Agricultural production increases, per commodity 1965-2008
Year:
2009
Author:
Hugo Ahlenius, UNEP/GRID-Arendal
Description:
The use of fertilizers accounts for approximately 50% of
the yield increase, and greater irrigation for another substantial
part (FAO, 2003). Current FAO projections in
food demand suggest that cereal demand will increase by
almost 50% towards 2050 (FAO, 2003; 2006). This can
either be obtained by increasing yields, continued expansion
of cropland by conversion of natural habitats, or by
optimizing food or feed energy efficiency from production
to consumption.
