Irhambi/Katana situated in the territory of Kabare, province of the South-Kivu (R.D. Congo) is among the main region supplier the city of Bukavu in agricultural product. Our objective is to identify while valuing the sources of deterioration of the observable or measurable earths by the scientists and the farming environment and to put them in relation with the indicators recognized and used by the agriculturist, concerning the quality of the soil of Katana. The survey that lasted 12 months is achieved according to a methodological gait that is inspired by the inventory approach. This inventory consisted to visit the intervention sites (villages) by a transverse walk (transect walk) while following Horizontal axes to identify the sources of deterioration of the soil.
The level of appreciation of these sources of deterioration made itself by free observation with simple and open questions by people of the village met for enlightenments on the state of deterioration of the soil. Our results show that the erosion (60%) to eat the herbs abusively (50%) constitute a problem of management of the soil in Kajuchu; the domestic garbage threa ten the terrestrial environment in Mwanda (45%). The source of soil deterioration identified in the present work will be an indicator privileged to allow farmers to decide the opportunity to exploit or no their soil.

Irhambi/Katana situated in the territory of Kabare, province of the South-Kivu (R.D. Congo) is among the main region supplier the city of Bukavu in agricultural product. Our objective is to identify while valuing the sources of deterioration of the observable or measurable earths by the scientists and the farming environment and to put them in relation with the indicators recognized and used by the agriculturist, concerning the quality of the soil of Katana.

Abstract: (french)
Le groupement d'Irhambi/Katana situé dans le territoire de Kabare, province du Sud-Kivu (R.D. Congo) est parmi les principaux groupements pourvoyeur en produits vivriers de la ville de Bukavu. Ce travail a pour objectif identifier tout en évaluant les sources de dégradation des terres observables ou mesurables par les scientifiques et les aménagistes du milieu rural et les mettre en relation avec les indicateurs reconnus et utilisés par les agriculteurs, concernant la qualité des terres de Katana. L'étude qui a duré 12 mois est réalisée suivant une démarche méthodologique qui s'inspire de l'approche d'inventaire. Cet inventaire a consisté en une visite des sites d'intervention (villages) par une marche transversale (transect walk) en suivant des axes Horizontaux pour identifier les sources de dégradation des terres.
Le niveau d'appréciation de ces sources de dégradation s'est fait par observation libre avec des questions simples et ouvertes auprès des personnes du village rencontrées pour des éclaircissements sur l'état de dégradation des terres. Nos résultats montrent que l'érosion (60%) et le surpâturage (50%) constituent un problème de gestion des terres à Kajuchu ; les déchets ménagers menace l'environnement terrestre à Mwanda (45%). La source de dégradation du sol identifié dans le présent travail sera un indicateur privilégié pour permettre aux agriculteurs de décider de l'opportunité d'exploiter ou non leur sol.
