CLEANED – a new comprehensive framework for ex ante assessment of environmental impacts of livestock and aquaculture system interventions

This briefing describes CLEANED (Comprehensive Livestock and Aquaculture Environmental Assessment for Improved Nutrition, a Secured Environment and Sustainable Development along Value Chains), a rapid, ex-ante framework developed by a consortium including SEI, ILRI, CIAT, and CSIRO. The tool is designed to assess the potential environmental impacts of planned interventions in livestock and aquaculture systems, with a specific focus on smallholder agriculture in developing countries.

• CLEANED is a rapid, ex-ante framework designed to assess potential environmental impacts of planned livestock and aquaculture interventions across multiple spatial scales, specifically targeting the fragmented agro-ecological landscapes of smallholder systems in developing countries.
• The framework evaluates environmental impacts across the entire value chain, including the natural resource base for feed, livestock production, processing, marketing, and consumption, with a specific emphasis on waste management throughout the chain.
• CLEANED assesses four primary environmental impact categories: water availability and quality, soil and land health, biodiversity, and greenhouse gas emissions (measured in CO2 equivalents following IPCC guidelines).
• The tool is designed for general use with minimal expert knowledge, utilizing public global datasets for physical and climatic data (such as rainfall and topography) and complementing these with participatory geographic information systems (PGIS) and local surveys to increase context-specific accuracy.
• The framework produces final impacts as scores (adverse, positive, or static) for a discrete spatial unit—such as a watershed or district—and can disaggregate these scores to flag specific sensitive areas within a study domain.
• A 2014 proof-of-concept application of CLEANED in Tanzania analyzed dairy development and found that anticipated growth to meet rising milk demand would potentially put substantial new areas into fodder production.
• Globally, livestock and fish production are significant drivers of environmental change, contributing between 8.5% and 18% of anthropogenic greenhouse gas emissions and utilizing approximately 33% of arable land.
