| Summary: | Nowadays desertification, as a global problem, affects many countries in the
world, especially developing countries like Iran. With respect to increasing
importance of desertification and its complexity, the necessity of attention
to the optimal combating-desertification alternatives is essential.
Selecting appropriate strategies according to all effective criteria to
combat the desertification process can be useful in rehabilitating
degraded lands and avoiding degradation in vulnerable fields. This study
provides systematic and optimal strategies of combating desertification by
use of a
group decision-making model. To this end, the preferences of indexes were
obtained through using the Delphi model, within the framework of multi-attribute
decision making (MADM). Then, priorities of strategies were evaluated by
using linear assignment (LA) method. According to the results, the
strategies to prevent improper change of land use (<i>A</i><sub>18</sub>), development and
reclamation of plant cover (<i>A</i><sub>23</sub>), and control overcharging of groundwater
resources (<i>A</i><sub>31</sub>) were identified as the most important
strategies for combating desertification in this study area. Therefore, it
is suggested that the aforementioned ranking results be considered in
projects which control and reduce the effects of desertification and
rehabilitate degraded lands. |
