Towards an Integrative and Sustainable Science Program for Caspian Sea Environment
Sassan S. Saatchi Senior Scientist UCLA/Institute of Environment NASA/JPL California Institute of Technology
Collaborators: Qiang Fu, UCLA/Geography Dept. (PhD Student) Ali Nouri, UCLA/Institute of Environment (Postdoc) Soleiman Mohamadi, Gilan University, Iran Dara Entekhabi, MIT Babak Hedjazi, University of Geneva Caspian Sea Environment The Caspian Sea basin is rich with diverse aquatic, avian and terrestrial wildlife, and has a variety of ecosystems with unique and fragile hydrological and ecological characteristics.
1. Largest land-locked body of water on earth 2. Caspian drainage basin is ~ 3.5 Million km2 1. (world’s largest watershed, and annual runoff) with 130 rivers flowing into the sea with Volga contributes 80% of runoff. 3. Being a closed body and large basin, the system can filter high frequency water budget and is a good indicator of interdecadal and long term climate change 4. Being a closed system hydrological and biogeochemical processes are intimately linked (water, energy, resources) Any changes in land impacts the hydrology and ecosystem & vise versa. 5. The basin is diverse in ecosystems, natural habitats, large river systems, major wetlands with high level species endemism and diversity. 6. Caspian has drastic sea level change due to climate and hydrological processes. Caspian Sea Environment Proposal Objectives
Fundamental Questions: 1. How does Caspian Sea Function as an entity (e.g. hydrological & Ecological system)? 2. To what extent human developments (past, present, future) impacts the environment? 3. What is the interaction of Caspian Sea Region with regional and global Climate?
Specific Science Questions:
1. What is the impact of human induced changes of land, sea and coast on Caspian Hydrological and Ecosystem Function? 2. How does regional and global climate change and variability impact the Caspian ecosystem? 3. How can regional development be sustained along with the Caspian conservation of resources and nature?

Assessment of impacts of land cover Land use change on Caspian Sea Watershed hydrology integrated remote-sensing and modeling system & training 1. watershed and water resource health, 2. spatial and temporal variability in regional water fluxes 3. potential change in groundwater recharge/resources, 4. potential change in evaporative flux 5. potential change in surface water runoff (retention basin loss), 6. potential impact of increased urbanization 7. Identify gaps in potential data and information requirements 8. Identify stakeholders and human factors through a series of metrics Phase II Simulations of Caspian Hydrology
Use of geographically distributed model to model the closed basin hydrology to capture linkages and possible feedbacks between land hydrology, synoptic atmospheric circulations, and physical and biological limnology of the Caspian Sea and its watershed.
The over schematic of the tRIBS-VEGGIE architecture: a) Example of a TIN representation of topography within the distributed (spatial) watershed model, b) an unstructured grid cell representation of the model with water, energy and biospheric processes, and c) A conceptual diagram of carbon fluxes simulated by the model (Ivanov et al., 2008a). LAND USE AND LAND COVER CLASSIFICATION AND CHANGE DETECTION OF THE CASPIAN SEA BASIN
The forests of southern Caspian region in Iran is considered the remnants of Hyrcanian vegetation zone within the Euro- Siberian region and is considered the largest forest patch within the Caspian Sea basin. The vegetation zone is a green belt stretching over the northern slopes of Alborz Mountains stretching from southern Turkmenistan from the east to southern Azerbaijan Landsat ETM circa 2000 in the west Changes of Forest Cover Observed by Landsat Summary
• Deforestation and land cover and land use change are extensive in particular in southern Caspian region with areas of forests being replaced by urban and agricultural land.
• We have processed MODIS data over about 10 years and analyzing it to quantify LCLUC over the entire Caspian Sea Basin from 2000-2010.
• Surface parameterization for spatial hydrological model has been completed. We are submitting our second phase proposal to develop the model and examine the impact of land use and climate over the basin.
Summary
Data consolidation and harmonization . We show how we have integrated multidisciplinary data streams from multiple projects spanning several domains. This has proven to be a powerful analysis tool for researchers and students
Analysis of water cycle components and impacts . We have made historical analysis of changes in water cycle components, land cover and water use across NEESPI region. Climate plays major role in most regions of NEESPI
Future projections . We have analyzed IPCC scenarios from different AO GCMs and found a wide variability in precipitation projections for the region . Results of simulations with UNH water balance models using different AO GCMs climate projections show more consistent changes in hydrology . Preliminary projections of future water balance show wetter climate and higher runoff for most NEESPI region except Central Asia and Southern Europe where it is opposite.
