9.2.6 <strong>Dairy</strong><strong>in</strong>g <strong>and</strong> climate change<br />

The dairy sector has a two-way relationship with the environment. On the one h<strong>and</strong><br />

it is implicated <strong>in</strong> the production of greenhouse gases <strong>and</strong> contributes to climate<br />

change. On the other h<strong>and</strong>, dairy production is affected by the availability of natural<br />

resources <strong>and</strong> must adapt to climate change.<br />

Greenhouse gas production, while important, is currently hav<strong>in</strong>g limited impact<br />

on decisions about dairy-<strong>in</strong>dustry development because no economic <strong>in</strong>struments<br />

are be<strong>in</strong>g applied to carbon reduction <strong>in</strong> the dairy sector. Chapter 8 mentions the<br />

grow<strong>in</strong>g concern about the carbon footpr<strong>in</strong>t of all sectors, <strong>in</strong>clud<strong>in</strong>g agriculture.<br />

Rum<strong>in</strong>ants produce higher levels of greenhouse gases with<strong>in</strong> their life-cycles than<br />

poultry <strong>and</strong> pigs, but milk production produces less methane per unit of output than<br />

meat, <strong>and</strong> well-managed <strong>in</strong>tensively kept dairy animals produce lower volumes of<br />

methane per unit of prote<strong>in</strong> output than animals with a lower output (Henderson,<br />

Gerber <strong>and</strong> Opio, 2011). Small projects are explor<strong>in</strong>g the use of biogas digesters to<br />

manage manure <strong>and</strong> improved management of rangel<strong>and</strong>s <strong>and</strong> pastures to promote<br />

carbon sequestration as economically reward<strong>in</strong>g ways of offsett<strong>in</strong>g the greenhouse<br />

gas from extensive livestock (Chapter 8; Lipper, P<strong>in</strong>gali <strong>and</strong> Zurek, 2006; Mooney,<br />

2009). As Chapter 8 po<strong>in</strong>ts out, there are valuable discussions <strong>and</strong> analyses tak<strong>in</strong>g<br />

place with<strong>in</strong> the dairy sector <strong>and</strong> between <strong>in</strong>ternational agencies on ways to reduce<br />

emissions <strong>in</strong> dairy market cha<strong>in</strong>s. However, agricultural emissions are not currently
