Description
Summary:•Disaggregated the supply-side of the livestock market by production systems and feeding regimes.•This enables the drivers of supply growth across regions and agro-ecologies to be better captured.•Impacts of environmental stress on livestock can be better understood and modeled this way . The various ways in which livestock production systems can be incorporated into economic, partial-equilibrium, multi-market models are presented, and the challenges outlined. A particular focus and illustrative case is livestock feed. Foremost among the challenges is the reconciliation of scientific understanding of livestock feed requirements and production characteristics with the available national data. Another challenge is in estimating herd structures. An economic, multi-market modeling approach is presented which has been widely used in policy analysis and advocacy, and an account is given of the necessary recent enhancements for addressing livestock.
