What is it?

CLEANED (Comprehensive Livestock Environmental Assessment for Improved Nutrition, a Secured Environment and Sustainable Development along Livestock Value Chains) is a rapid ex-ante environmental impact assessment tool that allows users to explore and make decisions about multiple impacts of developing livestock value chains.

Access the tool 

In what context is this tool useful?

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.  

CLEANED helps users to model the impact of changes in livestock production systems and value chains on land use, productivity, economics, water, greenhouse gas emissions and soil health so that they can make better decisions.

Results achieved

CLEANED has been applied to several 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.  A user-friendly R version with advanced GUI is under development and will be released soon.

Funding and implementation partners

The tool was developed by the Alliance, the International Livestock Research Institute (ILRI) and partners through initial funding from Bill & Melinda Gates Foundation as part of a pilot project in assessing environmental impacts on livestock production systems. Further development was funded through support by the Biotechnology and Biological Sciences Research Council (BBSRC), the CGIAR Research Program on Livestock and as part of the “Climate-Smart Dairy” project funded by the International fund for Agricultural Development (IFAD).
