Developers: King's College London (models), AmbioTEK (software), CIATSEI, WWFUNAL (applications)

Audience: Conservation and development NGOs, GO and NGO Policy analysts, agriculture and industry (e.g. extractives), education and academic research.

Associated project(s): CGIAR Challenge Programme on Water and Food AN3 (Mechanisms for benefit sharing to improve productivity and reduce conflicts for water in the Andes)

Focus: CompAndes is a web based tool based on AguAAndes and is developed as a Negotiation Support System (NSS) for negotiations around benefit sharing mechanisms for water. This NSS is a testbed for negotiations around benefit sharing mechanisms for water focusing on sustaining equitable flows of water for all through appropriate land, ecosystem and water management. It is focused on enabling the intended and unintended consequences of benefit sharing mechanisms to be tested in silico before they are tested in vivo . The NSS incorporates detailed spatial datasets at 1-square km and 1 hectare resolution for the entire world, spatial models for biophysical and socioeconomic processes along with scenarios for climate and land use. The NSS calculates a baseline for current water provision and allows a series of interventions (policy options) or scenarios of change to be used to understand their impact on water delivery to people and environment. 

Though we provide input data for application of this model anywhere globally (from remote sensing and other global sources) users can also use this model with their own datasets.  Application with the provided datasets takes only half an hour and requires no GIS capacity.  Bringing in your own datasets will take much longer depending on the availability, level of processing, format and consistency of those datasets and also requires GIS capacity.

Typical applications include: negotiating PES schemes, trading off different water uses, understanding changes in water provision under  changed climate or land and water management.



Geographical coverage: global

Spatial resolution: 10 degree tiles @ 1km resolution or 1 degree tiles @ 1-hectare resolution

Temporal resolution: Monthly for baseline (1950-2000) and scenario

Development status: 
History: TAMMOD developed 1998, modified for FIESTA model 2004, modified for AGUAANDES 2007 and then COMPANDES 2011
Version 1: complete 
Version 2: ongoing - Let us know of new features you would find useful

Versions:
The version 1 model has a basic water balance (wind driven rainfall+fog - actual ET accumulated downstream as runoff) with land use and climate scenarios, see here

  
Version 2 has all the components of version 1 but also incorporates soil erosion, transportation, deposition and a snow and ice model as well as policy options for land management, see here
Current version 2 (model in development)

Version 3 is in development
