Accelerating Degradation of Transboundary Ecosystems
In the traditional uses of the main ecosystems of the
area, human activities have exerted pressures on the environment and
resulted in conflicts among the various groups involved, with negative
consequences for the quality of water resources. These consequences
include inadequate urban, industrial, and agroindustrial wastewater
treatment systems; migratory agriculture, extensive grazing and the
consequent extension of the agricultural frontier; widespread cutting of
trees for timber, unregulated ecotourism, non-conservationist farming
practices, the introduction of aggressive exotic species such as Tilapia
mossambica; and uncontrolled fires in the drier forests and of grassland.
An emerging problem is the growing use of small and very small hydropower
plants to tap the considerable hydroelectric potential of the region.
