      abstract = {Recent trends in farm productivity and food prices raise  concerns about whether the era of global
agricultural  abundance is over. Agricultural R&D is a crucial  determinant of agricultural
productivity and production,  and therefore food prices and poverty. In this paper we  review past
and present agricultural production and  productivity trends and present entirely new evidence  on
investments in public agricultural R&D worldwide as an  indicator of the prospects for
agricultural productivity  growth over the coming decades. The agricultural R&D world  is
changing, and in ways that will definitely affect future  global patterns of poverty, hunger and
other outcomes. The  global picture is mixed. In the world as a whole crop yield  growth has
slowed. In high-income countries productivity  growth has slowed significantly, and real
spending on  agricultural R&D is being reduced. In China, and other  middle-income countries,
spending on agricultural R&D is  being ramped up and productivity growth has not slowed.  The
overall picture is one in which the middle-income  countries are growing in relative importance as
producers  of agricultural innovations through investments in R&D and  have consequently better
prospects as producers of  agricultural products.},
