To all working on landscape change and the integration of
agriculture into landscapes,
The current discussion on forest change may benefit from the following
Houghton, R. A., D.S. Lefkowitz, and D. L. Skole. 1991. Changes in the
landscape of Latin America between 1850 and 1985. I. Progressive loss of
forests. Forest Ecology and Management 38:143-172.
FAO [Food and Agricultural Organization]. 1996. Forest Resources
assessment 1990: survey of tropical forest cover and study of change
processes. United Nations, FAO, Rome, Italy.
FAO, 1997. State of the world's forests.
Richards, J.F. and E.P. Flint. 1994. A century of land-use change in
south and southeast Asia. Pages 15-66 in V. H. Dale, editor. Effects of
land-use change on atomspheric CO2 concentrations. Springer-Verlag. New
Also, the current issue of Ecological Applications (June, 2000 Vol. 10,
No. 3) has a special report on the state of landscape change from a variety of perspectives
(ag, forestry, economics). I think that this list could benefit from a reading
and discussion of this special section. What I get out of this is that
sustainable agriculture can benefit both from improving the on-farm
systems as well as realizing the role of farms as landscape elements in the
larger system. Water quality outcomes, in particular, might be an
important organizing framework for thoughts on this matter.
Biodiversity, landscape connectivity, soil quality, and watersheds stand
out in my mind as other important organizing topics.
