Brève description de la meilleure pratique
High human and livestock population in the desert are leading to mismanagement of the sandy terrain causing reactivation and land degradation resulting of sand movement. This moving sand encroach productive agricultural fields, human habitation, canal, road and railway tracks. The most effective method was the control through a careful plantation of trees, shrubs and grasses. Calligonum polygonoides was the most suitable species, which provided better microenvironment and helpful in developing effective surface vegetation to control sand drift. Combination of C. polygonoides with Cassia angustifolia was best to control sand drift. These adult neighbours are also helpful to improve biodiversity and ecology of the arid areas. |

Sur la base de quel critère/indicateur(s) (sans relation avec la stratégie) la pratique proposée et technologie correspondante ont-elles été considérées comme « meilleures »?
Introduction of under shrubs and grasses along with the tree species could provide beneficial effects in controlling sand reactivation and drift, particularly, at the time when planted seedlings attain the size of a tree facilitating free air movement under the canopy resulting in reactivation of sand drift. Further, dunes are also deficient in soil organic matter and nutrients, particularly nitrogen. Therefore nutrient management practices can be adopted and sowing of leguminous and / or non-leguminous under shrubs or grasses to increase nitrogen and organic matter may be the important options. They not only increase the soil nutrient status but also provide fodder for livestock in addition to sand drift control |
