Abstract

Baseline use is common in a variety of academic disciplines, including environmental science, but they are subjected to relativity depending on the geographical or historical reference considered. The measurement of livestock effects on climate change has, however, disregarded the use of baselines. Greenhouse gas emissions are not put in an ecological context. Grass-fed ruminant systems are hence in the spotlight because of high methane emissions, and conversion into intensive, grain-fed chicken and pork systems is
recommended.
We reviewed existing literature on baseline greenhouse gas emissions by wild ruminants, also considering the potential of termites, in filling herbivore niches in an ungulate-free scenario. Natural baseline scenarios would be of the same order of magnitude as current livestock scenarios. Current policy recommendations on livestock sector change are hence likely to be much less effective than currently thought. Similar considerations can be
applied on livestock impacts on water or biodiversity. Policy recommendations should take baseline levels into account, concentrate on reducing intensive use of fossil fuel and focus on methane reduction with social outcomes, such as the use of manure-fed biogas cooking stoves.
