Experimental Plan for climate biosphere coupling using RIMS1 and Century for Temperate East Asia. the experiment will implement a test of the sensitivity of climate dynamics to terrestrial biosphere. The initial experiment will use potential vegetation and FAO soil gridded to 50km resolution similar to POTSDAM global runs. Potential vegetation map will be provided as BATS classes with a look up table of Century classes to interpolate between BATS and Century vegetation classes (will use table of vegetation matching used for RAMS-Century simulations)
FAO soils will be provided gridded to the same resolution as the vegetation maps. Soil properties will be identified by soil texture classes, from original FAO data layer. Will also provide data related to % sand, silt, and clay of these FAO classes used by Century.
Domain of analysis will range from 10 - 55N and 90 - 145 E, which covers much of the LUTEA region. (Will get exact projection information from Fu's group).
Experiment to be conducted will follow this protocol:
| RIMS1 to simulate two case studies, a wet system and a dry
system, for one year each under a potential vegetation case (Vegetation map to delivered
by Ojima's group by January 10). This run will use the BATS land surface scheme as is. B)
RIMS1 will conduct the same experiment with FAO soils underneath potential vegetation map.
Congbin's group will complete this phase by end of February. |
|
| RIMS1 output of daily minimum and maximum T and precipitation
from four sets of simulations will be sent to Ojima by end of February. |
|
| Ojima will use the four climate data sets to run Century for the
region at 50km resolution to generate new LAI fields for the region. This will be
completed by March 10. |
|
| LAI sent to Congbin and four new set of climate runs are made
with new weekly LAI fields based on Century output. These simulations to be completed by
end of March. |
|
| Model comparison of climate fields related to surface
temperatures, precipitation, latent heat flux, sensible heat flux, and LAI between the
eight different simulated climates. Analysis will also look at regional and vegetation
summaries to evaluate relative forcing between different vegetation classes |
|
| Current vegetation gridded and aggregated map will be provide by middle of February by Ojima. Will also provide description of TEAL and potential vegetation maps used for Century modeling of Asian ecosystem dynamics. |
The region of Temperate East Asia has long been recognized for its wealth of natural and human resources. However recently, concern related to the changing environmental conditions in the region due to increasing human pressures degrading the environment have captured the attention of the scientific and political communities. The role of land use and land cover change in maintaining and in some cases leading to the degradation of the environmental health and sustainability of human welfare is a critical to the future of the region. The objective of this symposium is to highlight the various factors influencing land use in the Temperate East Asian region. Studies are being conducted by social and physical scientists on various aspects of the land use and land cover change issues and is being organized as a network on Land Use in Temperate East Asia (LUTEA) sponsored by the START Temperate East Asia Committee (TEACOM). The developments among scientists of the LUTEA network provides a mechanism for greater exchange of information useful for the scientific and the policy communities alike.

The impact of climate change on temperate ecosystems (such as croplands, grasslands, and forests) affects physical, ecological and socio-economic processes. Changes in these processes affects the soil fertility, soil moisture, and soil organic matter resulting in further regional land use and climate changes. These changes in land use and climate at the regional scale are often quite different from national or continental scale changes, so that regional differences are expected relative to land use decisions. Integrated assessments (IA) are needed to more completely model whole human-environment systems. IA efforts are under way that provide spatial and sectoral detail necessary to achieve reliable estimates of land use and ecological changes at county to regional scales.
The objectives here are: (1) to explore the development of an information linkage between a terrestrial ecosystem model and social economic data; (2) to describe the analytical framework to assess the importance of the critical human and environmental factors controlling land use decisions at local and regional scales. This presentation provides insight to the interactions of climate, ecosystem, economic and socio-cultural interactions controlling land use change at local to regional scales. The ability to analyze the integrated effects of the factors controlling ecosystem and socio-economic integrity relative to changes in climate and land use management of these ecosystems is a complicated task. A framework to simplify the complex interactions within and between various subsystems is provided using a modelling approach that includes all the major components and links them together in an integrated fashion. Development of this framework for assessing changes and incorporation of information to integrate factors controlling ecosystem and social-economic dynamics.
Technological advances in remote sensing (RS), geographic information systems (GIS) and ecological simulation modeling have increased our ability to link information across a broad array of disciplines. This ability has allowed us to begin to answer a variety of complex issues related to changing patterns of environmental and socio-political drivers in the Temperate East Asia. Since land use change is a dynamic process, the integration of GIS with simulation techniques provides a way to examine their spatial and temporal characteristics and identify forces contributing to land use change. The utility and information content of GIS and RS data depends on our knowledge of the socio-political, economic, and ecosystem structure and function. Thus, a way to increase the utility of RS and GIS data for interpreting land use-ecosystem process has been to combine RS and GIS with socio-economic and ecosystem modeling technologies.

