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

The CLEANED framework provides a participatory, rapid assessment tool for evaluating the environmental footprints of livestock and aquaculture interventions across the entire value chain. It focuses on four main impact categories: water availability and quality, soil and land health, biodiversity, and greenhouse gas emissions. Designed for use in developing countries, the tool combines public global datasets with local participatory GIS data to provide scores (adverse, positive, or static) for specific spatial units. A pilot application in Tanzania's dairy sector demonstrated the tool's ability to visualize how increased milk demand could expand fodder production areas.

• The CLEANED framework is designed as a rapid, ex-ante tool to assess environmental impacts at multiple spatial scales for planned livestock and aquaculture interventions, 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 using specific indicators: water (availability, quality, and soil water-holding capacity), soil and land health (erosion, organic matter, and fertility), biodiversity (habitat pressure, species diversity, and genetic resources), and greenhouse gas emissions (methane, nitrogen oxides, and carbon dioxide equivalents based on IPCC guidelines).
• The tool is designed for general use with minimal expert knowledge, utilizing a combination of public global datasets (for climate, soil, and topography) and participatory geographic information systems (PGIS) to validate and collect local data.
• The framework outputs results as scores—categorized as adverse, positive, or static—which can be applied to a whole discrete unit (such as a watershed or district) or disaggregated spatially to identify specific sensitive areas.
• A proof-of-concept application in Tanzania's dairy sector showed that meeting anticipated milk consumption increases (projected to rise to 100 litres per capita by 2020) would potentially lead to substantial new areas being dedicated to fodder production.
• Global livestock and fish production are significant drivers of environmental change, contributing between 8.5% and 18% of global anthropogenic greenhouse gas emissions and utilizing approximately 33% of arable land and 37% of water allocated for crop production.
