Models, tools, and data

Research models of the Biodiversity and Natural Resources Program.

Hybrid Land Cover of Russia

A system integration of ground and remote sensing data that parametrizes Russian territory at a 1km spatial resolution for forests and includes tree species, age, and biomass distribution. More


A model that optimizes the allocation of renewable energy systems from the local, regional, national or European level. More

The Global Forest Model (G4M)

Comparing incomes from forestry and alternative land uses More

The Environmental Policy Integrated Model (EPIC)

A model assessing how land management affects the environment More

Russian Forests and Forestry Database

Comprehensive downloadable data and analysis on the Russian forestry sector More

Global Forest Database

Downloadable global forest map at a half-degree resolution More

Global Agro-ecological Zones (GAEZ)

Detailed assessment of available resources to support policymakers developing national, regional, and global strategies for the sustainable production of food More

Harmonized World Soil Database (HWSD v 1.21)

HWSD is a global soil database framed within a Geographic Information System (GIS) and contains up-to-date information on world soil resources. More


A model that traces land and water use embodied in production, trade and consumption of agricultural commodities. More

FeliX Model

A system dynamics model of social, economic, and environmental earth systems and their interdependencies. More


The wildfire climate impacts and adaptation model (FLAM) is used to reproduce historical and to project future burned areas, as well as to assess climate change impacts and adaptation options. More


A global model to assess competition for land use between agriculture, bioenergy, and forestry. More

BioGeoChemistry Management Model (BGC-MAN)

Assessing management impacts on the BioGeoChemistry of ecosystems More


The IIASA/ESM based BGC-MAN model was calibrated and validated with TrEco data for the dominant ecosystems and land use forms of the Congo basin, including virgin forests, managed forests, forest fallows after shifting cultivation and savannahs. More

Global Hydro-economic Model (ECHO)

A new tool to inform the design of cost-effective and sustainable water policy decisions. More

Community Water Model (CWatM)

An open source model to examine how future water demand will evolve in response to socioeconomic change and how water availability will change in response to climate. More


A general equilibrium model to assess China’s agricultural prospects and challenges up to 2030, covering national, regional and county level. More

Probabilistic approach to address temporal verification of changes in global net carbon emissions under the Kyoto Protocol

This study proposes an approach which permits assessing net emission changes under the Kyoto Protocol, in particular with respect to atmospheric CO2 and CO2 emissions from fossil fuel burning, cement manufacture and gas flaring; whereby emission changes are characterized by uncertainty distributions in terms of verification times (VTs).  More

Stochastic Quasigradient (SQG) methods: Applications

Stochastic Quasi-Gradient (SQG) methods have been developed for solving general optimization problems without exact calculation of objective function and constraints (let alone of their derivatives). SQG methods enable a sequential revision of approximate solutions towards the optimal using newly acquired information on the system, obtained via either direct on-line observations or(and) simulations.  More

Consistent algorithm for linking distributed models under asymmetric information

The linkage algorithms solve the problem of linking models, e.g. sectorial and/or regional, into an inter-sectorial inter-regional integrated model. Linkage enables to avoid “hard linking” of models in a single code, which saves the programming time and enables parallel distributed computations of individual models instead of a large scale integrated model. Models linkage preserves the structure of the original models taking into account critically important details, which are usually missing in aggregate models More

Water Quality Modeling

Water quality modeling for water availability/scarcity assessment, water-energy-land-environment nexus analysis and identification of cost-effective solutions under long-term changes. More
