Intensification of animal production systems over the last 20+ years has increased the consumption of human edible protein by livestock, leading to increased competition for and cost of human edible protein. Grassland based agriculture, in a large part, supports ruminant production systems, which convert human inedible proteins (grassland) into human edible meat and dairy products of high protein and other nutrient value. Grassland-based systems have conversion efficiencies of 2.5 to almost 4 in terms of kg human edible protein produced for each 1 kg human edible protein consumed by livestock. Grassland offers a range of other ecosystems services including supporting plant and animal biodiversity, water resource management (e.g. water retention, provision of flood plains, filtering), carbon storage and sequestration, promoting soil health, sustaining rural communities, and contributing to rural culture and landscape management. Sustainable grassland management addresses the requirements of grassland to contribute to global net food security, particularly through ruminant production, as well as environmental conservation and management.
