La rivi\u00e8re Hana est le principal cours d\u2019eau traversant le Parc national de Ta\u00ef (PNT) de l\u2019Est vers l\u2019Ouest. Cependant, les diff\u00e9rentes sources de la rivi\u00e8re Hana font l\u2019objet de plusieurs pressions li\u00e9es \u00e0 la pollution due \u00e0 l\u2019orpaillage et aux effluents agricoles. Cette situation a pour cons\u00e9quence la d\u00e9gradation des \u00e9cosyst\u00e8mes environnant le cours d\u2019eau. L\u2019objectif de cette \u00e9tude est de mettre en place un plan de restauration \u00e9cologique du paysage des sources de la rivi\u00e8re Hana.<\/p>\n<\/div>\n<\/div>\n\n\n\n

Pour atteindre cet objectif, une actualisation des donn\u00e9es cartographiques a \u00e9t\u00e9 r\u00e9alis\u00e9e afin de d\u00e9terminer la dynamique du paysage de la source de la rivi\u00e8re Hana de 2021 \u00e0 2024. Par ailleurs, des enqu\u00eates individuelles r\u00e9alis\u00e9es aupr\u00e8s des riverains, combin\u00e9es aux observations directes sur le terrain ont \u00e9t\u00e9 effectu\u00e9es et ont permis de d\u00e9crire les principales activit\u00e9s anthropiques n\u00e9fastes \u00e0 un bon fonctionnement des diff\u00e9rents \u00e9cosyst\u00e8mes du paysage et d\u2019identifier les activit\u00e9s agro\u00e9cologiques r\u00e9alis\u00e9es autour de la rivi\u00e8re Hana.<\/p>\n\n\n\n

prenantes conviennent de l\u2019importance de restaurer le paysage autour de la source de la rivi\u00e8re Hana. Les principales zones \u00e0 restaurer sont les sites d\u2019orpaillage et les plantations situ\u00e9es dans les environs de la source de la rivi\u00e8re. La compilation des travaux sur la cartographie de l’utilisation du sol, l’identification des types de d\u00e9gradation et l\u2019aspiration des populations vivant dans le paysage de la rivi\u00e8re Hana a permis d’\u00e9tablir un plan de restauration \u00e9cologique. Ce plan met en exergue l\u2019am\u00e9nagement de deux types de milieu \u00e0 savoir cinq (05) sources et 114 hectares de berges. Des constructions de bo\u00eetes de captage, des constructions de retenues, des zones de reboisement, des cultures en agroforesterie ainsi que des zones de mise en d\u00e9fens ont \u00e9t\u00e9 propos\u00e9es dans le plan de restauration.<\/p>\n\n\n\n
