The LEAP (Livestock Environmental Assessment and Performance) Partnership is a multi-stakeholder initiative that is committed to improving the environmental performance of livestock supply chains, whilst ensuring its economic and social viability. LEAP develops comprehensive guidance and methodology for understanding the environmental performance of livestock supply chains.
The guidelines can be used by stakeholders in all countries to assess the sustainability of nutrient use in livestock supply chains. In particular, they are relevant to a wide array of livestock stakeholders including:
Livestock producers who wish to develop inventories of their nutrient use and to have the environmental performance of their production systems assessed;
Supply chain partners such as feed processors, livestock farming organizations, processors of animal products, as well as retailers pursuing a better understanding of the environmental performance of their production processes;
Policymakers that are interested in developing nutrient use accounting and reporting specifications for livestock supply chains.
To illustrate inventory data and results from a range of livestock systems, the guidelines include fours case studies: lamb production in New Zealand to consumption in the United Kingdom; beef and sheep extensive grazing system in Uruguay; egg (medium size) production, in combination with pigs and cereal production in Sweden; and fully grazing dairy cattle supply chain in Rwanda.
GLEAM is a modelling framework that simulates the interaction of activities and processes involved in livestock production and the environment. The model can operate at (sub) national, regional and global scale.
