Chapter 4:
Why the desert can't heal itself |
|
Many environmental factors can be degraded by human activity in the
desert and drylands. Many of these are interactive and synergistic,
making plant establishment perhaps 1% as likely as in an undisturbed
ecosystem. Assessing the nature and magnitude of changes in key
factors can improve restoration planning and reduce restoration cost
by enabling limited resources to be directed at critical problems.
Ongoing studies of the effects of these changes and their correction
through biological, chemical, or mechanical means will improve the
understanding of which factors are critical and those that are
relatively unimportant.
