Over the past two decades, significant investment has been made into
agriculture-related natural resource management research in developing
countries. With investors beginning to request the impact of their
investments in this research, a review was needed on the economic,
social and environmental effects of these projects. Stemming from an
effort to address these concerns, this collection of case studies
establishes a methodological foundation for impact assessments of NRMR
through a discussion of research conducted by the CGIAR around the
world. Both micro- and macroprojects are examined to consider the
results of these agricultural and development programs at the farm level
as well as on a regional scale.