The Pearl River Delta is presently one of the most developed areas in China. The high economic growth rates of the Delta have been accompanied by rapid industrialization and urbanization, and a very large and steady immigration from the rest of China since early 1980s. These trends have led to many problems in land use and environmental protection. Research into these problems will be very useful for sustainable development in this area, and in China too.
Population growth and consumption are key driving forces of land use change in this area. In order to explore the internal mechanism of land use dynamics, a better understanding of their interaction is necessary. In this paper, the basic relationship among population growth, consumption and land use change is described in the following diagram:
In the Pearl River Delta, the rapid population growth since early 1980s is mainly from immigration. Its impact on land use is through the change of consumption structure. The feedback impact of land use change on population growth is mainly through two links: ecosystem and economic development. Based on detailed analysis of the interacting process and consequence among population growth, consumption and land use change. The paper finally puts forward following recommendations for sustainable development in this area:
| Intensively utilizing land resource | |
| Determining a reasonable population size and preventing too fast population increase | |
| Reasonably exploring, utilizing, and protecting water resource | |
| Protecting agricultural land | |
| Paying much more attention to environment construction |

Many models can be used to simulate the temporal change of particular land use, such as cultivated land, grassland or forest. There are few models, however, which simulate the temporal changes for all land use categories. We developed a new land use change simulation model, GKSIM, to simulate the changes for all land use categories. GKISM satisfies the following conditions: each predicted area of land use does not exceed its marginal value determined by natural conditions or socioeconomic factors; the sum of all projected areas of land use always equals to the total area of the region studied; and, statistical test can be carried out. The way of how to run GKSIM step by step is illustrated, and its application for land use change in China up to 2050 is also introduced in this paper. The simulation result shows that forest and residential area will increase, while cultivated land and grassland will keep decreasing on the condition that current trend of land use change in China goes on.

Grasslands of the steppe are a critical resource for meat, milk, leather, wool, and cereal grains that provide subsistence for millions of people. We have characterized the factors controlling long-term ecosystem dynamics (soil C and fertility, plant production, water flux and etc.) and sustainable land use alternatives relative to changes in climate and land use management of the Mongolian steppe. The scope of the presentation includes analyses of existing information of recent historical patterns of plant productivity, grazing intensity, land use practices, human and livestock demographic patterns, economic growth and economic policies that determined local and regional land use systems. The analysis implements an interactive ecosystem-human socioeconomic system modeling framework. We are using this analytical framework to determine various strategies of sustainable land use in this region.
Historically, low population densities of nomadic pastoralists have used the rich grassland region to graze their mixed herds of cattle, sheep, goats, horses and camels. Grazing patterns were dictated more by intra- and interannual climate variability than political or economic factors. However, with changes in governments and in political controls on livestock demographic patterns, dramatic changes in land use have occurred. During the last 40 years, socialistic practices replaced many aspects of the traditional nomadic culture. The herdsmen were commonly organized into collectives and were allowed only a small number of animals for private ownership. The herdsmen moved less frequently, but for longer distances. In addition, human population levels in the region have risen dramatically during the past several decades. This has led to increased grazing intensity and rates of cropland conversion. Stocking rates around villages and water sources have increased. The most fertile land areas have been converted to croplands, and grazing has been shifted to fewer productive lands. This practice has intensified grazing on the remaining areas and has often reduced ecosystem productivity.
Since 1990, Mongolia has been converting from a socialistic centralized economy to a free market economy. These changes have affected the livestock's sector in a number of ways. A private ownership of animals increased to 94% and a total number of livestock increased from 25.8 million in 1990 to 31.3 million in 1997. Goat numbers increased from 5.1 million to 10.3 million at the same period because of the market value of cashmere. The number of the herders families increased from 75,000 to 184,000, with the largest growth of herders' families - almost doubling occurred during privatization of livestock in 1991-1992. The number of herdsmen nearly tripled for 1990-1997, reaching 410 thousands.
Land use changes in Mongolian grasslands modify biological constraints (plant nutrients and grazing) and will affect sustainability of the grazing system in the Mongolian Plateau. The traditional management of the rangelands sustained for centuries, but changes in land use during the last several decades are apparently increasing rangeland degradation.

