A module characterisation for the agriculture and food sectorAbstract
In recent years, the Western European MARKAL-model has been extended with a materials system module covering the whole life cycle 'from cradle to grave'. This model including energy and materials is called MATTER 1.0 (Gielen, Gerlagh and Bos, 1998). This document describes a further extension with an agricultural module, called MATTER 2.0.
Ten agricultural crop types are considered which cover about 90% of the agricultural land use in Western Europe. The pastures alone cover about 40% of the agricultural land use. Land quality and land productivity has been considered through a split into three regions: North and Middle Europe, Southern Europe high yields and Southern Europe low yield. The split for Southern Europe is important because 50% of the land area in Southern Europe that is characterised as agricultural land has actually a very low productivity because of water availability constraints and mountainous topography. Generally speaking, yields in Middle Europe are higher than the yields in Southern Europe. Three quarters of the land use can be allocated to animal products: meat, dairy products, eggs and wool. Most important agriculture greenhouse gas (GHG) emissions considered within the model are methane (CH4) and nitrous oxide (N2O). Total emissions for these gases are around 350 Mton CO2 equivalents. This equals to 9% of the Western European GHG emissions. The main sources are:
