Session 16: Fractal Modeling
convenors: Qiuming Cheng
(qiuming@yorku.ca) York University, Canada; Frits Agterberg (agterber@NRCan.gc.ca) Geological Survey of Canada, Canada.

Fractals and chaos have become parts of mathematical geoscience during the past 30 years. They help to explain various random components in statistical models that otherwise are mostly deterministic such as those considered in various applications of the general linear model and in kriging. It has become clear that fractals and power-law relations usually are associated with relatively simple laws of self-similarity or scale independence. Multifractal modeling and the theory of self-organized criticality have opened new avenues for further research as well. Many non-linear modeling techniques in our field have been borrowed from physics and chemistry where non-static solutions of equations can result in singularities. These theoretical developments have already resulted in new practical approaches such as singularity mapping in geochemical exploration for new mineral deposits.

convenors: Jan Harff
(jan.harff@io-warnemuende.de) University Szczecin, Poland; Jiaxue Wu (jesse-wu@tongji.edu.cn) Sun Yat-sen University, Guangzhou, China.

Today, as in ancient times, and even increasingly in the future the societal development depends on the interaction of oceans and continents and changing environments of the coastal zone. This holds for the supply of energy, natural marine resources, threats of disasters, and coastal erosion. Marine geology and oceanography provide the scientific base for an understanding of the natural processes and their driving forces. Mathematical models of these processes allow today numerical simulations, and realistic future scenarios of marine environments in front of the currently changing climate. These scenarios can be used by planning agencies and national and international authorities for the elaboration of strategies to protect, but also to use of our natural marine environment. Geologists, oceanographers, mathematicians, computer scientists, and engineers, but also socio-economists are invited to join the session in order to present and to discuss new results in basic marine geosciences, as well as applications in disaster mitigation, coastal protection, exploitation of marine mineral resources and renewable and nonrenewable energy resources.

Remote sensing and geographical information system provide geospatial techniques to assess, monitor, and manage natural resources. The environmental and ecosystem services offered by the natural resources underpin the social and economic well being of the humans on the planet Earth. It is essential to monitor the changes in the status of natural resources and assess the dynamics of changes over space and time. The advancement in the field of remote sensing and GIS in the last few decades has enabled the scientific community to monitor the status and dynamics of the varied natural resources in different ecosystems all over the globe over space and time. Understanding of the historical changes and futuristic projections of the natural resources at various spatial and temporal scales is important to understand many of the land surface processes linked to hydrology, climatology, land degradation and other processes. Modeling in GIS environment using the inputs from remote sensing can help in understanding the patterns of change in natural resources and how human activities are impacting these changes and vice versa. The thematic session is proposed to deliberate on the latest development in application of geo-informatics in natural resource management.

Session 24: Sedimentary Basin Analysis
convenors: Daniel M. Tetzlaff

This session deals with the quantitative analysis, description, and modeling of the processes of erosion, transport, deposition, compaction and diagenesis of sediments as well as with post depositional basin processes such as heat flow, and hydrocarbon maturation and migration. The stratigraphic expression of primary depositional processes and its effect on the subsequent evolution of the basin fill are the main thread of the session. The focus is on quantitative methods and computer models developed by research, academic, and industry (mining and petroleum) groups with both an applied as well pure research goals. Emphasis will be placed on the feedback and interaction mechanisms that can give rise to complexity that cannot be explained by considering each process individually. Though the main subject is sedimentation, the session includes deterministic and statistical mathematical treatments as well as computer science issues that arise in the implementation of sedimentation models, making this session interdisciplinary.

Session 25: Modeling Aquifer Heterogeneities By Means of 3D-Geostatistics
convenor: Maria-Theresia Schafmeister
(schaf@uni-greifswald.de) Greifswald University, Germany.

Solute transport strongly depends on aquifer heterogeneities with respect to properties, e.g. permeability or sorptive parameters. The major goals of this session are (i) to introduce geostatistical tools which are able to reproduce the heterogeneity of aquifers in 3d-space and (ii) to present first results, which represent 'analogues' of relevant aquifers word-wide.

Session 26: Observed changes in Himalayan Cryosphere
convenors: AL Ramanathan
(alrjnu@gmail.com) Jawaharlal Nehru University; Anil Kulkarni (anilkulkarni@caos.iisc.ernet.in) Indian Institute of Sciences, India.

The Himalayan Crosypshere region is too large and it is difficult to consider them as a single climatic region. Large climatic gradients occur from Eastern Himalaya to the western Karakoram over 2000 km of its length. In Eastern and central Himalayan glaciers were strongly affected by the monsoon precipitation as snow at high elevation. Further the Himalayan glaciers are surrounded by densely populated countries that are strongly dependent on water originating in the Himalayas. Climate change may cause considerable changes of water availability in river systems. However, the importance of meltwater from snow and ice to the total basin runoff varies. There is a lot of contradictory information published about the state and fate of the Himalayan glaciers. A proper understanding of the processes affecting them, combined with the diversity of climatic conditions and the extremes of topographical relief within the region etc will be addressed in the Session which help us to understand the changing dynamic in Himalayan cryopshere in the recent past.

Session 29: Agriculture, Environment & Ecosystems
convenor: Sudip Mitra
(sudipmitra@yahoo.com) Tezpur University, India.

Today, attaining food security is a major challenge to the most of the developing countries. Meeting this challenge is most likely to lead to marked conversion of forest and rangeland ecosystems. Increasing demand of water to sustain the required production is another challenge that this world is facing today and which could lead to over extraction of water and thus increases the impacts of natural disasters and the resultant loss of biodiversity. Intensification and diversification of agriculture can't be avoided at present context, but the absence of clear understanding of its impacts on the environment could lead to both immediate and long-term consequences that directly impact the livelihoods of the poor. Climate change will only multiply these impacts. Experts argue that mainstreaming ecosystem management approach into national agricultural and economic development plans is critically important to address the long-term sustainability of agriculture in the face of climate change.
