CLEANED is an ex-ante tool that assesses environmental impacts of livestock systems and value chains.  It evaluates land requirements, productivity, water use, soil health, economics and greenhouse gas emissions. 

As a result of population growth and shifting dietary patterns, the demand for livestock products is expected to rise. The predicted demand increase poses a danger that the necessary rise in livestock production could become unsustainable. It is important to assess current and future environmental impacts of the livestock value chains and use the assessment results to inform livestock development.

Funding and implementation partners

The tool was developed by CIAT, ILRI and partners through initial funding from Bill & Melinda Gates Foundation (DCE23232) as part of a pilot project in assessing environmental impacts on livestock production systems. Further development was funded through support by the BBSRC (BB/L026503/1), the CGIAR Research Program on Livestock and as part of the IFAD-funded “Climate-Smart Dairy” project. 

Results achieved

CLEANED has been applied to a number of projects in sub-Sahara Africa. Send a cow collaborated with a team of experts from CIAT to assess land requirements for a dairy cow under different feeding regimes and explored the trade-offs between these strategies in four counties in Western Kenya using CLEANED model. The tool has also been used in Tanzania, Burkina Faso, Ethiopia, Nicaragua, Honduras and Vietnam to assess the environmental impacts in dairy, beef and dual-purpose cattle value chains. 

Next steps/variations

CLEANED was originally developed as a flexible excel tool, applicable in any context.  Two context-specific R versions were developed for Ethiopia and Burkina Faso.  Currently a user-friendly R version with advanced GUI is being developed and expected to be released in 2021.
