This paper first reviews trends in the recent evolution of investment
in national agricultural research systems. It then synthesizes the maj
or elements of an emerging paradigm for viewing the future evolution o
f research systems. This paradigm has arisen in response to the fundin
g crisis in public research organizations in the 1990s, and the declin
ing capacity of many of these organizations. Key elements of this new
paradigm are: a pluralistic institutional structure, a growing role fo
r the private sector, new mechanisms for research funding, improved ef
ficiency and effectiveness of public research organizations, and stren
gthening of global scientific links. (C) 1998 Elsevier Science Ltd. Al