The impact of climate change on temperate ecosystems (such as croplands, grasslands, and forests) affects physical, ecological and socio-economic processes. Changes in these processes affects the soil fertility, soil moisture, and soil organic matter resulting in further regional land use and climate changes. These changes in land use and climate at the regional scale are often quite different from national or continental scale changes, so that regional differences are expected with in land use decisions relative to climate change. Integrated assessments (IA) are needed to more completely model whole human-environment systems. IA efforts are under way that provide spatial and sectoral detail necessary to achieve reliable estimates of land use and ecological changes at county to regional scales.
The objectives here are: (1) to explore the development of an information linkage between the CENTURY terrestrial ecosystem model and the agricultural sector model (ASM), an economic model, in order to assess changes in the human-environmental system of the temperate systems in response to climate change; (2) to describe the analytical framework to assess the importance of the critical human and environmental factors controlling land use decisions at local and regional scales. This presentation provides insight to the interactions of climate, ecosystem, economic and socio-cultural interactions controlling land use change at local to regional scales. Use of land manager (farmers and ranchers) surveys provide insight to factors affecting land use decisions that over-ride certain of the economic assumptions and changes the trend in land use within the temperate regions of Asia and the Great Plains of the United States. The ability to analyze the integrated effects of the factors controlling ecosystem and socio-economic integrity relative to changes in climate and land use management of the these ecosystems is a complicated task. A framework to simplify the complex interactions within and between various subsystems is provided using a modelling approach that includes all the major components and links them together in an integrated fashion. Development of this framework for assessing changes and incorporation of information to integrate factors controlling ecosystem and social-economic dynamics.
The integrated model needs to incorporate the extensive information that exists on current land use practices. This framework needs to link the ecological, social, and economical sectors within an integrated structure. Information needed include records of weather and plant productivity, land use history, and socio-economic trends. Many factors and decisions bear directly on land use, including what land units are available for grazing or cropping, the severity of the climate, price of various input and output commodities, cultural and political constraints to the type of cropping system, or livestock system. The use of linked social-economic and ecosystem models is an integral component to the assessment at both the regional and local scale of ecological and socio-economical integrity.
Technological advances in remote sensing (RS), geographic information systems (GIS) and ecological simulation modeling have increased our ability to link information across a broad array of disciplines. This ability has allowed us to begin to answer a variety of complex issues related to changing patterns of environmental and socio-political drivers in the Central US. Since land use change is a dynamic process, the integration of GIS with simulation techniques provides a way to examine their spatial and temporal characteristics and identify forces contributing to land use change. The utility and information content of GIS and RS data depends on our knowledge of the socio-political, economic, and ecosystem structure and function. Thus, a way to increase the utility of RS and GIS data for interpreting land use-ecosystem process has been to combine RS and GIS with socio-economic and ecosystem modeling technologies.
Modeling studies at various levels have been useful to investigate the specific interfaces between ecological and socio-economic and political sectors. These studies address issues related to climate change's impacts; to grazing impacts at the landscape scale; integration of multiple land uses; nomadic movements relative to ecological - climatic factors; and land use decision making and nomadic movements relative to social, political, economic, and demographic factors.
A regional model framework to integrate the effects of multiple land use practices that impact ecological integrity of the agroecosystems of the US has been developed that links agroecosystem in a spatially explicit manner. The agroecosystems of the southcentral US has a mixture of land use practices ranging from intensive agriculture (i.e., irrigated and fertilized croplands) to extensive use (i.e., grazing) of rangelands and woodlands. The spatial and temporal use of various landscape units for these different land use practices affects ecological integrity relative to soil fertility, plant production, water availability, and economic integrity relative to net economic gains integrated over the entire landscape and across the diverse land use practices. We plan to implement this scheme to the temperate Asian region.
Predictions of long-term agricultural and ecological sustainability in relationship to variations in livestock abundance, cropping types, and other land uses are needed to assess the full range of ecological impacts of agricultural development. These predictions require a synthesis of the long-term effects of livestock on forage plant production and survival; the effects of human wood use on woody plant populations; the direct and indirect effects of livestock on soil structure and fertility; and agricultural use of water, soil, other resources, and technologies.
Implementation of a spatial modeling and remote sensing scheme over larger areas will require a larger network of information flow. Monitoring over larger regions can be achieved through a hierarchically organized system where information flows upwards from local studies to provide assessments over larger spatial areas. Local information is integrated to understand region-wide response to environmental conditions. Spatial variations in landscape properties must be integrated with ecosystem processes to understand or predict the dynamics of the agroecosystems.
