Available in PDF, EPUB and Kindle. Book excerpt: This book covers the subject of grasslands used for grazing livestock. Grasslands can be split into improved and unimproved pastures (also a sub-set of rangelands). Land used for livestock industries occupy 70% agricultural land and about 40% of total land and produce 40% of agricultural gross domestic product (FAO, 2005; Steinfeld et al., 2006). Increasing populations and incomes, coupled with a change in diets and urbanisation in the developing world, is enhancing demand for pasture-based products (Devine, 2003; Schmidhuber and Shetty, 2005). For example, milk and meat production is predicted to double to just over 1 billion tonnes of milk and 465 million tonnes of meat by 2050 (Steinfeld et al., 2006). To meet these demands most effort will go into intensification of improved pastures, which translates into high stocking densities supported by large inputs of fertilisers, feed supplements and energy.
