Resumen
Descripción
Global production of pork has doubled in the last three decades. Demand for pork projected to rise by 32% by 2030, which will put additional pressure on natural resources. This is of particular concern since the livestock sector already has a major impact on natural resources, using about 35% of total cropland and about 20% of green water for feed production. Hence there is growing interest from the pig and other sectors in measuring and improving environmental performance. There are wide diffe rences in the scale, goals and types of system that produce pigs. This diversity means that there is a great variety of production systems with different production intensities and purposes within and among countries. Conscious of these challenges, LEAP Partnership established in 2015 a technical advisory group to develop comprehensive guidelines on the assessment of the environmental performance of pig supply chains.
