    The Technical Advisory Group (TAG) for Water Use Assessment, composed by 30 international experts, has developed guidelines on water footprinting for livestock supply chains. The mandate of the Water TAG was to provide recommendations to monitor the environmental performance of feed and livestock supply chains over time so that progress towards improvement targets can be measured; apply the guidelines for feed and water demand of small ruminants, poultry, large ruminants and pig supply chains; build on and go beyond the existing FAO LEAP guidelines; and pursue alignment with relevant International Organization for Standardization (ISO) standards, specifically ISO 14040, ISO 14044 (ISO, 2006b and 2006a) and ISO 14046 (ISO, 2014). The guidelines on water use assessment include the impact assessment: the assessment of the environmental performance related to water use of a livestock-related system by assessing potential environmental impacts of blue water consumption following the water scarcity footprint according to the framework provided by ISO 14046 (ISO, 2014); and the assessment of the system’s productivity of green and blue water. The guidelines are thus intended to support the optimization of use of water resources and the identification of opportunities to decrease the potential impacts of water use in livestock production. The Water TAG guidance is relevant for livestock production systems, including feed production from croplands and grasslands, and production and processing of livestock products (cradle-to-gate). It addresses all livestock production systems and livestock species considered in existing LEAP animal guidelines: poultry, pig, small ruminant and large ruminant supply chains.

    Water use in livestock production systems and supply chains
    Summary of the guidelines for assessment

    There is a need for widely recognized frameworks for the assessment of the performances of feed and livestock systems and of livestock products to mitigate negative impacts on water resources. The goal of the methodology developed in these guidelines is to introduce a harmonized international approach for assessing livestock production systems and supply chains. This work aimed at building consensus for water use assessment, in order to report blue water scarcity footprints and to identify actions for improvement in water management. The document is relevant for feed and livestock production systems, production and processing of livestock products (cradle-to-gate). It addresses all livestock production systems and livestock species considered in existing LEAP guidelines: poultry, pigs, small ruminants, and large ruminants supply chains.

    Environmental performance of feed additives in livestock supply chains. Guidelines for assessment

    The production and the use of feed additives influence the environmental impact of livestock production. The use of feed additives significantly acts on feed efficiency, and thus animal and environmental performance. The methodology developed in these guidelines aims to introduce a harmonized international approach to the assessment of the environmental performance of feed additives in livestock supply chains taking into consideration the impact of their production and use all along the supply chain for large ruminants, pigs and poultry. The objective of this technical document is twofold: on the one hand, to provide detailed guidance on how to measure the environmental performance of the production of feed additives, and on the other hand, how to measure the effects of feed additives on the environmental performance of livestock products. The guidelines on the environmental performance of feed additives in livestock supply chains are intended to be used with other published LEAP guidelines.
