DESCRIPTION:Opinions over how to limit the immense impact of agriculture o
 n the rest of biodiversity are divided: is it better to retain on-farm wil
 dlife but at the cost of lowering yields\, or to increase yields\, limit t
 he area needed for farming and thereby retain larger areas under natural h
 abitats – or indeed something between the two?  Professor Andrew Balmfor
 d will introduce a model designed to answer this question\, and review the
  empirical evidence to date. He will conclude that this largely supports t
 he second\, so-called land-sparing approach to reconciling agriculture and
  farming\, but that important questions remain: over the generality of the
 se findings for different biota and for ecosystem services\, over how best
  to increase yields while limiting environmental externalities\, and over 
 how to couple yield growth to habitat retention and restoration.
