ThereceivedwisdominAndeanstudiesonenvironmentaldegradationandagriculturalintensificat... The received wisdom in Andean studies on environmental degradation
and agricultural intensification can be summed up in two propositions: absence
of ecological decomposition, and agricultural intensification is inversely
related to altitude. Despite population pressure, greater state penetration,
and growing market influence in the countryside (Orlove, 1977), high-altitude
farmland and grazing grounds in the Andes have not experienced much runoff
or erosion (Orlove, 1976, p. 208; Guillet, 1981, p. 150; in press). The absence of ecological disintegration, the first proposition explains, occurs because
of a reciprocal relation or dialogue between nature and cultural forms.
Sectoral farming and mixed agropastoral subsistence regimes require and underwrite
the formation of institutional structures and strong forms of communal
organization (Rhoades and Thompson, 1975). Village councils, in turn,
prevent unregulated exploitation of local resources. As a result, no environmental
degradation occurs. The second proposition holds that high-altitude
Andean soils, owing to their limited fertility, are poorly suited to sustain permanent
intensification. Since soil fertility decreases while natural risk factors
increase with elevation, agricultural intensification, when it occurs, tends
to be inversely related to altitude (Caballero, 1981; Guillet, 1981). These two
propositions need reappraisal.
Ecological Decomposition. First, the putative absence of ecological
degradation rests, in the main, on literature searches. Owing to the paucity
of ecological research in the Andes, and the proclivity toward viewing Andean
rural societies as well-adapted entities, it is not surprising to find a dearth
of information on ecological problems. Second, ecological studies in the
Andes tend to be inexcusably ahistorical (Winterhalder, Larsen, and Thomas
1974; Thomas, 1979; Guillet, 1981; Orlove, 1976). Synchronic perspectives
may give the illusion the Andes are an intact ecosystem, but inquiries
informed by historical considerations alert one to some of the stresses and
strains to which these haibtats have been subjected. Finally, there is growing
evidence which suggests that erosion in Andean nations may be serious. A
recent USAID (1980, p. ix) report, for instance, noted that over 80%fo f
Bolivia's highlands were badly eroded and overgrazed. Other studies suggest
that over half the surface area of the Andes in general may be likewise badly
bruised (FAO, 1954, pp. 16-17; Millones, 1982, p. 56; Caballero, 1981,
pp. 76-77, 82).
