Chapter
3: The
economics and psychology of desertification |

Risk
taking for profit or survival often leads to desertification. These
economic drivers must be addressed for long term success.
Intervention is essential for desert restoration because favorable
conditions for seed germination and early survival in many species
may only occur once in 5-10 years. Establishment and long-term
survival are often much more rare. Desert areas disturbed by human
activities may take centuries to recover without active intervention
to offset the adverse impacts. Plant recovery usually requires
planting activities and irrigation as well as site improvement and
seeding. Transplanting is increasingly used to provide nurse and
seed plants for disturbed areas. The dominant shrubs and trees of
the low desert are relatively easy to grow in a nursery or
maintained landscape setting and are well adapted to transplanting
with after-care.
One of the key lessons of the research that has been conducted is
the critical importance of minimizing disturbance.
