The analysis of the landscape can serve to value human actions on soil in the Lwiro region. The approach of the indicators bound to the management of soil in the region is not well stocked enough.

The species indicator of infertile soil represents a negligible percentage (Imperate cylindrica 0,5% Guizotia scabra 0,6% Tagetes minuta 0,8% Rhychelytrum repent 1%) except Conyza sumantrensis 5%, Crassocephalum vitellinum 3%. broadly speaking the indicators bound to the management of soil in the region of Lwiro are represented better in Byalumba that in Muganzo and Tshibati. the agriculturists provide an effort to palliate to the difficulties bound to the management of the fields. The depth of soil is big in Byalumba 54cm follow-up of Muganzo 40cm and Tshibati, 38cm.

Abstract
The analysis of the landscape can serve to value human actions on soil in the Lwiro region. The approach of the indicators bound to the management of soil in the region is not well stocked enough. These criteria had been verified by the direct observation of the intervention sites in relation with geology by simple and open questions to people of the village met for enlightenments on the state of soil by a transverse walk. The species indicator of infertile soil represents a negligible percentage (Imperate cylindrica 0,5% Guizotia scabra 0,6% Tagetes minuta 0,8% Rhychelytrum repent 1%) except Conyza sumantrensis 5%, Crassocephalum vitellinum 3%. broadly speaking the indicators bound to the management of soil in the region of Lwiro are represented better in Byalumba that in Muganzo and Tshibati. the agriculturists provide an effort to palliate to the difficulties bound to the management of the fields. The depth of soil is big in Byalumba 54cm follow-up of Muganzo 40cm and Tshibati, 38cm.

Abstract: (french)
L'analyse du paysage peut servir à l'effet des évaluer actions anthropiques sur le sol dans la région de Lwiro. L'approche des indicateurs liés à la gestion du sol dans la région n'est pas assez fournie. Ce critère a été vérifié par l'observation directe des sites d'intervention en rapport avec la géologie par des questions simples et ouvertes auprès des personnes du village rencontrées pour des éclaircissements sur l'état du sol par une marche transversale. Les espèces indicatrices de sol stérile représentent un pourcentage négligeable (Imperate cylindrica 0,5% Guizotia scabra 0,6% Tagetes minuta 0,8% Rhychelytrum repens 1%) hormis Conyza sumantrensis 5%, Crassocephalum vitellinum 3%. D'une façon générale les indicateurs liés à la gestion du sol dans la région de Lwiro sont mieux représentés à Byalumba qu'à Muganzo et Tshibati. les agriculteurs fournissent un effort pour pallier aux difficultés liées à la gestion des champs. La profondeur du sol est grande à Byalumba 54cm suivi de Muganzo 40cm et Tshibati, 38cm.
Author Keywords: étude, plantes indicatrices, activités humaines, Irhambi/Katana.
