or in small teams; publish paper • Post-electronic • Construct and mine very large databases of observational or simulation data • Develop computer simulations & analyses • Exchange information quasi-instantaneously within large, distributed, multidisciplinary teams
software computers sensor nets instruments colleagues data archives a new global infrastructure • information on demand - like power from a socket • the Grid is an emergent infrastructure to deliver dependable, pervasive and uniform access to globally distributed, dynamic and heterogeneous resources • problems of scalability, interoperability, fault tolerance, resource management and security
The GridThe Semantic Web “Resource sharing & coordinated problem solving in dynamic, multi-institutional virtual organizations”
